In the original structure, a single-layer slot structure is adopted and the original end cover is made of iron material. The end cover is clamped on the louver by embedding the single-layer slot into the gap of the step rivet.

[0004] The surface of the step rivets and end covers will be covered with plastic powder to achieve the effect of rust prevention and aesthetics. However, in the actual installation process, due to the uneven thickness of the plastic spraying, during the matching process of the step rivets and the end covers, the plastic powder on the step rivets and the end covers will fall off, losing the anti-rust function and greatly increasing the time of rust.

[0005] At the same time, the original end cover uses riveting to install the rotating shaft on the end cover, but in the actual survival process, some rotating shafts cannot be completely fastened to the end cover, which will cause the rotating shaft to rotate on the end cover, and the rotating shaft cannot drive the rotation of the end cover when rotating.
