Special-shape parallel groove clamp

The utility model discloses a special-shape parallel groove clamp which comprises The parallel groove clamp structurally comprises a wire clamp body, a cover plate and a bolt. A wire-pressing contact surface, namely groove surfaces of the cover plate and the wire clamp body, is changed into tooth-shaped, thereby increasing static friction and reducing loss caused by sliding friction. A contact surface between the cover plate and the wire clamp body is recessed at one side and protruded at the other side. Thus, the cover plate is combined with the wire clamp body more tightly, the relative sliding is reduced, sliding wearing is avoided, and the special-shape parallel groove clamp has advantages compared with a present parallel groove clamp.
