A connecting port configured to prevent twisting of a hose (2) on an atomizer (1) for spraying pesticide, characterized in that it comprises: a fastening part (11) at a lower part to be fastened and fixed to the hose (2) And a protruding portion 12 having a groove 13 at an end thereof and protruding from the protruding portion 12 and having a connecting portion 11 and a connecting tube 10 )； A rotating tubular body 20 provided on the protruding portion 12 of the connection tube 10 and having a through hole 22 so as to be rotatable and having a fixing washer 21 so as not to be detached from the groove 13； The protruding portion 12 of the coupling tube 10 or the through hole 22 of the rotating tube 20 is inserted into the connecting portion of the connection tube 10 and the rotary tube 20 so as to prevent the pesticide from flowing out A packing means (30) having an O-ring (23) for preventing the pesticide from flowing out； A fixed tubular body 40 fastened to an upper portion of the rotary tubular body 20 and fixedly connected to the sprayer 1 and having a flow hole 41 through which the pesticide flows from the hose 2； And inserted into the protruding portion 12 of the coupling tube 10 to be mounted on the upper portion of the rotating tube 20 and inserted on the protruding portion 12 to prevent damage due to friction and water pressure, (50) having a rotating ring (51) for preventing friction by the rotating ring (51). Accordingly, the present invention provides an effect of preventing the twisting of the hose while reducing the burden on the consumer, because it can be used for a long period of time by being protected from pressure and water pressure generated by the rotating friction between the connecting tube body and the rotary tube body, and can be used for a long time.본 발명은 농약을 분사하는 분무기(1) 상에 호스(2)의 꼬임이 방지하도록 구성된 연결구에 있어서: 상기 호스(2)와 체결 고정되게 하부에 체결부(11)를 구비하고, 상부에 일체로 돌출 형성되면서 끝단에 요홈(13)을 구비하는 돌출부(12)를 구비하며, 내부에 체결부(11)와 돌출부(12)의 농약이 유동되게 유로홈(14)을 구비하는 연결관체(10)
