Description

Technical Field

[0001] This utility model relates to the field of garden craft equipment technology, and more specifically, to an adjustable-height garden pruning shears. Background Technology

[0002] A garden is a specially cultivated natural environment and recreational area. It is a beautiful natural environment and recreational area created by using engineering technology and artistic means in a certain area, such as modifying the terrain (or further building mountains, stacking rocks, and managing water), planting trees and flowers, constructing buildings, and arranging garden paths. Modern lifestyles and living environments have urgent functional and artistic requirements for gardens. After the trees in the garden grow to a certain extent, their branches need to be pruned, which requires the use of pruning shears.

[0003] In actual use, traditional scissor locks are usually located on the outside of the handle. When adjusting the length of the scissors to cut plants of different heights, the handle lock may accidentally collide with the plant, causing the lock to loosen and affecting the safety of using the scissors. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable height garden pruning shears to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable-height garden pruning shears includes two shear heads. A positioning shaft is rotatably connected to the inner side of each shear head. A serrated edge is formed on one side of each shear head. A connecting plate is fixedly connected to one side of each shear head. A second connecting plate is located on the outer side of the first connecting plate. A telescopic mechanism is provided on one side of the second connecting plate. The telescopic mechanism includes a handle. One side of the handle is fixedly connected to the outer side of the second connecting plate. The second handle is slidably connected to the inner side of the handle. Two positioning strips are fixedly connected to the outer side of the second handle, and the outer sides of the positioning strips are slidably connected to the inner side of the handle. A grip is fixedly connected to one end of the second handle, and a pressure block is slidably connected to the inner side of the second handle. An adjustment mechanism is provided on the inner sides of the first and second connecting plates.

[0007] By adopting the above technical solution, the serrations on the outside of the shear head can be used to cut plants that are inconvenient to prune, thus improving the effectiveness of the shears.

[0008] As a further description of the above technical solution: a limiting shaft is fixedly connected to the inner side of the second tool holder, and a transmission rod is rotatably connected to the outer side of the limiting shaft. Multiple locking holes are opened on the inner side of the first tool holder. An outer cylinder is fixedly connected to the inner side of the second tool holder, and a spring is fixedly connected to the inner side of the outer cylinder. An insert block is fixedly connected to the top of the spring. The outer side of the insert block is slidably connected to the inner side of the outer cylinder. The end of the insert block penetrates through the inner side of the second tool holder and engages with the inner side of the multiple locking holes. A pusher is hinged to the outer side of the insert block. The outer side of the pusher is slidably connected to the inner side of the outer cylinder. One end of the pusher is slidably connected to the inner side of the transmission rod. A spring is fixedly connected to one end of the transmission rod, and one end of the spring is fixedly connected to the inner side of the second tool holder.

[0009] By adopting the above technical solution: the push of the pressure block allows the transmission rod to lift and push the insert block through the push frame, so that the positioning mechanism of tool holder one and tool holder two can be used on the inside of tool holder one and tool holder two, avoiding accidental collision or snagging that could cause loosening.

[0010] As a further description of the above technical solution: the adjustment mechanism includes two bolts, the outer side of the bolts is slidably connected to the inner side of the connecting plate two, the end of the bolts is fixedly connected to a throttle handle, the inner side of the connecting plate one has multiple threaded holes, the inner side of the threaded holes is threadedly connected to the bottom end of the bolts, and the connecting plate one and the connecting plate two are rotatably connected to a positioning shaft two.

[0011] By adopting the above technical solution, the angles of the scissor head and handle can be adjusted according to the actual usage of the operator by utilizing the deflection of connecting plate two and connecting plate one, thereby optimizing the lever-saving principle and improving the operating effect.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a telescopic mechanism, compared with the existing technology, the deflection transmission of the built-in transmission rod is used to protect the locking and unlocking of the extension and retraction of the second tool handle from the first tool handle. This makes the locking of the first and second tool handles less likely to be loosened by accidental collisions or snags, making the extension and retraction locking more secure and the operation safer.

[0014] 2. By setting an adjustment mechanism, compared with the existing technology, the positioning angle of the scissor head and the handles of the first and second blades can be adjusted by using the deflection positioning of the second connecting plate and the first connecting plate. This allows the user to adjust to the most labor-saving and comfortable cutting angle according to their own physical condition, optimizes the lever-saving principle, finds the best balance between ease of operation and cutting force, and improves the control effect.

[0023] 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.

