In some embodiments of the present application, referring to fig. 2 and 3, the stationary seat member 10 further includes a ball 170. The opposite sides of the back plate 110 and the turntable 120 are respectively provided with an annular chute 113, and a plurality of balls 170 are respectively arranged inside the two groups of annular chutes 113 in a rolling manner.

By adopting the structural design that the back plate 110 and the rotary table 120 are provided with the annular sliding grooves 113 at opposite sides, the balls 170 between the rotary table 120 and the back plate 110 can reduce the friction force generated when the rotary table 120 rotates, so that the guide arc plate 330 at one side of the rotary table 120 can be adjusted more flexibly when rotating.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
