可以说的，a pair of hands的字面意思是“一双手”，也可引申指“能帮忙做事的人”。如：

Give me a chance! I've only got one pair of hands you know! 别太着急！你知道我只有一双手！

With the best will in the world, the job is too much for one pair of hands. 无论费多大力气，但凭一双手也没法应付这工作。

We need an extra pair of hands if we’re going to finish on time. 要想按时完成，我们就要再增加一个人。

另外，a safe pair of hands还可以表示“信得过的人”（=someone who you can trust to do an important job well, without making mistakes）。如：

We can use another pair of hands to help us wrap gifts for the holidays. 我们可以找个人来帮我们包这节节日礼物。
