ABSTRACT:

BACKGROUND OF THE INVENTION
U.S. Pat. No. 5,327,752 to Myers et al. disclosed a computer equipment lock having an axial pin tubular lock for use in securing portable computers having spindle-accepting port. However, the T-shaped head portion (
76
) on the cylindrical neck portion (
77
) should be rotated at a right angle to be retarded by the slotted port in the computer for locking the computer. For withdrawing the head portion (
76
) from the computer, it should be further rotated to be aligned with the computer slot in order to unlock the computer. Such a rotation of the head portion (
76
) of the spindle is inconvenient for the users especially for those disabled computer operators.
Meanwhile, such a prior art should be provided with suitable apertures allowing the free rotation of the spindle head (
76
) for locking or unlocking purpose, e.g., an aperture existing among the extensive members (
82
a
,
82
b
), the side wall of the computer slot and the spindle head (
76
); or an aperture existing in the computer slot since the spindle head (
76
) when locked is perpendicular to the computer slot without fully closing or shielding the computer slot; with these apertures rendering the opportunities for unexpected intrusion for unlocking the computer equipment lock, thereby decreasing its security effect.
The present inventor has found the drawbacks of the conventional computer equipment lock and invented the present computer lock having double locking leaves.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a computer lock including a housing (
1
) having a pair of locking leaves (
3
) respectively pivotally secured on a front end portion of the housing (
1
) with the two locking leaves (
3
) combinably flattened to be inserted through a computer slot (A), and an actuating device (
2
) slidably held in the housing (
1
) to be locked in the housing, whereby upon a forward pushing of the actuating device (
2
) to openly bias the two locking leaves (
3
) for extending the two leaves (
3
) to be retarded against the sidewall extension disposed around the computer slot, the computer will then be stably locked with the two locking leaves (
3
) of the computer lock.
