PROBLEM TO BE SOLVED: To wash the inside of a pipe without the sepn. of a hose and a high- pressure washing nozzle by tightening the external threads of a nozzle body into the internal threads of an outer ring to integrate the outer ring and the nozzle body, and further, press fixing the hose by the internal threads of the outer ring and the external threads of the nozzle body. SOLUTION: The hose 10 is screwed into the internal threads B4 of the outer ring 1 down to the end of the internal threads A5 and, in this state, the external threads 6 of the nozzle body 2 are screwed over the entire part into the internal threads A5 of the outer ring 1, accompanying which the external threads 6 presses the hose 10 to the internal threads B4 of the outer ring 1 and press fixes the hose. The high-pressure washing nozzle 3 is constituted by tightening the external threads 6 of the nozzle body 2 into the internal threads A5 of the outer ring 1 to integrate the outer ring 1 and the nozzle body 2 and further connecting the hose 10 with the internal threads B4 and the external threads 6 in the state of pushing the threads to each other, thereby biting the screw threads of both to the hose 10. As a result, the inside of the pipe may be washed without the sepn. of the hose 10 and the high-pressure washing nozzle 3. |
