When in use, a pressure tube of appropriate length is selected according to the operating height, N unit tubes and N joints are sequentially spliced ​​together to form a rod body, and the pressure tube is placed in the rod body. The operation is very convenient, and the rod body can be disassembled after use, which is convenient to carry. The first connector 5 installs one end of the pressure tube 1 inside the rod body, and the other end of the pressure tube 1 (liquid outlet end) passes through the rod body and the universal tube 2 and cooperates with the second connector 6. The universal tube 2 is arranged between the rod body and the liquid outlet end of the pressure tube 1, which can realize the arbitrary adjustment of the spray angle, thereby reducing the difficulty of the staff's spraying operation. The diameter of the universal tube 2 is substantially the same as that of the unit tube 3. The universal tube 2 is inserted into the unit tube 3 by squeezing the universal tube 2, so that the universal tube 2 and the unit tube 3 are interference-fitted. The liquid inside the pressure tube in this embodiment is not limited to paint or coating, but can also be water, which is used as a cleaning device.

[0019] In this embodiment, if Figure 2 As shown, the two ends of the unit tube 3 are respectively provided with a first external thread 8, and the two ends of the joint 4 are respectively provided with a first internal thread matched with the first external thread 8. The unit tube 3 and the joint 4 are connected by threads, which is convenient for disassembly, and the unit tube 3 can be assembled at will to adjust the length of the rod body.

[0020] In this embodiment, if Figure 2 As shown, the two ends of the pressure pipe 1 are respectively provided with a second external thread, the inner circumferential wall of the first connecting member 5 is provided with a second internal thread matched with the second external thread, and the outer circumferential wall of the first connecting member 5 is provided with a third external thread 7 matched with the first internal thread. The first connecting member 5 is connected to the pressure pipe 1 through the cooperation of the second internal thread and the second external thread, and then connected to the joint 4 through the cooperation of the first internal thread and the third external thread 7.

Each corrugated ring 9 is connected to the corrugated ring 9 on the adjacent side in the manner of inner ring butting against inner ring, and is connected to the corrugated ring 9 on the adjacent other side in the manner of outer ring butting against outer ring. The conical surface of the corrugated ring 9 is an elastic deformation surface. When the conical surface is deformed due to axial pressure, the conical surface flips, and the flipped conical surface flips from the original one side of the outer ring to the other side of the outer ring, and after the pressure is released, the conical surface maintains the flipped state. The metal bellows formed by connecting multiple corrugated rings 9 can be both stretched and bent, and has a shaping force, that is, after the external force that causes the metal bellows to stretch and bend is removed, the metal bellows can maintain the deformed state and withstand a certain axial force and bending force. One end of the bellows is inserted into the unit tube 3, and the bellows' expansion and contraction property makes the bellows abut against the lower end surface of the second connecting member 6. The universal tube 2 can be made of metal or plastic.
