A locking apparatus uses a handle pivotally connected to a base to control the movement of a slide block slidablely accommodated in a base. The slide block includes a locking tongue. The locking tongue protrudes out of the base or retracts back into the base according to the movement of the slide block. Thus, the locking apparatus can lock the hard disk when the locking tongue protrudes out of the base and unlock the hard disk when the locking tongue retracts back into the base.
