[Prior art]

 Computers have become a necessary equipment for modern people or companies, and the execution speed of computer CPUs has also become more important to users. However, an increase in the execution speed of a component such as a CPU, a printer, or a chip results in an excessively high temperature, and the component such as a CPU or a chip is burned. To effectively lower the temperature of the CPU, an aluminum press heat sink 2 'is placed on the CPU, a fan 1' is placed on the aluminum press heat sink 2 ', and the heat sink 2' is screwed on the heat sink 2 '. It is fixed between two adjacent fin pieces 21 '. Thus, the heat sink 2 'and the fan 1' dissipate the heat energy generated by the CPU or chip (see FIG. 1). However, the execution speed of the CPU is further increased, the rotation speed of the fan is increased, and the thickness of the heat sink is reduced for effective heat radiation. Then, the heat sink 2 ′ becomes flexible and the fan 1 ′ cannot be fixed thereon, so that the fan 1 ′ is connected to the bottom 22 of the heat sink 2 ′ by the plurality of hooks 11 ′ extending downward. And fix fan 1 '(see Fig. 2). Since the hooks 11 'are very long and have elasticity, they are liable to be vibrated or cut, and have a drawback that the fan 1' is loosened or dropped. Further, in the one shown in FIG. 3, a support cover 23 'is provided on the four circumferences of the heat sink 2', and the fan 1 'is fixed to the bottom 22' of the heat sink 2 '. This allows the fan 1 'to be fixed to the support cover 23' which is soldered to the four circumferences of the heat sink 2 '. However, when the support cover 23 'is made of metal and soldered to the four circumferences of the heat sink 2', the construction is inconvenient and the weight increases.

[Problems to be solved by the invention]

 SUMMARY OF THE INVENTION An object of the present invention is to provide a kind of fastener for a heat radiating device in view of the disadvantages of the structure of the well-known heat radiating device. That is, a fixed frame is provided with a plurality of downwardly extending parallel fixing pieces, can accommodate two heat sink fins between two adjacent parallel fixing pieces, and has a plurality of perforations between two adjacent parallel fixing pieces. When the fixing frame is inserted into the heat sink, the screw can be screwed between two adjacent parallel fixing pieces by drilling, and the two heat sink fins are tightened between the fixing pieces by the threads on both sides of the screw. The fan can be easily fixed on the heat sink.
