The invention provides a wire connection device for electric power communication. The wire connection device comprises a base. A box body is arranged on the top of the base. A threaded rod is rotatably connected to the inner wall of the left side of the box body. The right end of the threaded rod penetrates through the box body and extends to the exterior of the box body. A first rotary handle isarranged on the right end of the threaded rod. The middle part of the threaded rod is connected with the top of the box body through a fixing block. The thread direction of the left segment is opposite to the thread direction of the right segment of the threaded rod. Threaded blocks are in threaded connection with left and right sides of the threaded rod. A sleeve plate is fixedly connected to thefront of each threaded block. Sliding rods which are capable of up-down moving are installed in the sleeve plates. Top ends of the sliding rods penetrate through the box body and extend to the top ofthe box body. Moving plates sleeve the lower parts of the sliding rods. Pressing plates are arranged on the base ends of the sliding rods and are slidably connected with the inner walls of the movingplates. Springs sleeve the sliding rods between the tops of the pressing plates and the upper walls of the moving plates. A groove with an upward opening is arranged in the base. According to the invention, one person is capable of successfully and conveniently carrying out wire connection operation; operation errors are effectively avoided; and working efficiency is greatly improved.
