At this time, the gear 71 fixedly mounted on the rotating rod 41 will rotate along with the rotating rod 41, and the rack 72 arranged at the bottom of the gear 71 will mesh with the gear 71 and move, and push the limit rod 61 through the connecting rod 73, so that the limit rod 61 slides on the adjusting block 33 and is inserted into the limit slot 6 opened in the supporting box 101. 2, the adjusting block 33 is limited, so that the weight in the weight-bearing assembly 8 is transferred to the support box 101 to prevent the weight of the weight-bearing assembly 8 from further causing harm to the patient. When the patient has rested, the motor 43 is reversed through the control assembly 5, so that the limiting rod 61 is pulled out of the limiting groove 62 under the meshing action of the gear 71 and the rack 72, and the adjusting block 33 is separated from the support box 101, so that the weight in the weight-bearing assembly 8 is transferred to the patient's arm through the first traction rope 31 and the second traction rope 34 to traction the patient's arm.

[0032] When the limiting rod 61 is inserted into the limiting groove 62, the adjusting block 33 will move downward as a whole under the influence of the weight-bearing component 8. At this time, the limiting block 61 will press the set blocking plate 13 and the spring 14. The set blocking plates 13 and the spring 14 will buffer the gravity generated when the weight-bearing component 8 falls, thereby preventing the force generated when the weight-bearing component 8 falls from being transmitted to the patient's arm and causing injury to the patient.

At this time, by rotating the first adjusting threaded rod 92, the moving block 93 is moved on the first adjusting threaded rod, and drives the support plate 102 to move to a height suitable for the patient.

[0039] By fixing the bone screw 32 to the patient's affected part, and then embedding a suitable number of weight blocks 83 into the embedding groove 82, the patient's arm is pulled under the action of the second traction rope 34, the first traction rope 31, and the adjustment block 33. When the patient feels uncomfortable, a control sound, such as "stop" or "limit" can be issued. When the sound receiver 51 receives the corresponding control sound, it will control the motor 43 to rotate, so that the motor 43 controls the rotating rod 41 and the rotating roller 42 to rotate, so that the first traction rope 31 wound around the rotating roller 42 is loosened, avoiding the weight component 8 The gravity continuously acts on the patient's arm, and the gear 71 fixedly mounted on the rotating rod 41 will rotate along with the rotating rod 41. The rack 72 arranged at the bottom of the gear 71 meshes with the gear 71 and moves. The limiting rod 61 is pushed through the connecting rod 73, so that the limiting rod 61 slides on the adjustment block 33 and is inserted into the limiting groove 62 opened in the support box 101 to limit the adjustment block 33, thereby transferring the weight in the load-bearing component 8 to be borne by the support box 101, preventing the weight of the load-bearing component 8 from further causing harm to the patient.

[0040] When the patient has rested, he can make a control sound, such as "rotate" or "start". When the sound receiver 51 receives the corresponding control sound, it will control the motor 43 to rotate in the opposite direction, so that the motor 43 controls the rotating rod 41 and the rotating roller 42 to rotate and wind up the first traction rope 31 to make it tight.

[0041] Under the meshing action of the gear 71 and the rack 72, the limiting rod 61 is pulled out of the limiting groove 62, and the adjustment block 33 is separated from the support box 101, so that the weight in the load-bearing component 8 is transferred to the patient's arm through the first traction rope 31 and the second traction rope 34 to pull the patient's arm.
