The invention provides a drection-variable linkage type plug seedling cuttage gripper and belongs to the field of agricultural automation seedling transplanting equipment. The gripper comprises spring sheets, spring sheet mounting blocks, gripper clamping blocks, gripper supporting plates, top rods, gripper supporting plate mounting frames, rod claw mounting blocks, a rotating shaft, a top plate, a lower cylinder, a seedling carrying plate mounting block, a top rod mounting block, a seedling carrying plate, a cylinder-seedling conveying plate mounting block, a sleeve, an upper cylinder, a linear bearing, a bearing, a bearing mounting seat, a rotary motor, a coupler, a motor mounting seat and a linear guide rail. The spring sheets are cuttage seedling gripping parts of the gripper; each gripper comprises two spring sheets. The gripper is capable of directly carrying out cuttage of a row of flower seedlings at the same time; meanwhile, the cuttage conditions of the flower seedlings can be adjusted; the cuttage consistency is ensured while the damage to the flower seedlings can also be avoided; and meanwhile, the gripper is simple and stable in structure, high in automation degree, and has a relatively high application value.
