PROBLEM TO BE SOLVED: To provide a superior trigger type liquid injector in which a trigger operation is positively prevented at the time of its non-use, accidental leakage of liquid is prevented, its handling is convenient at the time of its use and its structure is simple. SOLUTION: An oscillating cover plate 13 extended from a nozzle head 11 to a front surface of a trigger 10 and having an engaging plate 15 brought into contact from a side surface to a trigger side surface is arranged such that is turning accompanied by the rotation of the nozzle head 11 can be carried out. Then, at the time of non-use operation, the oscillating cover plate 13 is positioned in front of the trigger to prevent the trigger from being retracted and in turn at the time of its use, the trigger can be drawn under a state in which the oscillating cover plate 13 is turned to the side part and engaged therewith. |
