Patent ID: 7757588

Claim:
An adapter engagable in a hole of a driving end of a tool comprising: a body disposed in the hole and including an outer surface having a cavity formed therein, the cavity defining a side wall extending from a bottom wall; a cover capturing an elastic member against the bottom wall of the cavity to displaceably protrude outward from the outer surface of the body, the cover coaxially receiving a first end portion of the elastic member, the cover including a top surface and a depressible rim extending axially therefrom to be disposed peripherally about the first end portion of the elastic member, the depressible rim thereby extending axially along a portion of the elastic member to be captured against the side wall of the cavity, the elastic member being abutted by the cover and the bottom wall of the cavity, the elastic member including a second end portion having a section exposing outside the cover within the cavity, the exposed section of the elastic member being spaced by a gap from the side wall of the cavity; whereby the cover is linearly displaceable responsive to the elastic member; and wherein when the elastic member is depressed, the elastic member is compressed while remaining partially disposed within the depressible rim of the cover.
