Further, when the tightness of the traction wire 30 needs to be adjusted after operation, a minimally invasive incision is formed on the skin of the chin portion 92 of the patient, the second matching portion 411 of the screwdriver 41 penetrates the skin of the chin portion 92 through the minimally invasive incision and is connected with the first matching portion 2212 of the winding shaft 22, and the tightness of the traction wire 30 can be adjusted by rotating the screwdriver 41 to drive the winding shaft 22 to rotate forward or reverse. The whole adjusting operation is simple, the trauma to the patient is small, and meanwhile, the mucous membrane injury and infection can be avoided due to the fact that the minimally invasive incision is small and is positioned on the outer skin of the mouth.
Optionally, in an embodiment, one of the first engaging portion 2212 and the second engaging portion 411 is provided with an engaging groove 2213 for inserting the other, a groove wall of the engaging groove 2213 is provided with an internal thread, and the other is provided with an external thread matching the internal thread. For example, in the present embodiment, the first engaging portion 2212 is provided with an engaging groove 2213 for inserting the second engaging portion 411, and a groove wall of the engaging groove 2213 is provided with an internal thread. Referring to fig. 5, the second fitting part 411 is provided with external threads that match the internal threads. Thus, the second fitting portion 411 is inserted into the fitting groove 2213, and the screw driver 41 and the winding shaft 22 can be connected by the external thread and the internal thread, so that the winding shaft 22 can be driven to rotate synchronously by rotating the screw driver 41.

Further, the screwdriver piece 41 can drive the winding shaft 22 to move along the axial direction, so that the first anti-reverse tooth 2214 is clamped or separated from the second anti-reverse tooth 212, and the winding shaft 22 is further converted between a unidirectional rotation state and a bidirectional rotation state.
Specifically, when the traction wire 30 needs to be tightened, the screwdriver piece 41 compresses the winding shaft 22, so that the first anti-reverse tooth 2214 of the winding shaft 22 is clamped with the second anti-reverse tooth 212 in the accommodating groove 211, at this time, the winding shaft 22 is driven to rotate forward by the screwdriver piece 41 to tighten the traction wire 30, at this time, the reverse rotation of the winding shaft 22 is limited, and after the screwdriver piece 41 is separated from the winding shaft 22 after the adjustment is completed, the winding shaft 22 cannot be reversed, so that the tightened traction wire 30 is prevented from loosening again due to the reverse rotation of the winding shaft 22. When the traction wire 30 needs to be loosened, the rolling shaft 22 is pulled out through the screwdriver piece 41, so that the first anti-reversion teeth 2214 of the rolling shaft 22 are separated from the second anti-reversion teeth 212 in the accommodating groove 211, at the moment, the rolling shaft 22 can freely rotate bidirectionally, the rolling shaft 22 is driven to rotate reversely through the screwdriver piece 41, the traction wire 30 can be loosened, after the traction wire 30 is adjusted to a proper tightness, the rolling shaft 22 is tightly pressed through the screwdriver piece 41, and the first anti-reversion teeth 2214 of the rolling shaft 22 are clamped with the second anti-reversion teeth 212 in the accommodating groove 211, so that the rolling shaft 22 can be limited to rotate, and the tightness of the traction wire 30 at the moment can be fixed.
