Abstract: Disclosed is a pneumatic nailing gun. According to the pneumatic nailing gun, an end cover is provided with a locking seat, a locking block is slidably connected in a sliding groove, a moving end of the locking block abuts against an elastic member located at an end portion of the sliding groove, a locking end of the locking block is capable of abutting against a locking member and limiting the movement of the locking member, the locking block is further provided with an open groove, a first piston is provided with an ejector rod, the locking seat is provided with a first bayonet allowing the ejector rod to enter, the ejector rod includes a jacking end and an abutting end arranged on a side edge of the jacking end, the locking seat is further provided with a second bayonet.

Abstract: The new invention is a portable tool, specifically directed electric motor driven nail gun. It has a nail push system, also a motor. The motor uses a flywheel as a speed reduction mechanism, the main characteristic is that the drive unit of the driving mechanism is connected to a pitman by a pin axis on one end, and the other end is connected to the pin axis which does the arc movement. The end of the drive unit props up the long slot by a spring and enclosed by the long slot in a sliding movement. The rectilinear reciprocating drive unit is governed by a clutching mechanism mounted on the speed reduction mechanism. The new invention can provide a powerful impacting force. The clutch bar of the driving mechanism has an outer bulge and inner bulge, it controls the tension spring which makes the drive unit impact nails and recover after impacting nails, without any memory of the rotating state.

Abstract: The new invention is a portable electric power tool, specifically directed to driving a fastener into a substrate as an electric motor driven nail gun. It has a bracket, switch, control unit, magazine and nail push system, also a motor which derives its power from a power supply or rechargeable batteries. The motor drive uses a flywheel as a speed reduction mechanism, a main characteristic is that the drive unit of the driving mechanism is connected to a pitman by a pin axis on one end, and connected to the pin axis on the other link which does the arc movement. The other end of the drive unit is connected with a spring and long board to the long slot in a sliding movement. The clutching mechanism of the speed reduction mechanism controls the anvil to do linear movement driven by the rotational motion of the flywheel. The new invention can be slim, simply and easily assembled, and provide a powerful impacting force.
