闭锁式的 meaning in English

closed-end

For example an open ended 9 / 16th wrench is very similar to a 9 / 16th 6 - point closed - end wrench but the 6 - point closed end wrench is far better suited for removing extremely tight and even stuck nuts and bolts than is an open - ended wrench of the same size
举个例子，一个开口端是9 / 16的扳手，它与闭锁式的9 / 16 . 6的扳手非常相似，但是差6个点的扳手远远要比能拧得很紧的扳手要好用的多，一个能粘装订书的工具要比一个开口端的扳手要好用得多。
