Abstract

A fastener ( ) includes a pin ( ), a spring ( ) and a handle ( ). The pin extends through a heat sink ( ). The handle is pivotably attached to a top portion of the pin. The pin has a foot ( ) extending through a mother board ( ) and a supporting board ( ) located under the mother board to engage with the supporting board. A CPU ( ) is mounted on the mother board. The spring surrounds the pin and is located between a base of the heat sink and the handle. When the handle is rotated from a horizontal position to a vertical position, the handle compresses the spring toward the foot. The spring in turn presses the base of the heat sink against the CPU.
