Problems solved by technology

[0002] Common stationery products with variable thickness and convenient storage of paper are only briefcases with folding structure on both sides, because this folding structure is also called organ bag. There is a large degree of stretching on the top, but the bottom cannot be stretched; the two side walls of each storage space of the organ bag gradually change from a V shape to a straight wall during the stretching process, which determines that it is not convenient to put paper, and The maximum storage thickness of each storage space is fixed. In addition, when loading heavy objects such as books, the two side walls are easily bulged out due to the extrusion of books; because of the above characteristics, people generally only use the organ bag to carry lighter items such as loose papers
