[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] See also Figure 1-Figure 5The adjustable hallux valgus device shown in the figure comprises a sole fixing part, a toe fixing part and an adjusting mechanism for adjusting the hallux valgus angle of the toe fixing part. In this embodiment, the toe fixing part comprises an adjusting frame 10 and a toe fixing belt 1, and the toe fixing belt 1 is connected to the end of the adjusting frame 10. The sole fixing part comprises a sole fixing sleeve 4, and a fixing seat 9 with a spherical end surface and a ball and socket structure 101 matched with the spherical surface of the fixing seat 9 are provided between the toe fixing part and the sole fixing part. The ball and socket structure 101 and the fixing seat 9 are movably connected by a pin buckle 11 Then, the fixing seat 9 can be set on the toe fixing part, and can also be set on the sole fixing part. The ball and socket structure 101 and the fixing seat 9 are arranged relative to each other. In this embodiment, the fixing seat 9 is fixedly connected to the sole fixing bag 4 on the sole fixing part. The fixing seat 9 and the sole fixing bag 4 are bonded and fixed by the adhesive pad 8. In this embodiment, the ball and socket structure 101 and the adjustment frame 10 on the toe fixing part are an integrated structure. The fixing seat 9 with a hemispherical end face cooperates with the ball and socket structure 101 to realize multi-directional rotation of the toe fixing parts of both.

[0022] The ball and socket structure 101 described in this embodiment is provided with a through groove 1011 for the pin buckle 11 to pass through and slide. One end of the pin buckle 11 is buckled with the fixing seat 9, and the other end is provided with a cap portion 111 that limits the ball and socket structure 101 from sliding out. In this embodiment, the through groove 1011 is a long groove, and the pin buckle 11 can slide in the long groove, so that the adjustment frame 10 of the toe fixing part can move at the eversion angle, and the adjustment of the angle is achieved through the adjustment mechanism. In this embodiment, the pin buckle 11 passes through the fixing seat, and the pin buckle is inserted into one end of the fixing seat. There are locking protrusions 112 on both sides, and a groove 113 is opened on the pin buckle between the two locking protrusions, and elastic recovery is provided through the groove and the elasticity of the pin buckle itself.

[0023] The adjustment mechanism described in this embodiment includes an adjustment fixing belt 2 that presses the adjustment frame 10 to one side of the sole fixing bag 4 and / or a rear support fixing belt 3 connected between the adjustment frame 10 and the sole fixing bag 4, and the angle adjustment of the adjustment frame 10 is achieved by adjusting the tightness of the adjustment fixing belt 2 and / or the rear support fixing belt 3. In this embodiment, the hallux valgus angle can be adjusted by two or one of the adjustment methods. The tighter the adjustment fixing belt 2 is tied to the sole fixing bag 4, the more the toe end of the adjustment frame 10 will bend inwards. On the contrary, the looser the adjustment fixing belt 2 is, the more the toe end of the adjustment frame 10 will be turned outwards. The hallux valgus angle can be adjusted by controlling the tightness of the adjustment fixing belt 2; the other adjustment method has the same principle but different adjustment components. The other adjustment method is to adjust the tightness of the rear support fixing belt 3. The principle is the same as that of the adjustment fixing belt 2, and it will not be repeated here.

[0024] In order to make the part in contact with the toes to be made of flexible material, in this embodiment, one side of the sole fixing sleeve 4 is extended to the side of the toe fixing belt 1 and connected to the toe fixing belt 1. A set 5 is provided on the toe fixing belt 1, and the set 5 is fixedly connected to the toe fixing belt 1. One end of the set 5 is open, and one end of the adjustment frame 10 is inserted from the opening and sleeved with the set 5. The setting of this structure makes the adjustment frame 10 more convenient and quick when installing. Only the end needs to be inserted into the set 5, and no other fixing method is required. In addition, since the sole fixing sleeve 4 is connected to the toe fixing belt 1, the adjustment frame 10 will not fall off after being inserted into the set 5. In this embodiment, the first connecting buckle 6 and the second connecting buckle 7 are respectively provided on the rear side of the upper and lower sides of the sole fixing sleeve, and a connecting groove 102 for connecting the rear supporting fixing belt is provided on one end of the adjustment frame facing the rear supporting fixing belt, wherein one end of the rear supporting fixing belt is connected to the first connecting buckle at the lower end of the sole fixing sleeve, and the other end of the rear supporting fixing belt is connected to the rear end of the adjustment frame after passing through the second connecting buckle 7.

[0025] In this embodiment, the adjustment fixing belt 2 and the sole fixing bag 4 are bonded by Velcro. In this embodiment, the outer surface of the sole fixing bag 4 is a furry surface, and the inner surfaces of both ends of the adjustment fixing belt 2 are designed as hook surfaces, which are bonded to the furry surface through the hook surfaces.
