Abstract: A no-idle-striking structure for nailing machines including a strike assembly, a bumper bar, a magazine, and a follow plate. The bumper bar is provided with a hook which may extend into a magazine support. The follow plate has a stop portion. When there are nails in the magazine, the bumper bar is in normal state so that pulling of the trigger will cause a nail to be driven into a workpiece. But when the nails are used up, the follow plate will elevate to the position of the magazine support so that its stop portion will restrain the hook of the bumper bar from displacing rearwardly. As a result, pulling of the trigger will not effect any striking.
