When the electric telescopic rod is used, the lubricating liquid is poured into the inside of the lubricating ring, thereby making the sponge block full of the lubricating liquid, thereby making the surface of the electric telescopic rod evenly coated with the lubricating liquid. In the process of the electric telescopic rod moving up and down, the surface of the electric telescopic rod is coated with the lubricating liquid, thereby causing the electric telescopic rod to absorb dust in the air. Under the action of the cleaning brush and the collection frame, impurities adsorbed on the surface of the electric telescopic rod can be cleaned up, thereby avoiding the electric telescopic rod from getting stuck, thereby achieving the lubrication effect.
