Hereinafter lift an actual Zuo that implements and Shuo Ming ︰

Refer to Fig. 4、Fig. 5，And be aided with refering to Fig. 2A、Fig. 3 B，When user is intended to radiator 31 is arranged on the electronic component 51 of motherboard 5，While directly radiator 31 being placed on fixture 2，By the first of the radiator 31、Two fasteners 33、35 respectively to should first、Two projection 21a、After 21b，Then by first、Two buckles 334、The first of 354、Two end of threads 3341、3541 be placed into contact with it is relative this first、Two hook part 211a、The lower section of 211b，Then pass through single handss of user finger (or also can two handss finger) to this first、Two pommels 3310、3510 exert a force downwards pulls，Make this first、Two connection ends 3311、3511 can be towards away to should first、Two shrinkage pools 3336、While movable upwards in 3536，This first、Two buckles 334、354 with catch on thereon (or clasping) first、Two projection 21a、21b can with this first、Two connection ends 3311、3511 toward top offset，Now this first、Two pressure section 23a、23b can by this first、Two projection 21a、21b pulls up further up upside (Fig. 5 A) of the displacement away from the motherboard 5，Until aforementioned first、Two connection ends 3311、3511 are each moved to first、Two rotating shafts 34、36 top，And this first、Two pommels 3310、3510 is adjacent to should first respectively、Two projection 21a、While 21b，First、Two fasteners 33、35 can be subject to this first、Two pressure section 23a、The elastic reactance of 23b and downward pulling force is produced to radiator 31，And this first、Two elastic 24a、24b can with this first、Two pressure section 23a、23b is pulled upwardly (or toward top offset) and elastic deformation is compressed on the bottom surface of respect thereto 32 after (Fig. 5 A)，The radiator 31 just can be interlocked with fixture 2 and share (Fig. 5)，And then the bottom surface centre of the base 32 of the radiator 31 can be fitted tightly on relative electronic component 51.

If be now intended to dismantle the radiator 31，Finger through single handss of user (or also can two handss finger) to this first、Two pommels 3310、3510 exert a force upwards pulls，Make first、Two connection ends 3311、3511 can each towards to should first、Two shrinkage pools 3336、In 3536 while activity downwards，This first、Two buckles 334、354 with catch on thereon (or clasping) first、Two projection 21a、21b can with this first、Two connection ends 3311、3511 unclamp gradually toward bottom offset，Now this first、Two pressure section 23a、23b also can with this first、Two projection 21a、21b is toward the upside of the motherboard 5 to bottom offset (Fig. 6 A)，Until this first、Two connection ends 3311、3511 are each located on corresponding first、Two shrinkage pools 3336、While in 3536，This first、Two elastic 24a、24b can be subject to first、Two pressure section 23a、23b restPoses (i.e. first after being displaced to downwards the upside for touching the motherboard 5、Two elastic 24a、The non-elastic deformations of 24b；Fig. 6 A) after, make the radiator 31 just can release (Fig. 6) with fixture 2, you can to dismantle the radiator 31.

Therefore through the design of this heat-sink unit fastener 1 of the invention, so that effectively save carrying out fixed heat sink 31 by other hand-held tools (such as screwdriver or wrench), use the effect for reaching that operation is easy to assembly and fastening is firm, and the effect for saving built-up time.

Fig. 8 is referred to, the exploded perspective schematic diagram of the second embodiment of the present invention is shown.The structure of the present embodiment is identical with aforementioned first embodiment with connection relationship and its effect, therefore here is not repeated again, at both differences is：Aforementioned heat-sink unit fastener 1 further includes a fixture 4, the fixture 4 is preferably implemented to be constituted with metal material (such as aluminum alloy material or galvanized iron material) in this, and the fixture 4 is with an opening 43, the opening 43 is opened in the centre of the fixture 4 and in naked sky, and the fixture 4 is explained with such as rear two kinds of aspects：Wherein the first aspect, refering to Fig. 8, Fig. 8 A, Fig. 8 B, the fixture 4 is arranged between the motherboard 5 and first and second elastic press part 2a, the 2b, that is, aforementioned first and second elasticity press part 2a, 2b are separately positioned in two relative branches 41 of the fixture 4 across the opening 21 each other, and the fixture 4 frames the electronic component 51 on motherboard 5, and electronic component 51 is located in the opening 21, make the electronic component 51 with to should the centre of opposite side of radiator 3 be mutually brought into close contact.

Second aspect, refering to Fig. 9, aforementioned fixture 4 is arranged on the downside of the motherboard 5, and two relative branches 41 of the fixture 4 across the motherboard 5 pairs should first and second elastic press part 2a, 2b, and sequentially screw lock is fed through two relative branches 41 and motherboard 5 and first and second fixed part 25a, 25b of first and second elastic press part 2a, 2b of the fixture 4 through plural screw piece 44.

So being arranged between the motherboard 5 and first and second elastic press part 2a, 2b or being arranged on the downside of the motherboard 5 through aforementioned fixture 4, the effect for effectively reaching enhancing (or increase) overall construction intensity is used.
