[0024] Here’s how it works:

[0025] First, a hole is drilled at the installation position of the wall 6 to be fixed, and the threaded hole 2 of the rectangular plate 1 is aligned with the hole of the wall 6, and the screw 5 is threadedly connected with the threaded hole 2 and the hole, so that the rectangular plate 1 is fixed on the wall 6;

[0026] Second, by rotating the circular sleeve 313 of the covering structure 31, the mark of the circular sleeve 313 is rotated to the same position as the sliding groove 312, and the circular sleeve 313 is moved leftward. The circular sleeve 313 uses the sliding cooperation between the sliding block 314 and the sliding groove 312 to make the sliding block 314 move leftward, thereby releasing the covering effect;

[0027] Third, the pressing block 3355 of the first limiting structure 33 and the second limiting structure 34 are pressed by hand at the same time, and the pressing block 3355 of the first limiting structure 33 moves downward.
