Torque socket having torque value indication

A torque socket having torque value indication, including:

• a main body, one side thereof axially disposed with an insertion part allowing a rotation tool to be inserted and another side thereof axially formed with an accommodation slot, wherein a combination hole is formed in said accommodation slot, at least one guiding tenon and a hollow slot are radially disposed and formed on an outer circumference of said accommodation slot, and an indication ring capable of shielding said hollow slot is axially fastened on said outer circumference of said accommodation slot, an outer circumference of said indication ring is annularly provided with a plurality of torque value marks;
• a torque adjusting assembly, including a spring and a shaft cylinder disposed in said accommodation slot, wherein said spring is disposed between an inner wall of said accommodation slot and said shaft cylinder, one side of said shaft cylinder is formed with a sleeve slot protruded out from said indication ring and allowing a drive head to be sleeved, and an outer circumference of said shaft cylinder is radially formed with at least one arc-shaped guiding slot arranged at at least one location corresponding to said at least one guiding tenon and allowing said at least one guiding tenon to be inserted, said shaft cylinder further includes a torque fine tuning device which has a shaft tube axially extended in a direction opposite to said sleeve slot, an outer circumference of said shaft tube is formed with an adjusting thread segment, an adjusting ring is threaded with said adjusting thread segment, so that said adjusting ring is arranged to be adjacent to said spring, said adjusting ring is located in said hollow slot, and an outer circumference of said adjusting ring is annularly formed with a plurality of rod holes allowing a pry tool to be inserted;
• a connecting member is utilized for passing said sleeve slot and said spring and received in said combination hole, said adjusting ring is able to axially compress or release said spring for adjusting a torque value;
• and
• an end cover ring, combined at said outer circumference of said accommodation slot, wherein an indication mark is formed at an outer circumference of said end cover ring;
• when an object to be locked is fastened and locked by said drive head, said at least one guiding tenon of said main body is displaced along said arc-shaped guiding slot of said shaft cylinder, a part of said shaft cylinder is retracted into said accommodation slot, a part of said end cover ring is retracted into said indication ring, and said adjusting ring is served to compress said spring, so that said indication mark is aimed at one of said plurality of torque indication marks for displaying a locking torque value of said object to be locked.
