Description

Technical Field

[0001] This utility model belongs to the field of seedling technology, and specifically relates to a strawberry runner cutting propagation knife. Background Technology

[0002] Strawberry seedlings are primarily propagated through runner cuttings. This involves cutting the runners sprouting from the mother plant to separate cuttings with roots or growth points, a seedling knife is used. To avoid damage to the vascular bundles and growth points of the runners during cutting, the blade of the seedling knife must be made of a high-hardness alloy and finely polished to ensure high sharpness.

[0003] Although the blade of the seedling knife is highly sharp, the blade is completely exposed outside the handle. This means that when seedling workers handle the knife, the lack of effective protection of the blade makes it easy for them to be accidentally cut. Therefore, the seedling knife poses a certain safety hazard when not in use. Utility Model Content

[0004] To address the issue that seedling nursery workers are prone to cuts due to accidental contact with the blade during transport of the seedling knife, this utility model proposes a strawberry runner cutting seedling knife to overcome the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a strawberry runner cutting propagation knife, comprising a front handle and a rear handle, wherein a connecting component is provided between the front handle and the rear handle, a seedling knife is provided at the front end of the front handle, and an elastic storage component is provided inside the front handle, the elastic storage component being connected to the seedling knife, and a compression limiting component is provided inside the rear handle, the limiting end of the compression limiting component passing through the connecting component, and the limiting end being connected to the pushing end of the elastic storage component;

[0007] The elastic storage component is used to store the seedling knife, the connecting component is used to open the folded front handle and rear handle, the limiting end of the squeezing limiting component is used to pass through the front handle and rear handle, and at the same time the limiting end pushes the pushing end of the elastic storage component, so that the seedling knife moves out from the inside of the elastic storage component.

[0008] Furthermore, the connecting assembly includes connecting grooves, which are opened at the rear end of the front handle and the front end of the rear handle. The inner walls of the two connecting grooves are provided with rotating holes, and rotating rods are rotatably connected inside the rotating holes. Connecting plates are fixedly connected to the outer surfaces of the two rotating rods.

[0009] Furthermore, a positioning groove is provided on the inner wall of the connecting groove corresponding to the rotating hole, and a positioning block is movably connected inside the positioning groove. The positioning block is fixedly connected to the corresponding rotating rod.

[0010] Furthermore, the elastic storage component includes a storage cavity, which is opened inside the front handle. A pull plate is movably connected inside the storage cavity. A push rod is fixedly connected to one side of the pull plate. A storage spring is fixedly connected between one side of the pull plate and the inner wall of the storage cavity. The rear end of the seedling knife extends into the storage cavity, and the rear end of the seedling knife is fixedly connected to the other side of the pull plate.

[0011] Furthermore, the compression limiting assembly includes a rotating cavity, which is located inside the rear handle. A limiting groove is formed on the inner wall of the rotating cavity. The limiting groove passes through the rear handle and the connecting plate in sequence and extends into the storage cavity. The push rod is movably connected to the limiting groove, and a limiting rod is movably connected inside the limiting groove.

[0012] Furthermore, a threaded cylinder is rotatably connected to the rotating cavity, and a threaded block is threadedly connected inside the threaded cylinder. The threaded block is fixedly connected to the limiting rod. A control disc is rotatably connected to the rear end of the rear handle, and the control disc is fixedly connected to the threaded cylinder.

[0013] Furthermore, the front end of the seedling knife is arc-shaped, a V-shaped groove is provided at the blade of the seedling knife, a snap-fit ​​groove is provided at the top of the front handle, and a snap-fit ​​block is fixedly connected to the top of the rear handle corresponding to the snap-fit ​​groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model drives the compression limiting component, allowing the limiting end to move into the rear handle. At this point, since the limiting end no longer pushes the pushing end, the entire seedling knife automatically moves into the elastic storage component under the elastic force of the spring end. Simultaneously, the front and rear handles can be folded together. The above design makes it more convenient for seedling nursery workers to carry the seedling knife, and also reduces the risk of accidental cuts due to accidental contact with the seedling knife, thus improving safety.

