The torsion spring 302 cooperates with the adjusting connecting column 101a-5, one end of which is connected to the adjusting connecting column 101a-5, and the other end is connected to the connecting ring 301a. In the initial state, the torsion spring 302 provides a torsion force for the adjusting rod 301 that is biased toward the side wall of the intersection groove 101a.

[0045] When in use, according to the wiring situation, when there are cables that need to be turned, the adjustment rod 301 in the corresponding direction is rotated to form a cable placement partition with the side wall of the intersection groove 101a, and then the cables tied into groups are arranged in the formed partition according to the designed direction. Under the torsion of the torsion spring 302, the limit rod 301b isolates the cables in this direction from the cables in other directions to complete the wiring work.

[0046] In summary, by providing the adjustment rod 301, the cables that need to be turned can be placed in partitions, so that the lines are clear and orderly, easy to manage, and safer.
