• an outer casing forming:
• an accommodating space;
• and
• a cavity communicating with the accommodating space;
• a lock core rotatably mounted through the outer casing and comprising:
• an inner casing rotatably mounted through the accommodating space of the outer casing and comprising:
• a key way;
• and
• at least one hole;
• one end of each one of the at least one hole communicating with the key way;
• at least one slider movably mounted through the at least one hole and capable of rotating with respect to the corresponding hole about a rotating axis parallel with an extending direction of the corresponding hole;
• each one of the at least one slider comprising:
• a slider main body having:
• a recessed portion;
• and
• a positioning portion securely mounted on one end of the slider main body and located in the key way;
• a sectional shape of the positioning portion being non-circular;
• at least one first elastic component mounted in the inner casing and connected to the at least one slider respectively and thereby the slider tending to move toward the key way;
• at least one block movably mounted through the inner casing;
• each one of the at least one block comprising:
• a block main body, a portion of the block main body selectively received in the cavity of the outer casing;
• and
• at least one protrusion portion selectively received in the recessed portion of one of the at least one slider;
