The worm 21 is located in the middle of the upper end of the counterweight base 1. The outer sides of both ends of the worm 21 are provided with bearing sleeves with brackets 22. The bottom end of the bracket 22 is fixedly connected to the counterweight base 1. The positioning bolt 23 is threadedly installed on the top outer wall of the rear bracket 22. The worm 21 is meshed and connected with the worm wheel 4.

[0028] In this embodiment, by controlling the rotation of the worm 21, the worm wheel 4 can drive the horizontal axis 3 to rotate and adjust, so that the display angle of the advertising board 12 can be adjusted, and the positioning bolt 23 is used to facilitate the positioning of the worm 21.

[0029] On the basis of the above structure, the left and right ends of the movable rod 8 are connected to the mounting seat 7 by bearings, a spiral spring 10 is installed between the movable rod 8 and the mounting seat 7, an advertising board 12 is fixed to the front upper part of the mounting seat 7, and diagonal support rods 13 are fixed to the rear of the left and right ends of the advertising board 12, and the bottom ends of the two diagonal support rods 13 are fixed to the rear upper part of the mounting seat 7.

[0030] In this embodiment, the two diagonal support rods 13 are provided to facilitate supporting the advertisement board 12 , and the advertisement board 12 is used to facilitate pasting of posters and promotional leaflets.

[0031] Based on the above structure, the positioning assembly 9 includes a support spring 91, a square rod 92 and a cylindrical pin 93. Square groove structures are provided inside the left and right ends of the movable rod 8.

[0037] The working principle of the utility model is as follows:

[0038] When in use, first manually rotate the worm 21 to control the worm wheel 4 to drive the horizontal axis 3, the two support rods 5, the mounting seat 7 and the advertising board 12 to rotate, rise and tilt, then tighten the positioning bolts 23 to position the worm 21, and then manually push the mounting seat 7 to move it upward along the support rod 5. Figure 5 As shown in the figure, the support rod 5 can squeeze the inclined part of the cylindrical plug pin 93, so that the cylindrical plug pin 93 and the square rod 92 can be contracted, and the cylindrical plug pin 93 can be separated from the positioning hole 6, which is convenient for the mounting seat 7 to slide upward stably. When the mounting seat 7 moves to a suitable height position, the square rod 92 and the cylindrical plug pin 93 can be extended and reset by the support spring 91, and the cylindrical plug pin 93 can be inserted into another positioning hole 6 opened at an equal distance, so that the mounting seat 7 can be positioned, which is convenient for the stable promotion and exhibition of the advertising board 12. Finally, the promotional posters that need to be promoted and displayed can be pasted on the surface of the advertising board 12 for exhibition;

[0039] After the device is used, the movable rod 8 and the positioning assembly 9 can be rotated 180 degrees by adjusting the handle 11, so that the inclined portion of the cylindrical plug pin 93 faces downward. Similarly, the mounting seat 7 can be controlled to move downward and retract conveniently. Then, the positioning bolt 23 is loosened, and the worm 21 is reversed to control the worm gear 4 to drive the horizontal axis 3, the two support rods 5, the mounting seat 7 and the advertising board 12 to rotate to a horizontal state. Figure 3 In the state shown in , the device can be fully folded, which can effectively reduce the size of the device and make it easier to carry. The device has a simple structure, which is easy to operate and can also reduce the overall weight of the device, making it easier to transfer the device.

[0040] It should be particularly noted that a spiral spring 10 is installed between the movable rod 8 and the mounting seat 7 . After the adjustment handle 11 is released, the movable rod 8 can automatically rotate and reset through the spiral spring 10 .
