The invention relates to the technical field of locks and discloses an actuator assembly of a combination lock. The actuator assembly includes a fixed motor, a drive shaft fixed to the axis of the motor, a cylindrical spring sheathed on the drive shaft and displaceable axially, a pin installed onto the drive shaft which may screw within two adjacent loops of the cylindrical spring, and a casing installed coaxially with the motor. The casing includes a cavity for accommodating the cylindrical spring, and a second sliding groove formed on the casing, and both ends of the cylindrical spring have a retaining ring extended outwardly from the outer periphery of the cylindrical spring and the retaining ring disposed at the second sliding groove for preventing the rotation of the cylindrical spring.
