Abstract
A combination lock with dual key numbers includes a casing, a latch, a locking piece and a plurality of restricting assemblies. The latch is slidingly provided in the casing, and the locking piece is pivotally provided in the casing. The latch has an abutting portion and a plurality of protrusions. The locking piece has a plurality of locking grooves. The restricting assemblies are rotatably provided outside the latch. Each of the restricting assemblies comprises a restricting piece, a first braking piece and a second braking piece. The first braking piece and the second braking piece are restricted by the restricting piece. The second braking piece has a guiding slot corresponding to the protrusion. With the relative rotation among the restricting piece, the first and second braking pieces, a user can set two independent groups of key numbers, which can unlock the combination lock, thereby increasing the convenience in use.
