Technical Field

The invention relates to the technical field of shearing tools, in particular to a live cable cutting tool.

Background

In the case of emergency rescue of an electric vehicle or the like, it is sometimes necessary to cut off a high-voltage live cable. Current cable shearing tool is with pressure shearing cable, and when shearing electrified cable, the metal material and the cable of shearing tool cutting knife blade portion take place to electrically conduct, lead to cable shearing tool electrified, can cause shearing tool operating personnel to have the risk of electrocuteeing like this.

Disclosure of Invention

The invention aims to solve the technical problem of providing a live cable cutting tool which is convenient to operate and use, safe and reliable and free of electric shock risk.

In order to solve the technical problems, the technical scheme of the invention is as follows: the live cable cutting tool comprises two symmetrically arranged insulating clamp bodies with the middle parts pivoted, wherein one end of each insulating clamp body is a clamp head, and the other end of each insulating clamp body is a clamp handle; a cutting grinding wheel for cutting the live cable is rotatably mounted on one of the two clamp heads, the cutting grinding wheel is connected with a driving motor, and a cable limiting structure is arranged on the other clamp head and positioned on the inner side of the clamp head; and a tension spring is arranged between the two forceps handles.

As a preferred technical scheme, the cable limiting structure is a limiting groove arranged on the inner side of the binding clip.

As a preferable technical scheme, the two tong heads are both in a U-shaped structure, and the cutting grinding wheel is arranged in a U-shaped groove of one of the tong heads.

Due to the adoption of the technical scheme, the invention has the following beneficial effects: the grinding wheel which drives the high-speed rotation by the motor cuts off the high-voltage electrified cable, the grinding wheel is made of insulating materials and is non-conductive, the clamp handle and other exposed surface parts of the clamp body are all coated in an insulating mode and are non-conductive, a spring tension self-fastening function is arranged behind the clamp cable of the tool, a clamping operator can loosen the hand to operate and does not contact with the tool, and therefore the tool has no electric shock risk to the operator, and the tool is convenient to operate and use, safe and reliable.

Detailed Description

The invention is further illustrated below with reference to the figures and examples. In the following detailed description, certain exemplary embodiments of the present invention are described by way of illustration only. Needless to say, a person skilled in the art realizes that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

As shown in fig. 1 to 3, the live cable cutting tool includes two symmetrically arranged insulating clamp bodies 2, the middle of each insulating clamp body is pivoted through a rotating shaft 1, and the insulating clamp bodies 2 can be made of metal substrates to cover insulating layers to realize insulation or can be made of insulating materials directly; one end of the insulating clamp body 2 is a clamp head 21, and the other end of the insulating clamp body 2 is a clamp handle 22; a cutting grinding wheel 4 for cutting the live cable 3 is rotatably mounted on one of the clamp heads 21, the cutting grinding wheel 4 is connected with a driving motor 5, and a cable limiting structure is arranged on the other clamp head 21 and positioned on the inner side of the clamp head; in order to facilitate processing and use, the cable limiting structure in this embodiment is a limiting groove 6 disposed inside the binding clip, and certainly, other limiting structures such as a limiting column and the like may be adopted to realize the limiting function of the cable, which is not described herein again; and a tension spring 7 is arranged between the two forceps handles 22, and when the forceps handles are not acted by external force, the tension spring 7 naturally tensions the two forceps handles 22.

Referring to fig. 3, in this embodiment, the two binding clip 21 are both in a "U" shape, and the cutting wheel 4 is installed in the "U" shaped groove of one of the binding clip 21, so that two limiting grooves are formed on the binding clip along the axial direction of the cable, which is beneficial to stable limiting of the cable, and the cable is conveniently cut off by the grinding wheel rotating at high speed.

The use method of the tool comprises the following steps: referring to fig. 1 to 3, an operator grasps the forceps handle 22, and outwards applies force to open the two forceps heads 21, so as to place the live cable 3 to be cut at the position of the limiting groove 6; the operator stops exerting force, the two clamp heads 21 are tensioned and closed under the action of the tension spring 7, the cutting grinding wheel 4 keeps proper cable force pressing force due to the tension of the tension spring 7, and the live cable 3 is kept clamped by the cutting grinding wheel 4 and one of the clamp heads 21; the operator loosens the clamp handle 22, the cutting grinding wheel 4 generates internal rotation power by the driving motor 5, and the grinding wheel rotates to cut off the cable to be cut.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the invention should fall within the protection scope of the invention.
