[0027] First, the teaching staff places the base 1 on the tabletop of the podium, then pulls the latch 12 outward to disengage the connection with the connecting plate 1201, then pulls the cover 10 upward to disengage the base 1, thereby exposing the vertical plate 3, and the cover 10 drives the cleaning block 14 to move upward, so that the cleaning block 14 wipes the dust and other impurities on the surface of the beads 7, thereby reducing the bacteria on the surface of the beads 7, and then moves a proper amount of beads 7 backward in turn, so that the remaining beads 7 form appropriate numbers, and then rotates the bracket turntable 4 and the symbol turntable 5 in turn, so that the numbers, brackets and symbols together form arithmetic problems, thereby facilitating the composition of any arithmetic problems for teaching staff, expanding the question-setting and The teaching staff then teaches the learner to solve the problem on the vertical board 3, and writes the answer on the writing board 8 after solving it. Before giving the next arithmetic problem, the teaching staff erases the answer on the writing board 8, and gives a new arithmetic problem, and asks the learner to write the answer to the arithmetic problem on the writing board 8. When the answer is correct, the teaching staff presses the button 15 backward, and the button 15 drives the oblique block Ⅰ1501 to move backward, and the spring Ⅰ1503 is stretched accordingly, and the oblique block Ⅰ1501 squeezes the oblique block Ⅱ16 to move rightward, and the spring Ⅱ1602 is compressed accordingly, so that the oblique block Ⅱ16 is separated from the thumb 1605. After the encouragement is completed, the teaching staff presses the thumb 1605 downward, and the spring III 1604 is compressed. Then, the button 15 is released, and the spring I 1503 is restored to its original state, so that the oblique block I 1501 drives the button 15 to move forward, so that the oblique block I 1501 stops squeezing the oblique block II 16, and the spring II 1602 is restored to its original state, so that the oblique block II 16 moves leftward to contact with the thumb 1605. The thumb 1605 contacts the vertical plate 3, and then the thumb 1605 is fixed in the vertical plate 3. After the teaching is completed, the teaching staff pulls up the sliding plate 9, so that the sliding plate 9 pushes the beads 7 forward to reset, which is convenient for the next question. Then the cover 10 is put back on the base 1 to dock with it, and then the latch 12 is pushed inward to engage with the connecting plate 1201, and then the cover 10 is fixed on the base 1 to improve the stability of the cover 10, and then the disinfection lamp 13 is started. The disinfection lamp 13 lights up to disinfect the vertical plate 3, the arc rod 6 and the beads 7, further reducing the bacteria on the beads 7 and avoiding a large number of bacteria on the hands of the teaching staff when they touch the beads 7.
