[0032] Reference Figure 1-5As shown, this embodiment discloses that auxiliary devices 4 are provided on both sides of the protective cover 31, and the protective cover 31 is fixedly connected to the surface of the electrospinning equipment housing 1 with the help of the auxiliary devices 4. The auxiliary device 4 includes two fixed plates 41, and the two fixed plates 41 are respectively fixedly connected to the two sides of the protective cover 31. A positioning rod 42 is fixedly connected to the side of the fixed plate 41 close to the electrospinning equipment housing 1, and a positioning groove 43 is provided at the electrospinning equipment housing 1 corresponding to the positioning rod 42.
