ABSTRACT:
A nail gun includes a moveable cylinder, an air collecting chamber and a main passage. An air passage includes a trigger valve; an air-in passage formed in the trigger valve connecting between an air collecting chamber and a main passage; an air-out passage formed in the trigger valve connecting between the main passage and external atmosphere; a stopper ring formed at an outside surface of the cylinder and slidably attached in the gun body; an air tank formed at a stopper ring; and a main chamber formed at a bottom portion of the stopper ring. The main chamber is capable of collecting the high pressure air via the air-in passage to actuate the cylinder to move up while the valve bar is pressed, and exhausting the high pressure air via the air-out passage to actuate the cylinder to move down for reposition while the valve bar is released.
