Abstract
A versatile cleaning-used duster broom structure comprises a dusting broom body composed of elastic soft bristles to fit to a coupling seat equipped with a handle. The coupling seat has an opening end to which the dusting broom body is accommodated and located thereto. The opening end has multiple conjoining blocks each defined by an insert groove thereon, and the dusting broom body has the surface bundled up into a collecting portion so that the elastic soft bristles can be more evenly arranged to match to a fixing pole thereby. Besides, each elastic soft bristle has multiple individual cellular suction portions, forming an elastic and dense bristle surface thereon to suck up fine particles of dust thereby. Thus, via the stretchable character of the suction portions thereof, the elastic soft bristles can accurately enwrap trash and clean up sand, dust and hair, etc., providing effective and effortless cleaning benefit thereby.
