[Prior Art] Blocking high-power electronic 70 devices such as computer central processing unit, north bridge chip, graphics card, etc. will generate a large amount of heat during operation. If this heat cannot be effectively dissipated, it will directly cause the temperature to rise sharply and seriously Affects the normal operation of the electronic 70 device. For this reason, a heat sink is required to dissipate the electronic components, and a fastening device is also required to fix the heat sink to the electronic components. Japanese Patent No. 0m5323.0 discloses a heat sink assembly σ comprising a heat sink and an alpha component for fixing the heat sink to the electronic component. The heat dissipation benefit includes a base and a plurality of cylindrical pieces extending upward from the base. The fastening element is - the metal rod is integrally bent = into 'with a ring and two respectively extending backward from both ends of the ring. When the heat sink is used on the electronic component, it is only necessary to pass the ring of the buckled part through one of the heat sinks to the one piece, and then the two parts of the fastening component. The sub-U ^ is on the circuit board, and the assembly can be completed. However, the buckle can only limit the heat sink, and the ', ' and the cymbals produce a lateral pressing force. After the fins of the radiator are fastened, the fastening components will be thinner if the fins of the radiator are thin, and the pressure of the extruded fuse will easily cause the fins to deform, causing the ring of the fastening component to fall off the fins. As a result, the fastening element cannot fix the heat sink. As a result, the contact between the heat sink and the electronic components is extremely unstable and is greatly affected by the shape of the fins. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a combination of fastening devices that can stably fix a heat sink to an electronic component.

Compared with the prior art, the base of the fastening device combination of the present invention is combined with the heat sink to fix the heat sink to the base of the fastening device combination; and then, the two fastening components are respectively located on both sides of the heat sink. Directly acting on the pedestal, the heat sink can be attached to the electronic component without the need to cooperate with the heat sink. Therefore, no matter how the structure of the heat sink changes, it will not affect the two fastening components, so that stable contact between the heat sink and the electronic components can be achieved.
