Description

Grooving cutter for orange tree grafting Technical Field The utility model relates to the technical field of fruit tree grafting tools, in particular to a slotting cutter for citrus tree grafting. Background Grafting is a means for cultivating and breeding plants, by grafting stems and buds of corresponding plants on the trunk of another plant, especially in the process of grafting citrus trees, the rapid growth of grafted seedlings can be facilitated, the productivity is increased, along with the development of society, a plurality of novel high-position grafting treatments of citrus trees are successively put into the market, When the citrus tree is grafted, the trunk is required to be grooved by using a grooving cutter, the traditional grooving cutter is of a single-edge structure, the thickness of the cutting edge is uniform, stress is concentrated during splitting, the splitting depth can be accurately controlled, stock splitting or excessive splitting is avoided, and the included angle between the cutter handle and the cutting edge is usually 120-135 degrees, so that the method accords with ergonomics, is convenient for a grafting master to exert force, and reduces operation fatigue. However, when slotting the citrus trees, the wrists of the users continuously exert force, so that hand fatigue is easily caused, and the slotting cutter is caused to drop from the hands, so that potential safety hazards are increased, moreover, the slotting cutter is easy to passivate after long-time use of the cutting edge, the external sharpening stone is required to be used for sharpening the citrus trees, and the traditional sharpening stone is large in size and inconvenient to carry, so that the grafting efficiency of the citrus trees is affected. Disclosure of utility model The utility model aims to solve the problems that in the prior art, a slotting cutter is inconvenient to position a hand of a user, and the slotting cutter is easy to fall off from the hand after the hand of the user is tired, so that potential safety hazards are increased.
