As shown in fig. 1, in the conventional bending process of the metal wire 200, the metal wire 200 is clamped at one end by using the nipper pliers, one hand grasps the other end of the metal wire 200, and the other hand bends the metal wire 200 by rotating the nipper pliers. The bending effect of the metal wire 200 is as shown in fig. 2, the bending angle of the metal wire 200 cannot be guaranteed, the requirement of a user is difficult to reach, and in addition, the operator wastes time and labor in the bending process, and the manual consumption is high.

For this reason, the embodiment of the present application provides a bending structure 100, a nipper pliers and a jawset, which can be used for metal working, particularly for angle bending of a metal wire 200. The bending structure 100, the nipper pliers and the pliers provided by the application can improve the bending efficiency of the metal wire 200, so that the metal wire 200 can achieve a stable forming effect.

It should be noted that the bending structure 100, the nipper pliers and the pliers provided by the application are not limited to bending the metal wire 200, but can be used for bending structures such as strip-shaped structures and tubular structures. For ease of understanding, the wire 200 is used as an illustration of a bending application in the present application.

As shown in connection with fig. 3 and 4, an embodiment of the present application provides a bending structure 100, the bending structure 100 comprising two bending members 110. The bending piece 110 includes a force receiving portion 111 and a fulcrum portion 112, one end of the force receiving portion 111 is connected with the fulcrum portion 112, and the fulcrum portions 112 of the two bending pieces 110 are rotatably connected. The stress part 111 of one bending piece 110 is provided with a groove 1112, the stress part 111 of the other bending piece 110 is provided with a bending block 1111, the bending block 1111 is in butt fit with the groove 1112, one side of the bending block 1111 close to the groove 1112 is provided with a corner angle, and the corner angle is a preset included angle alpha.

Illustratively, the bending structure 100 includes two bending members 110 that are rotatably engaged with each other, and the bending members 110 may be metal bars with a certain hardness, so as to achieve a pressing bending effect on the metal wire 200. The force receiving portion 111 of the bending member 110 is a hand action point of an operator, and when the two bending members 110 are rotationally connected through the fulcrum portion 112, the bending member 110 may form a lever-like structure, and the two bending members 110 are pressed by hand to make the two bending members 110 close to each other.

Meanwhile, in the two bending members 110, a groove 1112 is provided on the force receiving portion 111 of one bending member 110, and a bending block 1111 is correspondingly provided on the other bending member, and the bending block 1111 and the groove 1112 are both disposed at the connection portion between the force receiving portion 111 and the fulcrum portion 112. Thus, when the wire 200 is placed in the groove 1112 and the bending block 1111 is pressed to bend the wire 200, the stress of the wire 200 is increased, the force applied by an operator is reduced, and the force is similar to the labor-saving lever principle.

Fig. 5 is a side view of the bending structure 100, and fig. 6 is an effect diagram of the metal wire 200 after being bent by the bending structure 100, as shown in fig. 5 and 6. The bending block 1111 is provided with a V-shaped corner on the pressing side of the wire 200, and the preset angle of the corner is α. In the bending process, the edge angle of the bending block 1111 presses the metal wire 200, so that the metal wire 200 is bent towards the inside of the groove 1112, and finally is attached to the edge angle of the bending block 1111, the bending angle reaches the preset angle alpha of the edge angle, the preset angle bending of the metal wire 200 is realized, and the ideal effect of an operator is achieved or is close to that of the operator.

As shown in fig. 5, in some embodiments, the notch of the groove 1112 is V-shaped, and the notch angle of the groove 1112 is a predetermined included angle β.

Illustratively, the V-shaped notch angle β of the groove 1112 is the same as the angular angle α of the bending block 1111, and when the bending block 1111 is located in the groove 1112, the angular angle of the bending block 1111 may be fitted to the groove surfaces on both sides of the groove 1112. In the bending process of the metal wire 200, the bending block 1111 applies force to the metal wire 200, so that the metal wire 200 bends towards the outer side of the groove 1112, and finally under the action of the bending block 1111, two ends of the metal wire 200 are attached to groove surfaces on two sides of the groove 1112 to form a preset angle alpha which is the same as the angle of the V-shaped groove opening, the bending effect of the metal wire 200 is improved, and the bending target of a user is achieved.

As shown in fig. 6, in one embodiment, the preset angle α and the preset angle β may each be 90 °.

The inventors of the present application have found that it is difficult to bend the wire 200 in a desired right angle form during the bending process of the wire 200, and time and cost are wasted due to the fact that the bending error requires multiple adjustments.

In this embodiment, by setting the angle of the bending block 1111 and the V-shaped notch of the groove 1112 to 90 °, during the bending process of the metal wire 200, when two sides of the metal wire 200 respectively abut against the side surface of the angle and the inner side wall of the groove 1112, the effect of bending the metal wire 200 to 90 ° can be achieved, and the desired effect of the user can be obtained.

In other embodiments, the preset angle α and the preset angle β may satisfy 30.ltoreq.α.ltoreq.150° and or 30.ltoreq.β.ltoreq.150°.

In the actual operation process, the target angle of the user may be changed, and the operator may obtain the required bending angle by setting the edge angle of the bending block 1111 and the V-shaped notch of the groove 1112 to the required preset angle, so as to finally obtain the metal wire 200 with the corresponding bending angle.

The preset included angle α may be 30°、35°、40°、45°、50°、55°、60°、65°、70°、75°、80°、85°、90°、95°、100°、105°、110°、115°、120°、125°、130°、135°、140°、145°、150° or the like.

Of course, the bending angle may not be limited to the above range, but in the actual operation, when the bending angle is too small, the wire 200 is easily broken due to the rigidity of the metal. When the bending angle is too large, the bending effect of the metal wire 200 is not obvious.

As shown in fig. 8, in one embodiment, bending structure 100 may be matched with a plurality of sets of ferrules 130 with different angles, ferrule 130 is in a V-shaped structure and may be sleeved in bending block 1111 and groove 1112, and the bending effect of bending block 1111 has been adjusted by the V-shaped groove angles of different ferrules 130, so as to implement the operation adjustment of multiple bending angles by one bending structure 100.
