Depth adjustment assembly for power tool

A hand-held tool for use with a tool attachment, the hand-held tool comprising:

• a tool housing,
• a depth adjustment assembly releasably supported on the tool housing, the depth adjustment assembly including a locator extending forwardly from the tool housing and having a central bore adapted to house the tool attachment, and means for adjustably attaching the locator to the tool housing such that the position of the locator can be adjusted forwardly and rearwardly with respect to the tool housing, the means for adjustably attaching the locator to the tool housing including means for supporting the locator for rotation with respect to the tool housing to provide for axial adjustment of the position of the locator with respect to the tool housing, and the means for adjustably attaching the locator to the tool housing including means for supporting the locator such that the locator can be removed from the tool housing without varying the relative axial position of the locator with respect to the tool housing when the locator is repositioned on the tool housing.

A hand-held tool as set forth in claim 13 wherein the sleeve is supported on the tool housing such that it is non-rotatable with respect to the tool housing.

A hand-held tool for use with a tool attachment to drive fasteners relative to a workpiece, the hand-held tool comprising:

• a tool housing,
• a depth adjustment assembly including an annular sleeve having a threaded portion and means for providing a releasable snap-fit engagement between the sleeve and the tool housing, the means for providing a releasable snap-fit engagement including first detent means for preventing axial movement of the sleeve relative to the tool housing when the sleeve and the tool housing are in snap-fit engagement and second detent means for preventing relative rotation between the sleeve and the tool housing when the sleeve and the housing are in snap-fit engagement, a locator extending forwardly from the tool housing and defining a central bore adapted to house the tool attachment, the locator including a threaded portion threadably housed by the threaded portion of the sleeve such that the relative housing can be adjusted forwardly and rearwardly by rotating the locator with respect to the the tool housing, and indexing means between the locator and the sleeve, the indexing means includes a plurality of resilient fingers projecting from the locator and a plurality of complementary recesses provided in the sleeve to releasably house at least portions of the resilient fingers.

A hand-held tool for driving a fastener into a workpiece, said tool comprising:

• a housing,
• a drive meachanism housed in said housing and including a tool attachment extending from said housing and being adapted to drive the fastener relative to the workpiece, and
• means supported on said housing for controlling the axial depth to which the fastener is driven relative to the workpiece, said means for controlling the depth to which the fastener is driven including an annular sleeve, and a locator extending forwardly from the tool housing and defining a central bore adapted to house the tool attachment, said locator including an inner surface having a cylindrical inner surface portion, said cylindrical inner surface portion having an axial length, and said cylindrical inner surface portion being engageable with said tool attachment along its entire axial length, and axial extending grooves in said cylindrical inner surface portion and extending the axial length thereof, and one of said sleeve and said locator being moveable to adjustment the position of the locator forwardly and rearwardly with respect to said housing.
