Abstract: An anti-theft lock for a portable electronic device has a mounting shaft, two buckling units, a split-abutting unit, and a controlling unit. The two buckling units are moveably mounted around the mounting shaft. The split-abutting unit is moveable and has an engaging end and a split-abutting end. The split-abutting end selectively abuts the two buckling units via the movement of the split-abutting unit. The controlling unit has an annular curved surface. The annular curved surface slidably abuts the engaging end of the split-abutting unit. During the rotation of the controlling unit, the annular curved surface is capable of pushing the split-abutting unit to make the split-abutting end abut the two buckling units with inclined surfaces to move the two buckling units away from each other. The larger a distance the split-abutting unit moves, the larger a distance the two buckling units move away from each other.

Abstract: A universal security lock for portable electronic devices has an engaging mechanism which has a base, an expanding rod, and two gripping fingers. The expanding rod is slidable along an engaging direction. Each of the gripping fingers is pivotally mounted on the base and disposed on a respective side of the expanding rod. When the expanding rod is moved toward the engaging direction, an end of the expanding rod abuts against the two gripping fingers and expands the gripping fingers gradually such that the gripping fingers can be engaged in security slots of a portable electronic device. At least one of the gripping fingers has a protrusion extending toward the other gripping finger. The expanding rod selectively abuts against the protrusion to further expand the gripping finger.

Abstract: A universal security lock for portable electronic devices has a base and a lock core. An operating part, a blocker, a displacement absorber, an expanding rod, and two gripping fingers are arranged in the base. The operating part is slidably mounted through the rear opening and is slidable toward the front opening to an engaged position. The displacement absorber is a spring or two mutually repelling magnets that drive the operating part and the expanding rod away from each other. The two gripping fingers are pivotally mounted to the base and disposed on a front opening of the base. When the operating part is in the engaged position, the displacement absorber pushes the expanding rod toward the front opening to move the outer ends of the two gripping fingers away from each other gradually such that the gripping fingers engage with security slots of different widths.

Abstract: A universal security lock for portable electronic devices has a lock case and a lock core. The lock core, a displacement absorber, an expanding rod, and two gripping fingers are arranged in a passage of the lock case. An operating part of the lock core is movable inwardly into the passage to an engaged position. The displacement absorber is a spring or two mutually repelling magnets that drive the operating part and the expanding rod to move away from each other. The two gripping fingers are pivotally mounted on a front opening of the lock case. When the operating part is in the engaged position, the displacement absorber pushes the expanding rod toward the front opening to move the outer ends of the two gripping fingers away from each other gradually such that the gripping fingers engage with security slots of different widths.

Abstract: A pulling locking device has a cord, a lock module, an engaging seat and a mounting seat. The lock module, the engaging seat and the mounting seat are mounted around the cord. The lock module has a lock casing, a lock core and a sliding element. The sliding element is slidable relative to the lock casing to selectively engage with the engaging seat only when the lock core is unlocked. When the pulling locking device is in use, a portable electronic device is clamped between the engaging seat and the mounting seat. With the cooperation of the lock module and the engaging seat, the portable electronic device can be fixed in position without any further structural design particularly for the locking device, which lowers the manufacturing cost, and enables the pulling lock device to be adapted for various kinds of portable electronic devices.
