Description

Technical Field

[0001] This utility model relates to the field of pruning tools, and in particular to a pruning tool for garden construction. Background Technology

[0002] Garden pruning tools have multiple uses: they can prune garden plants according to design requirements, shaping trees and shrubs into various forms such as spheres, squares, and cones to enhance the aesthetics and artistry of the landscape and meet the needs of different garden styles. By removing overgrown, inward-growing, and crossing branches, they guide plants to grow in specific directions, making the plants more neat and beautiful, preventing messy branch growth from affecting the landscape effect. Proper pruning can regulate the growth balance between the above-ground and underground parts of the plant, making the distribution of nutrients more reasonable. Pruning overly dense and weak branches allows more nutrients to be supplied to healthy branches, promoting the overall healthy growth of the plant. Appropriate shortening of some plants can stimulate the buds below the cut to sprout new branches.

[0003] However, existing technologies, such as Chinese Publication No. CN117441507, "A Pruner for Garden Construction," disclose a pruning tool for garden construction. This tool includes a collection hopper with a slot inside. Symmetrically arranged sliding grooves are located on both sides of the collection hopper, with sliding blocks slidably connected within each groove. A fixed shaft is fixedly connected to each sliding block. A threaded block is fixedly connected to the bottom of the collection hopper, and a lifting screw is threadedly connected within the threaded block. One end of the lifting screw is rotatably connected to a traction block located within the collection hopper. This invention first clamps the branches through the cooperation of a first rotating arm and a second rotating arm, and then suspends the device on the branches using a hook assembly, thereby reducing the physical exertion of workers. Furthermore, the collection hopper collects sawdust generated during sawing, preventing it from being scattered by the wind and improving the safety of the invention.

[0004] However, this device lacks a retractable handle. In garden construction, the height of branches to be pruned varies, and operators cannot easily reach branches of different heights for pruning without the aid of ladders or other auxiliary tools. They also cannot adjust the handle to the most suitable length, increasing fatigue and muscle tension. Furthermore, the device lacks a rotating crank for continuous pruning, resulting in the cumbersome process of manually opening and closing the traditional pruning shears for each cut. This prevents operators from pruning quickly and continuously, reducing work efficiency and increasing time and labor costs. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art. In garden construction, branches that need to be pruned vary in height, and operators cannot easily reach branches of different heights for pruning without the help of ladders or other auxiliary tools. They also cannot adjust the handle to the most suitable length, which increases fatigue and muscle tension. This leads to the cumbersome process of manually opening and closing traditional pruning shears for each cut, preventing operators from pruning quickly and continuously, reducing work efficiency, and increasing time and labor costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a garden pruning tool, comprising a shell, an extended shell movably embedded in the inner surface of the shell, two limiting strips fixedly connected to the outer surface of the extended shell, the outer surfaces of the two limiting strips movably embedded in the inner surface of the shell, a liner fixedly connected to the inner surface of the shell, a threaded rod rotatably connected inside the liner, an internal threaded block threadedly connected to the outer surface of the threaded rod, fixing plates fixedly connected to both sides of the internal threaded block, the side of the two fixing plates away from the internal threaded block fixedly connected to the inner surface of the extended shell, the outer surface of the threaded rod rotatably connected to the bottom of the shell, a knob fixedly connected to the bottom of the threaded rod, the inner surface of the knob rotatably connected to the outer surface of the shell, the knob drives the threaded rod to rotate inside the liner and the shell, the rotation of the threaded rod drives the internal threaded block, the internal threaded block is fixed to the inner surface of the extended shell by the fixing plates.

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.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a garden pruning tool, including a shell 1, an extended shell 2 movably embedded in the inner surface of the shell 1, two limiting strips 3 fixedly connected to the outer surface of the extended shell 2, the outer surfaces of the two limiting strips 3 movably embedded in the inner surface of the shell 1, a liner 4 fixedly connected to the inner surface of the shell 1, a threaded rod 5 rotatably connected inside the liner 4, an internal threaded block 6 threadedly connected to the outer surface of the threaded rod 5, fixing plates 7 fixedly connected to both sides of the internal threaded block 6, the side of the two fixing plates 7 away from the internal threaded block 6 fixedly connected to the inner surface of the extended shell 2, the outer surface of the threaded rod 5 rotatably connected to the bottom of the shell 1, a knob 8 fixedly connected to the bottom of the threaded rod 5, the inner surface of the knob 8 rotatably connected to the outer surface of the shell 1, the extended shell 2 can only move along the axial direction of the limiting strips 3, so rotating the threaded rod will cause the extended shell 2 to extend and retract along the axial direction of the limiting strips 3, thereby adjusting the length of the handle of the device.

