The outer surface of the rotating shaft 12 is sleeved with a second support part 18. In the early stage of orthopedic recovery, the user wears the first support part 11 and the second support part 18 on the forearm and the palm respectively, and the second support part 18 is prevented from rotating by the engagement of the rotating shaft 12 and the blocking cover 13, and the two ends are fixed and limited by the clamping block 14 clamped in the clamping slot 15. When rotation exercise is required, the blocking cover 13 is pulled outward, and the blocking cover 13 is twisted ninety degrees after being pulled out. At this time, the blocking cover 13 is loosened, and the two support blocks 17 are fitted together to make the clamping block 14 away from the clamping slot 15. The second support part 18 can be rotated by the rotating shaft 12 to help restore the flexibility of the wrist joint, enhance muscle strength, and perform exercise and rehabilitation.
[0027] The first support part 11 and the second support part 18 are both provided with ventilation holes 19. The upper ends of the first support part 11 and the second support part 18 are fixedly connected with connecting blocks 21. The two connecting blocks 21 are both on the same horizontal line. The insides of the two connecting blocks 21 are both sleeved with round rods 22. The outer surfaces of the two round rods 22 are sleeved with tension springs 23. The user wears the first support part 11 and the second support part 18 on the forearm and the palm respectively to support and correct the wrist. After wearing it for a period of time, the second support part 18 can be rotated by the rotating shaft 12. When worn, the joints can be rotated to help restore the flexibility of the wrist joint, enhance muscle strength, and perform exercise and rehabilitation. During the rotation exercise, the first support part 11 and the second support part 18 are dynamically pulled by the tension spring 23.

When rotation exercise is needed, pull the blocking cover 13 outward, and rotate it ninety degrees after the blocking cover 13 is pulled out. At this time, loosen the blocking cover 13, and the two support blocks 17 fit together, so that the blocking block 14 is away from the card slot 15, and the second support part 18 can be rotated by the rotating shaft 12 to help It helps restore the flexibility of the wrist joint, enhance muscle strength, and perform exercise and rehabilitation. When the second support part 18 is rotated, the tension spring 23 is used to dynamically pull the muscles. The threaded rod 25 is screwed by holding the handle 26. During the rotation of the threaded rod 25, the rectangular block 24 drives the round rod 22 to slide. The round rod 22 slides to adjust the placement position to adjust the force of the tension spring 23. The user can adjust the traction force according to his or her own recovery status and the doctor's adjustment of the tension spring 23, thereby improving the flexibility of the device and adapting to different usage needs.
