DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3A conveniently foldable writing board comprises an upper writing board 1, the bottom of the upper writing board 1 is connected to a lower writing board 2 through a hinge, lower guide cylinders 3 are welded on both sides of the lower writing board 2, upper guide cylinders 4 are welded on both sides of the upper writing board 1, a sliding rod 5 is inserted between the upper guide cylinder 4 and the lower guide cylinder 3, and first elastic blocks 6 are bonded on both sides of the upper writing board 1, the first elastic blocks 6 are in contact with the sliding rod 5, and the design of the first elastic blocks 6 prevents the sliding rod 5 from falling off, and the sliding rod 5 is inserted between the lower guide cylinder 3 and the upper guide cylinder 4, so as to align the upper writing board 1 with the lower guide cylinder 3. The writing board 1 is fixed to the lower writing board 2, two second elastic blocks 7 are bonded to the top of the upper writing board 1, the second elastic blocks 7 are in contact with the lower writing board 2, the bottom of the upper writing board 1 and the top of the lower writing board 2 are bonded with first magnet blocks 8, the two first magnet blocks 8 attract each other, and the upper writing board 1 and the lower writing board 2 are fixed by the attraction of the first magnet blocks 8, and telescopic rods 9 are fixed on both sides of the lower writing board 2 by bolts, and the heights of the upper writing board 1 and the lower writing board 2 are adjusted by the telescopic rods 9 to meet different needs.
