The side of the handle 52 is fixedly connected with an anti-slip sleeve 53, and personnel can control the handle 52 with the help of the anti-slip sleeve 53. It can be avoided as much as possible that the personnel's hands slip when controlling the handle 52, thereby achieving the effect of conveniently controlling the handle 52.

[0039] Detailed description of the method of use: In the present invention, when a person needs to take out a test tube containing a medical specimen in the storage box 1, the servo motor 305 is first started to drive the gear 306 to rotate, the gear 306 drives the tooth block 303, the tooth block 303 drives the connecting ring 301 to rotate, the connecting ring 301 drives the test tube inside the fixed hole 302 to rotate to just below the circular hole 310, when the test tube rotates to just below the circular hole 310 on the partition 309, the electric push rod 311 is started again to drive the connecting plate 312, the connecting plate 312 drives the baffle 313 to separate from the circular hole 310, when the circular hole 310 is completely opened, the person pulls the pull ring 326 to drive the fixing rod 317, the fixing rod 317 drives the motor 319, the motor 319 drives the turntable 320 and the limit plate 323, so that The test tube is placed between several limiting plates 323, and then the motor 319 is started to drive the turntable 320 to rotate. The turntable 320 drives the boss 322 with the help of the connecting hole 321, so that the boss 322 drives the limiting plate 323 to squeeze the test tube in the limiting position of the guide rod 325. When the test tube is clamped stably, the pull ring 326 is pulled to drive the fixed column, and the fixed column drives the test tube to move in the direction close to the box cover 6. After the limiting plate 323 drives the test tube to pass through the circular hole 310, the electric push rod 311 is started to drive the connecting plate 312, and the connecting plate 312 drives the baffle 313 to block the circular hole 310. Then the personnel can open the box cover 6. When the box cover 6 is opened, the motor 319 is started again to drive the turntable 320 to rotate in the opposite direction, so that the limiting plate 323 is separated from the test tube. The test tube removal operation can be completed at this time. When a test tube containing a medical specimen needs to be placed in the storage box 1, the box cover 6 is first opened, and then the motor 319 is started to drive the limit plate 323 to clamp the test tube, and then the box cover 6 is closed, and then the electric push rod 311 is started to open the baffle 313, and then the pull ring 326 is pulled to drive the fixing rod 317, and the fixing rod 317 drives the test tube to enter the fixing hole 302. When the test tube enters the fixing hole 302, the motor 319 is started again to drive the turntable 320 to rotate in the opposite direction, so that the turntable 320 drives the limit plate 323 to separate from the test tube, and then the fixing rod 317 is pulled to drive the limit plate 323 to pass through the circular hole 310. When the limit plate 323 passes through the circular hole 310, the electric push rod 311 is started again to drive the baffle 313 and the sealing The circle 316 blocks the circular hole 310, so that the test tube can be placed. Each time a person opens and closes the box cover 6, the exhaust pump inside the exhaust pipe 2 can be started to extract the air inside the storage box 1, so that the inside of the storage box 1 can be kept in a vacuum state. Two effects are achieved by setting the adjustment device 3: first, when a person opens the box cover 6 to take or place one or more test tubes, the outside air cannot enter the space formed by the storage box 1 and the partition 309, so that the temperature of the space can be kept constant, which is very important for specimens that need to be stored in a specific low-temperature environment, and helps to ensure their stability and preservation effect; second, microorganisms, dust and other pollutants in the outside air cannot enter the storage box 1, reducing the risk of medical sample contamination.

[0040] When the locking cam 311 is in the locked state, the locking cam 315 will be in the locked state, so the locking cam 315 will be in the locked state.

[0041] In the present invention, when it is necessary to fit test tubes of different sizes into the fixing hole 302, the test tube is first moved into the fixing hole 302. At this time, the spring 43 can control the top block 42 to squeeze the test tube, thereby enabling the test tube to be fixed firmly. The anti-slip pattern 44 can increase the friction force of the top block 42 close to the side of the test tube, thereby improving the limiting effect of the top block 42 on the test tube. By setting the limiting device 4, personnel can conveniently fix test tubes of different sizes in the fixing hole 302, thereby improving the application scope of the medical specimen preservation and transportation device.

[0042] In the present invention, when the handle 52 is needed to carry and transport the medical specimen storage and transport device, the adjusting ring 56 is first rotated to move along the arc surface of the slide rod 55 to separate the adjusting ring 56 from the fixing seat 51, and then the personnel can rotate the handle 52 to a suitable angle to transport the storage box 1. When the storage box 1 is transported to a suitable position, the handle 52 is rotated to a suitable position, and then the adjusting ring 56 is rotated to abut against the fixing seat 51, so that the handle 52 can be fixed, wherein the rubber pad 57 can increase the friction force of the adjusting ring 56 close to the fixing seat 51. , achieving the effect of making the adjustment ring 56 firmly contact with the fixing seat 51 with the help of the rubber pad 57, so that the handle 52 can be fixed more firmly. In addition, the personnel can control the handle 52 with the help of the anti-slip sleeve 53, which can avoid the personnel's hands slipping when controlling the handle 52, and achieve the effect of conveniently controlling the handle 52. By setting the auxiliary device 5, the personnel can conveniently adjust the handle 52 to transport the medical specimen preservation and transportation device, thereby improving its portability, and after the use of the handle 52, the handle 52 can be conveniently stored and fixed.
