Patent ID: 8665585

Claim:
A cover mechanism for covering a hole on a casing, the cover mechanism comprising: a base; a first holder disposed on the base; a second holder disposed on base and adjacent to the first holder; a cover pivotably disposed on the first holder, the cover pivoting relative to the first holder for rotating from a first position to a second position, a connecting hole being formed on the cover, and a resilient component for constraining the cover at the second position, the resilient component comprising: a shaft pivoting to the second holder; and a curved portion, a first end of the curved portion being connected to the shaft, a second end of the curved portion different from the first end pivoting to the cover via the connecting hole, the cover driving the curved portion to generate resilient deformation when rotating from the first position to the second position, and a resilient recovering force of the curved portion by the resilient deformation being for stopping the cover at the second position.
