The draughting head has a locking unit with abrake, Ruler retainers, retainer plate, and grip knob form a group and are held in a base plate carrying the angle dividing ring so that they can rotate. A ratchet with a brake section, on the carrier plate acts with a locking disc and brake disc on the base plate. A thumb lever (14) is pivoted within the hollow grip knob (13). A first movement of the lever actuates the locking system (16), and a second, different movement operates the fixing brake (15), via an intermediate element, e.g. a rack drive (41, 43).
