Therefore, in order to eliminate such a drawback, as a safety device, a nozzle fitting cylinder fitted to the front end of the injection cylinder and the nozzle fitting cylinder are used. With the nozzle head fitted to the front of the fitting tube,
When the first half and the second half of the liquid discharge path are separately provided, and the nozzle head is rotated with respect to the nozzle fitting cylinder, the first half and the second half of the liquid discharge path communicate with each other, and are further rotated or reversed. It is practiced that the rotation interrupts the communication between the front half and the rear half.

た。As described above, even in the liquid ejector provided so as to open and close the liquid discharge path by rotating the nozzle head with respect to the nozzle fitting tube, the liquid discharge path remains closed. When the trigger is pulled frequently, the trigger bends and resiliently restores, so that the plunger retreats and moves forward a little. The high-pressure liquid may be stored in the front part of the injection cylinder between the liquid discharge path part formed by the nozzle fitting cylinder and the like, and when this occurs, when the nozzle head is turned to the liquid discharge path communication position, The high-pressure liquid stored in the front part of the injection cylinder spouted from the nozzle hole regardless of the trigger operation. Further, if the trigger is strongly pulled, the nozzle head may come off from the nozzle fitting cylinder due to the high pressure in the injection cylinder.
