Power wire clamping device

The utility model discloses an electric power wire clamping device which comprises a bottom plate, a first vertical plate, a trapezoidal plate, a sliding rod, an arc-shaped plate, a second vertical plate, a sliding plate, a side plate, a semi-cylinder, a rotating rod, a placing plate, a fastening plate and a side rod. Through the arrangement of the fastening mechanism, after the two attached semi-cylinders are fixed through nuts, the position of the fastening plate is fixed by twisting bolts connected with the fastening plate, then the wire is clamped again, the wire is located between the two clamping devices and is in a suspended state, certain pulling force can be generated at the two ends of the wire, and the wire is clamped again. When the wire is clamped, the rotating shaft rotates to drive the placing plate and the clamping plate to rotate, and the pulling force of the wire on the placing plate is transmitted to the second vertical plate, so that the second vertical plate and the first vertical plate a
