[0037] The working principle of the technical solution provided by the present invention is as follows: when in use, first place the bottom bar 2 at the front end of the desk, then pull the adjustment structure according to the length of the desk, pull the moving rod 10 out from the inside of the bottom bar 2, and the moving rod 10 slides out of the bottom bar 2 horizontally. During the sliding process, the moving rod 10 drives the driving rod 22 to move synchronously, and the tooth block 9 on the driving rod 22 cooperates with the gear plate 7, and the gear plate 7 rotates under force. Since the driving rod 22 is symmetrically arranged on both sides of the gear plate 7, it is only necessary to pull the moving rod 10 on one side of the bottom bar 2, and the moving rods 10 on both sides extend synchronously until the length of the desk is adapted, and then the side wall of the desk is placed between the clamping block 12 and the fixed block 19, and then the adjusting screw 14 is rotated, and the adjusting screw 14 rotates to drive the lifting block 16 to move, and the lifting block 16 drives the connecting block 17 to move synchronously, and then the clamping block 12 approaches the fixed block 19 to clamp the side wall of the desk;

[0038] After the clamping is completed, the lighting panel 3 can be fixed on the desk. According to the lighting needs, the lighting panel 3 can be adjusted to any position. The lighting top plate is pushed, and the bottom slider 27 at the bottom of the supporting vertical plate 26 slides under force. The bottom slider 27 moves along the outside of the supporting slide bar 5. The lighting panel 3 can be adjusted laterally. The lighting panel 3 is rotatably connected to the fixed block 19 and can be flipped and swung. A damping mechanism is provided at the rotating connection, and the lighting panel 3 can be rotated and adjusted to any position.

[0039] When it is necessary to lift the lighting panel 3, the limit rod 23 is pulled, and the limit rod 23 withdraws from the inside of the limit socket 25, so that the driving rod 22 can be lifted, and the driving rod 22 drives the lifting plate 21 to be lifted synchronously, and the inner slide plate 20 at the bottom of the lifting plate 21 is lifted synchronously. After the inner slide plate 20 slides out along the supporting vertical plate 26, the lighting panel 3 can be raised to a higher position. When the limit rod 23 is flush with the limit socket 25 at the corresponding position, the pull on the limit rod 23 can be released, and the spring 28 is reset to push the moving block 29 in the direction away from the limit block 30, thereby driving the limit rod 23 to slide into the limit socket 25 at the corresponding position, completing the limiting of the driving rod 22. After the driving rod 22 cannot move, the lighting panel 3 stays at the required height.
