[0026] Compared with the prior art, the toe orthosis provided by the utility model is fixed to the insole 10 by clamping the inter-toe limiter 21 of the limit component 1 20 and the lower fixing plate 1 22 or by screw connection and clamping. The inter-toe limiter 21 presses against the inner side of the big toe, forcing the big toe to deflect outward, and is fixed to the insole 10 by clamping the foot side limiter 31 of the limit component 2 and the lower fixing plate 2 32 or by screw connection and clamping. The foot side limiter 31 is close to an edge of the insole 10 and can be attached to the outer side of the first metatarsal joint of the big toe, thereby limiting the shape of the big toe. In this way, it can not only be worn in shoes for use, but also the hallux valgus can be corrected for a long time and the correction progress can be accelerated. At the same time, the limit component 1 20 and the limit component 2 are more firmly fixed to the insole 10, providing sufficient correction strength and improving the correction effect.

[0027] In one embodiment, see Figure 3The toe-toe limiting member 21 includes a fixing plate 211, a stopper 212 disposed on the top surface of the fixing plate 211, and a clamping pin 212 disposed on the bottom surface of the fixing plate 211. A clamping hole 221 is provided on the lower fixing plate 22. The clamping pin 212 sequentially penetrates the positioning hole 11 and the clamping hole 221 to be clamped with the lower fixing plate 22.

[0028] Specifically, the insole 10 is provided with two positioning holes 11 distributed along the insole 10 in the horizontal direction, and correspondingly, the lower fixing plate 22 is provided with two clamping holes 221. The lower fixing plate 22 is made of plastic material and is made into a flat strip shape, which can improve the wearing comfort, and at the same time can increase the force bearing area and improve the stability of the fixed state of the limiting component 20; the fixing plate 211 is made of plastic and is made into a flat strip shape (similar to the structure of the lower fixing plate 211), and two clamping pins 1 are fixed to the bottom surface of the fixing plate 211. The fixing plate 211, the stopper 212 and the clamping pin 1 are formed by an integrated casting mold, and the clamping pin 1 and the clamping hole 221 are clamped to fix the toe limiter 21 and the lower fixing plate 22 to the upper and lower surfaces of the insole 10 respectively. Of course, the number of the positioning holes 11 can also be 3, 4 or more, and correspondingly, the number of the clamping holes 221 and the clamping pin 1 is the same as the number of the positioning holes 11.

[0029] In another embodiment, two countersunk holes are formed on the fixing plate 1 211, and two screw holes are formed on the lower fixing plate 1 22, and two flat head screws are used to fix the toe stopper 21 and the lower fixing plate 1 22 to the upper and lower surfaces of the insole 10. Of course, the number of the countersunk holes can also be 3, 4 or more, and accordingly, the number of the screw holes and the screws is the same as the number of the countersunk holes.

[0030] In other embodiments, there may be only one clamping hole 221 and one clamping needle. The advantage is that the toe limiter 21 can be fixed on the insole 10 to prevent it from coming off and can also rotate. When the toe limiter 21 rotates, the angle of the side of the block 212 that contacts the toes will also be adjusted. The block 212 can be adjusted according to the shape of the toes, so that the side that contacts the toes can fit better and improve comfort.

[0031] In one embodiment, the card pin 1 includes a rod 213 and a head 214 which are arranged in sequence. The card pin 1 is provided with a through groove 215 which passes through the head 214 up and down and extends toward the rod 213. The head 214 is squeezed by the lateral force and elastically contracts inward through the positioning hole 11 and the card hole 221.

[0032] Specifically, the head 214 protrudes the rod 213 to both sides. During assembly, the head 214 is aligned with the positioning hole 11 and pressed hard. The head 214 is squeezed on the edge of the positioning hole 11, and the through groove 215 is compressed, so that the two sides of the head 214 are brought together and pass through the positioning hole 11 smoothly. The same method is used to press the head 214 into the clamping hole 221.

[0033] In one embodiment, the shape of the rod 213 is cylindrical, the cross-sectional shape of the head 214 is a sector or triangle symmetrically arranged on both sides of the through slot 215, and the clamping hole 221 is a countersunk hole, so that the head 214 can be clamped in the clamping hole 221 after the head 214 is restored to its original state without protruding, thereby improving the wearing comfort.

