Abstract
The invention, which belongs to the technical field of electrical safety equipment, discloses a mechanical grounding rod comprising a rotating handle and a straight rod. The rotating handle is in an annular shape. One end of the straight rod is in a shape of a pointed cone and the other end of the straight rod is detachably connected with the rotating handle; and spiral line protrusions extending along the axis direction of the straight rod are arranged at the outer side wall, approaching the pointed cone part, of the straight rod. According to the mechanical grounding rod containing the rotating handle and the straight rod is arranged, the rotating handle and the straight rod are connected and the rotating handle is in an annular shape; and the part, not connected with the rotating handle, of the straight rod is in the shape like the pointed cone and the spiral line protrusions are arranged at the outer side wall of one end of the of the pointed cone shape. Therefore, when the grounding rod is driven underground, the worker can buckle the rotating handle and enables the pointed cone part of the straight rod faces the ground; and thus the rotating handle enables the straight rod to be pushed into the ground efficiently. Meanwhile, when the grounding rod needs to be pulled out, the rotating handle is rotated at a reverse direction, so that the grounding rod can be drawn out of the ground in a rotation mode efficiently.
