Nach Auswechselung der Pressbacken f gegen die in Fig. 5 dargestellte Armatur mit dem schwingenden Messer 1n kann das Instrument, wie ohne weiteres verständlich als Rohrschlitzer oder Perforierinstrument gebraucht werden.
Der Vorteil des beschriebenen Instrumentes liegt ebensowohl in der Einfachheit und Sicherheit, mit welcher dasselbe nach dem Gebrauch in beliebiger Tiefe gelöst werden kann, als auch in der billigeren Herstellung, namentlich des Hauptkörpers a und der bedeutenden Vereinfachung wegen des Gebrauches von nur zwei Backen.
Von den bisher bekannten Rohrkrebsell, bei welchen ebenfalls zwei gezahnte Klemmbacken mittels eines Ringes aufgehängt sind, welche Backen durch einen vierkantigen mit zwei ebenen schrägen und zwei parallelen Seitenflächen versehenen Körper auseinander gespreizt werden, unterscheidet sich die vorliegende Vorrichtung dadurch, dass die beiden schrägen Flächen

für die mit entsprechenden Anliegefläche ausgestatteten Backen versehen sind, so dass der Apparat durch einfaches Drehen am Gestänge aus der geklemmten Stellung gelöst werden kann.

After exchanging the pressing jaws f for the armature shown in FIG. 5 with the oscillating knife 1n, the instrument can, as is easily understood, be used as a pipe slitter or a perforating instrument.
The advantage of the instrument described lies in the simplicity and safety with which it can be loosened to any depth after use, as well as in the cheaper production, namely the main body a and the significant simplification due to the use of only two jaws.
The present device differs from the previously known pipe crab, in which two toothed clamping jaws are also suspended by means of a ring, which jaws are spread apart by a square body provided with two flat inclined and two parallel side surfaces, the present device differs in that the two inclined surfaces

for the jaws equipped with the appropriate contact surface, so that the device can be released from the clamped position by simply turning the rod.
