Pliers connected to a handle - It can be useful if the guide jaws, the handles of which are counter-slits like scissors on the jaws of the pliers slightly at an angle from the move the other, with both jaws pivoting the rear end against the gripping side of the jaws stored on the associated handles ken run towards each other and if the location of the and in each case the one handle one on a slot guide slots is chosen so that the Zangenbak- and a guide pin engaging there form an angle between them in the open position

and the gripping sides can approach each other when closing one of the pliers jaws opposite the actual handle, projection 10 arranged. The guide pin 9 on each of these gripping sides is only just before they meet. With joint S opposite side of the common such an arrangement of the jaws and ib.- 5 joint 2 of the two handles with distance other guides for the closing movement performs the orderly. When swiveling the rter handles 3, the outer end of the gripping side of the movable pliers because, accordingly, these guide pins 9 bake on a slightly larger path than the inner other towards or away from each other. In the latter case, the end of the gripping sides, with the deviation of the spread the rear ends 7 of the pliers covered path, however, much smaller than in the case of the jaw 4, while the jaw joints S, which is a scissor movement. In the case of such a device, they also move away from each other, but the front, reduced shear effects already form the ends of the pliers jaws 4 spreading apart, comparatively smooth cut surfaces.
