Use of pliers
Do not use the pliers handle as a clamp head. Remember, remember.
The use of pliers is done with the right hand. With the jaws facing inward, it is convenient to control the jaw cutting position. Use the little finger to reach the middle of the two jaws to resist the jaw handle and open the jaws so that the jaws are flexible.
Wire cutters commonly used by electricians are available in various sizes such as 150, 175, 200 and 250 mm. It can be purchased according to the internal or external work types. The pinion of the pliers can also be used to tighten or loosen the nut.
The knife edge of the pliers can be used to cut the rubber or plastic insulation of the flexible wire.
The knife edge of the pliers can also be used to cut wires and wires. When cutting the 8th galvanized iron wire, use the blade to cut back and forth around the surface, and then just pull the wire and the wire is broken.
The cornice can also be used to cut hard wires such as wires and wires.
The insulating plastic tube of the pliers has a withstand voltage of 500V or more, and it can electrically cut the electric wire. Do not throw in the use, so as not to damage the insulated plastic tube.
Never use the pliers as a hammer.
It is not possible to cut double-stranded live wires with pliers and it will be short-circuited.
When the clamp is used to wrap the clamp to secure the cable, the forceps pinch the wire and wind it in a clockwise direction.
A nipper, commonly known as a needle-nosed pliers, is also one of the tools commonly used by electricians, especially insiders. It is mainly used to cut single-strand and multi-strand wire with thin wire diameter and to bend the single-strand wire joint and peel off the plastic insulation layer.
The operation method of bending the wire joint with the needle-nosed pliers is as follows: firstly, the thread head is folded to the left, and then the screw is bent rightward in the clockwise direction, that is, the needle-nosed pliers is slightly modified, and the needle-nosed pliers can be used for stripping.
The method is: use the electric drill to drill two slots of 0.8 and 1.0mm in the front section of the cutting edge of the needle-nosed pliers, and then slightly expand the drill with 1.2 and 1.4mm respectively. Note: Do not expand, so that the two slots There is a thin edge. In this way, a needle-nosed pliers that can be cut and stripped can be changed! Wire strippers are one of the commonly used tools for internal electricians, motor repairs, and instrumentation electricians. It is suitable for the stripping of plastic, rubber insulated wires and cable cores.
The method is as follows: the thread to be peeled is placed in the cutting edge of the clamp head, and the two clamp handles are pinched by hand, and then loosened, the insulation skin is disengaged from the core wire.
Pliers are a tool used for fastening, and some pliers also have a cutting function. There are many types of pliers, but they all have a part for clamping the material, called the "jaw." The jaws are controlled by a lever and can generate a large clamping force.
How to use pliers:
1 In general, the strength of the pliers is limited, so it is not possible to use it to perform work that cannot be achieved by the power of the general hand. In particular, the smaller or ordinary needle-nosed pliers may damage the jaws when it is bent with a strong bar.
2 The general crepe has three cutting edges, which can only be used to cut the wire and cannot be used to cut the wire.
3 The clamp handle can only be held by hand, and it cannot be applied by other methods (such as hitting with a hammer, using a bench vise, etc.).
