[0042] The two ends of the torsion spring 212 are respectively connected to the mounting seat 213 and the receiving slot 201, and a positioning hole 214 is formed at one end of the mounting seat 213;

[0043] The outer wall of the insertion rod 208 is sleeved with a limit ring 209, and the two ends of the spring 205 are respectively connected to the limit ring 209 and the receiving groove 201. The elasticity of the spring 205 is greater than the elasticity of the torsion spring 212. A pull handle 207 is provided at the upper end of the insertion rod 208;

[0044] A symmetrically distributed telescopic slot 203 is provided inside one end of the sampling box 100, a telescopic rod 202 is slidably inserted inside the telescopic slot 203, a pull handle 204 is provided at one end of the telescopic rod 202, an annular retaining ring is provided at the opening of the telescopic slot 203, a stopper is provided at one end of the telescopic rod 202, and the outer diameter of the stopper is greater than the inner diameter of the stopper ring;

[0045] Performing use of the rolling structure 200;

[0046] Instruments and devices for epidemiological surveys are stored in the storage slot 101, and the collected samples are placed in the sampling box 100. When carrying the sampling box 100, the handle 207 is grasped and the springs 205 are squeezed away from each other. When the insertion rod 208 moves out of the positioning hole 214, the mounting seat 213 is bounced outward by the torsional elasticity of the torsion spring 212, so that the roller 211 flips in direction, the handle 204 is grasped, and the telescopic rod 202 is pulled.

[0053] Using the storage structure 300;

[0054] When the sampling box 100 is in use, the air pump 301 conveys gas into the airbag 303 through the air pipe 302. After the airbag 303 is inflated, it is rectangular and located at the upper end of the sampling box 100. The internal space at the upper end of the sampling box 100 is expanded, and the storage volume is increased. After the sampling box 100 is used, the roller 211 is relatively pulled up so that the roller 211 is located inside the storage groove 201, and is inserted into the corresponding positioning hole 214 through the insertion rod 208. The elastic support of the spring 205 makes the roller 211 stable, and the roller 211 is stored in the storage groove 201, and the telescopic rod 202 is stored in the telescopic groove 203. After the sampling box 100 is used, the exhaust valve is opened, and the gas inside the airbag 303 is output through the exhaust pipe 302. The airbag 303 is deflated, and the overall volume of the sampling box 100 is reduced, and it occupies less space during storage, which is convenient for storage.
