Description

Technical Field

[0001] This utility model relates to the field of agricultural tools, specifically to a convenient grafting tool for octagonal grafting. Background Technology

[0002] In the process of agricultural development, grafting technology has a long history as an important means of plant propagation and improvement. In the field of star anise cultivation, as the medicinal and economic value of star anise is continuously discovered, the scale of cultivation is gradually expanding, and the demand for star anise variety improvement and efficient propagation is becoming increasingly urgent. Grafting technology has become a key method to meet this demand, and the development of grafting tools, as the core tool for grafting operations, is crucial to promoting the progress of star anise grafting technology.

[0003] The existing technology still has the following drawbacks:

[0004] (1) The grafting tools used in the existing octagon grafting operations have a relatively traditional and simple overall structure design. The handle is usually a fixed structure, which makes the tools take up a lot of space during storage and carrying, and is not convenient to store.

[0005] (2) The operation of replacing the blade is relatively complicated. Operators need to use a variety of tools to complete the disassembly and installation of the blade. They need to first remove the screws or fasteners, remove the old blade, and then install the new blade and re-fix the screws or fasteners. The operation is quite cumbersome.

[0006] Therefore, we have made improvements and proposed a convenient grafting tool for octagonal grafting. Utility Model Content

[0007] The purpose of this utility model is to address the problem that the current knife handle is usually a fixed structure, which makes the knife take up a lot of space during storage and carrying, inconvenient to store, and complicated to replace the blade.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A convenient grafting tool for octagonal grafting is provided to improve the above-mentioned problems.

[0010] The specific details of this utility model are as follows:

[0011] Includes a base, and one side of the cutter is provided with a folding component for easy carrying and storage of the cutter by the operator. One side of the base is provided with a replacement component for quick replacement of the cutter head to facilitate octagonal grafting operations. One side of the folding component is provided with a fixing component for fixing the folding component to facilitate use by the operator.

[0012] The folding assembly includes a first handle and a second handle that are hinged to the base. The first handle and the second handle are symmetrically arranged. A limiting post is fixedly provided on the base. The limiting post passes through the base and is fixedly connected to the base. The limiting post is located between the first handle and the second handle.

[0013] As a preferred technical solution of this utility model, the replacement component includes a connecting block that is fixedly installed on the base. The connecting block is hollow, and a rectangular block is inserted into the other end of the connecting block. A blade is fixedly installed on the other end of the rectangular block. Two sets of telescopic locking posts are fixedly arranged on the rectangular block. The two sets of telescopic locking posts are symmetrically arranged, and a limit groove is opened on the connecting block corresponding to the two sets of telescopic locking posts.

[0014] As a preferred technical solution of this utility model, the fixing component includes a rotating column hinged to the end of the first tool holder, a screw fixedly installed at the other end of the rotating column, and a fixing member rotatably connected to the other end of the screw through a thread, and a groove is provided at one end of the second tool holder.

[0015] As a preferred technical solution of this utility model, the telescopic locking post has a cavity structure inside, and a spring and two sets of protrusions are provided inside the telescopic locking post. The two sets of protrusions are sleeved on both ends of the spring, and both sets of protrusions are in contact with the inner wall of the telescopic locking post. The telescopic locking post is made of rubber.

[0016] As a preferred technical solution of this utility model, the connecting block is provided with a horizontal column inside, which passes through two sets of telescopic locking columns and is fixedly connected to the inner side wall of the connecting block.

[0017] As a preferred technical solution of this utility model, the side walls of the first and second knife handles are provided with matching grooves, which match the shape of the blade.

[0018] As a preferred technical solution of this utility model, multiple sets of circular grooves are provided on both the first and second tool holders, and rubber rings are adhered to each of the multiple sets of circular grooves.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In the solution of this utility model:

[0021] 1. With the folding assembly, when in use, the operator unfolds the first and second handles around the hinge point. When the first and second handles are unfolded to a certain angle, the limiting post will contact the first and second handles and prevent them from unfolding further, thus fixing the handles stably in the unfolded position. At this time, the operator can use the tool to perform octagonal grafting operations by holding the first and second handles. At the same time, it is easy to fold and reduces the space occupied.

