[0002] Rheumatoid arthritis is a chronic systemic disease of unknown cause. Common symptoms include inflammation of the small joints of the hands and feet, accompanied by pain. In severe cases, it can lead to joint deformities and loss of function. This disease is not easily treated surgically, and symptoms are usually relieved through rehabilitation exercises and medication.

[0003] Because existing rehabilitation devices for rheumatoid arthritis are bulky and expensive, they are not suitable for patients to use at home. Therefore, people have designed devices that incorporate suction cups, elastic stretching bands, and straight bars to allow patients to sit in a chair and train, making it easier for them to perform rehabilitation exercises at home. For example, Chinese utility model patent with publication number CN216366514U discloses a lower limb rehabilitation exercise device for rheumatoid arthritis.

[0004] However, in actual use, people have found that the above-mentioned rehabilitation exercise device has a problem: since the straight bar is fitted on a soft rubber sleeve, when people press the straight bar on their legs, the patient's legs may shake involuntarily. The surface of the straight bar is relatively smooth, and it may tilt with the shaking, causing the straight bar to slip off the legs. The device is unstable and inconvenient for patients to use. Utility Model Content

A clamping plate 16 is fixedly connected to the rotating component 15.

[0024] In this invention, the suction cup 1 is fixedly connected to two pedals 2 on both sides, and the pedals 2 are symmetrically arranged on both sides of the screw 3.

[0025] More specifically, by setting pedals 2 on both sides of suction cup 1, people can place their feet on pedals 2, which facilitates support for people's feet.

[0026] In this utility model, a connecting hole 9 is provided on the side of the sleeve 4 away from the stretching band 5. The connecting hole 9 is threaded inside, and the screw 3 is threadedly connected to the connecting hole 9.

[0027] More specifically, by opening a threaded connecting hole 9 on the sleeve 4, the height of the tension belt 5 can be adjusted to accommodate different height requirements.

[0028] In this utility model, a limiting hole 10 is provided on one side of the rubber sleeve 6, the rotating shaft 12 is disposed inside the limiting hole 10, and the outer side of the connecting rod 7 is in contact with the inner wall of the rubber sleeve 6.

[0029] More specifically, by opening a limiting hole 10 on one side of the rubber sleeve 6 and connecting it to the rotating shaft 12, the connecting rod 7 and the crossbar 8 can be limited to prevent the connecting rod 7 and the crossbar 8 from shaking on the rubber sleeve 6.

[0030] In this utility model, the lead screw 13 and the transmission gear 18 are respectively arranged on both sides of the drive gear 17. Both the drive gear 17 and the transmission gear 18 have umbrella-shaped structures, and the transmission gear 18 meshes with the drive gear 17.

[0031] More specifically, by setting up a bevel gear for driving, the lead screw 13 can drive the clamp 16 to move, so that the clamp 16 can fix people's legs.

[0032] In this utility model, a gasket is connected to the inner side of the clamping plate 16, and the slider 14 and both sides of the clamping plate 16 are in contact with the inner wall of the slide groove 11.

Before connecting the connecting rod 7 and the rubber sleeve 6, people stretch the side of the rubber sleeve 6 with the limiting hole 10 so that the connecting rod 7 and the crossbar 8 can pass through the rubber sleeve 6. After the rotating shaft 12 is aligned with the limiting hole 10, the elasticity of the rubber sleeve 6 will cause the limiting hole 10 to automatically reset, thereby limiting the rotating shaft 12. At this time, the connecting rod 7 and the crossbar 8 will be stable inside the rubber sleeve 6. Then people sit on the chair. The person bends their legs and places them on the pedal 2. Then, according to their needs, they rotate the sleeve 4 to adjust the height of the screw 3 within the connecting hole 9. The crossbar 8 will then be positioned on the person's legs according to the height of the sleeve 4. Next, the person rotates the rotating part 15 on the slider 14, causing the clamp 16 to rotate on the slider 14 to be placed longitudinally. They then rotate the shaft 12 on the connecting rod 7, causing the drive gear 17 to drive the transmission gears 18 on both sides to rotate. The transmission gears 18 then drive the lead screw 13 to rotate, thereby controlling the slider 14 to move the clamp 16 closer to the person's legs until both sides of the legs are in contact with the stretching band 5 and the clamp 16, and then the recovery training can begin.
