The lateral limit bolt is inserted into the lateral groove by rotating inward and connected to the elastic extrusion plate.

[0007] Furthermore, in order to improve the lateral storage performance, a lateral sinking hole is provided at the outer opening position of the lateral internal threaded hole.

[0008] Furthermore, in order to improve the firmness and stability of assembly, the cross-section of the longitudinal connecting tube is a regular hexagonal structure, and there is no gap between the outer side surface of the longitudinal connecting tube and the inner connecting surface of the externally threaded ceramic connecting tube.

[0009] Furthermore, in order to improve the lateral insulation performance, the inner end of the lateral limiting bolt is sleeved with a ceramic internal extrusion head for extruding the elastic extrusion sheet.

[0010] The beneficial effect of the present invention is that an insulator iron cap that is easy to install of the present invention uses an externally threaded ceramic connecting tube to thread the top assembly tube to the upper end of the iron cap body, and the height of the top assembly tube is adjusted by rotation to control the lifting and lowering of the lateral loading and unloading port, thereby facilitating installation while improving the limiting capacity of the loading and unloading opening and the anti-falling ability, and using the lateral limiting bolts on the outer side of the iron cap body to limit the bottom limiting ring at the lower end of the longitudinal connecting tube, thereby further improving the firmness and stability of the installed structure.
