When the lifting column 13 descends, the second push block 222 on the lifting column 13 will gradually be disconnected from the second push block 2212, the blocking block 21 will gradually reset, when the lifting column 13 continuously descends, the second push block 222 on the lifting column 13 will press down the third push block 223, according to the lever principle, when one end of the third push block 223 descends, the other end of the third push block 223 will push the push rod 225 to move towards the direction far away from the base 11, the push rod 225 will push the first push block 2211, so that the blocking block 21 can be pushed towards the wall surface of the lifting column 13, that is, the gap between the embedded shell 12 and the lifting column 13 can be sealed through the blocking block 21. When the lifting column 13 is at the lowest position, the second pushing block 222 always applies pressure to the third pushing block 223, and the plugging block 21 will always seal between the embedded shell 12 and the lifting column 13.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: equivalent changes in structure, shape and principle of the present application shall be covered by the protection scope of the present application.
