The working element is made up by sharpened teeth arranged in a single row and connected in the upper part thereof by a joint plate on which a vertical leg is fixed with shifting from center thereof. One of the teeth is made as a straight stopper and connected by the end of the plate, which is short from the leg, other teeth are made as spiral-like ones and arranged along the internal side of the plate on the same distance between each other. |
