1. A crushing or cutting device comprising: a body, crushing/cutting jaws making rotation and attached to the body by one or several shafts, a first power unit to move said jaws against each other, whereby at least one said shaft of said jaw is fitted with bearings to rotate in regard both to said body and whereby said jaw and said bearings are eccentric among themselves, and the device has a second power unit in order to rotate at least one said shaft, characterized in that said second power unit is fitted to press said jaws against each other in multiplying the motive force of the second power unit between an eccentricity distance of the bearings and by a torsion arm longer than said eccentricity distance connected to the shaft, in a situation, where at least one said shaft is rotated 180° at the most, and when the first power unit is hydraulically locked or in a position pressing the jaws against each other.
