For this reason, the industry usually installs a heat sink on an electronic component to discharge a large amount of heat generated by it. In order to ensure that the heat sink and the electronic components can be in close contact and heat transfer is sufficient, it is usually necessary to assist the heat sink by means of a fastening device. For example, as shown in the seventh figure, a heat sink clip is disclosed, which has a buckle 51, and a buckle arm 511 is bent and extended at two ends thereof to be correspondingly hooked on opposite sides of the fixing base 7 The operating block 53 is disposed between the buckle 51 and the substrate 61 of the heat sink 60, so that the tail end 531 of the operating rod 53 is pivotally connected below the buckle 51. The segment forms a linkage rod portion 533. After the linkage rod portion 533 is rotated by an angle, the outer edge 535 can lift the buckle rod 31 so that the buckle arms 511 on both sides of the buckle rod 51 are fastened to the sides of the fixing base 6 The bumps 71 are such that the heat sink 60 is in close contact with the wafer. When the buckle is assembled, the hook lever 51 must be pressed first, and the buckle arms 5 ι at both ends are elastically fastened to the bumps 71 on both sides of the base, and then the operating lever 53 is turned to perform further pressing. Action to complete the installation. Further, in the unscrewing operation, the operating lever is first turned to the lower side of the lever 51, and the button 511 is separated from the projection 71 by the tool to remove the heat sink 60. Therefore, when the buckle of the structure is loaded or unloaded, it is laborious and numerous. [Inventive content] In view of the above, it is necessary to provide a heat sink fastening device which is convenient for fastening. - a heat sink fastening device comprising a pressing member, a movable member and a fixing member, and a lowering member is provided below the end portion of the member, the movable member is located at the other end of the ageing portion and is opposite to the fastening leg: The buckle-end is provided with a frame-rotating portion pivotally connected to the other end of the pressing member, and the buckle-shaped end is provided with a buckle that can be hooked on the reducing member, and the hinge is pivotally connected to The pivoting portion of the buckle wire can be moved up and down with respect to the pressing member. The sensing technology has the advantage of being like τ. The heat sink fastening device is turned over and buckled, and the other end of the buckle wire is made. The splicing portion drives the movable member to move upward, so that the 6 1300 683 clasp is tightly fastened to the corresponding bump on the fixing frame, so that the heat sink is closely attached to the electronic component, and the disassembly and assembly are labor-saving and convenient.
