[0030] Working principle: When using the combustion device, the hydrogen-oxygen mixed gas is led into the interior of the combustion device main body 1 through the connecting pipe 3. The valve 4 is opened, and then it is ignited at the nozzle 2, enabling the combustion device to eject a high-temperature flame, which can well melt the optical glass tube and then weld the optical glass tubes together. When using the support device 5, the U-shaped plate 504 is sleeved on the surface of the combustion device main body 1, and then the U-shaped plate 504 is inserted into the top of the clamping block 503.

Then, manually control the clamping frame 512 to rotate on the surface of the clamping rod 511, so that the clamping frame 512 is sleeved on the surface of the rotating rod 502. Then, pull the moving strip 510 towards the bottom of the rectangular groove 508 through the first spring 516, so that the clamping frame 512 is restricted on the surface of the rotating rod 502, and then the first rectangular block 507 and the second rectangular block 513 are clamped together, so that the nozzle 2 can spray fire in a suitable position, so that the combustion device can be supported when both hands are needed. When using the protection device 6, the first conical sleeve 602 and the second conical sleeve 603 are arranged on the surface of the nozzle 2. Then, manually control the arc plate 607 to rotate on the surface of the round rod 606, so that the arc plate 607 slides into the fixed sleeve 608, and the fixed strip 612 slides into the positioning groove 609 and the interior of the arc plate 607. Pull the fixed strip 612 towards the fixed sleeve 608 through the second spring 611, and then the fixed strip 612 can be well restricted in the positioning groove 609 and the interior of the arc plate 607, so that the first semi-cylindrical barrel 605 and the second semi-cylindrical barrel 604 can be well restricted on the surface of the nozzle 2, so that the melted glass liquid can fall on the first conical sleeve 602 and the second conical sleeve 603, so that the glass liquid can be well received, and thus the glass liquid can be prevented from scalding oneself to a certain extent.
