[0009] As a further solution of the present invention, the first hinge component and the second hinge component are both of a "X"-shaped structure.

[0010] As a further solution of the present invention, two of the second fixing ribs are located between the plurality of the first fixing ribs.

[0011] As a further solution of the present invention, the plurality of limit strips are all located below the first fixing rib.

[0012] The beneficial effects of the utility model are:

[0013] 1. By arranging the first fixing rib, the second fixing rib and the support plate inside the first hinge component and arranging the second reinforcing rib inside the second hinge component, the first hinge component and the second hinge component can be strengthened, the impact resistance of the first hinge component and the second hinge component can be increased, the hinge can be prevented from deformation, and the service life of the hinge can be improved.

[0014] 2. By setting the elastic steel plate, the elastic steel plate is set inside the first hinge component. The elastic steel plate is in a stressed state, which will generate an outward pushing force on the first hinge component, so that the first hinge component will not be easily deformed when impacted, further improving the service life of the hinge.

[0015] 3. By setting the first reinforcing rib, the first reinforcing rib reinforces the first hinge component outside the first hinge component, further increasing the strength of the first hinge component and once again improving the impact resistance of the hinge.
