Puncture wire clamp

The invention discloses a puncture wire clamp. According to the puncture wire clamp, wire clamping grooves are formed by fixed puncture blades and movable puncture blades, wherein the positions of the two fixed puncture blades are changed by adjusting the position of a sliding block in a sliding groove, then, the distance between the two wire clamping grooves is changed, and thus the puncture wire clamp can adapt to main wire and branch wire connection with different separation distances. Meanwhile, the adjustable range of the distance between the two wire clamping grooves is wide, and the puncture wire clamp can adapt to main wire and branch wire connection with large span.
