The teacher can pull the left partition block 19 outward to move the drawer 17 out of the support platform 9. By adding a drawer to the support platform 9, additional storage space can be provided for the teacher. The teacher can organize and place teaching-related documents, stationery and other items in the drawer 17, which is convenient for the teacher to find the required teaching materials and improve teaching efficiency. In the process of pulling the partition block 19 to move, the movable plate 12 hinged to the partition block 19 will drive the slider 13 to slide inside the connecting sleeve 10, and when the plug block 15 inside the slider 13 moves to the slot 11, the plug block 15 lacks a limit and will move to the slot 11 under the action of the spring 16. 1 moves inside the support platform 9, thereby blocking the slot 11, and limiting the moving range of the spacer 19 by the slot 11 to ensure that the spacer 19 stops at a specific position, so as to complete the limiting and fixing of the movable plate 12, and then complete the stable support of the spacer 19. When it is necessary to move the drawer 17 into the support platform 9, by pressing the plug block 15 inwardly, the plug block 15 moves to the inside of the slider 13, and the drawer 17 can be moved into the support platform 9. The writing board 18 can also be moved out through the above operation. Installing the writing board 18 on the support platform 9 can provide an additional writing platform for the teacher. The teacher can record important information and write down lesson preparation notes on the writing board 18. By hiding the drawer 17 and the writing board 18 inside the support platform 9, the device can be hidden when not in use. To reduce the floor space occupied, the teacher can place the book on the placement board 20, then open the book, and press the magnets 26 on both sides of the opened book, and fix the book through the cooperation of the magnets 26 and the magnet plate 25, so that the book remains in an open state, which is convenient for the teacher to check the contents of the book and ensure that the book will not be easily closed or slipped. In the process of using the placement board 20, the teacher can rotate the forward and reverse screw rods 24 inside the two tilting sleeves, and then gradually move the forward and reverse screw rods 24 to the inside of the two tilting sleeves. By rotating the forward and reverse screw rods 24, the angle of the placement board 20 can be adjusted, which is convenient for the teacher to find the most comfortable reading angle. The teacher can choose the most suitable reading angle according to his or her personal needs and comfort.
