Pliers are provided to facilitate the lever working by preventing foreign matter and rust from being fitted or occurred between the first connection part and the second connection part. Pliers comprise a first tool part(110) consisting of a first grip part(111), a first working part(112), and a circular first coupling part; and a second tool part consisting of a second grip part(121), a second working part(122), and a circular coupling part(123). The second tool part is joined together with a first tool part. A plurality of recesses(113-1) are formed along the circumference of the inner lining of the first coupling part of the first tool part. An annular groove(123-1) is formed along the inner circumference of the second coupling part of the second tool part. A ball(140) is formed between the recessed groove and the annular groove. |
