As further program of the utility model: one end of described horizontal oil pipe is communicated with longitudinal oil pipe, and the other end of horizontal oil pipe is communicated with piston cylinder.
As further program of the utility model: described longitudinal oil pipe is provided with four, and is symmetricly set on the radial direction of second piston head.
As the utility model further scheme: described annular groove from the inside to the outside width diminishes gradually.
Compared with prior art, the beneficial effects of the utility model are: drift leading portion is not existed do not clean blind area by the first blower, the second blower orientation blowing, be conducive to cleaning material pipe, are released to initiatively release, work simultaneously due to lubricating oil
Plug chamber remains high pressure, and annular groove achieves full periphery release lubricating oil, can effectively live at material pipe and secondary like this
Add lubricating oil between chock plug, prevent lubricating oil from adding and unevenly cause piston outer wall face or material inside pipe wall surface wear problem, suitably can shorten the blowing cleaning time, be conducive to maintenance and the control of temperature equally.
