The size of the lower edge of the trapezoidal steel plate is determined to be 1.2 meters, the height of the trapezoidal steel plate is determined to be 0.4 meter, and the size of the upper edge of the trapezoidal steel plate is determined to be 0.8 meter by measuring the width and the height of the widest material surface on site. For convenience of calculation, the length of the connecting rod is 36 cm, so that the material cutting length of the material cutter is 36 cm. The trapezoidal steel plates are required to be flat, the connecting rods are perpendicular to the trapezoidal steel plates for welding, the two trapezoidal steel plates are parallel, and the inner size of the space is 36 cm.
