[0002] With the development of social economy, the requirements for the power supply continuity and reliability of distribution network lines are becoming higher and higher.

[0003] The wire clamp is used to connect aluminum stranded wires or steel-core aluminum stranded wires with small and medium cross-sections and steel stranded wires of overhead lightning arresters at locations where they are not subjected to tension, and is also used for jumper connections on non-linear pole towers. The existing wire clamps are mainly parallel groove wire clamp structures, which are relatively simple and inconvenient for the installation and positioning of the wire harness. At the same time, after the wire harness is installed, it is easy to detach from the wire clamp, and the stability of the wire clamp connection to the wire harness cannot be well guaranteed;

[0004] In addition, traditional wire clips and wire harnesses are more troublesome to install and do not have the function of pre-positioning during wire harness installation, which is not conducive to the smooth installation of the wire harness.

[0005] Therefore, in order to solve the above technical problems, a new type of wire clamp structure is now needed. Summary of the invention

[0018] A method for using a duckbill type wire clamp structure, the method comprising the following steps:

[0019] Step 1: Assemble the duckbill wire clamp structure; when assembling the duckbill wire clamp structure, it is required to determine the height of the adjustment gasket. At the same time, when the fixed torque nut is installed on the screw, it is required that the fixed torque nut is at the uppermost end of the screw. After the duckbill wire clamp structure is assembled, proceed to the next step;

[0020] Step 2: assembling the wire harness; the wire harness assembly is divided into the first wire harness assembly and the second wire harness assembly.
