Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the application clearer, the application will be further described in detail below in conjunction with the accompanying drawings.

[0034] In order to facilitate the understanding of the wrench provided in the embodiment of the present application, the specific application scenarios are firstly explained below. The wrench provided in the embodiment of the present application can be used, but not limited to, in the equipment assembly process in the assembly workshop, and is specifically used to realize the component connection process Fasteners such as screws or bolts are tightened in place. In some existing technical solutions, the wrench is only used to fasten the fasteners during the component connection process, and then the fastened fasteners are marked by an additional step of marking. However, the process of drawing the logo is easy to be missed, resulting in the missing of a certain fastener tight...

Abstract

The invention provides a wrench, and relates to the technical field of machining jigs. The wrench comprises a wrench main body and a spraying device fixed on the wrench main body; the wrench main bodycomprises an inner rod and an outer barrel, and the outer barrel is rotationally connected with the inner rod; the spraying device comprises a container, a spraying mechanism and a nozzle, wherein the spraying mechanism is fixedly connected with the outer barrel; and when the outer barrel rotates by a set angle relative to the inner rod, the spraying device can be triggered to spray liquid. According to the embodiment, by adopting the wrench, fastening and marking on a fastener can be completed at a time, so that the situation that fastening on the fastener is omitted is avoided, the assemblyefficiency can be effectively improved, and potential safety hazards are reduced.

Description

technical field [0001] The present application relates to the technical field of processing jigs, in particular to a wrench. Background technique [0002] In the assembly process of industrial equipment, the reliability of the connection between various parts is really important. When connecting parts, fasteners are usually required. When the fasteners are fastened, they need to be fastened according to the specification or required torque, otherwise, some fasteners may be missed, or the fasteners may become loose and fail due to insufficient tightening torque, which will cause Lead to greater safety risks and quality risks. [0003] At present, when tightening fasteners, torque wrenches are mostly used to tighten the fasteners, and manual marking is used to avoid missing the tightening of certain fasteners. However, in the process of tightening the above-mentioned fasteners, two operations are required to complete, the assembly efficiency is low, and the process of marki...
