Fastener for use in electronic device

1. A fastener for use in an electronic device, including:

a positioning unit, axially formed with an insertion hole, wherein a first supporting concave part allowing a first electronic device to be disposed is radially formed on one surface of said positioning unit, and another surface thereof has a positioning structure communicating with said insertion hole and allowing a board member to be connected; and

a clamping member, having a main body, wherein a fastening pin inserted in said insertion hole is disposed at a bottom end of said main body, so that said bottom end of said main body enables said first electronic device disposed on said first supporting concave part to be in a locked status; said main body has a second supporting concave part allowing a second electronic device to be disposed and radially formed at a location opposite to said fastening pin, wherein an axial spacing distance is formed between said first supporting concave part and said second supporting concave part, a chamber is disposed at a location adjacent to one side of said second supporting concave part, said chamber has a pair of sliding slots oppositely arranged and a rod hole; and a sliding cover, having a sliding sheet axially protruded from a bottom surface thereof so as to be disposed in said chamber, two sides of said sliding sheet have a pair of sliding hooks buckled in said pair of sliding slots, and a sliding rod is protruded from said sliding sheet and sleeved with a spring, and said spring is located between said sliding sheet and said chamber; with said sliding cover sliding or being released, said spring is able to be in an energy storing status or an energy releasing status, so that a front end of said sliding cover is able to be released or be located above said second supporting concave part, thereby enabling said second electronic device to be in an unlocked status or a locked status.

2. The fastener for use in the electronic device as claimed in claim 1 , wherein said insertion hole is not a round hole, and a cross section of said fastening pin is formed in a shape which is the same as said insertion hole.

3. The fastener for use in the electronic device as claimed in claim 1 , wherein two sides of said first supporting concave part have a pair of first blocking edges abutting against a first positioning recess of said first electronic device; and two sides of said second supporting concave part have a pair of second blocking edges abutting against a second positioning recess of said second electronic device.

4. The fastener for use in the electronic device as claimed in claim 1 , wherein said positioning structure has at least two buckle hooks annularly arranged and protruded from a circumference of said insertion hole, said buckle hooks are used for being buckled in a board hole of said board member; wherein a length of said fastening pin is greater than a depth of said insertion hole, thus said fastening pin is allowed to protrude into a penetrated slot formed between said buckle hooks, and said buckle hooks are prevented from inwardly retracting and deforming.

5. The fastener for use in the electronic device as claimed in claim 4 , wherein a rotation preventing protrusion protruding from a circumference of said insertion hole is disposed between every two adjacent said buckle hooks, and said rotation preventing protrusion is inserted in a rotation preventing hole communicating with said board hole.

6. The fastener for use in the electronic device as claimed in claim 1 , further including a connecting strip, one end of said connecting strip is connected to said positioning unit, and another end thereof is connected to said main body of said clamping member, so that said positioning unit, said clamping member and said connecting strip are allowed to be formed through a high polymer insulation material being processed with an injection molding treatment.

7. The fastener for use in the electronic device as claimed in claim 1 , wherein an anti-loosening structure is correspondingly disposed at adjacent circumferences of said fastening pin and said insertion hole.

8. The fastener for use in the electronic device as claimed in claim 7 , wherein said anti-loosening structure has at least one anti-loosening buckle slot formed at an outer circumference of said fastening pin, and an anti-loosening buckle ring disposed at an inner circumference of said insertion hole; or said anti-loosening structure has an anti-loosening buckle ring formed at said outer circumference of said fastening pin, and at least one anti-loosening buckle slot formed at said inner circumference of said insertion hole.

9. The fastener for use in the electronic device as claimed in claim 1 , wherein said chamber has a front wall and a rear wall oppositely arranged above a bottom wall, and a pair of lateral walls connected between said front wall and said rear wall; wherein, said pair of sliding slots are oppositely formed on said pair of lateral walls, and said rod hole is formed on said rear wall.

10. The fastener for use in the electronic device as claimed in claim 9 , wherein said pair of lateral walls are correspondingly formed with a pair of guiding inclined surfaces arranged above said pair of sliding slots, said sliding sheet has a guiding arc-shaped surface arranged between said pair of sliding hooks; when said guiding arc-shaped surface displaces along said pair of guiding inclined surfaces, said pair of guiding inclined surfaces are formed in a slightly expanding and deforming status for allowing said pair of sliding hooks to smoothly pass said pair of guiding inclined surfaces so as to be buckled in said pair of sliding slots.

11. The fastener for use in the electronic device as claimed in claim 9 , wherein said front wall has an accommodation slot, a reinforcing rib is integrally protruded from said sliding sheet at a location corresponding to said accommodation slot, and said reinforcing rib is received and abutted against said accommodation slot.
