Therefore, pressure difference still exists between the upper cavity and the lower cavity, and calligraphy works can be laid above the elastic dividing surface 2 in a flat state all the time in the display groove even if a fixing mechanism is not arranged. Compared with the prior art of utilizing solid fixation, the pneumatic fixation method can effectively avoid the situation that the paper is damaged when being taken down due to the fact that the paper is adhered to the fixing device because molecules among solids are diffused.
