Impact tool driver

摘要

A portable impact tool driver is removably attachable to a drive spindle or shaft of a conventional power tool. The impact tool driver has a body member with a drive shaft configured with the body member so as to be rotationally driven thereby. A hammer member is rotationally coupled to the drive shaft and is rotationally driven by the drive shaft. The hammer member is also axially movable along the drive shaft. The hammer has a first impact face configured thereon with at least two impact drivers defined on the impact face. A coupling drive mechanism is disposed between the drive shaft and the hammer member and imparts a rotational and longitudinal movement to the hammer member. An anvil member has a second impact face opposite the first impact face with an impact receiver configured thereon for periodic impacting engagement with the impacted drivers. The hammer member is rotationally driven by the drive shaft while simultaneously being moved axially back and forth relative to the drive shaft so that the impact drivers move into and out of rotational impacting engagement with the impact receivers defined on the anvil member.
