The utility model relates to a labor-saving structure of a gardening shear.The utility model comprises a first grip and a second grip.The first grip is pivoted with a blade.And the blade extends to the other end with a piece of body.And a connecting block is convex on the inner walls of both sides of the second grip.A roller is pivoted between the two connecting blocks.And a guide angle is arranged near the roller of the connecting block.The piece can be pushed on the roller when the first grip and the second grip are pressed.The roller is used to form rolling contact.Thus, the collision damage between the sheet body and the roller is eliminated.It can effectively reduce friction consumption.At the same time, the connecting blocks on both sides of the roller form a guide angle.And the guide vane body slides to the roller by the guide angle.So as to prevent the sheet from not really pressing against the roller due to looseness,In order to improve its durability.一種園藝剪省力結構，其包括有：一第一握柄及一第二握柄，該第一握柄處樞設有一刀刃，且該刀刃向另一端延伸有一片體，又該第二握柄於兩側內壁處皆凸設有一連接塊，並於兩連接塊之間樞設有一滾輪，又該連接塊鄰近滾輪處皆設有一導角，該片體於握壓第一握柄與第二握柄時能推壓於該滾輪上，並利用滾輪形成滾動接觸，藉此消除片體與滾輪的碰撞損壞，並能有效減少磨擦消耗，同時該滾輪兩側之連接塊皆形成有一導角，並由導角導引片體滑向滾輪，藉此防止片體因為鬆動而未確實抵壓該滾輪之情況，俾以提高其耐用性。
