Lower end be respectively arranged with the first through hole being mutually matched, on the left clamping plate and right clamping plate between the first bearing pin and arc-shaped slot
The second through hole being mutually matched is respectively arranged with, also including latch nook and frizzen, one end of the latch nook is by the second pin
Axle is hinged on the upper end of right clamping plate, and the other end is movably set in first through hole, sets in the latch nook side near the second bearing pin
Third through-hole is equipped with, described frizzen one end is hinged in the second through hole of left clamping plate, the other end leads to through the second of right clamping plate
Hole, is movably set in third through-hole.
It is additionally provided with the third through-hole of the latch nook for resisting frizzen free end when the wire clamp is opened
Locating dowel.
The upper end of the left clamping plate and right clamping plate has the fluting worn for insulation operating rope, arranges in the slotted top
There is pulley, the upper end of the latch nook is provided with the fourth hole worn for insulation operating rope.In operating process, insulate operating rope
The enterprising line slip of pulley is set in, insulation operating rope is provide protection against wear.
Compared with prior art, this utility model has advantages below：Earthing clamp of the present utility model passes through latch nook
Return protection, wire is locked, it is ensured that wire clamp and conductive contact firmly, colliding, pull or wind effect under will not also send out
Life comes off, and guarantee electric power overhaul personnel that can be safer carry out field operation, reduces personnel's electric shock risk to greatest extent.
