[0025] Next, in combination with the drawings and the specific embodiments, the invention will be further described:

[0026] Embodiment 1

[0027] Please refer to Figures 1 to 2Description of Embodiment 1, including a bottom plate 10. At the upper end of the bottom plate 10, there are two first support columns 11. The first support columns 11 are used to install a transmission shaft 13 to achieve a supporting effect. The transmission shaft 13 is rotatably connected inside the first support column 11. One end of the transmission shaft 13 is fixedly connected to the output end of the motor 12. A number of traction components 20 are arranged in an array on the transmission shaft 13. The motor 12 drives the transmission shaft 13 to rotate, thereby driving the traction components 20 to work. The traction components 20 include traction rollers 21. At the lower end of the traction rollers 21, there are clamping rollers 24. The traction rollers 21 and the clamping rollers 24 have an interference fit with the cable. The interference fit between the traction rollers 21 and the clamping rollers 24 can better clamp the cable for traction. The traction rollers 21 are fixedly connected to the transmission shaft 13. On the surface of the traction rollers 21, there are traction concave surfaces 22. At both ends of the traction rollers 21, there are thrust shafts 23 fixedly connected to the transmission shaft 13. The transmission shaft 13 drives the traction rollers 21 to rotate. The setting of the traction concave surfaces 22 fits the cable better. The function of the thrust shafts 23 is to prevent the traction rollers 21 from shifting. On the surface of the clamping rollers 24, there are clamping concave surfaces 25. The clamping rollers 24 are rotatably connected to the support seats 26. The setting of the clamping concave surfaces 25 fits the cable better. The support seats 26 are used to support the clamping rollers 24. On the bottom plate 10, there are also two second support columns 14. On the opposite sides of the second support columns 14, there are fixedly connected bearing seats 15. Inside the bearing seats 15, there is a rotating rod 16 that holds up the cable. The rotating rod 16 holds up the cable, reducing the friction with the ground and saving energy;

[0028] In this embodiment, when the motor 12 is started, it drives the transmission shaft 13 to rotate. The rotation of the transmission shaft 13 drives the traction rollers 21 to rotate. The cable is inserted between the traction rollers 21 and the clamping rollers 24. The interference fit between the traction rollers 21 and the clamping rollers 24 and the cable can stably clamp the cable. When the traction rollers 21 rotate, they drive the cable for traction, and the clamping rollers 24 rotate in cooperation. By setting multiple sets of traction components 20, multiple cables can be tractioned, improving the efficiency. The setting of the rotating rod 16 can hold up the cable, reducing the resistance of cable traction and reducing energy consumption. The settings of the traction concave surfaces 22 and the clamping concave surfaces 25 can better fit the cable, increasing the contact area and improving the traction effect. Moreover, the traction concave surfaces 22 and the clamping concave surfaces 25 have a certain limiting effect, which can prevent the cable from falling off.

[0031] In this embodiment, by rotating the adjusting block 36, the rotation of the adjusting block 36 drives the rotation of the threaded rod 35, the rotation of the threaded rod 35 cooperates with the threaded sleeve 39 to raise the threaded rod 35, the raising of the threaded rod 35 can jack up the rotating seat 34, the jacking up of the rotating seat 34 jacks up the support base 26, so that the gap between the clamping roller 24 and the traction roller 21 can be reduced to clamp a thinner cable. On the contrary, it is convenient to clamp a thicker cable, and various specifications of cables can be applicable. Moreover, the sliding rods 33 and the sliding holes 32 are provided to limit the support base 26 and prevent the support base 26 from rotating along with the threaded rod 35, thereby improving the stability.
