Description

Technical Field

[0001] This utility model relates to the field of grafting tool technology, and in particular to a multifunctional grafting tool. Background Technology

[0002] Grafting tools are horticultural tools specifically designed for plant grafting. Their core function is to precisely cut the scion and rootstock so that their cambium layers fit together tightly, thereby promoting healing and growth, and achieving variety improvement or plant propagation. They are usually made of high-carbon steel or stainless steel, balancing durability and sharpness.

[0003] As indicated by announcement number CN210017044U, this utility model relates to the field of fruit tree cultivation tools, specifically a multifunctional grape grafting knife. It includes a box body with an internal cavity. Slides are provided on the upper and lower right sides and the upper left side of the cavity. Several arc-shaped locking blocks are symmetrically arranged inside the slides. A multifunctional knife is positioned between the right slides and connected to the slides via a fixing device. Scissors are located on the lower side of the left slide. This utility model, by providing both cutting and planing blades, eliminates the hassle of constantly changing the knife, making grafting operations faster. The addition of scissors enhances the knife's functionality. The fixing device allows for the extension and retraction of the multifunctional knife, protecting it and preventing accidental injury when not in use. The inclusion of a polishing stone allows for friction on the multifunctional knife, improving its cutting and planing capabilities.

[0004] In existing technologies, a fixing device can be installed to extend and retract the multi-functional knife, protecting it and preventing accidental injury to personnel when the grafting knife is not in use. However, the fixing device extends and retracts by pressing and pushing. When the knife is stored, if it is subjected to external collision or pressure, the buckle / locking mechanism of the fixing device may be displaced or deformed, leading to fixing failure. This can cause the blade to extend or loosen unexpectedly, potentially injuring the operator or damaging the blade itself, seriously affecting the safety and service life of the tool. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the existing technology, the locking mechanism of the fixing device is easily displaced or deformed when the tool is stored and subjected to external collision or pressure, which leads to fixing failure. This causes the blade to extend or loosen unexpectedly, which may not only cut the operator, but also damage the blade itself, seriously affecting the safety and service life of the tool.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional grafting knife, comprising a handle body, a protective component provided at one end of the handle body, a slot provided on the side of the handle body near the protective component, a limiting component provided inside the slot, the protective component comprising a protective plate, an outlet slot provided in the middle of the protective plate, deflection baffles rotatably connected to both sides of the protective plate at the outlet slot, and a rotating shaft fixedly connected to the top and bottom of the deflection baffles, the rotating shafts being rotatably connected to the protective plate.

[0007] In a preferred embodiment, an extrusion plate is slidably connected inside the rotating shaft, and a limiting block is fixedly connected in a ring array to the outer wall of the extrusion plate. The limiting block is slidably connected to the rotating shaft, and a rotating rod is fixedly connected to the top of the extrusion plate. The rotating rod rotates through the rotating shaft and the protective plate. A spring is provided at the top of the rotating shaft outside the rotating rod, and the spring abuts against the extrusion plate. A limiting rotating block is fixedly connected to the top of the rotating rod, and the limiting rotating block is engaged with the top of the protective plate.

[0008] In a preferred embodiment, the limiting component includes a limiting rotating plate, which is slidably connected inside the slot. A connecting rod is fixedly connected to the middle of the limiting rotating plate, and the connecting rod passes through the limiting rotating plate.

[0009] In a preferred embodiment, the connecting rod is rotatably connected to a connecting plate at one end, and positioning rods are fixedly connected to both ends of the connecting plate on the side away from the connecting rod. The positioning rods slide through the main body of the tool holder and are located inside the slot.

[0010] In a preferred embodiment, a positioning groove is provided inside the main body of the knife handle on the side near the corresponding slot. The positioning groove is engaged with the positioning rod. Sliding grooves are provided at the top and bottom of the main body of the knife handle. A lead screw and a limiting rod are provided inside the sliding groove. The lead screw rotates through one side of the main body of the knife handle, and the limiting rod is fixed inside the sliding groove.

[0011] In a preferred embodiment, a rotating head is fixedly connected to one end of the lead screw located outside the main body of the tool holder. The rotating head is rotatably connected to the main body of the tool holder. A slider is slidably connected inside the slide groove. A blade is fixedly connected to one side of the slider that is close to the other. The blade is slidably connected inside the main body of the tool holder. A positioning hole is provided in the middle of the blade near the rotating head. The positioning hole is engaged with a positioning rod. A connecting ring is fixedly connected to the bottom end of the tool holder located at the rotating head.

