[0022] In actual use, in the initial state, the top block 13 is set between the two groups of card blocks 10. At this time, the spring 12 is in a stretched state. The grounding electrode 1 is placed on the ground at the grounding location. The grounding electrode 1 and the grounding electrode top cover 2 are completely knocked into the ground by knocking the plug block 7, and then the plug block 7 is pulled upward. The movement of the plug block 7 causes the top block 13 to be pulled out from between the two groups of card blocks 10 through the pull rope 14. Thereafter, the stretched spring 12 pulls the card block 10 in the direction close to the spring plate 11 under the action of its own elastic force, and finally the card block 10 is pulled out from the card block groove 9 and the card block passing groove 15. Finally, the connecting rod 4 is pulled out of the connecting groove 8, and the grounding down conductor receiving rod 5 is pulled out from the end of the grounding down conductor 6 away from the grounding electrode top cover 2, so that the layout of the grounding electrode 1 can be completed, and there is no need to dig and fill the grounding pit, making the layout of the grounding electrode 1 more time-saving and labor-saving.

[0023] Embodiment 2

[0024] On the basis of Example 1, in order to release the limit between the connecting rod 4 and the connecting groove 8 after the grounding electrode 1 and the grounding electrode top cover 2 are knocked into the ground, the same group of top blocks 13 are arranged between the two groups of clamping blocks 10, and the top block 13 is movably inserted in the cavity of the connecting rod 4, and the top of the pull rope 14 is fixed with a pull rope 14, and the top of the pull rope 14 is fixed to the bottom end of the insertion block 7, and a spring plate 11 is fixed to the bottom end of the groove body of the connecting groove 8, and springs 12 are fixed on the two symmetrical end faces of the spring plate 11, and the other end of the spring 12 is fixed to the surface of the clamping block 10.

[0025] In the initial state, the top block 13 is arranged between the two groups of card blocks 10. At this time, the spring 12 is in a stretched state. When the plug block 7 is lifted upward, the plug block 7 pulls the top block 13 out from the top end of the connecting rod 4 through the pull rope 14, so that the card block 10 is pulled toward the spring plate 11 by the spring 12. Finally, the card block 10 withdraws from the card block groove 9 and the card block through groove 15, and is completely retracted into the cavity of the connecting rod 4, so that the limit between the connecting rod 4 and the connecting groove 8 can be released after the grounding electrode 1 and the grounding electrode top cover 2 are knocked into the ground.

[0026] Embodiment 3

[0027] On the basis of the second embodiment, in order to facilitate knocking the grounding electrode top cover 2 into the ground, a ground breaking cone 3 is fixed to the bottom end of the grounding electrode top cover 2, and the ground breaking cone 3 is a conical object.

[0028] The lower end of the grounding electrode 1 itself is in a pointed cone shape, so the grounding electrode 1 itself can easily pierce the soil layer and be knocked into the ground, and the grounding electrode top cover 2 itself is a cylindrical structure. Therefore, in order to facilitate knocking the grounding electrode top cover 2 into the ground, a breaking cone 3 is arranged at the bottom end of the grounding electrode top cover 2.

[0029] In actual use, in the initial state, the top block 13 is set between the two groups of card blocks 10. At this time, the spring 12 is in a stretched state. The grounding electrode 1 is placed on the ground at the grounding location. The grounding electrode 1 and the grounding electrode top cover 2 are completely knocked into the ground by knocking the plug block 7. Then the plug block 7 is pulled upward. The movement of the plug block 7 causes the top block 13 to be pulled out from between the two groups of card blocks 10 through the pull rope 14. Thereafter, the stretched spring 12 pulls the card block 10 toward the direction close to the spring plate 11 under the action of its own elastic force. Finally, the card block 10 is pulled out of the card block slot 9 and the card block through slot 15. Finally, the connecting rod 4 is pulled out of the connecting slot 8, and the grounding down conductor receiving rod 5 is pulled out of the grounding The down conductor 6 is pulled out from one end of the grounding electrode top cover 2, and the grounding electrode 1 can be laid out without digging and filling the grounding pit, which makes the laying of the grounding electrode 1 more time-saving and labor-saving; the lower end of the grounding electrode 1 itself is in a pointed cone shape, so the grounding electrode 1 itself can easily pierce the soil layer and be knocked into the ground, and the grounding electrode top cover 2 itself is a cylindrical structure, so in order to facilitate the grounding electrode top cover 2 to be knocked into the ground, a breaking cone 3 is arranged at the bottom end of the grounding electrode top cover 2, and the breaking cone 3 is in the shape of a cone as a whole, with the cone tip facing downward, and the cone bottom is the same as the diameter of the grounding electrode top cover 2, so that the bottom end of the breaking cone 3 can also help the grounding electrode top cover 2 to pierce the soil layer and knock the grounding electrode top cover 2 into the ground.
