[0023] As an implementation method in this embodiment, a multi-station mechanism: a group of replacement plates 5 are slidably connected to the slide 101, the length of the replacement plate 5 is less than the length of the slide 101, and two groups of symmetrical mounting holes 500 are provided on a group of replacement plates 5, and two groups of symmetrical receiving grooves 502 are provided on the inner wall of the mounting hole 500, and the receiving grooves 502 are U-shaped structures; the mesh cover 8 is fixed to the mounting hole 500 by a limiting mechanism, and two groups of symmetrical handles 9 are hinged on the outer wall of the mesh cover 8. In order to avoid physical interference, the handle 9 is stored in the receiving groove 502 when it is installed, and in order to facilitate the flipping out of the handle 9, a pull groove 503 is provided on the inner wall of the receiving groove 502 to take out the handle 9.

[0024] As an implementation method in this embodiment, the limiting mechanism is: a positioning groove 501 is provided on the inner wall of the mounting hole 500, and a limiting pin 7 is slidably connected in the positioning groove 501, and the outer end of the limiting pin 7 is hemispherical, a spring 6 is pressed between the limiting pin 7 and the positioning groove 501, and a hemispherical limiting groove 10 matched with the limiting pin 7 is provided on the outer wall of the mesh cover 8.

[0025] As an implementation method in this embodiment, a replacement box 2 is provided next to the plasma fan 4, and a removable box cover 3 is provided at the end of the replacement box 2. Through the above structure, while protecting the mesh cover 8 in the standby state, it also cooperates with the plasma fan 4 to limit the replacement plate 5 in the slide 101.
