[0021] Specifically, in the embodiment, one end of the vertical shaft 6 is pushed by the first air cylinder 7, so that the vertical shaft 6 changes the angle in the arc-shaped rotating seat 5, thereby driving the oscillating seat 2 to change the angle. The oscillation of the oscillating seat 2 can drive the oscillation of the whole backrest. Since the backrest shaft on one side of the backrest is abutted against the rotating positioning table 3 and the rotating limiting mechanism by the backrest support seat 4 and the top rod clamp mechanism, when the backrest rotates, the backrest shaft can rotate relative to the rotating positioning table 3, but cannot move horizontally.
