[0025] The workbench 1 is provided with a guide assembly 2, which includes a fixed plate 201 that is fixedly connected to the workbench 1.

[0026] A vertical slide groove 202 is provided on the fixed plate 201, and a slide plate 203 is slidably connected in the vertical slide groove 202. An electric push rod 204 is installed on the fixed plate 201, and the driving end of the electric push rod 204 is fixedly connected to the slide plate 203. By extending and retracting the electric push rod 204, the slide plate 203 can be driven to slide up and down in the vertical slide groove 202.

[0027] The fixed plate 201 has several evenly distributed transverse grooves 205, the length of which decreases from top to bottom.

[0028] A clamping block 206 is slidably connected within the transverse slide groove 205. A connecting rod 207 is fixedly connected to the clamping block 206, and the end of the connecting rod 207 away from the clamping block 206 is fixedly connected to the slide plate 203. When the slide plate 203 slides up and down, the connecting rod 207 can drive the clamping block 206 to slide within the transverse slide groove 205, thereby achieving the clamping and releasing operation of the cable.

[0029] The bottom of the workbench 1 is provided with support legs 11 to support the entire device. A fixed step shaft 3 is rotatably connected to the workbench 1. Each step of the fixed step shaft 3 is provided with a first guide groove 4, which is used to position and guide the high-voltage cable.

[0030] The worktable 1 has an arc-shaped slide groove 5. A rotating cylinder 6 is rotatably connected to the bottom of the worktable 1. A fixed shaft 7 is fixedly connected to the rotating cylinder 6. The arc-shaped slide groove 5 and the fixed shaft 7 are slidably arranged so that when the rotating cylinder 6 rotates, the fixed shaft 7 can slide along the arc-shaped slide groove 5, thereby realizing the movement of the components connected to the rotating cylinder 6.

[0031] The fixed shaft 7 is rotatably connected to the top of the movable step shaft 8. Each step of the movable step shaft 8 is provided with a second guide groove 10.

An internal gear 903 is fixedly installed on the inner wall of the rotating cylinder 6. The spur gear 902 and the internal gear 903 mesh with each other.

[0033] When the motor 901 is working, it drives the spur gear 902 to rotate. Through the meshing of the spur gear 902 and the internal gear 903, the rotating cylinder 6 rotates, which in turn drives the fixed shaft 7 and the movable step shaft 8 connected to the rotating cylinder 6 to rotate, thereby realizing the bending operation of the high-voltage cable.

[0034] When bending a high-voltage cable, first determine the bending arc of the high-voltage cable, confirm the height of the first guide groove 4 and the second guide groove 10, and pass the high-voltage cable through the transverse slide groove 205 corresponding to the height of the first guide groove 4 and the second guide groove 10.
