[0027] The height positioning component 5 includes: a connector 501, a connecting rod 502, a limiting block 503, a positioning block 504, and a spring piece 505.

[0028] The connector 501 is disposed above the support frame 3. There is a limiting groove 506 inside the top of the support frame 3. The connecting rod 502 is fixedly connected to the bottom end of the connector 501. The connecting rod 502 is slidably connected to the notch at the top of the limiting groove 506. The limiting block 503 is fixedly connected to the bottom end of the connecting rod 502. The limiting block 503 is slidably connected to the limiting groove 506. There are several positioning holes 507 on one side of the limiting groove 506. There is a limiting hole 508 on one side of the limiting block 503. The positioning block 504 is slidably connected inside the limiting hole 508. The positioning block 504 can be inserted into the inside of the positioning hole 507. The spring piece 505 is disposed inside the limiting hole 508. The spring piece 505 is used to support the positioning block 504.

[0029] Press the positioning block 504 to take it out of the positioning hole 507 and retract it into the limiting hole 508. At this time, pulling the connector 501 can adjust the overall height, so that a centrifuge tube rack can clamp and fix test tubes of different lengths, and the applicable range is wider.

[0030] The clamping ring component 6 includes: a fixed ring 601, a limiting shaft 602, a clamping ring 603, a fixed shaft 604, a spring 605, an adjusting ring 606, and a push button 607.

[0031] The fixed ring 601 is fixedly connected to the same side of the support frame 3 and the connector 501. A first chute 608 is provided inside the fixed ring 601. The limit shaft 602 is fixedly connected to the end of the first chute 608. The clamping ring 603 is slidably connected to the inside of the first chute 608.
