Patent ID: 6912932

Claim:
A depth adjusting system for a tool comprising: a tool housing; a base releasably attached to the tool housing; an on/off collar removably attachable to the base so that the on/off collar is not rotatable relative to the base when it is attached thereto; an adjusting collar mounted to the on/off collar and being rotatably but not axially moveable relative to the on/off collar; a depth locator mounted to the on/off collar and being rotatably and axially moveable relative to the on/off collar, the axial movement of the depth locator occuring in proportion to and in response to the relative rotation between the depth locator and the on/off collar, the depth locator establising a depth setting of the depth adjusting system; and complementary threads formed on an exterior surface of the depth locator and on an interior surface of the on/off collar for mounting the depth locator to the on/off collar, wherein the depth setting of the depth adjusting system can be adjusted by rotating the adjusting collar which in turn drives the depth locator to rotate in unison, such rotation causing axial movement of the depth locator.
