Claim:
1. A lock for an electronic device having a lock hole, comprising: a lock core operable and rotatable about a first axis; a fastener connected to the lock core; wherein the fastener includes at least two V-shaped like lever arms disposed at two opposite sides of a virtual axis and move respectively at each side of the virtual axis, each of the lever arms includes a pivot, an effort arm and a resistance arm located at two opposite sides of the pivot, wherein a movement of the at least two effort arms toward each other brings the effort arms close to the virtual axis and accompanies a movement of the at least two resistance arms away from each other and away from the virtual axis; wherein movement traces of the lever arms lie on a two-dimensional plane and the lever arms overlap thoroughly in a direction parallel to the two-dimensional plane so that one of the lever arms hides behind the other lever arm; and an adapter connected to the lock core and the fastener, comprising: wherein a rotation of the lock core about the first axis drives the adapter to drive the fastener to rotate about a second axis, wherein an opening of the U-shaped structure of the adapter moves toward the effort arms to have the effort arms gathering and received in the U-shaped structure; wherein when the lock core is locked, the lock core restricts the fastener from rotating; when the lock core is unlocked, the fastener is operably rotated.
