Help
      1, bottom reducer to connect with the valve, stent surface and the cylinder connected to valve shaft and worm gear through the inner hole with the valve shaft square hole with the Quartet and the cylinder; (work process: pneumatic valve when the cylinder drive shaft, worm gear with the switch . manually when the worm and worm gear to drive valve shaft rotation, the cylinder piston moving in tandem.
      Second, turn the handle (outer turn 180 degrees) in the close the worm, it will appear the phenomenon of top gear, will have to turn round a point of view can be combined hands-on;
      Third, reducer stent covered with three kinds of, the user can choose according to need, configure different types of cylinder;
      4, pneumatic and manual can not simultaneously drive.
