Abstract
A dual-mode ratchet wrench usable in either a reciprocating or a nonreciprocating mode is disclosed. The ratchet wrench includes a wrench body having a head portion and a handle portion, a rotatable drive unit, a ratchet mechanism, and a sleeve assembly that is axially translatable along the handle portion. In the reicprocating mode, the sleeve assembly is moved to a disengaged position wherein the wrench is operated by swinging the handle back and forth through an arcuate path. Due to the action of the ratchet mechanism, the drive unit is forced to rotate when the handle portion is swung in one direction, but not the other. In the nonreciprocating mode, the sleeve assembly is moved to an engaged position, wherein the inner end of the sleeve assembly engages the drive unit through a bevel gear system. The wrench is operated by rotating the sleeve assembly about an axial centerline through the handle of the wrench. Due to the interconnection of the sleeve assembly with the drive unit through the bevel gear system, the drive unit rotates when the sleeve assembly is rotated. A detent mechanism is included to retain the sleeve assembly in either the engaged or disengaged position.
