Description

Rope Driven Telescoping Pole

technical field

The utility model relates to the field of military reconnaissance and surveying, in particular to a rope-driven telescopic rod.

Background technique

In the field of military reconnaissance and reconnaissance, when using detection equipment for reconnaissance operations, it is often necessary to raise the detection equipment to a certain height for easy reconnaissance. At present, one of the most widely used methods is to use the telescopic function of the telescopic rod to assist in raising the detection equipment.
