摘要： The system disclosed herein is directed to a plunger adapted for use with a protective sleeve for shielding contaminants from the plunger. In one example, a plunger has a handle having a first end and a second end. A flexible cup is coupled to the first end of the handle. The flexible cup has an interior surface and an exterior surface. An inlet is disposed on the exterior surface of the flexible cup. A through-hole is located in the flexible cup offset from the inlet. A connector is coupled to the inlet between the flexible cup and the handle. The connector is configured to join the first end of the handle to the flexible cup.

摘要： Various drop head coupling assemblies are described. The coupling assemblies enable a drop head tool typically used in drain cleaning operations to be releasably engaged with a drain cleaning cable. The coupling assemblies enable the drop head tool to undergo a wide range of motion relative to the drain cleaning cable, particularly during rotation of the cable and drop head.

摘要： 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.

摘要： A plumbing snake assembly includes a drill has a handle, a motor housing, a chuck is positioned on the motor housing and a drive unit is positioned within the motor housing. The motor housing has a cable aperture extending therethrough. A plurality of flexible shafts is provided and the flexible shafts can be coupled together to form a plumbing snake for pushing through a drain pipe. Each of the flexible shafts is insertable through the cable aperture in the drill such that the drive unit engages and subsequently rotates the flexible shafts when the drive unit is turned on. A cleaning head is removably attachable to a respective one of the flexible shafts thereby facilitating the cleaning head to be positioned on a leading end of the plumbing snake defined by the flexible shafts. In this way the cleaning head engages and removes a blockage in the drain pipe.

摘要： A drain cleaning cable for use with a drain cleaner. The drain cleaning cable includes an inner core having a first end and a second end, and an outer wire concentrically surrounding the inner core, where the outer wire is helically wound in a first direction to form a plurality of consecutive coils, and where the outer wire has a first end and a second end. A first connector engages with the first end of the inner core and the first end of the outer wire, where the first connector is configured to attach the drain cleaning cable to a drain cleaning element. The second end of the inner core and the second end of the outer wire are received within the drain cleaner.
