Abstract: A device for impacting a fastener in one embodiment includes a trigger. A trigger disabling mechanism changeable between a first condition wherein operation of the trigger is not disabled and a second condition wherein operation of the trigger is disabled is also included. The device includes a nose piece configured to change the trigger disabling mechanism from the second condition to the first condition. The nose piece includes including a first nose portion removably coupled to a second nose portion. The first nose portion and the second nose portion define a channel therebetween through which a fastener is driven.

Abstract: A nail gun switch mechanism includes a gun body and a trigger. A safety slidable bar has a bottom part which extends outside of a hitting mouth at a bottom of the gun body. The trigger has a trigger lever being pivotably disposed therein. A top part of the safety slidable bar extends near to an end of the trigger and a swing arm is pivotably disposed on the top part of the safety slidable bar. The swing arm includes an arm part extending from a pivotal center of the swing arm and a push part extending from the arm part toward outside. The push part is configured to be switched to a first or a second swing position and thus driven by the safety slidable bar to touch the trigger lever so as to operate the nail gun in a sequential or a contact actuation mode.
