Abstract
Description
Technical Field
[0001] This application relates to the field of grafting technology, and more specifically, to a cleft grafting auxiliary tool. Background Technology
[0002] Tea grafting involves attaching a bud (scion) of a mother tree with superior traits to another plant (rootstock). Through the affinity and healing process of the cambium meristem cells of the scion and rootstock, a new plant is formed, altering the morphology and characteristics of the original plant. Grafting is the most effective way to renovate and transform low-yield tea gardens, characterized by early establishment and rapid results. It is also an important method for propagating tea varieties that are difficult to propagate through cuttings.
[0003] Currently, cleft grafting of tea trees mainly relies on manual operation. Workers use a knife to make a wedge-shaped incision on the rootstock to prepare the wedge-shaped surface of the scion, and then bind and fix it to complete the grafting. Although this method has long been used in agricultural production, it still has the following technical shortcomings:
[0004] The rootstock for tea grafting generally requires stems with a diameter of 0.5 to 3 cm. When using a knife, workers need to hold the rootstock with their other hand to ensure its stability. However, when using a knife to split, the knife is very easy to slide along the axis of the rootstock, causing cutting wounds, which makes this method of operation less safe. At the same time, it is not easy to exert force and save effort when splitting with a knife, making it difficult to control the cutting depth. Utility Model Content
[0005] The purpose of this application is to provide a chopping aid tool for splitting rootstock to form a wedge-shaped cut. It is easy to operate and use, has high operational safety, is unlikely to cause cutting injuries to workers, and can apply stable force during splitting to ensure that the cutting depth is easy to control and improve the accuracy of the cutting depth.

[0012] The cutting component is movably mounted on the upper cylinder.
[0013] In a preferred embodiment of this application, the sleeve further includes a connecting plate that connects the upper cylinder and the lower cylinder.
[0014] In a preferred embodiment of this application, the upper cylinder is provided with an observation window arranged in the vertical direction.
[0015] In a preferred embodiment of this application, the width of the observation window is set to one-tenth to one-sixth of the circumference of the cross-section of the upper cylinder.
[0016] In a preferred embodiment of this application, the sleeve is provided with a mounting block at the location of the clamping member, and the clamping member is mounted on the sleeve by mounting on the mounting block.
[0017] In a preferred embodiment of this application, the clamping member is a clamping pliers, the mounting block has a mounting protrusion, the mounting protrusion is provided with a connecting hole, and the pivot point of the clamping pliers is fixed to the connecting hole by a fastener.
[0018] In a preferred embodiment of this application, the driving component is a driving lever, which is disposed on the sleeve and drivenly connected to the cutting component.
[0019] In a preferred embodiment of this application, the driving lever includes a support rod and a driving rod. The support rod is disposed on the sleeve, the driving rod is rotatably connected to the support rod, and one end of the driving rod is connected to the cutting element.

[0034] See Figure 1 , Figure 1 This is a three-dimensional structural schematic diagram of the splitting auxiliary tool provided in the embodiments of this application.
[0035] The splicing assistance tool in this application includes:
[0036] Sleeve 10;
[0037] Clamping member 20 is movably disposed on sleeve 10 and communicates with the interior of sleeve 10;
[0038] The cutting assembly 30 includes a cutting element 31 and a driving element. The cutting element 31 is movably mounted on the sleeve 10. The driving element is connected to the cutting element 31 and is used to drive the cutting element 31 to move up and down.
[0039] In this embodiment, the sleeve 10 is used to be fitted onto the rootstock to be split. When operating, the worker puts the sleeve 10 onto the rootstock to be split from above. In this embodiment, the sleeve 10 is cylindrical. The size of the sleeve 10 can be set according to the plant to be grafted in actual work. For example, the plant to be grafted can be a tea tree.
[0040] It should be noted that in other embodiments, the sleeve 10 may also take other shapes. For example, the sleeve 10 may also take the shape of a square tube or other polygonal cylindrical structure. Here, we will not elaborate on the other shapes and structures that the sleeve 10 may take.
