Abstract
A cover mechanism includes a covering whereon a circular hole is formed, and a button installed inside the circular hole. At least one track is formed on the button. The cover mechanism further includes at least one locking component. A first end of the locking component is disposed on the track in a movable manner, and a second end of the locking component is for inserting into a slot of a housing so as to lock the covering on the housing. When the button rotates in a first direction, the track drives the first end to move away from a center of the button so that the second end inserts into the slot. On the other hand, when the button rotates in a second direction, the track drives the first end to move close to the center of the button so that the second end separates from the slot.
