[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-Figure 4As shown, the present invention provides a modular finger strength rehabilitation assessment system, comprising: a processing module 1, the top of the processing module 1 is fixedly connected to a test assembly 2; a test assembly 2, the test assembly 2 comprises a fixed block 201, the bottom of the fixed block 201 is fixedly connected to the top of the processing module 1, the rear surface of the fixed block 201 is fixedly connected to a motor 202, the output end of the motor 202 rotates through the rear surface of the fixed block 201, the output end of the motor 202 is fixedly connected to a threaded rod 203, the outer surface of the threaded rod 203 is threadedly connected to an adjustment block 204, the inner surface of the adjustment block 204 is fixedly connected to a sliding sleeve 205, the inner surface of the sliding sleeve 205 is slidably connected to a pull rod 206, the outer surface of the pull rod 206 is provided with a spring 207, the front end surface of the pull rod 206 is provided with a pull block 212, and the rear end surface of the pull rod 206 is fixedly connected to a first round block 208. The rear end face of the first round block 208 is equidistantly fixedly connected with a plurality of mounting rods 209, and the rear end faces of the plurality of retractable mounting rods 209 are all fixedly connected with the second round block 211. A pressure sensor 210 is arranged at the center of the front end face of the second round block 211. The spring 207 is located between the first round block 208 and the sliding sleeve 205. The spring 207 and the sliding sleeve 205 are matched with each other. The plurality of mounting rods 209 are all located at the edge of the front end face of the second round block 211. The outer surfaces of the plurality of mounting rods 209 all slide through the rear surface of the fixed block 201. A support plate 217 is fixedly connected to the top of the fixed block 201 near the front surface. The inner surface of the support plate 217 is rotatably connected to the outer surface of the threaded rod 203 near the rear end face. A sliding rod 216 is fixedly connected between the support plate 217 and the fixed block 201. The outer surface of the sliding rod 216 is slidably connected to the inner surface of the adjustment block 204.

[0023] The effect achieved by the entire embodiment 1 is that, when evaluating the rehabilitation of finger strength, a multi-stage evaluation is required. First, the finger that needs to be tested for strength is bent and inserted into the pull block 212 and pulled forward. When the pull rod 206 slides forward on the inner surface of the sleeve 205, the front end surface of the first round block 208 will squeeze the spring 207, causing it to deform and shrink between the first round block 208 and the sleeve 205. At the same time, the finger needs to withstand the elastic reset force of the spring 207, and with continuous pulling, multiple mounting rods 209 slide on the inner wall of the fixed block 201, so that the front end of the pressure sensor 210 provided on the front end surface of the second round block 211 contacts the rear surface of the fixed block 201, triggering the pressure sensor 210 so that the pressure value it receives is recorded and displayed by the display module provided on the front side of the processing module 1, and the pull block 2 is released. 12 is pulled, so that the pull rod 206 is reset under the elastic reset action of the spring 207, and then the motor 202 is started. When the output end of the motor 202 drives the threaded rod 203 to rotate in the inner wall of the support plate 217, the adjustment block 204 threadedly connected thereto slides backward along the outer surface of the slide rod 216, driving the rear end face of the sleeve 205 to resist the spring 207, causing it to gradually shrink between the first round block 208 and the sleeve 205, resulting in a smaller gap between the springs of the spring 207, so that the elasticity of the spring 207 gradually increases, increasing the resistance when the person pulls the pull rod 206, facilitating the recovery of the fingers of the person, and being tested under different pulling forces. The finger strength test data is transmitted to the processing module 1 under the action of the electrical connection, and the processing module 1 compares and evaluates the collected data.

[0024] Example 2, as Figure 1-Figure 4 As shown, a protective cover 213 is provided on the inner surface of the pull block 212, and a connecting rod 214 is fixedly connected to the rear surface of the pull block 212. The outer surface of the connecting rod 214 is rotatably connected to the inner surface of the pull rod 206. The rear end face of the connecting rod 214 is fixedly connected to a limiting block 215, and the outer surface of the limiting block 215 is rotatably connected to the inner surface of the pull rod 206.

[0025] The effect achieved by the entire embodiment 2 is that, when in use, a connecting rod 214 is fixedly set on the rear end face of the pull block 212, and the connecting rod 214 rotates on the inner surface of the pull rod 206 through the limit block 215, so that the pull block 212 can be transformed into a vertical state, which is convenient for people to use. A protective cover 213 is set on the inner surface of the pull block 212, and the protective cover 213 is made of rubber, so that a buffer can be provided between the fingers of the person and the pull block 212, which has a protective effect and is highly practical.

[0026] Working principle: When evaluating finger strength rehabilitation, a multi-stage evaluation is required. First, bend the finger that needs strength testing and insert it into the pull block 212 and pull it forward. When the pull rod 206 slides forward on the inner surface of the sleeve 205, the front end surface of the first round block 208 will squeeze the spring 207, causing it to deform and shrink between the first round block 208 and the sleeve 205. At the same time, the finger needs to withstand the elastic reset force of the spring 207, and with continuous pulling, multiple mounting rods 209 slide on the inner wall of the fixed block 201, so that the front end of the pressure sensor 210 provided on the front end surface of the second round block 211 abuts against the rear surface of the fixed block 201, triggering the pressure sensor 210 so that the pressure value it receives is recorded and displayed by the display module provided on the front side of the processing module 1. Release the pull on the pull block 212, so that it drives the pull rod 206 to reset under the elastic reset action of the spring 207, and then start the motor 202. The output end of the motor 202 drives the threaded rod 203 to rotate in the inner wall of the support plate 217, and The adjusting block 204, which is threadedly connected, slides backward along the outer surface of the sliding rod 216, driving the rear end surface of the sliding sleeve 205 to resist the spring 207, causing it to gradually contract between the first round block 208 and the sliding sleeve 205, resulting in a smaller gap between the springs 207 and the elasticity of the spring 207, thereby increasing the resistance when the person pulls the pull rod 206, facilitating the rehabilitation of the person's fingers. The test is conducted under different pulling forces, and the finger strength test data is transmitted to the processing module 1 under the action of the electrical connection. The processing module 1 compares and evaluates the collected data. By fixing a connecting rod 214 on the rear end surface of the pull block 212, the connecting rod 214 rotates on the inner surface of the pull rod 206 through a limit block 215, so that the pull block 212 can be turned into a vertical state, which is convenient for the person to use. By providing a protective cover 213 on the inner surface of the pull block 212, the protective cover 213 is made of rubber, which can provide a buffer between the person's fingers and the pull block 212, thereby achieving a protective effect and high practicality.
