[0007] In some embodiments, the ring seat is provided with a fixedly connected connecting protrusion, and the ring connecting piece is provided with a connecting groove matching the shape of the connecting protrusion. The connecting protrusion slides within the connecting groove, and the axial direction of the movable groove is consistent with the axial direction of the connecting protrusion.

[0008] In some embodiments, a movable gap is provided between the top end of the connecting protrusion and the top end of the connecting groove.

[0009] In some embodiments, a row of fixing grooves is respectively disposed on both sides of the connecting protrusion.

[0010] In some embodiments, the diameter of the compression spring is consistent with the aperture of the movement hole.

[0011] In some embodiments, the cross section of the connecting protrusion is T-shaped.

[0012] The beneficial effects of the utility model are:

[0013] The finger joint training ring structure can quickly adjust the position of the ring seat by setting an elastic part between the ring seat and the ring connector. The elastic part can limit the ring seat and can also overcome the elastic force by pushing the ring seat to quickly adjust the position of the ring and fine-tune the execution end to the patient, thereby increasing the convenience of operation for medical staff, greatly shortening the adjustment time, and improving product competitiveness.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-2 The utility model provides a technical solution: a finger joint training ring structure, comprising a finger ring seat 1 and a finger ring connector 2, the finger ring connector 2 is arranged above the finger ring seat 1, and an elastic part is arranged between the finger ring seat 1 and the finger ring connector 2.

[0019] The ring base 1 is provided with a movable groove 13 for placing a finger, the top of the ring base 1 is provided with a fixedly connected connecting protrusion 11, the ring connector 2 is provided with a connecting groove 21 that matches the shape of the connecting protrusion 11, the connecting protrusion 11 is limitedly slid in the connecting groove 21, and the connecting groove 21 limits the movement of the connecting protrusion 11 in the up and down directions. Specifically, the cross section of the connecting protrusion 11 is T-shaped. In order to adjust the distance between the ring base 1 and the ring connector 2, a movable gap is provided between the top of the connecting protrusion 11 and the top of the connecting groove 21, and the axial direction of the movable groove 13 is consistent with the axial direction of the connecting protrusion 11.

[0020] The top surface of the ring base 1 is provided with a fixing groove 12, which is a circular groove and is arranged on a plane. The end surface of the ring connector 2 facing the fixing groove 12 is provided with a moving hole 22, and an elastic part is arranged in the moving hole 22. The elastic part includes a compression spring 31 and a ball 32. One end of the compression spring 31 is connected to the top of the moving hole 22, and the other end is in contact with the ball 32. The diameter of the compression spring 31 is consistent with the aperture of the moving hole 22, which limits the movement and compression or extension direction of the compression spring 31. Most of the ball 32 is restricted in the moving hole 22, and a small part protrudes outside the moving hole 22 and is arranged in the fixing groove 12. A row of fixing grooves 12 are respectively arranged on both sides of the connecting protrusion 11, and there are 4 fixing grooves 12 arranged along the axial direction of the connecting protrusion 11. The number of the moving holes 22 and the elastic part is less than the number of the fixing grooves 12.

[0021] In actual use, adjacent finger ring seats 1 are connected via finger ring connectors 2, which is a prior art and will not be described in detail here. The technical solution of the utility model is mainly that the finger ring seat 1 can adapt to the position of the finger.

[0022] The working principle and use process of the utility model are as follows: when the finger ring seat 1 needs to be adjusted, the finger ring seat 1 is pushed to overcome the elastic force of the compression spring 31, so that the ball 32 is separated from the original fixing groove 12, and the finger ring seat 1 slides axially along the connecting groove 21. When the finger ring seat 1 slides to a suitable position, the ball 32 is reconnected with the fixing groove 12 to complete the adjustment. During use, due to the connection between the ball 32 and the fixing groove 12, the finger ring seat 1 will not move at will.

[0023] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
