Introduction: One of the hardware tools commonly used in our homes is wrenches. According to its power, it can be divided into electric wrenches and manual wrenches. At present, we use hand-held wrenches in our homes, although it is a tool that can be seen everywhere in our lives. , but its classification and use may not be understood by most people.

The first and most common is the open-end wrench. The open-end wrench is also called the open-end wrench. It is divided into single head and double head. The size of the opening can be adjusted according to different nut sizes, and some will According to the existing standard size, it can be made into a set that can not be adjusted, including square, hexagonal, and dodecagonal. Among them, the dowel-shaped wrench, also called the plum wrench, is most commonly used by the public at the point. Its advantage is that Used in a smaller space, the rotation is smaller and the application is wider. It is particularly convenient to remove the hex nuts or bolts that are located in the slightly recessed area.

Another common wrench is the socket wrench, which is composed of a set of different size plum blossom cylinders, in which the continuous rotation with the arcuate handle can greatly increase the work efficiency and save the physical strength. This set of wrenches also has a small space for work. This is a ratchet wrench. It has a small rotation angle, so it is suitable for tightening or unscrewing screws and nuts.

There is also a type of disassembly used in electromechanics. He is an Allen wrench. This type of wrench has a long spring rod with a handle at one end and a square or hexagonal head at the other end. A replaceable sleeve fits over the square head or hex head. There is also a long pointer on the top. The scale plate is fixed on the handle and the scale value is 1 Newton (or kilograms per meter). So when the job requires a certain amount of tightening force, or when several nuts (or screws) require the same tightening force, use this wrench to help. Colleagues He was also used to dismantle large nuts, such as the common steel structure used by electricians to load and unload steel towers.

There are many other common wrenches, such as a loose spanner and a live spanner, which are tools that tighten or loosen an angled screw or nut. In use, the right hand holds the handle. The more backward the hand is, the easier it is to pull it. When the small nut is pulled, because the worm wheel needs to be continuously rotated to adjust the size of the wrench, the hand should be held close to the lip, and the worm wheel is modulated with the thumb to adapt to the size of the nut.

If there are too many kinds of wrenches, the examples will not be elaborated one by one. It is better to consider the scope of application when choosing the wrench. This will make it possible to choose the right type and model more appropriately. This will not only save you labor, but also improve work efficiency. . In the end, we must also remind people that people often use wrenches as hammers in daily life. This will cause great damage to the tools. Improper operation will also make the model of the wrench type. Therefore, it is recommended that the right tool be selected according to different tasks. work method.
