Description

Technical Field

[0001] This utility model relates to the field of pruning devices, specifically a rose branch and leaf pruning device. Background Technology

[0002] Rose pruning devices are an important sub-category in the field of gardening tools. They primarily serve the needs of branch and leaf management during rose cultivation. They promote rose branching through scientific pruning, remove diseased and weak branches and overly dense branches after flowering to optimize nutrient distribution, and enhance ornamental value through shaping pruning.

[0003] However, the traditional pruning devices used in the current technology for pruning rose branches and leaves have some drawbacks: for the hard branches that are common in roses, the pruning process often requires the user to repeatedly apply a large amount of external force and squeeze the handle multiple times to gradually cut the branch, which can easily cause hand muscle fatigue due to repeated force and increase the user's physical exertion. Secondly, when using traditional pruning shears, if the pruning force is not properly controlled or the blade fails to cut the branch in one go, the branch is prone to springing back at the moment of breakage. During the springing process, thorny branches and leaves will bounce uncontrollably towards the hand or arm, and the sharp thorns can easily cut the skin, causing scratches, punctures and other hand injuries. Traditional pruning shears also lack the ability to collect the pruned branches and leaves. Utility Model Content

[0004] The purpose of this invention is to provide a rose pruning device to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A rose pruning device includes a first blade and a second blade. A shearing force-enhancing component is provided at one end of the first blade and the second blade. Serrations are provided on the upper surface of the second blade. A connecting piece is fixedly installed on one side of one end of the second blade. The upper end of the connecting piece is rotatably connected to one side of one end of the first blade. A fixing frame is fixedly installed on the side of the second blade near the connecting piece. A collecting component is provided at the lower end of the first blade and the second blade. A protective component is provided at the upper end of the shearing force-enhancing component.

[0006] Preferably, the shear force amplification component includes a housing, with the lower part of the inner wall of the housing fixedly installed on both sides of the fixed crank frame. A first gear is rotatably connected to the lower part of the inner wall of the housing, and a first ratchet is meshed with the outer side of the first gear. One end of the first ratchet is rotatably connected to a rotating handle, one end of the rotating handle is rotatably connected to the inner wall of the fixed crank frame, and one end of the rotating handle is fixedly connected to a second handle.

[0007] Preferably, a second gear is meshed with the outer side of the first gear, one side of the second gear is rotatably connected to one side of the inner wall of the outer casing, a third gear is meshed with the outer side of the second gear, one side of the third gear is rotatably connected to one side of the inner wall of the outer casing, a semi-circular ratchet is meshed with the outer side of the third gear, the semi-circular ratchet is fixedly installed on one side of one end of the first blade, a fixed crank is rotatably connected to one side of one end of the first blade, one side of the fixed crank is fixedly installed on the upper part of the inner wall of the outer casing, and one end of the fixed crank is fixedly connected to a first handle.

[0008] Preferably, a ratchet bar is provided between the teeth of the semi-circular ratchet, and a compression spring is fixedly installed at the lower end of the ratchet bar near the center. The lower end of the compression spring is fixedly installed at the upper end of the outer shell, and a fixing block is rotatably connected to one end of the ratchet bar. The lower end of the fixing block is fixedly connected to the upper end of the outer shell.

[0009] Preferably, the first handle and the second handle are externally fixedly fitted with anti-slip grips, and the first handle is a fixed connection structure, while the second handle is an up-and-down rotating connection structure.

[0010] Preferably, the collecting component includes magnetic suction holes, which are all located on the lower end of the outer shell near both sides. Magnetic suction blocks are magnetically engaged inside each of the two magnetic suction holes. A fixing rod is fixedly connected to the lower end of each of the two magnetic suction blocks. A collecting branch bag is fixedly installed at the lower end of each fixing rod, and the collecting branch bag is located below the first blade and the second blade.

[0011] Preferably, the protective component includes a magnetic slide rail, the lower end of which is fixedly mounted on the upper end of the housing, and a protective cover is slidably fitted inside the magnetic slide rail, with the inner wall of the protective cover covering one side of the first handle and the second handle.

