The lock structure has a main body with a lock cover and a latch rod. The main body has a transverse hole for receiving the end of a spring-biased control latch. A casing receives the main body and has an end wall through which the latch rod extends. The casing has two positioning holes, one of which receives the second end of the control latch. The second end of the control latch is operable by a proper key 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. |
