摘要：
A system for retracting the drive spindle of a power tool includes a drive shaft which has a spline portion and a threaded portion. During normal operation, the drive spindle is rotated by interconnection of a drive gear with the splined portion of the drive spindle. When it is desired to retract the drive spindle, a drive spindle feed gear is locked into position and the threaded engagement of the drive spindle feed gear and the drive spindle causes the drive spindle to retract.
