By rotating the support plate 3 inside the support plate 2, the device can be used standing or sitting. The device's usage state can be adjusted according to usage needs. At the same time, by rotating the double-acting screw 43 and the slide rod 41 to make threaded movements, the distance between the two support rods 42 can be adjusted, so that the device can provide protection during use and prevent it from tipping over.

[0024] Please see Figure 1 , Figure 3 , Figure 4 The training mechanism 9 includes a suspension rod 91, with the lower end of the suspension rope 7 fixedly connected to the suspension rod 91. A slide cylinder 92 is slidably connected to the outer side of the suspension rod 91. A baffle 93 is fixedly connected to the lower end of the suspension rod 91, and the baffle 93 and the slide cylinder 92 are slidably connected. A spring 94 is provided on the outer side of the suspension rod 91, with one end of the spring 94 fixedly connected to the slide cylinder 92 and the other end of the spring 94 fixedly connected to the baffle 93. By providing the spring 94, the slide cylinder 92 can be easily reset. A guide rail 95 is fixedly connected to the lower end of the slide cylinder 92. The inner side of the guide rail 95... The device is equipped with a support sleeve 96, and a retaining ring 97 is fixedly connected to the outside of the support sleeve 96.

[0025] The specific implementation process of this utility model is as follows: During use, the support plate 3 is rotated according to the device's operating state, allowing the patient to use it standing or sitting depending on their physical condition. The device's operating state can be adjusted according to usage needs. Then, the bidirectional screw 43 is rotated, causing the slide rod 41 to move in a threaded motion, thereby adjusting the distance between the two support rods 42. This allows the device to provide protection during use and prevent tipping. The device is then adjusted according to the patient's condition. The winding machine 6 is started to adjust the height of the end of the suspension rope 7. After adjustment, the limit pin 8 and the bracket 5 are manually rotated in a threaded motion, thereby adjusting the height of the end of the limit pin 8. When the arm comes into contact with the suspension rope 7, the rope 7 is pressed and limited within the support 5. Then, the patient manually grasps the handle 98 and pulls it down, causing the support sleeve 96 to slide within the guide rail 95 when the arm is extended. At this time, the guide rail 95 moves down, driving the slide cylinder 92 to move. The slide cylinder 92 slides outside the suspension rod 91, thereby compressing the spring 94. By raising and lowering the end of the suspension rope 7, the height of the guide rail 95 can be adjusted. And by the support sleeve 96 sliding within the guide rail 95, the device can be used to perform strength training on the arms of patients of different heights and conditions, improving the recovery effect of stroke patients.
