At this time, the square clamping block 9 is released from the cleaning rod 5. At this time, the square clamping block 9 is pulled to separate the square clamping block 9 from the square clamping groove 8, so that the square clamping block 9 is released from the rotation shaft 4. When the square clamping block 9 slides a distance in the slide groove 7 and separates from the square clamping groove 8, the circular stretching shell 12 is released. At this time, the first spring will contract, so that the clamping block 9 is The positioning rod 6 is inserted into another positioning groove 13 to complete the fixation of the square block 9 and the cleaning rod 5, so that when the rotating shaft 4 rotates, it can only drive the fan blade 20 to rotate, but cannot cause the cleaning rod 5 to rotate, and the cleaning rod 5 will not be separated from the device when passing through the guide rod 30.
