The lower end of the rotating shaft 70 extends out of the shaft hole 60 and connects to the movable seat 20 for synchronous rotation. A rotating module 80 is provided on the mounting frame 30 to drive the rotating shaft 70 in a fixed rotational direction. The rotating shaft 70 is coaxially arranged with the movable terminal of the lifting module 40. When fully assembled, the upper end of the movable seat 20 slides horizontally against the lower surface of the mounting frame 30.

[0026] In order to further improve efficiency and facilitate mass production, the movable seat 20 and the mounting frame 30 as well as the rotating module 80 and the lifting module 40 are each provided with two groups and are arranged along the length direction of the base 10. Correspondingly, there are also two hemispherical grooves 50 on the base 10.
