It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0025] As attached Figures 1 to 7 The finger flexion and extension training rehabilitation device shown includes: a wristband 1, with a connecting strap a11 fixedly connected to the top of the wristband 1 and a connecting strap b12 fixedly connected to one side of the wristband 1, and a swivel buckle 13 provided in the connecting strap b12; and a flexion and extension training mechanism, which is provided on the swivel buckle 13 and is used for finger flexion and extension training.

[0026] Specifically: When performing finger flexion and extension rehabilitation training, the wristband 1 is worn on the wrist of the trainee, and the connecting strap b12 is connected to the sun-shaped mounting buckle 13. Finger flexion and extension rehabilitation training is performed through the flexion and extension training mechanism. The flexion and extension distance can be adjusted according to the finger being trained, thereby adapting to the training of different fingers and improving practicality.

[0027] In a preferred embodiment, the connecting strap a11 is provided with a D-shaped adjustment buckle 4, the bottom end of the wrist strap 1 is fixedly connected with an edge end 41, the front side of the wrist strap 1 is fixedly connected with a Velcro a5 near the bottom, and the back side of the wrist strap 1 is fixedly connected with a Velcro b51.

[0028] Furthermore, when wearing the wristband 1, one end of the edge 41 is passed through the D-shaped adjustment buckle 4 to make the wristband 1 into a ring structure. Then, the hand is passed through the ring structure of the wristband 1, and the edge 41 is pulled to tighten the ring structure of the wristband 1. Then, the Velcro a5 is attached to the Velcro b51. The Velcro b51 has a rough side, and the Velcro a5 has a hook side. Example 2

[0029] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 7 As shown below, see details:

[0030] The flexion and extension training mechanism includes: a fixed cylinder 2, a movable cylinder 21, a spring 22, a through hole 23, and an elastic rope 24. Multiple fixed cylinders 2 are fixedly installed inside the D-shaped mounting buckle 13. Movable cylinders 21 are slidably connected inside each fixed cylinder 2. A spring 22 is connected between one end of the fixed cylinder 2 and the opposite end of the movable cylinder 21. Through holes 23 are opened on both the fixed cylinder 2 and the movable cylinder 21. An elastic rope 24 is installed inside the through hole 23. A limit ball 25 is fixedly connected to one end of the elastic rope 24, and a finger sleeve 26 is fixedly connected to the other end of the elastic rope 24.

[0031] In use, the movable cylinder 21 is pressed into the fixed cylinder 2. The movable cylinder 21 moves and compresses the spring 22 to compress and store energy until the through hole 23 on the fixed cylinder 2 and the movable cylinder 21 are aligned. The size of the aligned through hole 23 is larger than the size of the limiting ball 25. At this time, one end of the limiting ball 25 is passed through the through hole 23 on the fixed cylinder 2 and the movable cylinder 21, so that the elastic rope 24 is located in the through hole 23. Then, the movable cylinder 21 is released, and the spring 22 releases its elasticity to push the movable cylinder 21 out of the fixed cylinder 2. At this time, the through hole 23 on the movable cylinder 21 and the fixed cylinder 2 are misaligned, clamping the elastic rope 24. The inner wall of the through hole 23 is provided with anti-slip texture to increase the friction between it and the elastic rope 24, so that the elastic rope 24 is clamped and fixed to prevent it from being pulled and moved. When adjusting the finger flexion and extension distance, the movable cylinder 21 is pressed to release the fixation of the elastic rope 24. Then, the length of the elastic rope 24 is manually adjusted to adjust the finger flexion and extension distance as needed.

[0032] In a preferred embodiment, a limiting ring 3 is fixedly connected to the inner wall of the fixed cylinder 2, the movable cylinder 21 is located inside the limiting ring 3, and multiple guide rails 31 are fixedly connected to the outside of the movable cylinder 21. A through hole 32 is provided on one side of the H-shaped mounting buckle 13 to allow the movable cylinder 21 to pass through.

[0033] Furthermore, when the movable cylinder 21 is pressed, the movable cylinder 21 moves inside the through hole 32. The movable cylinder 21 is guided by multiple guide rails 31, so that the movable cylinder 21 can only move along the horizontal direction of the guide rails 31. The limiting ring 3 can limit the movement distance of the movable cylinder 21 and prevent the movable cylinder 21 from moving out of the fixed cylinder 2.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
