Tool sellers dropping drink at the front (6)
I believe the answer is:
pliers
'tool' is the definition.
(pliers is a kind of tool)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pliers that I've seen before include "Workmen's tools" , "Gripping tool with two serrated jaws" , "Tool with jaws for gripping small objects" , "taxi-drivers, say" , "Gripping tool, kind of pincers" .)
