Because the flow plate 33 is uniformly provided with a plurality of flow holes 331 penetrating through the flow plate 33, and the adjusting plate 34 is uniformly provided with a plurality of adjusting holes 344 penetrating through the adjusting plate 34, when the adjusting plate 34 and the flow plate 33 are at initial positions, the flow holes 331 and the adjusting holes 344 are completely overlapped, and the flow at the moment is at the maximum value, but after the sliding rod 341 is hit, only a part of the flow holes 331 and the adjusting holes 344 are overlapped, so that the flow inside the air duct body 1 is reduced, and the overlap ratio between the flow holes 331 and the adjusting holes 344 is changed according to the degree of hitting the sliding rod 341, so that the flow inside the air duct body 1 is adjusted.
It should be noted that, because the surface of the transmission rod 342 is further wound with the torsion spring 343, and the torsion spring 343 is fixed at the top and bottom of the inner wall of the flow plate 33, after the splicing tube 21 is pulled out, the sliding rod 341 will recover the initial position, so as to be convenient for the next use, and further, on the basis of preliminarily fixing and sealing the splicing tube 21, the splicing tube 21 can adjust the flow rate inside the air duct body 1, wherein, when the first-stage platform 211 abuts against the third arc-shaped block 313, the fixing effect of the splicing tube 21 is better than that when the first-stage platform 211 abuts against the second arc-shaped block 312, and thus, when the first-stage platform 211 abuts against the third arc-shaped block 313, the sealing block 12 on the air duct body 1 can be inserted deeper into the sealing sleeve 22 on the splicing tube 21, and compared with that when the first-stage platform 211 abuts against the second arc-shaped block 311, the sealing effect on the spliced tube 21 is good.
