This invention relates to the field of power insulators, specifically to a quick-replacement snap-on insulator that is easy to maintain, comprising an insulator and a cable. The invention utilizes a modular design with two fixed frames (Frame 1 and Frame 2) to divide the insulator's load-bearing structure into independent units. During replacement, the new insulator can be pre-connected to the connecting cylinder of Frame 1 and the snap-on hook of Frame 2, eliminating the need for additional clamps to pre-fix the conductor. The cable tension allows the inclined slide groove to slide along the connecting rod, adjusting the stress point and seamlessly replacing the old and new insulators. This significantly reduces the difficulty and risk of high-altitude operations and shortens operating costs. Simultaneously, through the linkage between the snap-on hook and the trapezoidal cylinder locking rod, when the insulator bears tension, the trapezoidal cylinder and the inner wall of the internally threaded cylinder compress the sphere into the slot for quick locking. The stronger the tension, the greater the locking force, forming a self-locking mechanism. Disassembly allows for quick removal of the old insulator by loosening the internally threaded cylinder, significantly improving connection stability and maintenance convenience.
