Dual key lock core and key lock core assembly using the same

A dual key lock core, comprising:

• a lock core rod including a wedging part and an inner barrel disposed at opposite ends, wherein a first lock structure is disposed on a circumferential edge of an inner surface of the inner barrel near an opening of the inner barrel;
• a driving rod rotatably caped within the inner barrel, the driving rod has a second lock structure disposed on one end of an outer surface of the driving rod;
• and
• an outer barrel having a first end and a second end opposite to the first end, the second lock structure is exposed by the second end of the outer barrel;
• when the dual key lock core is in a locked state, the lock core rod and the driving rod engage with the outer barrel, the rotation of the lock core rod and the driving rod relative to the outer barrel are restricted;
• when the driving rod moves toward the wedging part, the restriction to the rotation of the driving rod and the lock core rod relative to the outer barrel are released.
