摘要： The present invention relates to an extension pipe assembly for a vacuum cleaner. The disclosed extension pipe assembly comprises: a suction pipe including an external pipe and an external power supply pipe which is coupled to the bottom surface of the external pipe, and to the interior of which a movable member is coupled; a flexible pipe including an internal pipe and a power supply pipe attached to the bottom surface of the internal pipe, wherein the flexible pipe is coupled to the suction pipe such that the length of the flexible pipe is adjustable; and length adjustment means joined to the coupling portion between the suction pipe and the flexible pipe so as to lock or unlock the length adjustment function of the flexible pipe and of the suction pipe. The power supply pipe is formed into a single pipe, on both inner walls of which respective conductor plates are formed so as to contact the movable member. When the power supply pipe is inserted into the external power supply pipe, the movable member is inserted into the power supply pipe such that the movable member is movable and contacts the conductor plates to maintain a power supply state.
