Abstract
A powder-actuated tool for driving fasteners, such as drive pins, into concrete, masonry, or steel workpieces comprises a tool body having a sleeve, a barrel extending forwardly from the tool body, a firing pin mounted operatively in the tool body and movable therein between a dormant position and a firing position, and a manually operable trigger for releasably latching the firing pin and for releasing the firing pin when the trigger is actuated with the firing pin in the dormant position. When moved to an actuated position with the firing pin in the dormant position and releasably latched a spring-loading element extending backwardly from the sleeve manually loads a spring compressively, so as to bias the firing pin toward the firing position.
