[0007] Preferably, the diameter of the sliding hole is consistent with the diameter of the sliding column, and a plurality of groups of fastening strips are arranged on the inner circumference of the sliding hole.

[0008] Preferably, the connecting belt is a soft belt that can be bent and folded.

[0009] Preferably, a hand rest is fixedly connected to one side of the bracket, and a through cavity is formed between the hand rest and the bracket.

[0010] Preferably, the connecting plate and the slot plate are perpendicular to each other.

[0011] Preferably, the two groups of inner sliding plates are located on the inner sides of the two groups of groove plates.

[0012] Preferably, the shapes of the inner and outer slide grooves are both bilateral wavy, the diameters of the short slide rod and the long slide rod are consistent, the diameter of the short slide rod is consistent with the size of the trough position of the wavy inner slide groove, and the diameter of the long slide rod is consistent with the size of the trough position of the wavy outer slide groove.

[0013] Preferably, one side of the long sliding rod is fixedly connected with a threaded barrel, one side of the short sliding rod is fixedly connected with a threaded rod, and the threaded barrel and the threaded rod are threadedly connected.

[0014] Preferably, threads are arranged on the outer sides of one end of the long sliding rod and the short sliding rod, and fixing nuts are threadedly connected at the threaded ends of the long sliding rod and the short sliding rod.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The device can adapt to the use of patients of different body shapes. The auxiliary support is pulled to slide along the sliding column. By changing the distance between the protective gear and the auxiliary support, it can be adapted to different arm lengths. A plurality of sets of fastening strips are arranged inside the sliding hole at the bottom of the auxiliary support, which can apply resistance to the sliding of the auxiliary support, so that the auxiliary support cannot be easily moved, thereby playing the role of fixing the auxiliary support. A hand rest is fixedly connected to one side of the support, and a through cavity is formed between the hand rest and the support. The arm is inserted into the opening of the protective gear and the auxiliary support, the wrist is placed on the support, the palm passes through the through cavity formed between the hand rest and the support, and hooks the hand rest.

[0017] 2. At each stage of the wrist rehabilitation process, the bending angle of the wrist joint needs to be adjusted to adapt to the specific needs of the patient's rehabilitation. Pulling the short slide bar can make the short slide bar slide along the inner slide groove, and pulling the long slide bar can make the long slide bar slide along the outer slide groove, so that the inclination angle and position of the support member change. Then tighten the fixing bolts at the ends of the long slide bar and the short slide bar so that the support member is clamped and fixed between the brace and the bracket. The inclination angle of the bracket can be changed, which plays a role in adjusting the bending angle of the wrist joint. The bilateral wavy inner and outer slide grooves increase the resistance to the movement of the long and short slide bars and improve the stability of the support member fixation. When encountering the problem of adjusting the angle between the brace and the bracket, but the length of the support member is not enough to reach the predetermined angle, the support member can be taken out, and the threaded barrel and threaded rod in the support member can be twisted to extend the distance that the threaded rod extends out of the threaded barrel, thereby making the length of the support member longer.

The device can adapt to the use of patients with different body shapes, and the auxiliary bracket 12 is pulled It is made to slide along the slide column 11, and the distance between the protective gear 1 and the auxiliary support 12 is changed to adapt to different arm lengths. A plurality of sets of fastening strips 122 are arranged inside the sliding hole 121 at the bottom of the auxiliary support 12, which can apply resistance to the sliding of the auxiliary support 12, so that the auxiliary support 12 cannot be easily moved, thereby playing the role of fixing the auxiliary support 12. A hand rest 22 is fixedly connected to one side of the bracket 2, and a through cavity is formed between the hand rest 22 and the bracket 2. The arm is inserted into the opening of the protective gear 1 and the auxiliary support 12, the wrist is placed on the bracket 2, and the palm passes through the through cavity formed between the hand rest 22 and the bracket 2, and the hand rest 22 is hooked.

[0026] The protective gear 1, the auxiliary support 12, the hand support 22, the inner slide plate 23 and the strip plate 3 are all made by 3D printing technology.

[0027] One end of the bracket 2 is fixedly connected to a connecting belt 21, which is a flexible and foldable soft belt. The bracket 2 is rotatably connected to one side of the protective gear 1 through the connecting belt 21. The flexible and foldable soft belt makes the brace more flexible during use, and the position and angle of the bracket 2 can be adjusted more conveniently.
