The invention relates to a shape memory alloy locking device, belongs to the field of mechanical locks, and solves the problems that a traditional shape memory alloy locking device is numerous and jumbled in structure and cannot be repeatedly used. The locking device comprises an upper shell and a lower shell, the upper shell and the lower shell are assembled together to define an internal working space, a friction plate is rotatably arranged in the working space, the locking device further comprises a limiting plate and a limiting plate control piece, the limiting plate is arranged between the friction plate and the upper shell, and the limiting plate control piece is arranged between the friction plate and the upper shell. The limiting plate control piece is made of shape memory alloy, the shape memory alloy stretches out and draws back to control the limiting plate to move up and down, and therefore the friction plate is unlocked and locked through the limiting plate. The locking device is simple and compact in structure and can be repeatedly used.
