Description

Pliers of rotation type wire stripping

Technical Field

The utility model relates to an electrician tool, in particular to a pair of rotary wire stripping pliers.

Background

In the process of line erection, the wire stripper is a common tool, is mainly used for stripping a wire insulating layer when a wire is lapped and connected, and has the following problems: the first wire stripper and the prior wire stripper are composed of two blades, the blades are made of tungsten steel, and after the wire stripper is used for a period of time, gaps can be formed on the blades; secondly, the existing blade is fixed by adopting a self-tapping screw, and the screw is easy to loosen to cause the blade to shake, so that an operator can hardly grasp the blade, and the situation that an aluminum wire is cut or even broken strands often occurs; thirdly, the blade of current wire stripper is horizontal, and is vertical for one, and the chucking department of blade is the triangle-shaped groove, is unfavorable for chucking wire. For the above reasons, the existing wire stripper only works on wires with soft outer layers, and has no way to achieve smooth stripping on wires with hard insulating layers, so that the skill and physical quality of operators on the poles are extremely tested. The power supply reliability is also greatly affected because the work cannot be completed in a short time.

Disclosure of Invention

The utility model aims to provide rotary wire stripping pliers which can strip wires rapidly and is not easy to damage core wires of wires.

In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme:

the rotary wire stripping pliers comprise a first body and a second body which are mutually hinged, wherein the first body and the second body are provided with semicircular grooves with opposite openings, and S-shaped blades are connected in the grooves;

the blade comprises a first blade connected to the lower surface of the first body and a second blade connected to the upper surface of the second body, and the first blade and the second blade are opposite in position;

the tail ends of the first body and the second body are fixedly connected with handles.

Further, the first blade and the second blade are respectively connected with the first body and the second body through anti-reverse locking screws.

Further, the first body and the second body are hollow semi-cylinders.

Further, the handle is sleeved with an insulating sleeve.

Further, the first blade and the second blade are each made of high carbon steel.

The utility model has the following beneficial effects:

when the wire is positioned in the semicircular groove, the first body and the second body of the wire stripper are mutually close to enable the insulating layer of the wire to be in contact with the S-shaped blade, and then the pliers are rotated along the circumferential direction of the wire, and the first blade and the second blade which are opposite up and down are matched to cut the insulating layer so as to realize wire stripping. Therefore, the utility model adopts the principle of rotating the cutting line, and the S-shaped blade can be used for easily stripping the insulating layer without damaging the core wire of the lead.

The distance between the first blade and the second blade can be adjusted through the anti-reverse locking screw, so that the pliers can be suitable for wires with different thicknesses, the anti-reverse locking screw is not easy to loosen, the fastening precision of the wire can reach 0.1mm, and the core wire of the wire is not easy to be hurt. The first body and the second body are directly designed into hollow semi-cylinders, so that a cavity for accommodating the lead and the S-shaped blade is formed, and the position of the blade can be conveniently adjusted; secondly, the portable and portable device is lighter and easier to carry. The blade made of high-carbon steel has high hardness, is sharper, is not easy to generate gaps, and has longer service life.

Detailed Description

The following examples are given to illustrate the present utility model in further detail, but are not to be construed as limiting the utility model thereto.

As shown in fig. 1-3, a rotary wire stripping pliers comprises a first body 1 and a second body 5 hinged with each other, wherein the first body 1 and the second body 5 are hollow semi-cylindrical so as to form semicircular grooves with opposite openings, S-shaped blades 3 are connected in the grooves, each blade 3 comprises a first blade 31 connected to the lower surface of the first body 1 and a second blade 32 connected to the upper surface of the second body 5, the first blade 31 and the second blade 32 are opposite, when wire stripping is needed, a wire is firstly positioned in a cavity formed by the semicircular grooves of the first body 1 and the second body 5, then the first body 1 and the second body 5 are mutually close to each other, the knife edges of the first blade 31 and the second blade 32 are tightly attached to an insulating layer of the wire, then the pliers are rotated around the circumference of the wire, the insulating layer of the wire is scratched so as to strip, and the cut depth is consistent during wire stripping.

The first blade 31 and the second blade 32 are respectively connected with the first body 1 and the second body 2 through the anti-reverse locking screw 4, so that the distance between the first blade 31 and the second blade 32 can be adjusted through the anti-reverse locking screw 4, and the pliers are suitable for wires with different thicknesses, and through practical tests, the pliers in the embodiment are suitable for wires with the cross section area of 25-70mm ² And the fastening precision of the lead can be realizedThe thickness reaches 0.1mm, and the core wire of the lead is not easy to be damaged.

The tail ends of the first body 1 and the second body 5 are fixedly connected with a handle 2, and the handle 2 is sleeved with an insulating sleeve, so that the use of staff is facilitated.

In this embodiment, the first body 1 and the second body 5 are hinged by a rotation shaft in the same manner as the common pliers on the market.

Preferably, the first blade 31 and the second blade 32 are both made of high carbon steel, have higher hardness and sharpness, have longer service life, and are not easy to be notched.

The working principle of the utility model is as follows:

when the anti-reversion type locking screw is used, the distance between the first blade 31 and the second blade 32 is adjusted through the anti-reversion type locking screw 4 according to the thickness of a wire, when the wire is positioned in a cavity formed by the first body 1 and the second body 5, the first body 1 and the second body 5 are close to each other, the knife edges of the first blade 31 and the second blade 32 are tightly attached to the insulation layer of the wire, and then the pliers are rotated around the circumference of the wire, so that the insulation layer of the wire is scratched and peeled off.
