    Abstract: A tool for making a plug connection between a plastic tube and a plastic case for electrical conductors has a cutting head which is designed to encircle the shell of a tube and which can be turned relatively to the tube. Extending into the interior of the cutting head is a first knife for chamfering the end of the tube as well as a second knife, at a distance from the first, for cutting a fircone-shaped rib in the shell of the tube. The cutting head is firmly connected to one end of a bar-shaped handle, which is provided at its other end with a bore head for making a hole in the wall of the case. The bore head comprises a cutter on an end of a steel hollow cylinder connected at its other end to the handle and projecting out from its respective front end. A protective and centering plunger is slidable against the effect of a spring within the hollow cylinder coaxially with the handle, the plunger forming on its free end a pressure plate which, in the normal state of the tool, projects above the cutter on the hollow cylinder.

    Abstract translation: 用于在塑料管和用于电导体的塑料外壳之间进行插头连接的工具具有切割头,该切割头被设计成环绕管的外壳并且可相对于管转动。 延伸到切割头的内部是用于倒角管的第一个刀,以及与第一个刀片相距一定距离的第二个刀片,用于切割管的外壳中的圆锥形肋。 切割头牢固地连接到杆形手柄的一端,该杆状手柄的另一端具有用于在壳体的壁中形成孔的孔头。 孔头包括在其另一端连接到手柄并从其相应的前端突出的钢中空筒的端部上的切割器。 保护定心柱塞可抵抗弹簧与手柄同轴的弹簧的作用滑动,柱塞在其自由端上形成压板,该压板在工具的正常状态下在中空圆筒上的切割器上方突出 。
