after the lightning rod is installed, the power motor is started in the forward direction, so as to drive the power main shaft and the power auxiliary shaft to rotate, thereby driving the meshing shaft to rotate, driving the main belt wheel to rotate, driving the left fixed rotating shaft to move downwards and be nailed into the ground, transmitting power to the power secondary shaft by the rotating main belt wheel through the power belt, thereby driving the secondary belt wheel to rotate, driving the right fixed rotating shaft to move downwards and nail into the ground, changing the grounding ground resistance at the moment, electrifying the external circuit, so that the external electromagnet is electrified, the left fixed rotating shaft and the right fixed rotating shaft continue to move downwards until the grounding resistance is as large as the selected resistance, the magnetic force of the internal electromagnet and the external electromagnet is the same, the balance slide block returns to the balance position, so that the balance weight moves downwards, the power main shaft is disengaged from the meshing shaft, and the grounding resistance meets the requirement of lightning protection of the building;

the rotating power auxiliary shaft drives the first bevel gear to rotate, thereby driving the second bevel gear to rotate, thereby driving the reversing shaft to rotate, thereby driving the third bevel gear to rotate, thereby driving the fourth bevel gear to rotate, thereby driving the transmission main shaft to rotate, thereby driving the transmission main wheel to rotate, the power transmission of the transmission main wheel is transmitted to the transmission auxiliary wheel through the power belt, thereby driving the transmission auxiliary shaft to rotate, thereby driving the rotation main wheel to rotate, thereby driving the rotation auxiliary wheel to rotate, thereby driving the three-stage sliding sleeve to rotate to the vertical, finally, the height of the lightning rod is adjusted by artificially sliding the one-stage sliding sleeve and the two-stage sliding sleeve, and the lightning rod can be reset by pressing the one-stage key and the two-stage key.
