A lock includes a body, a key-operable locking mechanism and a rotational indicator. The locking mechanism includes a spindle and a block. The spindle includes a key hole in an end and is connected, at another end, to the block to allow the block to be rotated from a locking position to an unlocking position. The indicator is disposed in the lock body, and includes, at a front end, a recess for receiving the block. With the indicator in the original position, as the block is rotated to the unlocking position, the block pushes a first side wall of the recess of the indicator to rotate the indicator to an indicating position. When the indicator is in the indicating position, a space is defined between a second side wall of the recess of the indicator and the block, and the block is moved in the space. |
