One side of the limiting plate 36 is vertically and fixedly connected with a vertical plate 37; the end part of the vertical plate 37 is fixedly connected to one side of the limiting plate 36, after the end part of the cable pushes the support block 38 to move, a part of the limiting plate 36 is connected in the T-shaped groove 35 in a sliding mode, and the T-shaped groove 35 penetrates through the limiting plate 36 and the T-shaped groove 35 to facilitate the combination and the disassembly of the limiting plate 36 and the T-shaped groove 35.

The working principle is as follows: according to the invention, the cable is arranged between the two extrusion rods 4 to drive the electric push rod 3, the two extrusion rods 4 are close to each other and are extruded on the cable, and because the two opposite surfaces on the two extrusion rods 4 are concave, the cable is favorably and stably arranged between the extrusion rods 4 in the process of extruding the cable, and then the bent cable is extruded and straightened, at the moment, an operator can move and cut along a lead by using an art designer knife, and simultaneously the extrusion rods 4 are supported, so that the arm or hand of the operator can be erected on the extrusion rods 4, the stability of the arm and hand is ensured, the moving direction of the cutting of the art designer knife is ensured, and the peeling safety of the insulating layer at the end part of the cable is improved;

the upper surface of the cable is cut to draw a gap, then an art designer knife is used for radially cutting a circle along the cutting starting position on the cable, if a screwdriver is directly used for embedding into the gap, the gap is unfolded to take off the insulating layer, the edge of the cut gap is sharp, and the skin of an operator can be scratched, so that the pulling plate 5 is arranged, the pulling plate 5 is rotated, the other end of the pulling plate 5 is embedded into the gap, then the electric push rod 3 is started for resetting, in the resetting process, the output end of the electric push rod 3 pulls the extrusion rod 4, meanwhile, the pulling plate 5 pulls the gap to be unfolded, at the moment, the operator can embed the screwdriver into the unfolded port, and the smooth peeling of the insulating layer is facilitated;

when the utility knife is used for cutting the insulating layer, the effective cutting point of the utility knife is the front tip of the utility knife, the contact surface is small, the cutting trend of the utility knife on the cable is difficult to control, the end part of the utility knife possibly deviates from the axial direction of the cable, so that the cutting fails, and the insulating layer can be completely scratched by cutting for many times in the later period; the sliding block 7 is arranged, when cutting is carried out, the plate body 8 is pushed by hand, the sliding block 7 moves along the sliding groove 6, namely, the cutter 9 on the plate body 8 can stably move along the axial direction of the cable for cutting, and the insulating layer of the cable can be conveniently stripped;

the cable diameter has multiple specifications, when the cable diameter is larger, in the process of embedding the other end of the pulling plate 5 in the gap, because the opening size of the pulling plate 5 is a fixed value, the other end of the pulling plate 5 can be embedded in the gap a little, therefore, the movable pulling plate 5 is arranged, when the cable with larger diameter is peeled, the pulling plate 5 is rotated, the pulling plate 5 is pulled, the connecting block 11 pulls the spring and moves towards the extrusion rod 4, at the moment, the other end of the pulling plate 5 is gradually close to the cutting gap, then the other end of the pulling plate 5 is effectively embedded in the gap, the electric push rod 3 resets, the pulling plate 5 pulls the gap to open, and the insulating layer is taken down;

the other end of the pulling plate 5 is embedded into the gap, then the pulling plate 5 pulls the gap outwards, and meanwhile the salient points 13 are gradually embedded into the surface of the gap, so that the stability between the pulling plate 5 and the surface of the gap is improved, the possibility that the pulling plate 5 is separated from the gap when the pulling plate 5 pulls the gap is reduced, and the gap is ensured to be pulled and opened;

the diameters of the cables are different, so that after the two extrusion rods 4 extrude and fix the cables, the distances between the extrusion plates 25 are different and the same, and therefore, the gears 14 and the two groups of pull rods 15 are arranged, so that the plate bodies 8 can be erected on the extrusion rods 4 with different distances; according to the distance between the sliding grooves 6 on the two extrusion rods 4, one of the pull rods 15 in one group is pulled or pushed, under the meshing fit of the gear 14 and the rack 16, the other pull rod 15 in the other group moves along with the other pull rod, then the sliding block 7 is embedded into the sliding groove 6, and the cutter 9 on the plate body 8 is stably placed in the middle of the upper surface of the cable, so that a gap is smoothly cut on the cable in a sliding mode;

the diameters of the cables are different, the heights of the surfaces of the cables, protruding out of the surfaces of the extrusion rods 4, are different, the depth of the sliding blocks 7 embedded in the sliding grooves 6 is changed, when the plate body 8 moves, the plate body 8 swings left and right indefinitely, and meanwhile, the cutting edge of the cutter 9 swings left and right indefinitely, so that the moving smoothness of the plate body 8 is influenced, and the cutting of the cables is hindered; therefore, the cutter 9 is arranged to be movable up and down to adapt to cables with different diameters, in an initial state, the lower surface of the plate body 8 is higher than the upper surface of the cable, meanwhile, the sliding block 7 is also stably arranged in the sliding groove 6, and at the moment, the palm presses the arc-shaped plate 20 downwards and pushes the plate body 8 to move; the cutter 9 is pushed down by the arc-shaped plate 20, the cutter 9 cuts a gap on the surface of the cable, namely, the cutter 9 is pressed down according to the diameter of the cable and the thickness of the insulating layer, so that the plate body 8 can stably follow the extrusion rod 4, the stable cutting trend of the cutter 9 is ensured, and the smooth cutting of the cable is facilitated;

firstly, marking a cable, namely, stripping a mark of the length of an insulating layer, then inserting one end of the cable into the ring body 23 to enable the mark to be arranged at the position of the base block 29 and to be on the same surface with the blade 31 on the base block 29, then installing the screw 24, clamping the cable at the center of the ring body 23 in the center by the screw 24, driving the motor, driving the outer toothed ring 27 to rotate by the motor through the driving gear 28, driving the base block 29 to rotate by the outer toothed ring 27, simultaneously rotating the blade 31 around the cable, cutting a ring-shaped gap at a mark point on the surface of the cable, then loosening the screw 24, arranging the ring-shaped gap at one end of the extrusion rod 4, namely, the position on the plate body 8, which can be touched by the cutter 9, extruding the end of the cable by the extrusion rod 4, then moving the plate body 8, and cutting the cutter 9 on the plate body 8 to cut the gap along the ring shape; the blade 31 on the base block 29 is arranged, so that the radial cutting of the cable insulation layer is more convenient; the blade 31 is connected with the adjusting bolt 33 through the sliding plate 32, the adjusting bolt 33 is rotated, and the length of the blade 31 extending into the cavity is adjusted, so that the cable cutter is suitable for cables with different diameters and insulating layers with different thicknesses; and a guide plate 26 arranged outside the extrusion plate 25 facilitates the insertion of the end part of the cable into the ring body 23.
