[0014] The beneficial effect of the further scheme is that it is convenient to reserve the activity space for the deformation of the U-shaped shaft.

[0015] Compared with the prior art, the technical scheme has the following beneficial effects:

[0016] The double-shaft embracing gear elastic positioning hinge realizes the mortise fixing between the plug-in toothed plate and the toothed plate through the U-shaped shaft and the inner tooth hole engagement, reduces the dependence of the hinge on the size of the fixing screw or mortise nail tension, enhances the service life of the hinge, and solves the problem that the existing hinges are connected in the screw or mortise connection mode, so that the hinge connection part is loose after being used too many times, resulting in poor stability.

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] Embodiment one, please refer to Figures 1 to 4This embodiment of a dual-axis encircling gear elastic positioning hinge includes a temple 1 and a frame 2. A dual-axis encircling gear hinge mechanism is provided between the temple 1 and the frame 2. The dual-axis encircling gear hinge mechanism is fixedly installed on a connecting block 3 on the surface of the frame 2. Two toothed plates 4 are fixedly installed on the surface of the connecting block 3. The toothed plates 4 have round holes 5 and two shaft holes 6. A U-shaped shaft 7 is inserted into the shaft hole 6. The diameter of the U-shaped shaft 7 is adapted to the diameter of the shaft hole 6 to facilitate the insertion of the U-shaped shaft 7 into the shaft hole 6. A connecting toothed plate 8 is fixedly installed at one end of the temple 1. The thickness of the connecting toothed plate 8 is adapted to the distance between the opposite surfaces of the two toothed plates 4 to facilitate the insertion of the connecting toothed plate 8 between the two toothed plates 4. An internal toothed hole 9 is provided on the surface of the connecting toothed plate 8. The round holes 5 and the shaft holes 6 correspond to the internal toothed hole 9 to facilitate the U-shaped shaft 7 passing through the internal toothed hole 9.

[0025] Shaft holes 6 are symmetrically distributed on both sides of the circular hole 5. A connecting groove 10 is provided between the shaft holes 6 and the circular hole 5 to facilitate the provision of movement space for the deformation of the U-shaped shaft 7.

[0026] It should be noted that both the toothed plate 4 and the insertion toothed plate 8 in this embodiment are made of elastic material.

[0027] Example 2, please refer to Figure 5 The two teeth plates 4 can be magnetically connected to the middle of the glasses. The insert teeth plate 8 is connected to the middle of the new glasses hanger. The new glasses hanger can be connected to the glasses frame using the teeth plates 4 and the insert teeth plate 8.

[0028] The working principle of the above embodiments is as follows:

[0029] In use, insert the connecting tooth plate 8 between the two tooth plates 4, so that the round hole 5 and the shaft hole 6 correspond to the internal tooth hole 9. Insert the U-shaped shaft 7 into the shaft hole 6, and at the same time, make the U-shaped shaft 7 pass through the internal tooth hole 9, so that the U-shaped shaft 7 engages with the tooth groove on the inner side of the internal tooth hole 9. When the temple 1 is rotated, the connecting tooth plate 8 rotates synchronously with the temple 1, so that the connecting tooth plate 8 rotates on the U-shaped shaft 7, so that the protrusion on the inner side of the internal tooth hole 9 squeezes the U-shaped shaft 7, causing the U-shaped shaft 7 to deform, so that the U-shaped shaft 7 can be engaged in the other tooth groove.
