Open socket spanner for narrow and small space

Abstract

The invention relates to a spanner, and belongs to the technical field of hardware tools. The spanner comprises a main spanner body, an auxiliary spanner body and a connecting shaft. The main spannerbody comprises a main spanner head, a main sleeve and a main spanner handle and is clamped with a bolt or nut to be demounted and mounted for demounting and mounting work, and the main spanner body isused as a bent handle for increasing the force arm when the auxiliary spanner body works. According to the spanner, a pipeline can penetrate through the spanner, and a nut on the pipeline can be mounted and demounted. The spanner can also be used for demounting and mounting work of a nut or bolt in the narrow and small space or a deep concave place. The technical problem that a sleeve hole of anexisting sleeve spanner is sealed, the pipeline cannot penetrate through the spanner, and the activity of the existing open spanner in the narrow and small space is limited is solved. If the main spanner body works, the auxiliary spanner body serves as the bent handle. If the auxiliary spanner body works, the main spanner body serves as the bent handle. The use range of the spanner is widened, andoperation is convenient and efficient.

Description

technical field [0001] The invention belongs to the technical field of hardware tools, in particular to an open socket wrench used in a narrow space. Background technique [0002] A wrench is a commonly used installation and removal tool. Turning fasteners such as bolts, screws, and nuts using the principle of leverage, but often limited in tight spaces. For example, when installing or disassembling kitchen faucets, bathroom faucets and toilet water fittings, when replacing the corresponding hoses, due to the narrow operating space, the operation of ordinary wrenches is limited and inconvenient to operate. [0003] In order to screw the bolts or nuts with very narrow space or deep recesses, socket wrenches have appeared. A socket wrench generally consists of multiple sockets of different specifications and is equipped with various accessories such as handles and extension rods. The sleeve is generally a cylindrical structure with hexagonal or twelve-pointed holes, but the...

AI Technical Summary

Problems solved by technology

[0004] The existing socket wrench can avoid the limitation of narrow space when installing kitchen faucets, bathroom faucets and toilet water parts, and is indeed effective; but when replacing the hoses of kitchen faucets, bathroom faucets and toilet water parts, due to The socket of the socket wrench is closed and cannot pass through the connected hose, so it is useless

The opening of ordinary wrench or live end wrench can pass through, but limited by the narrow space, it is inconvenient to operate

[0005] In order to solve the problem that the existing socket wrench is closed and cannot pass through the pipeline, and the existing open-end wrench is limited in movement in a narrow space, the present invention proposes an open-end socket wrench for a narrow space
