Specifically, when the shock absorber is in a compression state, the oil enters the bottom of the high-speed regulating valve from the oil inlet 11. Due to the obstruction of the lower valve plate 33 at the bottom of the one-way piston 31, the oil cannot pass through the recovery hole 36. Therefore, it passes through the compression hole 35, pushes open the upper valve plate 32 and the valve cover 7 on the one-way piston, passes through the oil hole 21, and flows out from the oil outlet 12; by rotating the adjustment wheel 5, the adjustment core 4 can be moved up and down, changing the compression amount of the butterfly spring 6, thereby changing the pressing force of the valve cover 7 on the upper valve plate 32, and then affecting the opening of the upper valve plate 32, playing a role in adjusting the compression damping, thereby achieving precise adjustment of the oil flow and the damping force of the shock absorber, so that the user can adjust the shock absorber performance according to different road conditions and further improve the driving experience. When the shock absorber is in a recovery state, the oil enters from the oil outlet 12, flows to the one-way valve through the oil hole 21, and can easily push open the lower valve plate 33 and the spring plate 34 through the recovery hole 36, and flow to the oil inlet.

[0022] In this embodiment, a cylindrical pin 8 is horizontally arranged in the middle of the compression positioning seat 2, and an arc-shaped guide groove 41 is opened on the surface of the adjustment core 4. One end of the cylindrical pin 8 passes through the spiral groove and is embedded in the arc-shaped guide groove 41, which can guide and axially position the adjustment core 4.

[0023] In this embodiment, a dust cover 9 is provided on the top of the adjusting core 4 and fixed by a hexagon socket screw. The dust cover 9 plays a role of dust prevention.

[0024] In this embodiment, the upper valve plate 32 is composed of a plurality of valve plates of different sizes and thicknesses.

[0025] In this embodiment, a gasket 10 is arranged on the top of the butterfly spring 6. After the gasket 10 is stressed, it applies force to the butterfly spring 6, so that the butterfly spring 6 is stressed more evenly, which is beneficial to adjust the compression damping.

[0026] In this embodiment, sealing rings are arranged between the seat and the compression positioning seat, between the compression positioning seat and the adjusting core, and between the adjusting core and the one-way piston valve system to ensure the sealing between the components and avoid oil leakage.