[0016] 2. This utility model, by opening the front and rear handles, allows the control panel to rotate the threaded cylinder. The rotating cylinder, through a threaded block, pushes a limiting rod, which in turn pushes a pushing rod through a limiting groove. This push, in turn, pushes the seedling knife out of the storage cavity. This design allows the limiting rod to lock the two open handles with a simple rotation of the control panel, while simultaneously moving the seedling knife out of the storage cavity under the influence of the limiting rod. In summary, the movement of the limiting rod combines the actions of "locking" and "accessing" into one, making it more convenient for nursery workers to use the seedling knife.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0029] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0030] Please see Figures 1-7 As shown, this utility model is a strawberry runner cutting propagation knife, including a front handle 1 and a rear handle 2. A connecting component 3 is provided between the front handle 1 and the rear handle 2. A seedling knife 4 is provided at the front end of the front handle 1. An elastic storage component 5 is provided inside the front handle 1. The elastic storage component 5 is connected to the seedling knife 4. A compression limiting component 6 is provided inside the rear handle 2. The limiting end of the compression limiting component 6 passes through the connecting component 3, and the limiting end is connected to the pushing end of the elastic storage component 5.

[0031] The elastic storage component 5 is used to store the seedling knife 4. The connecting component 3 is used to open the folded front handle 1 and rear handle 2. The limiting end of the squeezing limiting component 6 is used to pass through the front handle 1 and rear handle 2. At the same time, the limiting end pushes the pushing end of the elastic storage component 5, and the seedling knife 4 moves out from the inside of the elastic storage component 5.

[0032] When the seedling knife 4 cuts the stolons, the rear handle 2 is rotated, causing it to rotate directly to the rear end of the front handle 1 under the drive of the connecting component 3. Then, the compression limiting component 6 is driven, allowing the limiting end to move out of the rear handle 2. At the same time, when the limiting end passes through the connecting component 3 and moves into the front handle 1, the limiting end pushes the pushing end of the elastic storage component 5, allowing the seedling knife 4 to move out of the elastic storage component 5.

[0033] By driving the compression limiting component 6, the limiting end can move into the interior of the rear handle 2. At this time, since the limiting end no longer pushes the pushing end, the entire seedling knife 4 automatically moves into the interior of the elastic storage component 5 under the elastic force of the spring end. At the same time, the front handle 1 and the rear handle 2 can be folded together. The above settings make it more convenient for seedling nursery workers to carry the seedling knife 4, and at the same time, it is less likely to cause scratches due to accidental contact with the seedling knife 4 during the carrying process, thereby improving safety.

[0034] In one embodiment, the connecting component 3 includes a connecting groove 301, which is provided at the rear end of the front handle 1 and the front end of the rear handle 2. The inner walls of the two connecting grooves 301 are provided with rotating holes 302. A rotating rod 303 is rotatably connected inside the rotating hole 302. A connecting plate 304 is fixedly connected to the outer surface of the two rotating rods 303.

[0035] By rotating the folded front handle 1 and rear handle 2, they can be opened. During this operation, the rotating rod 303 on the connecting plate 304 can rotate inside the corresponding rotating hole 302. The connecting plate 304 can connect the front handle 1 and rear handle 2 together through the rotating rod 303 and the rotating hole 302, so that they can always remain connected whether folded or open. The folded front handle 1 and rear handle 2 do not take up too much space, thus improving the convenience of carrying and transporting the seedling knife 4.

[0036] In one embodiment, for the connecting groove 301, the inner wall of the connecting groove 301 is provided with a positioning groove 305 corresponding to the rotating hole 302, and a positioning block 306 is movably connected inside the positioning groove 305. The positioning block 306 is fixedly connected to the corresponding rotating rod 303.

[0037] When the two handles are rotated, the two rotating rods 303 can drive the corresponding positioning blocks 306 to rotate inside the positioning grooves 305. When the positioning blocks 306 come into contact with the inner wall of the positioning grooves 305, the handles cannot rotate on the connecting plate 304. When the two handles are opened, if neither of the two handles can rotate on the connecting plate 304, it means that the two handles are level with each other. This setting facilitates the subsequent compression limiting assembly 6 to limit the two handles and the connecting plate 304.

[0038] In one embodiment, the elastic storage component 5 includes a storage cavity 501, which is located inside the front handle 1. A pull plate 502 is movably connected inside the storage cavity 501. A push rod 503 is fixedly connected to one side of the pull plate 502. A storage spring 504 is fixedly connected between one side of the pull plate 502 and the inner wall of the storage cavity 501. The rear end of the seedling knife 4 extends into the storage cavity 501, and the rear end of the seedling knife 4 is fixedly connected to the other side of the pull plate 502.

[0039] By pushing the push rod 503, the push rod 503 pulls the storage spring 504 via the pull plate 502 and moves inside the storage cavity 501. This causes the seedling knife 4 to move out of the storage cavity 501 under the action of the pull plate 502. When the pull plate 502 contacts the inner wall of the storage cavity 501, it means that the seedling knife 4 has completely moved out of the storage cavity 501. When the external force pushing the push rod 503 disappears, the storage spring 504 drives the pull plate 502 to reset. At the same time, the seedling knife 4 moves back into the storage cavity 501 under the action of the pull plate 502, so that the storage cavity 501 stores the seedling knife 4. In the above configuration, both the storage cavity 501 and the pull plate 502 are rectangular, which prevents the seedling knife 4 from rotating during use.

