one end of the solar or lunar halo has described flanging, the flanging and ontology The edge of the ventilation hole is fixedly connected. The air shield of the utility model is changed from the original integral structure into a split structure,
and the body and the air shield are processed separately, so as to reduce the processing difficulty and processing cost on the one hand, and on the other hand, it does not need the overall molding mold,
and can be adapted to the production of small batch and multiple specifications.
