The end of the snap arm 122 is bent inwardly with -= and the portion of the mother-buckle arm 122 is removed to form the first inclined surface 122a. The elastomer 14 is a spring. The rod body 16 includes a cylindrical body 162, and the bottom end of the body 162 extends downward to form a fixed structure. In the embodiment, the fixed structure is a stud, and the body is separated by a large diameter (four) stud 164. The diameter. A plurality of latching arms 122 corresponding to the heads 12 of the main body 162 are respectively provided with a receiving slot, and a stopper 162b is protruded outwardly from the bottom of each of the recesses 162a, and the outer surface of each of the latches 162b Forming a second inclined surface 162c matching the shape of the first inclined surface 122& the second inclined surface 162c can guide the buckle arm 122 of the head portion I2 to slide in to enable the two fastening arms 122 of the head 12 to be borrowed The hooks 123 are respectively engaged with the two blocks 162b so that the head 12 and the rod 16 are combined to form a whole. The stud 164 is threaded for locking with components such as a circuit board (not shown). The opposite sides of the body 162 are adjacent to the stud 164, and a supporting portion 166 is protruded outwardly. Referring to FIG. 2 and FIG. 3, when the clip 10 is assembled, the elastic body 14 is first placed along the rod. The top end of the body 16 is sleeved downwardly on the body 162 of the rod body 16, and then the head portion 12 is fastened to the rod body 16 to form a unit. The upper end of the elastic body 14 can be pressed against the head portion 12. The blocking portion 1258825 166 of the rod body 16 is formed to have a maximum width larger than the inner diameter of the elastic body 14, so that the elastic body 14 is restrained on the head portion. 12 and the stopper portion 166 are not easily peeled off (as shown in FIG. 3). Referring to FIG. 4, each sleeve 222 includes a bottom portion 222a. The bottom portion 222a is provided with a through hole 222b. The size of the through hole 222b is substantially equal to the outer diameter of the body 162 of the rod body 16. The edge of the through hole 222b is further provided. Opposing the two notches 222c, the two notches 222c are disposed corresponding to the supporting portion 166 of the rod body 16, so that the supporting portion 166 can just pass through the notches 222c when aligned, and when the blocking portion 166 is When the notches 222c are offset from a certain angle, they are supported by the edges of the perforations 222b. Referring to FIG. 5 to FIG. 8 , when the fasteners 10 are pre-assembled onto the base 22 , the fasteners 10 assembled with the elastic body 14 are placed in the sleeves 222 , and the buckles 10 are pressed. The head 12 is such that the stud 164 and the stopping portion 166 of the rod 16 pass through the through hole 222b of the bottom portion 222a of the sleeve 222 along the notch 222c (as shown in FIG. 5), and then the buckle 1 is rotated. That is, the blocking portion 166 of the rod 16 abuts against the edge of the perforation 222b (as shown in FIGS. 6 and 7), and the pressing of the head portion 12 and the bottom portion 222a of the sleeve 222 will be removed. The elastomer 14 is compressed to pre-assemble the fasteners 1() onto the base 22 of the heat sink 20 (as shown in Figure 8). Finally, the heat sink can be combined and fixed to the heat-generating electronic component by means of the stud 164 being locked to the circuit board. Referring to Figure 9, there is shown a perspective exploded view of a buckle according to another embodiment of the present invention. The buckle is different from the first embodiment in that the head 4 12a and the cup are made into a body, and the portions 16 are formed as 1508825: the width and the j are equal to or equal to the inside of the elastic body 14. The diameter of the elastic body I4 can be set from the bottom end of the dry body 16a to the body 163 of the rod body 16a, and can be abutted against the head portion 12a. Referring to FIG. 1A, in order to prevent the elastic body 14 from falling off the cup body 16a, the length of the stopper portion located on the left side of the rod body 16a is greater than the length of the broadcast portion located on the right side of the rod body 16a. The length of the protrusion is such that the elastic body 14 is left by the block jL# 166a located on the left side of the rod body 16a. The two stoppers are attached to the base 22 of the heat sink 20 by the surface of the fasteners 103. It can be seen from the above that the locking member 10 or 10a can be conveniently assembled to the heat sink 20 by the arrangement of the reading portions 166, 166a of the rod 16 or 16a and the through holes 222b and 222c of the sleeve 222. on. Since the supporting portion 166 or 166a is integrally formed with the rod body 16 or the other, the buckle 10 or 10a is firmly detached from the base 22 of the heat sink 2''. It will be appreciated that the studs 164 described above may be replaced with other securing structures such as snap-on buckles, barbs or interlocking structures. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art will be included in the following claims.
