A multifunction pliers tools to fit clamp-type products, with its unique characteristic to be possibly applied to several application fields, such as building construction and also medicine filed, where it achieves aggregating at the same product one application function； a tensioning function； a cutting function and a finishing function, and to get that a multifunction pliers product (1) was developed and is composed by a right lever component (A)； a left lever component (B)； a tension regulator pin component (C)； a fitting cylinder component (D)； and a assembly pin component (E), being in particular its functional concept is understood by the segmentation in four steps: the first one named clamp application； the second step named clamp tensioning； the third step named clamp folding and the fourth step named clamp segment cutting with finishing of the obtained edges.
