Fan

Abstract

A fan includes a main body and a clip. The main body includes a board defining a through hole. The clip includes a base wall and two end walls extending down from opposite ends of the base wall. A pair of claws extends from one of the end walls away from the other end wall. Each claw includes an engaging portion. The engaging portions is operable to be deformed toward each other to pass through the through hole, thereby sandwiching the board with the corresponding end wall.

What is claimed is: 
     
         1 . A fan comprising:
 a main body comprising a board defining a through hole; and   a clip comprising a base wall and two end walls extending down from opposite ends of the base wall, a pair of claws extending from one of the end walls away from the other end wall, each claw comprising an engaging portion, the engaging portions operable to be deformed toward each other to pass through the through hole, thereby sandwiching the board with the corresponding end wall.   
     
     
         2 . The fan of  claim 1 , wherein each claw further comprises a semi-cylindrical protrusion perpendicularly extending from the corresponding end wall, each engaging portion is formed on a distal end of the corresponding protrusion away from the end wall. 
     
     
         3 . The fan of  claim 2 , wherein the engaging portion is tapered.
