[0028] An adjustment mechanism for adjusting the rotation angle of the vertical connecting column 7 is provided on the outer side of the sector plate 6;

[0029] A descending mechanism for descending the vertical insertion rod 17 is provided inside the vertical lifting column 10;

[0030] The adjustment mechanism includes a longitudinal connecting shaft 8, a longitudinal connecting shaft 8 is fixed inside the top of the vertical connecting column 7, the longitudinal connecting shaft 8 passes through the interior of the fan-shaped plate 6 and is rotatably connected to the fan-shaped plate 6 through a bearing, the longitudinal connecting shaft 8 is close to one end of the U-shaped shelf 1 and is rotatably connected to the U-shaped shelf 1 through a bearing, a first longitudinal limiting rod 11 is slidably connected inside the vertical connecting column 7 and at the bottom of the longitudinal connecting shaft 8, a first circular pull block 13 is fixed to one end of the first longitudinal limiting rod 11, and a first rigid spring 12 is provided between the vertical connecting column 7 and the first circular pull block 13 and on the outside of the first longitudinal limiting rod 11;

[0031] A plurality of circular through holes are provided inside the sector plate 6, and the first longitudinal limiting rod 11 is matched with the circular through holes so that the first longitudinal limiting rod 11 can enter the sector plate 6, thereby limiting the rotation of the vertical connecting column 7 outside the sector plate 6;

[0032] Here, it is necessary to rotate the vertical connecting column 7. At this time, the first rigid spring 12 is stretched under force, and the first rigid spring 12 is pulled in the direction away from the fan-shaped plate 6. The pulling of the first rigid spring 12 enables the first longitudinal limiting rod 11 to slide inside the vertical connecting column 7, thereby enabling the first longitudinal limiting rod 11 to move out of the fan-shaped plate 6, and then the angle of the vertical connecting column 7 is adjusted. When the vertical connecting column 7 is rotated to the corresponding angle, the pulling of the first circular pull block 13 can be released. The elastic characteristics of the first rigid spring 12 enable the first longitudinal limiting rod 11 to enter the fan-shaped plate 6, thereby limiting the rotation of the vertical connecting column 7.

[0033] The outer side of the vertical cylinder 9 is threadedly connected with a circular rotating member 14, and a T-shaped rotating ring 22 is fixed on the top of the vertical lifting column 10. The inside of the T-shaped rotating ring 22 is located inside the circular rotating member 14 and is rotatably connected to the circular rotating member 14 through a bearing. Through the arrangement of the T-shaped rotating ring 22 and the bearing, the circular rotating member 14 can rotate on the top of the vertical lifting column 10;

[0034] An internal thread groove is provided on the outer side of the vertical cylinder 9, and an external thread groove is provided on the inner side of the circular rotating member 14. The vertical cylinder 9 and the circular rotating member 14 are threadedly connected by the matching internal thread groove and the external thread groove. The matching of the internal thread groove and the external thread groove enables the vertical cylinder 9 and the circular rotating member 14 to be threadedly connected.

[0035] Both ends of the vertical lifting column 10 are provided with vertical sliders, and the outer side of the vertical cylinder 9 is provided with a vertical slide groove adapted to the vertical slider. The vertical cylinder 9 and the vertical lifting column 10 are slidably connected through the cooperation of the vertical slider and the vertical slide groove. Through the cooperation of the vertical slide groove and the vertical slider, the vertical lifting column 10 can slide vertically on the outer side of the vertical cylinder 9.

[0036] Here, the circular rotating member 14 is rotated, and the rotation of the circular rotating member 14 enables the vertical lifting column 10 to slide vertically on the outside of the vertical cylinder 9. The sliding of the vertical lifting column 10 enables the bottom support seat 5 to be vertically lifted and lowered, thereby enabling the bottom support seat 5 to better fit the ground, so that after the square billboard 2 is rotated to a certain angle, the bottom support seat 5 can contact the ground and support the U-shaped shelf 1;

