发明名称 Hose coupling member repair tool
摘要 A tool for repairing out-of-round coupling members on a garden hose. A pair of essentially identical levers are pivoted together. Each of the levers is configured as a partially cylindrical nose, a curved jaw and an elongated handle. The noses can be inserted in the coupling swivel (female coupling member) or the nipple (male coupling member) can be inserted in openings in the jaws when the handles are moved apart. The coupling swivel or nipple, as applicable, can be partially reshaped with the tool by moving the handles together.
