[0026] Embodiment Two

[0027] The main differences from Example 1 are:

In addition, the synchronization assembly 36 and the reversing assembly 37 are provided inside the sample testing box 1, so that the rotation of the driving column 322 at the bottom of the sample testing box 1 can be converted into the rotation of the middle rotating rod 319, so that the upper component can be driven by the movement. Then, the sealing block 31 can rotate after the test tube box 312 moves to the appropriate position, which can effectively ensure that the test tube port is sealed.

[0029] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] During operation, first place the serum to be tested inside the test tube box 312, place a suitable lid in the placement groove 315 inside the sealing block 31, then pull out the clamping rod 314 outward, slide the operation block 313 downward, and rotate the sealing block 31 to seal the sample detection box 1.

After the dropper module 311 moves upward, move the test tube box 312 to the right again. At this time, it will drive the drive block 320 to move downward. The movement of the drive block 320 will drive the drive column 322 to rotate 90 degrees inside the sample detection box 1 through the drive rod 321. The rotation of the drive column 322 will drive the rotation rod 319 to rotate through the synchronization component 36 and the commutation component 37. Furthermore, the sealing block 31 rotates above the test tube box 312, the test tube contacts the elastic rod 318, and the downward movement of the sealing block 31 will cause the elastic rod 318 to move to both sides, and the lid moves to one end of the test tube for preliminary sealing. When taking out the test tube after stopping the reagent dropping, the lid can be pressed or rotated to stably fix the lid and the test tube, and then the next experiment can be carried out.
