The most relevant difference with respect to conventional tools is that the upper jaw is hinged (6) and supported on a cam (8). By turning the cam, the opening of the jaws is adjusted without using the usual adjustment screw located in the handle. However, keeping said screw allows additional opening of the lower jaw. This opening can also be obtained by replacing the hole articulated with an actuating lever (3) with selectable notches (10 and 11). Dispensing with the adjustment screw allows a series of conical washers preloaded by a screw and nut (23) to be accommodated. If a pressure bar (2), initially positioned by a screw (15) and spring (16), moves and pushes the nut (23), exceeding the specified preload, the nut will move, facilitating closing. The tool can be very quickly adjusted, using a single hand, and provides a wider opening than usual.
