The body side surfaces meet each other curvilinearly and/or with an inclination, beginning from the lower surface and finishing on the upper bearing surface. The supporting blocks made on the side surfaces are restricted by their face surfaces rising from the lower surface of the body and by the side surfaces. A shaft designed for connection to the leverage is installed in the supporting blocks for turning. The shaft is positioned in the middle between the lower and upper body surfaces.
