[0002] At present, there are two main types of screwdrivers for daily use in the market, depending on the source of power: one is manual screwdrivers, which are cheap and easy to carry, but they rely entirely on the wrist when used. Long-term use will cause wrist soreness and arm weakness, which will affect the work. continue; although the electric screwdriver is easy to use and saves physical strength, its use is limited; and when the light is dark or the screw is in a deep hole, it generally requires the other hand to hold an additional lighting tool to work accurately and normally. It greatly affects the production efficiency, and sometimes even brings certain safety hazards

Although some screwdrivers with self-luminous lighting devices have been invented, their light sources are mostly placed on the handle of the screwdriver, and they still cannot provide effective lighting in some deep hole environments.
