Collection of hand tools, a collection of hand tool types and information about their use
1. Hand Tools
A tool used to drive a screw into place, usually with a thin wedge-shaped head that fits into a slot or notch in the head of the screw, is also called a "screwdriver".
Hand tools used to drive bolts, screws, nuts, and other open or flared fasteners with threads that hold the bolts or nuts in place in a lever-like manner. A wrench typically has a clamping handle at one or both ends of the handle for applying an external force to the handle to tighten a bolt or nut to hold the hole or sleeve of the bolt or nut. In use, an external force is applied to the shank in the direction of rotation of the thread so that the bolt or nut can be driven.
A tool for striking an object to move or deform it. It is most often used for hammering nails, straightening or knocking out objects. Hammers come in many shapes, the most common being the handle and pommel. One side of the top is flat for striking and the other side is a hammer head. The shape of the hammer head can be horn-shaped or wedge-shaped, and its function is to pull out the nail.
It is also called a test pen, or "electric pen" for short. This is an electrician's tool used to test for the presence of electricity in a wire. There is a neon light bulb in the pen body, if the neon light is on during the test, it means there is electricity in the wire, or it is a live track wire. The nib and tail of the test pen are made of metal materials, and the pen holder is made of insulating materials. When using the test pen, be sure to touch the metal part at the end of the test pen with your hands. Otherwise, because the electrified body, the test pen, the human body and the ground do not form a circuit, the neon light in the test pen will not emit light, causing the misconception that the charged the body does not live.
A measuring tape is a common measuring tool in everyday life. What you often see is a steel tape measure, which is commonly used in construction and decoration, and is also one of the must-have tools for families.

The blade has a concave curved knife edge, and the end of the curved edge of the knife forms a sharp edge. On the handle there is a safety button that prevents the blade from bouncing. The electrician's knife blade has many functions. Using it, only one electrician's knife can perform various wire-connecting operations without the use of other tools. It has the beneficial effects of simple structure, convenient use, and diversified functions.
Including hand saws (household, woodworking), miter saws (cutting branches), folding saws (cutting branches), hand bow saws, edge saws (woodworking), rip saws (woodworking), miter saws (carpentry) . level: The level has a bubble level that can be used for inspection, measurement and debugging to see if the equipment is installed horizontally.
There are many small teeth and bars on the surface, hand tools for filing workpieces. It is used for microprocessing of metal, wood, leather and other surfaces.
This is a hand tool for clamping, fixing workpieces or twisting, bending and cutting wire. The shape of the pliers is V-shaped and usually consists of three parts: the handle, the jaws of the pliers, and the mouth of the pliers.
Wire cutters are a kind of clamp and cutting tool, consisting of a pliers head and a pliers handle. The pliers head includes a jaw, a tooth mouth, a knife blade, and a guillotine. Functions of each part of the pliers: ① The notched mouth can be used to fasten or loosen the nut; ② knife blade can be used to cut the rubber or plastic insulation layer of the flexible wire, and can also be used to cut the wire and iron wire; ③ Guillotine can be used to cut hard metal wire such as wire and steel wire; ④ The insulating plastic tube of the pliers can withstand over 500V, and it can cut wires with electricity.
Needle nose pliers
Also known as a repair plier, it is mainly used for cutting solid and stranded wires with thinner wire diameters, as well as bending the connections of single-core needle nose pliers, stripping plastic insulation layers, etc. It is also an electrician (especially one of commonly used tools for interior electricians). It consists of a pointed head, a knife blade and a pliers handle. The handle of the electrician's needle-nose pliers is covered with an insulating sleeve for a rated voltage of 500V. The pliers have a sharp head, so they are used in narrow spaces. Working method using needle nose pliers to bend the wire connector: first bend the end of the wire to the left, and then bend it to the right in a clockwise direction next to the screw.
The wire stripper is one of the most commonly used tools for electricians, motor and instrumentation repairmen. Its appearance is shown in the figure below. It consists of a knife blade, a crimp neck and a pliers handle. The handle of the wire stripper is covered with an insulating sleeve with a rated operating voltage of 500V. The wire stripper is suitable for stripping plastic and rubber insulated wires and cable strands. Use method: put the end of the wire to be stripped into the cutting edge of the head of the pliers, clamp the two handles of the pliers with your hands, and then loosen, the insulation will be separated from the core of the wire.
It consists of three main parts: measuring head, measuring circuit and switch, which are used to measure current and voltage.
