By designing a connecting mechanism consisting of a limit rod, a spring, and a limit cavity, when the clamp needs to be replaced, the staff applies external force to the two groups of limit rods to make them close and the spring is compressed, so that the limit rod and the limit cavity can be automatically separated to release the fixation, and when installing, the external force is released, and the limit rod can be placed in the limit cavity by relying on the rebound force of the spring to fix the clamp. Although the flip machine can be flipped and clamped conveniently, the welding machine has the risk of not clamping tightly and falling when welding large mass workpieces through spring limit; the clamping plate of the facility has a fixed clamping plate spacing and is only fixed at both ends, so the applicability is low and it cannot be well applied to the workpiece for end welding.
