[0039] There are two extension plates 410 and two springs 412, which are symmetrical to each other along the vertical center axis of the displacement plate 46. A rectangular groove 56 is provided on the top of the displacement plate 46, and the rectangular groove 56 is located on the displacement track of the retaining ring 55.

The design of the switch 33 facilitates one-button starting of the motor 32, which is convenient for operation.

[0041] A specific application of the present embodiment is as follows: pouring the urine sample into the sample tube 31, and then placing the sample tube 31 on the top of the base 2 for placement. When the urine sample is being transported, if the sample tube 31 shakes during transportation, the urine sample may overflow, and the sample tubes 31 may collide with each other, affecting the storage and transportation of the urine sample. At this time, the motor 32 is started, and when the motor 32 rotates forward, it will drive the bidirectional screw rod 34 to rotate forward. The forward rotation of the bidirectional screw rod 34 will drive the two threaded sleeves 35 to move relative to the bidirectional screw rod 34, so that the two threaded sleeves 35 move to the same place at the same time, thereby driving the vertical rod 37 and the two clamping plates 38 to move relative to each other, and the sample tube 31 is located on the movement trajectory of the clamping plates 38. When the two clamping plates 38 move, they will clamp the two sides of the sample tube 31 and slightly fix it to reduce the shaking of the sample tube 31. When the vertical rod 37 moves, it will drive the squeezing rod 315 and the squeezing block 316 to move. The triangular block 312 is located at the squeezing On the movement trajectory of the pressing block 316, when the squeezing block 316 moves, it will squeeze the triangular block 312. The squeezing block 316 and the triangular block 312 are both provided with corresponding inclined surfaces. Through the influence of the inclined surfaces, when the squeezing block 316 squeezes the triangular block 312, the triangular block 312 will drive the short plate 311 to rotate downward, and the downward rotation of the short plate 311 will drive the turntable 310 to rotate downward, and the downward rotation of the turntable 310 will drive the support rod 313 and the support plate 314 to rotate downward. The sample tube 31 is located on the movement trajectory of the support plate 314. When the support plate 314 rotates downward, it will get close to the inner wall of the sample tube 31 to support the sample tube 31 and reduce the shaking and displacement of the sample tube 31. Through the clamping effect of the clamping plate 38, the sample tube 31 reduces shaking and displacement during transportation, thereby reducing the risk of urine sample overflow. By stabilizing the sample tube 31, collisions between the sample tubes 31 can be effectively prevented, the possibility of cross contamination can be reduced, and the purity of the sample can be ensured.

[0042] When the cover 42 is opened, it is supported by two telescopic rods 43. After the sample tube 31 is placed in the retention box 1, when the urine sample needs to be sealed, the cover 42 is manually rotated toward the side close to the motor 32, and the cover 42 is closed, so that the cover 42 rotates along the rotating rod 41. The rotation of the cover 42 drives the trigger rod 44 to move. The extension plate 410 is located on the movement track of the trigger rod 44. When the trigger rod 44 moves, it squeezes the extension plate 410, and the extension plate 410 is moved. The extension plate 410 is squeezed downward to move downward, and the downward movement of the extension plate 410 drives the connecting rod 48 and the sealing plug 49 to move downward. The sample tube 31 is located on the movement track of the sealing plug 49. When the sealing plug 49 moves downward, the tube openings of several sample tubes 31 are blocked, so that after the retention box 1 is covered with the cover plate 42, the sample tubes 31 are sealed at the same time. The automatic sealing mechanism enables multiple sample tubes 31 to be sealed at one time when the cover plate 42 is covered. This process does not require additional operating steps, reduces the time of manual operation, and improves the work efficiency of the laboratory. By sealing the sample tube 31, external contaminants are prevented from entering the sample, thereby ensuring the integrity and effectiveness of the urine sample.

[0043] When the sealing plug 49 blocks the mouth of the sample tube 31, it may be stained with urine samples. After the sealing plug 49 is stained with urine samples, when the next batch of urine samples of others is sealed, it may affect the samples of others, resulting in impure samples. Therefore, the sealing plug 49 needs to be replaced from time to time. The fixing plate 51 is fixedly connected to the top of the displacement plate 46, and a long rod 52 is simultaneously passed through the sides of the fixing plate 51 and the connecting rod 48, so as to fix the connecting rod 48 and the sealing plug 49 in the fixed position. On the side of the fixed plate 51, the long rod 52 penetrates the side of the fixed plate 51 and the connecting rod 48 at the same time and is slidably connected. One end of the long rod 52 is fixed by the circular plate 53 and cannot be taken out from the side of the fixed plate 51 and the connecting rod 48. A clamping groove 54 is provided at the end of the long rod 52 away from the circular plate 53. A small connecting rod is provided on the inner wall of the clamping groove 54. A clamping ring 55 is mounted on the connecting rod. When the clamping ring 55 is mounted on the connecting rod, the clamping ring 55 will be in a downward hanging state, and this end of the long rod 52 will be secured by the clamping ring. The long rod 52 can be removed from the side of the fixed plate 51 and the connecting rod 48 due to the limitation of the long rod 55. When the sealing plug 49 needs to be replaced, the retaining ring 55 is manually moved upward to a position flush with the long rod 52. The retaining ring 55 will no longer hang on the small connecting rod, and the long rod 52 can be taken out from the side of the fixed plate 51 and the connecting rod 48. At this time, the connecting rod 48 is no longer connected to the long rod 52, and the connecting rod 48 will slide out from the inner wall of the groove 47, driving the sealing plug 49 to be removed from the displacement plate 46, so as to replace the sealing plug 49. The sliding connection design of the long rod 52 makes the process of replacing the sealing plug 49 simpler and more efficient. The operator only needs to manually move the retaining ring 55 to quickly release the long rod 52, and then easily remove the connecting rod 48 and the sealing plug 49. This simplified replacement process improves work efficiency, reduces operation time, and reduces the risks caused by improper operation. The design of regularly replacing the sealing plug 49 reduces repeated testing due to sample contamination, thereby reducing the overall inspection cost and improving the efficiency of resource utilization.
