Abstract: The present invention relates to a quick release mechanism for releasing a socket from a wrench. The wrench has a handle and a drive member mounted within the handle for rotation about an axis. The drive member has an aperture through its center and a drive portion having an outer surface and an inner surface, each surface for engagement with a socket, the aperture extending through the drive portion with the inner surface surrounding the aperture. The quick release mechanism is comprised of a cylindrical member mounted on the drive member for movement along the axis with respect to the drive member. The aperture through the cylinder member forms a portion of the aperture through the drive portion. The cylinder member has a finger engaging surface. At least one resilient spring member is provided, extending from an end of the cylindrical portion along the drive portion in a notch formed in the drive portion of the drive member. The spring member has a socket engagement surface extending out of the notch through one of the outer and inner surfaces for resiliently engaging one of the outer and inner surfaces to secure the socket on the drive portion. The drive portion of the drive member has a camming surface thereon so that movement of the cylindrical member in one direction along the axis with respect to the drive member cams the resilient spring member out of engagement with the socket to permit removal of the socket.
