s3, locking, namely screwing the locking bolt (7) to enable the taper hole (5) to be abutted against the taper table (6), and locking the centrifugal table (3) and the diagonal rack (12) to avoid loosening of the centrifugal table (3) and the test tube in the centrifugal process;
s4, starting the centrifuge body (1) to enable the centrifuge table (3) to drive the test tube to rotate, so that centrifugal treatment is realized;
s5, unlocking, after the centrifugal table (3) stops rotating, rotating and loosening the locking bolt (7) until the centrifugal table (3) is jacked up by the second spring (15) to separate the conical table (6) from the inner wall of the conical hole (5), and at the moment, pushing the supporting ring (10) upwards by the elasticity of the first spring (11) to enable the limiting block (13) to be in abutting connection with teeth of the helical rack (12);
s6, sampling, after the centrifugal table (3) is jacked up, pressing a test tube to be taken out, pushing the supporting ring (10) to move downwards by the test tube, separating the limiting block (13) from the inclined rack (12), allowing the inclined rack (12) to be received into the mounting hole (14) under the action of gravity, slowly loosening the test tube, and resetting the first spring (11) to push the test tube out of the test tube hole (4) so as to facilitate taking out the test tube;
s7, resetting, and rotating the locking bolt (7) to enable the frustum (6) to be attached to the taper hole (5).
