[0042] When the basket is not used for storage, the frame assembly is in a horizontal state, and the connecting belt and the center rod 2 are removed, so that the storage space can be greatly reduced. When used, the center rod 2 is installed, then the mounting column 3 is rotated to adjust the frame assembly to a vertical state, the push rod 12 is slid downward along the push rod limiting groove 14 and is fixed in the clamping hole at the bottom of the push rod limiting groove 14, at this time, the second air bag 9 is compressed, so that the air in the second air bag 9 enters the first air bag 8, the first air bag 8 expands and extends to push the butt joint 5, so that the end of the butt joint 5 extends into the cross-shaped clamping groove of the limiting sleeve 13, that is, the mounting column 3 is fixed, and the frame assembly can be adjusted to a vertical state, and then the connecting belt is fixed to be used.

[0043] Referring to Figures 7-12On the frame assembly, an adjustable protection assembly is arranged, which comprises two symmetrical side rods 17, and a grid net 18 is arranged between the two side rods 17. The grid net 18 is of a grid structure, and is a metal grid or a synthetic fiber grid welded on the side walls of the two side rods 17. If the grid net 18 is a synthetic fiber grid, nylon ropes, polyester ropes or polypropylene ropes with good corrosion resistance can be used, and a hole ring for fixing the ropes needs to be welded on the side wall of the side rod 17. A lifting block 19 is slidably arranged in the upper end of the mounting column 3, and a push spring 20 is connected to the bottom of the lifting block 19 and fixed to the baffle inside the mounting column 3.
