Technical Field

[0001] The utility model relates to the technical field of near-electricity operations, in particular to a safety traction hook for near-electricity operations. Background Art

[0002] In power construction, especially at high altitudes, construction workers often need to carry tools to perform electrostatic work. In order to ensure the safety of workers when working near electricity at high altitudes, a towing hook is one of the indispensable tools.

[0003] At present, when workers use existing safety towing hooks, when high-altitude workers move up and down on poles or scaffolds, they need to lock the hook of the safety towing hook to the position above the worker's body for fixing. However, most existing towing hooks are fixed in length. Due to the limited length of human arms, high-altitude workers often cannot lock the hook of the safety hook to a high position first. At this time, high-altitude workers can only risk losing insurance or hang the safety hook low to climb the tower, which poses a great safety hazard. Therefore, a safety towing hook for near-electricity operations is urgently needed to solve the above problems. Utility Model Content
