The movable block is fixed to one end of the connecting seat, the movable groove is opened at one end of the tube body, the movable groove and the movable block are in a snap-fit ​​state, and the silicone seat is fixed to the outer surface of the movable block.

[0008] As a preferred technical solution of the present invention, the connecting assembly consists of a rotating groove and a rotating block. The rotating block is fixed to the other end of the connecting seat. The rotating groove is opened at the other end of the tube body. The rotating block is inserted into the inner side of the rotating groove and is threadedly connected.
