Description

Special tool for shearing grafting blade

Technical Field

The utility model relates to a cutting means, concretely relates to specialized tool who shears the grafting blade before being exclusively used in the grafting.

Background

The development of the Korean pine seed industry has wide development space and good development prospect, and has great economic potential. Therefore, enthusiasm for cultivating clonal fruit forest of Korean pine is increased in various places in the northeast, and development momentum of Korean pine grafted seedlings is high. With the increasing grafting workload, the use problem of grafting tools is also highlighted. In the process of breeding large-batch red pine grafted nursery stocks, in order to solve the problems of large scion loss, uneven breeding nursery stocks, low production efficiency and the like caused by using a common grafting cutter, an operator adopts a thin and sharp double-edge razor blade with good flexibility and carries out corresponding modification on the razor blade, a special cutter handle is added, the modified cutter can be used for quickly cutting into the medullary part of the scion and smoothly completing sectioning along the medullary part at one time, the smoothness is high, the cutting surface is flat, no slow cutter is used, the working efficiency can be greatly improved, and the scion loss quantity can be reduced. A double-edged razor blade for a special cutter needs to be used by being cut in half from the middle. Although it is convenient to directly break the blade from the middle by hand, the fracture is irregular, and the installation and the use of the blade can be influenced. And the blade is thin and sharp, and the hand is easily injured in the breaking process. The blade has high hardness, and the cutting edge can be damaged quickly by using a common shearing tool. When the grafting workload of the Korean pine nursery stocks is large, the blade is kept sharp all the time, the blade is consumed quickly, the replacement speed is also quick, and the problem of the requirement of a special grafting blade shearing tool is more prominent.

Disclosure of Invention

The utility model aims to solve the technical problem that: aiming at the problems, the special cutting tool for the grafting blade is provided.

The technical solution of the utility model is that: grafting blade cuts specialized tool, include two handles that are "V" font and link together through the articulated shaft in one end, every the handle is in the position that is close to the articulated end all in front and back through the fix with screw two shear blades, shear the blade and be square, two liang of cooperations of four shear blades on two handles to be the scissors form interlock through the blade at edge and realize the shearing function, wherein be equipped with two locating pins between two shear blades of one side handle, the position of two locating pins corresponds with two installation locating holes on the twolip razor blade, after twolip razor blade laid the handle of one side through two locating pins, just can utilize shear the blade to divide it into two from the middle.

The technical effects of the utility model are that: the double-edge shaver has the advantages of reasonable structural design, convenience and quickness in use, high rigidity of the shearing knife opening, easiness in replacement of the shearing knife, low use cost, safety, reliability and the like, and can complete shearing operation of a large number of double-edge shaver blades. The cut of the sheared blade is regular, the blade cannot be arranged on a special knife handle, and the shearing efficiency of the double-edge shaver blade can be greatly improved. The shearing blade can be a square hard alloy lathe blade special for a machine tool, can be conveniently purchased in the market, and has low cost. The square lathe blade is adopted, and each blade is provided with four cutting edges which can be used alternately, so that the lathe blade is very durable. The blade supporting plate of the shaver can prevent the blade from falling off, namely, the blade can be prevented from hurting hands during operation, and the process of picking up the blade can be prevented from hurting hands.
