The molding machine further includes an adjusting seat mounted on the base unit and movable relative to a threaded shaft that is rotated by a power supply, a swing arm connected pivotally to the adjusting seat, a linkage unit having opposite end parts that are connected pivotally and respectively to a pivot portion of the swing arm and one of the holding arms, and another linkage unit having opposite end parts that are connected pivotally and respectively to another pivot portion of the swing arm and the other one of the holding arms. The swing arm is swingable through the movement of the adjusting seat so as to swing the holding arms by virtue of the linkage units. |
