On the basis of the original, the inner eight shape was transformed into an 8-shaped shape, and four auxiliary springs were added. While increasing the contact surface, the first semicircle concave shape increased the contact area, and the second semicircle prevented the hanging wire from swinging out, which also increased safety and reliability. The use of springs prevented breakage caused by metal fatigue, increased safety and firmness, and thus the improved ground rod can better protect personal safety when in use. Summary of the invention
