    摘要： First and second dies are movably opposed to each other. The second die is for pinching a package and a lead wire of the package in cooperation with the first die with a portion of the lead wire that protrudes from the first and the second dies. A slidable base is slidably supported on a die surface of the first die and has an inclined surface. A base pushing rod is movable in a direction which is substantially perpendicular to a base surface of the slidable base. The base pushing rod has an inclined rod surface which is opposed to the inclined surface. A spring urges the slidable base to make the inclined base surface be brought into contact with the inclined rod surface. The base pushing rod moves the slidable base towards the package together with one end portion of the lead wire that is supported on the slidable base when the protruded portion of the lead wire is pushed by the wire pushing member. The slidable base may have a cam follower internal surface which defines a cam hole. In this case, a cam roller is inserted in the cam hole. The slidable base may be moved by the cam roller.

    摘要翻译： 第一和第二模具可移动地彼此相对。 第二模具用于与第一模具配合地夹紧包装的包装和引线，引线的一部分从第一和第二模具突出。 可滑动的基座可滑动地支撑在第一模具的模具表面上并且具有倾斜表面。 基座推杆可在基本上垂直于可滑动底座的基面的方向上移动。 基座推杆具有与倾斜表面相对的倾斜杆表面。 弹簧促使可滑动的基座使倾斜的基面与倾斜的杆表面接触。 当引线的突出部分被线推动构件推动时，基座推杆将可滑动底座与引导线的支撑在可滑动基座上的一个端部一起移动到封装件。 可滑动的底座可以具有凸轮从动件内表面，其限定凸轮孔。 在这种情况下，凸轮辊插入到凸轮孔中。 可滑动的底座可以由凸轮辊移动。
