Problems solved by technology

[0002] When the traditional leaf padlock is produced, the matching cover has an unreasonable structure and is easy to be pried open by external force, which eventually leads to the phenomenon that the strength of the lock is not enough, which affects the quality of the lock.

In addition, the old-fashioned stuffy cover has a relatively high material cost during production, and the process is cumbersome, which takes up manpower and material resources, and must be equipped with a snap ring to be used together, which increases the manufacturing cost virtually. Therefore, the traditional stuffy cover can no longer meet the actual production needs.
