[0033] Combine Figures 1 to 3 As shown, the utility model discloses a tool pliers with a rotatable wire splitting knife, comprising:

[0034] Tool pliers body 1;

[0035] A tool holder 2 is rotatably disposed on the tool pliers body 1;

[0036] A wire splitting knife 3, which is fixed on the knife seat 2;

[0037] A positioning portion 4 is connected to the tool pliers body 1 and is arranged opposite to the wire splitting knife 3, with a space between the positioning portion 4 and the wire splitting knife 3 for the power supply line to pass through;

[0038] The knife seat 2 rotates under the action of external force, so that the blade of the wire-splitting knife 3 rotates.

[0039] Compared with the prior art, the tool pliers disclosed in the present invention, when the knife holder 2 is rotated, the wire splitting knife 3 rotates with the knife holder 2, so that the blade angle of the wire splitting knife 3 changes. This is suitable for longitudinal cutting of the outer skin of the wire along its length direction and transverse cutting along the cross-section direction of the wire, openings of different angles or directions can be opened, and the outer skin of the wire can be completely separated from the wire core, which is convenient for the staff to operate.

[0040] In one embodiment, a groove 11 for installing the knife seat 2 is provided on one side surface of the tool pliers body 1, and the groove 11 is arranged close to the wire splitting knife, and the side of the groove close to the wire splitting knife is connected to the wire splitting knife; the bottom surface of the groove 11 has a threaded hole 12 connected to the other side of the tool pliers body 1; a fastener is threadedly connected to the threaded hole 12, so that the end of the fastener maintains a pressing effect on the knife seat 2, and then the position of the blade is fixed by fixing the position of the knife seat 2, thereby avoiding unnecessary rotation of the blade during cutting the outer skin of the wire.

[0041] In one embodiment, a protruding handle portion is provided on the knife holder 2 , and the handle portion is located in the groove 11 , so that the staff can rotate the knife holder 2 by acting on the protruding handle portion, making it convenient for the staff to rotate the knife holder 2 .

[0042] Furthermore, the handle portion includes a first handle portion 211 and a second handle portion 212, and the first handle portion 211 and the second handle portion 212 are arranged vertically; wherein, when the first handle portion 211 abuts against the bottom surface of the groove 11, the wire splitting knife 3 is in a longitudinal cutting position, so that the wire splitting knife 3 cuts the outer skin of the wire along the length direction of the wire; when the second handle portion 212 abuts against the bottom surface of the groove 11, the wire splitting knife 3 is in a transverse cutting position, so that the wire splitting knife 3 cuts the outer skin of the wire along the cross-sectional direction of the wire. In the present utility model, a first transverse cutting opening is first cut on the wire, and then a longitudinal cutting opening along the length direction of the wire is cut along the first transverse cutting opening according to its own needs, and finally a second transverse cutting opening is cut at the tail end of the longitudinal cutting opening to achieve complete separation of the outer skin of the wire and the wire core.

[0043] It should be noted that, when there is no fastener to fix the position of the tool holder 2 , the staff can use their hands to act on the first handle portion 211 and the second handle portion 212 to fix the position of the tool holder 2 .

[0044] Furthermore, the positioning part 4 can be a rotating part or a fixed part;

[0045] When the positioning part 4 is a rotating part, the positioning part 4 is a rotating wheel, and the surface of the rotating wheel is a concave arc surface; the rotating wheel is rotatably connected to the tool pliers body 1; in this way, when the wire is passed between the positioning part 4 and the wire splitting knife 3, the rotating wheel rotates due to the force of the wire, and the friction between the wire and the positioning part 4 is rolling friction, and the friction force is small, which is conducive to the staff moving the tool pliers when cutting the outer skin of the wire, and facilitates the staff's operation.

[0046] When the positioning part 4 is a fixing part, the surface of the fixing part opposite to the wire splitting knife is a concave arc surface, and the fixing part can be integrally connected to the tool pliers body 1 and become a part of the tool pliers body 1, thereby simplifying the structure of the tool pliers body 1; the fixing part can also be detachably connected to the tool pliers body 1, so that when the fixing part is worn, it can be replaced in time.

[0047] In one embodiment, the tool pliers body 1 has two pliers bodies 13, and the two pliers bodies 13 are connected in an "X" shape; with the rotation center of the two pliers bodies 13 as a reference, an upper functional area 14 and a lower functional area 15 are respectively formed in the middle of the two pliers bodies 13; the wire dividing knife is located in the upper functional area 14 or the lower functional area 15.

[0048] Furthermore, in order to make the tool pliers have multiple functions, they can be applied to various electrical operations;

[0049] The upper functional area 14 and the lower functional area 15 are provided with at least one of a clamping portion 51 , a wire stripping portion 52 , a cutting blade portion 53 , a wire pulling portion 54 , and a terminal crimping portion 55 .

[0050] The caliper body 13 is provided with at least one of a wire winding hole 56 and a wire branching hole 57 .

[0051] The outer side of the pliers body 13 is provided with at least one of a file grinding portion 58 and a hexagonal screw nut portion 59 .

[0052] It should be noted that the structural structures of the above-mentioned clamping part 51, wire stripping part 52, cutting blade part 53, wire pulling part 54, terminal crimping part 55, winding hole 56, branching hole 57, file grinding part 58, and hexagonal screw nut part 59 are all existing technologies and will not be elaborated here.

[0053] Furthermore, the tool pliers with a rotatable wire splitter also includes a lock 16 for locking the two pliers bodies 13 after closing, so as to prevent the two pliers bodies 13 from opening due to shaking after the tool pliers are placed in a storage bag or storage box.

[0054] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.

[0055] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
