Retained. Therefore, in this state, it becomes possible to immediately clean the sofa or the wall as a suction tool.

  Next, when the brush 20 is stored or when the extension pipe 13 is connected to the distal end pipe 14, if the finger contact portion 35 of the cover 26 is pressed again, the stopper A39 holding the brush holder 21 is disengaged, The brush holder 21 can be returned to its original position by simply pressing the both side arm portions 42.

Further, since the movable nozzle 18 has an opening through which the extension tube 13 can be inserted without having to store the brush 20 by hand, if the extension tube 13 is inserted along the opening of the movable nozzle 18, the brush holder The extension tube 13 hits the leaf spring 43 provided at the center of the plate 21, and the rear end of the leaf spring 43 pushes up the stopper A 39 of the cover 26 to disengage the engagement. Further, by inserting the extension tube 13 all the way back, the brush holder 21 rotates and is positioned above the tip pipe 14, engages with the rear portion of the stopper A 39, and is positioned and held above the tip pipe 14. Thereby, since most of the brush 20 is stored, it is difficult to touch the brush 20 and the like that are easily soiled in the stored state, and it is hygienic. In addition, there is an aesthetic effect because the dirt is not noticeable.

  Further, the cover 26 covers a gap generated between the brush holder 21 and the tip pipe 14 when the brush holder 21 is positioned at a certain angle α, so that the brush holder 21 is not enlarged and the tip pipe 14 is not enlarged. The communication part 34 can be formed between them, and even if the rotation angle α of the brush holder 21 is increased to widen the cleaning range, the gap can be reduced as much as possible, and a small suction tool having a high suction force can be provided.

  Therefore, it is not necessary to attach or remove the suction tool used when cleaning the sofa or the wall, etc., and it is possible to easily select the use state and the storage state of the suction tool without touching the brush 20 that sucks dust. The usability is remarkably improved, and it is possible to provide a suction tool which is clean and excellent in storage property and excellent in cleaning performance, and can obtain a great effect.

  It goes without saying that the same effect can be obtained even if the suction tool of the present invention is arranged at the tip of the extension tube.

  The configuration of the present invention is not limited to the present embodiment.

  As described above, the suction tool according to the present invention is easy to attach / detach the suction tool (such as a brush) attached to the tip pipe or the like without touching the suction tool, and in the operation of attaching / detaching the extension pipe and the cleaning operation. In addition to being able to store the suction tool, it can be hygienic and improved in usability, so it can be applied not only to household vacuum cleaners but also to commercial vacuum cleaners.
