Specific implementation mode
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited
In following embodiments.
As depicted in figs. 1 and 2, the present embodiment includes cylinder body 1, piston 2, the first O-ring 5, the second O-ring 7, sealing rubber ring
4 and cushion rubber mounting base 3, cylinder body 1, piston 2, the first O-ring 5 and the second O-ring 7 form air cylinder structure, and sealing rubber ring 4 is installed on
In cushion rubber mounting base 3, cushion rubber mounting base 3 is connected through a screw thread fixation with cylinder body 1, and 4 internal diameter of sealing rubber ring is slightly larger than circle to be held
The outer diameter of shape pipe fitting.
Test mouth 8, driving mouth 9 and venthole 10 are provided on cylinder body 1, by driving mouth 9 to be filled with into the cavity of cylinder
Compressed gas (being commonly compressed air) makes piston 2 be pressurized and generates motive force, forces sealing rubber ring 4 in 3 He of cushion rubber mounting base
