The interlayer material ensures that the small-diameter pipe and the large-diameter pipe are not bonded, and when the hose bends, the small-diameter pipe and the large-diameter pipe which are not bonded are respectively stretched, so that the softness is ensured. The lead passes through the small-diameter pipe, so that the lead is isolated from the dust channel, the problem of the lead of the corrugated hose can be solved well, and the cost is low.

However, due to the fact that the hardness of the lead is not enough, the traditional manual processing mode consumes long time, the maximum stretching length of the corrugated hose is large, the lead does not have elasticity, and after the lead is repeatedly stretched in the long-time use process, the lead is easily damaged, and further the product fails. In addition, the joint assembly of the corrugated hose needs to be subjected to injection molding at two ends of the hose, and the lead is fixed in the joint, but because the hot melt adhesive is large in injection molding and stamping, the hot melt adhesive is often directly injected into the small-diameter pipe easily, and impact force is generated on the lead, so that the outer skin of the lead is damaged, and the using effect of the dust collector is influenced.
