The other end of the short shaft is rotatably connected to the side wall of the ear plate. The ear plate is fixedly connected to the two sides of one end of the rotating frame. The side wall of the strip block is provided with a first slide groove, and an elastic member is fixedly connected to the top surface of the first slide groove. The free end of the elastic member is fixedly connected to the first slider, and the first slider is slidably engaged in the first slide groove. The side wall of the rotating frame is provided with a second slide groove, and a second slider is slidably engaged in the second slide groove. The second slider and the side walls of the first slider are respectively hinged to the two ends of the connecting rod. This technology discloses that "in the process of the patient slowly pressing down the rotating frame, the intensity of the rehabilitation training can be controlled according to the pain of the body, which is safer than manual operation and makes the patient's rehabilitation training effect better."

[0030] When an existing postoperative rehabilitation training auxiliary device for elbow fracture is in use, the device supports the patient's arm through two rotating frames. Since the height and spacing of the two rotating frames are fixed, it is easy for the patient to place his arm too high or too low on the rotating frames, which will accelerate physical fatigue and cause discomfort to the patient, making it difficult for the patient to persist in using the device for a long time, thereby reducing the rehabilitation effect of the device on the patient's elbow joint. Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a first slide rail and a second slide rail are added to the present application document.
