Abstract
A hand power tool has at least one safety coupling arranged in a drive train, the safety coupling having at least two coupling elements for transmitting a torque around a rotary axis, at least one arresting element which is spring loaded and held in a guiding passage for connecting the coupling elements with one another, a guiding element, a spring providing spring-loading of the arresting element and supported in direction of the arresting element by the guiding element, the guiding element being non rotatably guided relative to an axis extending parallel to the rotary axis by guiding surfaces in the guiding passage, and the arresting element unlatching and keeping in contact with a surface toward which the arresting element is urged by the spring in response to exceeding of predetermined torque.
