Then, the electric telescopic guide rod connecting frame 103 adjusts the position of the position horizontal fine adjustment controller 104 through the electric telescopic guide rod inside it according to the signal control instruction of the PLC controller 5, and makes a fine horizontal adjustment to the stretching control component 10 to ensure that the stretching control component 10 is accurately aligned with the quartz tube after the heat-responsive grooves are formed. Then, the motor in the rotating motor box 105 is started, driving the protective connecting disk 106 to rotate, and the micro electromagnetic guide rod 1014 is energized to apply a driving force to the rack 1012, facilitating the rotation and positioning of the rotating pawl 107 through the linkage of the regulating gear 1011 and the connecting curved rod 109, so that the clamping end 108 of the rotating pawl 107 is docked with the inner edge of the heat-responsive groove on the circumference of the quartz tube, and ensuring the stable gripping of the quartz tube during the stretching process with an appropriate torque. And the protective driving motor 1010 is started, driving the lead screw 1019 to rotate through the gear set 1018, so that under the action of the lead screw 1019 and the guide rod 1091, the force-receiving rod 1016 and the expanding rod 1015 generate relative movement, and the arc-shaped abutting plate 1017 expands outwards to apply a uniform pressure to the quartz tube, ensuring the shape and dimensional accuracy during the stretching process, facilitating the formation of a uniform position movement as the stretching control component 10 cooperates with the sliding saddle 8 and the transverse linear guide 7, so that the quartz tube is stretched in the length direction to form the required size and shape. And then, during the stretching process, the quartz tube enters the guide tube 303 inside the temperature adjustment tank body 301, and the built-in temperature control detection feedback port 302 continuously monitors the temperature in the temperature adjustment tank body 301 and transmits the data to the PLC controller 5 in real time. When the monitored temperature deviates from the set value, the PLC controller 5 adjusts in time according to the deviation magnitude. Then, the guide tube 303 guides the quartz tube during the forming process to move under the action of the above-mentioned stretching control component 10. Then, the PLC controller 5 sends a start signal to the high-temperature resistant driving synchronous motor 306, and the high-temperature resistant driving synchronous motor 306 starts, and the synchronous long rotating shaft rod 307 at its output end rotates accordingly. The rotating teeth 308 on the synchronous long rotating shaft rod 307 mesh with the external tooth ring 309 of the adjustable high-temperature resistant rotating ring 304, and the adjustable high-temperature resistant rotating ring 304 is driven to perform angle adjustment on the side of the guide tube 303 through the rotation of the rotating teeth 308, facilitating the continuous monitoring of the forming state of the quartz tube by multiple groups of photoelectric sensors, so that the guiding edge 3012 can be aligned with the position of the heat-responsive grooves preset on the outer circumference of the quartz tube, and the heat-responsive grooves opened on the outer circumferential surface of the quartz tube are dynamically adjusted by using the guiding edge 3012.That is, when the stretching control component 10 is used to stretch the quartz tube, and the formed quartz tube is too long and causes subsequent deviation, the forming guide component 3 adjusts. After forming alignment and guidance with the stretching control component 10, and then through uniform stretching, then, with the cooperation of the slot 3010 on the inner wall of the high-temperature resistant rotating ring 304, the bottom plate 3014, the return damping spring 3013, and the guiding edge 3012, the thermal stress groove opened on the circumference of the above quartz tube is reinforced. At the same time, the guiding edge 3012 is slidably connected to the thermal stress groove on the circumference of the quartz tube being formed, ensuring the stability and shape accuracy of the quartz tube during the forming process. The formed quartz tube enters the quality inspection end 4 through the other end of the guiding tube 303 for subsequent quality inspection and processing. After that, when the detected quartz tube is stretched and guided to the preset cutting position in the position slot cutting seat 6, the guiding air rod 16 drives the positioning frame 18 to slide and adjust inside the rail groove frame 17. After positioning the position information using the position slot cutting seat 6 and the positioning frame 18, the micro-drilling structure 19 stops at the correct cutting position point of the quartz tube. Then, the micro-drilling structure 19 sequentially performs pre-stress drilling treatment on the cutting points of the quartz tube. Then, the electric lifting rod 14 drives the position laser cutting end 15 to descend above the quartz tube, and the position laser cutting end 15 precisely cuts the quartz tube according to the preset length parameter, ensuring that the length of each section of the quartz tube meets the standard. The cut quartz tube segments automatically slide into the discharge guide groove 12 through the cooperation of the transverse rail 7 and the longitudinal short rail 11 to complete the collection of finished products. The stretching control component 10 with quality deviation drives the stretched and fixed quartz tube to be placed in the storage guide groove on the other side.,
