Transcription
Description
A commonly produced version consists of a weighted base, a pair of twice-adjustable arms ending in crocodile clips, and optionally a magnifying glass, held together by flexible joints. It is usual to work with an additional table lamp and there are also some third-hand models, with light already incorporated.[2]
Purpose
The clips are used to hold a light workpiece in place while the joints allow the user to change the position or angle. Sometimes helping hands are augmented with modules from the adjustable coolant hose systems used with machine tools.[3]
