[0012] In a preferred embodiment, a notch is provided on one side of the surface of the connection between the metal outer sleeve and the rubber inner sleeve.

[0013] By adopting the above technical solution, the provided notches facilitate the connection between the metal outer sleeve and the rubber inner sleeve.

[0014] In a preferred embodiment, a vulcanized base is disposed at the lower part of the shock-absorbing bushing body, and a plurality of rubber holes are formed on the surface of the vulcanized base.

[0015] By adopting the above technical solution, the rubber pull-off force can be effectively increased by opening a plurality of rubber holes on the surface of the vulcanized base arranged inside the shock-absorbing bushing body.

[0016] In a preferred embodiment, a plurality of grooves are arranged on the surface of the connection structure inside the shock-absorbing bushing body.

[0017] By adopting the above technical solution, the multiple grooves arranged inside the structure facilitate the installation and connection of other structures.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] In the present application, by arranging an annular block, a fixing ring and its internal connecting structure on the outer surface of the shock-absorbing bushing body, the shock-absorbing effect of the device can be greatly improved when the shock-absorbing bushing body is subjected to a large vibration impact.
