The wrench is mainly used to tighten or release bolts and nuts with hexagonal or other shape sections. The principle is to increase the torque through lever, and the user can achieve large tightening or loose effects with smaller force.There are many types of wrenches on the market. Common open wages, activity wrenches, sleeve wrenches, torque wrenches, etc. have different applicable occasions and functional characteristics.

How does the wrench work? This involves a basic concept in physics -the principle of leverage.Simply put, when you tighten or release a bolt with a wrench, the force you applied on the wound removal handle will be amplified by lever, resulting in sufficient torque to rotate the bolt.The key here lies in the length of the force arm, the distance from the point of force to the point of force.The longer the force arm, the greater the torque generated by the same size, so it can be easier to complete the work.
Application of wrench in different scenarios:
In the field of mechanical maintenance, wrenches are almost indispensable tools.Whether it is automobile maintenance, aircraft maintenance, or ship maintenance, it is inseparable from its help.For example, when replacing the car tire, we need to use a wrench to loosen and tighten the hub screw;
When repairing household appliances, it also needs to use it to remove the screw fixing parts on the shell.
In addition, the wrench is widely used in the fields of construction construction, home decoration and other fields.It can be said that as long as it involves a thread connection, a wrench may be used.
In practical applications, the choice and use of wrenches also need to take into account the working environment and specific operating needs.For example, in automotive maintenance, because the operation space is usually more limited, the sleeve wrench and torque wrench become a better choice.In the daily maintenance of the family, the opening wrench and activity wrench are more popular due to its simplicity.For novices, the characteristics and correct use of various wins are the key to improving maintenance efficiency and quality.
In addition to choosing the right wrench, it is also important to understand some basic maintenance principles.For example, when tightening the bolt of the key parts, the principle of cross -tightening should be followed to ensure the balanced force of the connection and prevent deformation.At the same time, regular inspections and maintenance wrenches are equally important. For example, keep the wrench cleaning and regular lubrication of activity components, etc., it can effectively extend the service life of the tool.
In modern industrial society, whether it is automotive maintenance or aircraft manufacturing, all kinds of bolts and screw connections are inseparable, so the use of wrenches is very common.However, with the advancement of technology, peoples requirements for wrenches are also getting higher and higher: not only requires the wrench to quickly and accurately complete the tightening or spin pine work, but also hopes that the wrench can be more user -friendly to reduce the labor intensity of the operator.
To this end, many engineers began to try to improve the wrench.For example, they add torque indicators to wrench, so that the operator can intuitively understand the torque size applied; as well as, they add rubber cover on the handle of the wrench to increase the comfort of the grip.In addition, some new variable angle wits can also work in a limited space to improve work efficiency.
