[0002] In the automobile modification market, a car user wishes to manually adjust the attitude of a vehicle to adapt to different use requirements. For example, when racing on a flat road, the car user manually adjusts the attitude of the vehicle to be low, so that the automobile looks better. When needing to go on an uneven road, the user adjusts the attitude of the vehicle to be high to adapt to the relevant road conditions. Since the front shock absorber is generally installed above the wheel, and the rear shock absorber is installed on the side of the wheel, when the attitude of the vehicle is adjusted, the vehicle is generally first lifted, then the wheel is disassembled, the adjustment is made by using a tool, and the vehicle is lowered after the tire is installed and the vehicle attitude is measured to confirm whether it is correct. This way of adjusting the high-low attitude of the automobile has the problem of difficult operation. SUMMARY

By moving the posture adjusting assembly 4 in the mounting frame 1 along the axial direction of the damper 3, the damping spring 2 can drive the vehicle body to move up and down relative to the wheels, thereby adjusting the height of the vehicle body. The conventional damper is mostly mounted on the bottom of the vehicle body, which is inconvenient for adjustment. In the present application, the posture adjusting assembly 4 is arranged, so that the structure for adjusting the height of the vehicle body extends away from the bottom of the vehicle body by a distance, thereby facilitating the adjustment of the height of the vehicle body by the operator. For example, when the present application is applied to the front wheels, the mounting frame 1 is mounted on the vehicle body near the front wheels, the posture adjusting assembly 4 is mounted on the mounting frame 1, and the upper part of the posture adjusting assembly 4 is exposed through the mounting frame 1 by a certain structure, so that the top of the posture adjusting assembly 4 is located near the engine. Therefore, when the operator adjusts the height of the vehicle body near the front wheels, the operator only needs to open the front hood to find the posture adjusting assembly 4, and then adjusts the corresponding position of the vehicle body by controlling the position of the posture adjusting assembly 4 in the through hole 11.

[0027] In an embodiment, the first hollow structure 41 is provided with a first internal thread, and the stroke adjustment assembly 5 is provided with a first external thread matched with the first internal thread. In this embodiment, the stroke adjustment assembly 5 is threadedly connected with the posture adjustment assembly 4, and the up-down movement of the stroke adjustment assembly 5 in the posture adjustment assembly 4 is achieved by screwing the stroke adjustment assembly 5.
