[0002] Electrolyte analyzer is a kind of instrument for determining the concentration of various electrolytes (such as sodium, potassium, calcium, chlorine, etc.) in solution, and is widely used in medical, environmental monitoring, food and chemical industry. Through accurate electrochemical analysis technology, electrolyte analyzer can provide fast and accurate ion concentration measurement, help detect the electrolyte level in blood, urine, drinking water and other samples, to support clinical diagnosis, quality control and environmental monitoring and other applications.

[0003] For example, Chinese utility model patent (CN212780622U) discloses a multi-channel electrolyte analyzer, which records: "the utility model can stop the rotation of the second rotating disc by the friction ring on the double-head air cylinder, so that it will not continue to rotate due to inertia; the spring plate can clamp the glass tube, so that it can adapt to different sizes of glass tube, and will not shake due to small diameter of glass tube, so that the liquid in the glass tube will not spill." It also records: "the rotating device in the multi-channel electrolyte analyzer cannot stop rotating immediately when it stops rotating, and will continue to rotate due to inertia, so the rotating device cannot stop rotating accurately, which will affect the sampling of the equipment."

[0004] In summary, the first reset spring and spring plate are used to clamp and fix the glass tube in the prior art, but this method has the following technical problems: the spring plate can tightly adhere to the outside of the glass tube under the elastic force of the first reset spring, which will cause difficulty in taking out the glass tube from the first rotating disc when placing and taking out the glass tube due to friction between the spring plate and the glass tube, and reduce the installation and taking-out efficiency of the glass tube. Therefore, the present application provides a carousel device for electrolyte analyzer to solve the technical problems mentioned in the above patent and provide a new technical solution.
