摘要

The mat has two hard rubber sections lying at right angles with one another, and triangular smoothed iron claws. Twelve holes are punched on the sections, where each hole is put together by a carriage bolt with a washer. A galvanized flat bar is fixed on lower side of each bolt by a screw-nut and a galvanized spring ring. Each bar has an end portion that is bent right-angled to about 20 millimeter and is grinded at 30 degrees.
