   Es ist bekannt, bei Handdrehbohrmaschinen die Bohrspindel mit ihrem Antrieb verstellbar auf dem Stützhebel anzuordnen. Bei dem mit fortschreitender Bohrarbeit notwendigen Nachneigen des Stützhebels muss daher das Lager der Bohrspindel an diesem Hebel besonders verstellt werden, um die Achsenrichtung der Bohrmaschine beizubehalten. Diesen Übelstand zu beheben ist der Zweck der Erfindung und besteht diese darin, dass die Bohrmaschine mittels eines Kniegelenkes am Stützhebel gelagert ist, so dass das Nachneigen des Stützhebels den starr mit der Bohrspindel verbundenen Arm des Kniegelenkes unverändert lässt und nur den Lenkarm des Kniegelenkes verstellt. 



   In der Zeichnung sind zwei Ausführungsformen dieser Vorrichtung dargestellt. Gemäss dem in den Fig. 1 und 2 in Seitenansicht und im Grundriss dargestellten Beispiele ist auf dem Stützhebel 15   eine Muffe. ?   mittels Daumenhebels 17 feststellbar. An der Muffe sind die beiden Hebel 18 drehbar gelagert, auf dem die Enden dieser verbindenden Bolzen 19 sind auch die Stangen 20 drehbar aufgesteckt, die von den Federn 21 entsprechend hochgehalten werden. An den Enden der Stangen 20 ist der Bohrkopf mit Antrieb angeordnet. Die Arme 18 und 20 des Kniegelenkes liegen beispielsweise beim Anstellen

 Lage und nur der Lenkerarm 18 des Kniegelenkes wird eine veränderte Lage einnehmen. 



   Das in den Fig. 3 und 4 in Seiten-und Stirnansicht dargestellte Ausführungsbeispiel zeigt ein Kniegelenk, das aus dem gekröpften Arme 13 und dem in diesen eingehängten Arme 12 gebildet ist, welcher den   Antriebsmeehanismus   mit Bohrkopf trägt. Der Arm 13 kann in bekannter Weise in verschiedener Höhe an dem   Stützhebel 10   drehbar eingehängt werden und wird auch hier bei fortschreitender Bohrarbeit und veränderter Lage des Stützhebels die Achsenrichtung der Bohrmaschine beibehalten.

 EMI1.1
 



   It is known to arrange the drill spindle with its drive on the support lever so that it is adjustable in hand-held drilling machines. When the support lever is tilted as the drilling work progresses, the bearing of the drilling spindle must therefore be specially adjusted on this lever in order to maintain the axial direction of the drilling machine. The purpose of the invention is to remedy this inconvenience and consists in the fact that the drill is mounted on the support lever by means of a knee joint, so that the tilting of the support lever leaves the arm of the knee joint rigidly connected to the drill spindle unchanged and only adjusts the steering arm of the knee joint.



   In the drawing, two embodiments of this device are shown. According to the example shown in side view and in plan in FIGS. 1 and 2, there is a sleeve on the support lever 15. ? lockable by means of the thumb lever 17. The two levers 18 are rotatably mounted on the sleeve, on which the ends of these connecting bolts 19 are also rotatably slipped on the rods 20 which are held up by the springs 21 accordingly. The drill head with drive is arranged at the ends of the rods 20. The arms 18 and 20 of the knee joint are, for example, when hiring
 EMI1.2
 Position and only the link arm 18 of the knee joint will assume a changed position.



   The embodiment shown in FIGS. 3 and 4 in side and front view shows a knee joint which is formed from the cranked arm 13 and the arm 12 suspended in this, which carries the drive mechanism with the drill head. The arm 13 can be hung rotatably in a known manner at different heights on the support lever 10 and here too the axial direction of the drilling machine is maintained as the drilling work progresses and the position of the support lever changes.
