The output shaft of the motor four 12 is connected with a bidirectional screw 20. The bidirectional screw 20 is respectively in threaded connection with the upper clamp 10 and the lower clamp 11. A cable positioning groove is formed in each of opposite surfaces of the upper clamp 10 and the lower clamp 11, a cable penetrating between the upper clamp and the lower clamp is positioned through the two cable positioning grooves, and the upper clamp and the lower clamp can still rotate around the cable. The upper section and the lower section of the bidirectional screw 20 are provided with external threads in opposite directions. The upper clamp 10 and the lower clamp 11 are respectively provided with a screw connecting hole with an internal thread, and the internal thread directions of the screw connecting holes on the upper clamp 10 and the lower clamp 11 are the same. The bidirectional screw 20 sequentially passes through screw connecting holes on the upper clamp 10 and the lower clamp 11. Two sides of the bidirectional screw 20 are respectively provided with a guide post I21, and the guide posts I21 play a role in guiding, so that the stability of the upper clamp and the lower clamp along the movement direction of the bidirectional screw and the movement process is ensured.

The cable positioning mechanism is mounted on one side of the split gear 8. The opening gear 8 is fixedly connected with a bracket 9. As shown in fig. 6, the transmission gear set includes a driving gear 14 connected to the output shaft of the first motor 7 and two transmission gears 15 symmetrically disposed at both sides of the driving gear 14. The first motor works to drive the driving gear 14 to rotate, the driving gear drives the two transmission gears 15 which are meshed and connected with the driving gear to rotate, and the two transmission gears 15 drive the opening gear 8 which is meshed and connected with the driving gear to rotate. Because the bracket 9 is fixedly connected with the shedding gear 8, when the shedding gear 8 rotates, the bracket, the cable positioning mechanism and the peeling tool which are arranged on the bracket rotate around the cable together with the bracket, so that the peeling tool can perform circular cutting on the cable. The arc length between the meshing points of the two transmission gears 15 and the shedding gear 8 is larger than the opening arc length of the shedding gear 8, so that when the opening side of the shedding gear 8 rotates to the meshing side with the transmission gears 15, one transmission gear 15 is certainly in transmission meshing with the shedding gear 8. The opening of the opening gear 8 at the initial position faces horizontally outwards, so that the wire hanging operation is convenient.

The mounting panel is installed to slip table 4 top, and transmission case 6 is installed on the mounting panel. When the second motor 2 works, the screw rod 3 rotates to drive the sliding table 4 in threaded fit with the screw rod 3 to linearly move along the axial direction of the screw rod 3, so that the peeling cutter with the adjustable feed angle, the cable positioning mechanism and the cutter rotary driving mechanism are driven to linearly move along with the cable. Therefore, on the basis that the cable is subjected to circular cutting by the peeling cutter, the circular cutting with continuous length is realized, and the continuous automatic peeling of the cable is realized.

When the cutting angle of the tool 13 is adjusted, the tool 13 can be swung around the cutting edge. The tool point of the tool is the circle center, so that the position of the cutting point of the tool cannot be changed. After the feed angle of the tool 13 is adjusted, the tool holder 16 is fixed by a fastening screw 18, which fastening screw 18 is screwed through the arc-shaped through slot into a corresponding threaded hole in the upper clamp 10. The installation mode has double-arc guiding and positioning, can ensure that the cutting point of the cutter 13 before and after adjustment can not deviate, and is stable and reliable.
