| Zusammenfassung: | The invention discloses a key chain, which comprises a C-shaped component of which the upper end is provided with an upper buckle matched with a spring. The key chain is characterized in that the lower end of the upper buckle and the lower end of the C-shaped component are provided with two magnets of which the opposite surfaces are opposite in polarity. According to the key chain, the connection strength at a port of the key chain can be strengthened under the action of the magnets, so that the key chain is prevented from loosening. |
