[0002] With the increase of urban traffic congestion and people's demand for convenient travel, electric scooters, as a light and flexible means of transportation, are favored by more and more consumers. At present, most electric scooters on the market use simple shock-absorbing structures, such as rubber shock-absorbing pads or simple spring shock-absorbing structures. Although these shock-absorbing structures can reduce vibration to a certain extent, the effect is limited, and the adjustability is not strong, which cannot meet the needs of different riders.

[0003] In order to solve the above problems, a front shock-absorbing mechanism for an electric scooter is proposed in the publication (announcement) number CN205737926U. A clamping block is arranged on the shock-absorbing spring. The clamping block is connected to a lead screw. The downward pressure and upward movement of the clamping block are adjusted by the rotation of the lead screw, thereby adjusting the elastic strength of the spring. However, when the shock-absorbing spring reaches the end of its service life, in order to save costs, only the shock-absorbing spring is often replaced. The above device is relatively complicated and cumbersome to operate when replacing the shock-absorbing spring.

[0004] The above contents are only used to assist in understanding the technical solution of the present application, and do not constitute an admission that the above contents are the closest prior art to the present application. Summary of the invention
