Abstract

A radial force tool assembly has a first force-transmitting member with a first end with a first face and a second face, a first rear arm member having a first end face abutting the first face and a second end face, and a second rear arm member having a first end face abutting the second face and a second end face. The first end faces are curved so that when the first force-transmitting member moves towards the front, the first end face of the first rear arm member rolls on the first face, projecting the first rear arm member radially outwards in a first radial direction, and the first end face of the second rear arm member rolls on the second face, projecting the second rear arm member radially outwards in a second radial direction opposite the first direction while projecting the first and second rear arm members.
