Component units can be introduced a pin, which is articulated by its head to the end of a small arm, articulated in turn to a mid point of a curvilinear lever, which is mounted pivoting on the free end of a support-plate, welded between each two tubes and extending perpendicularly from there towards the interior of the cavity of the piece.
