Pruner with geared mechanism

A pruner comprising:

• a first unit having a first blade at a front portion thereof, a first pivot hole at a middle-front portion thereof, a first sliding groove at a middle-rear portion thereof, a first transmission gear at a middle portion thereof and positioned for engagement with a second transmission gear of a driving unit, and a first handle at a rear portion thereof;
• a second unit having a second blade at a front portion thereof, a second pivot hole at a middle-front portion thereof, a second sliding groove at a middle-rear portion thereof, and a third pivot hole at a rear portion thereof;
• and
• the driving unit having the second transmission gear at a front portion thereof, a fourth pivot hole at a middle portion thereof and a second handle at a rear portion thereof;
• wherein:
• the first unit is pivotally connected to the second unit by aligning the first pivot hole with the second pivot hole to allow connection by a first pivot unit;
• the second unit is pivotally connected to the driving unit by aligning the third pivot hole with the fourth pivot hole to allow connection by a second pivot unit;
• and
• the second blade of the moveable unit is driven by the second handle of the driving unit through the engagement of the second transmission gear and the first transmission gear to pivotally move toward the first blade to complete a cut;
• and
• wherein, when the first handle and the second handle are closed, the first sliding groove overlaps with the second sliding groove, and as the second handle, a relative position between the first and second sliding grooves changes, thereby altering a location of the overlap or decreasing a degree of the overlap.
