거수기 (擧手機) is a disparaging term that literally means a lifting (擧) hand (手) machine (機). It is used to refer to politicians who vote the way their party leaders tell them to vote rather than according to their own personal views. In other words, such politicians are like machines who automatically raise their hands to vote for whatever their party leaders tell them.
By the way, Koreans used to use a piece of equipment called a 거중기 to lift heavy objects. The word 거중기 (擧重器) literally means a lifting (擧) heavy [objects] (重) instrument (器). The Chinese character 機 (기), which means machine, can substitute for the character 器 (기).
