Due to the relative rotation between the first hinge member 1 and the second hinge member 2, the positioning pin 41 is inserted into the new positioning hole 8, and the first hinge arm 12 and the second hinge arm 22 are limited again, completing the angle fixing between the first hinge arm 12 and the second hinge arm 22, and achieving the angle fixing between the external objects.

[0064] The technical solutions provided by the embodiments of the present invention are introduced in detail above.
