[0032] When the first motor 5 operates, the lead screw 6 will start to rotate. At this time, the moving plate 7 will start to move to the left under the drive of the lead screw 6, and the connecting rod 8 will start to rotate under the drive of the moving plate 7. During this process, the other end of the connecting rod 8 will drive the connecting block 9, so that the connecting block 9 and the lighting lamp housing 2 as a whole start to move in the direction of the inside of the storage box 1.

[0045] The working principle and usage process of the present utility model:

[0046] First, the operator places the entire storage box 1 above the blackboard, and then starts the second motor 14. As the second motor 14 operates, the round shaft 15 and the gear 16 will start to rotate. Since the gear 16 and the toothed plate 17 are meshed with each other, the two toothed plates 17 as a whole will move towards each other along the inner surface of the hollow plate 12 driven by the gear 16.

Finally, when the two clamping plates 19 contact the left and right sides of the blackboard, the two clamping plates 19 will clamp the blackboard, so that the entire storage box 1 is fixed above the blackboard.

[0047] When the operator needs to illuminate the blackboard, the operator starts the first motor 5. As the first motor 5 operates, the lead screw 6 will start to rotate, and the rotation of the lead screw 6 will drive the moving plate 7, causing the moving plate 7 to start moving to the right under the limitation of the limiting block 11. During the movement of the moving plate 7, the connecting rod 8 will start to rotate with the front end of the moving plate 7 as the axis, and the other end of the connecting rod 8 will drive the connecting block 9, causing the connecting block 9 and the entire lighting lamp housing 2 to start moving towards the outside of the storage box 1. Finally, the entire lighting lamp housing 2 protrudes from the inside of the storage box 1, so that the LED lamp 22 can evenly illuminate the blackboard.

[0048] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
