The power adjustment mechanism 4 can adjust the centrifugal speed power, and then the centrifuge tube can be quickly capped by the capping mechanism 2.

[0043] The positioning mechanism 3 includes a centrifugal seat 31 rotatably connected to the inside of the separator 1, a plurality of placement cylinders 32 are arranged inside the centrifugal seat 31, a plurality of placement tube seats 321 are fixedly connected to the inner side of the placement cylinder 32, a limited positioning block 314 is slidably connected to the inside of the placement cylinder 32 and located on one side of the placement tube seat 321, a positioning arc plate 320 is fixedly connected to one side of the limited positioning block 314, a second slide groove 315 is opened inside the limited positioning block 314, a one-way angle block 316 is slidably connected to the inner wall of the second slide groove 315, and a second spring 316 is fixedly connected to the top of the one-way angle block 316 7.

When the nut 37 touches the touch switch 311, an internal alarm is used to remind the user, and then the movement is stopped. The position of the driving disk 310 can be limited by the nut 37, and then the threaded rod 38 is rotated to drive the threaded disk 39 to move upward, and then the remaining three second racks 35 in the lower position can be moved to the corresponding position after adjustment with the second rack 35 in the higher position through the threaded disk 39.

[0050] During use, when the position of the centrifuge tube needs to be fixed, the fourth electromagnet 326 is energized to attract the third electromagnet 313 to move downward, so that the position of multiple centrifuge tubes can be fixed. When the position of the centrifuge tube needs to be unlocked, the fifth electromagnet 327 and the sixth electromagnet 328 have the same magnetic pole facing each other, and then when the fifth electromagnet 327 and the sixth electromagnet 328 are energized, the repulsive force generated pushes the lifting rod 325 to move upward, and the upward moving lifting rod 325 drives the limiting fixing block 323 to slide upward in the third slide groove 322 to compress the fourth spring 324.
