Description

Technical Field

[0001] This utility model belongs to the field of garden machinery and equipment technology, specifically relating to a garden pruning tool. Background Technology

[0002] The manual high-branch saw is one of the most basic and commonly used aerial pruning tools in garden maintenance. It is widely used for tree shaping, thinning, and removing dead branches, such as... Figure 1 As shown, it typically consists of a saw blade, an extension rod, and a connector between the saw blade and the extension rod. Some models of manual high-pole saws also have an auxiliary hook integrally formed at the head and / or tail of the saw blade, which can be used to hook branches. This manual high-pole saw relies on manual pulling to prune high-altitude branches and is suitable for pruning branches with smaller diameters. It has the advantage of being inexpensive.

[0003] When using existing manual high-pole saws, the saw blade is pulled vertically by manpower to cut the branches, or the branches are hooked off using an auxiliary hook. However, for branches at the upper and lower edges of the trunk, the trunk itself cannot be used to cut them off by pulling or hooking them off, which is a limitation of the use of existing manual high-pole saws. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model proposes a garden pruning tool that combines a saw blade, a shovel, and a chopping knife on the basis of a manual high-branch saw. In garden maintenance, it can be used for high-altitude pruning of tree branches extending in multiple directions by combining sawing, shoveling, and chopping, making its functions more comprehensive.

[0005] This utility model is achieved through the following technical solution: A garden pruning tool includes a manual high-branch saw blade. A shovel is located on the back of the saw teeth at the head of the blade, used for vertically shoveling branches. The shovel extends in the same direction as the length of the saw blade. A chopping tool is located on the side wall of the saw blade head, used for horizontally cutting branches. The saw blade is connected to an extension rod via a connector for high-altitude pruning of tree branches. Workers can use the saw blade to cut branches vertically by pulling it, or to shovel branches with the shovel. Workers can also use the chopping tool to cut branches at the upper and lower edges of the trunk horizontally. In garden maintenance, this tool allows for high-altitude pruning of branches extending in multiple directions using a combination of sawing, shoveling, and chopping, improving the efficiency of tree pruning.

[0006] Furthermore, both the machete and the shovel are welded onto the saw blade, allowing for modification and processing of existing manual high-branch saws.

[0007] Furthermore, a connecting plate is provided on the back of the saw teeth at the head of the saw blade. The connecting plate has a slot for inserting and engaging with the saw blade. The connecting plate and the saw blade are detachably connected by multiple bolts. The chopper and the shovel are both welded to the connecting plate. The chopper and the shovel can be disassembled and assembled simultaneously by disassembling and assembling the connecting plate, which facilitates the maintenance of the chopper and the shovel.

[0008] Furthermore, ribs are welded between the two blades of the machete and the sides of the connecting plate, which increases the structural strength of the machete.

[0009] Furthermore, the shovel has four sides, one of which is welded to the connecting plate, and the other three sides are provided with blades. Workers can use the shovel to vertically cut branches by pulling vertically, or they can use the blades on the side of the shovel to cut branches on the front and back sides of the trunk horizontally.

[0010] Furthermore, it also includes an extension rod and a connector. The end of the saw blade is detachably connected to the extension rod via the connector. The extension rod is a telescopic rod structure with adjustable length, which can adjust the length of the extension rod according to the working height requirements, thereby controlling the working height of the saw blade, shovel, and machete.

[0011] Furthermore, it also includes a short handle, which replaces the extension rod and is detachably connected to the tail of the saw blade via a connector. When the saw blade is used with the short handle, the trimming tool can be used for low-altitude operations.

[0012] As can be seen from the above technical solution, the garden pruning tool provided by this utility model has the following beneficial effects: This pruning tool can be used for high-altitude pruning of tree branches in garden maintenance. The end of the saw blade is connected to an extension rod via a connector to form a manual high-branch saw. Based on the manual high-branch saw, this pruning tool combines a saw blade, a shovel, and a chopping knife. Workers can use the saw blade to cut branches by pulling the extension rod vertically, or use the shovel to cut branches vertically. Workers can also move the extension rod horizontally to drive the saw blade and chopping knife, and use the chopping knife to cut branches at the upper and lower edges of the branches horizontally. Workers can use this pruning tool in garden maintenance to perform high-altitude pruning operations on tree branches extending in multiple directions by combining sawing, shoveling, and chopping, which can improve the efficiency of tree branch pruning. This pruning tool has more comprehensive functions than existing manual high-branch saws. Attached Figure Description

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] In the description of this application, it should be understood that the terms "upper", "lower", "top", "bottom", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0024] Example 1 A garden pruning tool, which relates to a manual high-branch saw, such as Figures 2 to 6 As shown, it mainly consists of a saw blade 1, an extension rod 2, a connector 3, an auxiliary hook 4, a chopping knife 5, a shovel 6, a connecting plate 7, and a rib plate 8.

[0025] The saw blade 1, extension rod 2, and connector 3 are the conventional structure of existing manual high-pole saws. The connector 3 is installed at the tail of the saw blade 1 by bolts or rivets, that is... Figure 1 The bottom of the saw blade 1 shown is detachably connected to the joint 3 by bolts, with the extension rod 2 being connected to the joint 3. like Figure 2 and Figure 6 As shown, the head of the saw blade 1 is integrally formed with an auxiliary hook 4, which can be used to hook branches; like Figure 6 As shown, the extension rod 2 is a telescopic rod structure with adjustable length. Specifically, the extension rod 2 is composed of multiple rod sections assembled together, with adjacent rod sections connected by threads. The overall length of the extension rod 2 can be adjusted according to the number of rod sections used to assemble the extension rod 2, and the length of the extension rod 2 can be adjusted according to the working height requirements to control the working height of the saw blade 1, the shovel 6, and the chopping knife 5.

