The teacher takes off second disc 15, then put twenty six letter cards on fixing device 12, again control fixing device 12 and clip the letter card, after pressing from both sides, the teacher puts back second disc 15 normal position, the student can rotate carousel 19, drive first pivot 4 and rotate, thereby drive middle first gear 7 and rotate, second gear 8 through the left and right sides drives the first gear 7 rotation of the left and right sides, and then drive the second pivot 5 rotation of the left and right sides, drive first disc 10 through bolt 9 and rotate, the letter card rotates thereupon, extract the letter card. When the letter cards rotate to correspond to the first arc-shaped opening 17 and the second arc-shaped opening 18, the student stops rotating the rotary disc 19, then letters on the letter cards corresponding to the first arc-shaped opening 17 and the second arc-shaped opening 18 are combined into English words, the more English words are formed, the more English words are learned by the student, the less English words are formed, and the less English words are learned by the student. Therefore, the student can manually operate the chair, and the chair is high in interestingness, so that the student can be prevented from feeling irritated.
The teacher puts the twenty-six letter cards into the twenty-six third cavities 121, respectively, the letter cards press the pressing frame 125, the first compression springs 124 are compressed, so that the letter cards can be pressed, and the students can see the letters on the letter cards through the transparent plate 122.
When needs block second arc mouth 18, the student stirs pull rod 24 forward, drives cowl 23 and moves forward to drive iron plate 25 and move forward, when iron plate 25 moves forward and magnet 26 contact, magnet 26 can catch iron plate 25, make cowl 23 can not remove easily, cowl 23 can block second arc mouth 18, make the student can't see the letter on the letter card through second arc mouth 18, thereby can be applicable to the student of different grades.
The stop lever 28 can block the placing plate 14 to prevent the placing plate 14 from falling out of the fourth cavity 13, when the second disc 15 needs to be taken down, a teacher pulls the second disc 15 upwards to drive the placing plate 14 to move upwards, when the placing plate 14 moves upwards to be in contact with the stop lever 28, the stop lever 28 is pushed to move outwards, the second compression spring 29 is compressed, and when the placing plate 14 moves upwards to be separated from the stop lever 28, the stop lever 28 is reset inwards under the action of the second compression spring 29.
The student can stir the turning handle 32 downwards, stirs the turning handle 32 to vertical state, then holds the turning handle 32 and rotates the carousel 19, so, can make things convenient for the student to rotate the carousel 19, when need not rotate the carousel 19, the student upwards stirs the turning handle 32, stir the turning handle 32 to the horizontality can.
The above description is only an example of the present invention and is not intended to limit the present invention.
