Problems solved by technology

[0004] However, after the drawings are put into the cylinder, due to the fact that they are not affected by external forces, the drawings will automatically stretch and stick to the inner wall of the cylinder. Take it out. At this time, the staff can only turn the cylinder over and hit it against the table or other areas to make the drawing fall out. This method will not only damage the drawing cylinder, but may also damage the drawing; at the same time, when the height of the drawing is less than When the height of the cylinder is high, it is more difficult to take it out after being put into the cylinder. Forcible pulling may also cause the drawing to be damaged, causing certain economic losses to the user
