Common Hand Tools in Our Daily life

The classification of several hand tools commonly used in daily life and their functions are introduced:

Wrench:

All kinds of wrenches, including adjustable wrenches, Allen wrenches, torque wrenches, socket wrenches, special wrenches, etc.

What is an Adjustable Wrench?

Adjustable wrenches are mainly tools for tightening hexagonal, square screws, and various nuts. Made of tool steel, alloy steel, or malleable cast iron. Generally divided into general, special, and special three categories. When using, the adjustable wrench should be selected according to the shape, specification, and working conditions of the screw and nut.

The adjustable wrench is composed of a wrench body, a fixed jaw, a movable jaw, and a worm. The afterburner direction of various wrenches is fixed, and the mouth of the reverse afterburner will open outward, so when applying force, it is necessary to confirm the afterburner direction of the wrench.

What is a Socket Wrench?

The socket is short for a socket wrench. A special tool for tightening or loosening screws. It is composed of several inner hexagonal sockets and one or several handles of the upper socket. The inner hexagonal sockets of the socket are arranged in sequence according to the type of bolts, which can be selected as required. It is used for tightening or loosening bolts and nuts with large torque or special shapes on the head.

What is an Allen Key?

The hexagon socket wrench is an L-shaped hexagon rod wrench, which is specially used for turning the socket head cap screws. Inch and metric are two types, that need to convert the size. For tightening or loosening standard hexagon socket head cap screws.

What is a Percussion Wrench?

The percussion wrench belongs to a special type of wrench and is a necessary tool in equipment installation, equipment maintenance, and repair work. It is mainly used to fasten and disassemble bolts or nuts with large torque. The percussion wrench has the characteristics of strong resistance to impact, not easy to break, firm and durable, and easy to use and store. Select the corresponding percussion wrench according to the size of the bolt, place the wrench flat on the bolt or nut, and then use a hammer to strike the other end of the wrench to make the wrench rotate to achieve the purpose of loosening the bolt or nut. You can also use a steel pipe to lengthen the force. Arm or tap, hammer, and easily tighten or remove large nuts.

Screwdrivers:

Flat-blade screwdriver, Phillips screwdriver.

What is a Screwdriver?

Screwdrivers are used to rotate slotted screws, wood screws, and self-tapping screws. It has a variety of specifications. The large and small screwdrivers are expressed by the length of the knife body other than the handle. The commonly used ones are 100mm, 150mm, 200mm, 300mm, and 400mm. Choose different screwdrivers according to the size of the screw.

Cross-shaped screwdrivers are used to rotate cross-recessed screws, wood screws, and self-tapping screws. When using a cross-shaped screwdriver, care should be taken to make the end of the screw rod fit with the screw groove. Otherwise, the cross groove of the screw may be easily damaged.

Pliers:

Needle nose pliers, circlip pliers, etc.

What are Wire Cutters (Hand pliers)?

The wire cutter is a kind of hardware tool, which is a special tool for clamping the workpiece or cutting the workpiece. The jaw is not fixed. The other is the electrician's hand pliers, which are mainly used for cutting wires. The wire cutter is composed of a clamp head and a clamp handle. The electrician's wire pliers handle is covered with an insulating rubber sleeve, which has a certain pressure resistance to prevent electric shock.

What are Needle Nose Pliers?

Trimmers are one of the tools commonly used by electricians. It is mainly used for cutting single-strand and multi-strand wires with thin wire diameter, bending the joints of single-strand wires, stripping plastic insulation layers, clamping small parts, etc. It can be operated in a narrow working space. Those without a cutting edge can only work by pinching, and those with a cutting edge can cut small parts. It is often used as a tool for assembly and repair operations such as instruments and telecommunication equipment.

What are External Circlip Pliers (Straight and elbow)?

The pliers can be inserted into the two holes of the circlip, and then the inner or outer diameter can be enlarged or reduced. Use a steady force to prevent it from falling off or breaking. Use a gloved hand to protect the circlip after it breaks, and wear goggles.

What are Internal Circlip Pliers (Straight and elbow)?

The pliers can be inserted into the two holes of the circlip. Then expand or reduce the inner diameter or outer diameter. Use a steady force to prevent it from falling off or breaking. Use a gloved hand to protect the circlip after it breaks, and wear goggles.

What is a Pipe Wrench?

With the friction force and the force generated by the clamping on both sides, it can fix water pipes and steel pipes, or disassemble metal pipes and other cylindrical parts. It is a common tool for pipeline installation and repair work.

Knocking class:

Hand hammer, chisel, etc.

What is a Hand Hammer?

A hand hammer consists of a hammerhead and a handle. The weight of the hammerhead is 0.25 kg, 0.5 kg, 0.75 kg, 1 kg, etc. The Hammerhead shape has a round head and a square head. The handle is made of hard miscellaneous wood, and the length is generally 320~350 mm. The hand hammer is mainly used to strike the workpiece to deform, displace and vibrate the workpiece, and can be used for tool correction and shaping.

What is a Chisel?

Tools for machining materials by chiseling, engraving, turning, and cutting. Has a short metal rod with a sharp edge at one end? The method of using a hammer to strike a chisel to cut a metal workpiece is called chisel cutting. It is mainly used to remove flanges, burrs, split materials, chisel planes, and oil grooves on the blank, and is often used in situations that are not convenient for machining. The chisels commonly used by fitters include flat chisels, sharp chisels, and oil groove chisels.

What is the Textile Industry?
The upstream of the textile industry chain is the petrochemical raw material. After being manufactured into nylon fiber, polyester fiber, rayon fiber, carbon fiber and other human fiber products, it is spun into yarn, then woven into cloth, and then bleached, dyed, printed, Dyeing and finishing procedures such as coating, finishing, tailoring and sewing into garment products or other related textile products. The textile manufacturing process can be divided into four stages: fiber, textile, dyeing and finishing, ready-to-wear/home textiles, among which textiles can be further divided into two steps: spinning and weaving: spinning is the transformation of roving into spun yarn. After being sent to the factory, the yarn is inserted into the operation axis of the textile machine table, and the textile machine table pulls the yarn upward and sends it to the textile machine; the next step is the weaving step, at this stage, the shuttle is used in the textile machine. It shuttles back and forth continuously, and finally weaves it into a piece of cloth. After finishing the cloth fabric (including cotton, wool, synthetic fiber, etc.) into a box, it can be sent to downstream manufacturers for post-processing to form a textile industry chain.