[0041] In this embodiment, the clamping member 20 is movably disposed on the sleeve 10 and communicates with the inside of the sleeve 10. Therefore, when the sleeve 10 is fitted onto the rootstock to be split, the worker can clamp the rootstock to be split in the sleeve 10 with the clamping member 20 to reduce the positional change of the rootstock to be split during splitting.
[0042] In this embodiment, before the worker puts the sleeve 10 on the rootstock to be split, the worker can use the drive to adjust the cutting member 31 to the position at the upper end of the sleeve 10, so that the sleeve 10 can be put on the rootstock to be split, and the cutting member 31 can cut the rootstock to be split better.
[0043] The cleft grafting auxiliary tool of this application embodiment is suitable for splitting rootstock to form a wedge-shaped cut, especially for splitting rootstock in tea tree grafting. When using this cleft grafting auxiliary tool, the sleeve 10 can be placed on the rootstock to be split, and the clamping member 20 provided on the sleeve 10 can be used to clamp the rootstock to be split in the sleeve 10. Then, the driving member of the cutting component 30 is operated to move the cutting member 31 downward to cut the rootstock to be split in the sleeve 10, thus completing the splitting of the rootstock. This cleft grafting auxiliary tool is easy to operate and use. The operator can operate the clamping member 20 with one hand and the cutting component 30 with the other hand to split the rootstock. It has high operational safety and is not likely to cause cutting injuries to the operator. Moreover, during splitting, since the cutting member 31 is driven by the driving member, the operator can easily and stably apply force during cutting, ensuring that the cutting depth is easy to control and improving the accuracy of the cutting depth.
[0044] See Figure 1 and Figure 2 In one embodiment, the sleeve 10 includes an upper cylinder 11 and a lower cylinder 12, with a clamping gap between the upper cylinder 11 and the lower cylinder 12. The clamping gap is used to set a clamping member 20, which is movably disposed between the upper cylinder 11 and the lower cylinder 12 through the clamping gap. The cutting member 31 is movably disposed on the upper cylinder 11.
[0045] By adopting the above-mentioned sleeve 10 structure, it is easy to set the clamping member 20 on the sleeve 10, and when the clamping member 20 clamps the rootstock to be split, it can clamp the middle part of the part of the rootstock to be split, thereby achieving a stable clamping effect.
[0046] In one embodiment, the sleeve 10 further includes a connecting plate 13, which connects the upper cylinder 11 and the lower cylinder 12. Specifically, the connecting plate 13 can be fixed by welding to connect the upper cylinder 11 and the lower cylinder 12. The connection plate 13 facilitates the connection between the upper cylinder 11 and the lower cylinder 12 and makes the structure of the sleeve 10 more stable.
[0047] In one embodiment, an observation window 111 is provided on the upper cylinder 11 in a vertical direction; specifically, the position of the observation window 111 on the upper cylinder 11 can correspond to the position of the side of the cutting member 31, and the height of the observation window 111 can be equivalent to the vertical movement distance of the cutting member 31, so that the cutting depth of the cutting member 31 on the rootstock to be split can be observed better.
[0048] Optionally, the width of the observation window 111 can be set to one-tenth to one-sixth of the circumference of the cross-section of the upper cylinder 11; preferably, the width of the observation window 111 can be set to one-eighth of the circumference of the cross-section of the upper cylinder 11; limiting the width of the observation window 111 facilitates observation of the cutting depth of the cutting piece 31 on the anvil to be split, and also facilitates the setting of the observation window 111 on the upper cylinder 11 and reduces production costs;
[0049] Alternatively, the observation window 111 may be a transparent observation window, which may be made of polycarbonate.
[0050] See Figure 1 and Figure 3 In one embodiment, the sleeve 10 is provided with a mounting block 14 at the location where the clamping member 20 is set, and the clamping member 20 is set on the sleeve 10 by being mounted on the mounting block 14.
