A locking device for handle assembly with multiple stages wherein a lock member of higher lock may move into the lock hole of the next lower lock for causing a lock pin of the next lower lock to disengage. Further, there is no horizontal component force created on the slope because the lock member of the higher lock inserts into the lock hole of next lower lock as well as higher lock and next lower lock are engaged in a planar surface. This ensures that there is no gap between the higher and next lower lock such that the fully retracted handle grip may rest on the bezel.
