Technical Field
[0001] This utility model relates to the field of landscaping technology, specifically a hedge trimmer for landscaping. Background Technology
[0002] Current hedge trimmers typically come with only a single-toothed blade. This design makes it difficult to balance pruning effectiveness and efficiency when dealing with branches of varying ages and tenderness. For example, while serrated blades can quickly cut through tender branches, they may cause unnecessary pulling on the branch, resulting in uneven cuts that hinder wound healing and subsequent growth. On the other hand, flat-toothed blades, due to insufficient cutting force, are prone to failing to cut through older branches or requiring repeated pruning, increasing the workload and time costs for gardeners. Utility Model Content
[0003] The purpose of this utility model is to provide a hedge trimmer for landscaping, which aims to flexibly select the appropriate tooth shape for pruning according to the maturity of different branches, so as to solve the problem that the existing hedge trimmers have poor pruning effect and low efficiency when dealing with branches of different materials.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A type of hedge trimmer for landscaping includes a first blade and a second blade, both of which are hinged to a pivot pin. A third blade is vertically disposed between the first and second blades and is fixedly connected to the pivot pin. The first blade has serrated edges, the second blade has straight teeth, and one end of the third blade has serrated teeth that match those of the first blade, while the other end has straight teeth that match those of the second blade.
[0006] Preferably, the tail of the third cutter head is provided with a sliding groove, and a sliding rod is slidably disposed in the sliding groove.
[0007] Preferably, the upper and lower ends of the slide rod are located outside the slide groove, and are respectively movably connected to the first cutter head and the second cutter head via a connecting rod.
[0008] Preferably, one end of the connecting rod is hinged to the upper and lower ends of the sliding rod.
[0009] Preferably, a second shaft pin is fixedly installed on the first and second cutter heads, and the other end of the connecting rod is hinged to the second shaft pin.
[0010] Preferably, both the first and second cutter heads are fixedly fitted with handles at their tails, and the handles are fitted with anti-slip sleeves.
[0011] Preferably, both the first and second cutter heads have rectangular teeth on their backs, with a tooth spacing of 5 mm.
[0012] Preferably, the saw teeth are V-shaped groove teeth, the angle of the V-shaped groove is 30°, and the distance between two adjacent saw teeth is 3mm.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This landscaping hedge trimmer is used to trim young branches. When pruning tender branches, the second blade can be slid to the third blade to engage with it. The sharpness of the straight teeth allows for quick cutting of the branches, reducing pulling on the branches and resulting in a smoother cut, which is beneficial for plant wound healing and subsequent growth. When pruning older branches, the first blade can be slid to the third blade to engage with it. Due to the stronger cutting force of the serrations, older branches can be easily cut off, avoiding situations where they cannot be cut or require repeated pruning. This significantly improves pruning efficiency and reduces the labor intensity and time cost for gardeners.
[0015] 2. The hedge trimmers used in this landscaping project have rectangular teeth on the back of the first and second blades. These teeth can be used to separate tangled branches when pruning hedges, making the branches more neat and orderly. This allows the blades to cut into the branches more smoothly, and untrimmed branches are less likely to be pulled or broken by the blades during pruning, thus reducing unnecessary damage.

[0021] 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.
[0022] Please see Figures 1-3 A type of hedge trimmer for landscaping includes a first blade 1 and a second blade 2, both of which are hinged to a pivot pin 5. A third blade 3 is vertically disposed between the first blade 1 and the second blade 2, and the third blade 3 is fixedly connected to the pivot pin 5. The first blade 1 has serrations 6 on its cutting edge, and the second blade 2 has straight teeth 8 on its cutting edge. One end of the third blade 3 has serrations 6 that are compatible with the first blade 1, and the other end has straight teeth 8 that are compatible with the second blade 2.
[0023] Among them, the pivot pin 5 serves as the hinge point between the cutter head 1 and the cutter head 2, allowing the cutter head 1 and the cutter head 2 to rotate flexibly during the trimming process and adapt to different trimming angles and positions.
[0024] The first blade 1 and the second blade 2 are respectively equipped with serrations 6 and straight teeth 8, which are responsible for different types of pruning tasks. Serrations 6 are suitable for cutting thicker or harder plant branches, while straight teeth 8 are suitable for fine pruning and trimming of tender branches. The combination of the two improves the comprehensiveness and efficiency of pruning.
[0025] The third blade (3) is fixedly connected to the first shaft pin (5), which serves to stabilize and connect the blades. Its two ends are respectively adapted to the first blade (1) and the second blade (2), allowing the hedge trimmer to select between coarse and fine trimming during operation, thus improving trimming efficiency.
[0026] Please see Figure 4 The tail of the cutter head 3 is provided with a groove 31, and a slide rod 11 is slidably provided in the groove 31.
[0027] Among them, the groove 31 is a slotted structure at the tail of the cutter head 3, which provides a sliding track for the slide rod 11, allowing the slide rod 11 to move freely in the groove 31, thereby realizing the flexible adjustment of the positions of the cutter head 1 and the cutter head 2, so as to adapt to different pruning tasks.
