Through the transition arrangement of the arc surface 3-3 between the first limiting surface 3-1 and the second limiting surface 3-2, when the movable plate 2-2 rotates along the central axis of the rotating shaft 5, the collision part 4 simultaneously rotates along the central axis of the rotating shaft 5 along with the movable plate 2-2, and because the arc surface 3-3 and the rotating shaft 5 are coaxially arranged, when the movable plate 2-2 rotates from the horizontal position to the vertical position, the second collision surface 4-2 just can abut against the second limiting surface 3-2, so that the collision part 4 cannot interfere with the limiting part 3 in the movement process, and the structure is simple and reliable.

The contact part 4 comprises a limiting bolt 4-3 and a limiting nut 4-4, the limiting nut 4-4 is fixedly connected with the movable frame 9 through a connecting plate, the central axis of the limiting nut 4-4 is perpendicular to the movable plate 2-2, the connecting plate is L-shaped, one end of the connecting plate is fixedly connected with the limiting nut 4-4, the connecting plate is fixedly connected with the movable frame 9, the limiting bolt 4-3 is fixedly connected with the limiting nut 4-4 through threads, the limiting bolt 4-3 and the limiting nut 4-4 are both located inside the rotating shaft 5, the upper end face of the limiting bolt 4-3 is a first contact face 4-1, and the left end face of the limiting nut 4-4 is a second contact face 4-2.

When the movable plate 2-2 is turned upwards, the movable plate 2-2 and the rotating shaft 5 rotate together along the central axis of the rotating shaft connecting rod 7, the rotating shaft 5 and the rotating shaft bushing 8 rotate relatively, due to the rotation of the movable plate 2-2, the movable frame 9 will also rotate along with the movable plate 2-2, therefore, the limit nut 4-4 and the limit bolt 4-3 rotate simultaneously along with the movable frame 9, when the movable plate 2-2 rotates to the horizontal position, the limiting bolt 4-3 rotates to the vertical position, the upper end surface of the limiting bolt 4-3 just abuts against the first limiting surface 3-1 on the limiting piece 3, due to the limiting effect of the limiting piece 3, the movable plate 2-2 stops moving, so that the movable plate 2-2 and the fixed plate 2-1 are located on the same plane, and the desk plate 2 is convenient to use.
