ABSTRACT:
The holder releasably receives and holds a rechargeable tool portion and is associated with a cable electrically connecting the tool portion for line-powered operation or battery-powered operation with a current source. The holder has a shell-like rest enclosing a lower portion of the tool portion and is structured to be changeable from a first configuration, in which the tool portion is supported by the holder and is removable for battery-powered operation, to a second configuration, in which the tool portion with the holder attached can be used for line-powered operation. The holder has a first leg extending longitudinally along a larger part of one side of the tool portion when the tool portion is in the holder, a second leg pivotally connected to one end of the first leg and acting as a supporting limb and a spreading spring connected to the second leg to urge the second leg from the first leg into a spread position so the tool portion and holder can stand together on a surface during battery charging. The second leg is provided with a plurality of catches engagable in cavities in the tool portion when the second leg is engaged with the first leg to form a compact structure together with the tool portion during line-powered operation.
