The second driving bevel gear 832 is a bevel gear, i.e. an angular wheel, and is arranged downwards. Meanwhile, a second driving shaft 82 at the end portion of the rectangular frame 12 is provided with a second driven bevel gear 821. The second driven bevel gear 821 can be engaged with the second driving bevel gear 832. In this application, a distance between the first driven bevel gear 811 and the second driven bevel gear 821 is less than that between the first driving bevel gear 842 and the second driving bevel gear 832, so that a sliding space is provided for the shell, and engagement between different gears can be achieved through sliding up and down. Specifically, when the shell slides to an upper limiting position, the first driving bevel gear 842 is engaged with the first driven bevel gear 811, and at this time, the slide seats can be driven to slide horizontally; and when the shell slides to a lower limiting position, the second driving bevel gear 832 is engaged with the second driven bevel gear 821, at this time, the worm gear and the worm can be driven to rotate, and further the louvers are driven to rotate. An end portion of the lower end of the main shaft 32 is provided with an input end 31. The input end extends out of the shell for connecting a motor or a rocker to serve as a power input end.

[0037] In this application, the support is formed by four section bar cross beams. Each of the cross beams includes a pipe body 9 with a rectangular cross section. Referring to FIG. 8, a vertical separator plate 92 is arranged inside (in the cross section of) the pipe body 9. The vertical separator plate 92 is arranged at one side away from the louvers and divides the interior of the pipe body into a first cavity and a second cavity, where a sectional area of the first cavity is larger than that of the second cavity. The second cavity is internally provided with one or more first horizontal separator plates 91, and the first horizontal separator plates 91 divide the second cavity into a plurality of sub-cavities. An installing portion 93 is arranged on an inner wall of the sub-cavity, and two ends of the installing portion are perforated by a through hole for installing bolts, so as to facilitate the installation of a connecting piece or a cover. The first cavity is internally provided with a second horizontal separator plate 94. The second horizontal separator plate 94 is arranged at a lower position, and divides the first cavity into an upper cavity and a lower cavity, where a sectional area of the upper cavity is larger than that of the lower cavity. The guide rods are installed on an upper surface of the second horizontal separator plate. The slide seats are arranged in the upper cavity and are in slide fit on the guide rods. An opening is formed in a side wall of the upper cavity. An upper end and a lower end of the opening are provided with baffle plates 95, a gap is reserved between the two baffle plates, forming an opening allowing the output shaft of the slide seat to pass through. A bottom surface of the pipe body horizontally extends inwards (in a direction approaching the louvers) and forms a first connecting portion 96. An end portion of the first connecting portion 96 is bent at 90 degrees upwards and forms a second connecting portion 961. The first connecting portion 96, the second connecting portion 961, and the pipe body form an L-shaped trough body for shielding dust and rainwater, so as to prevent the rainwater and dust from falling through the gap, and achieve good usage experience.
