In actual implementation, the pipe is placed above the roller set 4, and the pipe and the roller set 4 are in dynamic friction. The rotation of the roller body of the roller set 4 can drive the pipe to rotate around its own axis. When the operator rotates the pipe, the roller body of the roller set 4 also rotates with the pipe. The pipe is supported and rotated at the same time, which reduces the force applied to the pipe by the operator and makes the heated part of the pipe uniform, thereby ensuring the bending effect of the pipe. In addition, the heating device 3 is located in the accommodating cavity, and the box separates the heating device 3 and the heated part of the pipe from the outside, which ensures the safety of the processing process.
