The force area of the entire insulating rod is transferred to the spiral device, greatly reducing the load on the insulating rod and the damage to its own material, improving the shear strength and tensile strength of the insulating rod. According to different voltage standards, the tensile strength of the utility model can stably reach various standard levels such as 40kN, 60kN, 100kN, etc; Moreover, it has little dispersion, which solves the problem of easy fracture of high-voltage switch rods and meets the requirements for tensile strength required on various domestic circuit breakers; At the same time, when covering the joint at the end of the insulating rod, the end of the insulating rod is coated with adhesive, further improving the sealing performance and bonding strength between the joint and the insulating rod, making its performance stable, safe and reliable, and simplifying the assembly process, reducing production costs. Insulation tests need to be conducted every 12 months to ensure the integrity of the insulation rods
