Description

Technical Field

[0001] This utility model relates to the field of horticultural operation technology, specifically an adjustable-angle ring-cutting knife for horticultural operations. Background Technology

[0002] In horticulture, a girdling knife (also known as a ring bark or ring cutter) is a tool specifically used for girdling plant stems. This helps control the vigor of fruit trees, preserves flowers and fruit, significantly increases flowering and fruit yield, reduces fruit cracking, and improves the yield and quality of fruit in the following year.

[0003] However, existing circumcision cutters still have certain defects. During use, existing circumcision cutters are not convenient for fixing the opening angle, which can easily lead to the opening becoming larger during the circumcision process, thus affecting the circumcision effect. In addition, existing circumcision cutters use bolts to tighten and adjust the angle of the blade. When the force is too great, the clamping effect of the bolts is insufficient, which can cause the blade to slip and cause the angle to deviate.

[0004] Based on this, an adjustable-angle girdling knife for gardening operations is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-4 As shown, an adjustable angle ring cutter for gardening includes a first handle 1, a support ring 11 is installed on one side of the top of the first handle 1, a damping shaft 13 is installed in the middle of the inside of the first handle 1, and an adjusting bolt 14 is provided inside the damping shaft 13.

[0029] The adjusting bolt 14 is covered with an adjusting component;

[0030] A limit component is installed on one side of the top of the first handle 1;

[0031] The outer layer of the support ring 11 is rotatably connected to a rotating assembly, which includes a rotating ring 3. The inner side of the rotating ring 3 is equipped with meshing teeth 31, and a connecting bolt 32 is connected through one side of the rotating ring 3.

[0032] The connecting bolt 32 has a circumferential cutting assembly in the middle.

[0033] In this embodiment, the first handle 1 and the second handle 19 are connected by the damping shaft 13. The damping force of the damping shaft 13 can be adjusted by the adjusting bolt 14. The rotating component is supported by the support ring 11. The adjusting component can be used to adjust the adjusting bolt 14. The meshing teeth 31 inside the rotating ring 3 mesh with the gear 22 in the lifting component, thereby facilitating the positioning of the angle of the blade 34.

[0034] In one embodiment, such as Figure 1 and Figure 2As shown, the adjusting assembly includes a sleeve 15, which wraps around the outside of the adjusting bolt 14. A strong magnetic plate 16 is installed inside the sleeve 15. A rotating handle 17 is installed on the top of the sleeve 15, and a pull ring 18 is installed on the top of the rotating handle 17. By pulling the pull ring 18, the magnetic attraction between the strong magnetic plate 16 and the adjusting bolt 14 is separated, thereby removing the sleeve 15.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the first handle 1 is rotatably connected to the first guide wheel 12, and the bottom of the damping shaft 13 is equipped with a second handle 19. The second handle 19 is rotatably connected to the second guide wheel 110. The second guide wheel 110 and the first guide wheel 12 fit together with the tree trunk that needs to be girdled, thereby playing a supporting role.

[0036] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the limiting component includes a limiting rod 2, which is installed on the top side of the first handle 1. A limiting plate 21 is installed on the top of the limiting rod 2. The limiting plate 21 limits the gear 22, thus preventing the gear 22 from rotating. The limiting plate 21 also limits the sliding of the gear 22.

[0037] In one embodiment, such as Figure 1 and Figure 3 As shown, a lifting assembly is slidably connected to the outer side of the limiting rod 2, and the gear 22 is driven to move up and down through the lifting assembly.

[0038] In one embodiment, such as Figure 1 and Figure 3 As shown, the lifting assembly includes a gear 22, which is slidably connected to the outside of the limiting rod 2. A support frame 23 is installed on the top of the gear 22, and a buckle 24 is installed in the middle of the top of the support frame 23. By pulling the buckle 24, the gear 22 is moved upward through the support frame 23.

[0039] In one embodiment, such as Figure 1 and Figure 4 As shown, the circumferential cutting assembly includes a connecting plate 33, which is connected to the rotating ring 3 by a connecting bolt 32. A blade 34 is installed on one side of the connecting plate 33. The connecting plate 33 is connected to the rotating ring 3 by the connecting bolt 32 so as to facilitate the disassembly and replacement of the blade 34.

[0040] The above embodiment discloses an adjustable-angle ring-cutting knife for gardening operations. The rotation of the damping shaft 13 adjusts the first handle 1 and the second handle 19 to a suitable angle. Rotating the handle 17 causes the sleeve 15 to rotate, thereby adjusting the internal adjusting bolt 14 of the damping shaft 13 and adjusting the rotational force of the damping shaft 13. Increasing the rotational force of the damping shaft 13 facilitates the positioning of the angles of the first handle 1 and the second handle 19. Pulling the pull ring 18 upwards disengages the strong magnetic plate 16 inside the sleeve 15 from the adjusting bolt 14, allowing the sleeve 15 to be removed. This improves the convenience and practicality of the ring-cutting knife. Pulling the latch 24 upwards, via the support frame 23 and the gear 22 outside the limiting rod 2, moves the knife upwards. The gear 22 slides, disengaging from the rotating ring 3. The gear 22 is limited by the limiting plate 21, preventing it from disengaging from the limiting rod 2. The rotating ring 3 rotates outside the support ring 11, adjusting the angle of the blade 34. Once the blade 34 is adjusted to the appropriate angle, the pull buckle 24 is pushed, causing the gear 22 to slide downwards outside the limiting rod 2. The engagement between the gear 22 and the meshing teeth 31 positions the rotating ring 3, preventing the blade 34 from shifting due to excessive force during ring cutting. This improves the stability of the ring cutting blade's angle adjustment. The connecting plate 33 is connected to the rotating ring 3 by the connecting bolt 32, facilitating the removal and replacement of the blade 34 and improving the convenience of the ring cutting blade.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
