[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after shock absorption and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the driving smoothness of the car.

[0003] For example, a spring limiting structure disclosed in announcement number CN218935115U belongs to the field of spring technology. The spring limiting structure includes a limiting structure and a fixing structure, wherein the limiting structure includes a first fixing plate, a second fixing plate, a guide rod, a guide sleeve and a spring body, wherein the guide rod is connected to the first fixing plate, the guide sleeve is connected to the second fixing plate, the guide rod is slidably connected to the guide sleeve, the spring body is sleeved on the guide sleeve, and the fixing structure includes a clamping block and a fixing screw, wherein the first fixing plate and the second fixing plate are both slidably connected to one side with the clamping block, the clamping block is clamped to the spring body, and the clamping block is respectively connected to the first fixing plate and the second fixing plate through the fixing screw. In the present application, the spring limiting structure facilitates the installation and fixing of springs of different sizes, thereby improving the practicality of the device.

[0004] It can be seen from the above-mentioned public scheme that the spring currently arranged inside the shock absorber will be compressed and bent during use, and the spring will be damaged after long-term use, thereby reducing the use effect and service life of the spring. At the same time, the existing shock absorber spring is mostly arranged inside the shock absorber, but such a setting is not conducive to the maintenance, inspection and replacement of the spring. Utility Model Content

[0006] The cam is secured to the bottom of the cam and is designed to be easily removable, and the cam is secured on the bottom of the cam, and has a spring that allows the cam to slide and slide back into the bottom of the cam, the cam being easily removable and capable of sliding into the bottom of the cam.

[0007] Preferably, the anti-slip blocks are fixedly arranged on the left and right sides of the push block respectively, and the push rod slides through the interior of the blocking ring. The anti-slip groove is provided to be slidably connected with the anti-slip block, so as to limit the connection between the shell tube and the push rod to prevent the push rod from rotating inside the shell tube and affecting the operation of the shock absorber.

[0008] Preferably, the lower end of the spring is fixedly arranged on the upper end of the push plate, and the upper end of the spring is fixedly arranged on the outer surface of the blocking ring.

[0009] Preferably, the lower end of the bellows sleeve is fixedly arranged on the upper end of the push plate, and the spring is arranged inside the bellows sleeve.

[0010] Preferably, an upper ear plate is fixedly provided at the upper end of the upper connecting block, and a lower ear plate is fixedly provided at the lower end of the lower connecting block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model sleeves the spring on the push rod, and the push rod limits the spring, thereby preventing the spring from bending and deforming when stretched or compressed, preventing the spring from being damaged, and playing a protective role on the spring.

[0013] The utility model arranges the spring at the connection between the shell tube and the push plate, so that the spring can be easily removed and replaced. Moreover, the spring can be wrapped and protected by the arrangement of the corrugated sleeve, so that the spring can be prevented from being exposed to the outside and damaged.
