Embodiment Construction

[0030] figure 1 Shown is a hand-held power tool 100 equipped with a tool receptacle 150 , which has a tool housing 110 with a handle 126 and is designed, for example, as a rechargeable rotary impact driver. According to one specific embodiment, hand-held power tool 100 can be mechanically and electrically connected to battery pack 130 for a grid-independent supply of current, for which alternatively, for example, it can also be operated grid-dependent.

[0031] However, it is pointed out that the invention is not restricted to battery-rotary impact drivers, but rather can be used in different electric tools in which (for example in screwdrivers, drill drivers, impact drivers, etc.) drilling rigs, etc.), the tool is set in rotation, irrespective of whether the power tool can be operated independently of the grid with a battery pack or in a grid-dependent manner. Furthermore, it is pointed out that the invention is not restricted to motor-operated hand-held power tools, but can...
