Abstract
A pneumatic nail gun, relating to the field of power tools, including a body and nail feeding device, the body including cylinder and drive assemblies, the cylinder assembly including a first and second cylinder, striker, and interlocking structure, the first cylinder including a cylinder housing, first piston, and first chamber, the first piston having front and rear limit positions, the second cylinder including a barrel, second piston, and second chamber, the striker having initial and nail-striking positions which are synchronous to initial nail-striking positions of the second piston, an intake gap forms between the cylinder housing and first position at the front limit position so that external air flows into the first cylinder first chamber via the intake gap. Air intake into the first chamber is realized without forming holes on the sidewall of the cylinder housing, with improved intake efficiency of the first chamber and nail-driving performance.
