ABSTRACT:
An improved pushbutton quick-release socket wrench includes an adaptor which comprises a hollow elongated member having a spring-loaded elongated member mounted axially within a central recess. A ball extends through the side wall of the member at one end of the member to engage a bearing recess in a socket which mounts to one end of the adaptor. A cam portion of the spring-loaded elongated member permits coupling of the ball to the mating socket when a plunger button on the wrench is depressed. Releasing the button drives the ball into contact with the socket recess to provide an integral structure for operating purposes. The adaptor is coupled to the driving stud of the wrench by driving a protruding ball into contact with a mating hole on the other end of the adaptor. The ratchet structure with a hollow stud extending therefrom with an axial plunger is mounted within a toothed recess in the wrench handle. Depressing the actuating button enables the ball to make contact with the adaptor recess to lock the adaptor thereto and also permits the socket to be connected to the other end by the cam action of the elongated member.
