[0031] Working principle: we open the cover plate 2, and then put the organic matter to be tested in the test tube, and then put multiple test tubes of different organic matter between a pair of arc plates 9, and then after the arc plate 9 is pushed, the sliding column 8 is pushed to slide on the inner wall of the fixed cylinder 5, and then the semicircular block 7 is pushed to slide on the inner wall of the fixed cylinder 5, and can squeeze the spring 16, so that the spring 16 can store elastic potential energy, and then give the arc plate 9 a reverse force to fix it. The operation is simple, just insert the tube to be tested between a pair of arc plates 9, and the strip plate 10 will provide support for the test tube and perform nitrogen content analysis and detection;

[0032] And when the movement is actually mixed with the organic matter, the rotating column 11 is driven to rotate by holding the turning handle 12 to apply a rotating force, thereby driving the circular plate 14 to rotate on the inner wall of the analyzer housing 1 to limit it, and at the same time, it will also drive the eccentric wheel 13 to rotate, and then push the connecting plate 15 to slide upward, thereby driving the sliding rod 16 to slide on the inner wall of the strip plate 10 to limit it, and then push the rubber plate 18 to slide upward and compress the spring 2 17, so that the spring 2 17 can store elastic potential energy, and then give the rubber plate 18 a reset force, quickly provide power to reset the rubber plate 18 and hit the strip plate 10, so that the test tube can be vibrated to accelerate the mixing of reagents and organic matter.