[0028] Please see Figure 4 The upper and lower ends of the slide rod 11 are located outside the slide groove 31, and are movably connected to the first cutter head 1 and the second cutter head 2 via the connecting rod 9.
[0029] Among them, the slide bar 11 is movably connected to the first cutter head 1 and the second cutter head 2 through the connecting rod 9, so that the first cutter head 1 and the second cutter head 2 can move synchronously with the slide bar 11, thereby realizing linkage pruning and improving the coordination and efficiency of pruning.
[0030] Link 9 provides additional support for cutter head 1 and cutter head 2, reducing the wobbling of the cutter head during the trimming process and improving the stability of the trimming.
[0031] Please see Figure 4 One end of the connecting rod 9 is hinged to the upper and lower ends of the sliding rod 11.
[0032] The connecting rod 9 is hinged to the upper and lower ends of the slide rod 11, allowing the connecting rod 9 to rotate flexibly under the drive of the slide rod 11, thereby adjusting the angle and position of the first cutter head 1 and the second cutter head 2 to adapt to different pruning needs.
[0033] Please see Figure 4 A shaft pin 10 is fixedly installed on the cutter head 1 and the cutter head 2, and the other end of the connecting rod 9 is hinged to the shaft pin 10.
[0034] Among them, the second shaft pin 10 is fixedly installed on the first cutter head 1 and the second cutter head 2, providing a stable connection point for the connecting rod 9 and ensuring that the connecting rod 9 can transmit motion efficiently;
[0035] The other end of the connecting rod 9 is hinged to the second shaft pin 10, so that the movement of the slide rod 11 can be transmitted to the first cutter head 1 and the second cutter head 2 through the connecting rod 9 to achieve linkage trimming. The hinged design allows the first cutter head 1 and the second cutter head 2 to rotate flexibly under the drive of the connecting rod 9, adapting to the trimming needs of different angles and positions.
[0036] Please see Figures 1-2 Both the first cutter head 1 and the second cutter head 2 have a handle 4 fixedly installed at their tails, and the handle 4 is fitted with an anti-slip sleeve 41.
[0037] Among them, the handle 4 is the part that the user directly holds. Its surface is covered with an anti-slip sleeve 41, which can effectively increase the friction when holding, prevent the hand from slipping, and improve the user's operating comfort and safety. At the same time, the anti-slip sleeve 41 can protect the handle 4 from wear and corrosion and extend the service life of the handle 4.
[0038] Anti-slip sleeves 41 are typically made of soft, hand-friendly materials, such as rubber, to reduce fatigue from prolonged use.
[0039] Please see Figure 3 Both the back of the blade head 1 and the blade head 2 are provided with rectangular teeth 7, and the tooth spacing of the rectangular teeth 7 is 5mm.
[0040] The design of the rectangular teeth 7 allows the first and second blades 1 and 2 to comb the branches more efficiently during the pruning process. Especially when dealing with dense or intertwined branches, the rectangular teeth 7 can separate and straighten the branches, thereby improving the combing efficiency.
[0041] The rectangular teeth 7 have a tooth spacing of 5mm. This uniform tooth spacing design allows the blade to maintain a stable rhythm when combing branches, reducing the phenomenon of blade jamming or slipping, reducing pruning resistance, and improving the smoothness of operation.
[0042] Please see Figure 3 The saw tooth 6 is a V-shaped groove tooth with an angle of 30° and a distance of 3mm between two adjacent saw teeth 6.
[0043] The V-groove design allows the saw teeth 6 to cut into branches more efficiently, especially when dealing with harder or thicker branches. The V-groove provides stronger cutting force, thereby improving pruning efficiency. It can also distribute the cutting force, reduce wear on the saw teeth 6 during the cutting process, extend the service life of the blade, and reduce maintenance and replacement costs.
[0044] The angle of the V-shaped groove is set to 30°, which allows the serration 6 to cut into and out of the branches more smoothly, reducing cutting resistance.
[0045] Working Principle: This landscaping hedge trimmer is designed for use in various applications. Before pruning, carefully observe the hedge branches to determine their age. Young branches are typically lighter in color and softer in texture, while older branches are darker in color and harder in texture. Select the appropriate tooth shape based on the branch's age. When pruning young branches, align the young branch with one end of the straight tooth 8 on the third blade (3), and grip the shears firmly, bringing the second blade (2) close to and working in conjunction with the third blade (3). Utilize the sharpness of the straight tooth 8 to quickly cut the branch, minimizing pulling on the branch. When pruning older branches, align the older branch with one end of the serration 6 on the third blade (3), and grip the shears firmly, bringing the first blade (1) close to and working in conjunction with the third blade (3). Utilize the cutting force of the serration 6 to easily cut the branch, avoiding repeated pruning. When branches are tangled and difficult to prune, use the rectangular teeth 7 on the back of the blade to first comb through the branches, arranging them neatly for easier subsequent pruning. This also reduces pulling and breakage on the branches, minimizing unnecessary damage.
