A protective frame is fixedly installed on the top of the transverse support plate. A rotating motor is fixedly installed on one inner wall of the protective frame. A rotating rod is fixedly installed on the output shaft of the rotating motor. The rotating rod penetrates through the transverse support plate and is rotatably connected with the transverse support plate. An adapter frame is arranged inside the internal funnel.
