A bidirectional screw 9 is rotatably mounted on the operating table 1. The bidirectional screw 9 is provided with a forward threaded section 10 and a reverse threaded section 11. The forward threaded section 10 is mounted with a forward nut 12, and the reverse threaded section 11 is mounted with a reverse nut 13. The forward nut 12 is fixedly connected to the upper movable rod 7, and the reverse nut 13 is fixedly connected to the lower movable rod 8. One end of the bidirectional screw 9 is fixedly connected to a turntable 14. The lower surface of the upper movable rod 5 and the upper surface of the lower movable rod 6 are respectively connected to a clamping block 15. When in use, the small tube to be welded is first sleeved on the inner tube fixing rod 3, and the inner support airbag 4 extends into the interior of the small tube. By controlling the valve, the inner support airbag 4 is expanded and clamped and fixed from the inside of the small tube. The number of the inner support airbag 4 can be multiple, so that the inner support airbag 4 can be fixed at different locations inside the small tube, improving the stability of the small tube fixation. The large tube is then placed over the small tube. The bidirectional screw 9 is rotated, driving the upper and lower slides 7 and 8 to move synchronously. The large tube is then secured using the clamping blocks 15. Multiple pairs of clamping blocks 15 can also be provided. Once secured, the large and small tubes are welded using welding equipment. After welding, the bidirectional screw 9 is rotated in the opposite direction, and the valve's internal support airbag 4 is deflated. The welded double-layer quartz tube can then be removed.

[0016] Furthermore, the operating platform 1 is rotatably mounted on the lifting tube 16 via a bearing. The lifting tube 16 is internally threaded with a fixing screw 17 . The lower end of the fixing screw 17 extends out of the lifting tube 16 and is fixedly connected to a base 18 .

[0017] Furthermore, a rotating handle 19 is fixedly connected to the lifting tube 16. The rotating handle 19 can drive the lifting tube 16 to rotate, thereby achieving the lifting and lowering of the lifting tube 16, and then drive the operating platform 1 to rise and fall, and adjust to a suitable height.

[0018] Furthermore, the upper end of the column 2 is fixedly connected to a mounting plate 20, which is provided with a mounting hole for the upper end of the bidirectional screw 9 to pass through, and a bearing is provided in the mounting hole. The upper end of the bidirectional screw 9 passes through the mounting hole and is connected to the turntable 14.

The circumferential surface of the positioning disc 23 is provided with a plurality of evenly spaced vertical slots. A horizontal slide rail 24 is provided on the mounting plate 20. A horizontal slider 25 is mounted on the horizontal slide rail 24. A locking block 26 is fixedly connected to the horizontal slider 25. The locking block 26 has an arc-shaped groove, and a plurality of vertical clips are evenly distributed in the arc-shaped groove. One side of the positioning disc 23 is located in the arc-shaped groove. A plurality of springs 27 are mounted on the mounting plate 20. The horizontal slider 25 is located between the springs 27 and the positioning disc 23. A hand-pull portion 28 is fixedly connected to the horizontal slider 25. By overcoming the elastic force of the springs 27 and pulling the hand-pull portion 28, the locking block 26 is separated from the positioning disc 23, so that the turntable 14 can be rotated freely, driving the bidirectional screw 9 to rotate. Release the hand-pull portion 28, and the locking block 26 is pressed toward the positioning disc 23 under the elastic force of the spring 27. The cooperation of the vertical clip and the vertical clip groove increases the friction between the locking block 26 and the positioning disc 23, so that the positioning disc 23 will not rotate, thereby locking the bidirectional screw 9, and the clamping block 15 can hold the large pipe tightly.

[0020] Furthermore, the clamping block 15 is provided with a clamping groove 29 having an arc-shaped cross section, and the clamping block 15 is made of an elastic material. The clamping block 15 is made of rubber and will not damage the surface of the quartz tube.
