Interchangeable tool e.g. grinding plate, for use with handheld machine tool for processing workpiece, has auxiliary retainer provided in flange region and including polarity opposite to retainer, which is designed as form-fit element

摘要

The tool (114) has an actuator (112) designed as a form-fit element, which includes a positive polarity or a negative polarity and is elevated above a fixing plane (151) or immersed in the fixing plane. A retainer (112') i.e. opening, is designed as another form-fit element, which is lifted above a flange plane (146) or immersed in the flange plane, and corresponds to the positive polarity or the negative polarity. An auxiliary retainer (152) is provided in a flange region (144), and includes a polarity opposite to the retainer. Independent claims are also included for the following: (1) a tool holder (2) a motor-driven hand tool.
