    The invention relates to the production of Biire .nt-Nomu production and can be used when cutting pipes for 3 e. Preparations. From the chain chain kick,; win; and pulling device, interchangeable tststg and ttgzorotnye leverage, to; from which one shoulder is associated with the tensioning device, and the free shoulder from one lei of leverage is made in the form of a cru-rifle i-eziOCTa-ka tek A pipe cutter is more labor intensive when replacing a chain. The purpose of the invention: and - increase in the chain replacement by ,, means. This goal is achieved by the fact that in a chain cutter containing a tension device, a changeable chain and porsy two-arm levers, each of the CLiHTjn; , and free p / yucho of one of the levers.: HtHO in the form of a hook, grip free G1.: another lever is also:: -nol In the form of a hook, and a tension device - in the form of a grinder with a bracket, a ram on the rod and sub-ram: UHeHHOftd with respect to the bracket, and the shank under the arm fabric with a profile outer surface, installed on the rod by means of Doro threads (With a line of interaction; interaction; its face and a slider with oc: - f turning, two shoulders mounted in a bracket, and levers connected with tensioning device by means of connecting rods. On the ii-u, 1 a pipe cutter is shown, obtitsii VID; fig, 2 - the same, bochm by / head (; ene ;, in fig. 4, a handle of the pipe cutter; fig. 5 1.fire for CsRi vra de -1ie; in fig. b the same .ll pe: iK} 5 head Fig. 7 - the same, the length of the clip -pipes. Chain Tube: contains cypdra ster "(; nh 1 with thread 2, connected to kroniggeyn 3, equipped with a cylindrical bore 4. in which the end of the rod 1 is pressed, pin 5, passage through: kr0; vltayn 3 and rod. 1, and thus joining them together, on both sides of the rod axis and perpendicular to this axis, bracket 3 contains two decorators, in FcoTopHX, the axis 7 is fixedly pressed on, rod 8 is mounted on rod 1 , interacting with the 1G with: 1 drill hole 9, which positions it freely to slide along the rod 1. On both sides of the axis of the slit The rotates can rotate and move relative to the slider 8. On the upper surface 12 of the slider 8, there is a cylindrical protrusion 13, concentric with the axis of the rod 1. The cylindrical shank 14 is provided at the lower end with an opening 15 with an internal thread 16 that interacts with the thread 2 of the rod 1. Surface 17, the drill interacts with the slider HEAD 13 and provides the centering of the slider relative to the quastovik 14. The compression spring 18 is mounted on the rod 1 and, accordingly, rests on the upper surface with its ends 19 of the bracket 3 and on the surface 20 of the groove 21 extending onto the bottom surface 22 of the slide. The bore 21 has a sufficient length to accommodate the spring 18 in a compressed state and to bring the surfaces 19 and 22 into contact. On axis 7, four levers 23 are hinged on the outside and on both sides of the brackets 3; at the same time there are two levers for each axis of the spout. On each lever is the end of its shoulder, directed upwards / there is a cylindrical bore 24 and which is mounted on the chat’s axis 25, interconnecting two levers located on one side of the bracket 3, on the axis 25 and one; A rotary connecting rod 26 is installed, equipped with an opening 27, interacting. with axis 11, on which it is free to rotate. In combination, the tensioning device is a deformable system, and when screwing in the shank 14, it pushes the slider 8, which lowers along the rod 1. The levers are pivotally mounted on fixed axles x 7 relative to the rods. turns; under the action of the force transmitted by the connecting rods 26. Bracket 3 and the central part contains; Ledge part 28, is symmetrically mounted on the axis of the rod 1 and on which the levers 23 are supported, located on both sides of the axis of the rod 1, when the tensioning device is maximally opened; those. when the shank 14 is unscrewed, so that the B line of the hinge joints of the immobilized device does not take place and, J (on the other hand, blocking this deformable system, which would prevent tightening of the tension device), the outer part of the shank 14 consists of two parts The cylindrical spring of this upper part has a smaller diameter than the lower one, which is filled with four tides 29,
    located through 90 ° relative to the axis of the shank, forming a cross around the top. These tides serve to turn the shank into rotation when the cutting chain is compressed on the pipe being cut. A pipe cutter can be manipulated with the aid of a handle 30, equipped with a rod 31 and having four sockets 32 in the lower part, arranged through 90 °, reproducing the profile of tides 29 and cooperating with them to provide a connection in rotation of the tensioning device and handle 30. A lever 33 containing the ratchet 34 with latches 35 located 90 and cooperating with the handle tides 29 and the lever 36 intended for rotation and located perpendicular to the axis of the ratchet is also foreseen. In the upper part of the ratchet 34, there are two tides 36, arranged through 180 °, intended to interact with the tides 29 in order to unclench the pipe cutter, which cannot be done with the help of the ratchet 34.
    This pipe cutter can be equipped with various chains: for cutting by pressure, rotation or compression,
    Cutting chain
    FIG. 5) consists of pivotally connected links, turning cix on axes 37 and detached by incisors. In this chain, the ends 38 of the axis 37 and the nuts 39 protrude much on each side of the chain and serve to engage. The lower ends of the levers 23 are made in the form of a hook hook 40 and provide for the engagement of the chain along any axis so that it is possible to adjust the length of the chain as desired.
    The pressure-cutting chain (FIG. B) consists of very short links 41 connected by axes 42, in steps stepping on both sides of the links, and each of which has a cutter 43, which also provides for cross-linking of the links. The length of the links is such that the incisors are located almost tangentially. The two links at the ends have (each), an end axis 44 of sufficient length and diameter to allow the chain to engage in the grippers of the levers 23 of the tensioning device, and the spacer washers 45 provide a possible adjustment of the position of the chains in these grips. Other washers 46 keep the links at a distance on both sides of the tool. In order to adjust the chain in length, which cannot be produced as for cutting by rotation, since only the axes of the final links are provided for engagement with the tension device, axis 47, located as close as possible to one end of the chain, has two washers 46, installed pivotally on this axis on each side of the chain. By installing these washers on any axis 42, you can close a certain number of links and, therefore, choose the useful chain length necessary to cut a pipe of a certain diameter.
    The pipe clamping chain (.fig. 7) consists of the same links 41 and axes 42 as the cutting chain. But the same length adjustment device by reducing the circuit by closing the links using ratchets 46. Thus, the device can be used as a pipe wrench, which is very necessary when it is necessary to fix the pipe in rotation.
    Truborez works as follows.
    A: Depending on the nature of the pipe; a pipe cutter is equipped with a suitable chain: for cast iron or steel, a cutting chain for cutting by rotation, for fiber cement, concrete or ceramics by a chain for cutting with pressure, for fixing a pipe made of any material in rotation, by a chain with a clamp. The required chain length is set, then the operator actuates the tensioning device with the lever 33 with a ratchet or handle 30. The deformable hinge system forming the tensioning device transfers the clamping force produced by the operator to the cutting chain with increased clamping force with a reciprocating rotation, the cutter cuts into the pipe and cuts it.
    Compared with the base object, the invention improves the convenience of chain replacement.
