Description

A tool for cutting propagation Technical Field

[0001] This utility model relates to the field of cutting technology, specifically to a cutting tool. Background Technology

[0002] One type of propagation is bud cutting, which requires using a ring-shaped knife to peel off the appropriate size lateral buds along with the bark from the branch, and then inserting them into another branch.

[0003] Sometimes, the lateral buds collected have already grown into small branches and multiple sets of leaves. At this time, before peeling them off with a ring cutter, it is necessary to first gather the branches and leaves and then insert them into the inner opening of the ring cutter. Because the inner opening of the ring cutter is small, it is not only inconvenient to operate when gathering the branches and leaves and inserting them into the ring cutter, but also easy for the hand to come into contact with the ring cutter, causing injury.

[0004] After a long period of research and development, a deformable environmental cutting tool was designed, which has the function of gathering lateral buds and leaves, thus improving operational safety. Summary of the Invention

[0005] (I) Technical Issues

[0006] The present invention aims to at least solve the problem in the prior art that the fixed structure of the ring blade makes it inconvenient to gather the lateral buds and leaves, which can easily lead to safety hazards.

[0007] (II) Technical Content

[0008] This solution provides a tool for cutting propagation, achieved through the following specific technical means: including...

[0009] Multiple sets of V-shaped cutters are arranged to form a regular polygon;

[0010] The number of vertical bars is the same as the number of V-shaped cutters, and the vertical bars are fixed to the top of the corresponding set of V-shaped cutters;

[0011] The folding rod assembly is connected between two adjacent sets of vertical rods. The distance between the two adjacent sets of vertical rods can be controlled by extending and retracting the folding rod assembly, which in turn controls the change in the distance between adjacent V-shaped cutters. The sides of the adjacent V-shaped cutters make contact to form a ring cutter.

[0012] Preferred technical solution 1: The V-shaped cutter can also replace the layered arc cutter.

[0013] Preferred technical solution 2: The top of the vertical rod away from the annular cutter is also fixed with a grip piece. When multiple sets of arc-shaped cutters or V-shaped cutters come into contact with each other to form an annular cutter, multiple sets of grip pieces form a complete cylindrical shape.

[0014] Preferred technical solution 3: An annular elastic soft stop is fixed inside the space enclosed by multiple sets of vertical rods, and the upper and lower ends of the elastic soft stop are connected to the upper and lower ends of the vertical rods, respectively.

[0015] Preferred technical solution four: A fixing sleeve is fixedly sleeved at the lower part of the vertical rod, and a sliding sleeve is slidably sleeved at the middle part of the vertical rod;

[0016] The folding rod assembly includes rod one and rod two, which cross each other in the middle and are hinged together. The top ends of rod one and rod two are respectively hinged to sliding sleeves on two adjacent sets of vertical rods, while the bottom ends of rod one and rod two are respectively hinged to fixed sleeves on two adjacent sets of vertical rods.

[0017] Preferred technical solution five: A telescopic rod group is also connected between two adjacent groups of vertical rods, and a fixed sleeve two is fixedly sleeved on the upper middle part of the vertical rod. The two ends of the telescopic rod group are respectively hinged to the fixed sleeve two on the two adjacent groups of vertical rods.

[0018] (III) Technical Effects

[0019] The above structure gives this solution the following advantages:

[0020] 1. High efficiency: No manual handling is required for gathering and tidying the lateral buds or for feeding the inner opening of the ring knife;

[0021] 2. High safety: Feeding side shoots and leaves does not require manual operation or getting close to the cutter.

[0022] 3. Minimal damage to branches and leaves: Traditional ring cutters with small diameters may compress and damage branches and leaves during insertion. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Please refer to Figures 1, 2, 3, 4, and 5 for the cutting tool, which includes a V-shaped cutter 11 and a vertical rod 2, wherein:

[0033] There are multiple sets of V-shaped cutters 11, forming a regular polygon structure, and a set of vertical rods 2 are fixed at the outer apex of each set of V-shaped cutters 11.

