Air conditioner-wind deflector limit

When I sleep at night, the wind deflector of the air conditioner always can't turn to the angle I want, so I designed a limit to limit the angle of the wind deflector so that the wind doesn't blow down and doesn't blow to myself. This limit is suitable for use on Panasonic air conditioners, like I posted in the picture. You only need to install it in the right place with a 1-2mm 3M tape.
