Abstract

The embodiment of the present disclosure relates to the technical field of electric tools, and provides a nail gun, which comprises a casing, a cylinder assembly, a striker, and a piston. The cylinder assembly is accommodated into the casing and comprises an inner cylinder and an outer cylinder. The striker is movably connected to the cylinder assembly, and the cylinder assembly provides power for the striker to shoot nails. The rear end of the striker is provided with the piston, and the piston moves forward and backward along the inner wall of the inner cylinder. The front end of the inner cylinder is provided with an exhaust guide groove and an exhaust hole. The first end of the exhaust guide groove is communicated with the inner cavity of the inner cylinder, the second end of the exhaust guide groove and the exhaust hole are communicated, and the inner cylinder is communicated with external gas through the exhaust guide groove and the exhaust hole. The piston drives the striker to move forward to shoot nails, and the gas at the front end of the inner cylinder is discharged from the exhaust guide groove and the exhaust hole. At least, the problem that the gas in the cylinder at the front end of the piston is not easily discharged in the prior art is solved.
