Abstract
A nailer includes a gun body, a safety lever, a push device, and a contact trigger device. The push device includes an urging member, and a torsion spring, and the contact trigger device includes a mounting member, an O-ring, an elongated contact member, and an elastic member. The torsion spring has an elastic force smaller than that of the elastic member. Thus, the nailer is operated only when the first end of the safety lever is initially pressed on a workpiece and the trigger is then pressed, thereby providing a safety function to the user.
