[0035] In a preferred embodiment, as shown in Figure 3 、 Figures 5 to 7 The upper end of the rotating disc 2 is provided with an annular column 21, and the upper edge of the annular column 21 is provided with at least one V-shaped slot 22. When the movable support 3 is in the first active position, the front end of the limiting member 4 at least partially extends into the V-shaped slot 22 to limit the circumferential rotation of the rotating disc 2. Further, the movable support 3 is further provided with a limiting wheel 5. When the movable support 3 is in the first active position, the limiting wheel 5 abuts against the inner wall of the annular column 21.
