CN105724062A - L-shaped dual-purpose bud grafting shear - Google Patents

Abstract

In the existing grafting technology, bud slices and stock are basically cut through a grafting knife; operation relies on the experience and proficiency of an operator, efficiency is not high, labor intensity is high, and the hands of the operator can be easily hurt; it is hard to ensure the shapes and sizes of the junction surfaces (gaps) between the bud slices and the stock, attachment is not tight, and the grafting survival rate is affected. The grafting shear is an L-shaped dual-purpose bud grafting shear composed of a clamping mechanism and a cutting mechanism. The clamping mechanism and the cutting mechanism are connected together perpendicular to each other in an L shape, the design is unique, and identical or similar bud grafting shears are not available on the domestic market. The clamping mechanism plays the role of clamping branches to replace the function of holding the branches by hand. The cutting mechanism replaces the function of holding the grafting knife by hand. Two vertical knives and one rotary cutter work cooperatively, and uniqueness is achieved. The cutting mechanism plays the role of cutting the bud slices on scions and cutting graft unions in the stock, and therefore the shear achieves two purposes. During operation, the operator holds a clamping handle with one hand to clamp the branches, and rotates a cutting handle with the other hand to cut off the bud slices, and operation is precise, safe and efficient.
