Abstract

Die Erfindung betrifft einen Drehmomentschlüssel mit zwischen Betätigungshandhabe (1) und Schraubwerkzeug angeordneter, bei Überschreiten eines bestimmten Drehmo­ ments in Freigangstellung tretender Sperreinrichtung und bezweckt, einen Drehmomentschlüssel dieser Art so auszu­ bilden, daß nur die mit dem erforderlichen Drehmoment hergestellten Schraubverbindungen eine optische Markie­ rung erhalten, was in baulich vorteilhafter Weise dadurch erreicht wird, daß im Bereich der Sperreinrichtung ein bei Übertritt in die Freigangstellung betätigter Impulsgeber (24) und im Bereich des Schraubwerkzeugträgers (4) eine vom Impulsgeber (24) gesteuerte Farbspritzpistole (8) angeordnet ist, deren Spritzstrahl in den Angriffsbereich des Schraub­ werkzeugs gerichtet ist. The invention relates to a torque wrench between operating handle (1) and screwing tool arranged, when a certain torque is exceeded locking device and aims to turn a torque wrench of this type form that only with the required torque manufactured screw connections an optical markie tion obtained, which is structurally advantageous is achieved in that in the area of the locking device Transition to the activated position of the pulse generator (24) and in the area of the screw tool carrier (4) one of Pulse generator (24) controlled paint spray gun (8) arranged is, the spray jet in the attack area of the screw tool is directed.