[0051] Specifically, taking the above-mentioned sleeve 10, which includes an upper cylinder 11 and a lower cylinder 12, as an example, the sleeve 10 is provided with two mounting blocks 14 at the location of the clamping member 20. The two mounting blocks 14 are respectively located at the bottom end of the upper cylinder 11 and the top end of the lower cylinder 12. Optionally, the two mounting blocks 14 can be fixed to the upper cylinder 11 and the lower cylinder 12 by welding.
[0052] By setting the mounting block 14, it is easy to set the clamping member 20 on the sleeve 10 and to stabilize the structure of the sleeve 10 and the clamping member 20.
[0053] See Figure 1 , Figure 3 and Figure 4 In one embodiment, the clamping member 20 is a clamping pliers, and the mounting block 14 has a mounting protrusion 141, on which a connecting hole 1411 is provided. The pivot of the clamping pliers is fixed to the connecting hole 1411 by a fastener.
[0054] Specifically, the clamping teeth of the clamping pliers are vertically arranged; hexagonal bolts can be used as fasteners.
[0055] The clamping component 20 is a clamping pliers, which facilitates operation by workers and provides a good clamping effect. At the same time, it is also easy to set the clamping component 20 on the sleeve 10 without the need for other complex structures, making it easy to manufacture and produce.
[0056] See Figure 1 and Figure 3 In one embodiment, the driving member is a driving lever 32, which is disposed on the sleeve 10 and drivenly connected to the cutting member 31, so that the cutting member 31 can move up and down under the drive of the driving lever 32 to cut the anvil to be split.
[0057] Specifically, taking the above-mentioned sleeve 10, which includes an upper cylinder 11 and a lower cylinder 12, as an example, the drive lever 32 is disposed on the upper cylinder 11.
[0058] The drive unit adopts a drive lever 32 structure, which is easy for operators to operate and extremely easy to apply force and control the force, thereby better ensuring the cutting depth and improving the accuracy of the cutting depth.
[0059] In this embodiment, the drive lever 32 includes a support rod 321 and a drive rod 322. The support rod 321 is disposed on the sleeve 10, and the drive rod 322 is rotatably connected to the support rod 321. One end of the drive rod 322 is connected to the cutting member 31.
[0060] Specifically, when using it, the operator can apply force to the other end of the drive rod 322 to make the drive rod 322 rotate relative to the support rod 321, thereby causing one end of the drive rod 322 to move, which in turn causes the cutting piece 31 to move up and down to cut the anvil to be split.
[0061] The structure of this type of drive lever 32 is relatively simple, which makes it easy to set the drive lever 32 on the sleeve 10 and easy to operate, and can better achieve the effect of the cutting part 31 moving up and down.
[0062] In this embodiment, the cutting component 31 includes a connecting rod 311, a connecting block 312, and a cutting blade 313. One end of the connecting rod 311 is connected to one end of the drive rod 322, and the other end of the connecting rod 311 is connected to the connecting block 312. The cutting blade 313 is disposed on the connecting block 312. This structure of the cutting component 31 can cooperate well with the drive lever 32 to achieve the effect of vertical cutting.
[0063] Preferably, the cutting blade 313 is a high-carbon steel double-edged blade.
[0064] See Figure 1 and Figure 3 In one embodiment, the cutting element 31 is movably disposed on the inner wall of the sleeve 10, and the inner wall of the sleeve 10 is provided with a guide rail 112 that cooperates with the cutting element 31 to move up and down; the guide rail 112 can restrict and guide the movement position of the cutting element 31 when it moves up and down, so that the cutting element 31 can cut the rootstock to be split relatively stably.
[0065] In all the above embodiments, "large" and "small" are relative terms, "more" and "less" are relative terms, and "upper" and "lower" are relative terms. The embodiments of this application will not elaborate further on the expression of such relative terms.
