Holding pole structure for blocking net and holding pole combined net blocking method

According to the derrick structure for blocking the net and the derrick combination net blocking method, derricks are divided into an arm-free derrick and a rocker arm derrick, rocker arms are installed on the two sides of the top of the rocker arm derrick through bent arm mechanisms, and locking mechanisms used for connecting and fixing the adjacent derricks and net pulling mechanisms used for connecting net ropes are installed on the rocker arms; a spanned object is spanned through the rocker arms, then the locking mechanisms are used for being fixed to the adjacent holding poles, then net pulling operation is carried out through the pulling nets, a stable frame body can be built, cooperation of an unmanned aerial vehicle is not needed, net pulling can be conveniently carried out, and construction convenience and working efficiency are effectively improved; the high-altitude operation requirement can be reduced; and the working safety is improved. 一种封网用抱杆结构及抱杆组合封网方法，抱杆分为无臂抱杆和摇臂抱杆，摇臂抱杆的顶部两侧通过弯臂机构安装有摇臂，各摇臂上安装
