ABSTRACT:
An improvement in a drawer lock of a cabinet includes a cylinder, a trigger bar, a fixing block, a sliding block, a latch hook, a first elastic member and a latch mechanism. The latch mechanism has a clutch pivotally engaged with a latch bar. A second elastic member keeps the clutch to be engaged with the latch bar at a preset angle. The latch hook of a closing drawer can wedge the latch bar to turn an angle smoothly while the clutch and the sliding block remain stationary, so as to prevent causing any damage to the latch hook even when the cabinet is in a locked position.
