Safe Use Of Pliers

Pliers are tools 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 materials called the "jaw". The jaws are controlled by a lever, which can generate a large clamping force. Let's learn about the safe use methods and rules of pliers together.
The usage method of pliers: ① In general, the strength of pliers is limited, so it cannot be used to operate tasks that cannot be achieved by ordinary hand force. Especially for smaller models or ordinary pointed nose pliers, using them to bend high-strength bar material sheets may damage the jaws A typical pliers have three cutting edges and can only be used to cut iron wire, not steel wire The handle of the pliers can only be held by hand and cannot be used to apply force by other methods (such as using a hammer, clamping with a vise, etc.).
Mouth pliers, commonly known as pointed nose pliers, are also one of the commonly used tools for electricians, especially for interior electricians. Mainly used for cutting thin single and multi strand wires, as well as bending single strand wire joints, peeling plastic insulation layers, etc. The operation method of bending the wire connector with pointed nose pliers is: first bend the wire end to the left, and then bend it clockwise to the right against the screw.
The pointed nose pliers can be slightly modified and used as wire stripping pointed nose pliers. The method is to use an electric drill to drill two 0.8mm and 1.0mm slots in the front of the cutting edge of the needle nose pliers, and then slightly expand them with 1.2mm and 1.4mm drill bits respectively. Note: do not expand through, so that these two slots have a thin cutting edge. In this way, a pointed nose pliers that can cut and strip threads has been changed!
Wire stripping pliers are one of the commonly used tools for internal line electricians, motor repair, and instrumentation electricians. It is suitable for peeling plastic, rubber insulated wires, and cable cores. The usage method is: place the wire head to be peeled into the cutting edge of the pliers, pinch the two pliers handles with your hand, and then release them, and the insulation skin will detach from the core wire.
