Description

Technical Field

[0001] This utility model relates to the field of garden pruning device technology, and more specifically, to a handheld flower and grass pruning device. Background Technology

[0002] In garden art maintenance, regular pruning of flowers and plants is essential for promoting healthy growth. Proper pruning controls root and stem growth, balances nutrient distribution, and stimulates new shoot growth, contributing to a healthy shape and lushness. However, existing handheld pruning devices vary in size and specifications. While some pruning requires force, most existing pruning blades are either conventional designs with short handles and long blades, or larger devices with two large handles. These designs typically use straight blades subjected to cross-force to cut branches, requiring considerable force to hold or grip. Branches may slip during pruning, resulting in a poor user experience. Furthermore, existing devices often only have simple hinges for the blades, leaving them exposed. Careless placement and re-retrieval during pruning could cause cuts, posing a safety hazard. Therefore, this paper proposes a handheld flower and plant pruning device. Utility Model Content

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] See Figures 1 to 5 This utility model provides a handheld flower and plant trimming device, including an inner-locking blade body 11, a pressing blade body 42, and a connecting frame 14. The inner-locking blade body 11 and the pressing blade body 42 are hinged together by the connecting frame 14. The inner-locking blade body 11 is integrally formed with a first blade holder 1, and the pressing blade body 42 is integrally formed with a second blade holder 4. The inner-locking blade body 11 is designed with a blade structure having an inwardly concave arc groove. The outer cutting end of the inner-locking blade body 11 is a first cutting edge 12, and the edge of the first cutting edge 12 gradually slopes towards the pressing blade body 42 until it contacts the pressing blade body 42. The bottom of the pressing blade body 42 is a second cutting edge 43. The edge of the second blade 43 gradually tilts inward toward the inner blade body 11 until it contacts the inner blade body 11. One end of the connecting frame 14 is provided with a fixed end 15, a movable rope 16 is provided on the fixed end 15, a movable end 17 is provided on the movable rope 16, and a locking pin 18 is provided on the movable end 17. The inner blade body 11 is provided with a first locking hole, and the pressing blade body 42 is provided with a second locking hole. When the inner blade body 11 and the pressing blade body 42 are closed, the first locking hole is aligned with the second locking hole. The locking pin 18 is inserted into the first locking hole and the second locking hole, and the inner blade body 11 and the pressing blade body 42 enter the locked state.

[0026] When the pruning device is in the closed state, the locking pin 18 is inserted into the inner clamping blade 11 and the pressing blade 42 to keep them locked, preventing the pruning device from opening and closing automatically and posing a safety hazard, and preventing injury to the user. When the first blade holder 1 and the second blade holder 4 are subjected to opposite forces, a notch appears between the inner clamping blade 11 and the pressing blade 42, which can embed branches. When the first blade holder 1 and the second blade holder 4 move relative to each other under force, the inner clamping blade 11 and the pressing blade 42 move relative to each other, which can prune the branches placed in the inner arc groove. The concave arc design of the inner arc groove can stably restrict the branches within the groove, making it easier for the first blade 12 and the second blade 43 to move relative to each other to prune them, preventing the branches from shifting on the blades, and improving the stability of the pruning operation. Unlike the straight blade design of existing pruning devices, this solution restricts the branches, making the pruning operation more stable and providing a better user experience.

[0027] See Figure 3 and Figure 4 The locking post 18 has a locking notch on one end. In this embodiment, the fixing end 15 is set on the panel where the inner blade 11 is located. When the trimming device is not needed, the locking post 18 is inserted into the first locking hole and the second locking hole. The first blade holder 1 and the second blade holder 4 are supported by the strong spring 8 and are in a certain elastic support state during the locking period. This can drive the inner blade 11 and the pressing blade 42 to produce a certain degree of relative displacement. The locking notch is locked on the edge of the second locking hole, which can prevent displacement between the locking post 18 and the pressing blade 42 and establish the locking state of the trimming device. When trimming is needed, hold the first handle 2 and the second handle 5 until the first locking hole is aligned with the second locking hole, and take out the locking post 18. Then you can control the opening and closing of the inner blade 11 and the pressing blade 42.

[0028] Both ends of the first blade 12 are coated with titanium carbide, and both ends of the second blade 43 are coated with diamond-like carbon. This design uses the pressing blade 42 as the main pruning structure for branches, which cuts the branches through the second blade 43. The diamond-like carbon coating on the second blade 43 provides good lubricity and anti-adhesion, enhances its hardness and wear resistance, and improves the pruning efficiency and service life of the pressing blade 42 in branch pruning operations. The inner-cutting blade 11 is set as a limiting structure for branches and a supporting structure for the pressing blade 42. The first blade 12 assists the second blade 43 in cutting the branches. The titanium carbide coating on the first blade 12 provides good lubricity and wear resistance, improves the ease of contact between the first blade 12 and the second blade 43, and extends the service life of the first blade 12.

