The utility model discloses a wire clamp base, which comprises a long strip-shaped lower clamp base and two upper cover plates. A lower semicircular slot is formed at each end of the lower clamp base. An upper semicircular slot is formed at the bottom of each upper cover plate, the upper cover plates are covered on the lower semicircular slots at two ends of the lower clamp base through bolts respectively, and the upper semicircular slots of the upper cover plate and the lower semicircular slots of the lower clamp base are in opposite joint to form entire circuit holes. The wire clamp base has simple structure, assembles the lower clamp base and the upper cover plates with bolts, and is easy for installation and routine maintenance. The oppositely jointed semicircular slots can effectively clamp the wire, and the tightness of the wire clamp base can be adjusted through the bolts to adapt to the wires with different diameters. The parallel use of a plurality of wire clamp bases can effectively ensure the smoothness of two parallel wires.
