<p>The accessory has slides (5, 6) assembled on rods (16) forming parallelograms to provide displacement that is identical and parallel to a work table by using a connection bolt (21), where the accessory is guided by the slides and set in a dimension of a base of a machining device. The parallelograms are connected by the bolt associating the rods in displacement of the rods to tighten a workpiece (22). Spacing of the rails allows release of a protection cover to ensure safety at beginning moment of machining.</p> |
