[0028] The feed port 6 is arranged in a funnel shape to facilitate pouring of materials, and the materials are not easily scattered during the pouring process.

[0029] A receiving port 21 is fixedly connected to the middle of the upper end of the receiving barrel 20. The inner diameter of the receiving port 21 is slightly larger than the outer diameter of the discharge port 12, so as to facilitate the receiving of materials and prevent the materials from being spilled, thereby preventing dust in the air from contaminating furazolidone.

[0030] The support plate 15 is provided with a limiting groove 151 corresponding to the return spring 16 . The return spring 16 is located in the limiting groove 151 , so as to limit the return spring 16 .
