Fastener for use in electronic device

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.
