An anti-vandal padlock has a base, a buckling unit, two anti-sawing sleeves, a ball, and a locking mechanism. The base has a mounting passage and an annular groove formed on an inner surface of the mounting passage. The buckling unit has two straight segments. The second anti-sawing sleeve is rotatably and axially-movably mounted in the mounting passage, and has a ball hole. The ball is mounted in the second anti-sawing sleeve and is capable of protruding out of the ball hole. In the locked state, the locking mechanism makes the ball engage in the annular groove to limit movement of the second anti-sawing sleeve, such that the buckling unit cannot be detached from the second anti-sawing sleeve. The two anti-sawing sleeves are rotatably mounted on the two straight segments such that the buckling unit cannot be sawn off and has a better anti-theft ability.
