    Figure 7: the forceps element according to the invention with Unterschraubmesser.
    FIG. 1 shows an exemplary embodiment of a wooden pliers, in which pliers elements 1 according to the invention are used. In the exemplary embodiment, the forceps elements 1 have a pivot axis 2, via which they are articulated to a connecting element 3. The opening and closing of the gripper formed in this way takes place via hydraulic cylinders 4, which are articulated via pivot axes 10 on the pliers elements 1 and on the connecting element 3.
    The pliers also have a rotary drive 5, via which they can be aligned. Furthermore, a pivotable suspension 6 is provided, via which the pliers can be attached to a gripping arm. In the embodiment, a free storage is provided, which is designed in the embodiment as kar-danische suspension.
    An inventive pliers element has in the exemplary embodiment two curved side regions 7, which define a receiving surface. In this case, a recess may be provided between the side regions 7 or a receiving base 11 which connects the side parts 7.
    The forceps element 1 ends in a cutting region with the base cutting edge 9. The base cutting edge 9 is arranged on a plate-like cutting element 8, which defines a nipper surface.
    According to the invention, different cutting edges can now be interchangeably attached to the base cutting edge 9. The pliers element itself thus represents a basic variant, which can be equipped for customer use by simply retrofitting the desired main cutting edge. In addition, the main cutting edge can also be changed during use.
    The basic cutting edge 9, to which different main cutting edges can be fastened, is shown only schematically in FIG. 1 and will now be explained in more detail with reference to the exemplary embodiment of a forceps element according to the invention shown in FIGS. 2 to 7.
    Regardless of the detachable connection of the main cutting edge to the base cutting edge via screw connections, which is described in more detail there, the present invention is not limited to the following: ## EQU3 ## It is crucial that the connection between the base cutting edge and the main cutting edge can be made without welding or firing. For this purpose, appropriate connection means are provided.
    FIG. 2 shows the embodiment of the forceps element according to the invention with four different main cutting edges 12 to 15. The pliers element in turn has two curved side parts 7, between which a pliers bow 11 extends. Furthermore, the linkages 2 can be seen for the pivotable articulation of the tong element and the linkage 10 for the hydraulic cylinder.
    The cutting area is formed by a cutting element 8, which is designed plate-shaped and defines a nipper surface. At the front edge of the forceps element 8, the basic cutting edge 9 according to the invention is arranged. At this base blade 9, the four different main cutting edges 12 to 15 shown in Figure 2 can be releasably attached. The attachment is done by screwing.
    The four main cutting edges shown in FIG. 2 are a roller blade 12, a shaft cutting edge 13, a main cutting edge with cutting edge 14 and a blade with a sub-blade blade. Of course, according to the invention, however, only two or three of these different main cutting edges can be used. The cutting element 8 with the different main cutting edges 12 to 15 attached to the base cutting edge 9 is again shown in FIG. 3 for the sake of clarity.
    The construction of the cutting element or of the base cutting edge and of the individual main cutting edges will now be described in more detail with reference to FIGS. 4 to 7:
    FIG. 4 shows the use of the forceps element according to the invention with a roller blade as the main cutting edge. The roller blade consists of an axis 17, on which rollers 18 are rotatably arranged. The axis 17 is screwed in the areas between the rollers 18 with the base blade.
    For this purpose, the base cutting edge projections 20, with which the axis 17 is screwed, and recesses 19, in which the rollers 18 are arranged with a certain play, so that they can rotate.
    The screw connection between the main cutting edge and the base cutting edge takes place in the same way for all main cutting edges: In the main cutting edge, threaded bores 21 are provided on the side facing the base cutting edge. These are designed as a blind hole, so that the front of the main cutting edge has no openings. The base cutting edge in turn has corresponding bores on its side facing the main cutting edge, which bores extend into the cutting surface of the cutting element 8. The holes 22 open into recesses 16 in the cutting surface.
    The screwing takes place via threaded rods 23, which are screwed into the threaded holes 21 of the main cutting edge. The threaded rods 23 extend through the holes 22 in the base cutting into the recesses 16th
    There, nuts 24 are screwed onto the threaded rods 23, by which the main cutting edge is fixed to the base cutting edge.
    As an alternative to the arrangement shown with threaded rods 23 and the use of screws would be conceivable, for which, however, larger recesses 16 in the cutting surface would be necessary to push them from behind through the holes 22. In the present embodiment, however, the threaded rods 23 can be pushed from the front through the bore 22 and then screwed into the recesses 16 with nuts 24.
    The embodiment of the base cutting edge 9 in the region of the support surface for the main cutting edge can be seen particularly well in FIG. 5, which shows the cutting element with the shaft cutting edge screwed on as the main cutting edge. The bearing surface 27 • * * * i * C ff # * «* I a · ft» «♦ • ft · · * ·· ·· * · ft > The basic cutting edge is designed concave, in the exemplary embodiment as a prism. *** " The counter-bearing surface 28 of the main cutting edge, however, is convex. This results in a positive connection, which defines the main cutting edge in addition to the screwing in a direction perpendicular to the screwing. Furthermore, the main cutting edge is thus pulled into the concave support surface 27 of the base cutting edge and centered during screwing.
    The bearing surface of the main cutting edge can be designed to be round, as is the case, for example, in the case of the roller blade shown in FIG. 4 and in the shaft cutting edge shown in FIG. The shaft cutter 26 consists simply of a round rod with corresponding holes 21. Likewise, the axis 17 of the roller blade, which is shown in Figure 4, consists of a round rod with such holes. As a result, a particularly simple and cost-effective production of the corresponding main cutting edges is possible.
    FIG. 6 shows a main cutting edge 29 with a cutting edge 31. The cutting edge 31 is made blunt and has a straight front surface and bevelled edges. The counter-bearing surface 30 of the main cutting edge 29 is like the support surface 27 of the base prismatic, which allows an even more stable screwing.
    Furthermore, the main cutting edge 29 shown in Figure 6 with holes 32 which are perpendicular to the nipper surface, equipped to equip the nipper element with a Unterschraubmesser. Also, the cutting element 8 is provided with such holes 25 which pass through the nipper surface.
    In Figure 7, a corresponding Unterschraubmesser 33 is now screwed. The Unterschraubmesser 33 in this case has bores 34, through which screws 35 are screwed from below into the holes designed as a threaded bore 32 and 25 in the main cutting edge or in the base cutting edge. In the exemplary embodiment, the Unterschraubmesser 33 is thus bolted to both the main cutting, and with the cutting element 8. Alternatively, however, a screw connection with only one of the two elements would be conceivable.
    The bores 25 in the cutting element 8 are arranged in the exemplary embodiment in each case between the recesses 16.
    According to the invention, since the main cutting edges no longer have to be welded to the base cutting edge or the forceps, they can be made of a non-weldable material. This increases the service life and the strength and reduces the price.
    Due to the inventive screwing in the region of the support surface and advantageously the design of the support surface as a prism, the cutting parts are still connected in a manner which has a comparable strength with a welded joint.
    The forceps elements of the invention can be used in particular for forceps sizes with a gripping area between 1m2 and 5m2. Particularly advantageously, the pliers elements come as parts of wood tongs used.
    As a basic unit, for example, a hydraulic excavator can be used, on the boom of the pliers of the invention is attached.
    Due to the standardization of the shape of the basic cutting edge, one still obtains more identical parts, since for all pliers only one type of basic pliers has to be built as a basic variant. As a result, the production costs are reduced. In addition, the higher numbers of other production methods such. B. casting process profitable.
