Abstract

The invention discloses a pen type auxiliary tool in a resistance strain gauge pasting process. A pen point is connected with a pen body through threads, a pen tail is connected with the pen body through threads, an air bag is arranged in a cavity in the pen body and the pen tail, the front end of the air bag is pressed on a step flange on the inner wall of the pen body through an air bag front end pressing ring, a through notch is formed in the middle of the pen body,an air bag compression button is arranged in the circumferential direction of the air bag, and the air bag compression button is embedded in and penetrates out of the notch. According to the invention, the problems of difficulty in controlling the sticking direction of a strain gauge and sliding of the strain gauge during pressing in the traditional strain gauge sticking process in engineering test are effectively solved, and the pen type auxiliary tool is simple in structure, common in material, low in cost, easy to realize, novel and unique, and solves the problems in the traditional strain gauge sticking process in engineering test conveniently and quickly, and the pasting quality of the strain gauge is ensured.

Description

technical field [0001] The invention relates to a written examination auxiliary tool in the field of electronics and communication engineering, in particular to a pen-type auxiliary tool in the pasting process of resistance strain gauges. Background technique [0002] Resistance strain gauges can convert micro-strains of engineering components into resistance changes, and are generally composed of sensitive grids, leads, adhesives, substrates and cover layers, and are widely used in the field of engineering testing. At present, in the traditional strain gauge pasting process, the left hand is usually used to pinch the lead wire of the strain gauge, the right hand is used to apply glue, and then the resistance strain gauge is pasted to the surface of the component, and the right hand is used to cover the strain gauge with a plastic film, and the thumb is pressed to make the strain gauge in place. The surface of the component is pasted. In this strain gauge pasting process, t...
