Hardware tools are widely used in everyday life, such as repairing lamps and tying things. In everyday life, a breakdown of some little thing is inevitable, but help of a repairman is not worth it, you can solve it yourself. But some people don't know how to use some hardware tools like wrenches, pliers, electrician's knife, especially for girls. But in independent life, use of this hardware to repair things is inevitable. For a more convenient life, let's learn some methods of using Xi'an Stanley hardware.
1. How to use a wrench
Open-end wrenches (also called blunt wrenches) are often used in families. It has two kinds of single and double heads, its hole is suitable for size of screw head and nut, and it is a set according to standard size.
Built-in wrenches come in square, hex, and dodecagonal (commonly referred to as plum wrenches). Among them, plum wrench is widely used by rural electricians. As long as it is rotated 30°, direction of wrench can be changed, so it is more convenient to work in narrow places.
The trade wrench consists of a set of plum blossom tubes of different sizes. When used, arc-shaped handle is used for continuous rotation, which ensures high working efficiency. When size of screw or nut is large or working position of wrench is very narrow, a ratchet wrench can be used. This wrench has a small angle of rotation and can tighten and loosen screws or nuts. Turn knob clockwise while tightening.
The square sleeve is equipped with a spacer. When handle is pulled back in opposite direction, spacer slides out of ratchet tooth ramp so that screw or nut does not rotate in reverse direction. If you need to loosen a screw or nut, simply reverse ratchet wrench and turn it counterclockwise.
Internal hex wrench is used to install and remove internal hex screws. It is often used to disassemble and assemble some mechanical and electrical products.
A hex wrench is used to install and remove large hex screws or nuts, and can be used by third-party electricians to install and remove steel-framed structures such as iron towers.
A drain wrench, commonly known as an eye wrench, is used to remove hex nuts or bolts. It is especially convenient to disassemble and assemble hex nuts or bolts located in slightly recessed places.
An adjustable wrench, also known as an adjustable wrench, is a tool for tightening or loosening angle screws or nuts. Three types are commonly used by electricians: 200, 250 and 300mm and should be selected according to size of nut when used.
When using, hold pen with your right hand. The farther back arm is retracted, less effort is required to pull it. When turning small nut, it is necessary to continuously turn worm gear to adjust key size, so hand should be kept close to lug of key, and worm gear should be adjusted with thumb according to key size. nut size. When wrench of adjustable wrench is clamping nut, wrench tab is on top and adjustable wrench tab is on bottom. The wrench cannot be used in reverse direction. When tightening a rusty nut, you can put a few drops of kerosene or machine oil on nut.oil so that it can be easily screwed on. When it cannot be screwed, it is absolutely impossible to use steel pipe to cover handle of adjustable wrench to increase torque, because lug of adjustable wrench can be easily damaged. Do not use an adjustable wrench as a hammer.
2. Method of using pliers
When using cable wrap pliers, teeth of pliers pinch wire and wrap it around in a clockwise direction. Pliers, commonly known as needle nose pliers, are also one of frequently used tools for electricians (especially for interior electricians). It is mainly used for cutting small diameter solid and stranded wires, bending solid wire connections, stripping plastic insulation layers, etc.
Working method for bending a wire connection with needle nose pliers: first bend end of wire to left, and then bend it to right clockwise next to screw.
Slightly modified needle nose pliers can be used as wire strippers. The method is as follows: using an electric drill, drill two slotted holes of 0.8 and 1.0 mm in front of cutting edge of needle nose pliers, and then use a 1.2 and 1.4 mm drill bit to expand a little (note: do not expand through!), so that each of two slots has a thin edge. So needle nose pliers that can both cut and strip wires have been replaced!
Wire strippers are one of tools commonly used by interior electricians, engine repairers and instrumentation electricians. It is suitable for stripping plastic and rubber insulated wires and cable strands. Use method: put end of wire to be stripped into cutting edge of head of pliers, clamp two handles of pliers with your hands, and then loosen, insulation will be separated from core of wire.
Never use pliers instead of a hammer. Do not use pliers to cut two live wires as this will cause a short circuit.
3. How to use an electrician's knife
The electrician's knife is a widely used cutting tool. A typical electrician's knife consists of a blade, a blade, a handle, and a knife holder. When not in use, blade retracts into handle. When cutting insulating layer of a wire with an electrician's knife, knife can be tilted slightly, and rounded corner of blade can be used to hold wire strand. Do not cut insulating layer with blade perpendicular to wire, as strand of wire can be easily cut. The insulation on wires must be stripped before splicing wires. When cutting and stripping with an electrician's knife, edge of knife should not touch core of wire. The commonly used mining methods are staged and sloping stripping.
The above are methods for using some simple hardware tools. In fact, these tools are very easy to use and you can learn them once you get hang of it. I hope above usage methods will help you and make your life more comfortable.
