The utility model discloses a turnover box for verifying mutual inductors on an automatic production line. The turnover box comprises a case body, wherein a mutual inductor bracket is arranged in the case body; and at least one mutual inductor clamping part matched with the mutual inductors is arranged on the mutual inductor bracket. According to the turnover box, the mutual inductor bracket for clamping the mutual inductors is arranged in the case body, so that the mutual inductor cannot be mutually collided in the turnover transportation process, and the completeness of the mutual inductors in the turnover transportation process is ensured; and the turnover box cannot slide and is difficult to collapse in the superposition process through additionally-arranged clamping grooves and clamping blocks. The turnover box is suitable for the turnover of the mutual inductors.
