The metal cord 410 may be made of stainless steel, copper, aluminum, or the like. In the present embodiment, the metal cord 410 is a stainless steel cord having excellent corrosion resistance, strength and wear resistance, and the metal cord 410 can be used normally even in various severe environments. In other embodiments, the metal cord 410 may be a galvanized steel wire, which has good weatherability and economy.

The metal cord 410 may be braided from a plurality of wires in a particular manner. For example, the metal cord 410 may be braided by parallel or forward and reverse braiding. In this embodiment, the metal cord 410 is woven by a forward and reverse twisting method, so that the metal cord 410 has high torsion resistance. In other embodiments, the metal cord 410 is woven in a parallel twist, thereby making the manufacture of the metal cord 410 simpler.

The diameter of the metal cord 410 may be designed according to the strength and flexibility required to pull the snow cover 320, for example, when the diameter of the metal cord 410 is small, the metal cord 410 is soft, so that the metal cord 410 is convenient to bend; when the diameter of the metal cord 410 is large, the strength of the metal cord 410 is large, so that the metal cord 410 has good tension performance.

The outer circumference of the metal cord 410 may be subjected to a zinc plating process, which increases oxidation resistance of the metal cord 410, or a special lubricant coating process, which reduces friction loss during sliding of the metal cord 410 in the receiving space 431.

In some embodiments, the protective sleeve 440 may be a silicone sleeve.

In this way, the metal cord 410 can smoothly slide in the receiving space 431, and the thickness of the condensed ice of the moisture, humidity or other liquid accumulated in the gap between the metal cord 410 and the spring fixing tube 430 is relatively thin, which helps the metal cord 410 to rapidly break the ice layer condensed by the moisture, humidity or other liquid when the receiving space 431 is moved, so that the metal cord 410 slides in the receiving space 431.

In some embodiments, the outer diameter of the metal cord 410 is 0.08mm to 0.12mm smaller than the inner diameter of the spring retention tube 430.

In addition, the protective sleeve 440 tightly wraps the spring fixing tube 430, so that corrosion of corrosive substances and pollutants in the external environment to the rope can be prevented, and the service life of the spring fixing tube 430 can be prolonged.

In some embodiments, the shrinkage of the protective sleeve 440 is 0.4-0.6. Wherein the shrinkage of the protective sleeve 440 may be, but is not limited to, 0.4mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, etc. As such, the protective sleeve 440 may have a more suitable shrinkage rate, may more tightly wrap the spring retention tube 430, and provide reliable waterproof protection, thereby more helping to prevent moisture, humidity or other liquids from penetrating the interior of the spring retention tube 430. In addition, the protection sleeve 440 can more tightly wrap the spring fixing tube 430, so that corrosion of corrosive substances and pollutants in the external environment to the rope can be effectively prevented, and the service life of the spring fixing tube 430 is prolonged.

In some embodiments, the outer surface of the metal cord 410 may be provided with a rust-resistant coating. The rust-proof coating can be a zinc coating, and zinc has good corrosion resistance, can form a compact oxide layer and plays a role in preventing metal oxidation and corrosion.

Chrome plating typically covers the outer surface of the metal cord 410 by electroplating; alternatively, the rust inhibitive coating may be a baking varnish coating, which is a special rust inhibitive paint applied to the outer surface of the metal cord 410 and cured by baking to form a protective layer. The baking finish coating may provide good corrosion and oxidation resistance to the metal cord 410.

In some embodiments, cord assembly 30 further includes a teflon tube 420, teflon tube 420 being positioned within receiving space 431, teflon tube 420 being fixedly connected to spring retainer tube 430, e.g., teflon tube 420 may be interference fit or glued to spring retainer tube 430.
