The connection base is arranged outside the second arm with respect to the reducer and connected to the first output shaft. The first auxiliary link is arranged parallel with the first arm and has an end pivotally connected to the fixed base and an end pivotally connected to the connection base. The second auxiliary link is arranged parallel with the second arm and has an end pivotally connected to the connection base and an end pivotally connected to the movable base.
