AI Technical Summary
Existing grounding devices are prone to loosening after installation, and the threaded posts agitate the soil during rotation, making it difficult to provide strong grip and resulting in insufficient stability.
The device uses a motor-driven sleeve to rotate, which in turn drives the connecting column and drill bit to drill holes. Combined with a motor-driven turntable, it inserts a fixed pile. The threaded rod and drill bit design ensure that the device is stable on the ground in both horizontal and vertical directions.
The improved grounding device grip prevents the device from swaying in the horizontal and vertical directions, ensuring stability and durability during use.
