[0023] Combination Figure 4 As shown, the welding head fixing seat 4 and the welding head body 5 are an integrated structure, the pressure of the lifting mechanism 3 can be vertically applied to the welding point of the welding head body 5 without deformation of the force arm, the welding head fixing seat 4 can be transformed by 90 degrees and assembled on the movable plate 11, the amplitude rod 6 is connected to the welding head body 5 through the screw rod 8, the amplitude rod 6 and the transducer 7 are tightened in opposite directions through the screw rod 8, and the whole forms a vibration triple group, which is easy to install and disassemble, reduces the processing cost, and flexibly configures the amplitude rod 6 with different ratios. Figure 2 As shown, the welding head fixing seat 4 is located on one side of the frame 2 and is fixedly connected to a movable plate 11. The movable plate 11 moves along the guide rail 13, thereby ensuring the structural stability of the welding head fixing seat 4 when it moves. The frame 2 is located on one side of the movable plate 11 and is fixedly connected to a fixing plate 14 by screws. One side of the fixing plate 14 is fixedly connected to the guide rail 13 by screws.
