Abstract
A tip and adapter assembly includes a spring loaded retainer that includes a lug receiving portion defining a first maximum outside dimension, the lug receiving portion also defining a lug receiving slot that extends partially through the lug receiving portion, forming a first sidewall, a second sidewall, and a catch surface connecting the first sidewall to the second sidewall. A drive portion defines a second maximum outside dimension, and a first flat is disposed on the outside of the lug receiving portion proximate to the first sidewall or the second sidewall.

A tip and adapter assembly comprising:
- a tip that includes a body that defines a longitudinal axis, a vertical axis that is perpendicular to the longitudinal axis, and a lateral axis that is perpendicular to the vertical axis and the longitudinal axis, the body including:
- a forward working portion disposed along the longitudinal axis including a closed end;
- and
- a rear attachment portion disposed along the longitudinal axis including an open end;
- wherein the rear attachment portion defines
- an exterior surface;
- an adapter nose receiving pocket extending longitudinally from the open end;
- a retaining mechanism receiving aperture in communication with the adapter nose receiving pocket and the exterior surface;
- an adapter nose lug receiving groove extending longitudinally from the open end to the retaining mechanism receiving aperture;
- and
- at least one spring receiving slot that is in communication with the retaining mechanism receiving aperture and the adapter nose receiving pocket;
- and
- an adapter that includes a body comprising a nose portion that is configured to fit within the adapter nose receiving pocket of the tip.
