DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0019] like Figure 1-Figure 3As shown, a cuvette holder compatible with multiple sizes is provided by an embodiment of the present invention, including a spring fixing member mounting seat 6, a spring fixing member 4 fixed to the upper end of the spring fixing member mounting seat 6, specifically, a spring fixing member mounting hole 5 is provided on the spring fixing member mounting seat 6, an M3 flat head screw 7 is provided in the spring fixing member mounting hole 5, and the M3 flat head screw 7 is threadedly connected to the lower end of the spring fixing member 4, and further includes: a cuvette positioning spring 2, the cuvette positioning spring 2 is fixed to the upper end of the spring fixing member 4, specifically, the upper end of the spring fixing member 4 is provided with a cuvette positioning spring fixing hole 3, The cuvette positioning spring piece 2 is penetrated by an M3 machine tooth pan head screw 1, and the M3 machine tooth pan head screw 1 is threadedly connected to the cuvette positioning spring piece fixing hole 3, and the cuvette positioning spring piece 2 extends to the side wall of the spring piece fixing part 4; and a spacing adjustment piece 8, the spacing adjustment piece 8 is provided with a long hole, and the spring piece fixing part mounting seat 6 is provided with a spacing adjustment piece mounting hole 10, and an M3 machine tooth pan head screw 2 9 is provided in the long hole of the spacing adjustment piece 8, and the M3 machine tooth pan head screw 2 9 is threadedly connected to the spring piece fixing part mounting seat 6; a cuvette fixing hole 11 is provided in the middle of the spring piece fixing part mounting seat 6.

[0020] In the embodiment of the present utility model, an M3 machine tooth pan head screw 1 is used to fix the cuvette positioning spring piece 2 on the cuvette positioning spring piece fixing hole 3. The cuvette positioning spring piece 2 is mainly used to ensure the repeated positioning accuracy of the cuvette. The spring piece fixing member mounting seat 6 is used to install the spring piece fixing member 4 and the spacing adjustment piece 8. The M3 flat head screw 7 is used to fix the spring piece fixing member 4 on the spring piece fixing member mounting seat 6. By adjusting the position of the long hole on the spacing adjustment piece 8 of the M3 machine tooth pan head screw 29, the position of the spacing adjustment piece 8 on the spring piece fixing member mounting seat 6 can be adjusted to adjust the cuvette fixing space suitable for different specifications and sizes. The cuvette fixing hole 11 is used to place the cuvette The cuvette holder is installed and fixed in the machine's sample chamber.
