Each connecting portion 140 is provided with a through hole 1400 corresponding to the fixing hole 120 of the body 12 near the two ends. The fixing member 80 is sequentially passed through the through hole 1400 and the fixing hole 120 to fix the fixing frame 10 on the base 30. The catch portion 142 is a sheet body having a pair of hump-shaped free ends and an arc-shaped edge at the two free ends. The inner side of each of the free ends is convexly disposed on one of the bumps 1420 of the fan 20, and a recess 1422 is formed on the outer side of the free end 140 of the bump 1420. The recess 1422 corresponds to the connecting portion 140. Perforation 1400 settings. The holding portion 142 is perpendicular to the main body 12 and is disposed at a distance from the main body 12 so that the fixing portion 80 of the main body 12 of the fixing frame 10 is fixed to the base 30, and the engaging portion 142 and the connecting portion 140 are simultaneously fixed. The member 80 is in close proximity to the body 12 of the holder 10 and the surface of the fan 20 so as to clamp the fan 20 between the two parallel holding portions 142 of the two side arms 14. The pair of clamping portions 18 are vertically disposed at the edges of the opposite short sides of the body 12, and the clamping portion 18 is located between the two opposite short sides of the body 12 and the two holding portions 142 of the side arms 14. The clamping portion 18 has a rectangular sheet body, and two opposite sides of each of the clamping portions 18 extend horizontally inwardly to form a pair of baffles 180 which are parallel to each other and perpendicular to the body 12. The baffle 180 is located between the two side arms 14. Each of the baffles 180 has a substantially triangular shape, and its height gradually decreases along the long side of the body 12 toward the center of the center 9 201002190, so as to facilitate insertion into the fan 20 to cooperate with it. The fan 20 is generally square in shape and includes two left and right flat plates (not labeled) with openings. A four-corner edge of each of the flat plates extends horizontally outwardly from a lug 22, and a central portion of the lug 22 is provided with a buckle hole 220 for engaging the bump 1420 of the retaining portion 142 of the fixing frame 10 to fix the fan 20 to the fixing member. 10 on.
