Socket wrench including quick-release adaptor

A socket wrench comprising:

• a wrench portion including an elongated handle and a head portion at one end with an aperture therethrough,
• an insert mounted within the head aperture and driving means coupling the insert to the head portion, said insert being rotatably driven by the action of the wrench portion upon actuation thereof through the driving means and said insert having an aperture extending axially therethrough, and including an elongated pushbutton slidably mounted within the axial aperture and normally protruding therefrom at one end and a stud portion at the other end from which the pushbutton moves outwardly when depressed at its other end,
• a socket having a body portion, upper and lower axial apertures, a first inner portion in the upper aperture comprising interior walls having at least one locking recess therein and a second outer portion in the lower aperture of enlarged diameter comprising interior walls having gripping means spaced thereabout, and,
• a one piece hollow adaptor having means at one end to removably engage the insert stud, said means being coupled to the pushbutton for actuation thereby and coupling means at one end to engage a locking recess in the upper socket aperture, a slidable shaft mounted axially within the adaptor and in engagement therewith and engageable by the pushbutton at one end to be moved downwardly within the adaptor to actuate the coupling means cooperating with the socket and whereby depressing the pushbutton a first distance selectively actuates the coupling means to disengage the shaft from the locking recess in the socket wall releasing the socket from the adaptor and further depression of the pushbutton disengages the adaptor engaging means from the stud freeing the adaptor from the insert.
