The first long bolt rod 4 is rotated to drive the support plate supporting part 2 to move up and down, and the bracket of the support plate supporting part 2 is adjusted to the required height for the installation of the horizontal support plate 12.

[0022] A pair of bolt holes are provided inside the hook part 1 and a second fixing nut 6 is welded inside the hook part 1. A short bolt rod 7 is screwed on the second fixing nut 6. The short bolt rod 7 is rotated to press against the inner side of the lattice column plate 11 to achieve the locking of the hook part 1.
