Claim:
A cover flip mechanism disposed at an electronic device comprising a first casing and a second casing, the cover flip mechanism comprising: a sliding mechanism connected to the first casing and the second casing, wherein the sliding mechanism is used for driving the first casing to slide relatively to the second casing to a rotating location; a rotating mechanism having a supporting portion and a rotating portion, wherein the rotating portion is disposed at the second casing and is connected to the supporting portion; a fastener pivotally connected to the second casing, wherein the fastener is used to fasten the supporting portion; and a protrudent block disposed at the first casing, wherein when the first casing slides relatively to the second casing to the rotating location, the protrudent block pushes the fastener to allow the fastener to rotate, the fastener rotates to move the supporting portion away from the fastener to separate the supporting portion and the fastener without contacting each other, and then the supporting portion can rotate relatively to the second casing via the rotating portion to push the first casing to rotate relatively to the second casing.
