Pliers, with two handles, one male (1) and another female (2) that are joined to each other by a joint bolt (3); where: the bolt (3) presents its reduction (31) centered and accompanied by two was (31a), (31b) which are housed in the orifice-housings (20); the spline (4) and the orifice-housing (5) are conjugated with each other and coaxial with the bolt itself (3); the spline (4) defines two corners (4a), (4b) opposite each other, to fit without turning in the orifice-housing (5), with conjugated shape; the female handle (2) defines a wall (2a) whose width is at least equal to the height of the spline (4): and the stud bolt (6) is threaded in the orifice (40) of the spline (4); the bolt (3) defines an eccentric orifice (40) with two zones (40a), (40b) of different sections; the last threaded, the means to prevent the turning of the bolt (3) with respect to the female handle (2) are an eccentric stud bolt (6) with two zones (60a), (60b) conjugated with those of the eccentric orifice (40) where it is mounted. |
