ABSTRACT:
It is an improvement for a combination padlock, which comprises mainly a main shaft for mounting, a combination wheel assembly; the main shaft has a T-shaped slot for receiving a T-shaped block therein. There are two springs being mounted between the T-shaped block and the T-shaped slot; the main shaft has a center hole for loading two lock tumblers therein; there is a spring being mounted between the two lock tumblers to maintain a pushing force to the tumblers. After the main shaft is mounted with the combination wheel assembly, an end cap is fixedly attached to an end of the main shaft. Since there is a given flexible distance between the two lock tumblers set with the T-shaped block, the padlock can be locked up or unlock easily under a security condition.
