ABSTRACT:
TECHNICAL FIELD
The present invention relates generally to a socket wrench, and more particularly to an adjustment structure of a lighting device of the socket wrench.
BACKGROUND ART
Conventional socket wrenches are generally devoid of a lighting device. As a result, it is often difficult for a user of the conventional socket wrench to maneuver in a dark or poorly-lit place. Some of the conventional socket wrenches are equipped with a lighting device, which can not be adjusted in its angular position. In light of the lighting device of the conventional socket wrench being fixed in its position, such a conventional socket wrench is not helpful in a situation calling for illumination because it does not facilitate the operating of the conventional socket wrench in a poorly-lit work place.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a socket wrench with a structure capable of an angular adjustment of a lighting device of the socket wrench. The adjustment structure comprises a conductive tension element, a conductive ring member, a conductive cylinder member, a press control element, and a rotation frame. In light of the current loop which can be adjusted at an angle, the illumination angle of the lighting device of the socket wrench of the present invention can be adjusted with ease and speed.