[0037] The descending mechanism includes a vertical lifting block 16, the vertical lifting block 16 is slidably connected to the bottom of the vertical lifting column 10, the bottom of the vertical lifting block 16 is fixedly connected to the vertical plug rod 17, the top of the vertical lifting block 16 and the second rigid spring 18 is arranged inside the vertical lifting column 10, the outer side of the vertical lifting column 10 is sleeved with a U-shaped support frame 15, the inner side of the U-shaped support frame 15 is slidably connected to a second longitudinal limiting rod 19, one end of the second longitudinal limiting rod 19 is fixed with a second circular pull block 20, the outer side of the second longitudinal limiting rod 19 is fixed with a circular fixing block 23, and a third rigid spring 21 is arranged between the circular fixing block 23 and the U-shaped support frame 15;

[0038] The second longitudinal limiting rod 19 passes through the interior of the vertical lifting column 10 and is slidably connected to the vertical lifting column 10. A circular limiting hole adapted to the second longitudinal limiting rod 19 is provided inside the vertical lifting block 16, so that after the second longitudinal limiting rod 19 enters the interior of the vertical lifting block 16, the second longitudinal limiting rod 19 can limit the sliding of the vertical lifting block 16 inside the vertical lifting column 10;

[0039] A vertical circular groove is provided inside the vertical lifting column 10, and a vertical lifting block 16 is located inside the vertical circular groove and is slidably connected to the vertical circular groove, and a second rigid spring 18 is located inside the vertical circular groove. Through the setting of the vertical circular groove, the vertical lifting block 16 can slide vertically inside the vertical lifting column 10. A vertical through hole adapted to the vertical insertion rod 17 is also provided inside the bottom end of the vertical lifting column 10. Through the setting of the vertical through hole, the vertical insertion rod 17 can move out of the interior of the vertical lifting column 10.

[0040] Here, when the vertical insertion rod 17 is located inside the vertical lifting column 10, the second rigid spring 18 is in a stressed contracted state, pulling the second circular pull block 20 in a direction away from the vertical lifting column 10. The pulling of the second circular pull block 20 enables the second longitudinal limiting rod 19 to move out of the vertical lifting block 16, so that the circular fixed block 23 can move. When the circular fixed block 23 moves, the third rigid spring 21 is stressed and contracted. When the second longitudinal limiting rod 19 moves out of the vertical lifting block 16, the elastic characteristics of the second rigid spring 18 enable the vertical insertion rod 17 to be inserted into the ground, thereby improving the wind resistance.

[0041] Working principle: the vertical connecting column 7 needs to be rotated, at which time the first rigid spring 12 is stretched under force, and the first rigid spring 12 is pulled in the direction away from the fan-shaped plate 6. The pulling of the first rigid spring 12 enables the first longitudinal limiting rod 11 to slide inside the vertical connecting column 7, thereby enabling the first longitudinal limiting rod 11 to move out of the fan-shaped plate 6, and then the angle of the vertical connecting column 7 is adjusted. When the vertical connecting column 7 is rotated to the corresponding angle, the pulling on the first circular pull block 13 can be released. The elastic characteristics of the first rigid spring 12 enable the first longitudinal limiting rod 11 to enter the fan-shaped plate 6, thereby limiting the rotation of the vertical connecting column 7.

[0042] The circular rotating member 14 is rotated, and the rotation of the circular rotating member 14 enables the vertical lifting column 10 to slide vertically on the outside of the vertical cylinder 9. The sliding of the vertical lifting column 10 enables the bottom support seat 5 to be vertically lifted and lowered, thereby enabling the bottom support seat 5 to better fit the ground, so that after the square billboard 2 is rotated to a certain angle, the bottom support seat 5 can contact the hard ground and support the U-shaped shelf 1;

[0043] When the installation location is on the ground, after the vertical insertion rod 17 is located inside the vertical lifting column 10, the second rigid spring 18 is in a stressed contracted state, pulling the second circular pull block 20 in a direction away from the vertical lifting column 10. The pulling of the second circular pull block 20 enables the second longitudinal limiting rod 19 to move out of the interior of the vertical lifting block 16, so that the circular fixed block 23 can move. When the circular fixed block 23 moves, the third rigid spring 21 is stressed and contracted. When the second longitudinal limiting rod 19 moves out of the interior of the vertical lifting block 16, the elastic characteristics of the second rigid spring 18 enable the vertical insertion rod 17 to be inserted into the ground, thereby improving the wind resistance.
