[0022] Among them, a T-shaped slot 17 is opened on the top of the movable plate 5, a T-shaped slider 18 is installed inside the T-shaped slot 17, and the T-shaped slider 18 is slidably connected to the T-shaped slot 17, so that the stability of the movable seat movement is improved by the T-shaped slot 17 and the T-shaped slider 18.