[0022] 2. With the set replacement component, when the blade needs to be replaced, the operator only needs to press the two sets of telescopic locking pins with their fingers at the same time, so that the telescopic locking pins disengage from the limiting groove on the connecting block and retract into the inside of the rectangular block. Then, gently pull the blade outward to pull the rectangular block out of the connecting block, thus completing the blade disassembly. The operator does not need to use complicated tools. With just simple pressing and inserting actions, the blade can be replaced in a short time. The operation is simple and easy to use. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1 As shown, this embodiment proposes a convenient grafting tool for star anise grafting, including a base 1, a folding component 2 for easy carrying and storage of the tool on one side of the tool, a replacement component 3 for quick replacement of the blade for star anise grafting operations on one side of the base 1, and a fixing component 4 for fixing the folding component 2 for easy use by the operator on one side of the folding component 2.

[0036] like Figure 2 As shown, the folding assembly 2 includes a first handle 201 and a second handle 202 hinged to the base 1. The first handle 201 and the second handle 202 are symmetrically arranged. A limiting post 203 is fixedly installed on the base 1, penetrating the base 1 and fixedly connected to it. The limiting post 203 is located between the first handle 201 and the second handle 202 to prevent the first handle 201 and the second handle 202 from being over-extended. In use, the operator unfolds the first handle 201 and the second handle 202 around the hinge point. When the first handle 201 and the second handle 202 are unfolded to a certain angle, the limiting post 203 contacts the first handle 201 and the second handle 202 and prevents them from unfolding further, thus stably fixing the handles in the unfolded position. At this time, the operator can use the tool to perform octagonal grafting operations by holding the first handle 201 and the second handle 202. At the same time, it is easy to fold and reduces the space occupied.

[0037] like Figure 3 and Figure 5As shown, the replacement component 3 includes a connecting block 301 fixedly installed on the base 1. The connecting block 301 is hollow, and a rectangular block 302 is inserted into the other end of the connecting block 301. A blade 303 is fixedly installed on the other end of the rectangular block 302. Two sets of telescopic locking posts 304 are fixedly provided on the rectangular block 302, and the two sets of telescopic locking posts 304 are symmetrically arranged. Limiting grooves are provided on the connecting block 301 corresponding to the two sets of telescopic locking posts 304. When it is necessary to replace the blade 303, the operator only needs to press the two sets of telescopic locking posts 304 simultaneously with their fingers to make the telescopic locking posts 304 disengage from the limiting grooves on the connecting block 301 and retract into the interior of the rectangular block 302. Then, the blade 303 is gently pulled outward, causing the rectangular block 302 to be pulled out of the connecting block 301, thus completing the disassembly of the blade 303. The operator does not need to use complicated tools; they can complete the replacement of the blade 303 in a short time with just simple pressing and inserting / pulling actions. The operation is simple and easy to use.

[0038] like Figure 3 and Figure 4 As shown, the fixing assembly 4 includes a rotating column 401 hinged to the end of the first handle 201. A screw 402 is fixedly installed at the other end of the rotating column 401, and a fixing member 403 is threadedly connected to the other end of the screw 402. A groove is provided at one end of the second handle 202. After use, the first handle 201 and the second handle 202 are folded around the hinge point, enclosing the blade 303 inside the first handle 201 and the second handle 202. At this time, the operator rotates the rotating column 401 around the hinge point at the end of the first handle 201 until the rotating column 401 drives the screw 402 to be located in the groove of the second handle 202. Then, the fixing member 403 is rotated until it fits tightly against the side wall of the second handle 202, thereby fixing the first handle 201 and the second handle 202 together and preventing the knife from accidentally unfolding during carrying or storage.

