PROBLEM TO BE SOLVED: To prevent trigger operation by mischief of children or careless liquid jetting. SOLUTION: A shaft hole is formed on a protruding plate section 7 formed along the inner faces of both left and right side walls 6 of a trigger 3; a connecting protrusion 16 is installed so that it protrudes from the rear face of a horizontal plate 13 of a square U-shaped rotating member 11 fitted into between the outer faces of both left and right side walls 6 of the trigger 3; a rotating shaft 15 is installed so that it protrudes from the horizontal plate 13 and is fitted freely rotatably into the shaft hole; and thus, when the connecting protrusion 16 is in the state of being connected to the inner face of the front end of a cylinder 1, then the rear face of the horizontal plate 13 and the front end face of the lower part of the cylinder 1 are connected to each other, making the backward drawing of a trigger 3 impossible and, when the connecting protrusion 16 is in the state of being apart from the cylinder 1, the backward drawing of the trigger 3 becomes possible. |
