ABSTRACT:
A direction changeable lock has a latch case, a latch bolt, and a positioning rod which can easily be turned around manually through 180 degrees, so that it does not have a direction limitation when it is to be fixed on a door. The latch bolt has a recess for an anti-burglary bolt therein.
