In addition, "plurality" herein refers to two or more, for example, the number of blades 3 shown in FIG. 1 is two.

When the rotating cover 2 rotates relative to the main body 1 , the rotating cover 2 can exert force on each blade 3 , so that each blade 3 slides relative to the rotating cover 2 , and at the same time, the force applied by the rotating cover 2 to each blade 3 also makes each blade 3 relative to the main body 1 By translating, the relative position of each blade 3 and the rotating cover 2 can be changed, so that each blade 3 can be close to or away from the window 21 of the rotating cover 2 . The rotational movement of the rotary cover 2 relative to the main body 1 includes the rotation of the rotary cover 2 relative to the main body 1 in a first direction, and the rotation of the rotary cover 2 relative to the main body 1 in a second direction, wherein the first direction and the second direction are opposite. In addition, when the rotating cover 2 rotates relative to the main body 1, the rotating cover 2 applies force to each blade 3 in the same manner, and the force of the rotating cover 2 causes each blade 3 to translate relative to the main body 1, and make each blade 3 slide relative to the rotating cover 2. The principle is also the same.

When the rotating cover 2 rotates relative to the main body 1 in the first direction, the rotating cover 2 can exert force on the blades 3 to make the blades 3 close to the window 21, and finally can make the blades 3 close the window 21 (as shown in FIG. 4); when rotating When the cover 2 rotates relative to the main body 1 in the second direction, the rotating cover 2 can exert force on the vanes 3 to keep the vanes 3 away from the window 21 and finally enable the vanes 3 to open the window 21 (as shown in FIG. 5 ).
