ABSTRACT:
A device for positive ejection of cylindrical socket wrenches from a retaining square-drive is disclosed consisting primarily of a lever mounted on the shaft of a typical ratchet-driven socket wrench parallel to the shaft. A flat fork in one end of the lever is placed around the square-drive at its base and under a retained socket. A fulcrum at the midpoint of the lever rests on the shaft of the wrench and the lever is retained by a spring clip surrounding both the lever and the shaft. Depression of one end of the lever raises the fork end lifting the socket from the square drive and the spring clip returns the lever to its initial position.
