After the power is connected, the operation of the dual-axis motor (201a) can be controlled through the operation panel (102); S3: Cooperating with the operation panel (102), the speed of the output of the dual-axis motor (201a) can be controlled to cooperate with the subsequent centrifugal degassing operation; S4: placing materials required for the APTT liquid inside the test tubes, placing multiple test tubes inside five placement racks (2032), starting the dual-axis motor (201a), and causing the turntable (201b) to rotate; S5: The working chamber (202a) is caused to vibrate reciprocatingly up and down by hingedly connecting the rotating disk (201b) and the connecting block (201c), and by hingedly connecting the connecting block (201c) and the connecting plate (201d); S6: At the same time, the right end output rod of the dual-axis motor (201a) cooperates with the transmission action of the bevel gear (202b) to rotate the telescopic rod (202c), and cooperates with the action of the spring (2033) to enable the placement rack (2032) to be quickly extended during the centrifugal degassing operation.
