As a result, user force is required to axially move the shackle into the combination re-setting position.

Abstract: An inverted U-shaped combination lock is disclosed. The lock comprises a male locking mechanism a push ring, a hollow spindle, a sealing ring, an abutment ring, number rings, and a spring. The lock still can be opened without password by inserting a key into a keyhole prior to turning an angle of 90 degrees of the key, a ridged section of the mechanism is changed from a higher position to a lower one for disengaging the mechanism from the lock for subsequent removal of the mechanism. The invention also provides means for helping user know the forgot password and means for resetting the password.

Abstract: A mechanism of a combination lock for beginning and ending combination-changing operation includes a pressing block, which is fitted to a front end of the spindle of the combination lock and associated with a pad. The pad has posts contacting a most front one of several spring-loaded tooth dishes, which separably engage respective dials. The pressing block is pressed towards a rear end of the spindle to force the tooth dishes to disengage respective dials so that the dials can be turned relative to the tooth dishes for changing the unlocking numeral combination to a new one. When the combination changing operation is finished, the pressing block is pushed back to the original position for the tooth dishes to engage respective dials; thus, after the combination changing operation, movement of the pressing block back to the original position can't cause rotation of the dials accidentally.
