[0023] The surface of the bottom plate 1 is rotatably connected with a flap 18. By setting the flap 18, the modulation inductor coil is longitudinally limited, which is beneficial to the stability of the welding process. The bottom surface of the flap 18 is rotatably connected with a support rod 19 movably connected to the bottom plate 1. The shape of the support rod 19 is an inverted T-shape.
