[0047] A method for using a finger rehabilitation training corrector. Using the above-mentioned finger rehabilitation training corrector, the steps of use are as follows:

[0048] S1. Installation: fit the arm guard 1 to the patient's wrist, fix the arm guard 1 to the patient's wrist using the Velcro at the lower part of the arm guard 1, and then insert the patient's fingers into the first finger sleeve 6, the second finger sleeve 8 and the thumb sleeve 1004 accordingly;

[0049] S2. Adjustment: The adjustment component can be driven to operate by rotating the threaded rod 701, thereby adjusting the stretching degree of the spiral spring 705, so as to achieve the effect of adjusting according to the palm strength of the patient;

[0050] S3, opening and closing training: By turning the knob 501, the opening and closing assembly can be driven to operate, and then the first finger sleeve 6 can be pulled to open and close to both sides through the straight rod 505, so as to achieve the effect of training the patient's finger opening and closing ability:

[0051] S4. Grip training: The patient can drive the second finger sleeve 8 to converge to the palm by clenching his fist, and use the elastic force of the spiral spring 705 to stretch to achieve the effect of grip training. In addition, the second finger sleeve 8 can be stretched by rotating the rotating rod 903 to achieve auxiliary grip training.

[0052] The technical solution provided by the present invention is to fix the arm guard 1 on the patient's arm, insert the patient's fingers into the first finger sleeve 6, the second finger sleeve 8 and the thumb sleeve 1004 respectively, use the separation and combination component to perform opening and closing training on the patient's fingers to assist the patient in opening and closing, use the stretching component to perform bending training on the fingers, use the adjustment component to adjust the stretching degree of the coil spring 705 according to the palm strength of the patient, and use the conversion component to realize the left and right position conversion of the thumb sleeve 1004 to realize the conversion of the left and right hands of the patient. Specifically, after the training is installed on the patient's hand, the conversion component is used to convert the left and right hands of the patient. The rotating knob 501 can drive the elliptical plate 502 to rotate. During the rotation of the elliptical plate 502, the push plate 503 will be pushed to move away from the elliptical plate 502. The push plate 503 drives the slider 507 to slide in the slide groove 508 and stretch the compression spring 509. At the same time, the movement of the push plate 503 will push the push rod 504 to rotate around the connection with the push plate 503, and then the push rod 504 will push the straight rod 505 to slide in the strip groove 506, and then drive the first finger sleeve 6 to move outward, so as to achieve the purpose of opening and closing the patient's fingers and assist the patient in opening and closing training.

[0053] When the patient is doing grip training, the palm of the hand makes a fist movement, which will pull the second finger sleeve 8 to gather towards the palm. During the movement of the second finger sleeve 8, the coil spring 705 will be stretched, and the training is achieved through the elastic force of the coil spring 705. Since the strength of the patient's palm is different in different recovery periods, it is necessary to adjust the elastic force of the coil spring 705. At this time, the threaded rod 701 is rotated, and the threaded rod 701 rotates to move downward, which will push the bottom plate 706 to move downward. During the movement of the bottom plate 706, the tilting rod 707 is driven to rotate around the support 708. The end of the tilting rod 707 away from the bottom plate 706 moves upward, which will push the folding rod 703 to move upward. During the upward movement of the folding rod 703, the round rod 704 will be pulled upward through the strip plate 702, and then the threaded spring will be stretched, thereby achieving the effect of adjusting the stretching degree of the threaded spring, and achieving the purpose of adjusting the stretching force of the trainer according to the patient's grip strength.

[0054] If the patient needs to train his grip strength, the rotating rod 903 can be rotated to drive the spring spring 906 to contract and the winding shaft 904 to rotate. During the rotation of the winding shaft 904, the rope 905 will be wound up, and then the second finger sleeve 8 will be pulled toward the palm through the rope 905. Then, the rotating rod 903 is loosened, and the rebound of the spring spring 906 will drive the winding shaft 904 to rotate in the opposite direction, and then the rope 905 will be released. In this way, the purpose of grip strength training for the patient's fingers can be achieved. When wearing the thumb sleeve 1004, the patient's thumb sleeve 1004 is arranged in the thumb sleeve 1004. By moving the ring 1001 upward, the positioning block 1005 can be driven to slide out of the positioning groove 1006. Then, the ring 1001 is rotated 180 degrees to make the extension rod 1002 rotate to the other side of the back plate 2, and then the ring 1001 is pushed downward to make the positioning block 1005 snap into the positioning groove 1006 on the corresponding side, thereby achieving the effect of adjusting the position of the thumb sleeve 1004 and realizing the switching of the left and right hands.

A finger rehabilitation training corrector according to claim 5, characterized in that: The conversion assembly comprises a circular ring (1001) movably mounted on the outer surface of the support rod (3); an extension rod (1002) is fixedly connected to the outer surface of the circular ring (1001); a connecting rod (1003) is movably connected to the upper portion of one end of the extension rod (1002) away from the circular ring (1001); and a thumb sleeve (1004) is provided at the lower portion of one end of the connecting rod (1003) away from the extension rod (1002).

7. A finger rehabilitation training corrector according to claim 6, characterized in that: A positioning block (1005) is fixedly connected to the lower surface of one end of the extension rod (1002) away from the ring (1001), and a positioning groove (1006) is formed through the upper surface of the back plate (2), and the positioning block (1005) is snap-fitted into the positioning groove (1006).

8. A method for using a finger rehabilitation training corrector, using the finger rehabilitation training corrector as claimed in claim 7, the using steps are as follows: S1. Installation: fit the arm guard (1) to the patient's wrist, and fix the arm guard (1) to the patient's wrist using the Velcro at the bottom of the arm guard (1), and then insert the patient's fingers into the first finger sleeve (6), the second finger sleeve (8), and the thumb sleeve (1004) accordingly; S2, adjustment: by rotating the threaded rod (701), the adjustment component can be driven to operate, thereby adjusting the stretching degree of the spiral spring (705), so as to achieve the effect of adjusting according to the palm strength of the patient; S3, opening and closing training: by turning the knob (501), the opening and closing assembly can be driven to operate, and then the first finger sleeve (6) can be pulled to open and close to both sides through the straight rod (505), so as to achieve the effect of training the patient's finger opening and closing ability: S4. Grip strength training: The patient can drive the second finger sleeve (8) to converge towards the palm by voluntarily making a fist, and utilize the elastic force of the spiral spring (705) to stretch to achieve the effect of training grip strength. In addition, the second finger sleeve (8) can be stretched by rotating the rotating rod (903) to drive the stretching component to run, thereby achieving auxiliary grip strength training.