[0012] The beneficial effects of this utility model are as follows: In this invention, when the cutting tool is needed, pulling the limiting block upward causes the rotating rod to rise, which in turn causes the extrusion plate to rise. The rising extrusion plate extrudes the spring, at which point the limiting block separates from the protective plate. Subsequently, the limiting block rotates 180 degrees, causing the rotating rod to rotate, which in turn causes the extrusion plate to rotate, which in turn causes the limiting block to rotate, which in turn causes the rotating shaft to rotate. This causes the rotating shaft to rotate the deflection baffle 180 degrees, at which point the deflection baffles unfold, allowing the blade to be removed from the outlet groove. During use, the unfolded deflection baffles can press against the user's fingers, thus protecting the fingers and preventing branches from piercing the user's fingers during cutting. When the deflection baffles are closed, they can block the blade outlet, preventing the blade from accidentally slipping out and causing injury to the user. Before the blade is removed, take out the limiting rotating plate and the positioning rod. After the blade is removed, pass the positioning rod through the slot and the positioning hole into the positioning groove and engage it. At this time, both the limiting rotating plate and the connecting plate are in the slot. Then rotate the connecting rod, which drives the limiting rotating plate to rotate. The limiting rotating plate rotates 90 degrees in the slot, so that the limiting rotating plate is engaged inside the slot, thereby further limiting the blade and improving the stability of the blade.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a multifunctional grafting knife, including a handle body 1, a protective component at one end of the handle body 1, a slot 11 on the side of the handle body 1 near the protective component, a limit component inside the slot 11, the protective component including a protective plate 21, an outlet slot 22 in the middle of the protective plate 21, deflection baffles 23 rotatably connected to both sides of the protective plate 21 at the outlet slot 22, and a rotating shaft 24 fixedly connected to the top and bottom of the deflection baffles 23, the rotating shaft 24 and the protective plate 21 Rotary connection, the inside of the rotating shaft 24 is slidably connected to the extrusion plate 25, the outer wall of the extrusion plate 25 is fixedly connected to the limit block 251 in an annular array, the limit block 251 is slidably connected to the rotating shaft 24, the top of the extrusion plate 25 is fixedly connected to the rotating rod 27, the rotating rod 27 rotates through the rotating shaft 24 and the protective plate 21, the top of the rotating shaft 24 is provided with a spring 26 located outside the rotating rod 27, the spring 26 abuts against the extrusion plate 25, the top of the rotating rod 27 is fixedly connected to the limit block 28, the limit block 28 is snapped into the top of the protective plate 21.

[0017] In this embodiment, when the cutting tool is needed, the limiting rotating block 28 is pulled upward to drive the rotating rod 27 to rise. The rotating rod 27 drives the pressing plate 25 to rise, and the pressing plate 25 presses the spring 26. At this time, the limiting rotating block 28 separates from the protective plate 21. Then, the limiting rotating block 28 rotates 180 degrees, which drives the rotating rod 27 to rotate. The rotating rod 27 drives the pressing plate 25 to rotate, and the pressing plate 25 drives the limiting block 251 to rotate. The limiting block 251 drives the rotating shaft 24 to rotate, so that the rotating shaft 24 drives the deflection baffle 23 to rotate 180 degrees. At this time, the deflection baffle 23 unfolds, allowing the blade 17 to be moved out from the outlet groove 22. When in use, the unfolded deflection baffle 23 can press against the fingers of the personnel, thereby protecting the fingers and preventing the branches from piercing the fingers of the personnel during slippage. When the deflection baffle 23 is closed, it can block the outlet of the blade 17, preventing the blade 17 from accidentally slipping out and causing injury to the personnel.

[0018] like Figure 2As shown, the limiting assembly includes a limiting rotating plate 31, which is slidably connected inside the slot 11. A connecting rod 32 is fixedly connected to the middle of the limiting rotating plate 31. The connecting rod 32 passes through the limiting rotating plate 31. A connecting plate 33 is rotatably connected to one end of the connecting rod 32. Positioning rods 34 are fixedly connected to both ends of the connecting plate 33 on the side away from the connecting rod 32. The positioning rods 34 slide through the tool holder body 1 inside the slot 11.

