[0018] The embodiments of the utility model will be described in detail below, the example of the embodiment is shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as the limitation of the utility model.

[0019] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the utility model discloses a finger gripping strength rehabilitation training device, including fixed plate 2, center column 12 and a plurality of capsule 3, the center of fixed plate 2 is equipped with screw hole, and one end of center column 12 is installed with stud 8, and the other end of stud 8 is connected in screw hole, and the outside of center column 12 is sequentially connected with different size outer sleeve 1, a plurality of capsule 3 are evenly arranged in the outside of center column 12 and are in annular structure, and capsule 3, center column 12 and outer sleeve 1 are combined to form the gripping strength training device of cylindrical structure, and a plurality of connecting grooves 9 are arranged on the side of fixed plate 2 towards center column 12 and are in annular structure, one end of capsule 3 is installed with connecting block 11, and connecting block 11 is slidably arranged in connecting groove 9.

[0020] In the embodiment, the outside of fixed plate 2 is formed with positioning part 7 in annular structure, and fixed plate 2 is threadedly connected with blocking ring 6 outside, one side of blocking ring 6 is arranged in abutment with positioning part 7, one end of connecting block 11 is installed with compression spring 5, and the other end of compression spring 5 is arranged in abutment with the inner ring surface of blocking ring 6.

[0021] In the embodiment, the inner ring surface of outer sleeve 1 is provided with limiting groove 4 opposite to capsule 3, and the outer ring surface of capsule 3 is formed with limiting part 10 opposite to limiting groove 4, and limiting part 10 is inserted into limiting groove 4.

[0022] In the embodiment, the inner ring surface of outer sleeve 1 is provided with limiting groove 4 opposite to capsule 3, and the outer ring surface of capsule 3 is formed with limiting part 10 opposite to limiting groove 4, and limiting part 10 is inserted into limiting groove 4.

[0023] In the embodiment, capsule 3 is in cylindrical structure, and is made of rubber material, and the inside of capsule 3 is filled with air, and the fingers can be squeezed inward to achieve the effect of rehabilitation training after holding the plurality of capsules.

[0024] In the embodiment, center column 12, outer sleeve 1 and fixed plate 2 are made of plastic material, so that the cost and weight are reduced.

[0025] In the embodiment, the inner wall surface of limiting groove 4 is provided with anti-skid lines, and the anti-skid lines are arranged in abutment with limiting part 10, the friction between limiting part and limiting groove is increased through the anti-skid lines, the capsule can be positioned through limiting part and limiting groove, and the swinging of the capsule is avoided.
