socket nut wrench

基本解釋

The key to success with a socket wrench is pattern matching: The socket must match the nut.
成功使用套筒扳手的關(guān)鍵在于模式匹配：套筒扳手必須與螺母相匹配。
When it does, a socket wrench is much more effective at loosening a nut from a bolt than a hammer.
如果匹配，那么用套筒扳手來(lái)擰開(kāi)一個(gè)螺母肯定比用錘子方便。
Otherwise, you might feel as if you are using a socket wrench as a hammer hitting the handle of a screw driver to loosen a nut and bolt.
否則，您可能感覺(jué)到像用錘子一樣使用一個(gè)套筒扳手來(lái)敲擊螺絲刀手柄而擰開(kāi)螺栓的螺母。
