At the same time, the staff can rotate the angle of the adjusting rod 15 according to the refraction position of the sunlight, so that the first connecting rod 17 will pull the sunshade cloth 14 to slide in the middle part of the two groups of mounting frames 12 during the movement, until the middle part of the sunshade cloth 14 blocks part of the light on both sides of the blackboard body 1. When the sunshade cloth 14 needs to be stored in the middle part of the storage rod 13 again, the bottom of the storage rod 13 can be rotated. This step cooperates with the sunshade cloth 14 unfolded by the first connecting rod 17 to block part of the light on both sides of the blackboard body 1, thereby reducing the mirror reflection of external light after it hits the surface of the blackboard, which makes it difficult for teachers in some positions to see the fonts or training materials in the middle part of the blackboard body 1, thereby improving the effect of teacher training.

As shown in Figures 1, 2, 3 and 5, a slide bar 2 is slidably connected to the middle of the first connecting rod 17; a support block 21 is fixedly connected to the bottom of the slide bar 2; a plurality of groups of protrusions 22 are fixedly connected to the bottom of the support block 21; the protrusions 22 are arranged in a circular array at the bottom of the support block 21; a connecting plate 23 is fixedly connected to the bottom of the blackboard body 1; a plurality of groups of card grooves 24 matching the shape of the protrusions 22 are provided in the middle of the connecting plate 23; during operation, a slidable slide bar 2 is provided in the middle of the first connecting rod 17, so that when the first connecting rod 17 is unfolded, the downward gravity of the slide bar 2 as a whole is utilized to make the slide bar 2 and the support block 21 move and gradually approach the installation ground until a plurality of protrusions 22 contact the ground, thereby extending the first connecting rod 17 to a certain extent. The working position of the adjusting rod 15 is initially fixed. When the slide bar 2 needs to be stored, the staff can push the slide bar 2 into the first connecting rod 17 and at the same time, the multiple protrusions 22 at the bottom of the support block 21 are clamped in the matching grooves 24, so that the support block 21 is fixed and stored as a whole. This step, in conjunction with the support block 21 and the protrusions 22 in contact with the ground, can improve the situation when the slide groove 16 and the first connecting rod 17 are used. Due to the strong wind force in the outside world, the slide groove 16 as a whole shakes when working, resulting in a significant deviation in the shading angle of the sunshade cloth 14. At the same time, in conjunction with the grooves 24 inside the connecting plate 23, the support block 21 can be fixed as a whole, reducing the problem of the support block 21 slipping off the middle of the connecting plate 23.

As shown in Figure 3, two groups of brackets 3 are fixedly connected to the middle part of the slide bar 2; counterweight blocks 31 are fixedly connected to the ends of the brackets 3; the ends of the counterweight blocks 31 are arranged near the support block 21; when working, by arranging the brackets 3 and the counterweight blocks 31 at the bottom of the slide bar 2, when the support block 21 is close to the installation ground or the protrusion 22 is stuck in the slot 24, the position of the support block 21 can be reinforced as a whole by cooperating with the two groups of counterweight blocks 31. This step utilizes the gravity generated downward by the two groups of counterweight blocks 31 to further improve the stability of the support block 21 and the protrusion 22 when they are in contact with the ground, reduce the phenomenon of deviation in their positions, and at the same time improve the stability of the slot 24 when receiving the protrusion 22.

As shown in Figure 3, a plurality of connecting members 4 are fixedly connected to the bottom of the first connecting rod 17; a scraper 41 is fixedly connected to the bottom of the connecting member 4; the interior of the scraper 41 is inclined; the inner wall of the scraper 41 is in contact with the middle of the slide bar 2; during operation, by providing the scraper 41 at the bottom of the first connecting rod 17, when the slide bar 2 slides in the middle of the first connecting rod 17, the inclined surface in the middle of the scraper 41 will clean up some impurities in the middle of the slide bar 2. This step, in conjunction with the scraper 41, can improve the cleanliness of the middle of the slide bar 2 and reduce the problem of greater resistance when the slide bar 2 slides in the middle of the first connecting rod 17 due to the slide bar 2 being close to the ground and having more impurities attached to its surface.
