[0002] Cable strippers are essential tools for electrical engineers, electronics engineers, and communications technicians. They are used to strip the insulation of wires or cables to expose the internal conductors for connection, testing, or repair.

[0003] With the continuous development of my country's power industry, there are more and more places where live-line work is needed, and the requirements for live-line work are also constantly increasing. However, live-line connection work is a high-altitude operation with a very harsh environment. Moreover, the work object is high voltage. Under the premise of ensuring safety, if workers use traditional wire strippers to strip the wire, it is easy to cause the blade to penetrate too deeply and damage the wire core. Utility Model Content

[0004] The purpose of this utility model is to provide a wire stripper for high-altitude live-line work, which aims to solve the problem that traditional wire strippers in the prior art cannot strip wires and are prone to excessive cutting depth, causing damage to the wire core.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire stripper for live-line work at height includes an insulating box, a cutting section located at the end of the insulating box, which covers the outside of the cable and can cut the outer protective layer of the wire core when it moves; and a control section located at the end of the insulating box away from the cutting section, used to control the depth of the cable insertion into the insulating box and the cutting section, thereby controlling the length of the cut on the protective layer. The cutting section includes a first semi-circular ring and a second semi-circular ring located at the end of the insulating box, into which the cable can be inserted. The end of the first semi-circular ring near the insulating box is fixedly connected to the insulating box, and the end of the second semi-circular ring near the insulating box is hinged to the insulating box. Both the first and second semi-circular rings have through slots that are symmetrical. Each through slot has a cutting blade, and the end of the cutting blade away from the insulating box is rotatably connected to the through slot. The end of the cutting blade near the insulating box can be adjusted up and down.

[0007] A further technical solution of this utility model is that both the first semicircular ring and the second semicircular ring are provided with adjustment parts for adjusting the end of the cutting blade that is close to the insulating box.

[0008] A further technical solution of this utility model is that the adjustment part includes a slide plate that is slidably connected to the arc surfaces of the first semicircular ring and the second semicircular ring. A threaded rod is threadedly connected to the slide plate. A connecting plate is rotatably connected to the end of the threaded rod near the cutting blade, and the end of the connecting plate near the cutting blade is hinged to the cutting blade.

[0009] A further technical solution of this utility model is that the control unit includes a baffle that is slidably connected inside the insulation box. A lead screw is rotatably connected to one side of the baffle away from the first semicircular ring and the second semicircular ring. The end of the lead screw away from the baffle extends to the outside of the insulation box. The lead screw is threadedly connected to the insulation box. A handle is fixedly connected to the end of the lead screw away from the baffle.

[0010] A further technical solution of this utility model is that through holes are provided on the side of the first semicircular ring and the second semicircular ring that are close to each other, and the cable can be inserted into the through holes.

[0011] A further technical solution of this utility model is that a limiting ring is sleeved on the surface of the insulating box, and the limiting ring can move along the insulating box to limit the second semi-circular ring.

[0012] The beneficial effects of this utility model are:

[0013] The cable is inserted into the first and second semicircular rings. The tilt angle of the cutting blade is adjusted by the adjustment part according to the different thicknesses of the wire core protective layer. The cable end is inserted into the first and second semicircular rings from the end away from the insulating box. The insulating box pushes the first and second semicircular rings to move along the cable. When the first and second semicircular rings move, they can drive the cutting blade to move, so that the cutting blade can cut the wire core protective layer. This allows for the stripping of cables with different thicknesses of protective layer, effectively avoiding damage to the wire core by the cutting blade and improving the safety of cutting.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1 and Figure 2 As shown, a wire stripper for high-altitude live-line work includes an insulating box 1. A cutting section is provided at the end of the insulating box 1, which can cover the outside of the cable. The worker can push the insulating box 1 and the cutting section to move along the cable axis. When the cutting section moves, it can cut the outer protective layer of the wire core. A control section is provided at the end of the insulating box 1 away from the cutting section to control the depth of the cable insertion into the insulating box 1 and the cutting section, thereby controlling the length of the cut on the protective layer. In summary, it can easily peel off the outer protective layer of the wire core, effectively preventing damage to the wire core by the cutting blade 24 and improving cutting safety. The cutting section includes a first semi-circular ring 21 and a second semi-circular ring 22 provided at the end of the insulating box 1. The first semi-circular ring 21 and the second semi-circular ring 22 are hollow semi-circular rings, allowing the cable to be inserted into the interior of the first semi-circular ring 21 and the second semi-circular ring 22. The end of the first semi-circular ring 21 closest to the insulating box 1 is fixedly connected to the insulating box 1. Next, the end of the second semicircular ring 22 closest to the insulating box 1 is hinged to the insulating box 1. Both the first semicircular ring 21 and the second semicircular ring 22 have through slots 23, and the two through slots 23 are symmetrical. Both through slots 23 are provided with cutting blades 24, and the end of the cutting blade 24 away from the insulating box 1 is rotatably connected to the through slot 23. The end of the cutting blade 24 closest to the insulating box 1 can be adjusted up and down. By adjusting the tilt angle of the cutting blade 24, the cutting depth of the cutting blade 24 on the wire core protective layer can be controlled. First, the cutting blade 24 is adjusted according to the thickness of the wire core protective layer. Then, the cable is inserted into the first semicircular ring 21 and the second semicircular ring 22 from the end away from the insulating box 1. Then, the insulating box 1 pushes the first semicircular ring 21 and the second semicircular ring 22 to move along the cable, so that the cutting blade 24 can cut the protective layer during the movement, and thus can strip cables with protective layers of different thicknesses.

