Abstract:
1. A nailing machine having a main body for containing a driving cylinder and a driving piston, a nose portion for guiding nails being installed at a lower portion of the main body, and a cartridge, the main body including a grip portion for guiding a compressed air toward the driving cylinder and a trigger lever mounted to a lower portion of the grip portion, the cartridge having a pressing plate and a pressing spring, one side surface of the pressing plate being covered by a cover, the pressing plate having function to push the nails toward the nose portion, characterized by comprising: a displaying unit having a display plate, a connecting plate and a trigger lever stopper, in which the display plate is formed in one body with the pressing plate and is perpendicular to the one side surface of the pressing plate, the displaying plate is projected toward the outside through a guiding hole formed through the cover in the longitudinal direction when the one side surface of the pressing plate being covered by the cover, the connecting plate is formed in one body with the display plate and extends toward the nose portion at a predetermined length along the one side surface of the pressing plate, the trigger lever stopper being mounted to an upper surface of the display plate, in which an insulating plate is attached to a distal end of the connecting plate, a conductive plate is attached to a part of an upper surface of the insulating plate; and an alarming unit including a first and a second ground plates formed at one side surface of the nose portion, a battery for supplying the first ground plate and the second ground plate with an electric source, and a recognition part, in which the first ground plate and the second ground pate are spaced apart from each other at a predetermined gap and they extend toward the connecting plate, a first ground protrusion and a second ground protrusion are respectively formed at the center portions of the first ground plate and the second ground plate, the conductive plate selectively contacting with the first ground plate and the second ground plate, the battery is disposed at the one side surface of the main body, the recognition part is disposed at a position adjacent to the battery and is electrically connected with the battery.