[0019] In this embodiment, before the blade 17 is removed, the limiting rotating plate 31 and the positioning rod 34 are taken out. After the blade 17 is removed, the positioning rod 34 is passed through the slot 11 and the positioning hole 171 and inserted into the positioning groove 12 for engagement. At this time, the limiting rotating plate 31 and the connecting plate 33 are both inserted into the slot 11. Then, the connecting rod 32 is rotated, and the connecting rod 32 drives the limiting rotating plate 31 to rotate. The limiting rotating plate 31 rotates ninety degrees in the slot 11, so that the limiting rotating plate 31 is engaged inside the slot 11, thereby further limiting the blade 17 and improving the stability of the blade 17.

[0020] like Figure 1 - Figure 3 As shown, a positioning groove 12 is provided inside the main body 1 of the knife handle, near the side corresponding to the slot 11. The positioning groove 12 is engaged with the positioning rod 34. Sliding grooves 13 are provided at the top and bottom of the main body 1 of the knife handle. A lead screw 14 and a limiting rod 15 are provided inside the sliding groove 13. The lead screw 14 rotates through one side of the main body 1 of the knife handle. The limiting rod 15 is fixed inside the sliding groove 13. A rotating head 18 is fixedly connected to the end of the lead screw 14 located outside the main body 1 of the knife handle. The rotating head 18 is rotatably connected to the main body 1 of the knife handle. A slider 16 is slidably connected inside the sliding groove 13. A blade 17 is fixedly connected to the side of the slider 16 that is close to each other. The blade 17 is slidably connected inside the main body 1 of the knife handle. A positioning hole 171 is provided in the middle of the blade 17 near the end of the rotating head 18. The positioning hole 171 is engaged with the positioning rod 34. A connecting ring 19 is fixedly connected to the bottom end of the main body 1 of the knife handle located at the rotating head 18.

[0021] In this embodiment, rotating the rotating head 18 drives the slide groove 13 to rotate, the slide groove 13 drives one slider 16 to slide, the slider 16 drives the blade 17 to slide, and the other slider 16 plays a limiting support role. The blade 17 gradually moves out, and the blade 17 is further limited by the positioning rod 34. During use, the operator can use the telescopic connecting ring 19 to connect, thereby avoiding the accidental detachment of the handle body 1 when the operator is working in the air, which would require the operator to climb up and down again, resulting in reduced work efficiency.

[0022] Working principle: First, when the tool is needed, pull the limiting rotating block 28 upward to drive the rotating rod 27 to rise. The rotating rod 27 drives the extrusion plate 25 to rise, and the extrusion plate 25 extrudes the spring 26. At this time, the limiting rotating block 28 separates from the protective plate 21. Then, the limiting rotating block 28 rotates 180 degrees, driving the rotating rod 27 to rotate. The rotating rod 27 drives the extrusion plate 25 to rotate, and the extrusion plate 25 drives the limiting block 251 to rotate. The limiting block 251 drives the rotating shaft 24 to rotate, causing the rotating shaft 24 to drive the deflection baffle 23 to rotate 180 degrees. At this time, the deflection baffles 23 unfold. Then, the limiting rotating plate 31 and the positioning rod 34 are removed. Next, rotate the rotating head 18 to drive the slide groove 13 to rotate. The slide groove 13 drives one slider 16 to slide, and the slider 16 drives the blade 17 to slide. The other slider... Block 16 acts as a limiting support. The blade 17 is gradually moved out, and then the positioning rod 34 passes through the slot 11 and the positioning hole 171 and enters the positioning groove 12 for engagement. At this time, the limiting rotating plate 31 and the connecting plate 33 are both in the slot 11. Then, the connecting rod 32 is rotated, which drives the limiting rotating plate 31 to rotate. The limiting rotating plate 31 rotates 90 degrees in the slot 11, so that the limiting rotating plate 31 is engaged inside the slot 11, thereby further limiting the blade 17 and improving the stability of the blade 17. When in use, the unfolded deflection baffle 23 can press against the fingers of the personnel, thereby protecting the fingers and preventing the branches from piercing the fingers of the personnel when slipping. When the deflection baffle 23 is closed, it can block the exit of the blade 17, preventing the blade 17 from accidentally slipping out and causing injury to the personnel.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
