Double wire clamp, as a key device specially designed for the connection of two wires, has emerged as the times require. Double wire clamp is a connecting device used in the field of power lines, communication lines, etc. It is mainly used to fix and connect two wires at the same time, to ensure the relative position stability between the wires, and to provide reliable electrical connection. For example, in overhead transmission lines, double wire clamp can fix two parallel transmission lines together to prevent them from colliding or shifting under the action of wind, vibration, etc.

[0003] Double wire clamp generally has two or more clamping openings, which apply pressure through fastening devices such as bolts and nuts. When the bolt is tightened, the clamping opening tightly clamps the two wires, and the position of the wire is fixed by using friction. This friction must be large enough to resist the displacement force of the wire under the action of external factors such as wind load and icing. However, the existing double wire clamp uses bolts, nuts and other fastening devices to fix the wire, which is time-consuming and labor-intensive, thus reducing the efficiency of fixing the wire.
