[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: Figure 1-3As shown, the utility model provides a friction type oblique compression spring clutch, with a speed change shaft 1 as the core component, and a friction mechanism 2 tightly arranged on one side thereof. The friction mechanism 2 is composed of a base plate 20 and a friction lining 21 and a flower groove 22 thereon. The flower shaft 25 of the speed change shaft 1 matches the flower groove 22 of the base plate 20 to ensure a firm connection between the two. At the same time, the limit button 23 on one side of the base plate 20 corresponds to the limit opening 24 on the buffer plate 26, and the buffer spring 28 further stabilizes this structure, thereby improving the overall stability. In addition, the clamping mechanism 3 is cleverly arranged between the friction mechanism 2 and the outer surface of the speed change shaft 1 to achieve effective compression of the friction mechanism 2.

[0018] The cooperation between the limit button 23 and the limit opening 24 of the buffer plate 26, as well as the annular distribution of the limit button 23, effectively improves the stability of the friction mechanism 2 on the speed change shaft 1, prevents shaking caused by friction, and extends the service life. The cooperation between the buffer groove 27 on the buffer plate 26 and the buffer spring 28 provides additional buffering effect for the friction mechanism 2, reduces the noise and wear caused by friction, and improves the durability of the clutch.

[0019] The detailed structure of the clamping mechanism 3 is revealed. The outer shell 30 serves as the main body, and a positioning groove 32 is provided in the positioning piece 31 fixed thereon for the sliding of the oblique clutch rod 33. The oblique clutch rod 33 cooperates with the moving groove 35 of the speed change shaft 1 through the moving ring 34 at the lower end, thereby realizing precise control of the clutch. At the same time, the sliding groove 37 of the outer shell 30 slides and fits with the outer surface of the speed change shaft 1, ensuring the stability of the clamping mechanism 3 during operation.

[0020] The positioning piece 31 is made of a metal material with memory, which ensures the stable sliding of the inclined clutch rod 33 in the positioning groove 32, and maintains good positioning accuracy even after long-term use. The sliding groove 37 of the housing 30 and the sliding fit of the speed change shaft 1, as well as the fit of the moving bayonet 36 and the moving groove 35, realize the precise clamping and stable control of the friction mechanism 2 by the clamping mechanism 3, and improve the operating accuracy and response speed of the clutch.

[0021] Working Principle: When the speed-shift shaft 1 rotates, the flower shaft 25 of the friction mechanism 2 closely cooperates with the flower groove 22 of the bottom plate 20, ensuring effective friction between the friction lining 21 and the transmission components. At the same time, the cooperation between the limit button 23 and the limit opening 24 of the buffer plate 26, as well as the buffering effect of the buffer spring 28, jointly maintain the stable position of the friction mechanism 2 on the speed-shift shaft 1, reducing wear and noise caused by friction.

[0022] The clamping mechanism 3 realizes the clamping and releasing of the friction mechanism 2 through the sliding of the oblique clutch rod 33 in the positioning groove 32, and the cooperation between the moving ring 34 and the moving groove 35 of the speed change shaft 1. When the clutch needs to be engaged, the oblique clutch rod 33 moves downward and pushes the friction mechanism 2 to make close contact with the transmission component through the moving ring 34. When the clutch needs to be disengaged, the oblique clutch rod 33 moves upward to release the clamping force on the friction mechanism 2, thereby realizing the separation of the clutch. At the same time, the sliding groove 37 of the housing 30 and the sliding fit of the speed change shaft 1 ensure the stability and accuracy of the clamping mechanism 3 during operation.

[0023] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
