The invention relates first to a hand tool, including a working head, which is actuated by an electric motor and/or by a hydraulic medium and which has a working part, and including a sensor for detecting a spatial motion, wherein the working part travels through a motion sequence as the result of a first triggering by a user in order to perform a working process. In order to specify a hand tool that allows a reliable series of actuations at differential spatial orientations of the tool to be achieved, according to the invention an additional triggering is possible only if the working part has ended the motion sequence resulting from the first triggering and the tool has been spatially moved overall thereafter. The invention further relates to a hand expansion device for expanding pipe ends, including an expanding head, which can be actuated by an electric motor and/or by a hydraulic medium and which has a plurality of segments, wherein the segments, which can be actuated by a spreading mandrel hat can be moved in the direction of a longitudinal axis of the expanding head, can be spread transversely to a movement direction of the spreading mandrel as the result of a first triggering of an expansion process. |
