ABSTRACT:
A pad lock includes an outer casing, a lock main body, and a shackle. A stem is slidably mounted in the lock main body. Several number wheels are rotatably mounted around the stem. Also rotatably mounted around the stem are several retaining sleeves each being releasably engaged with an associated number wheel to rotate therewith. A lever member includes a first end for releasably engaging two pin members to retain the shackle in a locked status. The lever member includes a second end with a number of tongues for engaging with the retaining sleeves. A positioning member is formed on the second end of the lever member. A safety pin is mounted to the lever member to assure the positioning member in a position that prevents setting of a new code when any one of the number wheels is not in the correct position for unlocking.
