The base 11 is provided with an avoidance groove 111 having the same shape as the opening 121. Before hanging on the cable, the opening 121 and the avoidance groove 111 are aligned for easy wire hanging. After hanging, the rotating seat 12 rotates around the base 11 with the axis of the semicircle as the rotation axis;

After the two clamping plates 21 approach each other, the cable can be clamped in the two V-shaped grooves 211 so that the clamping plate 21 will not slip, and the clamping plate 21 can slide along the cable.

[0045] The cutter 3 is installed on the wire clamping assembly 2, and the axis of the cutter 3 has an adjustable angle with a reference plane, and the reference plane is perpendicular to the rotation axis of the rotating seat 12;

[0046] The handle 4 is connected to the base 11. The angle between the handle 4 and the base 11 can be adjusted. After the opening 121 is clamped on the cable, the angle between the handle 4 and the base 11 is fixed and connected and fixed.

[0047] The cable stripper is provided with a battery for powering all the electrical devices of the cable stripper.

[0048] For the cable stripper proposed in this embodiment, the opening 121 is sleeved on the cable through the hand-held handle 4, and the two clamping plates 21 approach each other to clamp the cable therebetween and can slide on the cable. During the process of the rotary seat 12 rotating relative to the base 11, the tool 3 cuts the insulating skin of the cable. The axis of the tool 3 has an adjustable angle with the reference plane, so that the tool 3 slides along the cable while cutting, thereby realizing the stripping of a longer cable. The stripping process is automatically completed, which can improve the stripping efficiency and can realize live working without affecting the efficiency of power construction.

[0049] In some embodiments, the angle between the axis of the tool 3 and the reference plane is 5 degrees. By setting the angle between the axis of the tool 3 and the reference plane to 5 degrees, the tool 3 has a cutting force along the axial direction of the cable while rotating, spirally cuts the insulating skin, and drives the whole device to move along the cable. The 5-degree angle makes the cutting resistance smaller on the premise that the device can move, which is beneficial to the device cutting the insulating skin and improves the reliability and stability of the device.

[0050] In some embodiments, the rotating assembly 1 further includes a first transmission mechanism 13 and a first driving device 14; the first transmission mechanism 13 is respectively connected to the base 11 and the rotary seat 12 to drive the rotary seat 12 to rotate around the base 11; the first driving device 14 is installed on the rotary seat 12 and is drivingly connected to the first transmission mechanism 13. The first driving device 14 drives the first transmission mechanism 13 to move, thereby driving the rotary seat 12 to rotate around the base 11 to realize the circumferential cutting of the insulating skin of the cable.

[0051] In some embodiments, the first transmission mechanism 13 includes an internal gear 131 and a first external gear 132. The internal gear 131 is arranged on the base 11. The first external gear 132 is rotatably installed on the rotary seat 12 and is connected to the first driving device 14. The first external gear 132 meshes with the internal gear 131 for transmission. By the first transmission mechanism 13 including the internal gear 131 and the first external gear 132, the internal gear 131 is arranged on the base 11, the first external gear 132 is rotatably installed on the rotary seat 12 and is connected to the first driving device 14, and the first external gear 132 meshes with the internal gear 131 for transmission. The first driving device 14 drives the first external gear 132 to rotate. The external gear meshes with the internal gear 131, and the base 11 does not move, so that the first external gear 132 makes a circular motion along the teeth of the internal gear 131, thereby driving the rotary seat 12 to rotate around the base 11. The first driving device 14 can adopt a motor. In actual design, the internal gear 131 and the base 11 can be integrally formed.

[0052] In some embodiments, the first transmission mechanism 13 further includes a second external gear 133, which is rotatably installed on the rotating base 12 and meshes with the first external gear 132 and the internal gear 131 respectively. Specifically, there are two second external gears 133, which are respectively meshed on the upper and lower sides of the first external gear 132 and both mesh with the internal gear 131. The distance between the meshing points of the two second external gears 133 and the internal gear 131 is greater than the width of the opening 121, so as to avoid the cables at the opening 121, prevent interference with the cables and affect the rotation and movement of the device. Moreover, through the transfer of the second external gear 133, the transmission becomes more stable, improving the reliability and stability of the device.

[0053] In some embodiments, the rotating base 12 includes two rotating plates 122 that are spaced apart and connected to each other. The two rotating plates 122 are rotatably installed on both sides of the base 11, and are respectively connected to the first driving device 14 and the wire clamping assembly 2. By rotatably installing the two rotating plates 122 on both sides of the base 11 and respectively connecting the two rotating plates 122 to the first driving device 14 and the wire clamping assembly 2, the first driving device 14 and the wire clamping assembly 2 are respectively installed on both sides of the base 11, avoiding placing them on one side, which would make the structure relatively large, making the structure more compact and small. Moreover, it can balance the weights on both sides of the base 11, prevent one side of the base 11 from being too heavy and causing the device to drop downward to one side, and improve the reliability and stability of the device.