[0040] In one embodiment, the aforementioned compression limiting component 6 includes a rotating cavity 601, which is located inside the rear handle 2. A limiting groove 602 is formed on the inner wall of the rotating cavity 601. The limiting groove 602 passes through the rear handle 2 and the connecting plate 304 in sequence and extends into the storage cavity 501. The push rod 503 is movably connected to the limiting groove 602, and a limiting rod 603 is movably connected inside the limiting groove 602.

[0041] After opening the front handle 1 and the rear handle 2, the limiting rod 603 inside the rotating cavity 601 is pushed, so that the limiting rod 603 can move through the limiting groove 602 opened on the connecting plate 304 to the limiting groove 602 opened on the front handle 1. At this time, the limiting rod 603 can limit the opening of the front handle 1 and the rear handle 2, so that the two handles will not fold under the action of external force when they are held. After the limiting rod 603 comes into contact with the push rod 503, the limiting rod 603 continues to move, so that the limiting rod 603 can push the pull plate 502 and the seedling knife 4 inside the storage cavity 501 through the push rod 503.

[0042] In one embodiment, for the aforementioned rotating cavity 601, the rotating cavity 601 is rotatably connected to a threaded cylinder 604, the threaded cylinder 604 is internally threaded to a threaded block 605, the threaded block 605 is fixedly connected to a limiting rod 603, and the rear end of the rear handle 2 is rotatably connected to a control disc 606, the control disc 606 is fixedly connected to the threaded cylinder 604.

[0043] The threaded cylinder 604 is rotated by the control panel 606. Since both the limiting rod 603 and the limiting groove 602 are rectangular, the threaded block 605 does not rotate with the threaded cylinder 604. Instead, the limiting rod 603 moves under the push of the threaded cylinder 604, allowing the limiting rod 603 inside the threaded cylinder 604 to move out continuously. Because the threaded block 605 and the threaded cylinder 604 have a self-locking effect, the limiting rod 603 will not move arbitrarily inside the limiting groove 602 when it pushes the push rod 503 through the limiting groove 602.

[0044] In one embodiment, the seedling knife 4 has an arc-shaped front end, a V-shaped groove 7 at the blade, a snap-fit ​​groove 8 at the top of the front handle 1, and a snap-fit ​​block 9 fixedly connected to the top of the rear handle 2 corresponding to the snap-fit ​​groove 8.

[0045] When the stolon is cut with the seedling knife 4, the stolon can come into contact with the arc-shaped surface of the seedling knife 4, while the V-groove 7 limits the stolon. The above settings ensure that the stolon will not move randomly when it is cut, and the cut surface can form an inclined surface. The wound on the inclined surface allows more cells at the cut of the stolon to participate in the reaction, thereby improving the survival rate of the stolon. After the front handle 1 and the rear handle 2 are folded together, the locking block 9 can be locked into the inside of the locking groove 8, so that the folded front handle 1 and rear handle 2 will not separate randomly.

[0046] Through the above technical solution, 1. By driving the compression limiting component 6, the limiting end can move into the interior of the rear handle 2. At this time, since the limiting end no longer pushes the pushing end, the entire seedling knife 4 automatically moves into the interior of the elastic storage component 5 under the elastic force of the spring end. At the same time, the front handle 1 and the rear handle 2 can be folded together. The above setting makes it more convenient for seedling nursery workers to carry the seedling knife 4, and at the same time, it is less likely to cause scratches due to accidental contact with the seedling knife 4 during carrying, thereby improving safety; 2. By driving the front handle 1 and the rear handle 2, the limiting end can move into the interior of the rear handle 2. After handle 2 is opened, the threaded cylinder 604 is rotated via the control panel 606. The rotating threaded cylinder 604 pushes the limiting rod 603 through the threaded block 605, which in turn pushes the pushing rod 503 through the limiting groove 602. Under the push of the limiting rod 603, the pushing rod 503 can push the seedling knife 4 out of the storage cavity 501. This configuration allows the limiting rod 603 to lock the two open handles by simply rotating the control panel 606, while the seedling knife 4 moves out of the storage cavity 501 under the push of the limiting rod 603. In summary, the movement of the limiting rod 603 combines the "locking" and "accessing" actions into one, making it more convenient for nursery workers to use the seedling knife 4.
