Patent attributes
A nail-driving device includes a body having a nail ejection portion, a nail-striking member, an activation switch, a trigger mechanism, a force-transmitting member, and a safety mechanism. The force-transmitting member is connected pivotally to the safety mechanism. When the safety mechanism is limited in a first position, and when the trigger mechanism is actuated, the force-transmitting member activates the activation switch to thereby move the nail-striking member relative to the body. When movement of the safety mechanism relative to the body is allowed, and when the trigger mechanism is actuated, the force-transmitting member moves the safety mechanism from the first position to a second position such that a contact portion of the activation switch serves as a fulcrum.
