[0026] Example 1:
[0027] Please see the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides an auxiliary device that can reduce orthodontic force and adjust the direction of force application, including a ball 1, a limiting groove 2 is provided on the top of the ball 1, the ball 1 can provide an installation position, and can also serve as a fixed pulley to change the direction of force, the outer wall of the ball 1 is located at the bottom end of the limiting groove 2 and is provided with a plurality of wire entry holes 3, the limiting groove 2 can limit the moving position of the wire entry holes 3, and prevent the wire entry holes 3 from sliding from the outside of the ball 1, and the limiting groove 2 is a straight groove, and the number of the wire entry holes 3 is two, and they are respectively provided in the limiting groove 2. At both ends, both sides of the interior of the ball 1 are provided with limited sliding grooves 4, and two movable pulleys 5 are arranged between the interiors of the two limited sliding grooves 4. The limited sliding grooves 4 can play an installation role, and can install the movable pulley 5 inside the limited sliding grooves 4, and can make the movable pulley 5 slide inside the limited sliding grooves 4, and can make the movable pulley 5 rotate inside the limited sliding grooves 4, and then can make the movable pulley 5 act as a movable pulley, and the bottom end of the outer wall of the ball 1 is provided with a plurality of wire outlet holes 7, and the wire outlet holes 7 can pass the steel wire out of the interior of the ball 1. A steel wire 6 is sleeved between the two movable pulleys 5. The steel wire 6 is sleeved between the two movable pulleys 5. When the steel wire 6 is pulled, the effect of the two movable pulleys 5 can be utilized to save force. Both ends of the steel wire 6 are detachably connected to a tension spring 10. The bottom of the tension spring 10 is detachably connected to a small hook 8. The bottom of the ball 1 is fixedly connected to a supporting mechanism 9. The steel wire is passed through one of the wire inlet holes 3 at the top of the ball 1, and the steel wire is wound around the groove of the movable pulley 5 on the lower side, and around the groove of the movable pulley 5 on the upper side, and then the wire is taken out from one of them. The hole 7 is passed through, and one end of the steel wire 6 is pressed against the inner wall of the limiting groove 2. The direction of the steel wire 6 is changed by using the inner wall of the limiting groove 2, so the direction of the force can be adjusted, and the cooperation of the two movable pulleys 5 is used. Therefore, the composition of the ball 1 and the limiting groove 2 thereon is equivalent to a fixed pulley, and the cooperation between the two movable pulleys 5 to move the teeth only requires one-third of the original force, thereby reducing the orthodontic force. The orthodontic correction auxiliary device requires the traction buckle to be placed on the lip surface to have a rotational force, so that it can drive the tooth crown to rotate downward.
[0028] The supporting mechanism 9 includes a connecting column 901, which can provide a connection function. The top of the connecting column 901 is fixedly connected to the bottom of the ball 1. A through groove 902 is provided inside the bottom end of the connecting column 901. The through groove 902 can provide a position for the steel wire to pass through. The bottom of the connecting column 901 is fixedly connected to the base 903. The bottom of the base 903 is provided with a buffer pad. The buffer pad can protect the teeth when touching the teeth. One end of the steel wire 6 passes through the inside of the through groove 902.
[0029] One end of the steel wire 6 passes through the inside of one of the wire inlet holes 3, and the other end of the steel wire 6 passes through the inside of one of the wire outlet holes 7. A groove is provided in the middle of the movable pulley 5, which can limit the external placement of the steel wire 6 to prevent the steel wire 6 from deflecting. The steel wire 6 is arranged inside the groove, and a section of the steel wire 6 is arranged inside the limiting groove 2. The diameter of the movable pulley 5 is equal to the width of the limiting slide 4. The diameter of the movable pulley 5 is equal to the width of the limiting slide 4, which can prevent the movable pulley 5 from shaking or tilting when moving or rotating. The interior of the ball 1 is hollow, and the hollow setting can provide an installation position and space for winding ropes. A section of the steel wire 6 is close to the inner wall of the limiting groove 2, and multiple wire outlet holes 7 are The traction buckle is evenly distributed at the bottom of the sphere 1, and the multiple wire entry holes 3 are evenly distributed at the top of the sphere 1. When performing inverted supernumerary tooth traction, the traction buckle needs to be glued to the palatal side of the crown. When performing such an operation, the traction buckle is glued to the lingual side in the first operation, and the tooth is pulled away from the piriform bone of the nasal base, and then a small amount of bone is removed and glued to the labial tooth surface in a second operation, or more bone is removed in the second operation and glued to the labial tooth surface. The length of the radius of the sphere 1 in the present invention can have different rotational forces. The traction buckle is glued to the lingual side during the operation, and the rotational force is generated by the radius of the fixed pulley. Therefore, two operations are not required, and more bone removal is avoided. At the same time, the tooth can be moved with only one-third of the original force, and the device can be subjected to less reaction force.

The cross-shaped limiting groove 2 can increase the direction of force change.
[0032] Working principle: The steel wire is passed through one of the wire inlet holes 3 on the top of the ball 1, and the steel wire is wrapped around the groove of the movable pulley 5 on the lower side, and around the groove of the movable pulley 5 on the upper side, and then passed through one of the wire outlet holes 7, and one end of the steel wire 6 is close to the inner wall of the limiting groove 2. The direction of the steel wire 6 is changed by using the inner wall of the limiting groove 2, so that the direction of the force can be adjusted, and by using the cooperation of the two movable pulleys 5, the movable pulley can play a labor-saving role, thereby reducing the orthodontic force.
