[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] This embodiment provides a hallux valgus corrector, which includes a toe connection part 1, a corrector fixing part 2, a transition part 3 and an adjustment component 4. Binding straps are additionally provided on the toe connection part 1 and the corrector fixing part 2. These binding straps are prior art and will not be elaborated in detail here. Among them, the toe connection part 1 is movably connected to the transition part 3, and the transition part 3 is movably connected to the corrector fixing part 2. The adjustment component 4 includes a traction member 41 connected to the toe connection part 1 and a rotating member 42 that drives the traction member 41 to move. The rotating member 42 is rotatably connected to the transition part 3. Driving the rotation of the rotating member 42 drives the toe connection part 1 to flip through the traction member 41 to achieve the purpose of adjusting the angle. In this embodiment, the rotating member 42 is manually driven to drive the traction member 41. In this embodiment, the traction member 41 is a rope. When the rotating member 42 rotates, it drives the rope to wind around the rotating member 42, causing the other end of the rope to move towards the side of the rotating member 42, thereby driving the toe connection part 1 to tilt outwards to achieve the purpose of adjusting the angle. In this embodiment, the position of the adjustment can be fixed by a locking and fixing method between the rotating member 42 and the transition part 3. For example, a locking screw is provided between the transition part 3 and the rotating member 42. The locking screw is threadedly connected to the transition part 3. When the rotating member 42 rotates to the required state, tightening the locking screw can keep the rotating member 42 in this state, and thus keep the traction member 41 in a tightened state.

[0026] Embodiment 2

[0027] See Figures 1 - 7, as shown in the figure, the difference between this embodiment and the first embodiment is that: in this embodiment, a ratchet tooth 421 structure is provided on the rotating member 42, and a handle 43 is further included. The handle 43 is movably arranged on the rotating member 42. A space for the traction member to pass through is provided at the middle position of the front end of the handle. A locking device is provided on the handle 43 that is movably engaged in the tooth groove of the ratchet tooth 421 on the rotating member 42. The handle 43 drives the rotating member 42 to rotate in one direction through the locking device. In this embodiment, the locking device includes a locking member 44 and an elastic member 45. Among them, the locking member 44 is slidably fitted on the handle 43. One end of the elastic member 45 abuts against the locking member 44, and the other end abuts against the handle 43. In this embodiment, a cross bar 441 is provided on the locking member 44. The cross bar 441 can be movably engaged in the tooth groove of the ratchet tooth 421. When the handle 43 rotates backward, it can drive the rotating member 42 to rotate to tighten the traction member 41. In this embodiment, two positioning protrusions 431 are provided on the handle 43, so that a sliding groove 432 for the locking member 44 to slide is formed between the two positioning protrusions 431 and the handle 43. The locking member 44 is slidably fitted in the sliding groove 432. In addition, the cross bar 441 penetrates through the handle 43, and a long groove 433 for restricting the movement range of the cross bar 441 is provided on the handle 43. The cross bar 441 is inserted and fixed on the locking member 44, and both ends are respectively inserted into the long groove 433 of the handle. The elastic member 45 is arranged at the tail of the locking member 44, and a limiting mechanism for preventing the elastic member 45 from coming out is provided between the locking member 44 and the handle 43. The specific limiting mechanism is to provide a positioning post 442 at the tail of the locking member 44. The elastic member 45 is sleeved on the positioning post 442, and a positioning groove 434 is provided on the handle 43 at the other end of the elastic member 45. One end of the elastic member 45 is placed in the positioning groove 434. Through the setting of the positioning post 442 and the positioning groove 434, the elastic member 45 will not come out easily.

[0028] In order to prevent the rotating member 42 from rotating when the handle 43 is pushed forward, this embodiment further provides an unlocking member 46 for preventing the rotating member 42 from reversing. The unlocking member 46 is slidably connected to the transition member 3, and a clamping portion 461 extending toward the tooth groove side of the ratchet tooth 421 structure of the rotating member 42 is provided on the unlocking member 46. By driving the unlocking member 46 to slide, the clamping portion 461 is disengaged from the tooth groove of the ratchet tooth 421, and the reverse rotation restriction of the rotating member 42 is released. At least one end of the unlocking member 46 extends to the outside of the transition member 3. A spring 47 is provided between the unlocking member 46 and the transition member 3. The spring 47 makes the unlocking member 46 normally stuck in the tooth groove of the ratchet tooth 421. Due to the special properties of the two side surfaces of the teeth of the ratchet tooth 421, the ratchet tooth 421 is restricted by the unlocking member 46 during reverse rotation, while when the ratchet tooth 421 rotates forward, it can rotate normally as long as it can overcome the elastic force of the spring 47. When the unlocking member 46 is pushed backward to the unlocking state, the ratchet tooth 421 is not affected by forward or reverse rotation.

[0029] In this embodiment, the transition member 3 is composed of a first part 31 and a second part 32 spliced together. The first part 31 and the second part 32 are fixed by screws. An integrally formed plug 21 for engaging with the transition member 3 is provided on the orthosis fixing part 2. A clamping part for actively clamping the plug 21 is formed between the first part 31 and the second part 32. In this embodiment, the cross-section of the plug 21 is T-shaped or mushroom-shaped. Semi-circular notches 33 are provided on both the first part 31 and the second part 32. After the first part 31 and the second part 32 are spliced, a circular hole is formed, which limits the sliding out of the clamping part 461 and enables relative rotation between the transition member 3 and the orthosis fixing part 2.

[0030] In this embodiment, the connection between the toe connecting part 1 and the transition member 3 is achieved by providing a sphere 11 at one end of the toe connecting part 1 where it is connected to the transition member 3. The first part 31 and the second part 32 are provided with clamping parts 34 for actively clamping the sphere 11. The clamping part can be an inwardly concave spherical socket structure matching the sphere, or a hole groove into which the sphere can be inserted. The sphere 11 is clamped by the two clamping parts 34 to prevent it from sliding out. In this embodiment, a connecting rod 12 is provided between the toe connecting part 1 and the sphere 11. A gap for the directional movement of the connecting rod 12 is formed between the two clamping parts 34. Therefore, the toe connecting part 1 can rotate relative to the transition member 3.

[0031] In this embodiment, a fixed shaft 35 is integrally formed or connected to the first part 31 or the second part 32. The rotating member 42 is sleeved on the fixed shaft 35. The rotating member 42 includes a first ratchet wheel 422 and a second ratchet wheel 423. The first ratchet wheel and the second ratchet wheel are in transmission cooperation through a transmission part 424 and are fixed into an integral structure by screws. The transmission part 424 is provided separately or is an integral structure with one of the ratchet wheels. The traction member 41 is connected to the transmission part 424. The handle 43 is sleeved on the transmission part 424. In this embodiment, an installation groove 425 with an arc-shaped cross-section and an opening on one side is provided on the transmission part 424. The traction member 41 is stuck in the installation groove. Since the traction member 41 is a rope and is a woven belt-type rope in this embodiment, the friction between the traction member 41 and the installation groove is relatively large. Therefore, when the rotating member 42 rotates, it will drive the traction member 41 to tighten. In this embodiment, a connecting convex rod 13 for connecting the traction member 41 is provided on the toe connecting part 1. The traction member 41 is connected to the connecting convex rod 13. The traction member 41 can be a rope with both ends respectively fixed to the toe connecting part 1 and the rotating member 42, or a closed-loop rope with both ends respectively sleeved on the toe connecting part 1 and the rotating member 42.
