The tool has holders (2, 3) movable along a pair of guides (1) that are spaced at a distance from each other. One of the holders carries a circular blade (2d) by rotating at a rotary handle (1c). The holder is moved by a threaded spindle (1d) that is connected with the rotary handle. Another holder is movable with a toothed roller (3d) by a lever (4). The lever is operated between the guides or distance- and holding elements (1a, 1b) and the latter holder. The lever is locked automatically in a clamping position or by operating a pin. |
