[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figs. 1-2 In order to achieve the purpose of placing different cuvettes, this embodiment provides the following technical solution, specifically disclosing: a square-shaped outer shell 1, with a corresponding support base 2 at the bottom of the outer shell 1, and a first placement groove 3, a second placement groove 4, a third placement groove 5, and a fourth placement groove 6 inside the outer shell 1. The upper ends of the first placement groove 3, the second placement groove 4, the third placement groove 5, and the fourth placement groove 6 all penetrate the outer shell 1. The length of the first placement groove 3 is 10mm, the length of the second placement groove 4 is 20mm, the length of the third placement groove 5 is 30mm, and the length of the fourth placement groove 6 is 50mm. There are two sets of the first placement groove 3, the second placement groove 4, the third placement groove 5, and the fourth placement groove 6. The first placement groove 3 corresponds to the fourth placement groove 6, and the second placement groove 4 corresponds to the third placement groove 5. Light inlets 7 are provided on both the left and right sides of the outer shell 1. A lower buckle 12 is fixedly installed on the outside of the side of the support base 2, and an upper buckle 13 is fixedly installed on the outside of the side of the outer shell 1. The upper buckle 13 and the lower buckle 12 are mutually engaged and fixed.

[0026] When using the device, the outer shell 1 and the support base 2 are first fixedly installed together by the interlocking action between the upper buckle 13 and the lower buckle 12 to form a whole. Then, the whole is placed on the testing equipment (such as a spectrophotometer). Next, the cuvette to be tested is placed in the corresponding placement slot (the common standard sizes of cuvettes are 10mm, 20mm, 30mm, and 50mm). The first placement slot 3, the second placement slot 4, the third placement slot 5, and the fourth placement slot 6 correspond to different sizes and are used to place cuvettes of different sizes. Then, the light source in the testing equipment shines on the cuvette through the light inlet 7 to achieve the purpose of testing.

[0027] Example 2: Please refer to Figs. 3-6 In order to achieve a better fixing effect for the contrast coloring cuvette, this embodiment provides the following technical solution, which specifically discloses: a first compression spring 8 is fixedly installed inside the first placement groove 3, and the first compression spring 8 is set as a right-angle bent structure; a second compression spring 9 is fixedly installed inside the second placement groove 4, the third placement groove 5 and the fourth placement groove 6, and two second compression springs 9 are provided inside the fourth placement groove 6; an auxiliary compression block 10 for assisting uniform force is provided inside the third placement groove 5 and the fourth placement groove 6, and a compression spring 11 is fixedly installed between the auxiliary compression block 10 and the inner wall of the outer shell 1.

[0028] When the cuvette is placed in the first placement slot 3, it is pressed and fixed by the first compression spring 8 inside the first placement slot 3. The right-angle bending structure of the first compression spring 8 fixes the corner position of the cuvette. The second placement slot 4, the third placement slot 5 and the fourth placement slot 6 are pressed and fixed by the second compression spring 9. The fourth placement slot 6 is provided with two second compression springs 9 to achieve a more stable fixing effect. At the same time, the auxiliary compression blocks 10 inside the third placement slot 5 and the fourth placement slot 6 adhere to the surface of the cuvette under the compression action of the compression spring 11. The compression action of the auxiliary compression blocks 10 makes the surface of the cuvette more uniformly stressed.
