[0052] The implementation principle of an adjustable-height reading rack in this application embodiment is as follows:

[0053] Step 1: When the height needs to be adjusted, first unscrew the wing screw 9 counterclockwise, and pull the arc-shaped slide plate 8 outward. At this time, the arc-shaped slide plate 8 drives the insertion rod 11 to move backward, so that the large end of the insertion rod 11 moves away from the reserved hole 16 and inserts into the circular groove 10. Then, hold the movable column 5 in the fixed column 2 and move it upward. The movement of the fixed column 2 drives the insertion rod 11 to slide upward in the arc-shaped groove 6. At the same time, the arc-shaped slide plate 8 moves upward. Finally, after moving to the appropriate position, push the arc-shaped slide plate 8 forward to fit against the surface of the fixed column 2. At this time, the insertion rod 11 is inserted into the corresponding reserved hole 16. Pass the wing screw 9 through the arc-shaped slide plate 8, insert it into the threaded groove 7, and rotate it clockwise to tighten it. This fixes the height of the fixed column 2 and the movable column 5, thus raising the reading height of the bookshelf 3 and the book. The same operation is performed when it is necessary to lower it.

[0054] Step 2: When the page limiting function is needed, simply place the book on the book shelf 3, pull the moving rods 4 on both sides of the book shelf 3 up and down according to the thickness of the book, and then pull the adjusting rod 14 in the moving rod 4 up and down according to the thickness of the book and the position to be limited. As the adjusting rod 14 moves, it causes the slide rod 15 to slide up and down in the arc groove 12. The length and position functions can be selected according to actual needs, thereby increasing adaptability.
