[0041] The hinge mounting kit further comprises the limiting structure.
[0042] One end of the first sub-hinge arm 400 is hingedly connected to the first hinge arm 200, one end of the second sub-hinge arm 500 is hingedly connected to the second hinge arm 300, the other end of the first sub-hinge arm 400 is hingedly connected to the other end of the second sub-hinge arm 500.
[0043] One end of the first support arm 600 is hingedly connected to the first hinge arm 200, one end of the second support arm 700 is hingedly connected to the second hinge arm 300, the other end of the second support arm 700 is hingedly connected to the first support arm 600, and the other end of the first support arm 600 is hingedly connected to the second sub-hinge arm 500.
[0044] The other end of the first support arm 600 is provided with a connecting shaft 610, and the damper 800 is arranged between the first connecting shaft 410, at which the first sub-hinge arm 400 and the second sub-hinge arm 500 are hingedly connected, and the connecting shaft 610.
[0045] The support block 100 is inserted into the second connecting shaft 510, at which the second sub-hinge arm 500 and the second hinge arm 300 are hingedly connected, through the opening 110.
[0046] In the embodiment, the hinge connection point of the first support arm 600 and the first hinge arm 200 is close to the side of the hinge connection point of the first hinge arm 200 and the first sub-hinge arm 400, which is close to the second hinge arm 300.
