Insulating telescopic extension rope

The utility model provides an insulating telescopic extension rope, including couple, first insulation rope, the insulating rope of second, shell, rotating device, hasp and steel band. The utility model provides an insulating rope of first insulation rope and second has waterproof wear resistant weaving layer through the setting, and effect insulating has completely been realized through setting up insulating rubber coated layer to shell and couple, simultaneously, first insulation rope and the insulating rope of the second becket through setting up the latch closure loop and constructing, shell and couple have the metal level of wear -resisting insulation through the setting, when having guaranteed overall structure intensity, have guaranteed more that the later stage use appears still having insulating property when fatigue damage appears in external insulation rubber coated layer, the condition that winding that the rope appears interweaves has still been stopped to first insulation rope and the insulating
