1.Screwdriver
A tool used to twist a screw to force it into place, usually with a thin wedge-shaped head that can be inserted into the slot or notch of the screw head-also known as a “screwdriver.”
2.wrench
A hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other threaded fasteners to hold the openings or sets of holes of bolts or nuts.Wrenches are usually made with a clamp at one or both ends of the shank to apply an external force to the shank to twist the bolt or nut to hold the opening or socket of the bolt or nut.When used, an external force is applied to the shank along the direction of rotation of the thread to twist the bolt or nut.
3.hammer
It is a tool that beats an object to move or deform it.It is most commonly used to knock nails, correct or knock objects apart.Hammers come in various forms, the common form is a handle and a top.One side of the top is flat for percussion, and the other side is a hammer.The shape of the hammer head can be like a sheep's horn or a wedge-shaped shape, and its function is to pull out the nail.There is also a round-headed hammer head.
4.Test pen
Also known as the electric measuring pen, referred to as the “electric pen”.It is an electrician's tool used to test whether there is electricity in the wire.There is a neon bubble in the pen body. If the neon bubble emits light during the test, it means that the wire has electricity, or it is the firewire of the passage.The nib, end, and tip of the test pen are made of metal materials, and the pen holder is made of insulating materials.When using the test pen, you must touch the metal part of the end of the test pen with your hand. Otherwise, because the charged body, the test pen, the human body and the earth do not form a circuit, the neon bubbles in the test pen will not emit light, causing a misjudgment that the charged body is not charged.
