The collecting box 2 is fixed by the fixing blocks 17 when they are extended, and after the collecting box 2 retracts into the shell 4, the pull rod 14 can be loosened to allow the spring 15 to push the fixing blocks 17 into the fixing holes 11 to fix the collecting box 2.

[0034] One end of the two springs 15 is fixedly connected to one end of the fixing block 17 close to the pull rod 14, and the other end of the two springs 15 is fixedly connected to the top wall of the mounting groove 16. The elastic force of the springs 15 is used to push the fixing block 17 into the fixing hole 11 to fix the collection box 2.

[0035] A slide groove 20 is provided at the top of the body 1 near the outer shell 4, and a slider 10 is slidably connected inside the slide groove 20. The other end of the slider 10 is fixedly connected to the top side of the collection box 2. The slider 10 is used to limit the collection box 2.

[0038] The top of the rotating table 5 is fixedly connected to the rotating shaft 3, and the other end of the rotating shaft 3 is fixedly connected to the auxiliary frame 7. The auxiliary frame 7 assists the limit block 21 to fix the centrifugal channel 8.

A test tube containing a biological sample is placed into the centrifugal channel 8 , and the cover plate 6 is flipped over to seal the cavity 18 .

[0040] The four corners of the bottom end of the body 1 are fixedly connected with threaded sleeves 25, and the interiors of the multiple threaded sleeves 25 are threadedly connected with threaded rods 9. The height of the body 1 can be adjusted by turning the threaded rods 9 by hand. When the position where the centrifuge is placed is uneven, the multiple threaded rods 9 under the body 1 can be rotated, and the length of the threaded rods 9 extending out of the threaded sleeves 25 can be adjusted according to the height of the desktop, thereby adjusting the level of the body 1.

[0041] Working principle: when it is necessary to separate cells from biological samples, the centrifugal channel 8 can be placed into the groove 23, and then the spring 24 can be used to push the limit block 21 into the limit groove 22 to fix the centrifugal channel 8, and then the test tube containing the biological sample can be placed into the centrifugal channel 8, and the cover plate 6 can be flipped to seal the cavity 18, and then the rotating table 5 can be started to rotate, and the rotation of the rotating table 5 can be used to rotate the test tube inside the upper centrifugal channel 8 and generate centrifugal force, so as to separate cells from the biological sample inside the test tube. When separating cells from biological samples in test tubes of different types, the centrifugal channel 8 can be pulled upward to take the centrifugal channel 8 out of the groove 23, and then the centrifugal channel 8 of the corresponding test tube model can be placed. Put it into the groove 23, then pull the pull rod 14 to retract the fixing block 17 into the installation groove 16, and pull the collecting box 2 to one side to make the collecting box 2 extend out of the shell 4, and put the replaced centrifugal channel 8 into the placement groove 12, and reset the collecting box 2, and at the same time release the pull rod 14 to make the spring 15 push the fixing block 17 into the fixing hole 11 to fix the collecting box 2, and use the collecting box 2 to store the replaced centrifugal channel 8 so that the staff can quickly find it when using it next time. When the position where the centrifuge is placed is uneven, the multiple threaded rods 9 under the body 1 can be rotated, and the length of the threaded rod 9 extending out of the threaded sleeve 25 can be adjusted according to the height of the desktop, thereby adjusting the level of the body 1.
