The anti-theft property of the lock can be made extremely high. (2) When the secondary lock is installed at a position that is not covered by the handle at the locking angle, when the secondary lock is installed at a position that is covered by the handle at the locking angle, the structure of the secondary lock device is the same, and each component Can be used in common.

(3) The secondary lock can be easily replaced from the front side of the handle lock only when both the main lock and the secondary lock are unlocked, so that unauthorized removal of the secondary lock can be prevented. The advantage is that, when both locks are unlocked, the secondary lock can be taken out from the front, so that the replacement of the secondary lock of the handle lock is more convenient than the work of removing from the back side of the door as in the conventional case. (4) Since the fixing fitting for locking the secondary lock can be released only when the sleeve is rotated to the unlocking angle together with the handle, there is an effect that double removal of the secondary lock is prevented. (5) The above-mentioned pull-out prevention mechanism for the secondary lock can be applied to a type in which both the main lock and the secondary lock are different from the type in which the handle is directly locked.

(6) Some customers may wish to use a double lock type handle lock, and some customers may wish to use only one lock type handle lock. Although some customers want to change to a locking handle lock, this handle lock can be replaced with a dummy lock instead of a secondary lock, so that it is possible to meet the needs of such various customers. (7) The above-mentioned dummy lock can also be applied to a type in which both the primary lock and the secondary lock are different from the type in which the handle is directly locked.
