Abstract

The rod directly or indirectly via one or more intermediate coupling parts, can work in conjunction with a tool. It works in conjunction with a rotator, which has a rotation axis which coincides with a common plane for the boom and bar. A first coupling device, incorporating a first rotator-related coupling unit and a second rod-related coupling unit, is arranged to retain the rotator to the rod. A second coupling device, incorporating a second rotator-related coupling unit and a first tool-related coupling unit, holds the tool to the rotator. The second rotator-related coupling unit is rotatably fitted to the rotator. The necessary rotating axis is edge-related to the rotator and orientated at right-angles in relation to the common plane for the boom and the rod.
