When the unloading cover plate 34 is subjected to the impact force of the falling soil, the buffer support plate 33 provides buffer support for the unloading cover plate 34, so that the unloading cover plate 34 can move up and down under the limit of the limit groove 13, so as to achieve the purpose of energy absorption and shock reduction, and effectively protect the connection between the grounding electrode 2 and the conductor rod 4. The length of the buffer support plate 33 is not greater than the length of the rigid support plate 31, and the buffer support plate 33 does not contact the clamping plate 2 12, so it can generate elastic deformation in the radial direction after receiving the pressure of the unloading cover plate 34, so as to absorb energy and reduce shock, and protect the conductor rod 4 and the connection between the conductor rod 4 and the grounding electrode 2. The plate 34 is an arc-shaped plate structure, the limiting groove 13 is a semicircular groove structure, and the inner diameter of the limiting groove 13 is the same as the outer diameter of the unloading cover plate 34, and the vertical distance between the bottom surface of the limiting groove 13 and the bottom surface of the unloading cover plate 34 is not less than 1 cm.