[0026] like Figure 2 and Figure 3 As shown, the connecting plate 7 has a slot for the back of the saw teeth at the head of the saw blade 1 to be engaged. The connecting plate 7 and the saw blade 1 are detachably connected by multiple bolts. Specifically, the auxiliary hook 4 is part of the head structure of the saw blade 1, as shown... Figure 4 As shown, the connecting plate 7 is installed on the back of the curved part of the saw blade 1 head, and part of the auxiliary hook 4 is also inserted into the slot of the connecting plate 7. The machete 5 is welded to one side of the connecting plate 7, such as... Figures 2 to 4 As shown, the saw blade 1 extends vertically with its teeth facing right. When the chopper 5 is installed on the head of the saw blade 1 along with the connecting plate 7, the chopper 5 is horizontally positioned and perpendicular to the saw blade 1, and the cutting edge of the chopper 5 faces right. The shovel 6 is welded to the connecting plate 7 on the side opposite to the slot, such as Figures 2 to 4 As shown, the saw blade 1 extends vertically with its teeth facing to the right. When the shovel 6 is installed on the top of the saw blade 1 along with the connecting plate 7, the shovel 6 is parallel to the saw blade 1 and the cutting edge of the shovel 6 faces upward. The chopper 5 and the shovel 6 can be disassembled and assembled simultaneously by disassembling and assembling the connecting plate 7, which facilitates the maintenance of the chopper 5 and the shovel 6. In addition, the chopper 5 and the shovel 6 can also be fixed to the saw blade 1 by welding, which can be modified and processed on the existing manual high branch saw. However, compared with the detachable connection structure between the connecting plate 7 and the saw blade 1, the method of welding the chopper 5 and the shovel 6 to the saw blade 1 is not convenient for disassembly and assembly.

[0027] In this embodiment, to improve the structural strength of the machete 5, ribs 8 are welded between the two blade surfaces of the machete 5 and the sides of the connecting plate 7, such as... Figures 2 to 4 As shown, the saw blade 1 extends vertically with its teeth facing to the right. Ribs 8 are welded between the upper side of the chopper 5 and the side of the connecting plate 7, as well as between its lower side and the side of the connecting plate 7.

[0028] In this embodiment, to enhance the functionality of the shovel 6, the shovel 6 has four sides, one side of which is welded to the connecting plate (7), and the other three sides are provided with cutting edges, such as... Figure 4 and Figure 5 As shown, the top edge of the shovel 6 has a blade, and the blades on its left and right sides are not shown. Workers can use the shovel 6 to vertically cut branches by pulling it vertically, or they can use the shovel 6 to cut branches on the front and back sides of the branch in the horizontal direction.

[0029] The materials of the saw blade 1, machete 5, shovel 6, and connecting plate 7 mentioned above are all conventional materials used in existing cutting tools, and will not be described in detail here.

[0030] The working principle of this pruning tool for high-altitude pruning of tree branches in garden maintenance is as follows: The tail of the saw blade 1 is connected to the extension rod 2 via a connector 3, forming a manual high-branch saw. The worker can hold the end of the extension rod 2 furthest from the saw blade 1 and raise the saw blade 1 to a high position to prune tree branches. The worker can place the saw blade 1 on the branch to be pruned and pull the extension rod 2 vertically to drive the saw blade 1, thus cutting the branch. This is the same as the existing manual high-branch saw. The worker can also pull the extension rod 2 vertically to drive the scraper 6, using the scraper 6 to vertically cut branches extending laterally along the trunk or branches on the sides before and after the main trunk branches. Furthermore, the worker... The extension rod 2 can also be moved laterally to drive the saw blade 1 and the chopping knife 5. The chopping knife 5 can be used to horizontally cut the branches at the upper and lower edges of the tree trunk (these branches are difficult to cut with the saw blade 1 due to the obstruction of the branches). During the manual operation of this pruning tool, the worker can make routine adjustments to the position of the saw blade 1, the chopping knife 5 and the shovel 6 by rotating the extension rod 2, and select which blade to use. The worker can use this pruning tool to perform high-altitude pruning operations that combine sawing, shoveling and chopping on branches extending in multiple directions on trees in garden maintenance, which can improve the efficiency of tree branch pruning.

[0031] Example 2 A garden pruning tool, differing from Example 1 in that: Figure 7 As shown, the manual high-branch saw also includes a short handle 9. Based on the detachable connection structure of the extension rod 2 and the connector 3 described in Embodiment 1, after the extension rod 2 is disassembled, the short handle 9 replaces the extension rod 2 and is detachably connected to the tail of the saw blade 1 through the connector 3. When the saw blade 1 is used with the short handle 9, the pruning tool can be used for low-altitude operations. The above-mentioned high-altitude operations and low-altitude operations are two relative concepts, and there is no specific boundary between them. The height at which the saw blade 1 is used with the short handle 9 to allow workers to prune branches is the low-altitude operation height, which will not be elaborated here.
