ABSTRACT:
A convertible lock structure includes a main body including a lock core received therein and a latch rod extending from an end thereof. The main body includes a transverse hole defined therein for receiving an end of a spring-biased control latch. A casing receives the main body and includes an end wall through which the latch rod extends. The casing further includes at least two positioning holes one of which is selected to receive the second end of the control latch. A second end of the control latch is operable by a proper key so as to move between a retracted position inside the main body which allows the main body to move in the casing and an extended position beyond the transverse hole to retain the main body in position.
