And the shape and curvature of the first chute 122 and the second chute 25 of this embodiment can be adjusted according to the thickness of the first object 8 and the second object 9, so that the center of curvature passing through the first chute 122 And the center axis of rotation A of the center of curvature of the second chute 25 is higher than the top surfaces of the first object 8 and the second object 9, that is, when the first object 8 and the first object 8 pivot toward each other, they will not stuck against each other.

To sum up, the thin hinge 10 of the present invention passes through the first chute 122 for the first protruding rail 23 of the connecting member 2 to enter through the first chute entrance 122a of the base member 1, and for the The second protruding rail 33 of the slider 3 enters the second chute 25 through the second chute inlet 251 of the connector 2, so that the connector 2 and the slider 3 do not need to be disassembled into multiple parts for manufacture, and Cooperating with the frame member 4 , the sliding center column 5 and the torsion bar 6 with a less complex structure and a smaller space occupation, the thin hinge 10 can be easily positioned in a specific rotation angle range without being easily rotated , thereby saving the manufacturing cost, simplifying the assembly process, and making the hinge thinner. Therefore really can reach the purpose of this utility model.

However, the above-mentioned ones are only embodiments of the present utility model, and should not limit the scope of implementation of the present utility model with this. It belongs to the scope covered by the utility model.
