Tool socket

A tool socket comprising:

• a body including an accommodation groove defined in a lower end of the body, a fitting orifice formed in an upper end of the body and communicating with the accommodation groove;
• an elastic operation assembly accommodated in the body, and the elastic operation assembly including a locking seat on which multiple apertures are arranged in a honeycomb shape so as to accommodate multiple elastic hexagonal columns individually;
• wherein the accommodation groove has a hexagonal wall arranged therein, and six toothed spaces respectively extend outward from six corners of the hexagonally wall of the accommodation groove, two inverted isosceles-trapezoid projections extend inward from each of six sides of the hexagonal wall of the accommodation groove and are separated by an isosceles trapezoid space which extends outward from each side of the hexagonal wall of the accommodation groove;
• wherein the locking seat is formed in a toothed hexagon shape and has six toothed bulges respectively extending outward from six corners thereof and corresponding to the six toothed spaces of the accommodation groove of the body, two inverted isosceles-trapezoid recesses defined on each of six sides of the locking seat and are separated by an isosceles trapezoid projection which extends outwardly from each side of the locking seat;
• wherein said two inverted isosceles-trapezoid recesses correspond to said two inverted isosceles-trapezoid projections separately, and the isosceles trapezoid projection corresponds to the isosceles trapezoid space.
