Description of the Invention: [Technical Field] The present invention relates to a fastening device, and more particularly to a fastening device for fixing a heat sink to a heat-generating electronic component. [Prior Art] According to the continuous development of the electronics industry, the electronic components inside the computer generate a large amount of heat during operation. If the heat accumulates in the electronic components, it will affect the running performance of the electronic components. To ensure the normal operation of the electronic components, The heat needs to be dissipated from the electronic components in time. The industry usually provides a heat dissipation structure on the surface of the electronic components to assist in heat dissipation. It is well known that electronic components such as a central processing unit generate a large amount of heat during the process. The electronic component is heated due to the accumulation of heat, which causes its operation to be unstable. The electronic component needs to be installed with _ (4) to dissipate heat. Usually, in order to fix the heat sink to the electronic component. In addition, you need a radiator buckle to fit s. ° ^1'0
