A throughhole 621 is axially defined in thefirst fastener 60, through thehead 64, thepole 62, and thefixing portion 68. The outside diameter of thefixing portion 68 is the same as thepole 62. The inside diameter of thefixing portion 68 becomes less from a first portion of thefixing portion 68 adjacent to thepole 62 to a second portion of thefixing portion 68 away from thepole 62, which forms an acute angle a between extension lines of the inner surface and the outer surface of thefixing portion 68 along the axis direction of thefirst fastener 60. An annular andtapered block 682 is formed on an inner surface of thefixing portion 68. A plurality ofsplits 684 is defined in thefixing portion 68, parallel to the axis direction of thefirst fastener 60. Thefirst fasteners 60 are made of resilient material, such as plastic or metal. - Each
second fastener 70 includes ashaft 72 and ahead 74 formed at one end of theshaft 72. Anannular receiving portion 742 is defined in thehead 74, around theshaft 72, as shown inFIG. 5 .

FIG. 4 andFIG. 5 , in assembly, theshockproof members 50 are inserted into thecorresponding locking holes 222 from thelarge portions 223. Theshockproof members 50 are then pushed to thesmall portions 224. Therefore theshockproof members 50 are locked in thelocking holes 222 through the wall bounding thesmall portions 224 engaging in thelocking slots 52. Theside plate 42 is in close contact with theshockproof members 50, with the blades of thefan 40 aligning with thevent 221. Themounting holes 422 align with the corresponding throughholes 51. Thepole 62 extends through the corresponding throughhole 51 and thecorresponding mounting hole 422. Thefixing portion 68 extends out of themounting hole 422 and is positioned at an inside of theside plate 42. Acorresponding shaft 72 is inserted into thethrough hole 621, until thehead 64 is received in thereceiving portion 742. Theshaft 72 presses theblock 682 to deform thefixing portion 68 out to form astop portion 686 protruding on the outer surface of thefixing portion 68, which forms an acute angle β (approximately same as the acute angle α) between extension lines of the inner surface and the outer surface of thefixing portion 68 along the axis direction of thefirst fastener 60. Thestop portion 686 resists against the inner side of theside plate 42 to avoid thefirst fastener 60 releasing from themounting hole 422. Theshockproof members 50 are positioned between theside plate 42 and thebase wall 22. Thesplits 684 are used to add elasticity of thefixing portion 68 to be easily deformed. - In disassembly, the
shafts 72 are pulled from the throughholes 621. Thefixing portions 68 are restored to make thefirst fasteners 60 be easily released from themounting holes 422. - In another embodiment, the
shockproof members 50 are unnecessary. Thebase wall 22 defines four through holes to allow thefirst fasteners 60 extending through. - The fan module in this embodiment utilizes four
first fasteners 60 and four correspondingsecond fasteners 70 to mount thefan 40 to thebracket 20, which is convenient. Theshockproof members 50 can absorb the shock of thefan 40. - Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
