[0002] In the existing technology, a pin breaker for live transmission line operations is a special tool used for safely cutting off and connecting a transmission line during live operation. However, since live transmission line operations are often carried out in high-altitude environments, the handle of the pin head may need to be replaced to adapt to different operation requirements. However, there are some problems with the installation and disassembly of existing pin breakers, which affect their usability.

[0003] First of all, the existing pin breakers for live transmission line operations may require complex operation steps when installing and disassembling the handle of the pin head. Due to the design and structure of the pin breaker, replacing the handle may require special tools or skills, which increases the difficulty and time of operation. This inconvenient installation and disassembly method may affect the progress of the operation and reduce work efficiency.

Due to the high-altitude characteristics of the live transmission line operation environment, operators need to work at high altitudes. If the installation and disassembly of the pin breaker are not stable or improper, the handle may fall off or be damaged, leading to safety accidents. Such safety hazards not only threaten the safety of operators but also may cause equipment damage and operation failure. Summary of the Utility Model
