Conducting wire compresses, and increases the fastness of conducting wire.When dismounting, conducting wire, fixed link is pulled to be opened under the action of extension spring, conducting wire
Just it has drawn out.
In addition, insulating bar is insulated telescopic rods, can stretch, it is easy to use.Fluorized marking is set in insulated telescopic rods, side
Just it is identified in the case that night or light are bad.It is coated with insulating layer on collet and insulated telescopic rods, improves insulation performance,
It is safer.The end of the second end of two baffles is respectively provided with arc snap-gauge, and skid resistant course is arranged on snap-gauge, prevents conducting wire and snap-gauge
It skids, increases the contact area with conducting wire, conducting wire is fixed more secured.Several through-holes are set on snap-gauge, increase gas permeability.
The double tongue springs of the utility model setting fix conducting wire, carry out fixed for the first time；Collet both sides are respectively provided with spring
With lower spring, and baffle is set between upper and lower two spring, carry out second it is fixed；Pass through stretching between fixed link and insulating bar
Spring connects, and conducting wire is compressed, and carries out third time and fixes, three layers of fixation, very securely.Effect of the baffle in upper and lower two springs
Under can be with bearing up-down force, and then baffle is upheld to both sides.When installing ground wire, plate washer is stretched out by upward active force to both sides, conducting wire
It passes through, is fixed on wire clamp from centre, when removing ground wire, downward active force is more than the setting value of lower spring, and conducting wire is smooth
In wire clamp out.When conducting wire falls off out of collet, baffle can effectively stop the whereabouts of conducting wire, construct to ensure that
The safety of the personal safety of staff and equipment in journey.The utility model efficiently solves led only by wire clamp fixation in the past
Line, the deficiency being easy to fall off, simple in structure, firm stable, effectively avoid because imperfect earth cause accident there is a phenomenon where.
