Problems solved by technology

Its defect is: after the baffle slides up and down, the fixation is mostly done by screws, that is, the baffle can slide up and down after the screws are loosened, and the baffle can be fixed after the screws are tightened
Obviously, such an operation is cumbersome, and it is very easy for the screws to loosen by themselves and not be stable enough so that the baffle cannot form a seal on the opening
