When working, after wearing the arm rehabilitation training device, it is difficult for the user to take it off because the fixation is too firm. By controlling the structure of the component, by pulling The round rod 11 in the chute 10 on the top side of the hollow connecting seat 7 makes it drive the block 9 back to the inner side of the hollow connecting seat 7, thereby contacting the fixing between the fixing belt 5 and the fixing seat 3, and the arm rehabilitation training can be performed at this time. The device is taken off, easy to operate and more convenient to use.

Embodiment two

Please refer to Fig. 6, comparative example 1, as another embodiment of the present utility model, a telescopic tube 23 is fixed between the limiting plate 18 and the support plate 17, and the telescopic tube 23 is sleeved on the second On the spring 19; when working, in the process of stretching or compressing the second spring 19, the spring is easy to accidentally pinch clothes or hair, and when it is inconvenient to use, the second spring 19 is closed by the structure of the telescopic tube 23 At the same time, it will not affect the expansion and contraction process of the second spring 19, which is more convenient to use.

Working principle, the arm rehabilitation training device is mainly used for arm muscle atrophy caused by postoperative or other diseases. When the patient's arm muscle atrophy leads to inability to move normally, the arm rehabilitation training device enables the patient to bend the arm while giving A certain resistance with the arm, so as to train the muscles and promote the recovery effect of the arm. When the existing arm rehabilitation trainer is in use, the stretching direction of the spring changes according to the bending of the arm, resulting in a relatively low utilization rate of the spring force. Low, reducing the effect of rehabilitation training, and when the wearer is exhausted, the tension of the spring will pull the arm to straighten suddenly, causing the user's arm to be strained. In order to solve this problem, by setting a protective mechanism and a fixed mechanism, the user wears , the upper arm sleeve 1 and the forearm sleeve 2 can be set on the arm, and the fixing belt 5 is driven to move by pulling the handle 6, so that the fixing belt 5 is buckled into the fixing seat 3, so that the first spring 8 pushes the card through the elastic force The block 9 is buckled on the fixed block 4, and the upper arm sleeve 1 and the forearm sleeve 2 are fixed on the arm. The initial state of the second spring 19 is a stretched state. The mounting seat 22 of the connecting rod 21 is moved, and with the cooperation of the rotating seat 20, the second spring 19 is pulled by the support plate 17 to stretch, and at the same time, with the cooperation of the piston rod 16, the piston 14 is pulled to move in the hydraulic cylinder 13, At this time, the hydraulic oil at one end of the hydraulic cylinder 13 flows to the other end through the hole 15 on the surface of the piston 14, so that the piston rod 16 is slowly extended. When the user is exhausted, under the cooperation of the piston rod 16 and the piston 14, the second spring 19 Pull the support plate 17 to retract slowly to protect the user's arm from being hurt. After use, pull the round rod 11 in the chute 10 on the top side of the hollow connection seat 7 to drive the block 9 back to the inside of the hollow connection seat 7. Thereby contact fixing between fixing belt 5 and fixed seat 3, arm rehabilitation trainer can be taken off this moment, solved arm rehabilitation trainer when the wearer is exhausted, the problem of easily straining arm.
