Screws are the main fasteners in mechanical equipment. Open-end wrenches are an important tool for processing, production and maintenance in the mechanical industry. This project is a revolution in traditional wrench tools, and it has the following advantages. 1. It works fast and works three to four times faster than conventional wrenches, faster than a quick wrench. 2. An open-end wrench can be used for 2 to 6 screws, while a double-headed wrench can only be used with 2 types of screws. An open-end wrench is equivalent to 2-3 wrenches, which is equivalent to an adjustable wrench but can work quickly without adjusting the opening. 3. Long service life, bad, and the front quick wrench is easy to break. 4. The manufacturing process is simple and the cost is lower than the wrench. 5. Light weight, easy to carry, and labor-saving.
