[0027] The plug-in assembly includes two fixing frames 3, which are respectively welded to the outer walls of both sides of the shell 1. A sliding hole is provided on one side of the two fixing frames 3, and a round rod 5 is slidably connected in the sliding hole. A spring 4 is sleeved on the circumferential outer wall of the round rod 5, and the two ends of the spring 4 are respectively fixed to the fixing frame 3 and the round rod 5. Two pin holes 13 are provided on both sides of the third test tube rack 12, and the round rod 5 is plugged into the pin holes 13. The limiting assembly 1 includes a limiting groove 10, which is provided at the bottom of the second test tube rack 7. A limiting block 14 is welded on the upper surface of the first test tube rack 6, and the limiting block 14 is slidably connected to the limiting groove 10. The limiting assembly 2 includes a slide groove 8, which is provided at the bottom of the first test tube rack 6. A slider 11 is welded on the upper surface of the third test tube rack 12, and the slider 11 is slidably connected to the slide groove 8.

At the same time, because the third test tube rack 12 is against the round rod 5, the round rod 5 cannot be moved by the force of the spring 4. At this time, the slider 11 on the third test tube rack 12 will move in the slide groove 8. When the slider 11 moves to the other end of the slide groove 8, the third test tube rack 12 will drive the first test tube rack 6 to move through the slider 11. At this time, the upper limit block 14 of the first test tube rack 6 will move in the limit groove 10.

[0028] Two support columns 2 are fixed to the bottom of the third test tube rack 12 by bolts, so that the third test tube rack 12 moved out of the shell 1 is supported. After the third test tube rack 12 is completely pulled out, the support columns 2 will support the third test tube rack 12. Two avoidance grooves 9 are provided at the bottom of the shell 1 to avoid the two support columns 2.

[0029] Working principle: when it is needed, the round rod 5 is pulled to move so that the round rod 5 is disengaged from the pin 13 on the third test tube rack 12, and the round rod 5 will squeeze the spring 4 to contract, and the third test tube rack 12 can be pulled out of the shell 1. At the same time, because the third test tube rack 12 is against the round rod 5, the round rod 5 cannot be moved by the force of the spring 4. At this time, the slider 11 on the third test tube rack 12 will move in the slide groove 8. When the slider 11 moves to the other end of the slide groove 8, the third test tube rack 12 will drive the first test tube rack 6 to move through the slider 11. At this time, the upper limit block 14 of the first test tube rack 6 will move in the limit groove 10. When the limit block 14 moves to the other end of the limit groove 10, the third test tube rack 12 and the first test tube rack 6 are in a closed position. The rack 6 will be completely pulled out, and at this time the round rod 5 will be reset by the force of the spring 4 and inserted into another pin hole 13, thereby fixing the third test tube rack 12. At this time, the first test tube rack 6 will be fixed under the cooperation of the slider 11 and the slide groove 8 with the limit block 14 and the limit groove 10, and then the test tubes are placed in the first test tube rack 6, the second test tube rack 7 and the third test tube rack 12, and then the bidirectional screw rod 17 is rotated. The bidirectional screw rod 17 is engaged with the first U-shaped clamp frame 16 and the second U-shaped clamp frame 20 through the threaded engagement, which makes the first U-shaped clamp frame 16 and the second U-shaped clamp frame 20 move to clamp the test tube, so that it can be used to place test tubes of different sizes without replacing other test tube racks, thereby improving the use effect of the test tube rack.

[0030] In addition, the terms "installation", "setting", "connection" and "socketing" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements or components. Those skilled in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
