[0024] The support plate 16 is hinged to the rear side of the support seat 14. The baffles 25 are fixedly connected to the left and right sides of the support seat 14. The baffles 25 can prevent the winding roller 9 from rolling from the support plate 16 onto the support seat 14 and shifting to the left or right. Two limiting plates 23 are fixedly connected to the front side of the support seat 14. The shaft roller 22 is rotatably connected between the two limiting plates 23. The limiting plates 23 can prevent the winding roller 9 from rolling forward off the support seat 14.

[0025] One end of the second rotating shaft 20 is fixedly connected to the limiting block 11, and the other end of the second rotating shaft 20 is provided with a threaded hole. The threaded hole of the second rotating shaft 20 is internally connected to the bolt 17, and the second rotating shaft 20 is slidably connected to the locking block 18, which is located between the bolt 17 and the support seat 10 on one side of the bolt 17.

[0026] A first pulley 7 is fixedly connected to the first rotating shaft 19, a motor 12 is fixedly connected to the base 13, a second pulley 21 is fixedly connected to the rotating shaft of the motor 12, and a belt 8 is connected between the second pulley 21 and the first pulley 7.

[0028] The winding roller 9 is located above the support 14.

[0029] The working principle of this utility model is as follows: The fully wound winding roller 9 is rolled onto the support seat 14 via the support plate 16. The height of the hydraulic cylinder 15 is adjusted so that the second bearing 24 inside the support seat 10 is coaxial with the winding roller 9. The second rotating shaft 20 is inserted into the two second bearings 24 and the shaft of the winding roller 9. Then, a retaining block 18 is placed on the side of the second rotating shaft 20 with the threaded hole, and then a bolt 17 is inserted into the second rotating shaft 20. Then, the hydraulic cylinder 15 is activated to raise the winding roller 9 so that it does not contact the support seat 14. Then, the cable is passed along the bottom of the shaft roller 22 close to the support seat 14. The cable is then passed between the first roller 5 and the second roller 6. Depending on the cable thickness, the height of the slide block 4 and the first roller 5 can be adjusted by rotating the screw 2, thereby adjusting the clamping degree of the cable. After adjustment, the motor 12 is started. The motor 12 drives the first pulley 7 to rotate, which in turn drives the first rotating shaft 19 and the second roller 6 to rotate. As the second roller 6 rotates, the cable clamped between the first roller 5 and the second roller 6 can be pulled outward. The worker only needs to adjust the direction of the cable. The surfaces of the first roller 5 and the second roller 6 can also be designed with raised shapes to increase friction.
