Abstract:
1. Pliers, comprising: two handles, one male and another female, that are joined to each other by a joint bolt; the male handle defines a slotted window, of straight or curved configuration, the walls of which carry teeth or grooves; along said slotted window the female handle can reach different working positions to vary the fastening capacity of a mouth of the pliers, and where the joint bolt presents a reduced zone in correspondence with the teeth or grooves of the slotted window; the joint bolt is mounted on the female handle with means to prevent the turning of the bolt with respect to the female handle, and means to prevent the axial displacement of the bolt with respect to the female handle; the joint bolt includes the reduced zone centered and accompanied by two side walls which are housed in the respective orifice-housings of the female handle; the means to prevent the turning of the bolt with respect to the female handle are comprised of a spline and an orifice-housing conjugated with each other and centered/coaxial with the bolt itself; the coaxial spline defines two corners opposite each other, to fit without turning in the coaxial orifice-housing which for this purpose presents conjugated shape; the female handle defines a thick wall the thickness of which is at least equal to a height of the coaxial spline; and the means to prevent the axial displacement of the bolt with respect to the female handle include a stud bolt in a threaded orifice of the coaxial spline; said stud bolt also being centered/coaxial with the spline, with the orifice-housing and with the joint bolt itself.
