Abstract
A power actuated tool for driving a fastener into a work surface includes a firing pin for firing an explosive charge to drive the fastener. The firing pin is held in a cocked position against a spring bias by a rotary sear which is displaced rearwardly during cocking by pressing a barrel against the work surface. In the cocked condition, the sear is aligned with a trigger mechanism which can be actuated to pivot the sear and thereby cause release of the firing pin which is then driven by the spring bias to fire the charge.
