发明名称 BIDIRECTIONAL PIPE BENDING PLIERS
摘要 A pair of bidirectional pipe bending pliers comprises: a first handle and a second handle. The first handle includes a first handle portion and a first pipe-bending portion, and the second handle includes a second handle portion and a second pipe-bending portion. When the first and second pipe-bending portions are closed toward each other to carry out clamping operation, the first and third bending grooves will define a first pipe-bending path therebetween, while the second and fourth bending grooves will also define a second pipe-bending path, the first and second pipe-bending paths extend in different axial directions.
