Abstract
A clutch mechanism for a hand tool comprises a body with a converging internal wall surface which is mounted on a rod. The body houses a set of ball bearings which are biased along the converging wall into an engaged position with a rod passing through the body. An axial force applied to one end of the body causes the balls to grip the rod. Whereas a force applied to the other end of the body releases the balls from the rod.
