This device effectively achieves the function of adaptively adjusting the distance between the first and second end support components according to the spiral length, and also achieves automated clamping of the spiral to be welded. Furthermore, the device can adaptively adjust according to the diameter and length of the spiral, improving both the clamping stability and the applicability of the device.
