What are the parts of the end trimming pliers?

     

Jaws

The jaws of the end pliers are almost flat, which allows you to cut as close as possible to the surface of the workpiece. This leaves excess wire or nails lying flush with the surface rather than sticking up.They are very sharp and should fit exactly together without any gaps. Sponges for end pincers are made in two executions:

• Knee-joint
• box connection

Knee-joint

This is the most common type of connection for end pliers. One handle is superimposed on the other, connected by a central rivet. The downside is that with heavy use, the rivet can loosen over time, causing the jaws to move.

box connection

A box joint is when one side of the pliers slides through a slot made on the other side. The connection is much stronger because four tool surfaces are in contact, and not just two, as in a lap joint. The jaws have more support on the sides so they won't move and will cut more accurately. This is the strongest type of connection, but also the most expensive to manufacture.

Advanced

The pliers have very sharp cutting edges that allow you to cut through the wire. Heavy duty versions can even cut nails and bolts. The edges are beveled, which means that they gradually slope towards the tip. This gives additional strength, as the jaws are much wider than the cutting edges.

Point of support

The pivot point, also called the fulcrum, is the point around which the arms and jaws of the ticks rotate. It is usually a nut or screw.Many end pliers have two pivot points, known as double pivot points. This increases their cutting ability because the second pivot point works in conjunction with the first, creating much more force for the same amount of effort.

Pens

The handles act as levers to grip the jaws of the ticks. They vary in length and are usually covered in plastic, rubber, or a mixture of the two, often with lugs or grooves for extra grip. Handles with thick shock-absorbing coatings are more comfortable to use. Some pliers have shaped handles that flare at the top to keep fingers from slipping into sharp jaws.Others have more pronounced finger protection, called skid protection or thumb rests. As the name suggests, these are small protrusions built into the handle that help prevent the hand from slipping towards the sharp end while cutting or twisting.

Return spring

Smaller end trimming pliers that can be operated with one hand can be equipped with single or double return springs that automatically return the handles to the open position when you release them.

This reduces effort when performing repetitive tasks, and also allows you to firmly hold the workpiece in place with your other hand.
