The clip 2 is provided with a plurality of connecting portions, arranged sequentially from bottom to top, for removably connecting to the edges of the small-hole plate 3, the medium-hole plate 4, or the large-hole plate 5. The small-hole plate 3, the medium-hole plate 4, and the large-hole plate 5 are movable up and down relative to the clip 2. In this embodiment, the small-hole plate 3, the medium-hole plate 4, and the large-hole plate 5 are named based on the relative sizes of the sockets of each plate. The clip 2 is disposed vertically.

[0024] The test tube rack of the present invention is provided with a clamping strip 2 on a bracket 1 and a small-hole plate 3, a medium-hole plate 4 and a large-hole plate 5 are sequentially provided from bottom to top. The small-hole plate 3, the medium-hole plate 4 and the large-hole plate 5 can be moved up and down relative to the clamping strip 2, so as to adjust the height of each hole plate and the distance between adjacent hole plates. The insertion holes of the small-hole plate 3, the medium-hole plate 4 and the large-hole plate 5 have different apertures and can be used for inserting test tubes or other test tubes of different specifications. When in use, the upper hole plate can cooperate with the lower hole plate to fix the test tube inserted into the lower hole plate to prevent the test tube from being heated unevenly due to the movement of boiling water. The upper hole plate can press the tube cover to prevent the tube cover from bouncing off and the sample from splashing out. The test tube rack is suitable for water bath heating of various test tubes, especially boiling water bath heating, and is simple to operate, convenient and flexible to use, safe and reliable, and has a wide range of applications.

[0025] Furthermore, the edges of the small-hole plate 3, the medium-hole plate 4, and the large-hole plate 5 are each provided with a plurality of snap-in interfaces. The number of the clip strips 2 is the same as the number of snap-in interfaces, and the snap-in interfaces snap-in with the connecting portions of the corresponding clip strips 2. In this embodiment, each hole plate is provided with four snap-in interfaces, and the snap-in interfaces snap-in with the corresponding clip strips 2, making the connection more stable.

[0026] Furthermore, both sides of the clip strip 2 are provided with a plurality of serrated protrusions 21 arranged in sequence from bottom to top, and two adjacent serrated protrusions 21 above and below form a connecting portion, and the clip interfaces of the small hole plate 3, the medium hole plate 4, and the large hole plate 5 are respectively clipped with the connecting portion of the corresponding clip strip 2. The opposite sides of the clip strip 2 are sequentially arranged with a plurality of serrated protrusions 21. When in use, the clip interfaces are clipped with two adjacent serrated protrusions 21 above and below on one side of the clip strip 2 and two adjacent serrated protrusions 21 above and below on the other side of the clip strip 2 to fix the position of the orifice plate. When the height of the orifice plate needs to be adjusted, the clip interfaces are disconnected from the connecting portion or the orifice plate is moved up or down.

[0027] Furthermore, the bracket 1 includes a fixing ring 12 and a plurality of spaced-apart columns 11, each of which is fixedly connected to the fixing ring 12. The number of the clips 2 is the same as the number of the columns 11, and the clips 2 are fixedly connected to the inner sides of the corresponding columns 11. In this embodiment, the number of the columns 11 and the clips 2 is preferably four, which provides a simple structure and a stable connection. Those skilled in the art can adjust the number of columns 11, clips 2, and card interfaces according to actual needs.

[0028] Furthermore, the number of the first jacks 31, the second jacks 41, and the third jacks 51 decreases in sequence. The small-hole plate 3, the medium-hole plate 4, and the large-hole plate 5 all include a non-hollowed-out area and a hollowed-out area in which the first jacks 31, the second jacks 41, and the third jacks 51 are respectively provided. The first jacks 31 are located directly below the non-hollowed-out area of the medium-hole plate 4, and the second jacks 41 are located directly below the non-hollowed-out area of the large-hole plate 5. During use, according to actual needs, the cap of the test tube inserted into the first jack 31 can be pressed by the medium-hole plate 4, and the cap of the test tube inserted into the second jack 41 can be pressed by the large-hole plate 5. This can secure the test tube and prevent the cap from popping open, thereby preventing the sample in the tube from splashing out.

[0029] Furthermore, there are multiple fixing rings 12, which are spaced apart from each other from bottom to top, and each column 11 is fixedly connected to the multiple fixing rings 12. In this embodiment, there are two fixing rings 12, which are respectively located at the upper and lower ends of the bracket 1. The fixing ring 12 located at the lower end of the bracket 1 is connected to the upper end of the column 11, and the fixing ring 12 located at the lower end of the bracket 1 is connected to the lower end of the column 11. The clamping strip 2 is connected to the inner annular surface of the fixing ring 12. Due to the above-mentioned structural arrangement, the fixing ring 12 can fix the column 11, and the clamping strip 2 is firmly connected to the column 11 and the fixing ring 12.

[0030] Furthermore, the small hole plate 3, the medium hole plate 4 and the large hole plate 5 are all circular plates, the fixing ring 12 is a circular ring, and the multiple columns 11 are distributed in a circular array, which is firmly connected and easy to use.
