摘要： A drain cleaning machine including a machine body with a drive assembly, rotary drum having a flexible shaft wound therein, and lead frame guiding the flexible shaft to advance and retract; the lead frame includes an inner base, outer cylinder, and locking structures; the lead frame includes an inner base, an outer cylinder, and locking structures; each locking structure includes a slider, a rotary member, and an elastic member; the outer cylinder is provided with abutting sections. The drain cleaning machine reasonably simplifies the structure of the lead frame by reasonably setting the specific structures of the lead frame and the locking structures, where the slider may drive the rotary member to move towards or away from the flexible shaft via forward/reverse rotation of the outer cylinder, which facilitates user operation.

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 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.
