A hinged connection shaft (6) is provided between the fixed base (1) and the movable base (2), and the hinged connection shaft (6) is not collinear with a rotational axis (7) of the connecting member (5). A first connecting shaft (8a) is provided between the connecting end (51) and the fixed base (1); a second connecting shaft (8b) is provided between the connecting end (51) and the connecting rod (52); and a third connecting shaft (8c) is provided between the connecting end (51) and the damping connecting end (53), wherein the distance between the first connecting shaft (8a) and the second connecting shaft (8b) is smaller than the distance between the first connecting shaft (8a) and the third connecting shaft (8c).
