Screws are the main fasteners in mechanical equipment. Open-end wrenches are important tools for processing, production and maintenance in the machinery industry. This project is a revolution of traditional wrench tools. It has the following advantages.
1. Works fast, working three to four times faster than traditional wrenches and faster than a quick wrench.
2. An open-end wrench can be used for 2-6 kinds of screws, while a double-ended wrench can only be used for 2 kinds of screws. An open-end wrench is equivalent to 2-3 fixed wrenches, equivalent to an adjustable wrench but can work quickly without adjusting the opening.
3. It has a long service life and cannot be broken, and the front quick wrench is easy to break.
4. The manufacturing process is simple, and its cost is lower than that of a dumb wrench.
5. Light weight, easy to carry, labor-saving work.
