  • Quick return mechanismWikipedia

    A quick return mechanism is an apparatus to produce a reciprocating motion in which the time taken for travel in return stroke is less than in the forward stroke. It is driven by a circular motion source (typically a motor of some sort) and uses a system of links with three turning pairs and a sliding pair.. Quick return is a common feature of tools in which the action is performed in only
