After the cable laying work is completed, the positioning unit 46 is removed, and then the rotating rod 452 is rotated to open the fixed rod 451 and the rotating rod 452, and the cable is taken out from between the groove wheel 44 and the fixed rod 451 and the rotating rod 452; after the removal work is completed, the rotating rod 452 is rotated in the opposite direction, and then the fixed rod 451 and the rotating rod 452 are fixed and reset through the positioning unit 46.

The connecting rod 4523 is rotationally limited in the installation groove by the limiting head 4524. Under the limiting action of the limiting head 4524, the semi-U-shaped rotating rod 4521 can rotate on the bottom frame plate 41; and

[0059] A rectangular through groove 4525 is provided at the upper end of the arc-shaped end of the semi-U-shaped rotating rod 4521. The rectangular through groove 4525 is arranged corresponding to the positioning block 4514, and positioning holes 4526 are provided on the semi-U-shaped rotating rod 4521 at the upper and lower ends of the rectangular through groove 4525. The positioning holes 4526 are arranged corresponding to the through holes 4515, and the positioning hole 4526 at the upper end of the rectangular through groove 4525 is a threaded inner hole, and the positioning hole 4526 at the lower end of the rectangular through groove 4525 is a straight hole.

When engaged, it is used for threading the cable; when separated, it is used for taking out the cable.

[0061] On the basis of the above technical solution, the cable can be quickly inserted and positioned in the groove wheel 44 through the U-shaped detachable lock buckle 45, ensuring the stability of the cable during the cable laying process, reducing the swing and friction of the cable, and reducing the instability of the tool during use, thereby reducing the risk of work accidents and improving the safety of workers. After the cable laying is completed, the U-shaped detachable lock buckle 45 can be used to remove the cable in the groove wheel 44 through a dynamic and static quick separation method. After removal, the U-shaped detachable lock buckle 45 can be re-locked using a dynamic and static quick locking method, making the entire process operation method simple and convenient, thereby reducing the operation time of the U-shaped detachable lock buckle 45 and improving construction efficiency.

After the cable removal work is completed, the positioning unit 46 is first reset by using a disassembly tool, and then the rotating rod 452 is rotated in the opposite direction. During the rotation of the rotating rod 452, the arc structure at the lower end of the positioning shaft rod 464 is lifted up, and the connecting spring 463 is compressed. After the positioning hole 4526 corresponds to the through hole 4515, the connecting spring 463 recovers its deformation, and the fixed rod 451 is engaged with the rotating rod 452 and the U-shaped separation lock buckle 45 is reset.
