A bidirectionally-unlockable lock comprises a lock body, a safety anti-loosening switch and a locking member. The lock body comprises a lock cylinder and a covering layer; one side of the periphery of the lock cylinder is provided with a first hole and a second hole close to two ends respectively; the safety anti-loosening switch is disposed between the lock cylinder and the covering layer and comprises an operating portion and a fastening portion; the operating portion penetrates the covering layer; the fastening portion penetrates into the first hole of the lock cylinder; the locking member comprises a first end and a second end, the first end is used for being inserted into the first hole for catching, and the second end is used for being inserted into the second hole for catching; the first end of the locking member is provided with a positioning portion allowing the fastening portion of the safety anti-loosening switch to penetrate for fastening; therefore, during unlocking of the bidirectionally-unlockable lock, direct loosening of the locking member and the lock body is avoided, and the safety anti-loosening switch can be simply operated as required to separate the locking member and the lock body.
