    • A pair of pliers is provided for perforating small cards, which pliers have two double-arm levers which can be pivoted about a geometrical transverse axis and whose end zones, which serve for perforating, each have a plane, which planes are parallel to the transverse axis and which, in the closed state of the pliers, are approximately parallel to each other. Vertically positioned in one plane is at least one punching pin, to which there corresponds in the opposite end zone a punched hole which is vertical to the plane of the latter. There are provided two positioning pins in one end zone vertically to the plane thereof, which pins are, measured in one of the two main planes, at a specific center distance from the transverse axis. In one end zone, there is provided a first coding box and in the other end zone, there is provided a second coding box, which boxes contain the punching pin and the punch hole respectively, the coding box being sufficiently smaller in dimension, with respect to symbol identification, in the direction that is parallel to the positioning pins than the positioning pin.
    • 提供一对钳子用于穿孔小卡片,钳子具有两个双臂杆,其可以围绕几何横向轴线枢转,并且其用于穿孔的端部区域各自具有平面,该平面平行于横向 并且在钳子的关闭状态下,彼此大致平行。 在一个平面中垂直定位的是至少一个冲压销,在相对端区域中与其相对应的冲压孔垂直于后者的平面。 在垂直于其平面的一个端部区域中设置有两个定位销,该销在两个主平面中的一个中以与横向轴线的特定中心距离测量。 在一个端部区域中,设置有第一编码盒,在另一端区域中设置有第二编码盒,该盒子分别包含冲孔针和冲孔,编码盒的尺寸足够小,相对于 在与定位销平行的方向上进行符号识别。
