In this embodiment, the first rotating disc 1031 and the second rotating disc 1032 are arranged, so that the ground wire 104 can be wound in the accommodating groove, and the first rotating disc 1031 and the second rotating disc 1032 are arranged to be matched with the bayonet 105, so that a certain angle of rotation of the rotating disc 103 can be adjusted at any time, and the extension lengths of the conductor ends 1041 and the grounding ends 1042 at the two ends of the ground wire 104 relative to the rotating disc 103 can be controlled conveniently.

Further, as shown in fig. 6, the grounding wire device provided in this embodiment further includes a first positioning element 106 and a second positioning element 107, the first positioning element 106 and the second positioning element 107 are respectively disposed at the ends of two ends of the grounding wire 104, the width of the first positioning element 106 is greater than the width of the first opening 1001, and the width of the second positioning element 107 is greater than the width of the second opening 1002. By arranging the first positioning part 106 and the second positioning part 107, when the coil spring 102 is restored, the conductor end 1041 and the grounding end 1042 at the two ends of the grounding wire 104 are both rolled into the accommodating groove, that is, the conductor end 1041 and the grounding end 1042 are both received into the wire box 100, so that when the rolling mechanism is not used again, the conductor end 1041 is connected with the grounding terminal on the connecting rod 13.

The use process of the grounding wire device provided by the embodiment is as follows:

when the winding mechanism is used, the conductor end 1041 and the ground end 1042 of the winding mechanism are respectively pulled out of the accommodating groove, and after the conductor end 1041 and the ground end 1042 are pulled to a proper distance, the bayonet lock 105 is inserted between the two adjacent limiting blocks 1034 to limit the rotation of the rotating disc 103. Conductor end 1041 is connected to the ground terminal on connecting rod 13 and ground terminal 1042 is grounded, at which time, rotating disc 103 rotates to place coil spring 102 in a stored energy state. Starting a control button on the handle 4, starting the motor to rotate the gear 61, simultaneously rotating the gear teeth 131 meshed with the gear 61, further rotating the chuck 1 relative to the handle 4 by a certain angle to adapt to busbars in different arrangement modes, and after the angle between the chuck 1 and the handle 4 is adjusted, closing the control button and stopping the rotation of the motor. The knob 8 is rotated to pull the pull rope 5, the pull rope 5 pulls the second telescopic arm 32, the second telescopic arm 32 drives the movable press plate 2 to move, so that the movable press plate 2 moves towards the lower chuck 12, the second telescopic arm 32 retracts into the first telescopic arm 31, the distance between the upper chuck 11 and the movable press plate 2 is increased, the bus bar is conveniently placed between the upper chuck 11 and the movable press plate 2, when the movable press plate 2 moves towards the lower chuck 12, the spring 33 stores energy due to the contraction, after the bus bar is positioned between the upper chuck 11 and the movable pressing plate 2, the pulling rope 5 is released, the second telescopic arm 32 is in a free state because the second telescopic arm is not pulled by the pulling rope 5, the spring 33 drives the movable pressing plate 2 to move towards the upper chuck 11 because the elastic deformation is recovered, so that the distance between the upper chuck 11 and the movable pressing plate 2 is reduced, the second telescopic arm 32 extends out of the first telescopic arm 31, and meanwhile, the upper chuck 11 and the movable pressing plate 2 clamp the busbar. When the chuck 1 is taken down, the pull rope 5 is pulled to enable the movable pressing plate 2 to move towards the lower chuck 12, the distance between the upper chuck 11 and the movable pressing plate 2 is increased, the chuck 1 is taken down from the bus bar, and then the pull rope 5 is released. Finally, the conductor end 1041 is separated from the ground terminal, the bayonet pin 105 is separated from between the two stoppers 1034, and the rotary disk 103 winds the ground wire 104 into the accommodating groove under the action of the coil spring 102.
