What is a plier ?

Pliers Meaning

Pliers are a hand operated tools Which is used to handle and grip small objects or to bend and cut the wire.

What is pliers used for ?

Pliers come in a variety of shapes and sizes, and they have a wide range of applications. Some are designed to be used for gripping something round, such as a pipe or rod, while others are designed to be used for a variety of tasks, including cutting wire.

Different Types of pliers and their uses

The following are the various types of pliers and their applications:

A) According to the Standard types of pliers

1. Slip joint pliers

Slip joint pliers are type of pliers which fulcrum can be easily adjustable to alter the width of the jaw. Hence, Because of the movable fulcrum, the jaws’ size range can be easily increased.

Slip joint pliers ( Types of pliers )

These pliers have a flat and serrated tip. The jaws of the pliers are curved out just below the tip for gripping rounded surfaces such as pipes. Slip joint pliers are found in almost every toolbox.

Uses :- It is used to crimp metal, loop wire, and cut soft nails. Slip-joint pliers can also be used to loosen and tighten nuts and bolts.But not used for cutting the wire.

This is also known or called as Water pump pliers.

The bolt of the fulcrum has a variety of marks to slip into when the jaws are open, allowing you to lock to a specific width. They’re commonly used in plumbing applications and can perform a variety of tasks, similar to a wrench.

2. Hose Clamp plier

  • The lineman’s pliers’ tapered nose can be used to ream the rough edge.

14. Locking pliers

These pliers are designed to lock the jaws in place, making them useful for snatching screws and bolts.

An over-center toggle action is used in the locking pliers to lock into a specific position. The locking pliers have various uses in the manufacturing and design industries.

They are a very specific type of pliers that are sometimes referred to as Vise-Grips. William Petersen invented the first locking plier in the United States in 1924. Thomas Coughtrie invented Mole wrenches after the second type of locking pliers.

The mechanism involved in the locking pliers

The locking pliers are made up of two jaws. The bolt for adjusting the space between the jaws is housed in one of the handles. The lever for unlocking the pliers is located on the opposite side of the handle. The locking pliers are sold under the brand names Vise Grips and Mole.

In everyday life, mechanics in the United States refer to locking pliers as Vise-Grips, while mechanics in the United Kingdom refer to locking pliers as Mole Grips.

The bolt is used to tighten or loosen the jaws. They are kept in such a way that they are smaller than the object to be gripped.

The jaws are now fixed on the gripped object.

Advantages of locking pliers are

  • They can be used to generate more force because their lever action is far stronger than that of other types of pliers.
  • With the locking pliers, you can easily apply a controlled force.
  • The locking pairs can remain close without the need for human intervention.
  • Locking Pliers are useful for a variety of tasks.

Uses of locking pliers are :-

  • They are also used in processes where pin-style anchors are commonly used.

25. Wire twisting pliers

The jaws of wire twisting pliers are very short. It has two jaws and both of the jaws have a cutting edge.

A knob and a special cylindrical locking mechanism are located between the two handles of the wire twisting pliers.

By paying attention to the above description, we can easily identify the wire twisting pliers.

With the help of this locking mechanism, the entire wire spins and we get the required twisting. With the help of the wire twisting pliers, we can twist many wires at the same time. We can twist multiple wires at the same time using wire twisting pliers.

Uses of wire twisting pliers :-

  • Wire twisting pliers are used by electricians as well as in the electronics industry.
