[0023] like Figure 1 , Figure 5 and Figure 6 As shown, it also includes a clamping mechanism 8, which includes an electric push rod 81, a lifting frame 82, a roller 83 and a second rotating frame 84. The electric push rod 81 is connected to the lower side of the right part of the support frame 1, and the lifting frame 82 is slidably connected to the right side of the support frame 1. The lifting frame 82 is connected to the telescopic end of the electric push rod 81, and the upper part of the lifting frame 82 is rotatably connected to the roller 83.

[0024] When the utility model is in use, the cracking furnace tube is first inserted into the support frame 1, and the left part of the cracking furnace tube is clamped and fixed by the telescopic spring 75 and the clamping frame 74.
