三角形阶梯垫铁(如图),用来调整压板高度。垫铁台阶最低由10毫米开始,转第二面由15毫米开始,转第三面由20毫米开始,共有19个支承高度。可以在100毫米范围内自由选用所需台阶之高度。如超出100毫米范围,还可在下边加垫一般的平行垫铁来弥补。台阶深为8.3毫米,既可满足压板的使用,又可保证60°小斜面有近1毫米的宽度,以免压坏工作台面。垫铁中心有ф35孔,可减轻重量,手拿又方便。因两侧磨平,还可作平垫铁用。 Triangle ladder horns (pictured), used to adjust the platen height. The horns steps start at a minimum of 10 mm, turn the second side by 15 mm and turn the third by 20 mm, with a total of 19 support heights. The height of the required step can be freely chosen within 100 mm. Such as beyond the scope of 100 mm, but also below the pad plus parallel general horn to make up. Step depth of 8.3 mm, not only to meet the use of pressure plate, but also to ensure that 60 ° small bevel nearly 1 mm width, so as not to crush the work surface. Horn center ф35 hole, can reduce weight, hand and convenient. For both sides polished, but also for flat horn.
