A second rack 406 is slidably installed in the second mounting groove 5, pressing the connecting frame 403 downward to drive the sealing plate 401 to move downward. When the sealing plate 401 moves downward, it will push the first rack 404 to move downward. At this time, the first rack 404 will drive the gear 405 to rotate. When the gear 405 rotates, it will drive the second rack 406 to move upward, and drive the connecting plate 407 and the closing block 408 to move upward along the direction of the second mounting groove 5. When the closing block 408 moves upward, it will move out of the connecting frame 305.

[0032] In this embodiment, refer to Figure 2 and Figure 5 As shown, the first rack 404 is meshed with the gear 405, and the gear 405 is meshed with the second rack 406. A connecting plate 407 is fixedly installed at the bottom of the side wall of the second rack 406, and a closing block 408 is fixedly installed at the bottom of the connecting plate 407. The closing block 408 is slidably installed inside the connecting frame 305.

[0033] Working principle: when in use, first screw the closing bolt 409 to inject the liquid from the hole formed by the closing bolt 409 penetrating the sealing plate 401, and then tighten the closing bolt 409 after injection to close the device. At this time, press the connecting frame 403 downward to drive the sealing plate 401 to move downward. When the sealing plate 401 moves downward, it will push the first rack 404 to move downward. At this time, the first rack 404 will drive the gear 405 to rotate. When the gear 405 rotates, it will drive the second rack 406 to move upward, and drive the connecting plate 407 and the closing block 408 to move upward along the direction of the second mounting groove 5. When the closing block 408 moves upward, it will move out of the connecting frame 305, thereby opening the connecting frame 305;

[0034] Before performing the above steps, place the collection test tube at the bottom of the liquid guide tube 306 to collect liquid. When the collection test tube is almost full, pull the second connection block 3011 to drive the first telescopic rod 309 and the first spring 3010 to extend and retract, so that the second connection block 3011 is in contact with the rubber pad 3012 and the second connection block 3011 is rotated to drive the rotating column 307 and the fan-shaped plate 308 to rotate synchronously, so as to close the liquid guide tube 306 above the test tube that is almost full.

[0035] When the device needs to be cleaned after use, the clamping block 3015 is pulled to compress the second telescopic rod 3013 and the second spring 3014 and receive them in the receiving groove 8, so that the first connecting block 301 and the liquid guiding tube 306 can be quickly disassembled.
