[0024] Furthermore, a first spring 14 is fixedly connected between one side of the limit plate 13 and the first support plate 3. The limit plate 13 moves to squeeze the first spring 14, and the first spring 14 generates an elastic force. When the first spring 14 loses its pressing force, under the action of the elastic force, the first spring 14 returns to its original position with the first clamping block 12 through the limit plate 13.

[0025] Furthermore, one end of the first clamping block 12 passes through one side of the first supporting plate 3 and is fixedly connected to the moving plate 11 . When the moving plate 11 is moved, the moving plate 11 moves with the first clamping block 12 .

[0026] Furthermore, a hook 2 is fixedly connected to one side of the second fixing plate 8 to better fix the ladder to the outside of the grid.

[0027] Furthermore, a groove 17 is formed on one side of the first support plate 3 , a slide bar 19 is fixedly connected to the inside of the groove 17 , a moving block 20 is slidably connected to the outside of the slide bar 19 , and the moving block 20 moves along the slide bar 19 .

[0028] Furthermore, one end of the moving block 20 is fixedly connected to a connecting rod 21, and the end of the connecting rod 21 away from the moving block 20 is fixedly connected to a push plate 22. A second spring 18 is fixedly connected between the push plate 22 and the groove 17. The push plate 22 moves with the moving block 20 along the slide rod 19. The push plate 22 is pressed against the second spring 18 by the pushing force. When the second spring 18 loses its pressing force, the second spring 18 brings the push plate 22 back to its original position under the action of the elastic force.

[0029] Furthermore, one end of the support leg 15 away from the first support plate 3 is fixedly connected to a cross plate 16, a clamping hole 23 is provided at the bottom of the cross plate 16, and a second clamping block 24 is slidably connected to the inside of the first fixed plate 1, and the second clamping block 24 enters the clamping hole 23 to fix the position of the support leg 15.

When the second supporting plate 6 moves to a suitable position, the threaded hole 9 moves to one side of the first clamping block 12, and the first clamping block 12 loses its pressing force. Under the action of the elastic force, the first spring 14 enters through the limiting plate 13 with the first clamping block 12 The position of the second support plate 6 is fixed in the threaded hole 9, so that the hook 2 hooks the grid, and the ladder is fixed to one side of the grid. The bolt 10 is turned and screwed into the threaded hole 9 to further fix the second support plate 6 and the first support plate 3. The connecting plate 26 is moved, and the connecting plate 26 moves with the second clamping block 24.
