Abstract
The coupling device for coupling a cable of a sewer and drain cleaning machine to a cutting tool comprises a housing, a cable connecting mechanism for connecting the cable to the housing, a cutting tool connecting mechanism for rotatably connecting the cutting tool to the housing, and a breakable drive mechanism for driving the cutting tool when the cable and the housing are rotated and breaking when a predetermined amount of torque is applied between the housing and the cutting tool, the predetermined amount of torque being less than the amount of torque needed to break the cable.
