A centering mechanism for facilitating their centering is connected to the bottoms of the two groups of moving plates 14. One side of each of the two groups of moving plates 14 is connected to a clamping plate 16 through a rotating shaft 15. An inner support mechanism for facilitating the fixation of the winding drum 26 is installed on one side of each of the two groups of clamping plates 16. A driving mechanism for facilitating the rotation of the winding drum 26 is provided inside one of the two groups of moving plates 14. A guiding mechanism for facilitating the uniform winding of the cable is provided on the top of the bottom plate 1 on one side of the winding drum 26;

[0028] The centering mechanism includes an electric telescopic rod 12 installed on one side of the bottom plate 1. A cavity 5 is opened inside the bottom plate 1. Two groups of activity slots 6 communicating with the cavity 5 are opened on the top of the bottom plate 1. Two groups of support rods 7 are provided on the inner side of the cavity 5, and two groups of moving seats 8 are slidably connected. A rack plate 9 is correspondingly installed on one side of each of the two groups of moving seats 8. Both groups of rack plates 9 are engaged with a circular gear 10. A connecting shaft 11 rotatably connected to the cavity 5 penetrates through the inside of the circular gear 10. One side of one group of moving seats 8 is connected to one end of the electric telescopic rod 12. The bottoms of the two groups of moving plates 14 respectively penetrate through the inner sides of the two groups of activity slots 6 and are respectively connected to the tops of the two groups of moving seats 8.

[0029] Specifically, through the provided vehicle body, the device can be conveniently moved freely, and at the same time, it can provide a stable working platform for the cable tensioning operation. By starting the electric telescopic rod 12, the electric telescopic rod 12 can drive a set of moving seats 8 to move towards the center position of the cavity 5. A set of moving seats 8 can drive a set of rack plates 9 to move to one side. Through the meshing action between a set of rack plates 9 and the circular gear 10, the circular gear 10 can be driven to rotate. Through the meshing action between the circular gear 10 and another set of rack plates 9, the other set of rack plates 9 can be driven to move in the opposite direction. The other set of rack plates 9 can drive the other set of moving seats 8 to move in the opposite direction. Thus, the two sets of moving seats 8 can drive the two sets of moving plates 14 to approach each other, and the two sets of moving plates 14 can drive the two sets of clamping plates 16 to approach each other. Therefore, the two sets of clamping plates 16 can drive the two sets of inner support mechanisms to respectively penetrate into the inner sides of both ends of the cable take-up reel 26.

Through the threaded connection between the two sets of bidirectional screw rods 22 and the corresponding two sets of sliders 24, the corresponding two sets of sliders 24 can be driven to move to both sides. The two sets of sliders 24 can drive the two sets of support plates 25 to move to both sides. Thus, the two sets of support plates 25 can abut against and fix the inner wall of the cable take-up reel 26, and then the installation and fixation of the cable take-up reel 26 can be completed.

[0032] Among them, the driving mechanism includes a first motor 20. A transmission chamber 17 is provided inside a group of moving plates 14.

The two sets of moving plates 14 can drive the two sets of clamping plates 16 to approach each other, and drive the two sets of inner support mechanisms to respectively penetrate into the inner sides of both ends of the winding drum 26. Then, by rotating the two sets of knobs 23, the two sets of knobs 23 can drive the two sets of bidirectional screws 22 to rotate. The two sets of bidirectional screws 22 can drive the corresponding two sets of sliders 24 to move to both sides. The two sets of sliders 24 can drive the two sets of support plates 25 to move to both sides. Thus, the two sets of support plates 25 can abut and fix the inner wall of the winding drum 26 to complete the installation and fixation of the winding drum 26;

[0036] Then, by starting the first motor 20, the first motor 20 can drive the worm 19 to rotate. The worm 19 can drive the turbine 18 to rotate. The turbine 18 can drive the rotating shaft 15 to rotate. The rotating shaft 15 can drive the clamping plate 16 to rotate. Thus, the clamping plate 16 can drive the locked winding drum 26 to rotate to facilitate the cable tensioning operation. At the same time, by starting the second motor 32, the second motor 32 can drive the turntable 33 to rotate. The turntable 33 can drive the abutting rod 34 to rotate. Under the abutting action of the abutting rod 34 with the abutting groove 31 and in cooperation with the limiting action of the two sets of sliding rods 28 provided, it can drive the movable plate 29 to slide horizontally back and forth along the two sets of sliding rods 28.
