For example, the patent name is a dust removal type automobile shock absorber (application number is 201420666355X). The shock absorber includes an oil storage cylinder, a working cylinder, a connecting rod, a guide, a piston valve assembly and a bottom valve assembly. The guide is arranged inside one end of the oil storage cylinder, one end of the working cylinder is fixed to one end of the guide, and the piston valve assembly The bottom valve assembly slides in the working cylinder, one end of the connecting rod is arranged at one end of the piston valve assembly, the bottom valve assembly is inserted into the oil storage cylinder at the end away from the guide and is fixed to one end of the working cylinder, and the hydraulic oil is located in the working cylinder. When the piston valve assembly slides in the working cylinder, the hydraulic oil flows in the piston valve assembly, thereby playing a buffering role. However, after the shock absorber has worked for a long time, the hydraulic oil in the shock absorber will age, so that the buffering effect of the shock absorber is reduced, so the hydraulic oil needs to be replaced, but the bottom valve assembly and the oil storage cylinder are interference fit, which is very inconvenient to disassemble, making the replacement efficiency of the hydraulic oil in the shock absorber low.

[0012] In summary, the present application includes at least one of the following beneficial technical effects:

[0013] 1. When the hydraulic oil in the shock absorber needs to be replaced, one end of the fixing buckle is toggled to allow the fixing buckle to rotate so that one end of the fixing buckle is detached from the side wall of the oil storage cylinder, and then the bottom cover can be removed from one end of the oil storage cylinder, and then the abutment block and the blocking ring are removed in turn, and then the hydraulic oil in the working cylinder can be tilted out, and then new hydraulic oil can be poured into the working cylinder, and then the blocking ring is inserted into the interior of one end of the working cylinder, and the abutment block is placed on one end of the blocking ring, and then the fixing buckle is rotated to allow one end of the fixing buckle to approach the middle of the bottom cover, and then one end of the bottom cover is inserted into the interior of one end of the oil storage cylinder until it is fully installed, and the fixing buckle is loosened so that one end of the fixing buckle is stuck into the interior of the side wall of the oil storage cylinder, so that the bottom cover is fixed in the oil storage cylinder. In summary, the shock absorber is very convenient to install and disassemble, which improves the efficiency of replacing the hydraulic oil in the shock absorber.

[0014] 2. When multiple fixing buckles need to be rotated, the rotating disk is driven to rotate, thereby driving multiple driving blocks to rotate. Since the distance between the driving blocks and the central axis of the rotating disk gradually increases from one side to the other side along the circumference of the rotating disk, multiple fixing buckles rotate simultaneously, thereby improving the convenience of driving multiple fixing buckles;

[0015] 3. Under the action of the compression spring, the bottom cover presses the compression spring, thereby pressing the abutment block, so that the blocking ring can better seal the working cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
