Description

technical field [0001] The invention relates to a telescopic dust suction pipe for a vacuum cleaner. Background technique [0002] The telescopic suction pipe is one of the main accessories of the vacuum cleaner. The telescopic suction pipe can change the length of the suction pipe arbitrarily according to the user's needs, so that the user can stand in the most reasonable and comfortable position when using the vacuum cleaner. At present, the telescopic suction pipe used in the vacuum cleaners sold on the market is composed of an inner pipe and an outer pipe that are nested with each other. The inner pipe is provided with a guide groove and a positioning groove, and a needle roller is arranged in the positioning groove. There is a plastic sleeve, and the outer wall of the port of the outer tube is equipped with a locking mechanism that toggles the needle roller to lock the telescopic length of the inner tube. Although the toggle locking mechanisms of various telescopic str...
