Description of the Invention: [Technical Field to Which the Invention Is Applicable] The present invention relates to a fan fixing device, particularly a fan fixing device used in an electronic device housing. [Prior Art] [0002] The main heat source in the personal computer system is the central processing unit and the computer case on the motherboard _ The power supply H is turned by the central processor to install the heat sink to the central processor The heat generated is discharged. In addition, the power supply (4) has a fan to discharge the amount it produces. With the continuous development of the computer industry, the power of the internal components of the electric service (such as the increase in the central processing (four) rate) and the increase in heating elements have given rise to new problems. Therefore, in order to achieve a better heat dissipation effect, it is necessary to install a fan that runs independently in the computer casing, thereby discharging the heat in the computer casing, and cooperating with the fan of the power supply device to generate convection in the computer casing to lower the computer. The internal temperature of the housing. Usually, the fan is directly fixed to the rear panel of the computer case by screws, and then assembled or disassembled.

At this time, the first plate 45 of the fan 4 is located at the limit of the rear plate 10. On the block 16, then the fan 40 is moved on the rear plate 1 ,, so that the connecting portion 47 of the latch 47 slides from the through hole 151 of the fixing hole 15 to the first plate 45 of the fan 40 in the limiting slot 153. The limiting block 16 and the limiting block ^ resist the edge of the first plate 45 to block the fan 40 from sliding back, and the locking portion 472 of the locking 47 is locked with the rear plate 1 to fix the fan 4 to The rear panel 1 is here, where the fan 40 is opposite the venting zone 12 of the rear panel 10. When it is necessary to remove the fan 4 from the rear panel 10, the fan 40 is pulled away from the rear panel 1 to lift the first panel 45 without colliding with the limiting block μ, and then the fan 40 is moved. The connecting portion 4 71 of the latch 47 is slid into the through hole 151 from the limiting slot 153, and the fan 40 can be detached from the rear plate 10. The lock 47 of the fan fixing device is integrally formed on the fan 4, thereby avoiding the use of an additional fixing means for fixing the fan 40.