[0026] like Figures 1 to 5 As shown, a fixing frame 9 is fixedly connected to the top of the outer shell 2. A U-shaped plate 10 is fixedly connected to one side of the inner side of the fixing frame 9. Two shafts 11 are fixedly connected to one side of the U-shaped plate 10. The ends of the two shafts 11 away from the U-shaped plate 10 are fixedly connected to the inner side of the fixing frame 9. The shafts 11 are fixed to the inner side of the fixing frame 9 through the U-shaped plate 10.

[0027] like Figures 1 to 5As shown, the outer surface of the shaft 11 is rotatably connected to the shear body 12, and the inner side of the shear body 12 is fixedly connected to the shear blade 13. The shear body 12 is provided with a force-bearing groove 14. The two shear bodies 12 swing in opposite directions around the shaft 11 as the axis and cut the plant branches and leaves through the shear blade 13.

[0028] like Figures 1 to 5 As shown, a power rod 15 is rotatably connected to one side of the fixed frame 9. A crank 16 is fixedly connected to one end of the power rod 15. A first force-applying rod 17 is fixedly connected to the side of the crank 16 away from the power rod 15. When the power rod 15 and the crank 16 rotate, the first force-applying rod 17 will make circular motion around the power rod 15 as the axis.

[0029] like Figures 1 to 5 As shown, a force-receiving groove block 18 is provided on the outer surface of the first force-applying rod 17, and a lifting rod 19 is fixedly connected to the top of the force-receiving groove block 18. When the first force-applying rod 17 moves inside the force-receiving groove block 18, it will drive the lifting rod 19 to reciprocate inside the stabilizing block 20.

[0030] like Figures 1 to 5 As shown, a stabilizing block 20 is movably sleeved on the outer surface of the lifting rod 19. One side of the stabilizing block 20 is fixedly connected to the inner surface of the fixed frame 9, and the lifting rod 19 can only move back and forth inside the stabilizing block 20.

[0031] like Figures 1 to 5 As shown, a sub-branch 21 is fixedly connected to the top of the lifting rod 19. Two second force-applying rods 22 are fixedly connected to the side of the sub-branch 21 near the scissor body 12. The outer surface of the second force-applying rods 22 is set inside the force-receiving groove 14. The reciprocating sub-branch 21 and the second force-applying rods 22 will drive the two scissor bodies 12 to swing in opposite directions around the axis of the shaft 11 under the action of the force-receiving groove 14.

[0032] like Figures 1 to 5 As shown, a mounting sleeve 23 is fixedly connected to one side of the outer surface of the mounting bracket 9. A motor 24 is fixedly embedded in the inner surface of the mounting sleeve 23. The output end of the motor 24 is fixedly connected to one end of the power rod 15. When the motor 24 is powered on, it will drive the power rod 15 and the crank 16 to rotate.

[0033] Working principle: First, adjust the length of the device handle according to the user's height and the required plant pruning height. Then, by turning knob 8, the threaded rod 5 rotates inside the liner 4 and housing 1. Rotating the threaded rod drives the internal threaded block 6, which is fixed to the inner surface of the outer housing 2 by the fixing plate 7. The outer housing 2 can only move along the axis of the limiting strip 3. Therefore, rotating the thread causes the outer housing 2 to extend and retract along the axis of the limiting strip 3, thus adjusting the length of the device handle. Next, start the external power supply to the motor 24. The motor 24 is fixed to one side of the fixing frame 9 by the mounting sleeve 23, and the shear body 12... The shear blade 13 is placed on the outside of the plant to be pruned. After the motor 24 is powered on, it will drive the power rod 15 and the crank 16 to rotate. The first force rod 17 will make a circular motion around the power rod 15 as the axis. When the first force rod 17 moves inside the force groove block 18, it will drive the lifting rod 19 to move back and forth inside the stabilizing block 20. At the same time, the reciprocating support 21 and the second force rod 22 will drive the two shear bodies 12 to swing in opposite directions around the shaft 11 as the axis under the action of the force groove 14, and cut the plant branches and leaves through the shear blade 13. The shaft 11 is fixed to the inside of the fixing frame 9 by the U-shaped plate 10.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
