Compared with the prior art, the grounding pin 110 can be supported by the stabilizing member 130 to prevent it from being loosened from the soil connection due to external force, thereby improving the connection stability between the grounding pin 110 and the soil, and avoiding the problem that the grounding pin may be accidentally touched during the maintenance process by the experimenter, resulting in the loosening of the connection between the grounding pin and the soil.

[0028] Combined with Figures 1-3 shown, in this embodiment, the stabilizing member 130 includes a stabilizing plate 131 that slides on the outer wall of the sliding groove 120.
