Manual tool explanation: correct understanding and use of pliers

Today, I will introduce a very important molecular pliers in this big family of hand tools. Everyone knows that there are many types of pliers, including flat-nose pliers, diagonal pliers, wire cutters, diagonal pliers, needle-nose pliers, bolt cutters, power pliers, pipe pliers, punch pliers and so on. But they all have a part for clamping the material, called the jaw. The jaws are controlled by a lever, which can generate a large clamping force.

Nowadays, many people do not know how to correctly recognize and use pliers. The first thing to know is that using pliers is to operate with their right hands. With the jaws facing inward, it is easy to control the cutting position. Use your little finger to stretch the middle of the two pliers handles to resist the pliers handles, and open the pliers heads so that the pliers handles can be separated flexibly. How to use the pliers: ①Under normal circumstances, the strength of the pliers is limited, so you can't use it to operate tasks that can't be achieved by ordinary hand strength. Especially for smaller or ordinary needle-nose pliers, the jaws of the pliers may be damaged when they are used to bend high-strength bar materials. ②The general pliers have three cutting edges, which can only be used to cut iron wires and cannot be used to cut steel wires. ③The pliers handle can only be held by hand, and no other methods can be used to add force.

So how many kinds of pliers are there in daily life? Let me introduce to you first! The wire pliers commonly used by electricians have a variety of specifications such as 150, 175, 200 and 250mm. It can be purchased according to the needs of internal or external work types. The teeth of the pliers can also be used to tighten or loosen nuts. The knife edge of the pliers can be used to cut the rubber or plastic insulation layer of flexible wires. The knife edge of the pliers can also be used to cut wires and iron wires. When cutting No. 8 galvanized iron wire, use a knife to cut back and forth around the surface a few times, and then only need to pull it lightly to break the wire. The guillotine can also be used to cut hard metal wires such as electric wires and steel wires. The insulated plastic tube of the pliers can withstand a voltage of more than 500V, and it can cut wires with electricity. Do not throw it around during use to avoid damaging the insulating plastic pipe.
