In this way, by arranging the above-mentioned feeding mechanism 60 and exchange mechanism 70, the locking and unlocking device 100 realizes the functions of supplying the nut 2 and discharging, and improves the application range of the locking and unlocking device 100.

When the vibrating disc 62 vibrates out the nut 2 and the nut 2 falls into the receiving hole 6331 (at this time, the lifting rod 635 also supports the nut 2 in the receiving hole 6331), the staggered part 631 drives the bracket 632 to move, so that the receiving hole 6331 is staggered with the output port of the vibrating disc 62, so as to avoid that other nuts 2 on the vibrating disc 62 fall into the receiving hole 6331 again. The lifting part 634 drives the lifting rod 635 to move upward to lift out the nut 2 in the receiving hole 6331, so as to be carried away by the exchange mechanism 70. When the exchange mechanism 70 carries away the nut 2, the lifting part 634 drives the lifting rod 635 to move downward and reset, and the staggered part 631 drives the bracket 632 to move reversely to reset, so that the receiving hole 6331 receives the nut 2 vibrated out by the vibrating disc 62 again.
