Patent ID: 7121443

Claim:
An electric nailing apparatus comprising: a triggering member; a rotatable rod member disposed between said triggering member and a first switch device and comprising first and second sustaining structures at different locations thereof; a transmission rod having thereon a first protrusion structure and disposed in a receptacle member; a motor member pivotally coupled to the lower portion of a gear member and electrically connected to said first switch device so as to drive said gear member; and a ram block disposed above said gear member, sustained against a fixture element via a resilience element, and in response to a rotation of said gear member, gliding to compress said resilience element and then touch said first protrusion structure, wherein in response to an external force, said triggering member moves from a first location to a second location to have said first sustaining structure of said rotatable rod member sustained against a triggering point of said first switch device so as to start running of said motor member, and after said ram block is in contact with said first protrusion structure, said second sustaining structure is simultaneously stirred by said transmission rod to have said first sustaining structure detached from said triggering point of said first switch device so as to stop running of said motor member and provide a nailing energy to said ram block in response to a recovery force of said resilience element.
