Abstract:
1. A nail driver, comprising: a guiding plate including a punch channel; a securing slide rod including an extending portion, capable of slidably moving with respect to the guiding plate; a nail cartridge mounted to the guiding plate, having an inner space for including a nail pusher including a protrusion and at least one spring for pushing the nail pusher to press nails loaded in the nail cartridge toward the punch channel, and a cell connected to the inner space; a braking unit including one end formed as a retaining portion and the other end formed as a contact portion, which is pivotally installed in the cell so that the retaining portion will swing by exerting a force on the contact portion; and a resilient member installed in the cell, for pressing on the contact portion to swing the retaining portion to a releasing position without blocking a moving path of the extending portion so that the securing slide rod can freely slide to allow the nail drive to be actuated when there is at least one nail in the nail cartridge, such that when no more nail in the cartridge, the nail pusher pushed by the at least one spring causes the protrusion to press the contact portion against the bias of the resilient member to swing the retaining portion to a restraining position to block the moving path of the extending portion so that the securing slide rod can not freely slide to have the nail drive to be actuated.
