The inner wall of the main body 11 facing the inner shell 2 is also provided with positioning ribs 114 for positioning the dustproof pad 14, so as to facilitate the quick installation of the dustproof pad 14.

[0029] refer to Figures 5 to 6 As shown, the inner shell 2 has a top wall 21, left and right side walls 22, a rear wall 23, and a partition 24 extending horizontally from the rear wall 23 toward the rear cover 13. The partition 24 divides the receiving space of the rear wall 23 toward the rear cover 13 into an upper space 231 above the partition 24 and a lower space 232 below the partition 24. The height of the upper space 231 is greater than the height of the lower space 232. The left and right sides of the upper space 231 are basically unobstructed, while the left and right sides of the lower space 232 have partial structures of the side walls 22.
