A drive unit for a pipe cleaning or sewer augering machine includes a chuck for the flexible shaft or plumber's snake of the pipe cleaning machine, the chuck having jaws for detachably clamping the flexible shaft to the chuck which, in turn, also transmits driving torque to the flexible shaft and which is operably connected to the driving means, the jaws being disengageable from the carrier of the chuck. |
