Abstract
A garden shear includes a cutting blade formed on a lever. A plate is pivotally coupled to the lever and has a cutting blade for acting with that of the lever. The plate includes one or more engaging notches formed opposite to the cutting blade. A beam is pivotally coupled to the lever and can be moved toward and away from the lever. A hook is pivotally coupled to the beam for engaging with the plate and for moving the cutting blades away from each other. An arm is pivotally coupled to the beam and includes one end for engaging with the engaging notches and for allowing the cutting blades to be moved toward each other step by step.
