釘打機における釘送り機構。[Scope of Claim for Utility Model Registration] A striking cylinder, a striking piston that is slidably housed in the striking cylinder and has a striking driver integrally formed at one end thereof, and a striking driver that is disposed below the striking cylinder and has a striking driver integrally formed therein. an injection part formed in a substantially cylindrical shape in which the injection part can slide inside; a nail feeding member capable of reciprocating along a nail supply path connected to a nail supply port opened on a side surface of the injection part; and the nail feeding member. and a feed valve that drives the nail feeding piston by introducing and discharging compressed air into and discharging compressed air from the nail feeding piston/cylinder mechanism, the valve stem of the feed valve a feed lever provided with an end portion that can come into contact with the feed lever and that is manually operable near the grip portion; a first position that prevents the feed lever from coming into contact with the feed valve stem; a lock plate movable between a second position permitting abutment with the valve stem; and a lock plate actuated to engage said lock plate by compressed air supplied during operation of the nailer. while forcibly moving it to the second position,
and a lock stem that is maintained in this state, and by operating the feed lever, the engagement between the lock plate and the lock stem is released, the lock stem is returned to the position before operation, and the lock plate is returned to the first position. A nail feed mechanism in a nail gun characterized by being able to return to its original position.
