A docking station includes a connector, a first sliding component whereon a first incline and at least one incline are formed, and a second sliding component whereon a third incline is formed. When the second sliding component moves in a first direction so that the third incline slides relative to the first incline, the second sliding component pushes the first sliding component in a second direction for driving the connector to electrically connect with a notebook computer. The second sliding component further includes at least one protrusion. When the second sliding component moves in a third direction opposite to the first direction so that the protrusion slides relative to the second incline, the protrusion drives the first sliding component to move in a fourth direction opposite to the second direction so as to drive the connector to separate from the notebook computer.
