Description

Technical Field

[0001] The utility model relates to the technical field of fruit tree grafting tools, in particular to a fruit tree grafting knife. Background Technique

[0002] A fruit tree grafting knife, especially a persimmon tree grafting knife, is composed of a knife handle and two blades symmetrically fixed on both sides of the knife handle, parallel to each other and with the same blade direction. It is very practical in the hot season from July to September. Based on following the "I"-shaped budding of persimmon tree seedlings, it can determine the upper and lower distances with one knife; at the same time, when implementing the "mouth"-shaped budding on the thicker branches of persimmon trees, it can determine the "mouth"-shaped cut surface with two knives, greatly shortening the time for the scion and the bud cut surface to be exposed outside, and playing a role in making the two closely contact, effectively improving the grafting speed and survival rate of persimmon trees.

[0003] However, the existing persimmon tree grafting knife has a simple structure and single function, is not convenient for adjusting the lifting of the two blades and storing according to the needs of use. Moreover, when it is necessary to operate with one blade, it is not convenient to store the other blade, resulting in a small range of use of the grafting knife and not being able to well meet the use requirements. Therefore, a fruit tree grafting knife is proposed. Content of the Utility Model
