The riveting gun is characterized in that the rivet core clamped in a gun head during riveting can be easily taken out. The riveting gun comprises handles, support rods and the gun head, a pull-out sleeve connected with clamping jaw seats is arranged on the rear portion of the gun head, a through hole is formed in the middle of the rear end of the pull-out sleeve, the rear end of the pull-out sleeve is connected with a piston sleeve, a piston rod is arranged inside the piston sleeve, and the front end of the piston rod penetrates through the through hole of the pull-out sleeve to enter a space between the two clamping jaw seats. One end, connected with the pull-out sleeve, of the piston sleeve is open, and the other end of the piston sleeve is closed. One end of the piston rod is provided with a cylindrical piston cap, the other end of the piston rod is provided with a piston pin which is thinner than the piston rod cap, the piston rod cap faces towards the closed side of the piston sleeve, and the piston rod pin extends into the middle position between the two clamping jaw seats in the gun head. During riveting operation, if the rivet core is adhered to multi-tooth clamping jaws and clamped in the gun head, an operator can grip the handles to shake the gun head to enable the piston rod pin to slide into the gun head, so that the rivet core adhered to the multi-tooth clamping jaws can be expelled out.
