See also Fig. 2 to Fig. 6, this creation buckling device of radiator 1 is to be compressed on the cover cap 40, and by with the fastening of a framework 60 radiator 50 being closely adhered on the central processing unit 70, wherein this framework 60 is to be interlockingly connected with mainboard 80 and these central processing unit 70 frames are put therein.

The convex respectively support 42 that is provided with of the two side ends of these cover cap 40 end faces.Four corners of this framework 60 have respectively upwards protruded out a button arm 62, also are provided with a button hole 64 on this button arm 62.

This buckling device of radiator 1 comprises a press body 10, two operating bodies 20 and two buckling bodies 30.This press body 10 roughly is square frame shape, its central authorities be provided with that two parallel interval arrange by branch 12, with corresponding being pressed on two supports 42 of these cover cap 40 end faces respectively, each two end by branch 12 extends a shell fragment 14 respectively and the suitable elasticity of tool obliquely, and the end of each shell fragment 14 vertically downward further bending extend a cantilever 16, the vertical respectively excurve of end both side edges that leans on of this cantilever 16 folds a supporting seat 17, all be provided with one first through hole 18 on each supporting seat 17, and 16 on two cantilevers of same side are provided with a crossbeam 19.

This two operating body 20 is equipped with an Actuator Division 22, a junction 24 is extended in the vertical separately outwards bending in the two ends of each Actuator Division 22 1 side, the both side edges appropriate position of this connecting portion 24 laterally protrudes out one first latch 28 respectively outwardly, and these connecting portion 24 both side edges laterally protrude out one respectively outwardly and can insert in first through hole 18 of this press body 10 and this two operating body 20 is connected second latch 29 at these press body 10 two ends below this first latch.

This two buckling body 30 is equipped with a pars intermedia 32, the spaced pin joint seat 34 of pair of parallel is extended at the last lateral margin two ends of each pars intermedia 32 respectively vertically upward, all offer on each pin joint seat 34 one can be respectively for first latch, 28 corresponding inserted of this two operating body 20 and with this two operating body 20 and these two buckling bodies, 30 corresponding second through holes 36 that link together, and under each buckling body 30 two ends of lateral margin extend vertically downward respectively one with the button hole 64 of this framework 60 clasp 38 of corresponding snapping one by one.
