Technical Field

[0001] The utility model relates to the technical field of grafting tools, in particular to a grape grafting quick opening device. Background Art

[0002] Grape grafting is one of the methods of artificial vegetative propagation of grapes. Specifically, it refers to grafting the branches or buds of grapevines onto the stems or roots of another plant, so that the two grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. People mostly use branch grafting, which is to closely combine the cambium of the scion and the rootstock to ensure the survival of the scion. Among them, the grafted branch is called the scion, and the grafted plant body is called the rootstock.

[0003] When grafting, you need to use a blade to cut horizontally from the middle of the rootstock along the length of the rootstock, so that the end of the rootstock is split into two halves to form a joint, and then the wedge-shaped scion is inserted into the joint to make the rootstock and scion perfectly combined.

[0004] However, when using a blade to cut a stock horizontally, one needs to hold the stock with one hand and use the blade to cut the stock with the other hand, which is difficult to operate and poses a safety hazard, and is easy to scratch the hand holding the stock. In addition, the distance of the blade's cross-section is difficult to control, and the stock is easily cut too much, affecting the self-healing of the stock. Utility Model Content

[0027] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0028] A grape grafting quick opening device in this embodiment relates to the technical field of grafting tools. By modifying pruning shears 100, an opening assembly 200 is provided on two shear handles 111, and the rootstock is opened from the side of the rootstock, which can eliminate safety hazards, control the degree of splitting of the opening, and optimize the grafting process.

[0029] See also Figures 1 to 3 A grape grafting quick opening device in this embodiment includes pruning shears 100 and an opening assembly 200. The pruning shears 100 includes two pruning tools 110 hinged to each other. The lower end of the pruning tool 110 is provided with a pruning handle 111, which can be convenient for human hands to hold. The upper end of the pruning tool 110 is provided with a knife head 112, which interacts with each other to cut branches.

[0030] The opening assembly 200 includes a cross-cutting knife 210 and an anvil 220. The cross-cutting knife 210 is fixedly connected to a shearing handle 111 and is arranged along the length direction of the shearing handle 111. The anvil 220 is fixedly connected to another shearing handle 111. The anvil 220 and the cross-cutting knife 210 are arranged in cooperation with each other. The two pruning knives 110 have an open position and a closed position. In the open position, the two shearing handles 111 are relatively open, and the anvil 220 and the cross-cutting knife 210 are relatively open, leaving a cross-cutting space for shearing the stock. In the closed position, the two shearing handles 111 are relatively parallel and spaced, and the cross-cutting knife 210 abuts against the anvil 220. The cross-cutting knife 210 can cut the stock from the side of the stock, split the end of the stock from two halves to form a plug-in seam, and the operation is relatively simple and safe, which optimizes the grafting process. In addition, the shear force of splitting the rootstock comes from the side of the rootstock, which can avoid the rootstock being excessively split along the length direction, affecting the grafting and healing of the rootstock.

[0031] During use, the stock is inserted into the cross-section space in the open position, and the two shear handles 111 are manually driven to move closer to the closed position. The cross-section knife 210 cuts into the stock and passes through the stock to abut against the knife anvil 220 to cross-section the stock.

[0032] In some embodiments, see Figure 1 and Figure 2 , a curved portion 113 is provided in the middle of the pruning tool 110, and the curved portion 113 is provided between the shearing handle 111 and the hinge of the pruning tool 110. The curved portion 113 can adjust the position of the shearing handle 111, so that the shearing handles 111 of the two pruning tools 110 in the closed position can be relatively parallel, thereby ensuring that the opening assembly 200 can be in the best working position. A compression spring 120 is provided between the two curved portions 113, and the two ends of the compression spring 120 are respectively connected to the two curved portions 113. When the pruning tool 110 is in the open position, the compression spring 120 is in a relaxed state. When the pruning tool 110 is in the closed position, the compression spring 120 is compressed, and has a tendency to push the two pruning tools 110 apart and move to the open position. When the two pruning tools 110 lose the human power, the two pruning tools 110 are bounced open by the compression spring 120, so as to facilitate the pruning operation again.

[0033] As a further embodiment, the first blades are provided on opposite sides of the two blade heads 112, and the first blades of the two blade heads 112 are arranged opposite to each other to form a scissor-like structure. In the closed position, the two first blades are staggered to cut branches. In the specific implementation process, the first blade can cut scions from target trees, or cut the ends of target trees to form fresh rootstock ends.

[0034] In some embodiments, see Figure 1A second blade 112a is provided on one side of the blade head 112 away from the first blade. The edge of the second blade 112a is crescent-shaped. The second blade 112a can be used to cut the end of the scion to form a wedge-shaped interface, thereby facilitating the subsequent grafting process. The second blade 112a can be integrated into the pruning shears 100, so that the relevant staff can carry one less knife, simplifying the pruning process.

[0035] In some embodiments, please refer to Figure 1 A finger ring 114 is provided on the shear handle 111, and the finger ring 114 is fixedly connected to the shear handle 111. The staff can hold the finger ring 114 with both hands to drive the two pruning tools 110 to move between the open position and the closed position. The finger ring 114 can facilitate the staff to grasp and apply force. The finger ring 114 is a flat oval or waist shape, and multiple fingers can be accommodated in the finger ring 114. As a further embodiment, the finger ring 114 is provided with anti-slip patterns, which are frosted patterns or cutting patterns. The anti-slip patterns can enhance the friction between the fingers and the finger ring 114, making it convenient for the staff to grasp.

[0036] In some embodiments, see Figure 2 and Figure 3 A clamping unit 130 is provided between the scissor handle 111 and the curved portion 113. The clamping unit 130 includes a plug connector 131 and a plug hole 132. The plug connector 131 is provided on the scissor handle 111, and the plug hole 132 is provided on the curved portion 113. The plug connector 131 is inserted into the plug hole 132. When necessary, the scissor handle 111 can be removed from the curved portion 113, so as to facilitate the sharpening of the cross-section knife 210.

[0037] In the specific implementation process, the plug connector 131 is positively deformed, and the plug hole 132 is adapted to the plug connector 131. The positively deformed structure can control the docking angle between the plug connector 131 and the plug hole 132, so that the cross-section knife 210 can accurately match the knife anvil 220. Preferably, screws can be used to fix the plug connector 131 and the curved portion 113 to prevent the shear handle 111 from falling off the curved portion 113.

[0038] In some embodiments, please refer to Figure 2 and Figure 3 The cross-cutting knife 210 is provided with a cross-cutting blade 211 on the side opposite to the knife anvil 220. The cross-cutting blade 211 can cut the rootstock from the radial direction of the rootstock so that the rootstock is normally opened to form a splicing seam. The cross-cutting knife 210 is provided with a longitudinal cutting blade 212 on the side relatively far from the cutter head 112. After the cross-cutting blade 211 splits the rootstock, if necessary, the longitudinal cutting blade 212 can also be used to cut the rootstock from the axial direction of the rootstock to expand the depth of the splicing seam and cooperate with the splicing of the scion.

[0039] Workflow: First, use the blade 112 of the pruning shears 100 to cut the scion, and cut the stock to obtain a fresh stock end face. Next, use the second blade 112a to cut the scion to form a wedge-shaped end. Then, insert the stock into the cross-section space, manually drive the two shear handles 111 to move closer to each other to the closed position, and the cross-section knife 210 cuts into the stock and passes through the stock to abut against the knife anvil 220, cross-sectioning the stock to obtain a splicing seam. Finally, insert the wedge-shaped end into the splicing seam and effectively seal it.

[0040] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
