A swinging mechanism for workpiece holding members of a nut former includes a drive rod to swing a swinging member which is connected to a plurality of seats to support the workpiece holding members. The swinging member is connected to the machine body with two connecting members which are pivoted to the machine body with two first pivot shafts. An elongated crank support member to support cranks which actuate the workpiece holding members is mounted on a pair of connecting members which swing about two second pivot shafts respectively adjacent to the first pivot shafts. Two eccentric members are respectively mounted on one of the first pivot shafts and one of the second pivot shafts, and a third connecting member is mounted on the eccentric members. The movement of the swinging member is transmitted to the crank support member through the first, second and third connecting members. |
