Then, make the corresponding clamping block according to the design requirements, open the second mounting hole and the slot on the clamping block, sleeve the insulation sleeve along the middle of the tube body, and sleeve the clamping blocks on the air inlet and outlet interfaces at both ends of the tube body respectively;

[0020] The processing method of the pipe body has simple steps, which can not only effectively improve the processing efficiency of the pipeline, but also is convenient and quick to install and has good stability.

[0021] 2) Processing of the first positioning component and the second positioning component

[0022] a. First, process the corresponding upper and lower positioning blocks according to the size of the tube body, and open arc grooves of matching sizes on the upper and lower positioning blocks, and grind the upper and lower positioning blocks to facilitate clamping and positioning of the tube body and improve assembly accuracy;

[0023] b. Then install the buffer pads in the arc grooves of the upper positioning block and the lower positioning block, and open mounting holes along the sides of the upper positioning block and the lower positioning block.

[0065] b. Then, a buffer pad 15 is installed in the arc groove 14 of the upper positioning block 11 and the lower positioning block 12, and mounting holes are opened along the sides of the upper positioning block 11 and the lower positioning block 12. The buffer pad 15 can reduce the friction between the upper positioning block 11, the lower positioning block 12 and the outer wall of the tube body 1, thereby improving the stability of the connection. The mounting holes are convenient for installing the length adjustment mechanism;

[0066] c. Then, the upper positioning block 11 and the lower positioning block 12 on the processed first positioning component 5 are sleeved on the pipe body 1 and fixedly connected by the first fastening screw 13. The upper positioning block 11 and the lower positioning block 12 on the processed second positioning component 6 are sleeved on the pipe body 1 and pre-fixed by the first fastening screw 13.

When the corresponding gas outlet hole 21 is connected, the gas can be directly output. Only one through hole 19 needs to be opened on the tube body 1, so as to avoid the instability of the strength of the tube body 1 caused by opening multiple through holes 19 on the tube body 1.
