description A dual-unlock combination lock provides a first set of correct password and a second set of correct password to be used independently. After a password switch pushbutton is operated to drive a bracket to a corresponding position, a corresponding correct password is input into a combination wheel, so that an elastic member props the bracket to release from a transmission element in order to unlock the combination lock. One password element can achieve the effect of unlocking the lock by using two sets of correct password independently to provide a broader scope of applicability. The first set of correct password with the setting and use similar to those of a common password is provided for ordinary users, and the second set of correct password is a fixed code provided for designated users to unlock the combination lock by scanning an identification code by a mobile terminal.
