EJECTOR-GUN

PROBLEM TO BE SOLVED: To provide an ejector-gun capable of sucking and blowing fluids such as water and air, powdery matter such as wheat powder and metallic powder and even solid mater as well, and further provide an ejector-gun capable of changing between the suction side and blow-off side only with a one-touch operation. SOLUTION: An ejector-gun is made to be equipped with an ejector pipe capable of generating ejector effect produced by inserting the leading end of an inserting part of a suction pipe 1 with a gear or spiral groove 3 into a blow-off pipe 5. A socket provided with an arm lever 12 in a sleeve 11 is screwed into this ejector-pipe and coupled to a handle section 15 engaged with a plug to constitute the ejector-gun. The ejector-pipe of the ejector-gun is hold with one hand with one finger catching and pulling the arm lever to make it removable, thus changing the direction of the suction pipe and blow-off pipe by one-touch operation.
