[0038] In the embodiment, the vehicle body 1 with the supporting mechanism is arranged, one end of the vehicle body 1 is provided with the hanging rod 101, and both sides of the vehicle body 1 are provided with the supporting legs 102 which are screwed with the vehicle body 1. Figures 1 to 8The bottom of the first supporting rod 8 is provided with a sliding block 14, and the sliding block 14 is slidably connected with the lifting seat 2 through a sliding groove 15. The lifting seat 2 is internally provided with a tension spring 16 and a clamping block 17, and one end of the tension spring 16 is fixedly connected with the sliding block 14. The sliding block 14 is provided with a clamping hole 1401 which is matched with the clamping block 17.

[0039] The lifting seat 2 is further provided with an adjusting rod 19. One end of the adjusting rod 19 is provided with a wedge-shaped block 37, and the other end of the adjusting rod 19 is fixedly connected with the clamping block 17. The adjusting rod 19 is elastically connected with the lifting seat 2 through the first spring 18.

[0040] The lower side of the bracket 4 is provided with a second supporting rod 20, and one end of the second supporting rod 20 is fixedly connected with the lifting seat 2. The second supporting rod 20 is provided with a second spring 21. One end of the bracket 4 passes through the second supporting rod 20 and abuts against the inclined surface of the adjusting rod 19.

[0041] In order to improve the operation convenience of the cable reel 5, the application further provides a driving motor 9 which is connected with the center rod 7 through a connecting assembly. Under the driving of the driving motor 9, the center rod 7, the limiting shaft 6 and the cable reel 5 can be driven to rotate, thereby achieving the purpose of automatic pay-off. In order to improve the convenience of the connection between the driving motor and the center rod 7, the technical solution provides a movable connecting assembly which is arranged on the first supporting rod 8. The first supporting rod 8 can slide on the lifting seat 2 through the sliding block 14. Correspondingly, the lifting seat 2 is further provided with the adjusting rod 19 and the clamping block 17. The clamping hole 1401 which is matched with the clamping block 17 is arranged on the sliding block 14. The clamping block 17 is fixed on the adjusting rod 19, and the adjusting rod 19 is elastically connected with the lifting seat 2 through the first spring 18. Meanwhile, the wedge-shaped block 37 is arranged on one end of the adjusting rod 19.

[0042] In the initial state, the height of the bracket 4 is higher than that of the connecting seat 11. When the opening slot 401 on the bracket 4 is aligned with the center rod 7, the hydraulic cylinder 3 pushes the lifting seat 2 upward. With the movement of the lifting seat 2, the bracket 4 abuts against the center rod 7. Under the influence of the center rod 7 and the self-weight of the cable reel 5, the bracket 4 overcomes the resistance of the second spring 21 and relatively slides with the second supporting rod 20. In this process, the bottom end of the bracket 4 abuts against the wedge-shaped block 37 on the adjusting rod 19, thereby pushing the adjusting rod 19 to move away from the sliding block 14. Under the driving of the adjusting rod 19, the clamping block 17 is pulled out of the clamping hole 1401. After losing the limiting of the clamping block 17, the sliding block 14 moves toward the bracket 4 under the pushing of the tension spring 16, thereby promoting the connecting seat 11 to be clamped with the center rod 7.

[0043] When the connecting seat 11 moves along the axial direction of the central rod 7, if the position of the connecting claw 13 is exactly opposite to the limiting groove 701, the connecting claw 13 can be directly inserted into the limiting groove 701. Then, the drive motor 9 drives the connecting claw 13, the connecting seat 11, and the central rod 7 to rotate. If the position of the connecting claw 13 is misaligned with the limiting groove 701, this technical solution provides an inclined surface at the end of the connecting claw 13 and a groove for accommodating the connecting claw 13 is opened on the inner wall of the connecting seat 11. During the contact process, the connecting claw 13 overcomes the resistance of the return spring 35 and retracts into the groove. As the connecting seat 11 rotates, when the connecting claw 13 reaches the position of the limiting groove 701, the connecting claw 13 can be inserted into the limiting groove 701 under the push of the return spring 35, thereby completing the connection with the central rod 7. This technical solution does not require manual adjustment and can automatically complete the connection of the drive motor 9, the connecting assembly, and the central rod 7, greatly reducing the labor intensity of workers.

[0044] This technical solution cleverly utilizes the resistance generated during the process of supporting the cable reel 5, and in conjunction with the bracket 4, the second support rod 20, and the lifting seat 2 with the adjusting rod 19, the slider 14, and the locking block 17, it can automatically complete the connection between the connecting components and the central rod 7, resulting in a higher degree of automation and effectively reducing the labor intensity of the operators.
