[0060] When in use, first install the battery into the battery box 201, and connect it to each group of electromagnetic generators 203 through wires so that the electromagnetic generators 203 can operate normally. Then, first place the winding drum 4 on the ground and insert it into the soil through the pin 5 to fix the winding drum 4. Then, drive the insulating rod 1 to move upward through the grip rod 101 until the sleeve rod 2 is moved above the cable. Pull the insulating rod 1 downward to drive the sleeve rod 2 to move downward, and the first clamping plate 7 and the second clamping plate 8 are moved above the cable. Then, pull the sleeve rod 2 downward with force so that the cable squeezes the first clamping plate 7 and the second clamping plate 8, separate the first clamping plate 7 and the second clamping plate 8, push the sliding rod 205 to slide in the limiting sleeve 202, and the squeezing spring 207 contracts. At this time, the clamping belt 3 is sleeved on the outside above the cable, and at this time, the clamping belt 3 is pulled in the limiting sleeve 202.

[0061] When the grounding device needs to be disassembled, first hold the handle 101 and press the button 102 to connect the battery box 201 with the electromagnetic generator 203, so that the electromagnetic sheet 2031 generates magnetism. The magnetic force attracts the iron plate 206 on the outside of the slide bar 205, drives the slide bar 205 to move, separates the first clamping plate 7 from the second clamping plate 8, and pulls the clamping belt 3 to separate from the bottom of the cable, then moves the insulating rod 1 and the sleeve rod 2 upward to separate the clamping belt 3 from the top of the cable (while moving, the loosened clamping belt 3 will enter the limit groove 103 as it moves, thereby avoiding pulling during movement), then moves the sleeve rod 2 down from above the cable, pulls the winding drum 4 down from the ground, and rotates the collecting roller 9 to wind up the clamping belt 3, thereby improving the winding effect.
