Versatile varieties of pliers
The number of designs of pliers is determined only by the number of objects of use( plumbing, electrical and other work).The dimensions of the tools can also vary for ease of use( the most common - from 125 to 220 mm).Of the entire family of such tools, universal pliers were combined, often called pliers.
This is a very common kind of hand tool. Their sponges have workers with notches of the gripping surface for flat and round objects and details, which is convenient for different jobs. On the inner side of the jaws there are also long cutting edges that allow working with a thick cable, cutting edges for different wires, including piano strings, are made on the two outer sides of the hinged connection.
On the inner side of the jaws there are serrated roundings to hold small parts. The material of production is a special tool steel, which allows hardening of the cutting edges and gripping jaws by hardening.
The desire to increase the number of operations that can be performed by a single combined tool has generated a variety of versatile pliers. Very often they have a complex sponge shape with several retention zones and pointed ends for fine grippers.
Their handles resemble a pair of Swiss folding knives, with saws, screwdrivers, blades, nests for replaceable attachments and even impact surfaces allowing to hammer a nail. In addition, the handles often have a coating of dielectric materials. In fact, such a combined tool is a small pocket traveling workshop.
We choose a tool for a fisherman and an electrician
Very often a need for such an instrument arises on a hike, on holiday or on a fishing trip. Every fan of "quiet hunting" knows annoying moments, when the fish has deeply swallowed the hook with bait and getting it becomes problematic. It happens that you need to immediately fix the ring or bushing on the rod, cut the wire or line, in general, fishing pliers will come just in time.
Given the specifics of the application, such a tool must have anti-corrosion properties, be light enough and versatile. The produced samples are made of aviation aluminum and stainless steels, often have removable jaws with hooks, grippers and cutting edges.
Pliers for the winding rings, as a more specialized tool of the fisherman, allow, thanks to a special device on one of the sponges, to quickly and easily change hooks of baits, make and change loops and rings, perform other urgent operations. Most models have a comfortable soft covering of spring-loaded handles, a special removable loop for carrying on the arm and small sizes.
Dielectric pliers used for electrical work differ, most often, only by the presence on the handles of special electrical insulation coatings or nozzles. Depending on the purpose, the insulating material can withstand a different voltage value, necessarily specified by the manufacturer.
In addition, during operation such a tool must undergo periodic verification by testing the dielectric to breakdown. Do not use tools with cracks or other damage to the electrical insulation of the handles.
Other specializations of pliers
A variety of the above tools can be considered crimping pliers. The majority is used for work with network power supplies and communication( information) cables. In this regard, the handles they have a reliable electrical insulation, and the jaws are made with teeth and samples that allow you to work with a certain set of cable diameters.
In addition to crimping functions, many samples, thanks to special cutting edges( often with the indicated size marking), can remove insulation without damaging the metal braid or wire. This design allows you to quickly, with high quality perform several operations in a single pass.
Another, quite specific area of application of the instruments under consideration is the fine arts. Someone has to make a stretcher, on which you need to stretch the canvas, to do it evenly, without folds, misalignments. It is absolutely necessary for these works to use pliers or pliers to stretch the canvas, having a special shape, a sufficiently large length( up to 23 cm) and wide( about 12 cm) flat sponges.
Without them it is difficult to fulfill this crucial part of the preparation of the future masterpiece. In the baguette workshops, tools made even from hardwoods are used, such tongs have special metal lining on the lips.
Special design allows you to use pliers peremstavnye at the time of clamping objects and parts with different thickness or diameter. The presence on the movable lever of the figured hole and the flat hinge axis, pressed into the stationary lever, allow to change the distances between the jaws with the cutting edges for snacking the wires.
Often a special set of pliers may be required to perform specific operations. For example, for radio installation work, tools of different sizes are needed with conventional and elongated jaws( with notches and without), called "platypuses", etc. Modern industry offers a wide range of such sets.
