The gear and the circular rack mesh to drive the third driven member 412 to move horizontally. In this case, the gear is in a flat state, and the rotation of the gear can drive the circular rack, i.e., the third driven member 412, to move horizontally. The third gear drive meshes with the gear driven member 414, thereby driving the third driven member 412 to rotate.

[0047] Furthermore, the third follower 412 can move horizontally within the fixed base 411, and the gear follower 414 can mesh and rotate with the second drive member 423.
