1. A securing mechanism adapted to be mounted onto a base beside a heat source for attaching a heat dissipation element onto the heat source, the securing mechanism comprising:a first fixing part;
a second fixing part; and
a first arm and a second arm connected with the first fixing part and the second fixing part, wherein a first bent structure is protruded from the first arm and extends toward the second arm, a second bent structure is protruded from the second arm and extends toward the first arm, and the first bent structure and the second bent structure connect or overlap with each other between the first arm and the second arm to define a force-receiving surface collaboratively,
wherein when the first fixing part and the second fixing part are mounted to the base, the heat dissipation element is pressed by the force-receiving surface collaboratively defined by the first bent structure and the second bent structure to be attached onto the heat source.