[0054] In some embodiments, annular grooves 112 are respectively provided on two end faces of the base 11, and arc-shaped convex blocks 123 are provided on the rotating plates 122. The arc-shaped convex blocks 123 are rotatably installed in the annular grooves 112. By respectively providing the annular grooves 112 on two end faces of the base 11, providing the arc-shaped convex blocks 123 on the rotating plates 122, and rotatably installing the arc-shaped convex blocks 123 in the annular grooves 112, the arc-shaped convex blocks 123 slide along the annular grooves 112, thereby realizing the rotational connection between the rotating plates 122 and the base 11 and guiding the rotation of the rotating plates 122 at the same time.

[0055] In some other embodiments, the positions of the annular grooves 112 and the arc-shaped convex blocks 123 can be interchanged.

[0056] In some embodiments, the wire clamping assembly 2 further includes a wire clamping frame 22, a second transmission mechanism 23 and a second driving device 24 mounted on the wire clamping frame 22; the second transmission mechanism 23 is connected to the two clamping plates 21 and is drivingly connected to the second driving device 24 to drive the two clamping plates 21 to approach or separate from each other under the drive of the second driving device 24. The cutter 3 is mounted on the wire clamping frame 22. By driving the second transmission mechanism 23 by the second driving device 24, the two clamping plates 21 are driven to approach or separate from each other, so as to realize the sleeving or removal of the device on the cable.

[0057] In some embodiments, the second transmission mechanism 23 includes a bidirectional lead screw 231, two lead screw seats 232 and two guide rods 233. The bidirectional lead screw 231 is drivingly connected to the second driving device 24. The two lead screw seats 232 are respectively threadedly connected to both ends of the bidirectional lead screw 231 and are respectively fixedly connected to the two clamping plates 21. The two guide rods 233 are fixed on the wire clamping frame 22, and the clamping plates 21 are slidably sleeved on the two guide rods 233. By driving the bidirectional lead screw 231 to rotate by the second driving device 24, the clamping plates 21 cannot rotate due to the limitation of the two guide rods 233, and the lead screw seats 232 drive the clamping plates 21 to slide along the bidirectional lead screw 231. By rotating the second driving device 24 forward, the two clamping plates 21 can be made to approach each other, and by rotating the second driving device 24 in reverse, the two clamping plates 21 can be made to separate from each other. The second driving device 24 can be a motor.

[0058] In some embodiments, the cable stripper further includes a cutter holder 5 and a proximity switch 6. The cutter holder 5 is movably mounted on the wire clamping frame 22.

By the proximity switch 6 sensing the distance from the cable, then moving the cutter holder 5 on the wire clamping frame 22 to make the cutter 3 contact the cable to complete the tool setting operation, and then driving the rotating seat 12 to rotate around the base 11 to realize the circumferential cutting of the insulating skin. The proximity switch 6 here does not involve specific improvements in software and algorithms, and uses the existing technology of the proximity switch 6.

[0059] In some embodiments, the cable stripper further includes a third driving device 7, a bearing seat 8, bearings 9, a driving shaft 10 and a slider 20. The third driving device 7 and the bearing seat 8 are mounted on the wire clamping frame 22. The third driving device 7 is connected to the driving shaft 10. Two bearings 9 are mounted on the bearing seat 8 and the clamping plate 21. The axis of the driving shaft 10 is parallel to the plane of the base 11. The driving shaft 10 is mounted in the two bearings 9 and is provided with an external thread. The bearing seat 8 is provided with a limiting sliding groove 81 parallel to the axial direction of the driving shaft 10. The slider 20 is provided with a threaded hole and the slider 20 is fixedly connected to the tool holder 5. The slider 20 is threadedly connected to the driving shaft 10 and is located in the limiting sliding groove 81. The limiting sliding groove 81 restricts the slider 20 to slide only along the limiting sliding groove 81, so as to realize the position adjustment of the tool holder 5, and thus adjust the distance between the tool 3 and the cable. The third driving device 7 may adopt a motor.

[0060] In some embodiments, the cable stripper further includes a wrench 30. The wrench 30 is connected to the bidirectional lead screw 231. When the driving motor is damaged or powered off and cannot be used, the bidirectional lead screw 231 is manually rotated through the wrench 30, so as to realize the mutual separation or approach of the two clamping plates 21, and improve the reliability and stability of the device.

[0061] The working principle of the cable stripper is as follows: The opening 121 is sleeved on the cable by holding the handle 4 by hand. The two clamping plates 21 approach each other to clamp the cable therebetween and can slide on the cable. During the process of the rotating seat 12 rotating relative to the base 11, the tool 3 cuts the insulating skin of the cable. The axis of the tool 3 has an adjustable angle with the reference plane, so that the tool 3 slides along the cable while cutting, thereby realizing the stripping of a longer cable. The stripping process is automatically completed, which can improve the stripping efficiency and can realize live working without affecting the efficiency of power construction.
