A locking mechanism for a diagonal tie rod in an outward-opening, top-hung hardware system is disclosed. The diagonal tie rod includes a movable tie rod slidably mounted on a base for positioning a first connecting rod. The base has a first connecting rod with a limiting groove at one end near the base. The positioning device includes a limiting block with a locking part. When the window sash needs to be opened to its maximum position, the locking part extends out of the base and engages with the limiting groove to form a limiting connection, thus locking the window sash. The movable tie rod has an unlocking part. When the window sash needs to be closed, the locking part slides within the base driven by the handle. The unlocking part abuts against the limiting block, creating a lever effect that disengages the locking part from the limiting groove, thereby releasing the locked state of the window sash.
