Pliers are used in automotive repair tools to clamp, hold, bend or cut material.
There are many types of pliers, such as carp pliers, wire pliers, needle-nose pliers, flat-nose pliers, etc. Different types of pliers are suitable for disassembling and assembling different parts.
Carp pliers
Shape: The front part of the pliers head is flat and fine teeth, which is suitable for pinching small parts. The notch in the middle is thick and long, which is used to clamp cylindrical parts. Mouth cuts wire.
The use of carp pliers: There are two interpenetrating holes on a piece of pliers body, a special pin, the opening of the jaws can be easily changed during operation, so as to adapt to clamping parts of different sizes.
Wire cutters
The use of wire pliers is similar to that of carp pliers, but its support pin is fixed relative to the two pliers, so it is not as flexible as carp pliers when used, but the effect of cutting metal wires is worse than that of carp pliers. The specification is expressed by the length of the pliers.
Needle nose pliers
Because of its slender head, it can work in a small space. The one with a cutting edge can cut small parts. Do not use too much force when using it, otherwise the head of the jaw will be deformed or broken. The specification is expressed by the length of the jaw.
Flat nose pliers
It is mainly used to bend metal sheets and metal filaments into desired shapes. In repair work, it is often used to install and pull out pins, springs, etc.
Curved nose pliers
Also known as elbow pliers. It is divided into two types without plastic sleeve and with plastic sleeve on the handle. The purpose is similar to needle-nose pliers (without cutting edge), suitable for use in narrow or sunken working spaces.
Wire strippers
It can strip the insulation layer of plastic or rubber insulated wires, and cut common copper and aluminum core wires of different specifications.
Bolt cutters
A tool used to cut wire. Generally, there are insulating handle bolt cutters and iron handle bolt cutters, and there is also a pipe handle bolt cutter. Among them, electricians often use insulating handle bolt cutters. Bolt cutters are usually used to cut wires and cables.
Pipe Wrenches
A pipe wrench is a tool used to clamp and rotate steel pipes, clamping the pipe and turning it to complete the connection.
Finally: Some Notes on Using Pliers
1. Do not use pliers instead of a wrench to loosen the threaded connection above M5, so as not to damage the nuts or bolts;
2. When cutting the metal wire, be careful that the wire jumps out and hurts people;
3. Do not cut too hard or too thick metal, so as not to damage the pliers.
4. It is forbidden to disassemble the hexagonal bolts and nuts with pipe wrench, so as not to damage the hexagonal.
5. It is forbidden to disassemble and assemble high-precision pipe fittings with pipe wrench, so as not to change the roughness of the workpiece surface.
