Driven by the power piece, the L-shaped placement plate 2 is expanded at the bottom end in a rotating manner, and the top ends are slowly fitted together, so that a pair of L-shaped placement plates 2 are relatively tilted, so that the wind resistance will be much smaller and the stability is increased.

[0024] The power part includes a chassis 11; the chassis 11 is configured as a circular shape; a motor 12 is fixedly connected to the inside of the chassis 11; a bidirectional threaded rod 13 is provided at the output end of the motor 12; the top end of the bidirectional threaded rod 13 is rotatably connected to the bottom end of the fixing ring 5; a load-bearing ring 14 is threadedly connected to the bidirectional threaded rod 13; a pair of third grooves 15 are provided on the load-bearing ring 14; a second rotating shaft 16 is rotatably connected in the pair of third grooves 15; a pair of second rotating shafts 16 are rotatably connected to a load-bearing plate 17; the other side of the load-bearing plate 17 is rotatably connected to the connecting shaft 10, when working, by setting a chassis 11 on the base plate 1, and setting a motor 12 in the chassis 11, when the motor 12 drives the bidirectional threaded rod 13 to rotate, it will drive the load-bearing ring 14 threadedly connected to the threaded rod to move upward. Because it is a bidirectional threaded rod 13, it will only move upward to a certain distance and will not move upward. After it moves to a point where a pair of L-shaped placing plates 2 can be pushed to a point close to the top of the L-shaped placing plates 2, it will not move upward. In this way, the L-shaped plate placing plate can be turned into an inclined shape, which increases stability and reduces the wind force received.

[0025] The fasteners include a pair of elastic telescopic rods 18; the pair of elastic telescopic rods 18 are fixedly connected to the top of the L-shaped plate placement plate; the top of the pair of elastic telescopic rods 18 are fixedly connected to a square plate 19. During operation, by arranging the elastic telescopic rods 18 and the square plate 19 on the pair of L-shaped placement plates 2, after the advertising sign board is placed on the L-shaped plate placement plate, the square plate 19 can be pulled to move the elastic telescopic rods 18 upward. After pulling it to the height of the advertising sign board, the advertising sign board is pushed inward to make the advertising sign board fit with the L-shaped plate placement plate. After loosening, the square plate 19 will be stuck to the advertising sign board due to the elastic telescopic rods 18.

[0026] A pair of fourth grooves 20 are provided on the bottom plate 1; a circular plate 21 is slidably connected in the pair of fourth grooves 20; the bottom ends of the pair of circular plates 21 are hollowed out; a vacuum suction cup 22 is provided inside the pair of circular plates 21; a suction cup pull ring 23 is fixed to the top of the circular plate 21; a connecting plate 24 is fixed to the top of the pair of circular plates 21; a transmission member is provided on the bottom plate 1; the transmission member is used to drive the connecting plate 24. During operation, by providing a pair of fourth grooves 20 on the bottom plate 1, the circular plate 21 is driven by the transmission member, and the circular plate 21 can move downward in the fourth groove 20. When the circular plate 21 moves downward and touches the ground, it cannot move downward any further. In this way, the vacuum suction cup 22 provided at the bottom end of the circular plate 21 will touch the ground, and the staff can pull the suction cup pull ring 23 to make the vacuum suction cup 22 adsorb the ceramic floor. This can increase the stability of the device, and can directly place the load and dump it, causing the advertising sign to bump.

[0027] The transmission member includes a support block 25; the support block 25 is threadedly connected to the bidirectional threaded rod 13; the other sides of a pair of connecting plates 24 are fixedly connected to both sides of the support block 25. During operation, the support block 25 is driven to move downward by the bidirectional threaded rod 13. When the support block 25 moves downward, it will drive the connecting plates 24 fixed on both sides to move downward, and then drive the circular plate 21 to contact the ground, so that the vacuum suction cup 22 is adsorbed on the ground.

[0028] A set of universal wheels 26 are fixedly connected to the bottom end of the base plate 1. During operation, by arranging the universal wheels 26 at the bottom end of the base plate 1, the direction of the device can be turned and moved at will when it is needed.

[0029] Working principle: by setting a bottom plate 1, setting a fixing ring 5 above the bottom plate 1, and then setting a pair of support plates 6 on the outer circular wall of the fixing ring 5 to support the L-shaped placement plate 2, so that the L-shaped placement plate can be connected to the first groove 7 by rotating the square column 4 on the opposite side, and then driven by the power part, the L-shaped placement plate 2 is expanded at the bottom end by rotating, and the top end is slowly fitted together, so that the pair of L-shaped placement plates 2 are relatively tilted, so that the wind resistance will be much smaller and the stability is increased. By setting a chassis 11 on the bottom plate 1 and setting a motor 12 in the chassis 11, when When the motor 12 drives the bidirectional threaded rod 13 to rotate, it will drive the load-bearing ring 14 threadedly connected to the threaded rod to move upward. Because it is a bidirectional threaded rod 13, it will only move upward to a certain distance and will not move upward. When it moves to a point where a pair of L-shaped placement plates 2 can be pushed to a point close to the top of the L-shaped placement plate 2, it will not move upward. In this way, the L-shaped plate placement plate can be turned into an inclined shape. The inclined shape increases stability and reduces the wind force received. By arranging elastic telescopic rods 18 and square plates 19 on a pair of L-shaped placement plates 2, the advertising signboard can be placed on the L-shaped plate. After placing it on the board, pull the square board 19 to move the elastic telescopic rod 18 upward. After pulling it to the height of the advertising signboard, push the advertising signboard inward so that the advertising signboard fits the L-shaped board placement board. After loosening, the square board 19 will be stuck to the advertising signboard due to the elastic telescopic rod 18. By opening a pair of fourth grooves 20 on the bottom plate 1, the circular plate 21 can be driven by the transmission member so that the circular plate 21 can move downward in the fourth grooves 20. When it moves downward and touches the ground, it cannot move downward anymore. In this way, the vacuum suction cup 22 at the bottom end of the circular plate 21 is It will touch the ground, and the staff can pull the suction cup pull ring 23 to make the vacuum suction cup 22 adsorb the ground ceramic floor, which can increase the stability of the device and can directly place the load and dump it to make the advertising logo bump into it. The support block 25 is driven by the two-way threaded rod 13 to move downward. When the support block 25 moves downward, it will drive the connecting plate 24 connected on both sides to move downward, and then drive the circular plate 21 to contact the ground, so that the vacuum suction cup 22 is adsorbed on the ground. By arranging a universal wheel 26 at the bottom end of the base plate 1, the direction of the device can be turned and moved at will when it is needed.
