[0024] See also Figure 1-Figure 5 In order to facilitate the push-pull operation and ensure the stability of the movement, and to position and fix it during installation to ensure the display effect, a guide groove 8 of a guide component is provided inside the display groove 3, and a guide plate 15 that can slide back and forth in the guide groove 8 is welded at the rear end of the display board 9, and a plug-in column 11 of a plug-in component is welded at the end of one of the display boards 9 (the end close to each other), and a plug-in groove 10 for convenient plug-in of the plug-in column 11 is provided at the corresponding position of the other display board 9, and the main body 2 of the publicity column is located at the through groove 12. A toggle groove 17 of a positioning mechanism is provided on the side wall, and a cylindrical positioning hole 16 is provided in the toggle groove 17, and a sliding cavity 22 of a sliding assembly is provided inside the pull plate 13, and a moving plate 19 is provided in the sliding cavity 22 through a spring 21. The moving plate 19 slides back and forth in the sliding cavity 22, and a sliding rod 20 is welded to the end of the moving plate 19 away from the spring 21. The sliding rod 20 slides out of the sliding cavity 22 and extends to the outside to be welded and fixed to the toggle plate 14, and a positioning column 18 adapted to the positioning hole 16 is welded to the end of the toggle plate 14.

[0025] See also Figure 1-Figure 5 In order to ensure the overall stability, support legs 6 (two or four groups) are welded under the bottom plate 1, and a connecting plate is horizontally welded between the two support legs 6 to ensure the overall stability. Fixed legs 7 are also welded at the bottom of the support legs 6, and the fixed legs 7 can be fixedly connected to the ground by screws, etc., to ensure stability during publicity.

[0026] Working principle: When the utility model is used, the posters to be displayed are pasted on the display board 9, and then the pull plate 13 is pushed to slide the guide plate 15 in the guide groove 8, and the two display boards 9 are close to each other. When they are in contact, the dial plate 14 is toggled to slide the slide bar 20 and the movable plate 19 in the sliding cavity 22. The spring 21 is forced to shrink and store potential energy, and the pull plate 13 is continuously pushed. The dial plate 14 enters the toggle groove 17, and the plug-in column 11 is plugged and positioned with the plug-in groove 10. Then, under the action of the potential energy of the spring 21, the movable plate 19 is reset, and then the positioning column 18 enters the positioning hole 16, completing the display board 9. The display slot 3 is fixed in position, so as not to affect the subsequent publicity display. At the same time, the display slot 3 can be blocked to achieve a sealing effect, which is windproof and prevents dust and water from entering the interior. The top shield 5 can play a role in sunshade and rain shelter during daily use, and can prevent rainwater from entering the interior of the publicity column body 2, so as to avoid getting wet. The supporting legs 6 and fixed feet 7 at the bottom ensure stability during use. When replacement is needed, the positioning column 18 can be moved out of the positioning hole 16 by pressing the dial plate 14, and then the display board 9 can be pulled out by pulling the pull plate 13, so that posters can be easily replaced, and the operation is relatively convenient and safe.
