[0004] To achieve the above purpose, the utility model provides a colorimetric tube fixing component for fixing the colorimetric tube in the jack of the sample tray, including:

[0005] A plugging part and a positioning part, one end of the plugging part is integrally connected to the positioning part. The plugging part is used to be inserted into the jack, the inner circumference of the plugging part can accommodate the colorimetric tube to pass through, and a flexible positioning ring is arranged on the inner circumference of the positioning part, and the inner diameter of the positioning ring is smaller than the outer diameter of the colorimetric tube.

[0015] The utility model provides a colorimetric tube fixing component, and its beneficial effects are as follows: The colorimetric tube fixing component has a plugging portion and a positioning portion. Through the plugging portion, it can be plugged into the jack of the sample tray to realize the fixing of the colorimetric tube fixing component on the sample tray. Through the positioning ring inside the positioning portion, the colorimetric tube inserted into its inside can be clamped and fixed.
