Abstract
A quick coupling for coupling a tool to the boom of a hydraulic excavator and the like with a quick coupling part at the boom side and a quick coupling part at the tool side which can be latched together via a pair of spaced latching axles and with a power circuit coupling, in particular a hydraulic coupling, for the automatic coupling of a power connector at the tool side to a power connector at the boom side, wherein the power circuit coupling has a power coupling part at the boom side and a power coupling part at the tool side which ar arranged at the quick coupling part at the boom side or at the quick coupling part at the tool side such that they automatically couple as soon as the two quick coupling parts are pivoted together into their latching position about a first of the two latching axles. The quick coupling is characterized by a linear guide being associated with the power circuit coupling which guides the two power coupling parts in a linear manner with respect to one another during coupling despite the pivot movement.
