Abstract
A powered ratchet tool including a housing and a drive mechanism for driving an output member. The drive mechanism includes a yoke through which the output member extends. The ratchet tool further comprises a first selective pawl, a second selective pawl, and a non-selective pawl in the yoke that are biased toward an outer toothed surface of the output member and blocking member. The outer toothed surface includes first and second selectively-toothed sections. When the first selectively-toothed section and second selectively-toothed sections are rotationally aligned with the with the first selective pawl and the second selective pawl, the first and second selective pawls are incapable of transferring torque to the output member. The blocking member moves between an operating position, wherein the non-selective pawl is engaged with the outer toothed surface, and a home position, wherein the blocking member inhibits the non-selective pawl from engaging with the outer toothed surface.
