Direction R2 rotates.

Both the first rotating shaft 110 and the second rotating shaft 120 cannot rotate in the second hour hand direction R2, so that if the hinge 100 continues to switch to a larger angle state, it can only rotate through the second rotating shaft 120 in the first hour hand direction R1, which is equivalent. The first rotating shaft 110 and the connecting bracket 130 can only rotate in the second hour hand direction R2 with the second rotating shaft 120 as a center; however, when the hinge 100 is at 90 degrees, the second rotating shaft 120 cannot continue to rotate in the first hour hand direction R1. The second rotating shaft 120 needs to be unlocked so as to be rotatable in the first hour hand direction R1. When the hinge 100 is at 270 degrees, the first end 151 and the second end 152 of the second latch 150 respectively correspond to the recess 222 of the second cam 220 and the recess 242 of the fourth cam 240, so that the second shaft 120 can be along the second The first direction pin R1 rotates, and during the rotation of the second shaft 120 in the first hour hand direction R1, the second pin 150 is gradually pushed toward the other end. That is, during the rotation of the second rotating shaft 120 in the first hour hand direction R1, the convex portion 241 of the fourth cam 240 of the second rotating shaft 120 pushes the second end 152 of the second latch 150 to gradually slide the second latch 150. To the other end, and snapped into the recess 222 of the second cam 220 of the first reel 110, and finally the first end 151 of the second latch 150 will abut the first end 223 of the recess 222 of the second cam 220.

Please refer to FIG. 5 and FIG. 9A to FIG. 9C simultaneously. FIG. 9A is a schematic diagram of the hinge 100 of FIG. 2 at 360 degrees and some components are omitted, and FIG. 9B is the hinge 100 of FIG. 9A for the first latch 140, AA cross-sectional view of a cam 210 and a third cam 230, and FIG. 9C is a BB cross-sectional view of the hinge 100 of FIG. 9A for the second pin 150, the second cam 220, and the fourth cam 240.

When the hinge 100 is at 270 degrees, the first rotating shaft 110 can be rotated in the first hour hand direction R1 to switch to a state of a smaller angle (that is, when the hinge 100 is at 270 degrees, it can be turned back to 90 degrees or other smaller. Angle). However, when the hinge 100 is at 360 degrees, the first rotating shaft 110 cannot rotate in the first hour hand direction R1 and cannot rotate in the second hour hand direction R2. Therefore, if the hinge 100 is in 360 degrees, it is only required to switch to a smaller angle state. The first rotating shaft 110 and the connecting bracket 130 can be rotated integrally in the first hour hand direction R1, that is, from the position of FIG. 9C to the position of FIG. 8C.
