[0002] Shock absorber is used to suppress the shock of spring shock-absorbing rebound and the impact from the road. It is widely used in automobiles to accelerate the damping of vehicle frame and body vibration, so as to improve the ride comfort of the automobile.

[0003] When passing through uneven road, although shock-absorbing spring can filter the vibration of road, spring itself will still have reciprocating motion, and shock absorber is used to suppress this spring jumping. If shock absorber is too soft, vehicle body will jump up and down, and if shock absorber is too hard, it will bring too much resistance, which will hinder the normal work of spring. In the process of modifying the suspension system, hard shock absorber should be matched with hard spring, and the hardness of spring is closely related to vehicle weight, so heavier vehicles generally use harder shock absorber to suppress the shock of spring shock-absorbing rebound and the impact from the road.

[0004] Shock absorber is of fixed length, that is, the installation length of rear shock absorber is fixed. Its length cannot be adjusted according to actual use, which leads to the need of different shock absorbers for different models of vehicles during use, and the length cannot be used universally, resulting in increased cost.

[0037] Extension rod 5 is arranged in recess 4, and top end penetrates annular plate 3;

[0038] The top end of extension rod 5 is fixedly installed with second connecting piece, can be connected with external vehicle, while extension rod 5 slides upwards, can extend the distance between first connecting piece and second connecting piece, it is convenient to connect adaptation with different equipment outside;

[0039] Locking mechanism is arranged in the upper end surface of annular plate 3, for locking the position of extension rod 5.

[0040] Specifically, locking mechanism includes;

[0041] Fixed block 6 is fixedly installed on the upper end surface of annular plate 3;

[0042] Plug-in slot 7 is formed in the end surface of fixed block 6 close to extension rod 5;

[0043] Through port 8 is formed in extension rod 5.

[0044] The plurality of through holes 8 are formed in the extension rod 5;

[0045] The connecting block 9 is fixedly installed on the upper end surface of the annular plate 3;

[0046] The sliding hole 10 is formed in the connecting block 9;

[0047] The locking pin 11 is arranged in the sliding hole 10 and penetrates the through hole 8 and is inserted into the insertion slot 7;

[0048] The locking pin 11 penetrates the through hole 8 and is inserted into the insertion slot 7, so that the position of the extension rod 5 can be locked and fixed relative to the sliding rod 2.

[0049] Specifically, the locking pin 11 is formed with a through hole 12, the lower wall surface of the sliding hole 10 is formed with a threaded groove 13, the connecting block 9 is provided with a bolt 14, one end of the bolt 14 penetrates the through hole 12 and is threadedly connected with the threaded groove 13;

[0050] Under the action of the bolt 14, the through hole 12 and the threaded groove 13, the locking pin 11 can be fixed in the sliding hole 10 and kept fixed.

[0051] Specifically, the shell 1 is filled with oil, the shell 1 is provided with a sliding plate 15, the upper end surface of the sliding plate 15 is fixedly connected with the lower end of the sliding rod 2, the sliding plate 15 is formed with a through hole 16, and the outer surface of the sliding rod 2 is wound with a compression spring 17, both ends of the compression spring 17 are fixedly connected with the upper end surface of the shell 1 and the lower end surface of the annular plate 3;

[0052] When the sliding rod 2 drives the sliding plate 15 to slide in the shell 1, the oil in the shell 1 can flow through the through hole 16, which can play a damping role, and the compression spring 17 can exert a force on the annular plate 3, which can play a damping role.
