A padlock with a quickly changeable shackle comprises a locking core (3), a locking member(4), blocking balls(5,5') a lock body(1) on which two limb receiving chambers(11,12) and a passage(13) are disposed, and a shackle(2) which is U-shaped and is defined by a longer and a shorter parallel limbs(21,22) respectively received in the limb receiving chambers(11,12) to lock the padlock. A ring groove(211) with an abutment head is disposed at the free end of the longer limb(21) and a depressed portion(212) with a screw hole(213) is provided on the circumferential surface of the abutment head. A shackle changing screw(7) is threaded into the screw hole(213) and the end face of the screw(7) in the threaded position is higher than the depressed portion(212) and lower than the circumferential surface of the abutment head. The invention further provides a padlock having a freely-convertible deadlock mechanism (figures 7(a) and 8(a)). |
