An automatic spindle arresting device for hand tools, especially for drills, drill screwdrivers, angle grinders and the like, with a latching part (50; 120), which is connected to the spindle (20) or the housing (10) so that there cannot be any mutual rotation, and which can be coupled in both direction of rotation of the spindle (20) with at least one arresting part (40; 140), which is connected with the housing (10) or the spindle (20) so that there cannot be any mutual rotation, and with a driving part (34; 110), which is disposed equiaxially to the spindle (20) and has unlocking elements, by means of which the latching part (50; 120) and the arresting part (40; 140) can be uncoupled, is characterized in that the unlocking elements are one or more control paths (38; 116), which are disposed at the driving part (34; 110) and at which one or more control cams (54; 124) of the latching part (50; 120) slide due to a rotational motion of the driving part (34; 110) in such a manner, that the latching part (50; 120) and the arresting part (40; 140) can be uncoupled by an axial shifting either of the latching part (50; 120) and/or of the arresting part (40; 140). |
