When the plurality of plugging plates 210 enclose a closed chamber, the refrigeration sheet 470 begins to work, ensuring that the chamber in which the test tube is placed is a low temperature environment, and further ensuring that the sample in the test tube does not infect other substances.
In a further embodiment, a first torsion spring 480 is connected between the transmission member 220 and the placement stage 140; a second torsion spring 490 is provided between the transmission member 220 and the blocking plate 210. Specifically, under the action of the first torsion spring 480 and the second torsion spring 490, the transmission member 220 is in inclined rotation, the placing table 140 is stably located on the upper portion of the guide rod 130, when the test tube is placed on the placing table 140, the gravity of the test tube drives the placing table 140 to slide along the guide rod 130, meanwhile, the first torsion spring 480 and the second torsion spring 490 store force, and when the test tube is separated from the placing table 140, the first torsion spring 480 and the second torsion spring 490 start to release force, so that the placing table 140 moves from bottom to top along the guide rod 130, and the placing table 140 returns to the initial position, so that the test tube can be placed next time. When the test tube needs to be taken out from the cavity enclosed by the plugging plate 210, a worker manually dials the plugging plate 210 outwards, so that the plugging plate 210 is converted from the first state to the second state, in the process, the rotation of the plugging plate 210 drives the driving gear 410 to reversely rotate, the second rack 430 slides along the radial direction of the mounting plate 310 through the gear transmission of the first rack 420, the driving rod 440 and the two ends of the driving rod 440, and at this time, the plurality of shearing fork mechanisms expand outwards and do not have any resistance, and at this time, the friction plates 443 on the first driving section 441 and the friction plates 443 on the second driving section 442 ensure that the plurality of shearing fork mechanisms do not contact the test tube through static friction transmission, and then the test tube is taken out from the placing table 140.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
