[0044] The use method of the bending device for power tube processing provided in the embodiment includes the following steps:

[0045] A: Before the power tube bending processing, the positions of the two rotating wheel assemblies 2 are adjusted according to the bending angle of the power tube, first, the installation base 201 is installed in the adjusting installation groove 4, so that the first threaded hole 401 and the second threaded hole 2011 are aligned, then the installation base 201 is fixed in the adjusting installation groove 4 by using the bolt 5, then the other rotating wheel assembly 2 is installed in the symmetrical adjusting installation groove 4, and the two rotating wheel assemblies 2 are adjusted and installed;
