9. A method for using the high-strength combined electric porcelain insulator according to claim 1, characterized in that: The specific steps of the method of use are as follows: S100: Place several insulating ceramic plates at equal distances on the mounting column, and then install the front connector and the rear connector at both ends of the mounting column respectively; S200: When the front connecting member and the rear connecting member are connected to the mounting column, the locking assembly can be controlled to work. When the locking assembly works, the adjustment structure can work and adjust the positions of the No. 1 trapezoidal block and the No. 2 trapezoidal block. The No. 1 trapezoidal block and the No. 2 trapezoidal block are respectively used to resist and limit the insulating ceramic plate, thereby achieving the fixing of the insulating ceramic plate; S300: Finally, the front connector and the rear connector are connected and fixed to the high-voltage line pole to complete the installation and fixation of the porcelain insulator.
