[0002] A wrench is a commonly used installation and disassembly tool, a hand tool that uses the principle of leverage to turn bolts, screws, nuts and other threaded fasteners that hold the openings or holes of bolts or nuts. Wrenches are usually made of structural steel made of carbon or alloy materials. Wrenches usually have openings or holes for clamping bolts or nuts at one or both ends of the handle. When in use, an external force is applied to the handle along the direction of thread rotation to turn the bolt or nut. However, the existing wrenches have a single structure, and the handle part remains unchanged during use, which makes the screwing and turning process consuming a lot of effort, and it cannot be used continuously and conveniently according to the different specifications of the nuts to be screwed during use. It is necessary to constantly replace wrenches of different sizes, which reduces efficiency. Therefore, an adjustable wrench is urgently needed to solve the above problems. Utility Model Content
