Abstract
A tool changer for a machine includes a disc having a number of protrusions extended radially outward and a number of grooves formed between the protrusions. A rod has a projection for engaging with the grooves of the disc and for precisely rotating the disc step by step when the rod is rotated. The protrusions each includes a curved rib. The rod includes a stud and one or more stops for engaging with the curved rib and for retaining the curved rib and the disc in place when the projection does not rotate the disc.
