Abstract

A battery-driven handtool is configured with a holder (4) for housing the current source, this housing being detachably connected to the handgrip (1) of the tool. The holder is journalled for asymmetric rotation (around A) on the free end of the handgrip, so as to enable the outer dimensions of the tool to be minimized, by causing the holder to take at least two mutually opposing positions when the working space is confined, thereby also enabling the center of gravity point (TP) of the tool to be changed.
