While clamps (also known as vices) are tools used in a workshop, the clamp emoji is more likely to be used metaphorically than literally. Since the clamp is also known as a vice, it could work as a double entendre to refer to bad habits that put someone in a bad position. Or, it could be used in a kinky bondage way!
