[0025] Consisting of Figures 1 to 4As shown in the figure, the utility model includes a first pliers arm 1 and a second pliers arm 2 which are hinged. A first pliers head 11 is provided at the front end of the first pliers arm 1, and a second pliers head 21 is provided at the front end of the second pliers arm 2. A first bent seat 31 is inserted on one side between the first pliers head 11 and the second pliers head 21, and a second bent seat 32 is inserted on the other side. A third bent seat 33 is sleeved on the front ends of the two pliers heads; a first torque mechanism is provided on the first pliers head 11, a second torque mechanism is provided on the second pliers head 21, and a bending moment mechanism is further provided at the rear end position between the two pliers heads.
[0026] Specifically, a first groove 51 and a second groove 52 formed by separating with a first partition plate 41 are provided on the inner side wall of the first pliers head 11, and a third groove 53 and a fourth groove 54 formed by separating with a second partition plate 42 are provided on the inner side wall of the second pliers head 21; one side of the first bent seat 31 is provided with a first arc groove 311, and the other side is provided with a first insertion block 312. One side of the second bent seat 32 is provided with a second arc groove 321, and the other side is provided with a second insertion block 322. When the two pliers heads are clamped, the first groove 51 and the third groove 53 enclose to form a first connection hole for the first insertion block 312 to insert, and the second groove 52 and the fourth groove 54 enclose to form a second connection hole for the second insertion block 322 to insert.
[0027] A cutting edge is provided on one side of the first partition plate 41, and a cutting edge is also provided on the side of the second partition plate 42 facing the first partition plate 41. When the two pliers heads are clamped, the two cutting edges approach each other to achieve the purpose of cutting the arch wire.
[0028] The front ends of the first pliers head 11 and the second pliers head 21 are both inclined surface sections with the front end lower and the rear end higher. When the two pliers heads are clamped, the front ends of the two pliers heads are joined together to form a tapered block with a narrow front and a wide rear. A tapered hole 332 for the tapered block to be inserted and adapted is provided on one side of the third bent seat 33, and a third arc groove 331 is provided on the other side of the third bent seat 33.
[0029] The first torque mechanism includes a first opening groove 61 provided on the outer side of the first pliers head 11, and a first insertion pin 71 inserted into the first opening groove 61 at a position corresponding to the first opening groove 61 on the first pliers head 11; the second torque mechanism includes a second opening groove 62 provided on the outer side of the second pliers head 21, and a second insertion pin 72 inserted into the second opening groove 62 at a position corresponding to the second opening groove 62 on the second pliers head 21. The diameter of the second insertion pin 72 is larger than the diameter of the first insertion pin 71.
[0030] The bending moment mechanism includes a forming groove 10 provided inside the first jaw 11 and a forming protrusion 20 provided at a position corresponding to the forming groove 10 on the second jaw 21. During use, the two jaws are clamped, and the forming protrusion 20 extends into the forming groove 10 to achieve bending and forming of the arch wire.
[0031] Anti-slip sleeves 12 are sleeved on the outer sides of the first jaw arm 1 and the second jaw arm 2; a compression spring 13 is connected between the first jaw arm 1 and the second jaw arm 2.
[0032] The working principle of the present utility model is as follows:
[0033] As Figures 1 to 4 shown, when the overall contour of the arch wire needs to be bent and formed, according to the alveolar shape of the patient, the corresponding first bending seat 31, second bending seat 32 and third bending seat 33 are selected, and then the first jaw arm 1 and the second jaw arm 2 are firmly held, the compression spring 13 is squeezed and the first jaw 11 and the second jaw 21 are brought together and abutted. Thus, the first groove 51 and the third groove 53 enclose a first connection hole for inserting the first insert block 312, and the second groove 52 and the fourth groove 54 enclose a second connection hole for inserting the second insert block 322. The first bending seat 31 and the second bending seat 32 are symmetrically inserted at the left and right ends of the two jaws, and the front ends of the two jaws are brought together to form a tapered block with a narrow front and a wide rear. One side of the third bending seat 33 is sleeved outside the tapered block by a tapered hole 33. Then, the arch wire is sequentially placed into the first arc groove 311, the third arc groove 331 and the second arc groove 321, and the arch wire is bent and clamped into shape; when contour forming is not required, the three bending seats are removed, so as to use the present utility model to perform corresponding forming processing on the arch wire.
[0034] If a hole needs to be bent in the arch wire, taking the first torque mechanism as an example for illustration, first insert the first pin 71 into the first jaw 11 and extend it into the first opening groove 61, then bend and wind the position of the hole in the arch wire around the outside of the first pin 71, and then wind one end of the arch wire for one week to form a hole shape. At this time, the first pin 71 is taken out, and the arch wire is also taken out immediately, and then the opening position of the hole bent and formed is clamped and fixed by the positions of the two jaws; for the second torque mechanism provided, since the diameter of the second pin 72 is larger than the diameter of the first pin 71, it is for processing bent holes of other specifications; in addition, if a square hole needs to be bent, the first pin 7 and the second pin 72 are adapted to be changed to a circular inscribed rectangle structure at the insertion position, and the use is flexible.
[0035] If the arch wire is to be directly extruded and bent into shape, place the arch wire between the two jaws at the position corresponding to the forming groove 10, and directly pull the jaw arm. The forming protrusion 20 extends into the forming groove 10, thus realizing the extrusion and bending of the arch wire into shape. Since the bent shapes are diverse, including square and "Ω" shapes, for convenient replacement, the forming protrusion 20 should be adaptively inserted on the inner wall of the second jaw 21.
[0036] After the forming is completed, loosen the jaw arm, place the position where the arch wire needs to be cut at the position of the first partition 41, then hold the two jaw arms tightly, and the cutting edges on the first partition 41 and the second partition 42 approach each other to achieve the purpose of cutting the arch wire. The clamping principle for the rest of the related bending and shaping is the same as that of the prior art and will not be elaborated here.
[0037] The processes of multiple bending and shaping can all be completed by operating on one pair of pliers, which is flexible and convenient to use, saving the cost of configuring multiple pairs of pliers.
