Abstract
An arresting device for force-transmitting fixing of two relatively movable parts, particularly for cutting angle or cutting depth adjustment of electric hand saws, the arresting device has a pin having a radially extending pressing surface for pressing against one of the parts, a clamping element having a pressing surface for pressing against another of the parts and arranged on the pin so that by a relative turning of the clamping element and the pin the pressing surfaces are moved toward one another for producing a clamping and from one another for releasing the clamping. The clamping element is formed as a hand lever having a clamping sleeve and a lever arm extending from the clamping sleeve. The clamping sleeve is turnably arranged on the pin and has a clamping collar extending over the lever arm and provided with a ring-shaped end surface forming the pressing surface of the clamping element. The pin has an outer peripheral surface provided with at least one depressed cam path having a path starting portion at a free pin end and a path end facing the pressing surface of the pin. The cam path has a pitch which starting from the path starting portion reduces in a peripheral direction toward and to the path end. A a guiding pin extends radially in the clamping sleeve and engages in the at least one cam path.
