Abstract
A combination lock includes a core unit, a locking mechanism, and a reset mechanism formed of a guide rod, a sliding plate, a stop rod and a reset member. The sliding plate is downwards to push the locking mechanism to the unlocking position wherein operation buttons pressed subject to the set code. When the locking mechanism lifted to push the reset member of the reset mechanism, the locating rod of the reset member pushes the stop rod away from the rack of the sliding plate, enabling the sliding plate to be returned by a spring member so that the core unit is returned to the initial position for resetting the code.
