The inner side of the edge is provided with a symmetrical cutting knife, and the outer sides of the upper pliers head and the lower pliers head are respectively provided with mutually matching protrusions and grooves, the top of the raised cross section is at right angles, and the grooves are at right angles. The cross-section is a right-angled triangle suitable for the protrusion. The invention is simple in structure, low in cost, and convenient to use. In the wiring work of the secondary line, it integrates shearing, stripping, and bending into a fixed angle, which saves time and effort, improves work efficiency, and performs standardized operations. The waste of the secondary line is reduced, and the economic benefit of the enterprise is improved.

Description

A new type of bending and stripping pliers

technical field

The invention relates to an improvement of a wire stripper, in particular to a new type of bending wire stripper, which is suitable for use in metering, meter installation, and electrical connection work, and can cut, strip and bend secondary wires.

Background technique

Electric energy metering is the "scale beam" between the power company and the electricity customer. The wiring standards and wiring process requirements for electric energy metering are getting higher and higher, especially whether the secondary line wiring is correct and firm, whether the wiring is reasonable, and the workmanship is beautiful All have higher requirements, but in the installation of the secondary wire for electric energy measurement, the wiring, bending and other processes are all done manually by a general-purpose wire stripper. This wire stripper is composed of a pliers head, a rotating shaft and a handle. The two handles are hinged and fixed by a rotating shaft. The front end of each handle is fixed with a pliers head, and symmetrical stripping heads are provided on the opposite edges of the two pliers heads. The two wire stripping knives buckled together The head snaps over the wire, cuts the insulation and strips it. Its shortcoming is: this kind of wire stripper can only be used for a single wire stripping work, can not carry out cutting and breaking work, can not carry out bending work, and the joint of the secondary wire after stripping is generally all done manually by hand. Bending is highly random, resulting in irregular wiring, high labor intensity and low work efficiency.

Contents of the invention

The purpose of the present invention is to provide a new type of bending that is simple in structure, low in cost, easy to use, integrates shearing, stripping and bending into a fixed angle in the wiring work of the secondary line, and saves time and effort. Wire strippers.

In order to achieve the above object, the technical solution of the present invention is: the novel bending wire stripper includes a handle, a rotating shaft, an upper pliers head, a lower pliers head and a wire stripping cutter head, the two handles are hinged as one through the rotating shaft, and the two The front ends of the two handles are respectively fixed with an upper pliers head and a lower pliers head, and a symmetrical stripping cutter head is arranged on the opposite edge of the upper pliers head and the lower pliers head. It is characterized in that: a spring is fixed between the two handles, Symmetrical cutting knives are arranged on the inner sides of the opposite edges of the upper tongs and the lower tongs. The outer sides of the opposite edges of the upper tongs and the lower tongs are respectively provided with mutually matching protrusions and grooves. The top of the cross section is a right angle, and the cross section of the groove is a right triangle matching the protrusion.

The effective effect of the present invention is: simple structure, low cost, easy to use, in the wiring work of the secondary line, it integrates cutting and breaking, stripping and bending into a fixed angle, saving time and effort, and improving work efficiency , to carry out standardized operations, reducing the waste of the secondary line and improving the economic benefits of the enterprise.

Detailed ways

Make the present invention with reference to Fig. 1, Fig. 2, Fig. 3. This new type of bending wire stripper includes a handle 1, a rotating shaft 2, an upper pliers head 3, a lower pliers head 9 and a wire stripping cutter head 6. The two handles 1 are hinged together through the rotating shaft 2. The front ends of the two handles 1 The upper pincer head 3 and the lower pincer head 9 are respectively fixed, and a symmetrical wire stripping cutter head 6 is arranged on the opposite edge of the upper pincer head 3 and the lower pincer head 9, and it is characterized in that: a fixed set between the two handles 1 Spring 5, so that when not in use, spring 5 can stretch two handles 1 under the action of its own elastic force, and the inner side of the relative edge of upper jaw 3 and lower jaw 9 is provided with a symmetrical cutter 4, and the wire can be cut by cutter 4 , the outer sides of the relative edges of the upper pincer head 3 and the lower pincer head 9 are respectively provided with mutually matching protrusions 7 and grooves 8, the top of the cross section of the protrusion 7 is a right angle, and the cross section of the groove 8 is A right-angled triangle suitable for the protrusion 7, so that when the secondary line connector is placed on the top of the protrusion 7, the groove 8 is pressed down, and the wire can be bent into a right angle, which is convenient for wiring operation and makes all the wires The structure will be bent into the same angle, which becomes a standardized operation.

When the invention is used, the secondary wire is first cut, then the joint is stripped, and finally the bending operation is performed, which saves time and effort, standardizes the operation process, and improves the work efficiency of the secondary wire.
