The outer tube 2 3 and the inner tube 2 4 are assembled with the connecting tube 5 in the same manner. In addition, when dirt accumulates inside the through groove 9, the knob 2 16 is turned to drive the gear 1103 to rotate. Since the gear 1103 is meshed with the toothed disc 1102, the control rod 1101 is driven to rotate, thereby driving the rotating rod 1001 to rotate, so that the cleaning strip 1002 rotates around the rotating rod 1001, and the end of the cleaning strip 1002 moves inside the through groove 9, thereby scraping off the dirt inside the through groove 9.
