[0019] By adopting the above technical solution, this solution provides multiple insertion holes on the surface of the lifting rod and the lifting sleeve, and inserts a rod between two of the insertion holes, allowing workers to fix the position of the lifting sleeve and the lifting rod using the rod.

[0020] Optionally, a base is fixedly installed at the bottom of the lifting rod, and three casters are fixedly installed at equal angles at the bottom of the base.

[0021] By adopting the above technical solution, this solution has a base fixedly installed at the bottom of the lifting rod, and three universal wheels fixedly installed at the bottom of the base, so that the housing can be moved by the three universal wheels.

[0022] Optionally, the top of the housing has an opening, and a switch cover is movably hinged to the top of the housing.

[0023] By adopting the above technical solution, this solution has a switch cover that is movably hinged to the top of the housing. When installing the promotional drawings, the staff can open the switch cover to carry out the installation.

[0024] In summary, the present invention has at least one of the following beneficial effects: 1. By setting up a moving mechanism, after the staff inserts the promotional paper into the insert bag, they close the lid and then insert the key into the lock to clamp and fix the promotional paper inside through the limiting plate, thus achieving the effect of fixing the promotional paper. By starting the motor, the motor drives the first and second rotating shafts to rotate, which in turn drives the conveyor belt to rotate. The conveyor belt drives the two insert bags on the surface to switch back and forth for promotion and reading, thereby improving the social effect of educational promotion, attracting the reading interest of viewers, and making it suitable for widespread promotion.

[0025] 2. By incorporating a pressure roller mechanism inside the housing, and a telescopic rod on the rear side of the roller shaft with a return spring fitted on its surface, the roller shaft, under the action of the return spring, presses against the surface of the insert bag, thereby flattening the surface of the promotional image inside the insert bag. This improves the viewing angle of the promotional image and facilitates its selection. Furthermore, by setting up a lifting sleeve and lifting rod, staff can adjust the height of the housing by adjusting their positions. Two support columns facilitate angle adjustment of the housing, thus achieving both height and angle adjustment for easier viewing. Attached Figure Description
