Insulating shank of scalable folding

The utility model relates to a steel smelting equipment technical field specifically is an insulating shank of scalable folding, including insulator spindle and hook, the insulator spindle includes first insulation pole, second insulator spindle, third insulator spindle and elasticity bayonet catch mechanism, the outside at the second insulator spindle is established to first insulation pole slip cap, the hook sets firmly the one end at the third insulator spindle, and the other end of third insulator spindle passes through the second hinge and articulates with the second insulator spindle, is equipped with the screw hole on the second insulator spindle, is equipped with the through -hole that corresponds with the screw hole on the third insulator spindle, and third insulator spindle accessible is fixed with the second insulator spindle with the bolt that the screw hole matches. Compared with the prior art, the utility model discloses insulating shank of scalable folding's beneficial effect does: can be convenient folding, flexible and adjust length can enough satisfy the user demand, again portable with deposit.
