10. The use method of the high school teacher-used high-safety intelligent chemical experiment table is characterized by comprising the following steps of: firstly, pouring a reagent into a beaker (22);
secondly, controlling a first motor (10) to drive a first threaded rod (11) to rotate into a first barrel of a telescopic rod (13) through a control assembly, controlling the telescopic distance of the telescopic rod (13), and further adjusting the shaking amplitude of the shaking table (9);
thirdly, controlling a second motor (14) to drive an eccentric balancing weight (15) to rotate through a control assembly to drive a shaking table (9) to shake;
step four, placing the test tube with the reagent in the C-shaped elastic clamping piece (29);
fifthly, a first electric push rod (7) is controlled by a control assembly to push the transparent protection frame (5) to slide out of the water tank (3), a frame-shaped rubber scraper scrapes water on the inner wall of the transparent protection frame (5), the transparent protection frame (5) slides out of the first notch (2), and the top end of the transparent protection frame (5) is higher than the operating platform (1);
sixthly, controlling a second electric push rod (26) through the control assembly to adjust the height of the test tube;
seventhly, controlling a third electric push rod (28) through a control assembly, and adjusting the distance between the test tube and the beaker (22);
step eight, controlling a fourth motor (28) to drive a third electric push rod (28) and the test tube to rotate through a control assembly, and pouring the reagent in the test tube into the beaker (22).
