  • Patent number: 7121443
    Abstract: An electric nailing apparatus includes a triggering member, a rotatable rod member including first and second sustaining structures, a transmission rod having a first protrusion structure, a motor member and a ram block sustained against a fixture element via a resilience element. In response to a rotation of a gear member, the ram block glides to compress the resilience element and then touch the first protrusion structure. In response to an external force, the triggering member moves to have the first sustaining structure touch a first switch device to start the motor member. After the ram block touches the first protrusion structure, the second sustaining structure is simultaneously stirred by the transmission rod to have the first sustaining structure detached from the first switch device, thereby stopping the motor member and providing a nailing energy to the ram block in response to a recovery force of the resilience element.
