The invention is to provide a snapping device comprising an elongated clinging mechanism including a pivotal lever at either end wherein centers of rotation of the pivotal levers and the clinging mechanism are at different horizontal levels; and two post-shaped resilient elements disposed adjacent ends of the clinging mechanism wherein each resilient element passes through a support of a cooler and a circuit board to secure to an abutment plate at the other opposite side of the circuit board, the resilient elements will be expanded if the pivotal levers are rotated, and the clinging mechanism is mounted on the cooler by a stored returning force of the expanded resilient elements, thereby stably resting the cooler one a chip member on the circuit board.
