[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] like Figure 1-3 As shown, an electric grounding device comprises a grounding pile body 1, an inner cavity 2 is arranged in the grounding pile body 1, and four push rods 3 are distributed on the circumference of the inner cavity 2, and the number of the push rods 3 can be adjusted according to actual needs; on the outer wall of the grounding pile body 1, there are distributed storage grooves 4 corresponding to the push rods 3, and a limit column 5 is slidably arranged in the storage groove 4, one end of the push rod 3 passes through the storage groove 4 and is fixedly connected with the limit column 5, and the end of the limit column 5 away from the push rod 3 is a cone, and the setting of the cone structure is to make it easier to save effort when the limit column 5 is inserted into the soil on the ground; a groove 7 is arranged on the top of the grounding pile body 1, and a push column 8 is arranged in the groove 7, and a push column 8 is arranged in the grounding pile body 1 A connecting hole, the two ends of which are respectively connected with the top of the inner cavity 2 and the bottom of the groove 7. A round table 9 which is wide at the top and narrow at the bottom is provided in the inner cavity 2. One end of the push column 8 passes through the connecting hole and is fixedly connected with the round table 9. The outer wall of the push column 8 is provided with an external thread 10. The inner wall of the connecting hole is provided with an internal thread which is threadedly connected with the external thread 10. By rotating the push column 8, the push column 8 can be raised or lowered in the connecting hole. A push block 11 is provided at one end of the push rod 3 away from the limiting column 5. The side of the push block 11 close to the round table 9 is an inclined surface adapted to the outer wall of the round table 9. After the round table 9 is lowered, it can push the push block 11 to move in the direction close to the storage groove 4, thereby pushing the push rod 3 to move.

[0024] The side of the push block 11 away from the truncated cone 9 is connected to the inner wall of the inner cavity 2 through the spring 6. When the grounding pile body 1 is hammered into the ground, vibration will be generated, which will easily cause the limit column 5 to extend out of the storage groove 4, which will increase the difficulty of the grounding pile body 1 being hammered into the ground. The setting of the spring 6 can prevent the limit column 5 from extending out of the storage groove 4, thereby avoiding increasing the difficulty of the grounding pile body 1 being hammered into the ground.

[0025] A rotating rod 12 is provided on the outer wall of the push column 8 away from the truncated table 9. When the soil on the ground is loose, the rotating rod 12 can be directly turned by hand to drive the push column 8 to rotate; a hexagonal hole 13 is provided on the top of the push column 8. When the soil on the ground is firm, a hexagonal hole 13 can be turned with a hexagonal wrench to drive the push column 8 to rotate; a cover body 14 is provided at the groove 7.

[0026] Working principle:

[0027] like Figure 1-3As shown, when the electric grounding device is in use, the grounding pile body 1 is first hammered into the ground, and then the cover body 14 is opened. The rotating rod 12 is turned manually or the hexagonal hole 13 is turned with an inner hexagonal wrench, thereby driving the push column 8 to rotate, so that the push column 8 can be lowered in the connecting hole, and the push column 8 will drive the round table 9 to descend. After descending, the round table 9 can push the push block 11 to move in the direction close to the receiving groove 4, and the push block 11 pushes the push rod 3 to retract into the receiving groove 4, and the push rod 3 will push the limiting column 5 to extend out of the receiving groove 4, and the cone of the limiting column 5 will be inserted into the ground, thereby strengthening the fixation of the grounding pile body 1, increasing the resistance effect on the grounding pile body 1 when it is pulled up, avoiding the grounding pile body 1 from being pulled up by the roots, and greatly reducing the occurrence of safety hazards.
