ABSTRACT:
A pneumatic nail gun includes a gun body, a connecting mechanism, an acting valve, a trigger, a safety valve, and a trigger valve. The gun body includes a safety compressed air inlet and a firing compressed air inlet. The connecting mechanism is slidably disposed on the gun body. The acting valve is connected to the connecting mechanism. The trigger is connected to the gun body. The safety valve is connected to the acting valve for allowing a safety compressed air coming from the compressed air source to drive the acting valve to move the connecting mechanism forwards when the trigger is pulled. The trigger valve releases a firing compressed air coming from the compressed air source to project at least one nail only when the trigger is pulled, a workpiece blocks the connecting mechanism, and the trigger opens the trigger valve.
