摘要：A combination lock comprises a lock seat, a dial set, a sliding seat, a locktongue, a resilient block, a lock seat cover, and a shackle having a movable end and afixed end. When the dial set is turned to a set series of numbers to work the mechanismthat opens the lock, the stopping rod of the dial set is not obstructed by the dial so as toenable the fixed end of the shackle to actuate the sliding seat. The movement of thesliding seat can bring about the displacement of the lock tongue without obstructing themovable end of the shackle, thereby enabling the movable end of the shackle to beejected by the resilient block. When the set series of numbers is disturbed, the stoppingrod of the dial set remains stationary such that the sliding set is urged by the stoppingrod, and that the sliding seat can not be moved by the fixed end of the shackle. Themovable end of the shackle is inserted into the fastening hole of the lock seat to bringabout the displacement of the lock tongue and is therefore retained securely by the locktongue.
