发明名称 Rotating machine, approximately in the form of a hand drill, a percussion drill, a drill hammer or a battery screwdriver
摘要 The invention relates to a tool-receiving element, the tool-clamping device thereof being directly integrated into the rotating machine. A multiple-edge longitudinal recess (21,121,221), especially a hexagonal recess, extends into the drive shaft (18,118,218) from the output-side front end thereof. A clamping sleeve (25,25',125,225) is received on the section of the drive shalt comprising the tool-receiving element, in the form of a tool-clamping device, by which means at least one locking element (24,124,224) received in a radial recess penetrating the shell of the tool-receiving element can be actuated in a locking position protruding radially into the tool-receiving element, and can be released in an unlocking position for radial yielding.
