ABSTRACT:
A combination padlock comprises a housing, a shackle, and a numbered wheel set. The housing is made up of a front housing and a rear housing. The shackle has a hooked portion and a rod-shaped body. The numbered wheel set comprises a seat on which a locking mechanism is disposed for actuating a movable grid plate to move up and down. The front housing is provided with a receiving cell having a position restricting block, whereas the rear housing is provided with a receiving cell having a position restricting block and a retaining block. The position restricting block is intended to confine the rod-shaped body of the shackle while the retaining block is engageable with the retaining recess of the rod-shaped body of the shackle at such time when the shackle is pulled upwards.
