Nail placement device

摘要

A fastener driving device including a positioning mechanism for positioning a nail into an opening in a workpiece. The positioning mechanism includes an opening locating structure movably connected to the movable assembly of the contact trip assembly and adapted to extend into the opening so as to align the nosepiece with respect to the opening. The opening locating structure is movable relative the movable assembly of the contact trip assembly between an extended position and a retracted position and biased toward the extended position by a first biasing spring to facilitate locating of the opening, and movable to the retracted position when the opening locating structure is pressed against a workpiece. The positioning mechanism further includes a guiding structure movably connected to the nosepiece structure, the guiding structure being biased by a spring to extend forwardly to guide the fastener in a driving track inside the nosepiece.
