Universal wrench

Abstract

A universal wrench comprises a wrench head, a handle, upper antiskid teeth, lower antiskid teeth and a torque spring. The upper end part of the handle is provided with a rectangular groove. The upperantiskid teeth and the wrench head are formed integrally. The lower antiskid teeth and the handle are formed integrally. The upper antiskid teeth are arranged in a V-shaped track. The lower antiskid teeth are arranged at the front end of the handle and are arranged in an arc-shaped track. A rivet penetrates through holes in the two sides of the rectangular groove sequentially. The lower end of thewrench head is embedded into a connecting through hole in the rectangular groove to connect the handle and the wrench head oppositely and fixedly, and a whole wrench is formed. The universal wrench is characterized in that the lower end of the wrench head is provided with a spring hole; a screw is fixed in a screw hole machined in a plate on one side of the rectangular groove of the handle; the bent end of the torque spring is inserted into the spring hole; and the sleeved connection end of the torque spring is fixedly connected to the thread section, located in the rectangular groove, of thescrew in a sleeving mode. The universal wrench can act on multiple sizes of bolt and nut assemblies and tubular fasteners simultaneously, cost is low, the structure is simple, operation is easy, multiple purposes are achieved through the one universal wrench, and the carrying burden of a worker, especially an outdoor worker, is relieved.

Description

technical field [0001] The invention relates to the field of machining, in particular to a universal wrench. Background technique [0002] At present, universal wrenches are widely used in various fields, mainly used for the disassembly and installation of parts, usually composed of wrench movable parts, handles and other structures; at the work site, because many bolts are non-standard parts, the staff disassemble or tighten the bolts It is often necessary to use wrenches with different functional sizes. It is inconvenient to carry multiple sets of tools for outdoor work, and searching for suitable tools among multiple sets of similar tools will prolong the working time; The edges and corners of the wrench have been worn and rounded, and a dull wrench cannot be clamped and fixed. The pipe wrench is bulky and inconvenient to carry, and at the same time, it cannot work in a small space. Therefore, an easy-to-carry universal wrench with multiple clamping ranges is urgently nee...

Problems solved by technology

[0002]At present, the universal wrench is widely used in various fields, mainly used for the disassembly and installation of parts, usually composed of wrench movable part, handle and other structures; On site, because many bolts are non-standard parts, workers often need wrenches of different sizes when disassembling or tightening bolts. It is inconvenient to carry multiple sets of tools for outdoor work, and searching for suitable tools among multiple sets of similar tools will prolong the working time; secondly, Due to corrosion, wear and other reasons of long-term use of the bolt and nut assembly, the edges and corners of the parts have been worn and rounded, and the dull wrench cannot be clamped and fixed, and the pipe wrench is bulky and inconvenient to carry, and at the same time, it cannot go deep into the narrow space. Therefore, there is an urgent need for a Portable universal wrench with multiple clamping ranges
