ABSTRACT:
The operation mode of a nailing machine can be automatically and reliably switched, for its selection, from the successive nailing mode and the one-shot nailing mode and vice versa by changing the order of operating a trigger lever and a contact arm. In the selected mode, the nailing work can be performed. By releasing both the trigger lever and the contact arm, the machine is returned to its initial mode. When the contact arm is moved to the top dead center after the trigger lever is operated, a portion of a slide die comes in contact with the underside of the trigger lever. When the trigger lever is operated after the contact arm is moved to the top dead center, the portion of the slide die comes in contact with the upper side of the trigger lever, thereby preventing a further movement of the contact arm to the bottom dead center.
