It is provided with piston 2 and piston rod 3；One end of the piston rod 3 is fixedly connected with the piston 2, and the other end is through axle sleeve 4, dirt
Closure set 5 and hole snap ring 53 simultaneously stretch out that cylinder body 1 is outer to be connected with cylinder cap 7；Wherein, ring is offered on the excircle of the axle sleeve 4
Shape neck, the sponge 41 being engaged with the inwall of cylinder body 1 is provided with the annular slot；The cylinder body 1 and the cylinder cap 7
Between be provided with spring 6；Described one end of spring 6 is connected in the first hierarchic structure formed on the cylinder body 1, and the other end abuts
In the second hierarchic structure formed on cylinder cap 7；Wherein, the piston 2 is in disc structure.
It is described to be covered with dust in order to improve the sealing in buffer between all parts on the basis of above-mentioned technical proposal
Sheath 5 is being provided with oil sealing 51 positioned at the side of axle sleeve 4, and described be covered with dust between sheath 5 and the cylinder body 1 is provided with the 2nd O
Type sealing ring 52.
On the basis of above-mentioned technical proposal, in order to improve the oil resistant of oil sealing, resistance to oxidation and resistance to elevated temperatures, the present invention
In, the raw material of above-mentioned oil sealing includes by weight：20 parts of hydrogenated nitrile-butadiene rubber, 17 parts of para-aramid fiber, 12 parts of boron phenolic, firmly
