[0003] The existing learning devices for English teaching still have great defects when in use. The existing learning devices for English teaching can provide teachers with a small teaching writing space, and it is not convenient for different students to write the content to be tested on the learning devices. It is not convenient for teachers to explain and correct the content written by different students to be tested on the learning devices. The teaching board on the existing learning device is easy to collide and shake with other components of the device during flipping and use, resulting in dust written on the teaching board being easy to fall off, and the dust is easy to fall and fly into the air to cause environmental pollution, seriously affecting the health and safety of teachers in teaching and students in learning. When teachers use the learning device to teach English, students at different positions cannot see the learning content on the teaching board more clearly and conveniently. The teacher cannot use the learning device to divide students into different areas for PK teaching. The learning device cannot enhance the teaching interest and the enthusiasm of students to learn. After the learning device is used for writing chalk for a long time, there is no structure on the learning device to uniformly collect chalk dust, resulting in chalk dust being easily scattered into the air in large quantities, and it is not convenient to clean it uniformly.

[0022] A further technical improvement of the present invention is that the method for using the device specifically comprises the following steps:

[0023] Step 1: flip the inner support seat, place the inner support seat vertically, then screw the nut clockwise to fix the rotating arms at both ends, thereby fixing the inner support seat, and conduct English teaching by writing teaching content on the teaching board. After the teacher or student has fully used the writing area on one side of the teaching board, the teaching board is flipped around the rotating axis to write on the other side of the teaching board;

[0024] Step 2: The motor drives the turntable to rotate and adjust through the transmission shaft to change the direction of the teaching board facing the students, and by pushing the bracket, the second roller rolls in the second rolling groove, thereby adjusting the position of the teaching board facing the students to the left and right;

[0025] Step 3: By pulling the pull block, the drawer frame is pulled out, and the teacher or student writes the English words they want to learn and remember in the writing slot and then slides the covering slide to cover the written English words, so that the students can recall and learn and remember;

[0026] Step 4: The teacher uses a chalk eraser to erase the writing in the graffiti slot, and the chalk dust flows from the ash flow slot at one end of the graffiti slot into the ash storage bin for storage. The flip plate is opened, and the flip plate rotates around the hinge. The flip plate is adapted to the height of the ash storage bin, and the chalk dust stored in the ash storage bin is uniformly cleared.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The device is provided with four teaching boards at equal intervals. When in use, the inner support seat is turned over and placed vertically, and then the nut is screwed clockwise to fix the rotating arms at both ends, thereby fixing the inner support seat. English teaching is carried out by writing teaching content on the teaching board, and both sides of the teaching board can be written, ensuring that the device can provide a larger teaching writing space, and the four teaching boards are also more convenient for assessing different students. Different students write the assessed content on different teaching boards respectively, which is more convenient for teachers to explain and correct the content written by different assessed students. After the teacher or student has fully used the writing area on one side of the teaching board, the teaching board can be turned over more quickly and flexibly. The teaching board is turned around the rotating shaft, which is convenient for the teacher or student to write on the other side of the teaching board. In the process of the flipping activity, the teaching board will not collide or shake with other parts of the device, ensuring that the dust written on the teaching board is not easy to fall off, ensuring that less dust is scattered into the air, and ensuring that the teacher is safer and healthier when teaching and the students are learning.

[0029] 2. After the teacher writes the teaching content on one side of the teaching board, the teaching board is quickly turned over to cover the written content to the students, which is more convenient for students to learn by association and improve the quality of students' learning. The motor drives the turntable to rotate and adjust through the transmission shaft to change the direction of the teaching board facing the students. By pushing the bracket, the second roller rolls in the second rolling groove, so as to adjust the position of the teaching board facing the students to the left and right, ensuring that students at different positions can see the learning content on the teaching board more clearly and conveniently, and it is also more convenient for teachers to conduct PK teaching for students in different areas, which enhances the teaching interest and students' enthusiasm for learning and improves students' learning efficiency. In the process of rotation of the turntable, the first rollers on the two auxiliary components roll in the first rolling groove to cooperate with the rotation of the turntable, ensuring that the turntable and the components above the bracket are more stable and reliable during the rotation and adjustment process, thereby improving the service life of the device.

[0030] 3. By pulling the pull block, the drawer frame is pulled out, and the teacher or student writes the English words they want to learn and memorize in the writing slot and then slides the covering slide to cover the written English words, allowing the students to recall and learn. If they cannot recall, the covering slide is slowly slid in the opposite direction to expose the letters of the English words one by one, allowing the students to recall and memorize while exposing them. While enhancing the students' interest in learning, this associative memory method can make students' learning and memory more solid, and a number of writing slots are arranged side by side at equal intervals on the drawer frame to ensure that multiple words can be written on the drawer frame for learning and memorization, and a number of drawers are arranged in parallel between the four side partitions to ensure that the device can provide a larger English word teaching and writing space, which is more convenient for multiple students to memorize words.

[0031] 4. The teacher uses a chalk eraser to erase the writing in the graffiti slot, and the chalk dust flows from the ash flow slot at one end of the graffiti slot into the ash storage bin for storage, which is convenient for the unified collection of chalk dust and prevents a large amount of chalk dust from flying into the air and causing environmental pollution. By opening the flip plate, the flip plate rotates around the hinge, and the height of the flip plate is adapted to the ash storage bin, which is convenient for the unified removal of chalk dust stored in the ash storage bin.
