die entsprechende Schlitzwand anlegt. In geschlossenen Bohrungen w des Körpers a liegen Federn tt, die auf Stifte n' einwirken, welche nach dem Schlitz zu vorstehen und vorn auf den Klemmkörper drücken. Diese federbelasteten Stifte n' wirken derart schräg auf die radial stehenden Seitenflächen der Klemmkörper ein, dass letztere sowohl radial nach aussen gegen die Exzenterflächen, als auch seitlich gegen die entsprechenden Schlitzwandungen gedrückt werden.
Bei dem gezeichneten Beispiel ist angenommen, dass der Bohrer im Betriebe im Uhrzcigerfiunc umtauft, also in der Richtung des Pfeiles in Fig. 2. Die Feder drückt also entgegen dieser Bewegungsrichtung gegen die Schlitzwand.
Unterhalb der Ansätze k sind ebenso geformte Ansätze g', h' und i' an der Rückseite des Klemmkörper vorgesehen, welche sich gegen die Exzentonächen der Hülse legen. Wie nn aus Fig. 4 erkennt, hat der Klemmkörper h nur einen Ansatz h', welcher mit dem Exzenter e zusammenwirkt. Die beiden anderen Backen g und i haben je zwei Ansätze i' bzw. g', wobei

creates the corresponding diaphragm wall. In closed bores w of the body a there are springs tt which act on pins n 'which protrude towards the slot and press the front of the clamping body. These spring-loaded pins n 'act obliquely on the radially standing side surfaces of the clamping bodies in such a way that the latter are pressed both radially outward against the eccentric surfaces and laterally against the corresponding slot walls.
In the example shown, it is assumed that the drill is renamed in operation in the clockwise function, that is in the direction of the arrow in FIG. 2. The spring thus presses against the direction of movement against the diaphragm wall.
Below the projections k, similarly shaped projections g ', h' and i 'are provided on the rear side of the clamping body, which rest against the eccentric surfaces of the sleeve. As nn from FIG. 4 recognizes, the clamping body h has only one shoulder h ', which cooperates with the eccentric e. The other two jaws g and i each have two approaches i 'and g', where
