[0030] like Figure 1-5 As shown, the present embodiment proposes an improved wrist and finger rehabilitation board, including a support plate 1 and a slide groove 2, the support plate 1 is provided with a slide groove 2, a slider 3 is connected with a limited sliding connection in the slide groove 2, a spring 4 is fixedly connected in the slider 3, the other end of the spring 4 is fixedly connected with a limit plate 5, a pull rod 6 is fixedly connected to the limit plate 5, a clamping block 7 is fixedly connected to the pull rod 6, a wrist support plate 8 is fixedly connected to the slider 3, a wrist strap 9 is arranged on the wrist support plate 8, a palm support plate 10 is rotatably connected to the support plate 1, a finger support plate 11 is rotatably connected to the palm support plate 10, a finger separation groove 12 is provided on the finger support plate 11, a finger separation block 13 is fixedly connected to the finger support plate 11, a palm support support rod 14 is fixedly connected to the palm support plate 10, a finger support support rod 15 is fixedly connected to the finger support plate 11, and a palm support groove 16 is provided on the support plate 1. Embodiment 2:

[0031] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0032] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the cross-section of the slider 3 is "T"-shaped, and the side end face of the limiting plate 5 is fitted with the inner side face of the slider 3, which can ensure that the "T"-shaped slider 3 can slide smoothly in the slide groove 2 within a limited position.

[0033] like Figure 3 As shown, as a preferred implementation, on the basis of the above method, further, the pull rod 6 is fixedly connected to the central part of one side of the limit plate 5, and the clamping blocks 7 are symmetrically distributed on the left and right sides of the pull rod 6, which can ensure that the clamping blocks 7 on both sides can stably fix and limit the pull rod 6.

[0034] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, the finger grooves 12 are evenly distributed on the finger support plate 11, and the finger grooves 12 correspond to the finger blocks 13 one by one, which can ensure that multiple finger grooves 12 and finger blocks 13 can be used to facilitate the placement of the patient's fingers.

[0035] like Figure 5 As shown, as a preferred implementation, based on the above method, further, the palm rest support rods 14 are symmetrically distributed on the left and right sides of the palm rest 10, and the palm rest support rods 14 correspond to the palm rest grooves 16 one by one, which can ensure that the palm rest support rods 14 on both sides can stably support and fix the palm rest 10.

[0036] like Figure 2As shown, as a preferred embodiment, on the basis of the above method, further, a finger rest groove 17 is opened on the support plate 1, and a limiting block 18 is fixedly connected to the palm rest groove 16 and the finger rest groove 17, and the limiting blocks 18 are equidistantly distributed in the palm rest groove 16 and the finger rest groove 17, which can ensure that multiple limiting blocks 18 can conveniently fix the position after the angle is adjusted.

[0037] Specifically, when using the improved wrist and finger rehabilitation board: Figure 1-5 When using the device, the wrist can be placed on the wrist support plate 8, and then the wrist strap 9 on the wrist support plate 8 can be used to fix the hand on the wrist support plate 8 for limiting the position, and then the palm can be attached to the palm support plate 10, and the fingers can be placed and supported on the finger support plate 11 at intervals under the action of the finger separation groove 12 and the finger separation block 13, and the wrist joint dorsiflexion and metacarpophalangeal joint flexion can be achieved at the same time, so as to perform rehabilitation training. If the patients are different and the wrist lengths are different, when the placement position of the wrist support plate 8 needs to be adjusted, the pull rod 6 can be pulled, and the pull rod 6 drives the limit plate 5 to move, and the limit plate 5 can squeeze the spring 4 in the slider 3 when moving, and the pull rod 6 can move the block 7 out of the support plate 1. After the block 7 is moved out, the slider 3 can move in the slide groove 2 without hindrance, and the slider 3 can drive the wrist support plate 8 to move and adjust. After adjusting the use distance, release the pull rod 6, and the limit plate 5 and the pull rod 6 are driven to reset under the push of the spring 4. At the same time, the block 7 on the pull rod 6 can be engaged in the support plate 1, and the slider 3 and the wrist support plate 8 are limited and fixed, so that the use position of the wrist support plate 8 can be adjusted according to the use situation.

[0038] After the adjustment is completed, if the angle of the user's palm and fingers is increased, it is easy to cause excessive stretching of the palm flexor tendon and cause re-injury. When the use angles of the palm rest 10 and the finger rest 11 need to be adjusted separately, the palm rest support rod 14 on the palm rest 10 can be moved in the palm rest groove 16 to adjust the angle of the palm rest 10. After the adjustment is completed, the palm rest support rod 14 can be engaged with the limit block 18 for limit support. When adjusting the inclination angle of the finger rest 11, the finger rest support rod 15 can be moved in the finger support groove 17 to adjust the angle of the finger rest 11, and fixed on the limit block 18 in the finger support groove 17, which is convenient for adjustment according to the different injuries of the patient to avoid causing re-injury.

[0039] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the utility model; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the utility model.
