When the male hinge 200 is unfolded to 180 degrees, the limiting block 214 is separated from the slideway 103, the limiting block 214 extends out of the chute 212 under the action of the second elastic piece 213, the limiting block 214 is clamped with the inclined surface of the second slideway body 1032 to prevent the male hinge 200 from moving along the folding direction, meanwhile, the bottom of the adjusting piece 104 contacts with the second hinge body 201 to limit the male hinge 200 to continue to move along the unfolding direction, the unfolding hinge 1000 is locked, at the moment, the micro switch stop rod 205 contacts with the micro switch 105, the micro switch 105 is triggered, and the unfolding hinge 1000 is unfolded to generate a signal.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
