Abstract

An adjustable puzzle table, comprising a frame. Both sides of the frame are provided with multiple drawers, and the middle part of the frame is provided with multiple drawer spring mechanisms, which cooperate with the drawers to assist in ejecting the drawers from the drawer cavities. The back of the frame is rotatably provided with an adjustable support mechanism for supporting the frame and enabling adjustment of the frame's tilt angle. The bottom of the adjustable support mechanism is provided with a rotating component, thereby allowing the puzzle table to rotate 360 degrees horizontally. The front end of the frame is provided with an adjustable hanging rack for hanging posters, placards.
