The metal frame 14 is fixedly connected to the right end inside the shell 12.
[0021] The air outlet cover body 13 includes a connecting shell 131, a shielding frame 132, a metal plug 133, a connecting piece 134, a threaded rod 135 and a limiting plug 136. The shielding frame 132 is inserted into the right end of the connecting shell 131, and the connecting shell 131 is movably connected to the right end of the shell 12. The connecting shell 131 and the shell 12 are movably connected, and then the limiting plug 136 is inserted into the connection between the shell 12 and the connecting shell 131, and the limiting plug 136 and the shell 12 can be limited and fixed. The threaded rod 135 is fixedly connected to the left end of the connecting shell 131, and the limiting plug 136 is movably connected to the surface of the threaded rod 135. The surface of the threaded rod 135 rotates the nut, and the nut can thread the limiting plug 136 and the threaded rod 135 to fix the position of the limiting plug 136. The threaded rod 135 is inserted into the right end of the connecting shell 131, and a nut is rotatably connected to the surface of the threaded rod 135. The nut and the threaded rod 135 can threadably fix the connecting shell 131 and the shielding frame 132, which is convenient for disassembling and replacing the shielding frame 132.
