双头螺栓一般用两个螺母拼紧一头丝扣的方法来拆装,比较费工。有时双头螺栓丝扣与机体锈死,很难拆卸。我们改用一个工具(如图示),来拆装双头螺栓,其结构简单,操作穷便、工效较高。工具由手柄1、壳体2、带齿偏心轮3、螺杆4等组成。壳体用30号钢制作,上端φ10.5毫米孔可插入手柄,下面φ50毫米圆台上开一宽14毫米的半圆槽,供安装带齿偏心轮用。拆装时为避免将双头螺栓 Studs generally use two nuts to fasten a screwdriver method to disassembly, more labor. Sometimes stud bolts and the body rust, it is difficult to disassemble. We use a tool (as shown) to disassemble and remove the studs. The structure is simple, the operation is poor, and the work efficiency is high. Tools by the handle 1, shell 2, with eccentric gear 3, 4 and other components. Shell made of steel 30, the upper φ10.5 mm hole can be inserted into the handle, the following φ50 mm round table open a 14 mm wide semi-circular groove for the installation of cogged eccentric wheel. To avoid the double-headed bolts when disassembly
