Charger with wire end anti-falling function

The invention discloses a charger with a wire end anti-falling function, and relates to the field of chargers. Aiming at the problem that an existing charger wire and an existing charger head are prone to falling off due to slight stress, the charger of the present invention comprises a charging head, metal inserting pieces and a charging wire, and the two symmetrically-distributed metal insertingpieces are fixedly mounted at one side of the charging head; the other side of the charging head is provided with a jack matched with the end of the charging wire, the side, close to the jack, of thecharging head is fixedly connected with two symmetrically-distributed transverse plates, and an adjusting ring is arranged between the two transverse plates in a sliding and sleeving manner. Two symmetrically-distributed clamping teeth are fixedly connected between the inner walls of the two sides of the adjusting ring, and the two clamping teeth are mounted in the two transverse plates in a sliding manner correspondingly
