The movable support base 220 can slide above the fixed support base 210, the fixed frame 230 is used for supporting the induction coil 240, the cam 250 can rotate relative to the fixed support base 210, the cam 250 can be driven by a motor, the elastic rod has elasticity and is arranged at the end of the movable support base 220 away from the cam 250. When the round steel section is heated by induction, the round steel section is placed in the induction coil 240 for heating. At this time, the cam 250 can be driven by a motor, so that the cam 250 rotates. When the cam 250 rotates, because the radii of the long and short edges of the cam 250 are different, when the long edge of the cam 250 is in contact with the end surface of the movable support base 220, the cam 250 will resist the movable support base 220, so that the movable support base 220 moves towards the elastic rod. At this time, the elastic rod is compressed and has elasticity, so that the movable support base 220 has a tendency to move towards the cam 250, so that the end of the movable support base 220 is always in contact with the cam 250. Through the interaction of the cam 250 and the elastic rod, the induction coil 240 moves back and forth on the outside of the round steel section to uniformly heat the round steel section.
