When in use, the dustproof net, the spring frame, the spring disk, the fixed column, the limit column and the telescopic column are arranged, and the fixed column is manually pushed down vertically by hand to lower it, and the fixed column pulls the dustproof net to compress the spring disk and extend it out of the outside of the spring frame at the same time, and the extension is pressed.
