升降貨梯上用六角螺母是什么原因？

升降貨梯http://m.8kvv.com/上安裝螺母的部位，有時(shí)并不是足夠?qū)捲?，且擰螺母的扳手的空間也相當(dāng)狹小。六角形的螺母，一次只需要把扳手扳動(dòng)60度，就能夠慢慢把螺母擰緊，為了擰緊螺母所需要留出的地方，六角形更小，因此六角形螺母使用起來(lái)最為方便。
Freight elevator on the site of the mounting nut, sometimes not enough well-off, and tighten the nut wrench space is quite small. Hexagonal nut, one just need to flip the lever 60 degrees, it is possible to slowly tighten the nut,tighten the nut to the desired place set aside, hexagonal smaller, and therefore the most convenient to use the hexagonal nut.

再看看升降貨梯http://m.8kvv.com/扳手，普通扳手的柄與扳口都可以成為30度的夾角，這樣當(dāng)升降貨梯上安裝螺母的地方十分狹窄，扳手也不可以自由活動(dòng)時(shí)，而六角螺母，只要將扳手扳動(dòng)一個(gè)螺母，再把扳手翻過(guò)來(lái)再扳一次螺母，這樣來(lái)回反復(fù)地扳幾次，就可以把螺母擰緊了。
Look at cargo lifter wrench, a common wrench handle and pull the port can become an angle of 30 degrees, so that when the nut is installed on local cargo lift very narrow, not when the wrench can be free, and hex nuts, as long as the wrench flip a nut, then turn it over and then pull a wrench nut, so pull back and forth several times repeatedly, you can put a nut tightened.
