Among them, the conveying directions of the first conveyor line 1 and the second conveyor line 2 are the same, the conveying directions of the second conveyor line 2 and the third conveyor line 3 are opposite, and the third conveyor line 3 is arranged close to the first conveyor line 1. By arranging the first conveyor line 1, the second conveyor line 2, and the third conveyor line 3 at intervals, and cooperating with the first displacement mechanism 4 and the second displacement mechanism 5, the blood collection tubes on the first conveyor line 1 can be conveyed on the first conveyor line 1, the second conveyor line 2, or the third conveyor line 3 to be conveyed to the corresponding detection unit, so as to accelerate the processing speed of blood collection tube samples, greatly shorten the detection cycle, and accelerate the report issuing speed.
