[0028] Working principle: In use, the user first limits the base plate 2 by hand and opens the cover plate 1. Simultaneously, the connecting shaft 11 rotates inside the fixed seat 23, driving the spring 24. After opening, the user places the paper to be written on on the upper surface of the base plate 2 and releases the cover plate 1. Due to the action of the spring 24, the cover plate 1 returns to its original position and closes, thus achieving the folding function. Simultaneously, the outer surface of the cover plate 1 presses against the inclined surface in the elastic plate 21, causing the elastic plate 21 to deform and bend. Once the cover plate 1 clamps and limits the paper, the paper... The elastic plate 21 is bent and then reset, locking the cover plate 1. This achieves the function of limiting the paper's position when the user writes, and the phenomenon of the paper's placement position moving occurs. When it needs to be opened, the user pulls the connecting rod 22 to make the elastic plate 21 bend and separate from the cover plate 1, making it easy to open the cover plate 1 and take out the paper. After the user finishes writing, the pen is placed in the placement box 43, and the L-shaped end cap 45 is pushed to close, so that the magnetic block 46 is magnetically fixed to the placement box 43. The setting of the fixing block 42, the lanyard hole and the hanging rope 7 makes it convenient for the user to carry.
