    A dry shaving apparatus has a shearing foil, a reciprocable blade member cooperating with the shearing foil, a pressure spring urging the blade member toward the shearing foil and extending with the former in a first direction, a shearing head frame, and an auxiliary frame insertable into the shearing head frame and mounting the shearing foil so that it is convex. The auxiliary frame is fixed to the shearing foil at one longitudinal side of the former and is resiliently yieldable in the first direction. The auxiliary frame is arrested in the shearing head frame at the ends of the former.

    2. The electric shaver according to claim 1, wherein the lower part of the frame for the extra-net screen knife, parallel to the direction of movement of the inner knife, has a longitudinal slot covering the x-shaped bridges, whose height is equal to the stroke springs.
    3. Electric shaver on the PP. 1 and 2, characterized in that it is provided with at least one lining having openings with a flanged edge, the upper part of the frame for an external mesh knife on the outer surface has conical grooves and axles arranged therein entering into the apertures of the outer mesh knife and into the holes of the plate and rigidly connected with the flanged edges of the latter, and the lower part of the frame is made with an envelope flange on which the frame of the cutting head rests.
    4. Electric shaver on PP. 1 and 3, characterized in that the pad has L-shaped protrusions, and the lower part of the frame for the outer mesh knife is made with slots,
    in which are placed the l-shaped protrusions of the lining, the height of which is equal to the value of the spring stroke.
    5. Electric shaver according to claims 1-4, characterized in that the elements for fastening the frame for the external mesh knife are made in the form of elastic clamps with q hemispherical ends, and the frame of the head cutter has recesses on the inner front side
    in which hemispherical ends of clips are placed.
    6. Electric shaver on PP. 1-5, in contrast to the fact that the frame of the cutting head and the frame for the external mesh knife on the external end sides are made with transverse ribs.
    The invention relates to household appliances, in particular to electric razors. The closest to the technical essence and the achieved result is an electric razor, which contains the inner blade connected to the cutting head, which is modified in the mode of the cutting head, and the frame for an external mesh knife made of an elastic foil that has an opening in the frame at the peripheral part. and the spring D71 press the inner hole to the outer one. A disadvantage of the known construction is the possibility of damage to the outer mesh knife when bending, when cleaning due to the hard crepe of its to frame. The purpose of the invention is to increase reliability. This goal is achieved by the fact that in an electric razor containing an internal knife mounted in a cutting head frame, an inner knife connected to a drive, a frame made of an elastic material for an external mesh knife from a foil having holes in the frame in the peripheral part, and a spring for pressing the inner knife to outer frame for outer mesh knife at least on one side, parallel to the direction of movement of the inner knife, consists in height of two parts interconnected by means of x-shape spring-loaded jumpers, and elements for fastening this PEIMKH are placed on the end Sides of the frame of the cutting head. At the same time, the lower part of the frame for the outer mesh knife, parallel to the direction of movement of the inner knife, has a longitudinal slit that covers x-shaped bays, the height of which is equal to the spring travel. The shaver is equipped with at least one pad having openings with beading edge, the upper part of the frame for an external mesh knife on the outer surface has conical grooves and axles placed in them / entering the openings of the external mesh knife and holes of the plate and rigidly connected with the bead edges last , and the lower part of the frame is made with an envelope of the flange on which the frame of the cutting head rests. The lining can have L-shaped protrusions, and the lower part of the frame for the outer mesh knife is made with cuts, in COT01ShH there are L-shaped lugs of the lining, the height of which is equal to the spring travel. The elements for fixing the frame for the outer mesh knife are made in the form of elastic clamps with hemispherical ends, and the frame of the cutting head on the inner end side has recesses in which the hemispherical ends of the clamps are placed. In this case, the frame of the cutting head and the frame for the external mesh knife on the external, face sides are made with transverse ribs. FIG. Figures 1 and 2 show the electric ram; longitudinal sections in mutually perpendicular planes; in fig. 3 - cutting head, continuous section, in the zone of x-shaped bridges; in fig. 4 is the same longitudinal section in the fastening area of the lining; in fig. 5 - frame, view from the front side. The shaver includes a housing 1 mounted in a frame; 2 cutting heads are connected to a drive (not shown) inner knife 3, a frame 4 made of elastic material for an outer mesh knife 5 made of foil, having on its peripheral part 6 frame 4, and spring 7 for pressing the inner knife 3 to the outer knife The frame 4 for the outer mesh hole 5 on at least one side parallel to the direction of movement of the inner knife 3 consists of two parts 8 and 9 in height, interconnected by x-o spring bridges 10. The lower part 8 of the frame 4 has a slot 11 that covers x-shaped bridges 10 or slots 12, the height of the slots 11 and 12 determines the stroke of the spring 7. To attach the outer blade 5, the shaver can be equipped with at least one lining 13 having openings 14 with beaded edge 15 and L-shaped protrusions 16 placed in slots 12 of the lower part 8 of frame 4 for an external mesh knife. In order to fasten the mesh knife, the upper part 9 of the frame 4 on the outer surface has conical recesses 17 and is arranged therein. pins 18, which enter the holes 6, the diameter of which is at least the same size as the recesses 17, and the plates 14 in the holes 14 and rigidly connected to the beaded edges 15 of the plates 13, for example, by welding. Elements for securing pc1mki 4 for the outer mesh knife 5 are made in the form of elastic clamps 19 with hemispheric ends 20 and are located on the front sides of the cutting head, and the frame 2 of the cutting head has inner recesses 21 on the inner end side, in which the semi-aara ends 20 of the clamps 19 are located. part of the frame 4 for the outer mesh knife 5 is made with the flange 22, which is supported on the frame 2 of the cutting head, and the frame 2 and the frame 4 on the outer end sides are made with transverse ribs 23 n 24. The frame 4 is externally mesh knife 5 at least on one side parallel to the direction of movement of the inner knife 3, of two parts 8 and 9, interconnected by means of x-shaped jumpers 10, together with n: 1, 7, provides for the springing of the outer mesh knife 5 when shaving, prep However, some movement of the cutting foil of the external knife in the direction of the reciprocating movement of the internal knife 3. The elements for fixing the frame for the external screen knife in the form of elastic clamps with hemispherical ends, and p pits cutting head with the inner face side with recesses in which clips are arranged hemispherical ends, poz-; It is possible to avoid any mechanical stresses on the external mesh knife when installing or removing the frame with the external blade, and, consequently, damage to the cutting foil of the external mesh knife, which increases the strength of the electric shaver.
