在农机修理中,经常为拆装双头螺栓而伤脑筋。虽然有过这样或那样的拆装工具,不是因不耐用而被淘汰,就是因结构复杂而被放弃。有些螺栓因其位置的限制,即使用管钳也不易拆装。用双螺母并紧的方法拆装,费时费力,有时因螺栓锈蚀,不但拆不掉,还易造成螺杆螺母一起报废。为此,我们制作了一种新型双头螺栓拆装器,实践证明使用 In agricultural machinery repair, often for the disassembly studs and headache. Although one or more disassembly tools have not been eliminated because of being unforgiving, they have been abandoned because of their complicated structure. Due to the limitation of the position of some bolts, they can not be disassembled even with pipe wrenches. With double nuts and tightening method disassembly, time-consuming and laborious, and sometimes due to bolt corrosion, not only can not afford to demolish, but also easily lead to screw nuts together scrapped. To this end, we have produced a new type of double-headed bolt disassembler, proved to be used