[0012] The beneficial effects of this utility model are: 1. This utility model utilizes a shearing force amplification component and a three-stage meshing transmission of the first, second, and third gears. By leveraging the mechanical amplification characteristics of the gear ratio, the input force applied by the user to the second handle is amplified multiple times and transmitted to the semi-circular ratchet and the first blade. This provides sufficient hardness to the rose branch while allowing for shearing with relatively low operating force, reducing hand strain and shortening shearing and cleaning time. The ratchet bar, under the action of the compression spring, is always engaged in the gap between the teeth of the semi-circular ratchet, effectively limiting the reverse retraction of the first blade caused by the hardness of the rose branch. This prevents the blade from slipping or rebounding during shearing, ensuring that each applied force is converted into a continuous shearing action. This avoids the need for the user to squeeze the handle multiple times to gradually cut the branch, reducing hand muscle fatigue and physical exertion.

[0013] 2. This utility model, through the cooperation of magnetic holes and magnetic clips, allows the installation of the collection component to be completed without the aid of tools. It can be firmly snapped together by simply aligning and gently pushing. Disassembly is also possible by simply applying appropriate pulling force. Since the collection bag is located directly below the first and second blades, it can directly catch the branches that fall after being cut, preventing the branches from scattering into the equipment or the surrounding environment, thus realizing the real-time centralized collection of branches.

[0014] 3. This utility model slidably connects the lower end of the protective cover to the inside of the magnetic slide rail, making it easy to disassemble the protective cover. The protective cover can prevent hard branches from rebounding and injuring the hand, and it covers the back of the hand and the web of the thumb. The hand cover adopts an arc-shaped transparent plate structure. Attached Figure Description

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figure 1 and Figure 2 As shown, a rose pruning device includes a first blade 1 and a second blade 2. A shearing force amplification component 3 is provided at one end of the first blade 1 and the second blade 2. Saw teeth 21 are provided on the upper surface of the second blade 2. A connecting piece 22 is fixedly installed on one side of one end of the second blade 2. The upper end of the connecting piece 22 is rotatably connected to one side of one end of the first blade 1. A fixing frame 23 is fixedly installed on the side of the second blade 2 near the connecting piece 22. A collecting component 4 is provided at the lower end of the first blade 1 and the second blade 2. A protective component 5 is provided at the upper end of the shearing force amplification component 3.

[0019] In a specific embodiment, the connecting piece 22 is the key hinge point. The upper end of the connecting piece 22 of the second blade 2 is rotatably connected to the first blade 1 to form an opening and closing structure. The user applies force to the shearing force amplification component 3 by pressing and holding it. The cutting ends of the first blade 1 and the second blade 2 form a resistance arm, which is responsible for contacting and cutting the branches and leaves. The ratchet component of the shearing force amplification component 3 makes branches with a shearing force ≥150N only require a gripping force of 40N. It includes a three-stage planetary gear set with a transmission ratio of 1:3.5. The saw teeth 21 can first "clamp" the branches to avoid the branches from shifting during the cutting process. Combined with the "shearing force" when the flat blade of the first blade 1 closes, it achieves efficient branch cutting.

[0020] Please refer to Figures 1 to 3 , Figure 5As shown, as a technical optimization of this utility model, the shear force amplification component 3 includes a housing 31. The lower part of the inner wall of the housing 31 is fixedly installed on both sides of the fixed crank frame 23. A first gear 34 is rotatably connected to the lower part of the inner wall of the housing 31. A first ratchet 33 is meshed with the outer side of the first gear 34. One end of the first ratchet 33 is rotatably connected to a rotating handle 32. One end of the rotating handle 32 is rotatably connected to the inner wall of the fixed crank frame 23. A second handle 7 is fixedly connected to one end of the rotating handle 32. A second gear 35 is meshed with the outer side of the first gear 34. One side of gear 35 is rotatably connected to the inner wall of housing 31 near one side. The outer side of the second gear 35 is meshed with a third gear 36. One side of the third gear 36 is rotatably connected to the inner wall of housing 31 near one side. The outer side of the third gear 36 is meshed with a semi-circular ratchet 37. The semi-circular ratchet 37 is fixedly installed on one end of the first blade 1 near one side. One end of the first blade 1 is rotatably connected to a fixed crank 38 near the other side. One side of the fixed crank 38 is fixedly installed on the upper part of the inner wall of housing 31. One end of the fixed crank 38 is fixedly connected to a first handle 6.

