Problems solved by technology

However, a wrench with a long handle is inconvenient or even unusable when used in some small spaces
For example: the disassembly and installation of the hose joint nut of the bathroom faucet in the family and hotel. Since the washbasin and toilet are mostly arranged against the wall or corner, the use of wrench space is limited during maintenance.

Abstract

The invention provides a using method for an adjustable open wrench. The used wrench is mainly composed of a main body and a movable body. The using method comprises the following steps that according to the dimensions of nuts, the specifications of the main body and the movable body are chosen, and matching installation is conducted; convex clamping plates of the movable body and clamping ports of the main body are utilized for tightly clamping the nuts, and handles are held by hands for loosening or screwing up the nuts; and finally the main body and the movable body of the wrench are reversely detached and put into a specially-designed tool packet for later use. The using method for the adjustable open wrench has the beneficial effects that the outline is small, exquisite and attractive, and the using method is free of clumsy handles. For some domestic appliances or other devices which are installed and inconvenient to detach, the wrench is convenient to use and carry and capable of saving time and labor.

Description

technical field [0001] The invention relates to a method for using a tool for installation and use, in particular to a method for using an adjustable small open-end wrench used in a narrow space. Background technique [0002] Due to the development of science and technology and industry and the improvement of living standards, more and more people come into contact with screws and nuts of various sizes in their daily utensils. Therefore, in the assembly and adjustment of screw rods and nuts in household appliances, especially in the working process of maintenance, nuts of different sizes need to be adjusted, and the basic tool needed is exactly a wrench. There are basically two types of wrenches, dead wrenches and open-end wrenches. The opening width of the adjustable wrench can be adjusted within a certain size range, and bolts or nuts of different specifications can be screwed. The structural features of the wrench are: a fixed jaw with a fine-toothed flat jaw, and a mov...
