[0002] Surveying and mapping refers to the shape, size, spatial position and attributes of natural geographical elements or surface artificial facilities are determined, collected and drawn into a map. The drawing of surveying and mapping is divided into paper drawing and electronic drawing. When the paper drawing is stored, in order to avoid the occurrence of creases, the drawing is wound and stored in the storage cylinder by winding.

[0003] The drawing is wound and then directly inserted into the storage cylinder, which is the conventional use step of the storage cylinder. However, since the diameter of the storage cylinder is generally larger than the diameter of the wound drawing, and the inner groove of the conventional storage cylinder is generally cylindrical, the drawing is easily loose after being placed in the storage cylinder, resulting in that the drawing is attached to the inner surface of the four sides of the storage cylinder, increasing the frictional resistance between the drawing and the surface of the storage cylinder, and making it inconvenient to take out the drawing when the storage cylinder is inverted. Therefore, a portable storage cylinder for drawing is needed to facilitate the taking out of the drawing from the storage cylinder. SUMMARY

[0011] Preferably, the drying agent is located between the two pressing plates.

[0012] Preferably, the center rod is located below the fixed plate.

[0013] The beneficial effects of the present application are as follows:

[0014] 1) When the drawing body spreads outward, the shape of the placing groove is inverted circular table, so that the bottom end of the drawing body first contacts the bottom end of the placing groove, the drawing body cannot continue to spread outward, the center rod is located in the middle, which also hinders the drawing body from completely tilting to one side, avoids the complete adhesion of the drawing body and the inner wall of the placing groove, reduces the contact area of the drawing body and the placing groove, and facilitates the taking of the drawing body.

[0015] 2) The drying agent is placed in the inner groove and between the two pressing plates, the spring is used to press the pressing plate to clamp the drying agent, and the drying agent absorbs moisture to realize the drying of the placing groove. BRIEF DESCRIPTION OF DRAWINGS
