Abstract
Description
Die Erfindung betrifft ein drehmomentverstellbares Werkzeug, bei dem das Abtriebsdrehmoment teilweise oder vollständig übertragen werden kann.The The invention relates to a torque-adjustable tool in which the output torque can be transmitted partially or completely.
Bei einem herkömmlichen Handwerkzeug zum Ergreifen eines Gegenstandes, zum Beispiel einer Schraube, die in einer tiefen Ausnehmung liegt, wird im Allgemeinen eine Verlängerungsstange verwendet, deren eines Ende mit dem Antriebs- oder aktiven Teil zum Übertragen der Kraft auf die Verlängerungsstange verbunden ist und deren anderes Ende zum Beispiel mit einem Schraubeinsatz zum Drehen des Gegenstandes verbunden ist. Dennoch könnte der Gegenstand teilweise überdreht werden, da der Abstand, in dem die Kraft zu übertragen ist, zu lang ist, so dass die Bedienperson mit deren Hand nicht genau die Wirkung des Widerstandes von dem Gegenstand fühlen kann. Obwohl ein drehmomentverstellbares Werkzeug wenigstens das Abtriebsdrehmoment unter einem vorgegebenen Wert hält, ist das Werkzeug jedoch unnötig, wenn die Bedienperson keine Begrenzung des Abtriebsdrehmoments braucht. In dieser Situation muss die Bedienperson ein anderes Werkzeug benutzen, das keinerlei Begrenzung des Abtriebsdrehmoments aufweist.at a conventional one Hand tool for gripping an object, for example a Screw that lies in a deep recess will generally an extension bar used one end of which with the drive or active part to transfer the force on the extension rod is connected and the other end, for example, with a screw connected to rotate the object. Nevertheless, the Object partially overrun because the distance in which the force is to be transmitted is too long, so that the operator with their hand is not exactly the effect of the resistance of the object. Although a torque adjustable Tool at least the output torque under a predetermined Value, if the tool is unnecessary, when the operator does not need to limit the output torque. In this situation, the operator has to use another tool, which has no limitation of the output torque.
Das drehmomentverstellbare Werkzeug gemäß der Erfindung weist ein aktives Teil mit einem ersten Kupplungsabschnitt auf, der mit einem zweiten Kupplungsabschnitt eines passiven Teils in Eingriff steht. Eine Sicherungsvorrichtung ist an dem aktiven Teil und dem passiven Teil montiert. Die Sicherungsvorrichtung weist ein Steuerteil auf, wobei eine Feder zwischen dem Steuerteil und dem ersten und dem zweiten Kupplungsabschnitt angeordnet ist. Eine Verriegelungsvorrichtung weist ein Verriegelungsteil auf, welches das aktive Teil zu einer Einheit mit dem passiven Teil verriegelt.The torque adjustable tool according to the invention has an active Part with a first coupling portion, with a second Coupling portion of a passive part is engaged. A Securing device is on the active part and the passive part assembled. The safety device has a control part, wherein a spring between the control part and the first and the second Coupling section is arranged. A locking device has a locking part, which the active part to a Unit locked with the passive part.
Die Erfindung wird mit Bezug auf die Zeichnung näher erläutert. In der Zeichnung zeigen:The The invention will be explained in more detail with reference to the drawing. In the drawing show:
