Abstract
Abstract An adapter sleeve to be carried by the tool head end of a handle is provided including a first end for receiving the head end of a handle therein and a second end for receiving the free end of a tool head supported shank. The second end of the sleeve includes a generally radial bore for registry with a radial bore formed in the free end of the tool head shank and an elongated spring arm having base and free ends is provided and extends longitudinally of the sleeve with the free end thereof closely adjacent the radial bore formed in the sleeve and the base end of the arm attached to the sleeve at a point spaced toward the first sleeve end from the radial bore of the sleeve. The spring arm has a slide mounted thereon and the sleeve includes a cam surface relative to which the slide is shifted during movement of the slide along the arm. The slide and cam surface coact to outwardly deflect the free end of the spring arm away from the sleeve as a result of movement of the slide along the arm in one direction and the spring arm free end includes a laterally inwardly projecting pin portion which is received through the sleeve radial bore and in the radial bore formed in the free end of the shank. When the slide is shifted relative to the arm, along the cam surface to effect outward displacement of the free end of the arm, the pin portion is outwardly retracted relative to the radial bore in the tool head shank thereby enabling withdrawal of the shank from the sleeve.
