For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1-5 As shown, the finger dexterity rehabilitation training aid proposed by the utility model acts on the finger dexterity rehabilitation training device 1. The finger dexterity rehabilitation training device 1 is composed of a main ring 11, an elastic band 12, and a finger sleeve 13. Five elastic bands 12 are arranged in a circular array along the main ring 11, and one end of the elastic band 12 away from the main ring 11 is fixedly connected to the finger sleeve 13. The finger dexterity rehabilitation training device 1 is a prior art and can be used for finger dexterity rehabilitation training. When in use, the five finger sleeves 13 are respectively put on the fingertips of the five fingers, and the five fingers can be opened and closed for exercise.

[0030] In this embodiment, the auxiliary device includes: a base box 2 as an installation base, a sinking mechanism 3 that bends the elastic band 12 to reduce the radial length, a support ring 4 and a spring 5 that provide upward support for the main ring 11, and a limiting assembly 6 that prevents the elastic band 12 from shifting.

[0031] Specifically, refer to Figure 3-5 , five first belt holes 21 are opened on the top of the bottom box 2, and the five elastic belts 12 are respectively placed in the corresponding first belt holes 21 for positioning;

[0032] refer to Figure 3-4 The sinking mechanism 3 includes a central column 31 and a pressure ring 32. The bottom end of the central column 31 is fixedly connected to the upper surface of the bottom plate of the bottom box 2. The total ring 11 is movably connected to the central column 31. The pressure ring 32 is located above the total ring 11 and is threadedly connected to the central column 31. When the pressure ring 32 is rotated, the pressure ring 32 moves downward by threading with the central column 31, thereby pushing the total ring 11 downward, causing the end of the elastic band 12 close to the total ring 11 to bend downward, thereby shortening the length of the elastic band 12 outside the auxiliary device, providing greater elastic resistance when the fingers are opened and closed, thereby increasing the training intensity. Users can increase the training intensity accordingly according to different rehabilitation stages or training stages to meet different rehabilitation training needs;

[0033] refer to Figure 3-4 The support ring 4 and the spring 5 are movably connected with the central column 31. The bottom end of the spring 5 abuts against the bottom plate of the bottom box 2, and the top end of the spring 5 abuts against the support ring 4. The elastic thrust of the spring 5 and the support of the support ring 4 can ensure that the total ring 11 will not slide down directly to the bottom at any height;

[0034] refer to Figure 3-4 The limiting assembly 6 includes a cover body 61 and a column sleeve 62. The column sleeve 62 is threadedly engaged with the top of the central column 31. Five second belt holes 611 that can be vertically aligned with the first belt hole 21 are provided at the bottom of the cover body 61. The top of the cover body 61 is sleeved on the outside of the column sleeve 62, and an annular protrusion is coaxially arranged on the outer annular surface of the column sleeve 62, and an annular groove is coaxially arranged on the inner annular surface of the top of the cover body 61. The rotational connection of the cover body 61 on the column sleeve 62 can be achieved by the coaxial rotation between the annular groove and the annular protrusion. When the column sleeve 62 is rotated, the column sleeve 62 moves downward by the threaded engagement with the central column 31, thereby driving the cover body 61 to move downward. The position of the cover body 61 is rotated to adjust the position so that the second belt holes 611 are aligned one by one with the first belt holes 21. When the cover body 61 moves down to the position shown in the figure, the elastic band 12 can be limited in the first belt hole 21;

[0035] In the above, the second belt hole 611 and the first belt hole 21 can be combined into a complete circular groove, and the diameter of the circular groove is slightly smaller than the diameter of the elastic band 12. When the cover body 61 is not completely moved down to contact with the top of the bottom box 2, the second belt hole 611 and the first belt hole 21 are not completely combined, and no squeezing force will be generated on the elastic band 12. Therefore, during training, the elastic band 12 will start to stretch from the part located in the bottom box 2. When the cover body 61 is completely moved down to contact with the top of the bottom box 2, that is, the second belt hole 611 and the first belt hole 21 are completely combined, the elastic band 12 will be squeezed tightly, and during training, the elastic band 12 will start to stretch from the squeezed part. Therefore, when the part of the elastic band 12 located in the bottom box 2, especially the connection with the total ring 11, is broken and damaged and cannot be used anymore, the stretching starting point of the elastic band 12 can be changed by the above operation, so that the finger dexterity rehabilitation trainer 1 can continue to be used.

[0036] The working principle of this embodiment is as follows: the finger dexterity rehabilitation trainer 1 is assembled with the bottom box 2. During assembly, the total ring 11 is first inserted from the top of the central column 31 and placed on the support ring 4. Then the pressure ring 32 is screwed in from the top of the central column 31. As the pressure ring 32 moves downward, it pushes the total ring 11 downward, causing the end of the elastic band 12 close to the total ring 11 to bend downward, so that the length of the elastic band 12 located outside the auxiliary device is shortened, which can provide greater elastic resistance when the fingers are opened and closed, thereby increasing the training intensity. Users can increase the training intensity accordingly according to different rehabilitation stages or training stages to meet different rehabilitation training needs.

[0037] Then, the column sleeve 62 is screwed and connected with the top thread of the central column 31. When the column sleeve 62 is rotated, the column sleeve 62 moves downward through the screw thread between the central column 31, thereby driving the cover 61 to move downward. The position of the cover 61 is adjusted by rotation so that the second belt hole 611 is aligned with the first belt hole 21 one by one. When the cover 61 moves down to the position shown in the figure, the elastic band 12 can be limited in the first belt hole 21. And as mentioned above, the starting point of the extension of the elastic band 12 can be changed by changing the downward movement distance of the cover 61, thereby extending the service life of the finger dexterity rehabilitation trainer 1.

[0038] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
