The top inner walls of the front panel 14 and the rear panel 15 are fixedly connected to a fixed block, and the top outer wall of the fixed block is provided with a pin hole 9. A sliding shaft 3 is provided on one side outer wall of the bottom of the column 20, a long arm 2 is provided on one side outer wall of the front panel 14 and the rear panel 15, and a short arm 1 is provided on the other side outer wall of the front panel 14 and the rear panel 15.

[0023] Furthermore, a slide groove 17 is provided on the outer wall of one side of the column 15, and the sliding shaft 3 is slidably connected to the inner wall of the slide groove 17. The column 15 and the column 2 20 are both rectangular in shape, and the sizes of the column 15 and the column 2 20 are adapted. A through hole is provided on the outer wall of the bottom end of the square base plate 16, and the through hole is adapted to the size of the connecting pin 18.

[0024] Furthermore, the top outer wall of the column 20 is fixedly connected to the cover plate 21, the top outer wall of the cover plate 21 is fixedly connected to the hook 19, the long arm 2 and the short arm 1 are adapted to the size of the horizontal angle steel, the spacing between the front panel 2 10 and the rear panel 2 11 is adapted to the spacing between the front panel 1 4 and the rear panel 1 5, and the bottom outer walls of the front panel 2 10 and the rear panel 2 11 are fixedly connected to the hanging rod 13.
