摘要

The T-shaped socket wrench has a lateral bar (20), with a sliding piece (30) on it with an axial passage drilling (34) fitted with a pressure spring (35) and an inhibitor pin (36) with a rounded head (361) and a curved recess (362). When the pin head is not under pressure from the lateral bar, the pin recess and a conical opening (321) are aligned in a straight line and a ball (33) enters the recess and the socket wrench is not clamped and is separated from the connecting cube (32). When the lateral bar is pressed, the ball is forced outwards to give a clamping action on the socket wrench at the connecting cube.
