ABSTRACT:
A socket wrench extension includes an axial bore for receiving a rod and includes an opening and an orifice for receiving a ball and an actuator. The actuator includes a tapered surface for moving the rod inward of the axial bore. The rod includes an aperture for engaging with the actuator and a cavity for receiving the ball. A spring biases the rod to move the ball partially outward of the opening so as to engage with a socket member. The ball is received in the cavity when the rod is moved inward by the actuator. The elements may be easily assembled in the extension.
