[0013] When the folding hinge is turned from the folding state to the first gear state, the toggle lever is rotated upward, and the elastic clamping structure is inserted into the first clamping groove;

[0014] When the folding hinge is changed from the first gear state to the folding state, the toggle lever is first rotated upward, the elastic clamping structure is fixed to the yielding portion, and the elastic clamping structure is disengaged from the toggle lever; then the toggle lever is rotated downward, and the reset ring does not rotate until the elastic clamping structure passes over the first clamping groove, and the toggle lever is continued to be rotated, and the toggle lever drives the reset ring to rotate synchronously, and the elastic clamping structure abuts against the toggle lever; the toggle lever is continued to be rotated downward to realize the folding of the folding hinge.

[0015] By adopting the above technical solution, when the folding hinge is turned from the folded state to the first gear state, the elastic snap-fit ​​structure is inserted into the first snap-fit ​​groove, and the structure is stable and stable; when the folding hinge is turned from the first gear state to the folded state, it is only necessary to turn the toggle lever upward and then turn the toggle lever downward, which is quick, smooth and easy to use.

[0017] By adopting the above technical solution, the distance between the yielding portion and the toggle rod is greater than the distance between other positions on the reset ring and the toggle rod. When the elastic clamping structure is fixed to the yielding portion, the elastic clamping structure is forced to lift toward the end away from the toggle rod, thereby achieving disengagement of the elastic clamping structure from the toggle rod.

[0018] Optionally, an annular protrusion is provided at one end of the reset ring close to the shell, and the elastic snap-fit ​​structure abuts against the end face of the annular protrusion; the yielding portion is provided at one end of the annular protrusion close to the shell, and the yielding portion includes a limiting groove, and the distance between the bottom of the limiting groove and the toggle rod is greater than the distance between the end face of the annular protrusion and the toggle rod; the elastic snap-fit ​​structure can slide into and be fixed in the limiting groove; a second guide slope is provided between the end face of the annular protrusion and the notch of the limiting groove.

[0019] By adopting the above technical solution, when the reset ring is rotated, the limit column can slide on the annular protrusion; when the elastic clamping structure needs to be disengaged from the toggle rod, the reset ring is rotated to make the limit column slide into the limit groove along the second guide slope, and the distance between the bottom of the limit groove and the toggle rod is greater than the distance between the end face of the annular protrusion and the rotating ring, so that the elastic clamping structure is lifted; at the same time, the limit groove has a certain limiting effect on the elastic clamping structure, and can fix the elastic clamping structure in the limit groove; when the rotating ring rotates in the opposite direction, the elastic clamping structure can slide out of the limit groove and return to the end face of the annular protrusion along the second guide slope.

[0020] Optionally, the elastic clamping structure includes an elastic clamping block and a limiting column, the elastic clamping block has an elastic force toward the direction of the toggle rod, and the elastic clamping block can be inserted into the first clamping groove; the limiting column is fixedly connected to one end of the elastic clamping block close to the rotating shaft, and the limiting column abuts against the end face of the annular protrusion or slides into and is fixed in the limiting groove.

By rotating the toggle rod, the elastic card block can be inserted into the first card slot, or the limit column can be slid into and fixed in the limit slot. The structure is simple and the operation is easy, which ensures the stability of the folding hinge and improves the reliability of the folding hinge.

[0022] Optionally, the elastic block includes a clamping block and an elastic member, the elastic member is installed between the clamping block and the shell, and the elastic member provides a thrust toward the toggle rod to the clamping block; the limiting column is fixedly connected to one end of the elastic block close to the rotating shaft.

[0024] Optionally, a first guiding slope is provided at one end of the clamping block close to the reset ring, and the first guiding slope is tightened in a direction away from the reset ring toward the fixed ring and toward the axis of the clamping block.

[0025] By adopting the above technical solution, when a force is applied to the clamping block, the clamping block can slide out of the first clamping groove along the first guide slope; at the same time, the setting of the first guide slope makes the clamping block more stable when sliding out of the first clamping groove, avoiding violent collisions, helping to extend the service life of the clamping block and the reset ring, and improving the reliability of the entire folding hinge structure.

[0026] Optionally, a reset hole is provided on the toggle rod, and a reset block is provided on one end of the reset ring facing the toggle rod.

[0027] By adopting the above technical solution, when the reset block slides in the reset hole, the toggle rod rotates and the reset ring does not move; when the limit column is fixed in the limit groove, the clamping block disengages from the toggle rod, and the toggle rod is rotated until the elastic clamping structure passes the first clamping groove and abuts against the toggle rod. At this time, the reset block abuts against the upper groove wall of the reset hole, and the toggle rod continues to be rotated. The toggle rod drives the reset ring to rotate synchronously, thereby realizing the folding of the folding hinge.

[0028] Optionally, a second snap-fitting groove is provided on the toggle lever; when the folding hinge is in the first gear state, the toggle lever is continued to be rotated upward to the second gear state, the elastic snap-fitting structure is inserted into the second snap-fitting groove, and the toggle lever is fixed obliquely upward.
