TRIGGER TYPE LIQUID INJECTOR

摘要

PROBLEM TO BE SOLVED: To assemble an automatic lock mechanism returning back to its locked state after releasing of the locked state into a trigger type liquid injection container through a simple structure which is constituted such that a trigger operation is locked by inserting a spacer between a cylinder front end surface and a trigger rear surface. SOLUTION: A spacer 8 is arranged at the extremity end of a leaf spring 7 projected from a lower surface at a rear segment of a cylinder 3 in a forward direction. The spacer is held between a lower segment 3a at a front end surface of the cylinder and a rear surface of a trigger 4 and the spacer 8 is arranged such that it can be released from between the front end surface of the cylinder 3 and the rear surface of the trigger 4 in a downward direction under a rearward retraction of a finger hook plate 9 projected from the lower surface of the spacer 8 toward the lower end of the trigger 4.
