[0039] The display board 2 is located inside the writing board 1. A groove 9 is provided on the inner wall of the writing board 1. A ball 10 is connected to the groove 9 in a rolling manner. The ball 10 is evenly distributed inside the groove 9. The surface of the ball 10 is in contact with the bottom surface of the display board 2, which can reduce the friction between the bottom surface of the display board 2 and the inner wall of the writing board 1, thereby making it easier to slide the display board 2. A slide groove 3 is provided on the inner wall of the writing board 1. A slider 4 is fixedly installed on the top and bottom surfaces of the display board 2. The shape of the slide groove 3 and the slider 4 are both T-shaped. The slider 4 is located inside the slide groove 3 and is slidably connected to the slide groove 3. The T-shaped slider 4 and the slide groove 3 can limit the sliding position of the slider 4 on the one hand, avoiding the display The board 2 is detached from the inside of the writing board 1, and on the other hand, it is convenient for the slider 4 to slide in the slide groove 3. A fixing hole 5 is opened on the surface of the slider 4 on the top surface of the display board 2, and a fixing rod 6 is inserted on the top surface of the writing board 1. The fixing rod 6 matches the shape and size of the fixing hole 5. The fixing holes 5 are evenly distributed on the surface of the slider 4, and a tension spring 7 is sleeved on the surface of the fixing rod 6. A pull plate 8 is fixedly installed on the top of the fixing rod 6. Only by pulling the pull plate 8, the pull plate 8 can drive the fixing rod 6 to move. At the same time, the pull plate 8 applies an external force to the tension spring 7, so that the tension spring 7 drives the pull plate 8 to reset when it automatically recovers. Then the fixing rod 6 can be inserted into different fixing holes 5 to adjust the position of the display board 2.

[0040] A limit block 14 is fixedly installed on the back of the writing board 1. The shape of the limit block 14 and the limit slot 1501 are both T-shaped. The limit block 14 is located inside the limit slot 1501 and is slidably connected to the limit slot 1501. When the writing board 1 needs to be moved, slide the writing board 1 upward, take the limit block 14 out of the limit slot 1501, and then invert the limit slot 1501 above the limit block 14, and slide the limit slot 1501 to the bottom of the limit block 14. At this time, the writing board 1 can be easily moved. A rotating component 15 is provided on the back of the writing board 1. The rotating component 15 includes a limit slot 1501 and a support plate 1502. Anti-slip particles 1508 are fixedly installed on the bottom surface of the support plate 1502, and a counterweight block 1509 is provided on the top surface of the support plate 1502. The counterweight block 1509 is a water tank The weight of the support plate 1502 can be increased by pouring water into the counterweight 1509. At the same time, the weight of the counterweight 1509 can be reduced by pouring out the water in the counterweight 1509. The support plate 1502 is located below the limiting groove 1501. A turntable 1503 is fixedly installed at the bottom of the limiting groove 1501. A positioning groove 1504 is provided on the surface of the turntable 1503. The positioning grooves 1504 are distributed in a circular array on the surface of the turntable 1503. A circular groove 1505 is provided on the top surface of the support plate 1502. A spring 1506 is fixedly installed on the inner wall of the circular groove 1505. A positioning block 1507 is fixedly installed on one end of the spring 1506. The shape and size of the positioning block 1507 match those of the positioning groove 1504. The positioning block 1507 is distributed in a circular array inside the circular groove 1505.

[0041] Working principle: When using the display board 2, first manually pull the pull plate 8 so that the pull plate 8 drives the fixing rod 6 to move, and at the same time, the pull plate 8 applies external force to the tension spring 7 until the fixing rod 6 is taken out of the fixing hole 5, and then pull the display board 2 outward, and the display board 2 drives the slider 4 to slide inside the slide groove 3. At the same time, the bottom surface of the display board 2 rubs against the surface of the ball 10, so that the ball 10 rolls inside the groove 9, which can reduce the friction between the bottom surface of the display board 2 and the inner wall of the writing board 1, thereby facilitating the pulling of the display board 2 until the display board 2 is completely extended from the writing board 1. At this time, release the hand pulling the pull plate 8, and under the pull force of the tension spring 7 itself, the tension spring 7 drives the pull plate 8 to move downward, and the pull plate 8 then drives the fixing rod 6 to move until the fixing rod 6 is inserted into the corresponding fixing hole 5, at which point the position of the display board 2 can be fixed, and then the adjusting block 1302 is manually rotated, and the adjusting block 1302 drives the screw rod 1301 to rotate. Since the cavity 11 and the side block 12 are both provided with threads that mesh with the screw rod 1301, the screw rod 1301 drives the universal wheel 1303 to move until the universal wheel 1303 on the side of the writing board 1 and the universal wheel 1303 on the back of the display board 2 are adjusted to a suitable height. At this point, the display board 2 and the writing board 1 can be used at the same time. When use is finished, the writing board 1 or the display board 2 can be moved by pushing it. When only the writing board 1 is used, the pull plate 8 is pulled again to store the display board 2 inside the writing board 1, and then the limiting groove 1501 is moved from the limiting block 14 The writing board 1 is then detached from the back of the writing board 1 by sliding the limit groove 1501, that is, sliding the limit groove 1501 so that the limit groove 1501 is detached from the back of the writing board 1, and the support plate 1502 is placed on the ground. The anti-skid particles 1508 on the bottom of the support plate 1502 can increase the friction between the bottom of the support plate 1502 and the ground to prevent the writing board 1 from sliding and deviating during use. Water is added to the counterweight block 1509 to increase the weight of the support plate 1502, and then the writing board 1 is lifted so that the limit block 14 on the back of the writing board 1 is opposite to the limit groove 1501, and the limit block 14 is slid into the limit groove 1501 until the limit block 14 reaches the bottom of the limit groove 1501. At this time, the writing board 1 can be fixed on the top of the support plate 1502. When the angle of the writing board 1 needs to be adjusted, just The writing board 1 needs to be rotated, and the writing board 1 drives the limit block 14 to move, and the limit block 14 drives the limit slot 1501 to move, and the limit slot 1501 drives the turntable 1503 to move, and the turntable 1503 immediately drives the positioning slot 1504 on its surface to move, and squeezes the positioning block 1507, and the positioning block 1507 squeezes the spring 1506 at the same time, until the writing board 1 is adjusted to a suitable position, and then the rotation of the writing board 1 is stopped. At this time, the positioning block 1507 is opposite to the positioning slot 1504, and the spring 1506 loses the external force squeezing. Due to its own elastic force, it drives the positioning block 1507 to bounce outward until the positioning block 1507 is embedded in the positioning slot 1504. At this time, the angle of the turntable 1503 can be fixed, and the writing board 1 is also fixed.
