  The cleaning aid of Patent Document 1 has the advantage that the impeller can be rotated by the action of the intake air flowing inside the air passage and does not require a motor or a power source for driving the motor. Since the impeller and the transmission shaft that guides the rotation of the impeller to the tip of the housing are installed in the housing in which the air passage for sucking dust is formed, dust such as sucked hair is collected by the impeller. If it is wound around the transmission shaft, it may cause a failure, so that it is necessary to frequently perform maintenance of the driving unit such as the impeller and the transmission shaft.

  On the other hand, the suction-type hair cutting device of Patent Document 2 has a problem that the cleaning assisting tool of Patent Document 1 has by dividing the air path for rotating the impeller and the air path for sucking the cut hair. It was something to solve. However, if the blade of the clipper is to be replaced at the time of suction by the vacuum cleaner, it is not possible to replace only the blade for safety, and it is necessary to remove the suction-type hair cutting device main body from the vacuum cleaner.

  The present invention has been made to solve the above problems, and does not require a motor, a power source, or the like for a driving unit for driving a mechanism for removing dust, and can reduce the manufacturing cost. It is an object of the present invention to provide a cleaning tool that does not require maintenance of the drive unit and can safely perform replacement work of only the attached attachment even during suction of a vacuum cleaner.
