An interlocking device for controlling clockwise and counterclockwise rotation of a motor is connected with a clockwise rotation module and a counterclockwise rotation module at both ends thereof to form a loop by cooperating with a power-supply terminal and an earth terminal. The clockwise rotation module includes a clockwise rotation trigger switch and a clockwise rotation relay. The counterclockwise rotation module includes a counterclockwise rotation trigger switch and a counterclockwise rotation relay. By such arrangements, the loop collision caused by mis-touch can be avoided by a cross connection of the clockwise and counterclockwise rotation relays with the clockwise and counterclockwise rotation trigger switches, thus preventing the man-made careless mistake and maintaining the smoothness of the operation.
