    摘要: The hand-held power tool has a vibration-damped main handle. The hand-held power tool has a device for fastening the main handle to a main element configured so that when the main element moves out of a stationary position toward the main handle the main element swivels around at least one swivel axis so that it is guided along a trajectory that extends with a slant of at least 10° relative to a flat surface, which extends through a longitudinal tool axis and which has a surface normal oriented in a normal direction perpendicular to the longitudinal tool axis. As a result vibrations with a movement component perpendicular to the longitudinal tool axis are damped as well as vibrations that induce motion of the main element in the direction of the longitudinal tool axis toward the main handle.

    摘要: The invention relates to a portable power tool for a rotating, preferably disk-shaped tool (12). Said portable power tool comprises a machine housing (14), having a flange (16, 160) or a machine neck, and a protective hood (18) that can be detachably tensioned on the machine neck to cover the tool (12) or that has a protective hood neck (20) or protective hood collar that annularly carries a tightening strap (22). Said strap can be tightened by tensioning means (24). An anti-rotation lock effective between the machine neck and the protective hood (18) is interposed between the protective hood (18) and the machine neck in the form of a profiled structure (26). The invention is characterized in that the tensioning means (24), in its tensioned position, can be connected several times in a form fit to the machine neck and in its detached positioned is no longer connected in a form fit to the machine neck.
