Welding seat for metal ultrasonic waves

The welding seat comprises a bottom plate, a lower base is fixedly connected to the center of the top of the bottom plate, vertical rods are fixedly connected to the two sides of the top of the bottomplate correspondingly, and ultrasonic generators are movably connected to the bottoms of the surfaces of the vertical rods; an ultrasonic welding head is fixedly connected to the inner side of the ultrasonic generator, and a baffle is fixedly connected to the top of the vertical rod. The vertical rod moves to the outer side, the vertical rod drives the limiting ring to move in the lower base, atthe moment, the limiting ring moves to drive the connecting block to move, the connecting block drives the sliding sleeve to slide on the surface of the guide column, the reset spring deforms throughmovement of the sliding sleeve, then the metal pipe fitting is installed outside the fixing column, and then the vertical rod is loosened. The limiting ring limits the metal pipe fitting under the condition that the reset sprin
