Abstract:
A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A rotary lifter is engageable with the driver blade and configured to receive torque from the drive unit for returning the driver blade from the BDC position toward the TDC position. The lifter has a body, a drive pin coupled to the body, and a roller positioned on the drive pin. The roller includes an engagement section configured to receive an end portion of a tooth of the driver blade. The lifter includes a means for aligning the engagement section with the end portion of the tooth on the driver blade to facilitate meshing between the end portion and the roller.
