Description

Technical Field

[0001] The utility model relates to the technical field of greening pruning, in particular to a greening pruning device. Background Art

[0002] In greening operations, pruning branches is a common maintenance task. When pruning thicker branches, traditional pruning knives often fail to firmly fix the branches at the root of the knife, resulting in displacement or sliding of the branches during the pruning process. This not only affects the pruning efficiency, but may also pose a threat to the safety of the operators. Therefore, it is of great practical significance to develop a pruning knife that can effectively fix the branches and prevent displacement and sliding. Utility Model Content

[0003] The purpose of the utility model is to provide a greening pruning device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a greening pruning device, comprising an upper clamping shear, a latching tooth structure and a lower clamping shear, the upper clamping shear is penetrated by a shaft bolt, the upper clamping shear and the lower clamping shear are movably connected by the shaft bolt, a blade on one side of the upper clamping shear is provided with a latching tooth structure, the latching tooth structure is designed with a plurality of semicircular openings, and the diameters of the semicircular openings are arranged from large to small from the intersection of the upper clamping shear and the lower clamping shear, and branches can be clamped through the semicircular openings. Since the semicircular openings in the latching tooth structure are arranged from large to small, branches of different diameters can be clamped, and the closer to the intersection of the upper clamping shear and the lower clamping shear, the thicker branches can be clamped, and the lever principle is used to save effort when pruning thicker branches, and a handle is provided at one end of the upper clamping shear and the lower clamping shear, and the outer side of the handle is covered with an anti-slip sleeve, and the outer side of the anti-slip sleeve is provided with anti-slip patterns.

[0005] The upper and lower clamps are made of conventional carbide materials to ensure that they have high hardness and wear resistance, and can maintain sharpness and bite effects for a long time. When using the device to prune garden seedlings, the front of the upper clamp is smooth in design, which makes it faster to prune large quantities of tree branches. The semicircular design of the tooth structure enables the tooth structure to penetrate deep into the surface of the branch when pruning thicker branches. Through the bite action, the branch can be firmly fixed to prevent it from shifting and sliding, thereby improving pruning efficiency and operation safety. Moreover, the closer to the intersection of the upper and lower clamps, the thicker the branches that can be clamped. Through the principle of leverage, it can save more effort. The front of the device is smooth, and the rear uses a tooth structure in combination, which can enable staff to prune quickly and directly, reduce damage to the surface of the branch, ensure pruning quality, and make the pruned branches more beautiful.

[0006] Preferably, a blade is provided on one side of the lower shearing clip and the upper shearing clip.

[0007] The blades on one side of the lower shear and the upper shear can ensure that the device is sharp so as to cut the saplings.

[0008] Preferably, the upper shear clip and the lower shear clip are of curved design.

[0009] Because the upper shears and the lower shears are designed to be curved, it is convenient for workers to prune branches so that the upper shears and the lower shears can better fit the surface of the leaves, making it easier for workers to use.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] When pruning branches, the utility model can penetrate into the surface of the branch through the latching tooth structure, and can firmly fix the branch through the biting action to prevent the branch from displacement and sliding, thereby improving pruning efficiency and operation safety, and the branch that is closer to the intersection of the upper clamping shear and the lower clamping shear is thicker, and more labor can be saved through the lever principle. The front part of the device is smooth, and the rear part adopts the latching tooth structure, which can enable the staff to prune quickly and directly, reduce the damage to the surface of the branch, ensure the pruning quality, and make the pruned branch more beautiful.

However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.

[0017] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0018] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.

[0019] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0020] Although terms such as "first", "second", and "third" may be used herein to describe various components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, component, region, layer, or portion from another component, component, region, layer, or portion.

[0027] Embodiment 1

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model proposes a greening pruning device, including an upper clamping shear 1, a locking tooth structure 2 and a lower clamping shear 3, the upper clamping shear 1 is penetrated by a shaft bolt 4, the upper clamping shear 1 and the lower clamping shear 3 are movably connected by the shaft bolt 4, a blade on one side of the upper clamping shear 1 is provided with a locking tooth structure 2, one end of the upper clamping shear 1 and the lower clamping shear 3 is provided with a handle 5, the outside of the handle 5 is covered with an anti-slip cover 501, and the outside of the anti-slip cover 501 is provided with anti-slip patterns.

[0029] The working principle of the greening pruning device based on Example 1 is: the upper clamp 1 and the lower clamp 3 are made of conventional carbide materials to ensure that they have high hardness and wear resistance, and can maintain sharpness and bite effect for a long time. When using the device to prune garden seedlings, the front of the upper clamp 1 is smooth in design, which is faster when pruning large quantities of tree branches. The semicircular design of the tooth structure 2 enables the tooth structure 2 to penetrate into the surface of the branch when pruning thicker branches. Through the bite action, the branch can be firmly fixed to prevent its displacement and sliding, thereby improving the pruning efficiency and operation safety. Moreover, the closer to the intersection of the upper clamp 1 and the lower clamp 3, the thicker the branch can be clamped. Through the lever principle, it can save more effort. The front of the device is smooth, and the rear uses a combination of the tooth structure 2, which can enable the staff to be quick and direct in the pruning process, can reduce damage to the surface of the branch, ensure the pruning quality, and make the pruned branches more beautiful.

[0032] In this embodiment, Figure 1 As shown, branches can be clamped through the semicircular openings. Since the semicircular openings in the clamping tooth structure 2 are arranged from large to small, branches with different diameters can be clamped, and the closer to the intersection of the upper clamping shear 1 and the lower clamping shear 3, the thicker branches can be clamped. Through the lever principle, it is easier to save effort when pruning thicker branches; as shown in FIG. Figure 1 As shown, the blades on one side of the lower shear 3 and the upper shear 1 can ensure the sharpness of the device so as to cut the saplings; Figure 2 As shown, since the upper clip 1 and the lower clip 3 are designed to be curved, it is convenient for workers to prune branches so that the upper clip 1 and the lower clip 3 can better fit on the surface of the leaves, making it easier for workers to use.

[0033] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
