Specifically, the housing 111 can be a metal housing or a plastic housing, for example, if it is made of metal, aluminum alloy, metal aluminum or stainless steel can be used. If the shell is made of plastic, PC (polycarbonate) or acrylic can be used.

A first baffle 112 is disposed on the first main body 11 , and the first baffle 112 is disposed within a distance between the first main body 11 and the second main body 12 . In this embodiment, the first baffle 112 is an arc-shaped plate structure. The first baffle 112 is used to limit the rotation angle of the bending chain 13 so as to realize the opening and closing angle between the first body 11 and the second body 12 when the bending chain 13 rotates to When the angle is 0 degrees, the bending chain 13 can maintain the arc-shaped structure formed by its rotation. It can be understood that the first baffle 112 is two pieces, which are respectively arranged on two ends of the first main body 11 .

Further, the first main body 11 includes two opposite connection ends 113 , and the first baffle 112 is disposed on the connection ends 113 .

At this time, the first baffle 112 and the second baffle 121 are arranged side by side and facing each other.

Further, as shown in FIG. 5, the plurality of rotating shafts 131 include a first rotating shaft 131a, a second rotating shaft 131b, and a third rotating shaft 131c, and the first rotating shaft 131a is sheathed with several first set parts 1311, so The third rotating shaft 131c is provided with a plurality of second sleeves 1312 corresponding to the plurality of first sleeves 131a, and a first fixing plate 1313 is extended on the first sleeve 1311. A second fixing plate 1314 is extended from the two sleeves 1312 , the first fixing plate 1313 is fixedly connected to the first main body 11 , and the second fixing plate 1314 is fixedly connected to the second main body 12 . Specifically, the first setting part 1311 and the second setting part 1312 are guide sleeves, and the first fixing plate 1313 and the second fixing plate 1314 respectively extend from the first setting part 1311 and the second setting part 1311. The square plate on the two sleeves 1312, and the first fixing plate 1313 and the second fixing plate 1314 are fixedly connected to the first main body 11 and the second main body 12 by screws respectively, or, the first fixing The plate 1313 and the second fixing plate 1314 are welded on the first main body 11 and the second main body 12 respectively. The first fixing plate 1313 and the second fixing plate 1314 are fixedly connected to the first main body 11 and the second main body 12 respectively, instead of directly opening through holes on the first main body 11 and the second main body 12 to The way that the rotating shaft passes through for connection facilitates the cleaning of the first body 11 and the second body 12 and prevents dust from accumulating.

In order to further improve, the first rotating shaft 131a is provided with several engaging grooves (not shown in the figure), and the several engaging grooves are spaced apart from the several first sleeves 1311 respectively, that is, they are opposite to each other. One engaging groove is provided between two adjacent first set pieces 1311 .
