[0020] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] Refer to the attached Figures 1-4, a finger flexibility auxiliary training device for a flute proposed by the present utility model, includes an operation ball 10, on which expansion top blocks 20 are symmetrically installed. An inclined groove 23 is formed on the outer wall of the expansion top block 20, and the outer wall of the expansion top block 20 is slidably connected to the inner wall of the installation groove 11; wherein, the two expansion top blocks 20 provided can press and separate two fingers, thereby performing bifurcation training on the fingers.

[0023] Two groups of elastic pressing components are arranged inside the installation groove 11, and the two groups of elastic pressing components are respectively used to press the two expansion top blocks 20. The elastic pressing component includes an adjusting plate 22 installed inside the installation groove 11. A spring 21 is fixedly installed on the outer wall of the adjusting plate 22, and one end of the spring 21 away from the adjusting plate 22 is fixedly connected to the outer wall of the expansion top block 20; wherein, when pressing the finger with the expansion top block 20, the spring 21 is provided here, and the spring 21 provides a certain buffering force for the expansion top block 20. For a trainer in the initial stage of training, it can avoid discomfort to the trainer's finger caused by hard extrusion.

[0024] An adjusting mechanism is arranged inside the installation groove 11, and the adjusting mechanism is used to adjust the position of the adjusting plate 22. The adjusting mechanism includes a bidirectional lead screw 36. The outer wall of the adjusting plate 22 is slidably connected to the inner wall of the installation groove 11. A threaded slider 37 is fixedly installed on the outer wall of the adjusting plate 22, and the two threaded sliders 37 are respectively threadedly connected to the outer wall of the bidirectional lead screw 36. A driving component is arranged on the operation ball 10, and the driving component is used to drive the bidirectional lead screw 36 to rotate. The driving component includes a rotating shaft 32 rotatably connected to the inner wall of the installation groove 11. A through groove 33 communicating with the inside of the installation groove 11 is formed on the top wall of the operation ball 10. The rotating shaft 32 passes through the through groove 33 and extends to the outside of the operation ball 10. A rotating wheel 31 is fixedly connected to the top end of the rotating shaft 32, and a driving bevel gear 34 is fixedly installed at the bottom end of the rotating shaft 32. A driven bevel gear 35 is fixedly installed on the outer wall of the bidirectional lead screw 36, and the driving bevel gear 34 meshes with the driven bevel gear 35; wherein, when the trainer performs bifurcation training for a long time, the position of the adjusting plate 22 can be adjusted here, thereby compressing the spring 21, making the elasticity of the spring 21 increase. At this time, the training intensity for the trainer can be improved, that is, when using this device to bifurcate two adjacent fingers, after adjusting the elasticity of the spring 21, the expansion top block 20 will not move easily, thereby enhancing the training intensity of the trainer;

[0025] Among them, when adjusting the compression of the spring 21, the rotary wheel 31 can be rotated. The rotary wheel 31 drives the rotation of the rotating shaft 32, and the rotating shaft 32 drives the rotation of the driving bevel gear 34. The driving bevel gear 34 meshes with the driven bevel gear 35, thereby driving the rotation of the driven bevel gear 35. The driven bevel gear 35 drives the rotation of the bidirectional lead screw 36. After the bidirectional lead screw 36 rotates, the threads on the outer wall of the bidirectional lead screw 36 mesh with the threads on the inner walls of the two threaded sliders 37 respectively, thereby driving the two threaded sliders 37 to move in the direction away from each other, and further driving the two adjusting plates 22 to move in the direction away from each other, so as to realize the compression of the spring 21. At this time, when the two fingers are bifurcated, the expansion top block 20 will not move easily after being squeezed, thereby realizing the enhancement of the training effect.

[0026] An installation hole 38 is formed in the end wall of the expansion top block 20; among them, the installation hole 38 is parallel to the bidirectional lead screw 36. When the expansion top block 20 moves, the bidirectional lead screw 36 can enter the interior of the installation hole 38, so that the bidirectional lead screw 36 does not block the movement of the expansion top block 20.

[0027] In this embodiment, the working principle of the device is as follows Figure 1 As shown in the figure, when using the device for the bifurcation training of the fingers, the thumb and index finger of one hand can be used to pinch the operation ball 10, and then the operation ball 10 is placed between the two fingers to be trained. Then, the two fingers are respectively placed inside the two inclined grooves 23, and then the operation ball 10 is pushed to move between the two fingers, thereby realizing the bifurcation training of the fingers;

[0028] Through the bifurcation training of the fingers, it indirectly lays a foundation for the subsequent flexibility training of the fingers and improves the practicability of the device.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
