[0025] Some preferred / modified embodiments based on the above embodiments will be further described below, and the following embodiments can be selected or combined.
[0026] As shown in the drawings, the locking mechanism comprises a shaft 9, a push button 10 and a spring 11, the push button 10 is fixedly arranged on the shaft 9, the shaft 9 penetrates through the fixing box 6 and is slidably connected with the fixing box 6 and the tightening wheel 5, the spring 11 is sleeved between the push button 10 and the fixing box 6, the shaft 9 is driven to move into the fixing box 6 and the locking hole 8 by pressing the push button 10, and the shaft 9 is reset under the action of the spring 11 when the push button 10 is released. Figures 3-5
[0027] Specifically, the shaft 9 is divided into two sections, the lower section is a spline section, and the upper section is a smooth rod section.
[0028] Further, the inner diameter of the connecting ring 501 and the diameter of the locking hole 8 are the same, and both the connecting ring 501 and the inner wall of the locking hole 8 are provided with a key groove for cooperating with the spline section to lock the tightening wheel 5.
[0029] As shown in Figures 1-2 The fixing belt 4 is fixed on the ventilation pipe 2 through a height adjusting mechanism, the height adjusting mechanism includes a sliding ring 12, a fixed rod 13 and a connecting block 14, the sliding ring 12 is symmetrically arranged on both sides of the ventilation pipe 2, the fixed rod 13 is fixedly arranged on the sliding ring 12, the connecting block 14 is rotatably connected to the fixed rod 13, and the connecting block 14 is connected with the fixing belt 4. The fixing belt 4 can be deflected at multiple angles, adapt to different parts, and facilitate to find a suitable fixing position.
[0030] Further, a pair of symmetrically distributed locking blocks 15 are arranged on the inner side of the sliding ring 12, a sliding groove 16 and a plurality of locking grooves 17 perpendicular to the sliding groove 16 are formed on the ventilation pipe 2, the locking blocks 15 are matched with the sliding groove 16 and the locking groove 17, and the locking blocks 15 are slidably arranged in the sliding groove 16 or the locking groove 17. The locking blocks 15 slide in the sliding groove 16 to adjust the height of the fixing belt 4, and after adjusting to a suitable height, the sliding ring 12 is rotated to make the locking blocks 15 enter the locking grooves 17 to lock the sliding ring 12.
[0031] Further, an inner tube 18 is arranged in the ventilation pipe 2 to ensure the air tightness of the ventilation pipe 2, which is convenient for subsequent operation.
[0032] Specifically, the tightening wheel 5 is provided with a plurality of circumferentially arrayed barbs, and the fixing belt 4 is an elastic rubber belt in close contact with the tightening wheel 5, which can generate a friction force for tightening or releasing the fixing belt 4.
