[0037] The working principle of the technical scheme of the utility model is as follows:

[0038] When the worker installs the fixed assembly, first, the rotor 2 is aligned with the rotating shaft inside the centrifuge body 1 and inserted, then the clamping piece 10 is aligned with the test tube slot 11 and inserted, so that the clamping piece 10 is inserted into the inside of the test tube slot 11, the threaded piece 4 and the connecting piece 6 are inserted into the inside of the mounting piece 3, then the worker rotates the threaded piece 4, so that the threaded piece 4 is threadedly connected in the inside of the mounting piece 3 and the rotating shaft of the centrifuge body 1, until the threaded piece 4 is simultaneously threadedly connected in the inside of the mounting piece 3 and the threaded piece 4, so that the rotor 2 is fixedly connected with the rotating shaft of the centrifuge body 1 through the mounting piece 3 and the threaded piece 4, then the worker continues to rotate the threaded piece 4, which will squeeze the air bag 5 and the connecting piece 6 that are blocked by the mounting piece 3 and cannot continue to drop, so that the gas in the air bag 5 is transmitted to the inside of the telescopic air bag 8 through the soft air pipe 7, and then the telescopic air bag 8 is expanded and elongated to push the clamping piece 10 to move, the movement of the clamping piece 10 will slide into the inside of the limiting guide groove 12 through the position in contact with the limiting guide groove 12, at this time the worker can see that the clamping piece 10 moves the fixed assembly installation is completed, and the clamping piece 10 is guided and limited by the limiting guide groove 12, so the worker can stop rotating the threaded piece 4, and continue to rotate the test tube slot 11 after the test tube is inserted into the inside of the test tube slot 11, until the telescopic rod 9 continues to elongate to push the clamping piece 10 to clamp and fix the test tube, so as to achieve the effect of clamping and fixing test tubes of different sizes, when the clamping piece 10 clamps and fixes the test tube, the worker cannot continue to rotate the threaded piece 4, the sealing cover can be threadedly connected to the outer wall of the mounting piece 3 to seal and fix the top of the rotor 2, and after the cover plate of the centrifuge body 1 is closed, the centrifuge is controlled to centrifuge the test tube;

[0039] It should be noted that after the centrifuge is completed, the worker can open the cover plate of the centrifuge body 1 and remove the sealing cover from the mounting piece 3, then the worker can reversely rotate the threaded piece 4, so that the threaded piece 4 gradually separates from the mounting piece 3 and the rotating shaft of the centrifuge body 1, so that the threaded piece 4 gradually stops squeezing the air bag 5, because the test tube in the test tube slot 11 of the rotor 2 is inclined, the test tube will slide and incline in the inside of the test tube slot 11 and squeeze the clamping piece 10 to slide back along the inside of the limiting guide groove 12, so that the test tube slot 11 squeezes the telescopic air bag 8 and the telescopic air bag 8 resets, so that the gas in the telescopic air bag 8 is discharged back to the inside of the air bag 5 through the soft air pipe 7, so that the air bag 5 is inflated and reset, waiting for the next work, then the worker can take out the test tube from the test tube slot 11 of the rotor 2, if the worker needs to clean and disinfect the rotor 2 and the fixed assembly, the worker can continue to reverse the threaded piece 4, until the threaded piece 4 is completely separated from the mounting piece 3 and the rotating shaft of the centrifuge body 1, at this time the worker can take out the fixed assembly from the test tube slot 11 of the centrifuge body 1 through the threaded piece 4, and move to a position convenient for the worker to disassemble the fixed assembly and the rotor 2, so as to facilitate the worker to clean and disinfect the fixed assembly and the rotor 2.
