However, this is because the respective injection nozzles are rotated integrally by revolving the ring-shaped connecting wire, so that the configuration is complicated and the installation cost is greatly consumed and the operation is troublesome. Also, since each injection nozzle can not be controlled individually, do.

In order to solve such a problem, the "multi-type spray nozzle actuating device for a fountain block" of the Japanese Patent Registration No. 10-1115824 is provided with a rotary device for rotating the spray nozzle, and the spray nozzle body is operated by a universal type A multi-type spray nozzle actuating device for a fountain block is provided which is rotatable in an arbitrary direction on a device. This is because the injection nozzle body equipped with the injection nozzle is installed inside the nozzle body housing, and the nozzle body housing including the injection nozzle is moved in the X-axis (front-back) direction by the X-axis actuator unit forming the universal- (Left and right) direction by a Y-axis actuating device so as to rotate the injection nozzle body in which the injection nozzle is mounted in an arbitrary direction forward, backward and leftward. However, such a spray nozzle operating apparatus requires sealing for improving the waterproof function by applying a large number of coaxial couplings of the driving unit and the piping, and it is difficult to assemble due to the complicated structure, and it is difficult to secure quality and reliability.
