Digital wrench backlight module structure

The invention relates to a digital wrench backlight module structure, which is a digital torque wrench with a backlight display effect. The backlight display effect can improve the warning range of the light source and reduce the production cost.

Press, the wrench tool uses the principle of lever to pull the screw-solid workpiece to achieve the effect of tightening or loosening. It is necessary to assemble and combine the components of various industries by the screw firmware. The general industrial products need to use each due to structural differences. Screws are assembled and fixed with different torsion forces, such as heavy industry such as aviation, shipbuilding and cars. Their components can be assembled with considerable strength to achieve a solid structure, withstand the impact of air pressure and power, while precision industries such as In electronic machinery, its components cannot be assembled with excessive torque to ensure its precise operation. However, no matter what kind of industrial products, less than one point of torque or more than one point of torque when combined with a screw is likely to cause a structure. The screw is ineffective or damaged, and the wrench tool is the key to controlling the torque.
