求助：专业英语

tong 煤钳,火钳 (那种长长的)，方糖夹，冰块夹

plier 钳子(如老虎钳,手钳,扁嘴钳等); 镊子

因而姑且推断，PILER的种类应该不少，其中也会有尖嘴型的，只是相比起来，PILER的体型要比TONGS短小一些吧，仅供参考了。

在看TONGS的解释：a device used for picking up objects, consisting of two “long” pieces joined at one end and pressed together at the other end in order to hold an object between them

pliers： a “small” tool with two handles for holding or pulling small things like nails, or for cutting wire

pliers指老虎钳
tongs一般指镊子，夹子类的

估计前者头是平的，后者是尖的
