It can be understood that the front end of the limiting seat 710 is provided with a first engaging projection in an arc shape, the rear end of the limiting block 720 is provided with a second engaging projection in an arc shape, and the first engaging projection and the second engaging projection are arranged in opposite directions. When the fan body 300 closes the frame body 100, the rear end of the first engaging projection abuts against the front end of the second engaging projection, thereby playing a role of prying resistance. When the fan body 300 opens the frame body 100, the fan body 300 rotates along the surface radians of the first engagement protrusion and the second engagement protrusion, so that the first engagement protrusion and the second engagement protrusion can rotate relative to each other, and the fan body 300 and the frame body 100 can be unlocked.

The above is only the preferred embodiment of the present invention, not so limiting the patent scope of the present invention, all of which are in the utility model discloses a conceive, utilize the equivalent structure transform that the content of the specification and the attached drawings did, or directly/indirectly use all to include in other relevant technical fields the patent protection scope of the present invention.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
