Description

Technical Field

[0001] The utility model relates to a special grafting shear, in particular to a split grafting rootstock shear for grafting. Background Art

[0002] Grafting is widely used in the horticulture and gardening industries, and is often used for breeding seedlings, updating varieties, horticultural shaping, preserving germplasm, etc. Split grafting is the most commonly used grafting method. Currently, for the treatment of rootstocks in split grafting, usually a split grafting knife is used to split the rootstock by hand pressure, or the rootstock is split by hitting it from above against the rootstock, and some use pruning shears to cut the rootstock horizontally. After splitting the rootstock, the prepared scion is inserted into the split seam according to the operation requirements and the cambiums are aligned, then the tool or scissors are withdrawn, and fixed materials are used for binding. Currently, the method of treating rootstocks with a split grafting knife has relatively complex operations, requires a high level of proficiency in operation, and has certain risks. Although using pruning shears to treat rootstocks is relatively convenient and safe, the handle and the head of the pruning shears are in a straight line. After splitting the rootstock, the handle is directly above the split, which hinders the subsequent insertion operation of the scion. Some people also slightly open the handle at an angle to create an operating space, but due to the structure of the tool itself, it is impossible to create a very generous space, and it requires a higher control ability from the operator. If the handle is opened too much accidentally, the cutting edge will be pulled out of the cut, and the tool needs to be inserted again for re-operation. Moreover, the fixed blade of the pruning shears is arc-shaped, which is difficult to hold against the branch. When dealing with a relatively thick rootstock, the rootstock bark will be damaged when the tool is withdrawn. Some operators, to avoid damaging the bark, will pull out the tool forcefully obliquely upwards. When this operation is carried out in the air, such as on a tree or on a ladder or a stool, it will increase the operation difficulty and even pose a danger. Summary of the Utility Model

[0003] The purpose of the utility model is to address the above-mentioned defects existing in the prior art, and provide a split grafting rootstock shear for grafting. On the one hand, through the cooperation of the moving blade and the fixed blade connected at 90 degrees, it is convenient for the operator to cut the rootstock, and then insert the scion smoothly into the grafting opening. On the other hand, since a fulcrum with an arc structure is provided at the lower end of the fixed blade, it is convenient to quickly withdraw the moving blade from the rootstock, making the split grafting operation simpler and easier, and reducing the risk of operation.

[0017] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] Example 1, referring to Figures 1 - 5 , a split grafting rootstock shear mentioned in the present invention includes a handle, a pin screw 5, a fixing nut 6, and a return spring 7. The front part of the handle is movably connected through the pin screw 5 and the fixing nut 6, and the return spring 7 is installed in the middle of the handle. Among them, the handle is composed of a moving blade handle 3 and a fixed blade handle 4, and a moving blade 1 is provided at the front end of the moving blade handle 3, and the moving blade 1 is connected to the moving blade handle 3 at a 90-degree angle. A fixed blade 2 is provided at the front end of the fixed blade handle 4, and the fixed blade 2 is connected to the fixed blade handle 4 at a 90-degree angle. In this way, the closing action of the moving blade handle 3 and the fixed blade handle 4 in the horizontal direction is converted into the splitting action of the upper end of the rootstock 9.

[0019] Referring to Figure 5 , the outer side of the moving blade 1 mentioned in the present invention is the back of the knife 1.1, and the inner side of the moving blade 1 is the blade edge 1.2 with an arc structure, and the blade edge 1.2 with an arc structure is used to cut into the rootstock 9 to form a grafting interface.

[0020] Referring to Figure 5 , a notch 2.1 with a right-angled structure is provided at the front end of the fixed blade 2 mentioned in the present invention, which is used to cooperate with the inner side of the moving blade 1 to form a shearing action and is convenient for abutting against the edge of the rootstock.

[0021] In addition, the lower part of the above-mentioned fixed blade 2 is provided with an arc structure 2.2 at the rear side of the lower end, which is used as a fulcrum with the arc structure to conveniently extract the moving blade 1 from the split rootstock 9 of the grafting interface.

[0022] Furthermore, the rear end of the above-mentioned fixed blade handle 4 is movably connected to a fixed locking hook 8, and the lower part of the fixed locking hook 8 cooperates with the moving blade handle 3 to lock.

[0023] When the utility model is in use, an operator stands beside the rootstock to be cleft grafted, holds the rootstock with one hand, and operates to open the moving blade handle 3 and the fixed blade handle 4 with the other hand, so that the notch 2.1 of the right-angled structure of the fixed blade 2 abuts against the outer edge of one side of the rootstock, and the blade 1.2 of the arc-shaped structure of the moving blade 1 faces the outer edge of the other side of the rootstock. Then, hold the moving blade handle 3 and the fixed blade handle 4 tightly, so that the blade 1.2 of the arc-shaped structure cuts into the rootstock 9 to form a cleft grafting opening; then, insert the scion 10 into the cleft grafting opening. Finally, with the arc structure provided at the lower end of the fixed blade as a fulcrum, it is convenient to extract the moving blade from the rootstock, realizing that cleft grafting is simpler and easier to operate, reducing the risk of operation, improving the one-time success rate of the grafting action, and also improving the efficiency;

[0024] Among them, the moving blade is arc-shaped and is relatively easy to cut into the rootstock to split the grafting opening; moreover, the cutting head and the handle form an angle of about 90°, easily yielding the working space and making it convenient for the scion to be inserted into the interface; the whole process has a support, saving effort and being safe.

In this way, the closing action of the moving blade handle 3 and the fixed blade handle 4 in the horizontal direction is converted into the splitting action of the upper end part of the rootstock 9.

[0026] The difference from Example 1 is that:

[0027] The notch of the right-angled structure at the front end of the fixed blade 2 mentioned in the utility model is a blunt surface structure, and it contacts the outer edge of the rootstock 9 through the blunt surface structure. This structure mainly relies on the moving blade to complete the splitting action of the rootstock.
