ABSTRACT:
An assembly for coupling a maneuvering member to a working implement generally consisting of a first coupling component mountable on the working tool, a second coupling component mountable on the maneuvering member and cooperative with the first coupling component for selectively coupling the coupling components together, the first coupling component having an annular undercut portion providing an outwardly facing, beveled gripping surface, the second coupling component having a fixed gripping member and a moveable gripping member displaced relative to the fixed gripping member along a line of travel, the gripping members having arcuate undercut portions providing inwardly facing, beveled gripping surfaces engageable with the outwardly facing, beveled gripping surface of the second coupling component, means for selectively displacing the moveable gripping member relative to the fixed gripping member along the line of travel into a fully coupled condition of the coupling components and a fully uncoupled condition of the coupling components, latch means for restricting the displacement of the moveable gripping member relative to the fixed gripping member into a partially uncoupled condition insufficient to permit removal of said second coupling component from the first coupling component yet sufficient to permit a rotational displacement of the coupling members relative to each other and means for selectively displacing the latch means.
