[0038] By adopting the above technical solution, the movable seat 14 is provided to drive the movable wheel 6 to move automatically, so that the cable can be evenly wound onto the take-up wheel 8, thereby improving the cable winding quality.

[0039] Specifically, a bearing rotating seat is arranged between the screw rod 13 and the fixed plate 7 , a threaded hole corresponding to the screw rod 13 is arranged in the movable seat 14 , and the lower end of the movable seat 14 is flush with the upper end of the connecting plate 2 .

[0040] By adopting the above technical solution, the rotation of the screw rod 13 can drive the moving seat 14 to move, and the lower end of the moving seat 14 is flush with the upper end of the connecting plate 2, so that the movement of the moving seat 14 is more stable.

[0041] Specifically, the side of the vertical plate 15 is in close contact with the inner wall of the second slide groove 16, the vertical plate 15 and the movable seat 14 are welded into an integrated structure, and the vertical plate 15 and the I-shaped slide block 4 are welded by spot welding.

[0042] By adopting the above technical solution, the vertical plate 15 is prevented from shaking in the second slide groove 16. The vertical plate 15 and the movable seat 14 are welded into an integrated structure, which is more solid. Spot welding makes the vertical plate 15 and the I-shaped slider 4 more solid.

[0043] When this embodiment is used, by setting a movable seat 14, when the take-up wheel 8 rotates to reel in the cable, the motor 2 12 is turned on to drive the screw rod 13 to rotate, and the rotation of the screw rod 13 drives the vertical plate 15 at the lower end of the movable seat 14 to move in the slide groove 2 16 of the connecting plate 2, and the movement of the vertical plate 15 drives the I-shaped slider 4 to move in the slide groove 10, and the I-shaped slider 4 moves through the cross plate 5 to drive the movable wheel 6 to slide on the guide rod 17, and the movable wheel 6 moves so that the cable can be evenly reeled onto the take-up wheel 8.
