Form a arch 632 between two adjacent draw-in grooves 631 of driving medium 63, this arch 632 butts respectively in two fixture blocks 41 along the both sides of first operation pipe 4 circumference, and this arch 632 butts in the stopper along the axial side of first operation pipe 4 for arch 632 has all obtained fine spacing in three orientation, and is fixed effectual, thereby guarantees the stability of being connected between first operation pipe 4 and the driving medium 63.

In order to facilitate the operator to perform the rotating operation, as shown in fig. 2-3, the ground rod 100 further includes a connecting pipe 10 and a second operating pipe 14, the connecting pipe 10 is made of an insulating material, preferably plastic, the connecting pipe 10 is sleeved outside the screw 5 and connected thereto, and the connecting pipe 10 plays a role in intermediate connection and extension. The second operation pipe 14 is sleeved outside the connection pipe 10 and connected to the screw 5, and the second operation pipe 14 and the first operation pipe 4 are configured to rotate in opposite directions. In practical use, the first operating tube 4 and the second operating tube 14 are respectively held by two hands of an operator, so that the screw 5 can be conveniently screwed, the screwing stroke of the screw 5 is larger, the time of the operator is saved, and the labor intensity is reduced.

Optionally, the positioning ring 15 is sleeved outside the connecting pipe 10, the positioning ring 15 is located between the connecting pipe 10 and the second operating pipe 14, the working principle of the positioning ring 15 is the same as that of the positioning ring 9, the bending of the connecting pipe 10 in the moving process is reduced, and the using effect is guaranteed.

The working process of the ground rod 100 provided by the embodiment is as follows:

in the actual use process, the operator respectively holds the first operating tube 4 and the second operating tube 14 with two hands and rotates the first operating tube 4 and the second operating tube 14 in opposite rotation directions, the transmission member 63 slides along the sliding groove 611 of the spinning seat 61 under the driving of the first operating tube 4, when the transmission member 63 slides into the escape groove 621 of the pressing block 62, the pressing block 62 moves toward the screw 5 and along the radial direction of the screw 5, the pressing block 62 gradually compresses the elastic member 64, the pressing block 62 is abutted against the thread section of the screw 5 and is engaged, so that the first operating pipe 4, the transmission part 63, the pressing block 62 and the screw 5 are sequentially connected in a transmission manner, the first operating pipe 4 and the second operating pipe 14 are continuously operated to rotate, the screw 5 and the pressing block 62 are equivalent to a screw-nut pair, the screw 5 rotates along the self axial direction, can also move along the axis of the crimping component 2, so that the crimping piece 21 of the crimping component 2 is abutted with the lead;

if the wire needs to be separated, when the first operating tube 4 and the second operating tube 14 are operated to respectively rotate reversely, the transmission member 63 is driven by the first operating tube 4 to slide reversely along the sliding groove 611 of the spinning seat 61, when the transmission member 63 slides through the avoiding groove 621 of the pressing block 62, the transmission member 63 does not press against the pressing block 62 and is separated from the pressing block 62, the compressed elastic member 64 pushes the pressing block 62 to move in the direction away from the screw 5 under the self-restoring acting force, so that the pressing block 62 is separated from the screw 5, and the transmission connection among the first operating tube 4, the transmission member 63, the pressing block 62 and the screw 5 is interrupted. Then, the first operating handle is moved downwards to drive the spinning seat 61, the insulating inner tube 8, the screw 5, the connecting shaft 7 and the crimping component 2 to move towards the direction far away from the hook member 1, so that the hook 11 of the hook member 1 is opened, and the lead is conveniently separated from the hook member 1.
