A positioning device of a lamp rod used in a ceiling lamp of a wire box comprises a retaining seat fixed to a via hole of the wire box and an inserting rod inserted into the retaining seat. An inserting portion exactly passes through the via hole. A top surface of the retaining seat at the inner side of the wire box is a platform which has a through hole and a locking hole. The platform is locked with a limiting unit having a size exactly locking the inserting rod. A top end of the inserting rod has a buckling hole. After the inserting rod has been inserted from the engaging hole of the retaining seat, the buckling hole is exactly buckled with the embedding portion of the positioning rod. Thereby, the inserting rod and the wire box are detachable and thus the space for storage and transfer is reduced.
