The first vertical edge trimming rib 341 is perpendicular to the horizontal plane, with a length of about 30 mm. The upper end of the first vertical edge trimming rib 341 is vertically connected to the left end of the upper plane rib 343; the left end of the upper plane rib 343 is vertically connected to the upper end of the first vertical edge trimming rib 341, and the right end is vertically connected to the upper end of the second vertical edge trimming rib 342, with a length of about 6.3 mm; the length of the second vertical edge trimming rib 342 is about 22.8 mm, the upper end is vertically connected to the right end of the upper plane rib 343, and the lower end is parallel to the lower end of the first vertical edge trimming rib 341, with a distance of about 7.3 mm; the connecting rib 344 is parallel to the upper plane rib 343, with a distance of about 13.3 mm between them, the left end of the connecting rib 344 is vertically connected to the inner side of the first vertical edge trimming rib 341, and the right end of the connecting rib 344 is vertically connected to the left side of the second vertical edge trimming rib 342. The first trimming vertical rib 341, the connecting rib 344 and the second trimming vertical rib 342 form a downward second opening 345, and the second trimming vertical rib 342 is about 7.3 mm shorter than the first trimming vertical rib 341. The function of the opening is to guide and facilitate the hanging and installation of the lower fixed seat - the trimming strip 34 and the trimming strip hanging rib 324 of the second base 31.

[0078] Furthermore, both ends of the first base 11 and the second base 31 are respectively provided with decorative heads 35. It can be understood that a good decorative effect can be achieved while also achieving a good blocking effect.

[0079] Furthermore, a strong current line or a weak current line is arranged on the first base 11 .
