[0023] Furthermore, a plastic air pipe 102 is sleeved on one end of the air nozzle 4 away from the socket 5, and a pressure gauge 101 and an air switch 103 are provided on the plastic air pipe 102.

Through such a configuration, the connection between the air nozzle 4 and the plastic air pipe 102 is more convenient and stable.

[0024] Among them, it should be supplemented that the first positioning body 2 is provided with a first opening 202, the fairing 7 is located in the first opening 202, the top of the first positioning body 2 is threadedly connected with a first fastening screw 201, the first fastening screw 201 extends into the first opening 202 to position the fairing 7, the second positioning body 3 is provided with a second opening 302, the nozzle 4 is located in the second opening 302, the top of the second positioning body 3 is threadedly connected with a second fastening screw 301, the second fastening screw 301 extends into the second opening 30 2, the air nozzle 4 is positioned in the first positioning body 2, a tail baffle 8 is arranged at one end of the first positioning body 2 away from the fairing 7, which is used to limit the turbine insurance component placed between the fairing 7 and the tail baffle 8, the first positioning body 2 is also provided with a first threaded opening 203, the first threaded opening 203 can be threadedly connected with a first bolt to position the first positioning body 2 on the guide rail 1, and the second positioning body 3 is also provided with a second threaded opening 303, the second threaded opening 303 can be threadedly connected with a second bolt to position the second positioning body 3 on the guide rail 1.

[0025] Through the arrangement and cooperation of the first positioning body 2, the second positioning body 3 and the wind nozzle 4, the second positioning body 3 and the first positioning body 2 can be flexibly and quickly moved and positioned on the guide rail 1, thereby conveniently changing the distance between the wind nozzle 4 and the fairing 7, and the air flow rate flowing into the plastic air pipe 102 can be controlled by the pressure gauge 101, which meets the requirements of the wind speed during the detection process, and the utilization rate of the flowing air is significantly improved.
