优选的，所述压缩弹簧包括第一接触端、第二接触端和弹簧本体，所述弹簧本体由一长条形金属或树脂环形绕转而成，且呈螺旋状，所述弹簧本体上设有多个等间距的螺旋圈体，所述第一接触端和第二接触端分别设置在弹簧本体的顶部和底部，且所述第一接触端、第二接触端均为水平面；所述第一接触端固定连接挡块，所述第二接触端固定连接上模。
优选的，所述整形柱下端部采用半球形结构；所述整形针下端部为锥形结构。
优选的，所述上模和下模均由亚克力材料制成。
与现有技术相比，本实用新型的有益效果是：
(1)本实用新型结构设计新颖，使用方便，能够实现对集成电路IC引脚的快速整形，提高了后续IC焊接的质量。
(2)本实用新型采用的压缩弹簧受力均匀，受力后不易发生变形，能够实现快速复位，进一步提高了工作效率。
