[0050] During use, the staff move the promotional device to a suitable position through two sets of universal wheels 2, and then start the second motor 561. The second motor 561 drives the fifth bevel gear 562 to rotate. The fifth bevel gear 562 drives the third lead screw 54 to rotate through the sixth bevel gear 563. The third lead screw 54 drives the universal wheel 2 at the bottom of the round rod 55 to move towards the inside of the storage hole 512 through the long plate 53, and the universal wheel 2 is stored through the storage hole 512. At the same time, the base 51 contacts the ground, increasing the contact area between the promotional device and the ground, and avoiding the situation that the promotional device is prone to tipping when subjected to a little external force interference. This not only does not damage the promotional device but also plays a role in publicity. Then start the first motor 33. The first motor 33 rotates forward to drive the first lead screw 34 to rotate. The first lead screw 34 drives the display board 1 to move upward. At the same time, the first lead screw 34 drives the second bevel gear 383 to rotate through the first bevel gear 381. The second bevel gear 383 drives the third bevel gear 384 to rotate through the rotating shaft 382. The third bevel gear 384 drives the second lead screw 36 to rotate through the fourth bevel gear 385. The second lead screw 36 drives the universal wheel 2 below to move downward along the guiding hole 314 through the square block 37, and extends out of the protective box 31 through the display board 1 and the square block 37. When the display board 1 is fully extended, the display board 1 is used for publicity. When it is necessary to transport the promotional device, the first motor 33 rotates reversely and cooperates with the corresponding structure to drive the display board 1 and the square block 37 to contract towards the inside of the protective box 31. The protective box 31 protects the display board 1 and also reduces the space occupied by the promotional device. This is not only convenient for transportation but also reduces the transportation cost, with high economic benefits. When dust accumulates on the display board 1, the display board 1 moves towards the inside of the protective box 31, and the cleaning brush 42 on the annular plate 41 cleans the display board 1 that contracts towards the inside of the protective box 31. There is no need for personnel to wipe it frequently, which not only saves human resources but also meets people's needs. When the cleaning brush 42 is worn or damaged, the staff pull the pull plate 435. The pull plate 435 drives the insertion pin shaft 433 to disengage from the pin hole 434 on the annular plate 41. At the same time, the stepped plate 436 on the insertion pin shaft 433 presses the spring 437, causing the spring 437 to generate tension. The tension of the spring 437 can drive the insertion pin shaft 433 back to the initial position. By disengaging the insertion pin shaft 433 from the pin hole 434, it is convenient to disassemble the annular plate 41, and thus it is also convenient to disassemble and replace the worn cleaning brush 42.
