The other end is moved, and the pressing portion 317 of the buckle 30 is from the gusset 60, the first sliding slot 613 of the fixing plate 10 of the fixing module 10, the second end of the second sliding slot 141, and the terminating end to the first end. The starting end slides to release the pressing portion 317 against the bottom edge of the first sliding groove 613 of the gusset 60. The pressing portion 317 of the clip 30 is further slid out of the second sliding slot 141 of the fixing plate 140 of the fixing module 10, and the heat sink 50 can be taken out from the fixed mold group 10. The positioning portion 315 of the fastener 30 of the heat dissipating device is rotatably coupled with the heat sink 50 and the fixed module 10, and the operating arm 33 of the buckle 30 is used to drive the buckle 30. The pressing portion 317 slides from one end to the other end in the first sliding slot 613 of the heat sink 50 gusset 60 and the second sliding slot 141 of the fixing module 10 fixing plate 140, so that the pressing portion 317 is directed toward the electronic component. The heat sink 50 is pressed against the heat sink 50 to abut the electronic component. The heat sink 50 can be removed from the electronic component by operating the operating arm 33 of the clip 30 in reverse. The installation and removal of the heat sink are quite convenient and labor-saving. In summary, the present invention complies with the requirements of the invention patent, and stipulates the application of the special J J 351 457 according to law, and the equivalent modification or benefit application. It is to be understood that the subject matter of the present invention is to be construed as being limited by the scope of the present invention.
