[0029] When in use, the hanging ring 15 is fixed to the hook installed under the drone. After the drone takes off, the pulling device is suspended in the air. The counterweight 32 located under the fixing rod 11 balances the weight on both sides of the upper load-bearing wire 14 to ensure the balance of the flag structure 2.

[0030] The first fixing hole 22 corresponds to the first fixing ring 12, and the lower part of the first fixing ring 12 passes through the corresponding first fixing hole 22 to achieve fixed connection between the fixing structure 1 and the flag structure 2. The second fixing hole 23 corresponds to the second fixing ring 332, and the second fixing ring 332 passes through the corresponding second fixing hole 23 to achieve fixation between the flag structure 2 and the counterweight structure 3.

[0031] The first fixing ring 12 and the second fixing ring 332 are used to limit the upper part and one side of the flag body 21 to prevent the flag body 21 from bending or turning over due to airflow in the air;

[0032] At the same time, the limiters 331 located on the upper and lower sides of each set of second fixing rings 332 can well ensure that the second fixing rings 332 are not displaced by wind, thereby enhancing overall safety.
