[0023] 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.

[0024] Example

[0025] See also Figure 1-Figure 9 , as shown in the figure, is a knob-adjustable hallux valgus corrector, comprising a sole fixing part fixed at the sole position, a toe fixing part fixed on the toes, and an adjusting mechanism for adjusting the angle of the toe fixing part, wherein the sole fixing part comprises a sole fixing frame 4, a sole fixing strap 2 and a rear-drag fixing strap 3; the toe fixing part comprises a big toe connecting frame 5 and a big toe fixing strap 1, and also comprises an axis core 7, the axis core 7 is rotatably connected to the sole fixing part, that is, connected to the sole fixing frame 4, the upper end of the axis core 7 is rotatably connected to the toe fixing part through a pin shaft 9, that is, connected to the big toe connecting frame 5, the adjusting mechanism comprises an adjusting wheel 6, the adjusting wheel 6 is movably arranged on the sole fixing part, the side of the adjusting wheel 6 contacting the toe fixing part is provided with protrusions 61 of different height differences, the corresponding toe fixing part is provided with a positioning groove 51 for the end of the protrusion 61 to be clamped, and the toe fixing part is pressed by the protrusions 61 of different heights to adjust the valgus angle of the toe fixing part. In this embodiment, the protrusions 61 are arranged at a certain distance, and the protrusions are arranged in a ring array at the outer end of the adjusting wheel.

[0026] In this embodiment, the adjusting wheel 6 is rotatably sleeved on the shaft core 7, and the shaft core 7 is rotatably connected to the sole fixing part through the fastener 10, that is, the shaft core is connected to the sole fixing frame 4 through the fastener 10. In this embodiment, a mounting hole is provided on the sole fixing frame, and the fastener is a bolt or a rivet. The fastener 10 is not locked after connecting the shaft core 7 to the sole fixing frame 4, and only limits the axial displacement of the shaft core 7 so that the shaft core can rotate freely. In this way, when the corrector is worn, the big toe of the foot can move up and down, and the big toe moving up and down will drive the big toe connecting frame 5 and the shaft core 7 to rotate relative to the sole fixing frame 4, making the corrector more comfortable to wear.

[0027] In this embodiment, the lower end of the adjusting wheel 6 abuts against the sole fixing part, and a limiting mechanism for limiting the axial displacement of the adjusting wheel 6 is provided between the adjusting wheel 6 and the shaft core 7.
