Abstract: An electronic device includes a housing, a first electronic component, a second electronic component, two resilient assemblies, and two rotating levers. The housing defines an accommodating space. The second electronic component is fixed in the accommodating space. Each rotating lever includes a first end and a second end. A distance between the second end and a rotation shaft is less than a distance between the first end and the rotation shaft. A handle is rotationally fixed on the first electronic component. When the first electronic component slides into the accommodating space, the handle is rotated toward the first electronic component, the handle drives the two rotating levers to rotate and resist against the resilient assemblies, and the handle overcomes an elastic force applied by the resilient assemblies onto the rotating levers, so that the first electronic component connects with the second electronic component without gaps.
