[0028] By compressing the distance between the transversely retractable handles 3, the end of the fixed slide groove is used as a fulcrum to drive the top of the movable rod 102 to expand outward, and the angle between the movable rod 102 and the fixed rod outside the wire winding frame is adjusted, so that the movable rod 102 is parallel to the fixed rod 101 of the wire winding frame so that the wire winding frame is rectangular, wherein the wire-binding frame 2 includes a rectangular side bar, a middle transverse transverse connecting rod 203 and a longitudinal longitudinal connecting rod 204, and the side of the rectangular side bar is provided with symmetrical raised forming grooves, and the positions of the raised forming grooves and the grooves 103 correspond. The transverse connecting rod 203 connects the two sides of the rectangular side bar, and the end of the transverse connecting rod 203 is connected to the fixed rod through a rotating shaft, and the longitudinal connecting rod 204 connects the upper and lower parts of the rectangular side bar.

[0029] The ligature wire is wound from the groove 103 of the movable rod 102 outside the wire winding frame on either side, and the winding is stopped when the actual required amount is reached. The wire-binding frame is rotated 120-180° around the transverse connecting rod, and the ligature wire is formed once under the action of the ligature wire forming groove 206. The wire-binding frame is returned along the original path to the same horizontal state as the wire winding frame, and the symmetrical forming of the two ends of the ligature wire is completed.

[0030] Furthermore, as shown in FIG2 , the rectangular side bars of the ligature frame 2 include long side bars 201 that are symmetrical on the left and right and short side bars that are symmetrical in the upper and lower positions. An outwardly protruding ligature wire forming groove 206 is provided in the middle of the long side bar 201. The transverse connecting rod 203 is perpendicular to the fixed rod 101 through a rotating bolt at the end. A rotating handle 205 is provided on the top short side bar 202.

[0031] When in the wire winding working state, the wire winding frame 1 and the wire tying frame 2 are in the same plane, and are approximately in an isosceles trapezoidal shape from bottom to top, so that the ligating wire can be easily removed from the wire winding frame 1 after being formed.

[0032] In the present device, the length of the movable rod 102 is greater than that of the fixed rod 101, and the top angle θ between the movable rod 102 and the fixed rod 101 can be selected to be in the range of 1.0°-10.0°. The angle θ can be controlled by the retractable connector 8 to adjust the winding length of the ligature wire. The size of the ligature wire forming groove 206 is a diameter d of 2-5 mm. The constant horizontal width range of the bottom of the wire winding frame 1 can be selected to be 6-16 cm; or preferably 8-12 cm. The orthodontic ligature wire former is made of stainless steel, polytetrafluoroethylene or any material that can be used for medical devices.

[0034] In the original state of the device, the wire winding frame is in the shape of an isosceles trapezoid as a whole, and the wire winding frame 1 and the wire tying frame 2 are in the same parallel plane. By compressing the transversely retractable handle 3, the angle of the movable rod 102 outside the wire winding frame is adjusted to make it parallel to the fixed rod 101 so that the wire winding frame is in a rectangular shape, and at the same time, the retractable connector 8 is adjusted to make the bottom fixed horizontal width at 10cm. Start winding the ligature wire from the groove 103 of the movable rod 102 outside the wire winding frame on either side, and stop winding when the actual required amount is reached.

[0035] With the help of the force of the wire-binding frame rotating handle 205, the wire-binding frame is rotated 120-180° clockwise in a direction perpendicular to the fixed rod 101, and the ligature wire is formed in one step under the action of the ligature wire forming groove 206, and the wire-binding frame 2 is returned along the original path to the same horizontal state as the wire winding frame 1, completing the symmetrical forming of the two ends of the ligature wire.

[0036] Use scissors to cut and remove the central longitudinal connecting rod 204, or reset the transverse telescopic handle 3 until the wire winding frame 1 is in an isosceles trapezoidal shape and then directly remove it from the top for orthodontic clinical use.