[0029] See Figure 2A first anti-detachment pad 13 is provided at the connection between the connecting frame 14 and the inner buckle blade 11, and a second anti-detachment pad 44 is provided at the connection between the connecting frame 14 and the pressing blade 42. The first anti-detachment pad 13 and the second anti-detachment pad 44 have the same structure and are symmetrically arranged about the connecting frame 14. The first anti-detachment pad 13 enhances the stability of the connection between the connecting frame 14 and the inner buckle blade 11, and the second anti-detachment pad 44 enhances the stability of the connection between the connecting frame 14 and the pressing blade 42, so as to avoid loosening or impact of the hinge end due to long-term use or corrosion.

[0030] See Figure 5 The second anti-detachment pad 44 includes a wear-resistant collar 444 that contacts the connecting frame 14. The outer radial end of the wear-resistant collar 444 is provided as a buffer limiting collar 443. The outer radial end of the buffer limiting collar 443 is provided with an inner nest 442. The inner nest 442 is provided with a rubber ring 441 on the pressing blade body 42. The wear-resistant collar 444 is made of the same metal structure as the connecting frame 14. Its contact with the connecting frame 14 will not affect the opening and closing state control of the trimming device. The buffer limiting collar 443 enhances the structural strength of the wear-resistant collar 444 and ensures the support stability of the connecting frame 14. The inner nest 442 establishes the contact between the second anti-detachment pad 44 and the pressing blade body 42, and works with the rubber ring 441 to enhance the hinge structure strength of the connecting frame 14. It also ensures that the trimming device needs to be subjected to a stable force to achieve opening and closing control, avoiding safety hazards caused by it being in a restricted state.

[0031] See Figure 1 The first blade holder 1 has a first handle 2 at one end, and a first rubber sleeve 3 on the first handle 2. The second blade holder 4 has a second handle 5 at one end, and a second rubber sleeve 6 on the second handle 5. The blade tip of this design occupies a shorter overall length of the trimming device. The first handle 2 and the second handle 5 greatly increase the length of the force application end, thereby reducing the output force of the trimming operation and reducing the trimming difficulty. The first rubber sleeve 3 and the second rubber sleeve 6 can prevent sweat or other corrosive liquids from contacting the first handle 2 and the second handle 5, and play a role in anti-slip operation during the trimming process. The tail ends of the first handle 2 and the second handle 5 are set at an angle, which effectively prevents them from slipping off the hand during use.

[0032] See Figure 3The inner blade body 11 is provided with a first wear-resistant end at the connection with the first blade holder 1. The first blade holder 1 is provided with a first anti-collision platform at the first wear-resistant end. The pressing blade body 42 is provided with a second wear-resistant end 41 at the connection with the second blade holder 4. The second blade holder 4 is provided with a second anti-collision platform at the second wear-resistant end 41. During the high-frequency reciprocating use of the trimming device, the first wear-resistant end and the second wear-resistant end 41 are in contact with each other. The two sets of contact surfaces are set as wear-resistant structures. On the basis of increasing the wear resistance of the two sets of contact surfaces, the friction generated by the two can generate a certain degree of frictional resistance during the use of the trimming device, which can effectively prevent the two sets of blades from swinging randomly. When the trimming device is in the closed state, the first anti-collision platform and the second anti-collision platform are almost vertically overlapping and aligned. That is, the first blade holder 1 and the second blade holder 4 are set in the same vertical space, saving production materials and storage space.

[0033] See Figure 1 and Figure 3 The first blade holder 1 is provided with a first abutment post 7 near the first handle 2, and the second blade holder 4 is provided with a second abutment post 9 near the second handle 5. A strong spring 8 is fitted on the first abutment post 7 and the second abutment post 9. When the first handle 2 and the second handle 5 are subjected to force and move to the set position, the first abutment post 7 and the second abutment post 9 come into contact with each other, so that the first handle 2 and the second handle 5 stay in a safe position, avoiding finger injury from pushing the handle with force. The strong spring 8 is set to assist the trimming device in a safe state of operation. The strong spring 8 can also cause the first blade holder 1 and the second blade holder 4 to be in a certain degree of interaction when they are in a static state, so that the locking notch of the locking post 18 and the second locking hole are in abutting state, keeping the first blade holder 1 and the second blade holder 4 in a locked state, avoiding the safety hazards caused by the blade being external.

[0034] Both the inner-fastening blade body 11 and the pressing blade body 42 are coated with an anti-adhesion coating, and a hydrophobic coating is sprayed on the anti-adhesion coating. The anti-adhesion coating can be a ceramic coating and / or a Teflon coating, which can enhance the sharpness and corrosion resistance of the inner-fastening blade body 11 surface, and has moisture-proof and rust-resistant properties. The hydrophobic coating can prevent moisture accumulation and effectively extend the service life of the inner-fastening blade body 11 and the pressing blade body 42.

[0035] The handheld flower and grass trimming device provided in this embodiment of the utility model has a first blade 12 set in the cutting area at the top of the inner blade body 11, and a second blade 43 set in the cutting contact end at the bottom of the pressing blade body 42. The blades outside the cutting contact end are not sharpened to reduce safety hazards. Locking pins 18 are designed on the two sets of blades to ensure the stability of their closed state and prevent the two sets of blades from spreading apart. The handle end is tilted and is equipped with a rubber sleeve to effectively prevent the trimming device from falling and causing safety hazards.

[0036] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
