Through the setting of the buffer mechanism 7, when the sliding blackboard 5 slides toward the column 6, the sliding blackboard 5 contacts the buffer plate 705 and squeezes the spring 702 through the connecting rod 704. After being squeezed, the spring 702 shrinks and absorbs a large amount of force generated by the impact during the shrinkage process, thereby protecting the column and buffering the impact. In addition, the buffer rubber pad 706 further increases the buffering effect due to the characteristics of its own material.

[0022] Furthermore, the size of the positioning groove 701 matches the size of the positioning block 703, and four groups of connecting rods 704 and springs 702 are provided.

Through the setting of the sliding mechanism 4, when the display screen 3 needs to be used, the sliding blackboard 5 is first pushed, and the guide wheel 406 at this time will slide in the guide groove 403, so that the sliding blackboard 5 slides in the sliding groove 401, and the limiting block 404 will be restricted in the limiting groove 402, so as to limit the sliding blackboard 5. After the sliding blackboard 5 is moved, the display screen 3 can be used normally.

[0027] Furthermore, the size of the T-shaped block 804 is consistent with the size of the T-shaped slot 803, the position of the dust drop port 801 corresponds to the position of the blackboard 2, and through the setting of the T-shaped block 804 and the T-shaped slot 803, when in use, the T-shaped block 804 is limited by the T-shaped slot 803, thereby making the extraction of the collection box 805 more stable.

[0028] Working principle: when the display screen 3 needs to be used, the sliding blackboard 5 is first pushed, and the guide wheel 406 at this time will slide in the guide groove 403, so that the sliding blackboard 5 slides in the sliding groove 401, and the limit block 404 will be restricted in the limit groove 402, so as to limit the sliding blackboard 5. After the sliding blackboard 5 is moved, the display screen 3 can be used normally.
