The internally threaded pipe 32 is arranged in the mounting hole of the bottom wall of the frame-shaped air pipe 31. The blowing pipe 34 is arranged in the interior of the cold storage box 1. The outer arc surface upper end of the blowing pipe 34 is threadedly connected with the internally threaded pipe 32 at the corresponding vertical position. The upper end of the blowing pipe 34 is connected with the interior of the frame-shaped air pipe 31. The outer arc surface of the blowing pipe 34 is provided with the cold air hole 35. The cold air is conveyed through the frame-shaped air pipe 31 and the blowing pipe 34 and finally blown out from the cold air hole 35, so that the temperature in the interior of the cold storage box 1 is reduced, and the agricultural products in the interior of the cold storage box 1 are preserved. By changing the connection between the blowing pipe 34 and the internally threaded pipe 32 at different positions, the blowing position of the cold air is changed. The blowing mechanism 3 further comprises a groove 36.

The guide disc 37 is slid in the sliding groove 38, so as to provide guiding support for the movement of the blowing pipe 34. The outer arc surface upper end of the blowing pipe 34 is provided with a limiting disc 4. The limiting disc 4 is arranged in cooperation with the guide disc 37, so as to limit the upward movement range of the blowing pipe 34. The outer arc surface lower end of the blowing pipe 34 is provided with an external thread structure. The external thread structure is threadedly connected with a connecting pipe 5.
