考虑连杆螺钉的作用；
连杆螺钉在加工完成后成品交验前，要求进行预拉伸试验。
Before completing linkage screw in the machining, finished products are needed to do the pre-tensile test.
该实用新型设计，实现了连杆螺钉的拉伸及伸长量的精确控制，有较好的生产实用价值。
The new design has realized stretching and precise control of elongation, which have better value in production and use value.
