The inner support plate, the outer support plate, the chain plate and the pin shaft constitute the drag chain; joints are fixedly connected at both ends of the drag chain; the outer support plate is non-magnetic, and the inner support plate is magnetic, and when the drag chain is laid flat on the support surface, the magnetism of the upper side of all the inner support plates is the same as the magnetism of the upper side of the fixed magnetic sheet.
