Abstract

An automatic locking keychain includes a curved plate, a pin shaft at one end of the curved plate, a middle seat rotatably arranged on the pin shaft, a fitting block on the middle seat, and a locking mechanism on a side of the curved plate close to the pin shaft. An end side surface of the fitting block away from the middle seat is attached to another end of the curved plate. The locking mechanism is configured to limit a rotation of the middle seat, and includes a limiting hole at an end of the curved plate close to the pin shaft, a sliding rod sliding inside the limiting hole, and a locking shaft at an end of the sliding rod close to the pin shaft. A locking hole is arranged on the middle seat. A spring is provided between the sliding rod and the limiting hole.
