Abstract: A drum-type pipe cleaning device comprises a drum rotatable about a rotational axis and a cleaning cable allocated to the drum. A longitudinal section of the cleaning cable extends from the drum. The longitudinal section is rotatable about its longitudinal axis through a rotation of the drum. The drum-type pipe cleaning device further comprises a handle, which is configured to support the drum in a rotatable manner. Furthermore, the drum-type pipe cleaning device comprises a drive shaft for driving the drum and an attachment point allocated to the drive shaft for connecting the drive shaft to a drive unit for drive purposes. A freewheel clutch is provided, through which the drive shaft is or can be connected to the drum in an operative manner such that the freewheel clutch is engaged when the drive shaft is being driven and the freewheel clutch runs freely when the drum is being driven.

Abstract: A cutting device for the chipless cutting of a material comprises a cutting part and a supporting part. The cutting part and the supporting part are designed to be rotated with respect to one another about an axis of rotation between an open position and a closed position. A hand lever is articulated to the supporting part for pivoting about a pivot axis. A ratchet mechanism converts a back-and-forth motion of the hand lever into a continuous rotational motion of the cutting part toward the closed position. The ratchet mechanism includes a toothing and a drive pawl, which can be brought into an effective position with respect to the toothing. Furthermore, the cutting device comprises a coupling mechanism, which converts a one-time pivoting motion of the hand lever into a rotational motion of the cutting part. A separate coupling element transmits force from the hand lever to the cutting part.
