AI Technical Summary

Technical Problem

Existing insulated switch rods mostly adopt a single integral design or a multi-segment fixed splicing structure, with a fixed length, which results in a large space occupation when carried and cannot meet the length requirements of different voltage levels or operating scenarios.

Method used

Design a telescopic insulated switch rod, including a main rod, a first auxiliary rod, and a second auxiliary rod. The three rods are detachable through a connecting ring, a connecting hole, and a limiting bolt. The main rod and the auxiliary rod are fixed by threaded connection and limiting bolt, which can adapt to different length requirements.

Benefits of technology

It allows for easy carrying without taking up too much space, making it convenient to put in the trunk of a vehicle or tool bag, improving work efficiency, adapting to emergency repair scenarios, and ensuring the safety and stability of operation.
