Embodiment Construction
[0010] A book-leaf blackboard, comprising an outer frame (1), a chalk slot (2), a loose-leaf blackboard (3), a loose-leaf fixing ring (4), and a fixing shaft (5). Wherein, the fixed shaft (5) is installed and fixed at the center of the entire blackboard, and the loose-leaf blackboard (3) is connected together by the loose-leaf fixing ring (4). When using it, select the loose-leaf blackboard of the corresponding subject and open it to write on the classroom blackboard. If the current loose-leaf blackboard is not enough, you don’t need to erase it, just turn another page and continue writing. In this way, it not only saves valuable time in the classroom, but also facilitates the rewriting of important and difficult notes for students after class, improving the efficiency of teaching and learning.
