A telescopic structure includes a handle, a main telescopic body, and a telescopic rod assembly disposed between the handle and the main telescopic body. The telescopic rod assembly includes an outer tube and an inner tube group. An end of the outer tube is connected to the handle, the inner tube group is movably disposed inside the outer tube, and an end of the inner tube group is connected to the main telescopic body. A first limiting component is disposed on an outer periphery of the telescopic rod assembly and is configured to limit movement of the inner tube group. A side wall of the telescopic rod assembly defines multiple limiting holes configured to insert the first limiting part. Compared to the related art, it eliminates the need for auxiliary equipment to climb to high places for work, thereby enhancing safety and reliability while also improving work efficiency.
