The gripper of the sample analyzer passes through the two trays 2 from one side of the frame 1 and extends into the transfer area to take out the test tube rack 5. This utility model can automatically pick up and deliver the test tube rack 5 of the sample, with a higher degree of automation.

[0025] like Figure 1-8As shown, the tray 2 includes an annular plate 21 fixed on the frame 1, and multiple partition blocks 22 radially arranged on the annular plate 21 with the axis of the annular plate 21 as the center. Multiple tube rack slots 23 are formed between adjacent partition blocks 22 and the annular plate 21. The multiple tube rack slots 23 are distributed radially outward with the axis of the annular plate 21 as the center. The two ends of the tube rack slots 23 are connected to the inner arc surface and the outer arc surface of the annular plate 21. In this embodiment, the multiple tube rack slots 23 formed between adjacent partition blocks 22 and the annular plate 21 enable each tray 2 to accommodate multiple test tube racks 5, and the test tube racks 5 are snapped into place by the tube rack slots 23.

[0026] like Figure 1-8 As shown, the frame 1 includes two main boards 11 arranged vertically opposite each other, multiple support columns 12 for connecting the two main boards 11, and multiple connecting rods 13 for connecting the two main boards 11. One side of the support column 12 is provided with a slot facing the annular plate 21, and the outer arc surface of the annular plate 21 engages with the slot. The bottom of the partition block 22 is vertically provided with multiple buckles 23, and the annular plate 21 is provided with a hole facing the buckle 23. The partition block 22 is detachably connected to the annular plate 21 by engaging the buckle 23 with the hole.
