发明名称 Rain gutter cleaning tongs
摘要 Rain gutter and downspout cleaning tongs. The rain gutter cleaning tongs include a pair of arms, each having a distal portion and a proximal portion that are arranged at obtuse angles relative to each other. A gripping head is located at a distal end of the distal portion of each arm. The proximal arm portions are pivotally attached to each other and are spring loaded to bias their gripping surfaces away from each other. Optionally, a guide is attached to one of the arms for guiding the two arms relative to each other during operation.
