Title: Device for rapid tool coupling and release on tool arms

Abstract: The device for rapid tool coupling and release on tool arms comprises afirst rapid-attachment organ associated to a tool arm and is provided withat least one tooth and with hollow coupling seatings destined to couple inseatings and also with at least one pivot predisposed on the tool. Therapid-attachment organ is provided with at least a portion of couplingsurface destined to couple on contact with at least a portion of plane onthe seatings; the coupling surface is oriented in such a way that aperpendicular thereof does not intersect an axis of the pivot coupled in ahollow seating. Each of the at least one tooth of the coupling element,which is axially mobile internally of a guide having an axis lying in aperpendicular plane to the axis of the pivot coupled in a hollow seating,has an inclined plane destined to couple with a corresponding flat surfaceafforded on the at least one seating; the inclined plane being inclinedwith respect to the axis of the guide and generating together with theaxis of the guide a slight tapering of a free end of the at least onetooth destined to couple by insertion thereof in the at least one seating.
