Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption, and specifically relates to a self-centering L-shaped bracket clamping system for shock absorber installation. Background Art

[0002] When installing a shock absorber, in order to ensure the stability of the center of gravity of the shock absorber, it is often necessary to perform centering detection on the bracket at the end of the shock absorber. Only when the center of the bracket is consistent with the center of the shock absorber can the long-term stable operation of the shock absorber be ensured.
