[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art belong to the protection scope of the utility model.

[0030] The utility model discloses a handle 1 and plier mouth 2, two handle 1 that is left handle 1 and right handle 1 are connected around the pivot rotation, and the pivot is also the rotation point in the middle position of handle 1, and the top of two handle 1 is equipped with plier mouth 2, and plier mouth 2 includes left plier mouth 2 and right plier mouth 2, and left plier mouth 2 and right plier mouth 2 are located at the top of left handle 1 and right handle 1 respectively, and the working of plier mouth 2 is realized by the mutual rotation of two handle 1.

[0031] Each handle 1 comprises a base part 11 and a jaw 12, the base part 11 is usually a long strip-shaped plate structure made of metal, the two base parts 11 are rotatable relative to each other through a pin shaft, the base part 11 is divided into an upper half and a lower half by the rotation point, the jaw 2 is usually arranged on the upper half of the base part 11, and the jaw 12 is usually arranged on the lower half of the base part 11. The jaw 12 is usually made of plastic or rubber, and each base part 11 is provided with a jaw 12. The opposite sides of the two jaws 12 are respectively provided with mounting grooves 121, that is, the openings of the mounting grooves 121 are on the side surface. The openings of the mounting grooves 121 of the two jaws 12 are oppositely arranged. The base part 11 is inserted into the mounting groove 121 to form a plug-in assembly, that is, the two side surfaces of the mounting groove 121 are clamped on the two surfaces of the base part 11 to form a tight fit. One of the front and rear surfaces of the jaw 12 is provided with a mounting hole 122. The mounting hole 122 penetrates from the front or rear surface of the jaw 12 through the mounting groove 121 to the side surface away from the opening of the mounting hole 122, that is, the jaw 12 is divided into a front part and a rear part by the mounting groove 121. The mounting hole 122 penetrates from the front part to the rear part, but the rear part is not completely penetrated, only a blind hole is formed on the side surface of the mounting groove 121 of the rear part. The base part 11 is provided with a connecting hole 116 coaxial with the mounting hole 122. A positioning pin is inserted into the mounting hole 122 and penetrates the connecting hole 116, so that the mounting hole 122 and the connecting hole 116 are connected through the positioning pin. The bottom end of the positioning pin is inserted into the blind hole on the side surface of the mounting groove 121, so that the jaw 12 and the base part 11 are fixedly connected. It should be noted that the mounting hole 122 is located at the top of the jaw 12, and the top of the jaw 12 will not be separated from the base part 11 after long-term hand extrusion.

[0032] The base parts 11 of the two handles 1 are partially exposed outside the corresponding jaws 12. The exposed parts 111 of the base parts 11 of the two handles 1 are oppositely arranged, that is, the width dimension of the base part 11 is higher than the depth of the mounting groove 121, so that after the base part 11 is plug-in assembled with the mounting groove 121, part of the base part 11 is not covered by the jaw 12, that is, the exposed part 111 is formed. The opposite surfaces of the two exposed parts 111 are respectively provided with a pressing end slot 112 and a pressing end protrusion 113. The pressing end slot 112 and the pressing end protrusion 113 are engaged with each other to perform wire pressing work.

One side of the thickened plate 114 is provided with a groove 115 corresponding to and flush with the pressing end slot 112, and the other side abuts against the corresponding jaw 12. The two thickened plates 114 are attached to the exposed part 111 where the pressing end slot 112 is located, so that the width of the pressing end slot 112 is increased. In this way, after the wire is inserted into the pressing end slot 112, the front and rear of the wire are stably positioned and will not slide and deviate due to the extrusion of the pressing end protrusion 113.

[0033] It should be noted that the thickened plate 114 is mounted on the base body 11 by screws or bolts and the like fasteners to achieve detachable connection of the thickened plate 114.

[0034] The positioning grooves 123 are staggered on the two sides of the same mounting groove 121, and in this embodiment, the number of the positioning grooves 123 on each side is one. There is one protrusion 117 on each of the front and rear surfaces of each base body 11, so that the protrusion 117 is inserted into the positioning groove 123 to form a buckle positioning, which further strengthens the fixed connection between the plier pants 12 and the base body 11 and prevents the plier pants 12 from deforming or even separating from the base body 11 after long-term use.

[0035] In this embodiment, the positioning groove 123 is a square groove, and the protrusion 117 is a square protrusion. The edge of the protrusion 117 is chamfered to facilitate the insertion of the protrusion 117 into the positioning groove 123 during installation of the plier pants 12.

[0036] One of the plier pants 12 extends a hook portion 124 towards the surface of the other plier pants 12. The hook portion 124 extends from the plier pants 12 or is designed in one piece with the plier pants 12. The hook portion 124 is provided with a hanging hole 125, which facilitates the hanging of the entire electrician pliers.

[0037] In addition, the pressing end groove 112 includes a first type of pressing end groove 1121 and a second type of pressing end groove 1122. A plurality of first type of pressing end grooves 1121 and second type of pressing end grooves 1122 are equidistantly distributed along the length direction of the exposed portion 111. The size of each first type of pressing end groove 1121 is different, and the size of each second type of pressing end groove 1122 is also different. The pressing end protrusion 113 includes a first pressing end protrusion 1131 and a second pressing end protrusion 1132. The first pressing end protrusion 1131 corresponds to the first type of pressing end groove 1121 one by one, and the second pressing end protrusion 1132 corresponds to the second type of pressing end groove 1122 one by one. The size of each first type of pressing end protrusion 113 is different, and the size of each second pressing end protrusion 1132 is also different.

[0038] In this embodiment, the number of the first type of pressing end groove 1121 is three, and the end surface thereof is a circular arc surface with a radius of 2.84 mm, 2.15 mm and 2.18 mm, respectively.

[0039] The number of the second type of pressing end groove 1122 is also three, and the end surface thereof is a circular arc surface with a radius of 2.64 mm, 2.06 mm and 1.47 mm, respectively.

[0040] The number of the first pressing end protrusion 1131 is three, and the end surface thereof is a circular arc surface with a radius of 0.71 mm, 0.65 mm and 0.55 mm, respectively.

[0041] The second pressing end protrusions 1132 are also three in number, and the end faces thereof are circular arc faces with a radius of 0.85mm, 0.68mm and 0.6mm respectively

[0042] When the three first pressing end notches 1121 and the three first pressing end protrusions 1131 are engaged one by one, the bottom end of the first pressing end notch 1121 and the top end of the first pressing end protrusion 1131 are spaced apart from each other by a distance of 0.78mm, 0.63mm and 0.49mm respectively.

[0043] When the three second pressing end notches 1122 and the three second pressing end protrusions 1132 are engaged one by one, the bottom end of the second pressing end notch 1122 and the top end of the second pressing end protrusion 1132 are spaced apart from each other by a distance of 0.49mm, 0.43mm and 0.4mm respectively.
