  • Patent number: 6357647
    Abstract: A nail-driving gun includes a safety rod disposed movably on a front end of a barrel, and a trigger member disposed movably on a handle. Upon actuation of the safety rod and the trigger member, the barrel shoots a nail therefrom. When the safety rod is pressed against a wall prior to actuation of the trigger member, the gun can be operated in a single shot mode, in which the safety rod is prevented from returning to its original position due to a hook member that is attached to the trigger member. When the safety rod is pressed against the wall after actuation of the trigger member, the gun can be operated in a continuous shooting mode. The safety rod and the trigger member can be actuated by one hand that holds the handle.
