The fixing component can fix test tube bodies 27 of different sizes to prevent the test tube body 27 above from shaking when the support frame 13 moves, causing the nucleic acid reagent inside the test tube body 27 to spill out. By taking out the support plate 10 and the support frame 13 from the inside of the cabinet body 1, it is convenient to clean the inside of the cabinet body 1.

[0027] Refer to Figure 2 , Figure 4 and Figure 5 , the fixing component includes a convex block 16, the convex block 16 is engaged with the convex groove 15, a test tube slot 17 is opened at the top right end of the convex block 16, fixing blocks 18 are fixedly connected to both the front and rear ends of the top of the convex block 16 inside the test tube slot 17, springs 19 are fixedly connected to the opposite ends of the two fixing blocks 18, clamping plates 20 are fixedly connected to the opposite ends of the springs 19, pulling blocks 26 are fixedly connected to the tops of the fixing blocks 18, a label box 21 is fixedly connected to the top left end of the convex block 16, a through slot 22 is opened at the front end of the label box 21, a slot 23 is opened at the top of the label box 21, a label one 24 is arranged inside the slot 23, an L-shaped block 25 is fixedly connected to the top of the label one 24, the bottom end of the test tube body 27 is in contact with the bottom end of the test tube slot 17, the opposite sides of the clamping plates 20 are in contact with the outer side of the test tube body 27, the through slot 22 communicates with the slot 23, the label one 24 is slidably connected to the slot 23, and the front end inside the L-shaped block 25 is in contact with the front end of the label box 21.

[0028] Place the bottom of the test tube body 27 in contact with the bottom of the test tube slot 17, and the springs 19 drive the adjacent two clamping plates 20 to be in contact with the outer side of the test tube body 27, thereby clamping the test tube body 27 in the middle of the test tube slot 17. The test tube slot 17 and the two clamping plates 20 make the fixation of the test tube body 27 relatively stable and applicable to test tube bodies 27 of different sizes.
