In a specific example, the fixed jaw 1 is provided with a limit pin 12 at the opening side of the locking gib 9, so that the locking gib 9 cannot rotate towards the outside of the occlusion jaw.
It should be noted that the locking clamping strip of the embodiment is prevented from rotating outwards through the limiting pin rod and only can rotate inwards properly, meanwhile, the locking spring can enable the locking clamping strip to return to the original position, when the grounding wire clamp is installed, a clamped equipment lead can be arranged between the locking clamping strip and the occlusion jaw, and when strong wind weather occurs or the lead vibrates, the wiring wire clamp cannot be separated from the equipment lead, so that potential safety hazards are eliminated.
In a specific example, the length of the latching bar 9 is short relative to the entire snap-in jaw spacing.
It should be noted that, in the initial state of this embodiment, there is a sufficient opening distance between the lowest end of the locking clip strip and the movable jaw, which does not affect the removal of the wire clamp, and when the ground wire clamp is hooked on the wire, the locking clip strip does not affect the installation.
When the device is installed and used, an assembled operating rod is connected with a connector 20 of a grounding wire clamp on the ground, the grounding wire clamp is lifted, a fixed jaw 1 is hung at the position of a device lead, then the operating rod is rotated clockwise, a long pin shaft 21 of the connector enters a sleeve transverse groove 27, the force applied when the operating rod is rotated is not enough to rotate a movable locking rod 14 circumferentially due to the action of a damping spring 17, and the movable locking rod 14 keeps the initial state. At this time, no matter what state the elastic locking buckle 15 and the locking groove 16 are, the elastic locking buckle 15 and the locking groove 16 are both in an oblique downward angle, so that the phenomenon of jamming cannot occur, and therefore when the operating lever is pulled, the movable locking lever 14 is subjected to a downward force, the movable locking lever 14 performs force transmission through the steel wire rope 8, and the movable jaw 2 moves towards the fixed jaw 1 along the slide way 5 to be clamped at a wiring position of the movable jaw and the fixed jaw. When the operating rod is rotated clockwise continuously, the long pin shaft 21 gives a force for clockwise rotation of the movable locking rod 14 in the circumferential direction under the limit of the transverse groove 27, so that the elastic locking buckle 15 falls into the latch of the locking groove 16, and at the moment, the baffle 22 plays a limit role, so that the elastic locking buckle 15 is prevented from rotating clockwise in the circumferential direction continuously, the locking state is maintained, the movable locking rod 14 cannot move upwards, and the clamped part is clamped firmly. Then the operating rod is rotated counterclockwise, the long pin shaft 21 of the connector is separated from the sleeve transverse groove 27, the operating rod is taken down, and the installation is finished.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
