What is the principle and application of telescopic pole


Unicomposite can provide you the fiberglass telescopic pole made and carbon fiber telescopic pole.

Telescoping pole is usually comprised of a plurality of hollow tubular sections, which are slideably received within each other, thereby allowing the pole to be extended and retracted to various lengths. The extension range, and resulting length, of a telescoping pole is generally based upon the number and length of the individual tubular sections that make up the pole.

A pole comprised of a greater number of sections of equivalent length will extend farther than a similar pole comprised of fewer sections of the same length. In this way, the length of a fully extended telescopic pole may be increased by either increasing the length of the tubular sections, or by increasing the number of sections. Each pair of tubular sections can be described as a receiving section and a received section. The received tubular section fits slideably within the receiving tubular section. The inner diameter of the receiving tubular section is sized equal to, or slightly larger than, the outer diameter of the internally received tubular section.

This internally received tubular section may also be hollow itself and slideably receiving in another internal section which has an outer diameter sized in the same relationship as stated above. In general, this arrangement of internally positioned multiple tubular sections is used to create telescopic poles in a variety of lengths and diameters that are used in a variety of intermittent extension states.

Typically, the length of extension and diameter of the tubular sections is dictated by the pole’s application. Some telescoping poles are used for a specific purpose while in an extended position and are then stored in a retracted position when not in use.


Telescopic poles have and have been used for many purposes, such as golf pickers, photography tripod legs, extended bulb changers, painting or paint pole extensions, connecting different accessories to dust and clean high or deep places.

Telescopic poles are also used in many outdoor recreational activities, using this pole to install tents and awnings. Fishermen find that using telescopic fishing rods helps to reach difficult areas. Similarly, the crew can push the ship vigorously to steer the ship when the water is shallow and the engine or oars cannot be used.

In many places, conventional flagpole arrangements including ropes, pulleys, and chains used to lower or raise the national flag have been replaced by easy-to-use telescopic poles that can complete work faster. The extension rod also makes cleaning the poultry house very convenient and quick.

In addition, there are some special uses, such as radio antenna, solar panel cleaning, blasting, etc.


The length of the telescopic pole can be adjusted according to the height of the user. These have compact sizes, and you can easily put them in a backpack or suitcase or other container.

In addition to the convenience provided by the telescopic pole, the risk of using the telescopic pole is also small. It is safer and more convenient than climbing up from a ladder.
