Abstract
An adapter tool with a drill bit is provided that selectively connects to a driver to provide added versatility to the driver. The adapter tool includes a spring with an engagement end that extends through a body to selectively engage a recess in the driver. A user can actuate the spring to quickly engage and disengage the adapter from the driver. In practice, a user can use the adapter-driver combination to drill a pilot hole using the drill bit on the adapter, selectively remove the adapter from the driver, and then put a screw into the pilot hole using the driver.
Claims18
An adapter tool for selectively engaging and releasing a second tool, comprising:
- a body having a first end, an opposing second end, a longitudinal axis, and an inner surface that defines an interior volume configured to receive a second tool, wherein the body has a rounded outer surface proximate to said second end;
- a countersink cutter positioned at said second end of said body;
- a slot that extends from a first point at an outer surface of said body to a second point at said inner surface, wherein said slot forms an angle with said longitudinal axis;
- a spring positioned about said outer surface of said body, said spring having an engagement end configured to be positioned at least partially within said slot;
- and
- a retractable sleeve positioned about said outer surface proximate to said first end of said body and translatable along said longitudinal axis of said body between a first position and a second position, wherein, in said first position, said engagement end of said spring extends at least partially into said interior volume to engage said second tool, and wherein, in said second position, said retractable sleeve deflects said engagement end of said spring in said slot to move said engagement end away from said interior volume and to disengage said second tool.
A combined drill and driver system, comprising:
- an adapter tool having:
- a body having a longitudinal axis and an aperture forming an angle with respect to said longitudinal axis, wherein said angled aperture extends from an outer surface to an inner surface of said body, and said inner surface defines a partially enclosed volume, wherein said angled aperture is positioned proximate to a first end of said body, and a countersink cutter is positioned at an opposing second end of said body;
- a retractable sleeve disposed around said outer surface of said body and having an inner surface defining an inner cavity;
- a spring disposed around said outer surface of said body and at least partially positioned in said inner cavity, said spring having an engagement end at least partially positioned in said angled aperture of said body;
- a second tool removably interconnected and positioned in said partially enclosed volume, said second tool including a recess on a forward end,
- wherein, in a first state, said engagement end of said spring is wedged between a surface that defines said angled aperture and a surface of said second tool that defines said recess such that at least a portion of a cross-sectional area of said engagement end of said spring is positioned outside of said recess;
- and
- wherein, to transition from said first state to a second state, said retractable sleeve moves said engagement end of said spring against said surface that defines said recess such that said engagement end of said spring moves away from said longitudinal axis until said cross-sectional area of said engagement end of said spring is positioned outside of said recess in the second state.
