Abstract
A nail-driving device has a housing, a trigger unit, a safety unit, a connecting unit and a magazine. The safety unit has first and second safety members in the housing. The connecting unit is connected pivotally to the second safety member, and has a retaining portion disposed movably between the first and second safety members. The magazine has a pusher for pushing nails therein. When the retaining portion is in a retaining position, a force is applicable to the first safety member to move the second safety member to pivot a trigger arm for a nail-driving operation when the trigger unit is actuated. When the nails thereof are exhausted, the pusher moves to a retention releasing position to pivot the connecting unit and remove the retaining portion from the retaining position to allow for relative movement of the first and second safety members to prevent the nail-driving operation.