[0024] The embodiments disclosed in this application are as follows: Figures 1-7The adjustable-height garden pruning shears shown include two shear heads 1. A positioning shaft 3 is rotatably connected to the inner side of each shear head 1. A serration 2 is provided on one side of each shear head 1. A connecting plate 4 is fixedly connected to one side of each shear head 1. A connecting plate 6 is provided on the outer side of the connecting plate 4. A telescopic mechanism is provided on one side of the connecting plate 6. The telescopic mechanism includes a handle 7. One side of the handle 7 is fixedly connected to the outer side of the connecting plate 6. A handle 8 is slidably connected to the inner side of the handle 7. Two positioning strips 9 are fixedly connected to the outer side of the handle 8. The outer side of the positioning strips 9 is slidably connected to the inner side of the handle 7. A handle 10 is fixedly connected to one end of the handle 8. A pressure block 19 is slidably connected to the inner side of the handle 8. An adjustment mechanism is provided on the inner side of the connecting plate 4 and the connecting plate 6. The serration 2 on one side of each shear head 1 can be used to cut plants that are inconvenient to prune, and the rotation of the two shear heads 1 outside the positioning shaft 3 can be used to cut the plants.

[0025] Reference Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, a limiting shaft 11 is fixedly connected to the inner side of the tool holder 2 8, and a transmission rod 17 is rotatably connected to the outer side of the limiting shaft 11. Multiple locking holes 12 are provided on the inner side of the tool holder 1 7. An outer cylinder 13 is fixedly connected to the inner side of the tool holder 2 8, and a spring 14 is fixedly connected to the inner side of the outer cylinder 13. A plug 15 is fixedly connected to the top of the spring 14. The outer side of the plug 15 is slidably connected to the inner side of the outer cylinder 13. The end of the plug 15 penetrates the inner side of the tool holder 2 8 and engages with the inner side of the multiple locking holes 12. A pusher 16 is hinged to the outer side of the plug 15, and the outer side of the pusher 16 is slidably connected to the inner side of the outer cylinder 13. One end of the pusher 16 is connected to the transmission rod 17. The inner side of the moving rod 17 is slidably connected, and one end of the transmission rod 17 is fixedly connected to a spring 18. One end of the spring 18 is fixedly connected to the inner side of the handle 8. By pressing the pressure block 19, the transmission rod 17 can be pushed and deflected, thereby squeezing and contracting the spring 18 and the first spring 14, so that the insert block 15 can be separated from the locking hole 12 on the inner side of the handle 7. Then the extension length of the handle 7 and the second handle 8 can be adjusted. The internal design of the handles 7 and the second handle 8 can effectively prevent the connection between the handles 7 and the second handle 8 from colliding and loosening, thus maintaining the safety of using the scissors.

[0026] Reference Figure 1 , Figure 3 and Figure 5As shown, the adjustment mechanism includes two bolts 20. The outer side of the bolts 20 is slidably connected to the inner side of the connecting plate 2 6. The end of the bolts 20 is fixedly connected to a handle 21. Multiple threaded holes 22 are opened on the inner side of the connecting plate 1 4. The inner side of the threaded holes 22 is threadedly connected to the bottom end of the bolts 20. A positioning shaft 2 5 is rotatably connected between the connecting plate 1 4 and the connecting plate 2 6. The two bolts 20 are used to position the connecting plate 2 6 and the connecting plate 1 4, so that the positioning angle of the handle 1 7 and the scissor head 1 can be adjusted. The operator can adjust the handle 1 7 and the handle 2 8 to apply more suitable pressure to the scissor head 1.

[0027] The working principle of this utility model is as follows: When pruning plants of different heights in a garden, the worker first presses the two pressure blocks 19 on the inner side of the two handles 2 8, causing the pressure blocks 19 to push the transmission rod 17 to deflect on the inner side of the handle 2 8 with the limiting shaft 11 as the fulcrum. At the same time, the transmission rod 17 compresses and contracts the spring 2 18. Simultaneously, the transmission rod 17 drives the pusher 16 on the other side to push the insert block 15, causing the pusher 16 to slide and rise and fall on the inner side of the outer cylinder 13. At the same time, the insert block 15 compresses and contracts the spring 14, causing the insert block 15 to move inward towards the inner side of the handle 2 8, thereby separating the insert block 15 from the corresponding locking hole 12 on the inner side of the handle 1 7. Then, the handle 2 8 is pulled out from the inner side of the handle 1 7. After the handle 2 8 and the handle 1 7 have extended to the appropriate length, the pressure on the pressure blocks 19 is released. Then, the spring 2 18 and the spring 14 respectively compress and contract the transmission rod 18. Pushing the two ends of the blade 7 causes the insert 15 to be pushed back into the corresponding locking hole 12 inside the blade handle 7 as the transmission rod 17 and push frame 16 deflect. This completes the length adjustment of the two blade handles 7 and 8. Then, according to the operator's gripping habits, the two handles 21 and bolts 20 on the outer side of the two connecting plates 6 are turned so that one end of the two bolts 20 is unscrewed from the inner side of the threaded hole 22 in the corresponding connecting plate 4. Then, the fixing angle of the connecting plate 6 and the connecting plate 4 can be adjusted by the positioning shaft 25. Then, the two handles 21 and bolts 20 are screwed back into the two threaded holes 22 inside the connecting plate 4. This completes the positioning angle of the scissor head 1 and blade handle 7. Finally, the operator holds the two handles 10 and pushes them in opposite directions. The positioning shaft 3 causes the two scissor heads 1 to cut in opposite directions, thereby pruning the plant.
