after the sample container 1 containing the blood sample is taken, the worker at S01 throws the sample container into the cone or into the sample arranging device 6, and sends the sample container onto the guide plate 7 through the sample arranging device 6.

S02 the sample container 1 falls onto the first rotating shaft 222 and the second rotating shaft 223 by its own weight, and at this time, the gap between the first rotating shaft 222 and the second rotating shaft 223 is smaller than the diameter of the container body 11, and the sample container 1 is supported by the first rotating shaft 222 and the second rotating shaft 223 without falling.

S03 when the specimen container 1 reaches the upper side of the first and second rotary shafts 222 and 223 to be supported, the specimen container 1 is detected by the first sensor 251, and the first sensor 251 emits a first sensing signal.

S04 the first controller receives the first sensing signal from the first sensor 251 and controls the first driving member 224 to drive the second rotating shaft 223 to move a first distance away from the first rotating shaft 222 along the first direction, so that the gap between the second rotating shaft 223 and the first rotating shaft 222 is larger than the diameter of the container 11 and smaller than the diameter of the container lid 12, and at this time, the container 11 falls through the gap between the first rotating shaft and the second rotating shaft under the action of its own gravity, and the container lid 12 is still limited by the first rotating shaft and the second rotating shaft, so that the specimen container 1 is in a vertical state.

S11, when the sample container 1 reaches the pressure relief pipe 8, the first receiving sensor 44 senses that the first receiving sensor 44 sends a first receiving signal.

S12 when the second controller receives the first receiving signal, the second controller controls the third driving element to drive the valve 421 to close the outlet of the receiving tube, and controls the second regulating valve on the second air supply hose to open, so that the compressed air enters the receiving tube through the second air supply hose (the pressure of the compressed air flowing through the second air supply hose is lower than that of the compressed air flowing through the first air supply hose), and the compressed air passing through the second air supply hose recoils the sample container in the receiving tube, thereby reducing the moving speed of the sample container 1, and discharging the excessive compressed air through the pressure relief tube.
