又叫basin wrench，用途是“Tightening/loosening nuts and hose couplings under sinks and lavatories”

Wikipedia的解释是“a self-tightening wrench mounted at the end of a torque tube with a transverse handle at the opposite end. Used to tighten tubing connections to washstand valves in ceramic sinks—the nuts are often located deep in recesses. The self-tightening head may be flipped over to loosen connections.”

以老兄的经验看，用这个东西会更方便么？
