[0021] In further details, the top cover plate 8 includes a cover plate body 19, and the left and right sides of the cover plate body 19 are fixedly connected with a plug-in board 21, and the front and rear sides of the plug-in board 21 are provided with positioning holes 20. The positioning mechanism 4 includes a fixed shell 15, and the front and rear sides of the top of the fixed shell 15 are provided with a plug-in hole 5, and the front and rear sides of the inner cavity of the fixed shell 15 are movably connected with a connecting slide plate 17, and a positioning spring 18 is fixedly connected between the front and rear connecting slide plates 17, and a movable plug plate 16 is fixedly connected to the side of the connecting slide plate 17 away from the positioning spring 18, and the side of the movable plug plate 16 away from the connecting slide plate 17 penetrates into the inner cavity of the plug-in hole 5.

[0022] A sliding opening is provided on the outside of the fixed shell 15, and the outside of the connecting slide plate 17 penetrates the outside of the sliding opening and is fixedly connected to a push plate. The left side of the housing 1 is fixedly connected to a limit clamp 3, and the surface on the left side of the housing 1 and the right side of the top of the top cover plate 8 are fixedly connected to heat dissipation fins 9. The outsides of the first cooling fan 7 and the second cooling fan 11 are fixedly connected to dust filter screens 6, and the right sides of the bottom of the front and rear sides of the housing 1 are fixedly connected to mounting plates 10.

[0023] During actual manufacturing, when assembling the casing 1 and the top cover plate 8, the personnel insert the plug-in plates 21 on the left and right sides of the cover body 19 into the plug-in holes 5 on the left and right sides respectively.