[0039] like Figure 5 and Figure 6As shown, the telescopic locking post 304 has an internal cavity structure. Inside the telescopic locking post 304 are a spring 5 and two sets of protrusions 6. The two sets of protrusions 6 are sleeved on both ends of the spring 5, and both sets of protrusions 6 are in contact with the inner wall of the telescopic locking post 304. The telescopic locking post 304 is made of rubber. When it is necessary to replace the blade 303, the operator presses the telescopic locking post 304 with their fingers. Because the telescopic locking post 304 is made of rubber, it has a certain degree of elasticity and a relatively soft texture. The force applied by the operator's fingers can be easily transmitted to the protrusions 6 inside the telescopic locking post 304. At this time, the spring 5 inside the telescopic locking post 304 will be compressed, and the two sets of protrusions 6 will slide accordingly, causing the rubber telescopic locking post 304 to contract and shorten in length, so that the telescopic locking post 304 is disengaged from the limiting groove on the connecting block 301. Then, the operator can easily pull the blade 303 outward to complete the disassembly of the blade 303.

[0040] like Figure 5 As shown, a horizontal post 7 is provided inside the connecting block 301. The horizontal post 7 passes through the two sets of telescopic locking posts 304 and is fixedly connected to the inner side wall of the connecting block 301. The horizontal post 7 can fix the two sets of telescopic locking posts 304 inside the connecting block 301, preventing the telescopic locking posts 304 from falling out of the connecting block 301.

[0041] like Figure 2 As shown, both the first handle 201 and the second handle 202 have fitting grooves on their side walls, which match the shape of the blade 303. These fitting grooves allow for a close fit to the contour of the blade 303, completely enclosing it within the first handle 201 and the second handle 202, thus protecting the blade 303.

[0042] like Figure 4 As shown, multiple sets of circular grooves 8 are provided on both the first handle 201 and the second handle 202, and rubber rings 9 are glued into each set of circular grooves 8. Since the human hand has certain curves and undulations in its natural state, when the operator holds the first handle 201 and the second handle 202 for grafting operations, different parts of the hand will naturally embed into the circular grooves 8, making them fit closely to the natural curve of the hand, facilitating the grafting operation. At the same time, the weight reduction of the first handle 201 and the second handle 202 through the multiple sets of circular grooves 8 also reduces the amount of solid material used in the handles, lowering costs.

[0043] Specifically, when using this portable octagonal grafting tool: (e.g.) Figure 2As shown, the operator unfolds the first handle 201 and the second handle 202 around the hinge point. When the first handle 201 and the second handle 202 are unfolded to a certain angle, the limiting post 203 will contact the first handle 201 and the second handle 202 and prevent them from unfolding further, thus stably fixing the handles in the unfolded position. At this time, the operator can use this tool to perform octagonal grafting operations by holding the first handle 201 and the second handle 202. At the same time, it is easy to fold, reducing the space occupied. Figure 3 and Figure 5 As shown, when the blade 303 needs to be replaced, the operator only needs to press both sets of telescopic locking posts 304 simultaneously with their fingers. Because the telescopic locking posts 304 are made of rubber, they have a certain degree of elasticity and are relatively soft. Figure 5 and Figure 6 As shown, the force applied by the operator's fingers can be easily transmitted to the protrusion 6 inside the telescopic locking post 304. At this time, the spring 5 inside the telescopic locking post 304 will be compressed, and the two sets of protrusions 6 will slide accordingly, causing the rubber telescopic locking post 304 to retract and shorten in length, so that the telescopic locking post 304 is disengaged from the limiting groove on the connecting block 301. After that, the operator can easily pull the blade 303 outward, causing the rectangular block 302 to be pulled out of the connecting block 301, thus completing the disassembly of the blade 303. The operator does not need to use complicated tools; they can complete the replacement of the blade 303 in a short time simply by pressing and inserting. The operation is simple and easy to use.

[0044] All technical features in this embodiment can be freely combined according to actual needs.

[0045] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
