<p>A tool for loosening and tightening of nuts, especially wheel nuts, has an integral planetary gearing to connect the input shaft (5) to the output shaft (19) via sockets connected to both shafts. The outer ring of the planetary gearing is bonded to the housing and the input shaft is connected to the ring gear via a movable hand grip (9). The tool is braced against the wheel rim and provides high torque as well as a rapid threading action.</p> |
