While the first and second pommel 3310,3510 is pulled by upward force, first and second connecting pin 3311,3511 meetings Respectively towards moving in corresponding first and second shrinkage pool 3336,3536, at this time first and second fastener 33,35 with it is convex with respect to first and second Block 21a, 21b are in release state (refering to Fig. 6, Fig. 6 A)；If the first and second pommel 3310,3510 is pulled same by downward force When, which can be towards far from the upward activity of corresponding first and second shrinkage pool 3336,3536 (or mobile) To after 34,36 top of the first and second shaft, first and second fastener 33,35 and opposite first and second convex block 21a, 21b are in button at this time Conjunction state (refering to Fig. 5, Fig. 5 A).In addition, from top to bottom pulling the first and second handle portion 331,351 in fastening in the present embodiment State, and the first and second handle portion 331,351 is pulled from the bottom up, it is explained in the state of releasing, however, it is not limited to this.Tool When body is implemented, design can also be changed, the first and second handle portion 331,351 is pulled in buckling state from the bottom up, and from top to bottom First and second handle portion 331,351 is pulled, in the state that releases, closes elder generation Chen Ming.

An actual implementation is lifted below to explain:

Fig. 4, Fig. 5 are please referred to, and is aided with refering to Fig. 2A, Fig. 3 B, when user is intended to radiator 3 being mounted on motherboard 5 When on electronic component 51, while directly radiator 3 can be placed on fixing piece 2, by the first and second fastener of the radiator 3 33,35 respectively correspond first and second convex block 21a, 21b after, then by the first and second end of thread of the first and second buckle 334,354 3341,3541 it is placed into contact with the lower section with respect to first and second hook part 211a, 211b, then penetrates the single hand of user The finger finger of two hands (or can also) to first and second pommel 3310,3510, force is pulled downwards, enable this first and second connect Connect end 3311,3511 can towards in far from corresponding first and second shrinkage pool 3336,3536 upwards it is movable simultaneously, first and second buckle It 334,354 can be past with first and second connecting pin 3311,3511 with first and second convex block 21a, the 21b for catching on (or clasping) thereon Upper displacement, first and second pressure section 23a, 23b can be pulled up by first and second convex block 21a, 21b and then be up displaced remote at this time Upside (Fig. 5 A) from the motherboard 5, until aforementioned first and second connecting pin 3311,3511 is each moved to the first and second shaft 34, while 36 top and first and second pommel 3310,3510 distinguish adjacent correspondence first and second convex block 21a, 21b, the One, two fasteners 33,35 will receive the elastic reactance of first and second pressure section 23a, 23b and pull down to the generation of radiator 3 Power and first and second elastic portion 24a, 24b can be pulled upwardly (or being up displaced) with first and second pressure section 23a, 23b And flexible deformation compresses on the bottom surface of opposite pedestal 32 after (Fig. 5 A), which can be engaged with fixing piece 2 and share (Fig. 5), And then the bottom surface centre of the pedestal 32 of the radiator 3 can be fitted tightly on opposite electronic component 51.

If be intended to dismantle the radiator 3 at this time, through the single hand of user finger (or can also two hands hand Refer to) to first and second pommel 3310,3510, force is pulled upwards, and enable the first and second connecting pin 3311,3511 can be respectively towards correspondence In first and second shrinkage pool 3336,3536 downwards it is movable simultaneously, first and second buckle 334,354 and catch on (or clasping) thereon First and second convex block 21a, 21b can be unclamped gradually with first and second connecting pin 3311,3511 toward bottom offset, at this time this One, two pressure section 23a, 23b also can with the first and second convex block 21a, 21b toward the upside of the motherboard 5 to bottom offset (figure It 6A), should while first and second connecting pin 3311,3511 is each located in corresponding first and second shrinkage pool 3336,3536 First and second elastic portion 24a, 24b will receive after first and second pressure section 23a, 23b be displaced to downwards the upside for touching the motherboard 5 And (the i.e. non-elastic deformation of the first and second elastic portion 24a, 24b that restPoses；Fig. 6 A) after, it enables the radiator 3 and fixes Part 2 can release (Fig. 6), i.e., the detachable radiator 3.

Therefore through the design of this heat-sink unit fastener 1 of the invention, so that effectively saving by other hand-held tool (such as screws Bottle opener or wrench) carry out fixed heat sink 3, when using and achieve the effect that operation is easy to assembly and it is firm to fasten, and saving assembling Between effect.

Referring to Fig. 8, the exploded perspective schematic diagram of the second embodiment of the display present invention.The structure of the present embodiment and company Junction relationship and its effect are identical as aforementioned first embodiment, therefore do not repeat again herein, the two difference be in: aforementioned heat dissipation is single First fastener 1 further includes a fixing piece 4, which preferably implements in this with metal material (such as aluminum alloy material or galvanized iron material Matter) it is constituted, and the fixing piece 4 has an opening 43, which is opened in the centre of the fixing piece 4 and in naked sky, and The fixing piece 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 fixing piece 4 setting Between the motherboard 5 and first and second elastic press part 2a, the 2b, that is, aforementioned first and second elastic press part 2a, 2b is each other In two opposite branches 41 that the opening 21 is separately positioned on the fixing piece 4, and the fixing piece 4 frames on motherboard 5 Electronic component 51, and electronic component 51 is located in the opening 21, enable the electronic component 51 and the other side of the corresponding radiator 3 it Centre mutually fits closely.

Second aspect, refering to Fig. 9, aforementioned fixing piece 4 is arranged on the downside of the motherboard 5, and the two-phase of the fixing piece 4 Pair branch 41 across the motherboard 5 corresponding first and second elastic press part 2a, the 2b, and through plural screw piece 44 sequentially spiral shell Lock is fed through two opposite branches 41 of the fixing piece 4 and the first and second of motherboard 5 and first and second elastic press part 2a, 2b and fixes Portion 25a, 25b.

So between the motherboard 5 and first and second elastic press part 2a, 2b or being arranged through the setting of aforementioned fixing piece 4 On the downside of the motherboard 5, uses and effectively achieve the effect that enhancing (or increase) overall structural strength.
