When the power generating device 3 is used, the power generating device 3 is arranged inside the shell 2, the shell 2 plays a role in protecting the power generating device 3, when fluid such as airflow, water flow and the like impacts the power capturing device 1, the rotating shaft 3-1-2 moves along with the power capturing device 1 through the transmission connection relation with the power capturing device 1, and at the moment, the first moving component 3-1-1 and the second moving component 3-1-3 which are arranged along the axial lead direction and fixedly arranged on the rotating shaft 3-1-2 rotate along with the rotating shaft 3-1-2 around the axial lead.