[0021] Furthermore, a ratchet bar 310 is engaged between the teeth of the semi-circular ratchet 37. A compression spring 311 is fixedly installed at the lower end of the ratchet bar 310 near the center. The lower end of the compression spring 311 is fixedly installed at the upper end of the outer shell 31. A fixing block 39 is rotatably connected to one end of the ratchet bar 310. The lower end of the fixing block 39 is fixedly connected to the upper end of the outer shell 31. Anti-slip grips 8 are fixedly fitted on the outside of the first handle 6 and the second handle 7. The first handle 6 is a fixed connection structure, while the second handle 7 is a rotating connection structure.

[0022] In a specific embodiment, the first handle 6 is a fixed structure, which is indirectly fixed to the outer shell 31 and the first blade 1 through the fixed crank 38. During operation, it can serve as a "stable grip end". The second handle 7 is a rotating structure, one end of which is fixedly connected to the rotating handle 32. The other end of the rotating handle 32 is connected to the inner wall of the fixed crank frame 23 through a rotating joint. It can swing around the connection point as the second handle 7 rotates. Under the elastic force of the compression spring 311, the ratchet bar 310 is engaged in the tooth gap of the semi-circular ratchet 37. Since the semi-circular ratchet 37 is fixed to the first blade 1, the ratchet bar 310 can restrict the semi-circular ratchet 37 and the first blade 1 from rotating downward in the shearing direction. To prevent the blade from retracting due to external force or reaction force, the user holds the fixed first handle 6 for stability while simultaneously applying a downward and upward force to the second handle 7. This drives the second handle 7 to swing around the rotation point of the rotating rod 32 and the fixed crank 23. The second handle 7 drives the rotating rod 32 to rotate synchronously, and the first ratchet 33 at the other end of the rotating rod 32 swings accordingly. Since the first ratchet 33 is rotatably connected to the rotating rod 32, and the outer side of the first ratchet 33 meshes with the first gear 34, when the rotating rod 32 swings, the first ratchet 33 applies a "one-way driving force" to the first gear 34 through its teeth. When swinging upward, it does not drive the first gear 34 to rotate. The first gear 34 meshes with the second gear 35. When the first gear 34 rotates, it drives the second gear 35 to rotate synchronously. The second gear 35 is a "small gear". When the small gear drives the large gear, the torque will be amplified with the gear ratio, achieving the first force increase. The second gear 35 meshes with the third gear 36. Similarly, the second gear 35 continues to transmit the amplified torque to the third gear 36. The input force is further amplified through the second gear meshing. The semi-circular ratchet 37 is fixed to one end of the first blade 1. It swings synchronously with the rotation of the third gear 36. The swing of the semi-circular ratchet 37 will drive the first blade 1 to rotate around the fixed crank 38. During the "rotational shearing" process, if the first blade 1 tends to "reverse and retract" due to the material's reaction force, the semi-circular ratchet 37 will also tend to rotate in the opposite direction. At this time, the ratchet bar 310, under the elastic force of the compression spring 311, will be firmly locked in the tooth gap of the semi-circular ratchet 37, directly preventing the semi-circular ratchet 37 from reversing, thereby preventing the first blade 1 from retracting. After the rose branch is cut, by continuously swinging the second handle 7, the semi-circular ratchet 37 will continue to rotate until the teeth of the semi-circular ratchet 37 separate from the ratchet bar 310. Then, the ratchet bar 310 is manually swung upwards to restore the first blade 1 to its initial position. Figure 3 Shaped, the ratchet bar 310 is then held between the teeth of the semi-circular ratchet 37 by compression spring 311. This structure is suitable for branches with diameters of Φ3-15mm.

[0023] Please refer to Figure 1 and Figure 2 , Figure 4As shown, as a technical optimization of this utility model, the collecting component 4 includes magnetic suction holes 41. The magnetic suction holes 41 are all opened at the lower end of the outer shell 31 near both sides. The two magnetic suction holes 41 are magnetically attached to magnetic suction blocks 42. The lower ends of the two magnetic suction blocks 42 are fixedly connected to fixing bars 43. The lower ends of the fixing bars 43 are fixedly installed with collecting branch bags 44, and the collecting branch bags 44 are located below the first blade 1 and the second blade 2.

