[0003] However, when the metering device currently used drips chemical reagents into a container, due to the different heights of the containers, such as measuring cups, measuring cylinders and test tubes, etc., it is necessary to pick up the metering device as a whole and wait for the reagent to drip to the amount to be tested before putting it down. After dripping the reagent, it is currently necessary to manually observe whether there is more reagent dripping out, and then it is necessary to handle the reagent in the tube, and the overall operation steps are relatively cumbersome.

[0011] Compared with the above-mentioned background technology, the chemical reagent quantitative detection equipment provided by the present application includes a metering device with very mature technology today, and an extension mechanism and a sealing mechanism as core components. Its principle relies on extending the length of the liquid outlet pipe and changing the direction and height of the liquid outlet by rotating the bending pipe.
