Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable cutter having both a cutter portion capable of cutting a cable wire cleanly and a plier portion capable of gripping a tip end of the cable wire.

[0002]

2. Description of the Related Art For example, in the extension electric work, most of the work is cutting the cable and grasping the cable, but with conventional pliers and nippers, a flat cable (F cable) is used. ) Or soft copper wire with coating such as annealed copper stranded cable cannot be cut cleanly, and the tip of the cable wire cannot be grasped (grasped) by a cable cutter.

That is, conventionally, there has been no tool having both a cutting function (cutter part) and a pinching function (plier part), so that work efficiency is poor.

In view of the above situation, the present invention is capable of grasping a thin product, holding the tip of the cable wire with pliers, and using a cutting blade of a slidable cutter that slides and polymerizes to make a clean and soft cable. The purpose is to provide an excellent cable cutter that can cut even wires.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

[0006] The cross-polymerization portion of the pair of holding half bodies 1 is axially attached,
Pliers A are provided on the inner edges of the tip of the holding half 1 that is opened and closed to form the holding edge 2 for holding the ends of the holding half 1 that abut and abut each other when the tip of the half half 1 is closed. This pliers portion A at the tip of the half body 1 and the holding half body 1
The facing inner edges between the shaft mounting portions 3 are recessed outward, and the blade edge 5 is formed on the inner edge of the recessed portion 4, and the tip end of the holding half body 1 is closed to operate the pliers A. Before the two contacting edges 2 of the holding contact each other against each other, the tip ends of the blade edges 5 of the inner edge of the recessed portion 4 are first polymerized with each other to form a closed opening 6 between the blade edges 5 and further closed. As the operation progresses, the blade edge 5 on the pivotal base end side is further superposed from the tip end side, and the opening area of the closing opening 6 becomes small, and the material 7 to be cut is inserted and arranged in the closing opening 6. Therefore, the cutter portion B is provided by setting the recessed shape of the recessed portion 4 so as to be sandwiched and cut by the blade edge 5 that gradually overlaps from the tip end side toward the pivotal base end side. The present invention relates to a cable cutter.

[0007]

[Function] The gripping portion 8 on the proximal end side of the holding half body 1 is held to close the distal end side members of the holding half body 1, and the pliers A provided at the tip end of the holding half body 1 for holding the holding half body 1. By bringing the contacting edges 2 into contact with each other, even a thin object can be held by the holding contacting edge 2.

When a material 7 to be cut such as a cable wire is arranged between the opposing blade edges 5 of the cutter portion B and the closing operation is performed,
It is introduced into the closed opening 6 formed by the opposing blade edges 5, surrounded by the blade edge 5, and further closed to gradually close the blade edge 5 toward the proximal end pivot portion. And the opening area of the closed opening 6 becomes small, and the blade edge 5 that is going to be overlapped cuts well.

[0009]

EXAMPLE In this example, the opposing inner edges of the cross-overlap portion of each holding half body 1 on the side slightly distal to the tip end side are recessed in a V shape to form a recessed portion 4, and this recessed portion is formed. One of the inner edges of the portion 4 is inclined and polished to form an inclined surface 5A, and the blade edge 5 is formed on this inner edge.
The other is formed as a flat mating sliding surface 5B having a step at the tip that overlaps with the inclined blade edge 5, and the blade edge 5 is formed at the inner edge thereof. Since this flat mating sliding surface 5B is subjected to precision mechanical polishing finish, the blade mating can be precisely slid to be cut cleanly.

Therefore, in the present embodiment, when grasping the tip of the cable wire, the gripping portion 8 on the proximal end side of the holding half body 1 is held and the leading end side of the holding half body 1 is actuated to close. The gripping abutment edge 2 of the pliers A formed by forming the facing inner edge of the tip of the body 1 on the uneven tooth edge for slip prevention is brought into abutting contact with each other, and thereby the sandwiching abutment edge 2 holds the body 1. While the pliers A for butting and abutting are provided, it is possible to cleanly cut the material 7 to be cut, such as an F cable or a soft copper stranded cable with a coating, such as a soft cable wire, with a holding force of one hand. It is configured such that a sliding and overlapping type cutter portion B is provided on the above.

Further, in this embodiment, since the butting gap of the holding contact edge 2 is designed to be zero, a thin object can be grasped.

Further, when a material 7 to be cut such as a cable wire is arranged between the opposing blade edges 5 of the cutter portion B and the closing operation is performed,
The blade is introduced into a closed opening 6 having a substantially triangular shape when viewed from the front, which is formed by both opposing blade edges 5, is surrounded by the blade edge 5, and is further closed to operate from the tip end side of the blade edge 5 to the base end. The opening area of the closing opening 6 is reduced by gradually superposing toward the pivoting portion side, and the pinching contact edge 2 of the pliers A is held.
When they are abutted against each other, the closed edge portion 6 is surrounded by the blade edge 5 and is satisfactorily surrounded by the blade edge 5 to be sandwiched and cut.

Further, in this embodiment, a blade groove 9 is formed opposite to the gripping base end side of the shaft attaching portion 3 of each holding half body 1, and the blade groove 9 is formed by crossing the blade grooves 9 so as to cross each other. Hard wires such as iron wires and wires to be placed in the can be easily cut without misalignment. A crimping operation can also be performed by providing a receiving recess 10 further on the grip base end side than the blade groove 9 of the one holding half 1 and a convex portion 11 engaging with the receiving recess 10 on the other holding half 1. I am trying.

[0014]

Since the present invention is configured as described above, even a thin product can be grasped, so that the tip of the cable wire can be held and a clean and soft cable wire can be obtained by the sliding type cutting blade which slides and polymerizes. It is an excellent cable cutter that can be easily cut.

In addition, even though the gripping holding function and the cutting function are combined, that is, the holding function is achieved, the cutting function is slid even though the holding abutment edges of the tips of the holding half bodies are in contact with each other. It is a combination polymerization method, and because it is constructed so that it can be cut by sliding and superposing it so that the material to be cut is surrounded by the edge of the blade, even thin objects can be grabbed and the coating of F cable and annealed copper stranded wire cable Even a soft cable line attached can be easily and cleanly cut, making it a very convenient cable cutter especially for electrical work.

Claims (1)

[Claims] 1. A pair of sandwiching halves is axially attached to a cross-polymerized portion,
Pliers are provided on the opposite inner edges of the tips of the holding halves that are opened and closed to form holding contact edges that abut and abut each other when the tips of the holding halves are closed. The facing inner edge between the pliers of the section and the shaft-attaching portion of the holding half is recessed outward, and a blade edge is formed on the inner edge of the recess, and the leading end of the holding half closes. Then, the tip ends of the blade edges of the inner edge of the recessed portion are first polymerized with each other until the pinching contact edges of the pliers come into abutting contact with each other, so that a closed opening is formed between the blade edges and further closed. As the operation progresses, the blade edge on the pivoting base end side is further overlapped from the tip end side to reduce the opening area of the closing opening portion. By inserting and arranging the material to be cut into the closing opening portion, the tip end side is inserted. From the above-mentioned recessed portion so as to be sandwiched and cut by a blade edge that gradually overlaps from the pivoting base end side. Cable cutter is characterized by providing a cutter unit by setting the recessed shape.
