Abstract: The present invention relates to a multi-stage pipe fixing structure. If pipes of different diameters are pulled sequentially from neighboring pipes in a state where all the pipes are connected and folded, catching hooks on each of small-diameter pipes are pulled to the outside at the ends of large-diameter pipes, and at the same time, are caught in the reverse direction. On the opposite side of the catching hook, the pipe can be extended with a rigid fixation within a range that does not deviate from a catching protrusion of a fixing socket, and when the small-diameter pipe is moved to the end of the large-diameter pipe which serves as the standard, a slider member on the side of the pipe and which is provided at the end of the pipe is in contact therewith and slides. Because the catching hook is pressed into the inside of the pipe so as to make it possible to push the small-diameter pipe from within the end of the neighboring large-diameter pipe, each multi-stage pipe can be connected and folded by simply inserting one pipe into another pipe safely without directly and manually pressing a button provided on the side of an existing pipe in such a way that the small-diameter pipe is inserted into the inner diameter of the large-diameter pipe.
