[0038] Working principle: When replacing the damping shock absorber body 1, you only need to pull the pull rod 5, and the pull rod 5 will drive the offset rod 7 to move through the pull plate 6, and then drive the block 9 to move through the slide plate 8 so that the block 9 and the slot opened in the connecting block 3 cannot be engaged, and then pull out the connecting block 3 to complete the disassembly. When installing, you only need to pull the pull rod 5 to drive the block 9 to move, and it will squeeze the spring 11, and then insert the connecting block 3 into the supporting block 4 to release the pull rod 5.
