Abstract
An air-path structure of a pneumatic nail gun includes a main chamber formed in a gun body, a piston driving chamber and a timekeeping chamber that continuously releases pressurized air to the outside. The gun body is equipped with a trigger valve and a bar valve, and a security chamber and an auxiliary chamber are formed in the trigger valve; the trigger valve controls the pressurized air in the piston driving chamber to be discharged to the outside; and the bar valve controls the pressurized air in the main chamber to go into the piston driving chamber, the timekeeping chamber and the auxiliary chamber. The security chamber is permanently connected to the main chamber for concentrating upon the pressurized air, and the bar valve controls the pressurized air in the main chamber to be discharged into the timekeeping chamber, so as to improve the safety of pneumatic nail gun when used.
