The first end 605 of the fixed half clip is fixed to the hook 5, and the second end 603 of the fixed half clip is connected to the first end 603 of the movable half clip. One end 103 is hinged. The hinged installation is to make an I-shaped draw-in groove 604 at the second end 603 of the fixed half-clamp, and the first end 103 of the movable half-clamp is hooked into the I-shaped draw-in groove 604, and the I-shaped draw-in groove 604 The fulcrum moves within a certain range. The second end 104 of the movable half clip is equipped with a release mechanism 4, and is connected with the first end 605 of the fixed half clip through the release mechanism 4. The combination of the fixed half-clip 6 and the movable half-clip 1 presents a circular track shape.

There is a certain gap between the inner surface of the second end 603 of the fixed half clip and the outer surface of the first end 103 of the movable half clip, which is the guide wire slot 9 . The grounding ring or bare wire 2 slides into the clamp body from the gap. During the sliding-in process, the second end 603 of the fixed clip half disengages briefly from the first end 103 of the movable clip half.

The second end 603 of the fixed half-clamp and the first end 103 of the movable half-clamp all make sharp angles, and the first end 103 of the movable half-clamp is bent at a certain angle, and then spaced from the second end 603 of the fixed half-clamp A gap is formed at a certain distance.

The fixed half clip 6 includes a first body, a first spring 601, and a first clip 602. One end of the first spring 601 is connected to the first body, and the other end is connected to the first clip 602; the movable The half clip 1 includes a second body, a second spring 101, and a second clip 102, one end of the second spring 101 is connected to the second body, and the other end is connected to the second clip 102; the first body and the second body Constitute the outer edge of the clamp body, the first clip 602 and the second clip 102 are located on the inner side of the clip body, and are arranged mirror-symmetrically, the lower part of the first clip 602 and the second clip 102 are combined and open The mouth 8 is surrounded by a fastening jaw 3 that can accommodate wires. The wires are extruded into the fastening jaw 3 from the lower openings 8 of the first clip 602 and the second clip 102 .

The tripping mechanism 4 includes a tripping operating lever, a limit buckle 402, a steering shaft 405, a tripping spring 406, a docking guide groove 407, an integrated fixing buckle 404, and a tripping down conductor 7. The tripping operating lever It is composed of a first rod 401 and a second rod 403, the first rod 401 is arranged vertically, the second rod 403 is arranged horizontally, and the first rod 401 and the second rod 403 are perpendicular.

The greater the force of fastening the clamp, the tighter the tripping mechanism 4 will be. Therefore, this device can be used for different specifications of wires and grounding rings. Pull the tripping down conductor firmly. 7 can remove the blocking of the tripping mechanism 4, and the tripping down conductor 7 is an insulating rope. The I-shaped slot 604 can ensure that the movable half-clamp and the fixed half-clip 6 are not separated when the grounding wire is removed.

The grounding down conductor 10 is a multi-strand annealed copper wire covered with a soft, high-temperature-resistant transparent insulating sheath, and the wire has good electrical conductivity. The ground electrode 12 adopts a ground nail type ground electrode.

The using method of the present invention is:

The operator puts the hook 5 of the wire clamp on the insulating rod, and uses the insulating rod to slowly approach the grounding device to the wire or the grounding ring, and checks whether the electric testing device 11 reports an alarm. When the line is not charged, align the guide wire slot 9 with the grounding ring or the bare wire 2, and push the insulating rod upward to make the bare wire 2 or the ground ring enter the clamp body through the I-shaped card slot 604 along the guide wire slot 9. At this time, pull down firmly to make the bare wire 2 or the grounding ring enter the fastening clamp 3, and at this time, the hooking of the ground wire clip is completed.

When it is necessary to remove the clamp of the grounding wire, it is only necessary to pull the tripping down conductor 7 forcefully. At this time, the tripping mechanism 4 moves to decompose the clamp head, and slowly releases the tripping down conductor 7 to make the down conductor fall back to the ground. The removal of the ground wire is completed.

The above are only preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the inventive concept, and these all belong to the scope of the present invention. protected range.
