Description

Technical Field

[0001] This utility model relates to the field of garden tool technology, specifically to a pruning device for landscaping. Background Technology

[0002] Pruning is a crucial management practice in landscaping and plant cultivation. Pruning removes messy, crossing, overlapping, and overgrown branches, shaping trees into neat, aesthetically pleasing forms that meet aesthetic requirements. Traditional landscaping pruning often uses handheld pruning tools, such as garden shears and high-branch shears, for small areas and low-lying branches.

[0003] Traditional garden shears have a fixed handle length. For pruning branches at certain heights, workers need to switch to shears with longer handles. Therefore, they need to carry more tools during pruning, which increases their burden. In addition, the blades of traditional garden shears are fixed to the frame, and the blades will become dull after long-term use, causing workers to expend more physical strength and reducing pruning efficiency. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1

[0030] Combined with appendix Figures 1 to 3 As shown, a pruning device for landscaping includes two shear frames 1 connected by a pin hinge. One end of each shear frame 1 has a mounting groove 2, into which a detachable shear blade 3 is engaged. The other end of each shear frame 1 is connected to an adjustable handle 4 via an adjusting assembly. The adjusting assembly includes an extension rod 6 fixed to one end of the handle 4. A through groove is formed inside each shear frame 1, into which the extension rod 6 is inserted. Each shear frame 1 has a slot 7 communicating with the through groove. A screw 8 is connected to the extension rod 6, slidingly positioned within the slot 7. One end of the screw 8 extends to the outside of the slot 7 and is threadedly connected to a fastening nut 9. A rubber gasket 13 is fitted over the outside of the screw 8, located between the fastening nut 9 and the shear frame 1.

[0031] The user adjusts the length of the handle 4 according to the height of the sapling to be pruned, loosens the fastening nut 9 on the screw 8, and at this time the screw 8 can slide freely in the slot 7 of the scissor holder 1. After adjusting the handle 4 to a comfortable and easy-to-operate length, turn and tighten the fastening nut 9 to make it fit tightly against the surface of the scissor holder 1 until it cannot be turned, thereby firmly fixing the extension rod 6 in the through slot, ensuring the stability of the handle 4 length, and preventing the handle 4 from accidentally extending or loosening during the pruning operation. At the same time, the design of the rubber pad 13 increases the friction between the two and improves the stability of the fixation.

[0032] To prevent accidental opening of the device when not in use and potential injury to the user, in conjunction with the attached... Figure 1 , Figure 4 , Figure 6 and Figure 7 As shown, it also includes a safety locking assembly, which includes a pin 14. One of the handles 4 has a groove 15, and the pin 14 is connected to the groove 15 by a spring 16. The other handle 4 has a through hole 17 that matches the pin 14. A pressing rod 18 is inserted into the through hole 17. One end of the pressing rod 18 extends to the outside of the handle 4. A sliding groove 19 is provided in the through hole 17. A sliding plate 20 is provided on the pressing rod 18. The sliding plate 20 slides in the sliding groove 19. A spring 21 is sleeved on the pressing rod 18, with both ends abutting against the inner walls of the sliding plate 20 and the sliding groove 19, respectively.

[0033] When not in use, the two scissor holders 1 overlap and close, with the pin 14 inserted into the through hole 17 to securely lock the handle 4, preventing the scissor blades 3 from suddenly opening due to accidental collision, falling, or accidental contact, effectively preventing the blades from cutting the user or people around them. When needed, press the pressing rod 18 inward to push the pin 14 out of the through hole 17 and retract it into the groove 15. At this time, the locking of the two handles 4 can be released. After releasing the pressing rod 18, the pin 14 and the pressing rod 18 will spring back to their original positions under the action of spring 16 and spring 21.

[0034] Among them, the combination of appendix Figure 1 As shown, a limiting plate 22 is connected to the side of the scissor holder 1 near the handle 5. The thickness of the limiting plate 22 is greater than the thickness of the scissor holder 1. The limiting plate 22 restricts the rotation range of the scissor holder 1, preventing excessive rotation.

[0035] Example 2

[0036] Garden shears dull their blades over time. To maintain pruning efficiency, based on Example 1, and in conjunction with the attached... Figure 4 and Figure 5As shown, a T-shaped groove 10 is provided on one side of the mounting groove 2, and a magnet 11 is embedded in the inner wall of the T-shaped groove 10. One end of the scissor blade 3 is connected to an iron connecting block 12 that is adapted to the T-shaped groove 10.

[0037] The scissor blade 3 is magnetically fixed in the T-slot 10, which not only ensures the stability of the scissor blade 3 during use, but also facilitates the disassembly and assembly of the scissor blade 3. Depending on different pruning needs, such as pruning thin branches, thick branches, or different plant types, the appropriate scissor blade 3 can be flexibly replaced, or a sharper scissor blade 3 can be replaced, improving the versatility of the device and the efficiency of pruning.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