[0019] like Figure 1 and Figure 2 As shown, both the first semicircular ring 21 and the second semicircular ring 22 are provided with adjustment parts for adjusting the end of the cutting blade 24 near the insulating box 1, so that the tilt angle of the cutting blade 24 can be easily adjusted to cut protective layers of different thicknesses.

[0020] The adjustment unit includes a slide plate 31 that is slidably connected to the arc surfaces of the first semicircular ring 21 and the second semicircular ring 22. A threaded rod 32 is threadedly connected to the slide plate 31. A connecting plate 33 is rotatably connected to one end of the threaded rod 32 near the cutting blade 24. The end of the connecting plate 33 near the cutting blade 24 is hinged to the cutting blade 24. By driving the threaded rod 32 to rotate and pushing the slide plate 31 to translate, the cutting blade 24 can be pushed to move toward the cable, thereby enabling cutting of cables with different thicknesses of protective layers.

[0021] like Figure 1 As shown, the control unit includes a baffle 41 slidably connected inside the insulation box 1. A lead screw 42 is rotatably connected to one side of the baffle 41 away from the first semicircular ring 21 and the second semicircular ring 22. The end of the lead screw 42 away from the baffle 41 extends to the outside of the insulation box 1. The lead screw 42 is threadedly connected to the insulation box 1. A handle 43 is fixedly connected to the end of the lead screw 42 away from the baffle 41. The worker can rotate the handle 43 to drive the lead screw 42 to rotate. The rotation of the lead screw 42 can push the baffle 41 to move horizontally. By adjusting the position of the baffle 41, the length of the cable inserted into the first semicircular ring 21 and the second semicircular ring 22 can be controlled. In this way, the length of the cutting blade 24 cutting the wire core protective layer can be easily controlled.

[0022] As shown in Figure 2, the first semicircular ring 21 and the second semicircular ring 22 are both provided with through holes 5 on their adjacent sides. The cable can be inserted into the through holes 5. By pushing the first semicircular ring 21 and the second semicircular ring 22 to rotate around the circumference of the cable, the cutting blade 24 can perform a circumferential cut on the cable, thereby enabling multi-directional cutting of the core protective layer.

[0023] like Figure 1 and Figure 2 As shown, a limiting ring 6 is fitted on the surface of the insulating box 1. The limiting ring 6 can move along the insulating box 1 to limit the second semicircular ring 22. When the limiting ring 6 moves to contact the insulating box 1 and the second semicircular ring 22 at the same time, the limiting ring 6 can limit the second semicircular ring 22, so that the two cutting blades 24 can cut the cable at the same time. When the limiting ring 6 does not limit the second semicircular ring 22, the cutting blade 24 on the first semicircular ring 21 can cut the cable, so that the cutting blade 24 can perform circumferential cutting on the cable according to the actual use.

[0024] Working principle: First, the cable is inserted into the first semicircular ring 21 and the second semicircular ring 22. Then, the tilt angle of the cutting blade 24 is adjusted by the adjustment part according to the different thicknesses of the wire core protective layer. Next, the cable end is inserted into the first semicircular ring 21 and the second semicircular ring 22 from the end away from the insulating box 1. Then, the insulating box 1 pushes the first semicircular ring 21 and the second semicircular ring 22 to move along the cable. When the first semicircular ring 21 and the second semicircular ring 22 move, they can drive the cutting blade 24 to move, so that the cutting blade 24 can cut the wire core protective layer. This allows for the stripping of cables with different thicknesses of protective layers, effectively avoiding damage to the wire core by the cutting blade 24 and improving the safety of cutting.