[0034] In one embodiment, a gasket 216 is provided on one side of the stopper 212 that contacts the toes. The number of the gasket 216 is one or more to adjust the correction strength of the toes. The gasket 216 can be made of EVA foam material with one-sided adhesive and adhered to the stopper 212.

[0035] In one embodiment, see Figure 4 The foot-side limiting member 31 includes a second fixing plate 311, a second stopper 312 arranged on the top surface of the second fixing plate 311, and a second clamping pin arranged on the bottom surface of the second fixing plate 311. A second clamping hole 321 is opened on the second lower fixing plate 32. The second clamping pin passes through the second positioning hole 12 and the second clamping hole 321 in sequence and is clamped with the second lower fixing plate 32.

[0036] Specifically, the insole 10 is provided with two positioning holes 12 distributed laterally along the insole 10, and correspondingly, the lower fixing plate 32 is provided with two clamping holes 321. The lower fixing plate 32 is made of plastic material and is in a flat strip shape, which can improve the wearing comfort, and at the same time can increase the force-bearing area and improve the stability of the fixed state of the limiting component 2; the fixing plate 311 is made of plastic and is in a flat strip shape (similar in structure to the lower fixing plate 311), and two clamping pins 2 are fixed to the bottom surface of the fixing plate 311. The fixing plate 311, the stopper 312 and the clamping pin 2 are formed by an integrated casting mold, and the foot-side limiting component 31 and the lower fixing plate 32 are respectively fixed to the upper and lower surfaces of the insole 10 by clamping the clamping pin 2 with the clamping hole 321. Of course, the number of the positioning holes 12 can also be 3, 4 or more, and accordingly, the number of the clamping holes 321 and the clamping pin 2 is the same as the number of the positioning holes 12.

[0037] In other embodiments, there may be only one card hole 321 and one card pin 32. The advantage is that the foot side limiter 31 can be fixed on the insole 10 to prevent it from coming off and can also rotate. When the foot side limiter 31 rotates, the side of the block 312 that contacts the foot side will also adjust its angle. The block 312 can be adjusted according to the shape of the foot side, so that the side that contacts the foot side can fit better and improve comfort.

[0038] In one embodiment, the second card pin includes a second rod portion 313 and a second head portion 314 which are arranged in sequence. The second card pin is provided with a second through groove 315 which passes through the second head portion 314 up and down and extends toward the second rod portion 313. The second head portion 314 is squeezed inward by the lateral force and elastically contracts through the second positioning hole 12 and the second card hole 321.

[0039] Specifically, the second head portion 314 protrudes the second rod portion 313 to both sides. During assembly, the second head portion 314 is aligned with the second positioning hole 12 and pressed hard. The second head portion 314 is squeezed at the edge of the second positioning hole 12, and the second through groove 315 is compressed, so that the two sides of the second head portion 314 are brought together and pass through the second positioning hole 12 smoothly. The same method is used to press the second head portion 314 into the second clamping hole 321.

[0040] In one embodiment, the shape of the second rod portion 313 is cylindrical, and the cross-sectional shape of the second head portion 314 is a sector or triangle symmetrically arranged on both sides of the second through slot 315, and the second clamping hole 321 is a countersunk hole, so that the second head portion 314 can be clamped in the second clamping hole 321 after the restored state without protruding, thereby improving the wearing comfort.

[0041] In one embodiment, the two sides of the stopper 212 that contact the toes are curved surfaces, and the one side of the stopper 2 312 that contacts the toes is a curved surface, which can improve wearing comfort and facilitate long-term wearing correction.

[0042] In one embodiment, the lower fixing plate 1 22 and the lower fixing plate 2 32 can be designed as an integral unit with the insole 10 .

[0043] In one embodiment, the insole 10 is provided with a groove 13 and a groove 2 14, and the toe stopper 21 and the foot side stopper 31 are respectively embedded in the groove 13 and the groove 2 14. The height of the fixing plate 1 211 and the fixing plate 2 311 protruding from the insole 10 can be reduced or not protruded to avoid hurting the foot.
