[0033] Fourth Embodiment

[0034] As shown Figure 1 and Figure 3As shown in the figure, the lifting assembly 4 includes a hydraulic rod 401 installed on the inner bottom wall of the mounting frame 301.

[0035] Working principle: When in use, the quartz tube is limited by two chucks 102, and then the first motor 101 is started to rotate the quartz tube. The flame nozzle 507 is connected to the gas source, and the flame nozzle 507 sprays flame to heat the quartz tube. As the quartz tube is heated, the quartz tube can gradually expand under the action of centrifugal force, and the limiting rod 509 can push the arc-shaped shell 506 when the quartz tube expands, so that the arc-shaped shell 506 can drive the flame nozzle 507 away from the quartz tube. By starting the hydraulic rod 401, the carrier plate 402 can be pushed to move the water storage box 403 upward. The water storage box 403 drives the roller 404 to move upward to a specified position to limit the expanding diameter of the quartz tube. Then, during the rotation of the roller 404, water can be smeared on the quartz tube, so as to cool the expanded quartz tube. And by starting the power assembly 2, the control assembly 3 can be driven to drive the heating assembly 5 to move to expand the quartz tube comprehensively.
