The rope-driven telescopic rod is easy to operate and carry.

Description

Technical field [0001] The invention relates to the field of military reconnaissance and surveying, in particular to a rope-driven telescopic pole. Background technique [0002] In the field of military reconnaissance and surveying, when detecting equipment is used for reconnaissance operations, it is often necessary to raise the detecting equipment to a certain height to facilitate the investigation. At present, one of the more widely used methods is to use the telescopic function of the telescopic rod to assist in raising the detection equipment. The existing telescopic rod mainly adopts two methods: one is the hand-held type, which is retracted and extended by human hands. The hand-pull type is suitable for relatively small telescopic rods; the other is the hydraulic control type. The hydraulic control type is suitable for applications where steel is heavy and has a large bearing capacity. It is relatively heavy and depends on equipment to provide power. The operation is compl...

Problems solved by technology

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. The existing telescopic rods mainly adopt two methods: one is the hand-pull type, which is contracted and extended by pulling with both hands. The hand-pull type is suitable for relatively small telescopic rods; the other is the hydraulic control type. The hydraulic control type is suitable for applications where steel is heavy and has a large bearing capacity. It is relatively bulky and powered by equipment, which is cumbersome and inconvenient. carry
