[0009] Further, the outer side surface of the friction pair keeps in contact with the inner side surface of the buffer cylinder, and the contact surfaces of the two are rough structures.

[0010] Furthermore, multiple groups of anti-slip groove structures are provided on the outer sides of the rotating teeth.

[0011] Furthermore, the contact ring is a hollow structure, and the size of the hollow structure in the middle is larger than the outer diameter of the hydraulic rod.

[0015] Compared with the known public technologies, the technical solution provided by this utility model has the following beneficial effects:

[0016] The utility model provides a buffering and noise reduction structure, through which the user can connect and fix the mounting bracket and the external structure.
