Wrench socket retainer
 A detent mechanism for releasably retaining a wrench socket on the rotary drive member of an air impact wrench. A push rod is provided within the wrench body to normally support a ball detent in a locking position projecting from a side surface of a drive member plug portion that is adapted to extend into a wrench socket. Manual push motion on a rear end of the rod causes a pocket in the side face of the push rod to register with the ball detent for enabling the detent to retract into the plug portion of the drive member.
