APPARATUS FOR ADJUSTING THE RELATIVE POSITIONS OF TWO COMPONENTS OF A POWER TOOL

摘要

An apparatus for adjusting the relative positions of a first component and a second component of a power tool includes a drive rod which interconnects the fi rst and second component. The drive rod has a plurality of external threads in meshi ng engagement with a plurality of internal threads located on one of the first and second components. An internally threaded element preferably in the form of a backlash nut is also in meshing engagement with the plurality of internal threads. A biasing member is interdisposed between the internally threaded element and one of the f irst and second component. In a preferred form, the apparatus is incorporated into a power tool for woodworking or metal forming and is operative for eliminating pla y in the threaded interconnection of the components which is most evidence upon rever sal of movement of the drive rod.
