[0035] Working principle: When the hand exercise device is running, first put the wrist fixing ring 1 on the wrist. Then the patient holds the first pressing plate 3 and the second pressing plate 31 with the hand at the same time. Then, through the friction force between the first damping plate 23 and the inner fixing cover 14, the wrist is exercised. And through the spring 39, with the first pressing plate 3 as the stress point, the second pressing plate 31 is pushed outward to limit the hand strength of the patient. When it is necessary to adjust the damping force between the first damping plate 23 and the inner fixing cover 14, and between the second damping plate 35 and the damping rod 36 to adapt to the patient, only need to use the air pump 2 to deliver air into the first air bag 22 through the first air delivery pipe 21. Through the inflation of the first air bag 22, with the outer fixing cover 12 as the stress point, the first damping plate 23 is pushed inward, so as to increase the pressure between the first damping plate 23 and the inner fixing cover 14, thereby increasing the friction force between the first damping plate 23 and the inner fixing cover 14, and thus increasing the rotational damping force between the outer fixing cover 12 and the inner fixing cover 14. When it is necessary to adjust the gripping force between the first pressing plate 3 and the second pressing plate 31, control the second air delivery pipe 27 to make the first air delivery pipe 21 communicate with the second air delivery pipe 27. Then use the air pump 2 to deliver gas into the second air bags 33 on both sides through the first air delivery pipe 21, the second air delivery pipe 27, the first connecting pipe 29 and the second connecting pipe 210 at the same time. Then, with the guide sleeve 32 as the stress point, the second damping plate 35 is pushed inward through the second air bag 33, increasing the friction force between the second damping plate 35 and the damping rod 36 to increase the damping force between the second damping plate 35 and the damping rod 36.
