[0016] 1. The structure of the present invention is reasonable. When the side panels are stored, the side panels are rotated. A card plate is fixedly connected to the side panels. The card plate is moved to the inclined surface of the adjusting block by rotating the side panels. Then, the adjusting block is squeezed so that the card plate is clamped in the inside of the card slot. When the side panels are opened, the pull rod is pulled to drive the rotating ring to rotate through the fixed seat. The limit groove on the rotating ring slides on the sliding column to increase the stability of the rotating ring. The rotation of the rotating ring causes the guide groove to pull the shaft pin on the adjusting block to move, thereby facilitating the retraction of the adjusting block, so that the card plate is separated from the inside of the card slot, thereby facilitating the opening of the side panels.
