[0002] At present, in the field of teaching, there are some subjects that have low student interest due to boring theoretical knowledge. For the above-mentioned subjects, it has been found through research that the use of teaching aids or block models related to the course and the corresponding courses can greatly improve student interest and teaching effect; in higher education teaching, display boards are indispensable teaching tools for most teachers. In the process of higher education teaching, display boards are usually needed for writing and then displaying information. With the rapid development of my country's higher education, the utilization rate of display boards has gradually increased.

By opening the first liquid-passing circular hole 1002 and the second liquid-passing circular hole 1007, the leaked ink is discharged from the rectangular concave shell 1001 and collected. The threaded torsion rod 1005 is rotated by the top torsion block 1008 to make it threadedly matched with the rectangular concave shell 1001. When the threaded torsion rod 1005 rotates and moves downward, it drives the outer square slide plate 1006 to move downward. The square slide plate 1006 moves down to the bottom and contacts the inner wall of the rectangular concave shell 1001 The first liquid hole 1002 is blocked at the same time, and the second liquid hole 1007 staggered with the first liquid hole 1002 is provided on the square slide 1006 to facilitate the square slide 1006 to cover and block it.

When the long cylinder 205 moves, it drives the bar The strip sponge board 206 fixed on the strip clamping rod 209 by the clamping hole 208 moves. When the strip sponge board 206 moves, it always contacts with the surface of the display whiteboard 1 and cleans it by wiping. The strip sponge board 206 is replaced by pushing the strip sponge board 206 and the strip clamping rod 209 upward to disengage it from the clamping hole 208. The strip sponge board 206 at different positions on the surface of the long cylinder 205 is contacted with the display whiteboard 1 by rotating the long cylinder 205 so that the top open thread groove 207 and the thread block 204 are rotated. The strip sponge board 206 is fixed horizontally by inserting the strip clamping rod 209 into the strip clamping hole 208 for insert-type clamping. After the inclination angle of the display whiteboard 1 is adjusted, the electric push rod 90 is used to adjust the inclination angle of the display whiteboard 1. The circular push plate 901 is pushed to drive the frosting block 904 on one side to contact the side of the display whiteboard 1. The movement of the circular push plate 901 allows the frosting block 904 to push and fix the two sides of the display whiteboard 1. The frosting block 904 is arranged on one side of the circular push plate 901 to increase the friction when in contact with the display whiteboard 1. When the circular push plate 901 moves toward the display whiteboard 1, it contacts the fan-shaped sponge block 906 and pushes the fan-shaped sponge block 906 to be tilted and bent toward the display whiteboard 1. When the circular push plate 901 pushes the fan-shaped sponge block 906, the surface of the frosting block 904 will be in wiping contact with the fan-shaped sponge block 906. The surface of the frosting block 904 on one side of the circular push plate 901 is wiped and cleaned by pushing the fan-shaped sponge block 906.By setting a side ring plate 905 on one side of the annular push plate 901 to support the inclined and curved fan-shaped sponge block 906, when the annular push plate 901 does not push the display whiteboard 1, the electric push rod 903 drives the annular push plate 901 to move back toward the concave bracket 3. When the annular push plate 901 moves back, the outer fan-shaped sponge block 906 gradually tilts and bends inward to the initial vertical state until the four fan-shaped sponge blocks 906 are restored to the vertical state to cover the inner wall of the inclined ring plate 902. To prevent the occurrence of the above problems, a plurality of partition plates 1004 are arranged in the rectangular concave shell 1001 to divide the area into a plurality of areas for placing the tools used for teaching on the square slide plate 1006. When the tools with ink accidentally leak ink, the ink will pass through the liquid-passing circular hole 2 1007 opened on the direction slide plate and fall on the bottom of the inner wall of the rectangular concave shell 1001 and continue to pass through the liquid-passing circular hole 1002 and fall into the bottom inclined shell 1003 to be collected and wait for recycling. 1007 allows the leaked ink to be discharged from the rectangular concave shell 1001 and collected. The threaded torsion bar 1005 is rotated by the top torsion block 1008 to make it threadedly matched with the rectangular concave shell 1001. When the threaded torsion bar 1005 rotates and moves downward, it drives the outer square slide 1006 to move downward. When the square slide 1006 moves down to the bottom and contacts the inner wall of the rectangular concave shell 1001, it blocks the liquid-passing circular hole 1002. The second liquid-passing circular hole 1007 is convenient for the square slide 1006 to cover and block it. When the threaded torsion bar 1005 rotates, the small sleeve block 1009 and the arc scraper 1010 on the outside are driven to rotate together. When the arc scraper 1010 rotates, the side of the partition plate 1004 and the inner wall of the rectangular concave shell 1001 are scraped and cleaned. Through the rotational connection between the square slide 1006 and the threaded torsion bar 1005, the bottom of the arc scraper 1010 always scrapes and cleans the top surface of the square slide 1006 when it rotates.
