Background

Electric tools, such as hand-held lithium electric tools, electric wrenches, etc., are provided with lighting fixtures to facilitate users working in dark environments. The existing lighting lamp is mainly designed in such a way that light rays of the lamp are horizontally emitted from an output end of an electrician tool, so that the light rays can vertically strike the surface to be drilled to form a lighting area, and the structure is mostly represented by arranging the lamp above a switch.

Secondly, current lighting fixtures are either exposed or are wrapped with only one transparent piece. The exposed design easily causes the peripheral diffusion of the light source, so that the illumination brightness finally formed on the surface to be drilled can not meet the illumination requirement; although the design of wrapping with transparent parts can block partial diffusion of the light source, the design still cannot provide enough illumination brightness, and cannot meet the working requirements of users in dark environments.
