During the rotation of the double-headed screw 602, the two transmission auxiliary frames 605 push the two clamping positioning plates 6 to slide inward synchronously. During the synchronous inward sliding of the two clamping positioning plates 6, automatic clamping of both sides of the affected limb is realized; when the patient's upper limbs become fatigued due to maintaining the same action for a long time, causing the patient's upper limb to be lifted or excessively exerted, the force monitoring plate 5 and the connecting shaft 501 flip over synchronously. During the flipping of the connecting shaft 501, the striking ball head 502 hits the warning auxiliary ring 503 to make a sound, which automatically warns the patient and avoids a series of unnecessary troubles caused by excessive exertion of the upper limbs.
