A screw support of increased loading ability is made in the form of a cylindrical rod, which from below has conical form, and to its external diameter a screw support is rigidly connected by inside diameter, it is in the form of a screw, which from below has conical form. The cylindrical rod is made in the form of a hollow pipe, on lower butt end of which incisions are made evenly in the circle in radial direction to its axis, in addition to this in the internal opening of hollow pipe a screw is installed, which by internal diameter is rigidly connected with a shaft with possibility of circular and axial displacement, which from below has conical shape as screw itself, and from the upper end to the hollow pipe a large flywheel is perpendicularly rigidly fastened, along external diameter of which two driving fingers are rigidly fixed, which axes are perpendicular to its plane and are parallel between them. |
