Grabbing mechanism and damaged cable repairing device

The invention discloses a grabbing mechanism and a damaged cable repairing device. The grabbing mechanism comprises a mechanical claw, a fixed assembly and a movable assembly. Through mutual cooperation of the mechanical claw, the fixing assembly and the moving assembly, the insulation skin can be grabbed and opened when the insulation skin is in a contraction state, and the insulation skin can be conveyed to the damaged position of a cable in a special environment and covers the damaged position of the cable. By means of the damaged cable repairing device, electric quantity loss caused by grounding discharge due to bamboo friction insulation can be reduced, meanwhile, the electric shock risk of personnel is better eradicated, treatment is carried out without power failure, convenience and rapidness are achieved, permanent repairing is carried out after secondary insulation, the power failure frequency is reduced, and the power supply reliability is improved. 本发明公开了一种抓取机构及破损电缆线修复装置，抓取机构包括机械爪、固定组件和移动组件。通过机械爪、固
