[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 6 The present invention comprises a base plate 1, a rectangular containing shell 2 is provided at the upper end of the base plate 1, a rotating shaft 3 with left and right axial directions is rotatably connected on the right side wall of the containing shell 2, a plurality of rotating wheels 4 evenly distributed along the left and right directions are provided on the rotating shaft 3, a draw belt 5 is wound on the rotating wheel 4, a free end of the draw belt 5 passes through the containing shell 2 and is provided with an elastic sleeve 6, a slot 7 is provided at the left end of the rotating shaft 3, a plurality of key slots 8 connected with the slot 7 are provided at the left end of the rotating shaft 3, a fixed disk 9 is provided on the left side of the rotating shaft 3 in the containing shell 2, the fixed disk 9 can be rotated and moved left and right, a plurality of clutch columns 10 evenly distributed along its circumferential direction and left and right axial directions are rotatably connected on the fixed disk 9, the clutch column 10 can be inserted into the slot 7 and is provided with a plurality of insert keys 11 which can be inserted into the key slot 8, a fixing plate 12 is coaxially provided on the clutch column 10, a torsion spring 13 connected with the fixing plate 12 and the fixing disk 9 is mounted on the clutch column 10, and the torsion of the plurality of torsion springs 13 increases in sequence in a clockwise direction starting from the rearmost side.

[0014] In order to facilitate the rotation of the fixed disk 9, a connecting shaft 14 is coaxially provided at the left end of the fixed disk 9. The left end of the connecting shaft 14 passes through the accommodating shell 2 and is coaxially provided with a knob 15.

[0015] In order to limit the fixed plate 9 , a plurality of limiting holes 16 corresponding to the clutch columns 10 are opened at the left end of the accommodating shell 2 , and a limiting column 17 which can be inserted into the limiting hole 16 is provided at the right end of the knob 15 .

[0016] In order to facilitate the movement of the drawstring 5, a sliding groove is provided at the front end of the accommodating shell 2, and a plurality of drawstrings 5 ​​are located in the sliding groove.

[0017] In order to facilitate the support of the patient, a support block 18 located in front of the elastic sleeve 6 is provided at the upper end of the base plate 1 .

[0018] In order to prevent the drawstring 5 from falling off the rotating wheel 4, baffles are respectively provided at the left and right ends of the rotating wheel 4.

[0019] When the utility model is in use, first place the base plate 1 on the table, then place the hand on the side to be exercised on the base plate 1, so that the four fingers except the thumb are respectively inserted into the corresponding elastic sleeves 6, and then the palm and thumb are placed on the supporting block 18. At this time, the four fingers pull the elastic sleeve 6 forward with force, and the elastic sleeve 6 drives the rotating wheel 4 to rotate through the drawstring 5, and the rotating wheel 4 drives the rotating shaft 3 to rotate. At this time, the rotating shaft 3 drives the clutch column 10 on the fixed plate 9 to rotate, and drives the torsion spring 13 to twist. Due to the restoring force of the torsion spring 13, the patient needs to use force to move the elastic sleeve 6 forward, thereby achieving the purpose of resistance training for the patient's fingers. After pulling forward for a distance, stop exerting force. Due to the action of the torsion spring 13, the rotating shaft 3 is reversed and the drawstring 5 is rewound around the rotating wheel 4, driving the elastic sleeve 6 to move backward to the initial position, and then it is pulled forward again and released. Repeatedly, the purpose of hand rehabilitation training can be achieved.

[0020] When it is necessary to adjust the training intensity, the knob 15 is pulled to the left, and the knob 15 drives the limit column 17 to move to the left and be pulled out from the corresponding limit hole 16, and at the same time drives the fixed plate 9 and the clutch column 10 thereon to move to the left. After the clutch column 10 at the rear side moves a distance to the left, the key 11 is pulled out from the key slot 8, and at the same time, the clutch column 10 at the rear side is pulled out from the slot 7. At this time, the knob 15 is turned clockwise to make the clutch column 10 originally located at the lower side located to the left of the rotating shaft 3, and then the knob 15 is pushed to the right. 15 drives the corresponding clutch column 10 to slide rightward and insert into the slot 7, and the key 11 is inserted into the key slot 8 to achieve connection, and at the same time, the limit column 17 is inserted into the corresponding limit hole 16 to re-fix and limit, preventing the fixed plate 9 from rotating. Since the torsion force of the torsion spring 13 originally located at the lower side is greater than the torsion spring 13 at the rear side, the restoring force of the torsion spring 13 received by the patient when pulling the elastic sleeve 6 forward again is greater than the torsion spring 13 originally at the rear side, so it needs to be pulled with more force, which achieves the purpose of increasing the intensity of exercise;

[0021] When the exercise intensity needs to be increased again, the knob 15 is pulled to the left again and rotated to connect the clutch column 10 originally located on the front side with the rotating shaft 3. At this time, the torsion force of the torsion spring 13 is greater, so the patient needs to use greater force to pull the elastic sleeve 6, thereby increasing the exercise intensity again.

[0022] Compared with the prior art, the beneficial effects of the utility model are: the bottom plate, containing shell, drawstring, elastic sleeve, etc. can achieve the purpose of hand rehabilitation training for patients with cerebral infarction, enhance hand flexibility and muscle strength, and at the same time can quickly adjust the training intensity according to the different conditions of the patients to make targeted training. This structure is simple, novel in conception, easy to use and highly practical.
