Patent attributes
A cable feeding device for a drain cleaner includes an upper body mounted on a support tube of the drain cleaner, a control subassembly, and a lower body. The upper body in which an upper feeding roller is held and the lower body in which two lower feeding rollers are held join each other, so that a cable inside a cable drum of the drain cleaner can extend through a region encircled with the upper and lower feeding rollers and can be resisted by the upper and lower feeding rollers for controllable forward or backward movements of the cable into a drain to be cleaned. The lower body has at least one separate mold-stripping hole for easy manufacturing of the upper and lower bodies in a plastic injection molding process. The upper and lower feeding rollers are not exposed to the outside for longer service life to hold the cable.
