[0023] Embodiment

[0024] Please refer to Figures 1-4 , a hand grip rehabilitation device, including a first support plate 1. The top end of the first support plate 1 is fixedly installed with a pressing plate 3 through two springs 2. The top end of the pressing plate 3 is fixedly installed with a second support plate 5 through two connecting plates 4. A screw rod 6 is longitudinally installed at the top end of the first support plate 1. The screw rod 6 is located between the two springs 2. A through hole is provided in the middle area of the pressing plate 3. The screw rod 6 is located inside the through hole provided in the pressing plate 3. A rotating plate 7 is screwed on the screw rod 6. A limiting cylinder 8 is fixedly installed at the top end of the first support plate 1. The outer side wall of the pressing plate 3 is slidably connected with the inner side wall of the limiting cylinder 8. Both of the two springs 2 are located inside the limiting cylinder 8; A limiting plate 11 is fixedly installed at the top end of the screw rod 6. By installing the limiting plate 11, the top end of the rotating plate 7 during the rotating operation is limited. A handle 12 is fixedly installed on the outer side wall of the rotating plate 7. By installing the handle 12, it is convenient for the user to rotate the rotating plate 7.

[0025] Please refer to Figures 1-4 , the top end of the first support plate 1 is connected with the bottom end of the second support plate 5 through a limiting mechanism. The limiting mechanism includes a fixing plate 9. The fixing plate 9 is fixedly installed at the top end of the first support plate 1. Two limiting rods 10 are symmetrically and slidably connected to the top end of the fixing plate 9. Each limiting rod 10 is fixedly installed at the bottom end of the second support plate 5. By the sliding operation of the limiting rods 10 on the top end of the fixing plate 9, it is convenient to limit the second support plate 5 during the sliding operation. For this hand grip rehabilitation device, by rotating the rotating plate 7, the pressing plate 3 squeezes the spring 2, thereby adjusting the compression degree of the spring 2. By holding the second support plate 5 and the first support plate 1 by hand, the connecting plate 4 and the pressing plate 3 drive to squeeze the spring 2, thereby performing strength rehabilitation training on the patient's hand, facilitating the adjustment of the grip degree between the second support plate 5 and the first support plate 1 according to the grip requirements of different needs, thereby improving the usage range and usage effect of the device, facilitating the rehabilitation training of the hand strength of different patients, and improving the practicability.

[0026] Please refer to Figure 1 , limiting grooves 13 are provided at the top end of the second support plate 5 and the bottom end of the first support plate 1. By providing the limiting grooves 13, it is convenient for the user to hold the second support plate 5 and the first support plate 1.

[0027] Please refer to Figure 1 , a plurality of buffer pads 14 are fixedly installed on the outer side wall of the limiting cylinder 8. By installing the buffer pads 14, it is convenient for the user to closely hold the device.

[0028] In summary, when the hand grip rehabilitation device is in use, since the rotating plate 7 and the screw rod 6 are screwed, rotating the handle 12 will simultaneously drive the rotating plate 7 to rotate. While the rotating plate 7 rotates, it drives the pressing plate 3 to squeeze the two springs 2, so that the two springs 2 are compressed, and then the force of the compression of the springs 2 is adjusted. The user performs a grip force operation by holding the limiting grooves 13 provided on the first support plate 1 and the second support plate 5. After the acting force is transmitted to the connecting plate 4 and the pressing plate 3 through the second support plate 5, through the expansion and contraction of the springs 2, the hand of the patient can be rehabilitated for grip force training.
