摘要: A mandrel assembly is provided for use with a tube bender including a mandrel rod, a mandrel ball, and a coupler. The coupler is configured to couple the mandrel ball to the mandrel rod and includes a link, a first connector member, a second connector member, and a retainer. The link includes a body and a collar. The first and second connector members are positioned to lie over the second end of the body and cooperate to define a groove sized to receive the collar of the link and a socket sized to retain a projection of the mandrel ball. The retainer is positioned to lie over the first and second connector members and the link to secure the first and second connector members to the link.
