Claims

[Scope of Claim for Utility Model Registration] This driver is integrally connected to a striking driver that reciprocates through an injection hole in a nose protruding from the nailer body and drives out nails supplied into the injection hole from the tip of the nose. a percussion piston, a percussion cylinder in which the percussion piston is slidably and tightly fitted, a main air chamber connected to an air pressure source, and a space between the piston upper chamber of the percussion cylinder and the main air chamber or for exhaust. A head valve for switching operation between the injection hole and the injection hole, a trigger valve for sending an activation signal to the head valve, and a continuous supply of interconnected nails into the injection hole through an opening formed in the side surface of the nose. A pneumatic nailing machine having a nail supplying means, comprising: an extrusion member configured to be retractable in the radial direction of the nose; and a nail being connected to the extrusion member by moving the extrusion member when the extrusion member is projected into the nose. a cylinder mechanism that disengages from the connecting nail and projects a predetermined length from the tip of the nose; and when loading a connected nail into the nail supply means, upon completion of loading, the leading nail is disengaged from the connected state and is supported so as to protrude from the tip of the nose. A pneumatic nailing machine characterized by comprising means for controlling the operation of the extrusion member and the cylinder mechanism.
