Problems solved by technology
[0004] The technical problem to be solved by the present invention is: although the adjustable wrench can be applied to many bolt sizes, it needs to be adjusted frequently, the rigidity is naturally insufficient, and long-term use will cause wear and tear , and the manufacturing cost and material cost are higher; while the dead wrench is slightly higher in rigidity than the live wrench, but the available size is limited, and many of them only have one size available, and there are at most two sizes, that is, a wrench is set on each side of the wrench head so that the sides can have different sizes, but still not enough

A multi-sized integrated wrench is characterized by being provided with a plurality of single wrenches, wherein the single wrenches are integrated and made of hard metal, each single wrench is provided with a nut opening with a different size, each nut opening is of a closed type, and all the single wrenches are connected one by one. The multi-sized integrated wrench is applicable to different nuts with different sizes, also can provide higher strength and has the advantages of high strength and multiple sizes; and moreover, the multi-sized integrated wrench is convenient to carry and easy to use.
Description
technical field : [0001] The invention relates to a wrench, in particular to a multi-size integrated wrench, which belongs to the technical field of hardware tools. Background technique : [0002] A wrench is a hand tool that uses the principle of leverage to turn bolts, screws, nuts, and other openings or sockets that are threaded to hold bolts or nuts. The wrench is usually formed with a clamping handle at one or both ends of the handle to apply an external force to the handle to twist the bolt or nut to hold the opening or sleeve of the bolt or nut. When in use, an external force is applied to the shank in the direction of thread rotation, so that the bolt or nut can be twisted. Wrenches are basically divided into two types, namely dead wrench and adjustable wrench. The former refers to a wrench that has been fixed and marked with specifications, and the latter is an adjustable wrench that can adjust the jaw size. [0003] Wrenches can also be divided into many types,...
