The back of a knife blade 1 is fixedly connected with a steering rod 2, the steering rod 2 is inserted into the through hole, and the steering rod 2 can rotate in the through hole. The blade 1 is detachably connected with the tool path base 3.

The blade 1 and the tool path base 3 are detachably connected, and the steering rod 2 fixedly connected with the blade 1 can rotate in the through hole of the tool path base 3, so that when a cable is cut, the direction of the blade 1 can be adjusted according to the size and the thickness of the cable, and a proper cutting mode can be selected. The cutting mode includes a slitting mode, a crosscutting mode, and a beveling mode. In the longitudinal cutting mode, the blade 1 is perpendicular to the cable, and the wire stripper is rotated along the circumferential direction of the cable, so that the cable sheet is cut in a circumferential mode. In the transverse cutting mode, the blade 1 is parallel to the cable, which is cut into a grid. In the beveling mode, the blade 1 is obliquely arranged with the cable, and the cable is cut in a spiral shape by rotating the wire stripper.

For thicker cable sheets, a mix of transverse and longitudinal cuts can be chosen: the steering rod 2 is firstly rotated to enable the blade 1 to be parallel to the cable, after the blade 1 is locked on the tool rail base 3 after the blade is rotated to the proper position, and then the cable is transversely cut along the length direction of the cable. The wire stripper is then rotated to transect the cable in the next position. After the transverse cutting is finished, the locking between the blade 1 and the tool rail base 3 is released, then the steering rod 2 is rotated to enable the blade 1 to be perpendicular to the cable, after the blade 1 is rotated in place, the blade 1 is locked on the tool rail base 3, and then the wire stripper is rotated along the circumferential direction of the tail end of the cable sheath to be cut, so that the longitudinal cutting is finished. Thus, a plurality of axial cracks and a circle of circumferential cracks are formed on the cable sheath to be cut. The cable sheath can be pulled off piece by piece along the crack when the cable sheath is pulled. Compared with a mode of pulling the whole cable piece down in a longitudinal cutting mode, the mode of pulling the cable sheath piece by piece can obviously reduce the labor consumption, improve the operation efficiency and reduce the operation risk.

The principle of the beveling mode is the same as that of apple peeling, the cable sheath can be cut in a spiral mode, the operation is similar to that of the longitudinal cutting mode, and the description is omitted.

In the utility model, the cutting mode can be selected according to the size and the thickness of the cable, and can be one mode of a longitudinal cutting mode, a transverse cutting mode and a beveling mode, or any two or three mixed modes, and the aim is to enable operators to pull the cable sheath easily, reduce the labor consumption, improve the working efficiency and reduce the working risk.

Regarding the detachable connection of the blade 1 to the guide rail base, this can be achieved by means of a screw connection. The utility model provides a special detachable connection mode: the utility model is provided with a clamping cylinder 104 at one side of the tool path base 3 close to the blade 1, and the clamping cylinder 104 is arranged coaxially with the steering rod 2. The card cylinder 104 is provided with a card slot 11, and the card slot 11 extends along the axial direction of the card cylinder 104. The clamping groove 11 is of an open structure at one end far away from the tool rail base 3, and an opening is formed in the clamping groove 11, and the opening is used for allowing the back of the blade 1 to enter. The pockets 11 are provided in pairs, and each pair of pockets 11 is arranged symmetrically with respect to the steering column 2. The back of the blade 1 is simultaneously clamped in the two clamping grooves 11. The card cylinder 104 is provided with a plurality of pairs of card slots 11. When the blade 1 is clamped in different pairs of clamping grooves 11, the angle formed by the blade 1 and the cable is different, so that the blade 1 can be in a longitudinal cutting mode, a transverse cutting mode and a beveling mode respectively.

The steering rod 2 projects from the side of the tool path base 3 remote from the blade 1, on which side an abutment is connected to the steering rod 2 and on which side a spring 5 is fitted over the steering rod 2. One end of the spring 5 is abutted against the abutting piece, and the other end is abutted against the tool path base 3. The spring 5 forms the thrust of keeping away from tool path base 3 to the butt joint piece, and the butt joint piece is connected with steering column 2, and the butt joint piece can form the pulling force to steering column 2 so, and steering column 2 is connected with blade 1 again, therefore blade 1 can be strained in the bottom of draw-in groove 11 to make the back of a knife blade of blade 1 support tightly in the bottom of draw-in groove 11. This axially locks the steering rod 2. The back of a knife blade 1 is located a pair of draw-in grooves 11, and the inside wall of draw-in groove 11 has also formed spacing to blade 1 to prevent blade 1 from taking place circumferential direction. Since the blade 1 is subjected to the axial and circumferential restrictions, the blade 1 can perform stable cutting.

If blade 1 is to be reversed, blade 1 is simply pushed out of pocket 11 against the spring force of spring 5, then turning the steering lever 2 to rotate blade 1 to the proper orientation and ensure that the back of blade 1 is aligned with the pair of pockets 11 matching that orientation, then releasing spring 5, and blade 1 is pulled tight to the bottom of pocket 11 by the spring force of spring 5. In the utility model, the blade 1 is reversed only by pushing the steering rod 2 and rotating the rotating rod, and the reversing operation is very simple.

In order to realize the longitudinal cutting mode, the transverse cutting mode and the oblique cutting mode, the card slot 11 on the card cylinder 104 at least comprises three pairs. A pair of card slots 11 are parallel to the cable to achieve the cross-cut mode of the blade 1. The other pair of pockets 11 is perpendicular to the cable to achieve a rip cut pattern of the blade 1. A third pair of card slots 11 is arranged diagonally to the cable to achieve a bevelling pattern of the blade 1.
