The circumferential cutting and chamfering device for the main insulation layer of the cable includes: a chamfering frame and a circumferential cutting and chamfering assembly. The chamfering frame includes a holding portion 11 and an arc-shaped hook structure 12 provided at one end of the holding portion 11. The circumferential cutting and chamfering assembly includes a base 21, a tool holder 22, and a blade 23. The base 21 is slidably disposed on the holding portion 11 to approach or move away from the hook structure 12. The tool holder 22 is rotatably disposed on the base 21 and is located on one side of the base 21 facing the mouth of the hook structure 12. The blade 23 is disposed on the tool holder 22;

[0035] Wherein, when the tool holder 22 rotates, it has a circumferential cutting state in which the blade 23 circumferentially cuts the main insulation layer of the cable and a chamfering state in which the blade 23 obliquely cuts the main insulation layer of the cable.

[0036] In this embodiment, the circumferential cutting and chamfering device for the main insulation layer of the cable includes a chamfering frame and a circumferential cutting and chamfering assembly. The chamfering frame includes a holding portion 11 and an arc-shaped hook structure 12 provided at one end of the holding portion 11. During use, the cable is passed through the hook structure 12, and by holding the holding portion 11 by hand, the circumferential cutting and chamfering device for the main insulation layer of the cable is rotated circumferentially around the cable. During the rotation, the main insulation layer of the cable is chamfered or circumferentially cut by the blade 23. Specifically, the circumferential cutting and chamfering assembly includes a base 21, a tool holder 22, and a blade 23. Since the tool holder 22 is rotatably disposed on the base 21, and the tool holder 22 is located on one side of the base 21 facing the mouth of the hook structure 12, and the blade 23 is disposed on the tool holder 22, and the base 21 is slidably disposed on the holding portion 11, when the base 21 slides close to or away from the hook structure 12, the position of the blade 23 can be adjusted, so that the circumferential cutting and chamfering device for the main insulation layer of the cable can chamfer or circumferentially cut cables with different diameters;

[0037] When the tool holder 22 of this embodiment rotates, it has a circumferential cutting state in which the blade 23 circumferentially cuts the main insulation layer of the cable and a chamfering state in which the blade 23 obliquely cuts the main insulation layer of the cable. During use, when the main insulation layer of the cable needs to be circumferentially cut, the tool holder 22 is rotated to the circumferential cutting state. When the main insulation layer of the cable needs to be chamfered, the tool holder 22 is rotated to the chamfering state. It can be seen that the circumferential cutting and chamfering device for the main insulation layer of the cable in this embodiment can achieve chamfering and circumferential cutting of the main insulation layer of the cable by rotating the tool holder 22, improving the use range and convenience of the device. The circumferential cutting and chamfering are completed on the same device, greatly reducing the clamping time and improving the operation efficiency.

[0038] In some embodiments, when in the circumferential cutting state, the blade 23 is perpendicular to the axis of the cable, and at this time, the main insulation layer of the cable can be circumferentially cut by the blade 23; when in the chamfering state, the blade 23 forms an angle of 45° with the axis of the cable, and at this time, the main insulation layer of the cable can be chamfered by the blade 23.

[0039] In this embodiment, the blade 23 forms other angles with the axis of the cable, which can increase the applicable range of the circumferential cutting and chamfering device for the main insulation layer of the cable, so as to meet various different needs of customers.

[0040] The blade 23 can be locked to the tool holder 22 through locking parts such as screws.

[0041] In some embodiments, one side of the holding portion 11 facing the mouth of the hook-shaped structure 12 has a first guiding groove 111 extending from the end far away from the hook-shaped structure 12 to the end facing the hook-shaped structure 12. The base 21 is slidably arranged in the first guiding groove 111. The circumferential cutting and chamfering device for the main insulation layer of the cable further includes a rotary driving rod 3 and a supporting plate 4.

The rotary driving rod 3 is rotatably inserted into the supporting plate 4, and one end of the rotary driving rod 3 is rotatably connected to the base 21. When rotating the rotary driving rod 3, the rotary driving rod 3 uses the supporting plate 4 as a fulcrum, and then drives the base 21 to approach or move away from the hook-shaped structure 12. Specifically, the rotary driving rod 3 is a lead screw, and a threaded hole is formed in the supporting plate 4. The rotary driving rod 3 is in internal and external thread fit with the threaded hole to realize driving the base 21 to approach or move away from the hook-shaped structure 12 when rotating the rotary driving rod 3.

In this embodiment, by slidably disposing the sliding seat 5 on one side of the base 21 facing the mouth of the hook-shaped structure 12, the sliding seat 5 can approach or depart from the hook-shaped structure 12 when sliding, further increasing the adjustment range of the cable main insulation layer circumferential cutting and chamfering device.

[0046] In some embodiments, second guiding grooves 211 consistent with the moving direction of the base 21 are formed on two opposite side walls of the base 21. The sliding seat 5 is formed with extending portions 51 respectively located on both sides of the two second guiding grooves 211. On one side where the two extending portions 51 face each other and approach, sliding matching portions 52 respectively inserted into the two second guiding grooves 211 are formed.
