Abstract:
1. A combination comprising, in combination: a wrench including a head having a drive portion adapted to drive an object, with the wrench further including a handle having a first end interconnected to the head and a second end spaced from the first end along a longitudinal axis, with the second end of the handle including a first receptacle extending in a radial direction perpendicular to the longitudinal axis; an extension including a tubular member defining a longitudinal hole, with the second end of the handle slideably received in the longitudinal hole along the longitudinal axis, with the tubular member having inner and outer peripheries spaced in the radial direction, with the tubular member further including a positioning hole extending from the inner periphery through the outer periphery of the tubular member and in communication with the longitudinal hole; a first positioning member mounted in the first receptacle, with the first positioning member including a body and first and second sections, with the second section intermediate the first section and the body in the radial direction, with the body slideably received in the first receptacle in the radial direction, with each of the first and second sections having first and second ends spaced in the radial direction, with the first end of the second section interconnected to the body, with the second section having an outer diameter smaller than the body and larger than a diameter of the positioning hole, with the first end of the first section interconnected to the second end of the second section, with the first section having an outer diameter smaller than the second section, with the first section slideably extending through the positioning hole in the radial direction; and a first spring received in the first receptacle, with the first spring biasing the first section of the first positioning member to extend through the positioning hole with the second end of the first section outside of the tubular member, coupling the second end of the handle with the tubular member, with the second end of the second section pressing against the inner periphery of the tubular member, with the second end of the first section being pushable in the radial direction to disengage from the positioning hole allowing disengagement of the tubular member from the second end of the handle.
