An adjusting rod 33 is provided at the other end of the horizontal rod 32. A lighting lamp 34 is provided at the other end of the adjusting rod 33. A rotating shaft passes through the connection between the vertical rod 31 and the horizontal rod 32. A rotating shaft passes through the connection between the horizontal rod 32 and the adjusting rod 33. The connection between the adjusting rod 33 and the lighting lamp 34 is connected by a rotating connector.

[0028] When in use, the auxiliary lighting mechanism is combined with the electric telescopic rod. The height of the equipment can be adjusted to suit the user's height by raising and lowering the electric telescopic rod. At the same time, the horizontal bar, vertical bar and adjustment rod are rotated and tilted to adjust the lighting angle, making the light more comfortable for the user when writing.

[0029] The fixing mechanism 8 includes a groove 81 and a spring 82. The spring 82 is arranged inside the groove 81. A snap-fit ​​protrusion 83 is arranged at the other end of the spring 82. A snap-fit ​​groove 84 is arranged on one side of the snap-fit ​​protrusion 83. By aligning the snap-fit ​​protrusion 83 with the snap-fit ​​groove 84, the spring 82 loses its resistance and pushes the snap-fit ​​protrusion 83 into the inside of the snap-fit ​​groove 84, thereby fixing the left writing board 6 and the right writing board 7.

[0030] A controller 9 is provided on the front side surface of the base plate 4, and electric telescopic rods 10 are symmetrically provided on the bottom end surface of the base plate 4. Support frames 11 are provided on the bottom end surfaces of the electric telescopic rods 10, and stabilizing rods 12 are provided on the opposite surfaces of the support frames 11.

[0031] Grid lines are arranged on the front surface of the illuminated glass light box 1, the left writing board 6 and the right writing board 7 have the same structure, and the left writing board 6 and the right writing board 7 are arranged symmetrically in a mirror image, and hidden handles are arranged on the back surfaces of the left writing board 6 and the right writing board 7. The bottom plate 4 and the top plate 2 are the same size, and the combined shape of the support frame 11 and the stabilizing rod 12 is an I-shape; through the auxiliary grid lines of the illuminated glass light box 1, the size can be quickly seen using the grid lines, thereby improving the efficiency of teaching demonstrations.

[0032] The other end of the vertical rod 31 is fixedly connected to the top plate 2 , and the length of the horizontal rod 32 is greater than the width of the top plate 2 ; the vertical rod 31 cooperates with the horizontal rod 32 to allow the lighting lamp 34 to be adjusted in angle.

[0033] The groove 81 is set on the right side surface of the left writing board 6 and the left side surface of the right writing board 7, and the clamping protrusion 83 passes through the top surface and bottom surface of the left writing board 6 and the right writing board 7, and the left writing board 6 and the right writing board 7 are positioned and fixed by the clamping protrusion 83.

[0034] Working principle: the controller 9 controls the lighting 34 and the electric telescopic rod 10. The controller 9 is a PLC controller, and the model of the controller 9 can be S7-200. Before use, power on the device to ensure that the device can be used normally. When preparing, place the device in a suitable teaching position, control the electric telescopic rod 10 to move up and down, thereby driving the bottom plate 4 to move up and down, so that the height of the device is adjusted to a suitable height for teaching use, and then flip the cross bar 32 and the adjustment rod 33 to adjust the distance and height of the lighting 34, so as to better illuminate the left writing board 6 and the right writing board 7 for writing and demonstration. When using, hold the hidden handles on the back of the left writing board 6 and the right writing board 7 respectively, so as to move the left writing board 6 and the right writing board 7. The writing board 7 moves outward along the slide groove 5 until the snap-on protrusion 83 is aligned with the snap-on groove 84, so that the spring 82 loses resistance and pushes the snap-on protrusion 83 into the inside of the snap-on groove 84, thereby fixing the left writing board 6 and the right writing board 7, and at the same time, the auxiliary grid lines of the lighting glass light box 1 can be used, and the dimensions can be quickly seen using the grid lines, thereby improving the efficiency of teaching demonstrations; when the lighting glass light box 1 needs to be used alone, the snap-on protrusion 83 on one side of the left writing board 6 and the right writing board 7 is pressed, so that the snap-on protrusion 83 shrinks to the left writing board 6 and the right writing board 7, and the spring 82 shrinks at the same time, so that the left writing board 6 and the right writing board 7 can be slid along the slide groove 5 to the back side of the lighting glass light box 1, so that the lighting glass light box 1 can be used alone.
