    Guide: Wrench is one of the common hardware tools in our family. According to its power, wrenches can be divided into electric wrenches and manual wrenches. At present, manual wrenches are still used more frequently in our family, although they are tools that can be seen everywhere in our lives. , But its classification and use may not be understood by most people.

First of all, I’m talking about one of the most common and primitive open-end wrenches; open-end wrenches are also called dead-end wrenches. They are divided into single-head and double-headed. The size of the opening can be adjusted according to different nut sizes, and some According to the existing standard size, a set that cannot be adjusted is made, including square, hexagon, and dodecagonal. Among them, the dodecagonal wrench is also called the plum blossom wrench. It is most frequently used by the public. Its advantage is that it can Used in a small space, the rotation range is small, and the application range is wide. It is particularly convenient to disassemble and assemble the hexagonal nuts or bolts in the slightly recessed area.

Another common type of wrench is a socket wrench, which is composed of a set of plum tubes of different sizes, in which a bow-shaped handle is used for continuous rotation, which can greatly improve work efficiency and save energy. This set of wrenches is also suitable for working in small spaces. This is the ratchet wrench. Its rotation angle is small, so it is suitable for tightening or unscrewing screws and nuts.

There is also a kind of disassembly and assembly commonly used in electromechanics, which is an Allen wrench. This kind of wrench has a long elastic rod, one end of which is equipped with a handle, and the other end is equipped with a square or hexagonal head. A replaceable sleeve is fitted on the square or hexagonal head to be clamped. There is also a long pointer on the top. The scale plate is fixed on the handle base, and the scale value per division is 1 Newton (or kg/m). So when a certain value of tightening force is required in the operation, or several nuts (or screws) need the same tightening force, use the help of this wrench. Colleagues are also used for the disassembly and assembly of large nuts, for example, common electricians use it to load and unload steel structures such as iron towers.

There are many other common wrenches, such as adjustable wrenches, also called adjustable wrenches, which are tools for tightening or loosening angled screws or nuts. When using, hold the handle with your right hand. The farther back the hand is, the more effortless it is to pull. When pulling a small nut, because you need to constantly rotate the worm wheel to adjust the size of the wrench, you should hold your hand close to the lip of the idler, and use your thumb to adjust the worm gear to fit the size of the nut.

There are too many types of wrenches, so the examples are not explained one by one. It is best to consider the scope of application when choosing a wrench, so that you can more appropriately choose the right type and model, which will not only save you effort, but also improve work efficiency. . At the end, I would like to remind you that people often use wrenches as hammers in life. This will cause great damage to the tools. Improper operation will also make the wrench version. Therefore, it is recommended to choose the right tool according to different tasks. work method.