[0024] In a specific embodiment, the two magnetic suction blocks 42 are first aligned with the magnetic suction holes 41 on both sides of the lower end of the outer casing 31. The magnetic suction blocks 42 are pushed into the magnetic suction holes 41 by means of magnetic attraction until the magnetic suction blocks 42 and the magnetic suction holes 41 are completely and securely engaged. At this time, the fixing bar 43 connected to the magnetic suction blocks 42 will droop down, and the collection branch bag 44 fixed at the lower end of the fixing bar 43 will also be in place at the same time, and is directly below the first blade 1 and the second blade 2, completing the installation of the collection component 4. The cut branches will fall downward under the action of gravity and fall directly into the collection branch bag 44 below, realizing the real-time centralized collection of branches. The detachable collection branch bag is made of PE mesh cloth and has a volume of 15L.

[0025] Please refer to Figure 1 , Figure 4 As shown, as a technical optimization of this utility model, the protective component 5 includes a magnetic slide rail 52. The lower end of the magnetic slide rail 52 is fixedly installed on the upper end of the outer shell 31. A protective cover 51 is slidably sleeved inside the magnetic slide rail 52, and the inner wall of the protective cover 51 covers one side of the first handle 6 and the second handle 7.

[0026] In a specific embodiment, the lower end of the protective cover 51 is slidably connected to the magnetic slide rail 52, making it easy to disassemble the protective cover 51. The protective cover 51 can prevent hard branches from rebounding and injuring the hand, and the protective cover 51 covers the back of the hand and the web of the hand. The hand cover adopts an arc-shaped transparent plate structure.

[0027] In use, when the user prunes the rose branches, the second handle 7 has an up-and-down rotating structure. One end of the handle 7 is fixedly connected to the rotating rod 32, and the other end of the rotating rod 32 is connected to the inner wall of the fixed frame 23 through a rotating joint. It can swing around the connection point as the second handle 7 rotates. Under the elastic force of the compression spring 311, the ratchet bar 310 is engaged in the tooth gap of the semi-circular ratchet 37. Since the semi-circular ratchet 37 is fixed to the first blade 1, the ratchet bar 310 can restrict the semi-circular ratchet 37 and the first blade 1 from rotating downward in the shearing direction, preventing the blade from being damaged by external force or reaction force. To retract the lever, the user holds the fixed first handle 6 for stability while simultaneously applying a downward and upward force to the second handle 7. This drives the second handle 7 to swing around the rotation point of the rotating rod 32 and the fixed crank 23. The second handle 7 drives the rotating rod 32 to rotate synchronously, and the first ratchet 33 at the other end of the rotating rod 32 swings accordingly. The ratchet 33 is rotatably connected to the rotating rod 32, and its outer side meshes with the first gear 34. When the rotating rod 32 swings, the first ratchet 33 applies a "one-way driving force" to the first gear 34 through its teeth. When swinging upward, it does not drive the first gear 34 to rotate. The first gear 34 meshes with the second gear 35. When the first gear 34 rotates, it drives the second gear 35 to rotate synchronously. The second gear 35 is a "small gear" and a "large gear". When the small gear drives the large gear, the torque is amplified with the gear ratio, achieving the first force increase. The second gear 35 meshes with the third gear 36. Similarly, the second gear 35 continues to transmit the amplified torque to the third gear 36, further amplifying the input force through the second gear meshing. The semi-circular ratchet 37 is fixed to one end of the first blade 1 and swings synchronously with the rotation of the third gear 36. The swing of the semi-circular ratchet 37 will drive... The first blade 1 rotates and cuts around the connection point of the fixed curved rod 38, thereby pruning the rose branches. At this time, the fixed bar 43 connected to the magnetic card block 42 will hang down, and the collection bag 44 fixed at the lower end of the fixed bar 43 will also be in place at the same time, and is directly below the first blade 1 and the second blade 2, completing the installation of the collection component 4. The cut branches will fall downward under the action of gravity and fall directly into the collection bag 44 below, realizing the real-time centralized collection of branches. The protective cover 51 can prevent hard branches from rebounding and injuring the hands, and the protective cover 51 covers the back of the hand and the tiger's mouth.
