The above-mentioned setting is so that the utility model discloses the piece is taken to last of supplementary table can adapt to the lower piece of taking of co-altitude to make the fixed effect of supplementary table better.

Preferably, the front end face of the rear desk plate is arranged in a cambered surface structure. The arrangement reduces the contact area between the front table board and the rear table board, so that the rear end of the front table board is turned upwards.

Preferably, the outer plate has a rear end surface formed with a lifting groove opening rearward. The arrangement is convenient for students to lift the outer plate.

The utility model has the advantages of adjustable inclination angle of the desk plate, standardized posture of students during writing and reading, and improved comfort of the students.
