发明名称 Electric hand tool-in particular an angle sander/grinder
摘要 The invention relates to an electrical hand tool device, in particular an angle grinder with a machine housing for holding a motor for the rotating drive of a drive shaft and a driven shaft connected with it via an angular gear for attaching a grinding tool at its free end, whereby a protective guard (12) that surrounds the grinding tool with a base body (14) at least partially and exhibits a protective guard neck (16) that is connected to the base body (14) and that can be detached together with said protective guard neck at a flange (20), which is positioned at the machine housing, and can be secured and locked in discrete adjustable rotational positions at the flange (20), whereby the protective guard (12) can be secured and locked at the flange (20) in a rotational position using a notch lever (18), and where for this purpose a ratchet cam (42) at the notch lever (18) reaches through an opening (40) in the protective guard (12), where a pivoting axis (22) of the notch lever (18) is arranged parallel to the driven shaft and the opening (40) is located in the protective guard neck (16) of the protective guard (12).
