[0037] In the embodiment, the technical content disclosed in the embodiment is further improved on the basis of the above-mentioned embodiment one. The existing plant disease and pest leaf quarantine specimen sampling box cannot automatically adjust the holding environment during use, so that the leaf preservation effect is poor, thereby affecting the subsequent detection effect. In order to further solve this technical problem, the embodiment discloses the following technical content, as shown in Figures 3-4 and Figures 9-11 The upper and lower ends of the center column 4 are rotatably installed with the containing barrels 12, the open ends of the containing barrels 12 are threadedly connected with the fixed covers 13, the inner sides of the two containing barrels 12 are respectively filled with moisture absorbent and water storage cotton, the movable supporting plate 5 and the containing barrels 12 are connected with the transmission assembly for driving the containing barrels 12 to rotate, the inner side of the partition plate 3 is provided with two cavities, and the inner side of the cavity is provided with the pressure regulating assembly for regulating the air pressure in the storage box 1.

[0038] The box assembly is distributed at equal angles outside the containing cylinder 12, and the containing cylinder 12 is provided with a guide groove 1201 penetrating the cylinder body, and the moisture absorbent inside the upper containing cylinder 12 absorbs the water vapor in the space above the partition plate 3 through the guide groove 1201, and the water storage cotton inside the lower containing cylinder 12 moisturizes the air in the space below the partition plate 3 through the guide groove 1201.

The guide groove 1201 is arranged in a spiral structure, and when the movable supporting plate 5 drives the fixed cylinder 14 to elastically lift and adjust, the rotating column 15 slides along the guide groove 1201 to drive the containing cylinder 12 to rotate. The diameter of the moisture absorbent and the water storage cotton inside the containing cylinder 12 is greater than the width of the guide groove 1201, and the lower end of the upper fixed cover 13 is fixedly installed with a stirring rod 16, and the stirring rod 16 stirs the moisture absorbent when the upper containing cylinder 12 rotates, and the lower containing cylinder 12 rotates to accelerate the evaporation of water in the water storage cotton. The center position of the center column 4 is a spherical structure, and the middle part of the center column 4 is connected with the partition plate 3 in a ball shape, and the outer diameter of the movable supporting plate 5 is smaller than the inner diameter of the storage box 1, and the partition plate 3 and the center column 4 rotate and adjust during the shaking of the storage box 1. The pressure regulating assembly includes a piston sheet 17 which is interference slidingly installed in the internal cavity of the partition plate 3, and a return spring 18 is fixedly connected between the piston sheet 17 and the inner wall of the cavity, and a traction rope 19 is fixedly connected between the piston sheet 17 and the center column 4. The piston sheet 17 is elastically slid in the cavity by the traction rope 19 during the rotation of the center column 4. The partition plate 3 is further fixedly installed with an air pipe 20 which communicates the internal space of the storage box 1 and the cavity structure.

[0039] The upper containing cylinder 12 can absorb moisture and dry the gas in the space above the storage box 1 through the moisture absorbent inside it, and the lower containing cylinder 12 can humidify the air through the water storage cotton inside it, so that the storage box 1 has different storage environments. When the storage box 1 shakes, the center column 4 rotates, so that the center column 4 can pull the piston sheet 17 in the cavity of the partition plate 3 to elastically interference slide, thereby adjusting the flow of gas in the cavity and the storage box 1, so as to automatically regulate the air pressure in the internal space of the storage box 1. When the air pressure inside the storage box 1 rises, the elastic breathable film 10 will deform to a certain extent to clamp the blade, and with the change of the air pressure outside the elastic breathable film 10, the circulation and exchange of the air inside and outside the protection box 7 can be accelerated, thereby promoting the regulation of the environment inside the protection box 7, and further improving the preservation effect of the blade specimen. The elastic breathable film 10 can be a polypropylene (PP) microfiltration membrane.

[0040] As Figure 9As shown, as the movable supporting plate 5 slides outside the center column 4, the movable supporting plate 5 can drive the fixed cylinder 14 to synchronously ascend and descend, so that the rotating column 15 on the inner wall of the fixed cylinder 14 slides along the spiral-shaped guide groove 1201, thereby driving the containing cylinder 12 to synchronously rotate and adjust; at this time, the upper containing cylinder 12 can cooperate with the stirring rod 16 to stir the moisture absorbent, thereby promoting the moisture absorption effect, and the lower containing cylinder 12 can promote the volatilization of water in the water storage cotton block inside the containing cylinder 12 through rotation, thereby realizing effective moisturizing of air and achieving automatic regulation and control of the environment.
