A bayonet 305 for installing and connecting the bottom plate 6 is also provided on the lower side wall of the outer shell 3. A wire hole 306 is also provided on the side wall of the lower port of the outer shell 3. The mounting gasket 4 is made of a light guide material. The outer diameter of the brim part of the mounting gasket 4 is the same as the diameter of the circular limiting groove 203 and the height of the brim part is greater than the depth of the limiting groove 203. The diameter of the brim of the mounting gasket 4 is greater than the diameter of the installation through hole 303. A central through hole 401 is provided at the center of the brim part of the mounting gasket 4, and installation through holes 402 that are matched with the fixing stud 101 in terms of quantity and position are also provided around the central through hole 401.