[0034] Adjacent vertical rods 2 are connected by folding rod groups 6. The spacing between adjacent vertical rods 2 can be controlled by extending and retracting the folding rod groups 6, which in turn controls the spacing between adjacent V-shaped cutters 11. When multiple folding rod groups 6 are extended, the spacing between adjacent vertical rods 2 increases, which in turn increases the spacing between V-shaped cutters 11. At this time, the regular polygonal space enclosed by multiple V-shaped cutters 11 becomes larger, as shown in Figure 4. When the space is stretched to its maximum size, it can be smoothly covered on the lateral bud. Then, the multiple folding rod groups 6 are controlled (while holding multiple vertical rods 2 and applying force) to retract, causing the polygonal space enclosed by multiple V-shaped cutters 11 to shrink until the sides of adjacent V-shaped cutters 11 come into contact to form a complete ring cutter 1 (the size of the ring cutter 1 is consistent with the size of a traditional one-piece ring cutter), as shown in Figure 3. At this time, the lateral bud is completely gathered. Then, the ring cutter 1 is pushed forward to cut into the bark and separate the bark, along with the lateral bud, from the surrounding bark.

[0035] In one embodiment

[0036] The V-shaped cutter 11 can also replace the layered arc-shaped cutter. When the sides of adjacent arc-shaped cutters come into contact with each other, a complete ring-shaped cutter 1 is formed. The arc-shaped cutter can rotate when cutting into the bark, which accelerates the peeling process.

[0037] In one embodiment

[0038] Please refer to Figures 1, 2, and 6. A grip piece 7 is also fixed to the top of the vertical rod 2 away from the ring cutter 1. When multiple sets of arc-shaped cutters or V-shaped cutters 11 contact each other to form the ring cutter 1, the sides of adjacent grip pieces 7 also contact each other to form a complete cylindrical shape for gripping.

[0039] The grip piece 7 can be V-shaped or curved, and it is best to match the shape of the knife.

[0040] In one embodiment

[0041] Please refer to Figure 2. Between two adjacent sets of vertical poles 2, there is an elastic soft barrier 8. That is, the two ends of the elastic soft barrier 8 are fixed to the two sets of vertical poles 2 respectively. Multiple sets of elastic soft barriers 8 form a ring-shaped elastic soft barrier. The elastic soft barrier 8 is located inside the folding pole group 6 to prevent the branches and leaves on the lateral buds from being squeezed when the folding pole group 6 is extended or retracted.

[0042] The flexible soft barrier 8 can be made of transparent or opaque flexible material.

[0043] In one embodiment

[0044] Please refer to Figure 2. In each set of vertical rods 2, a first fixed sleeve 3 is fixedly sleeved at the lower part, a sliding sleeve 4 is provided in the middle of the vertical rod 2, and a second fixed sleeve 5 is fixedly sleeved at the upper middle part of the vertical rod 2.

[0045] The folding rod assembly 6 includes two rods, 61 and 62, which cross each other in the middle and are hinged together. The top ends of rods 61 and 62 are respectively hinged to sliding sleeves 4 on two adjacent sets of vertical rods 2, while the bottom ends of rods 61 and 62 are respectively hinged to fixed sleeves 3 on two adjacent sets of vertical rods 2. When the distance between two adjacent sets of vertical rods 2 is increased, the sliding sleeves 4 move down and closer to the fixed sleeves 3; when the distance between two adjacent sets of vertical rods 2 is decreased, the sliding sleeves 4 move up and away from the fixed sleeves 3.

[0046] To further improve the stability of the connection between two adjacent sets of vertical rods 2, another folding rod group 6 is connected between the two adjacent sets of vertical rods 2. It is also located outside the elastic soft stop 8. To avoid labeling issues, it is referred to as telescopic rod group 9 in the following text. Telescopic rod group 9 includes rod three 91 and rod four 92. The bottom ends of rod three 91 and rod four 92 are hinged together, and the top ends of rod three 91 and rod four 92 are respectively hinged to the fixed sleeve two 5 on the two adjacent sets of vertical rods 2.

[0047] When it needs to be unfolded, pulling the two sets of vertical rods 2 away from each other will trigger the extension and retraction of multiple sets of folding rods 6 and telescopic rods 9.

[0048] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.

[0049] The parts not disclosed in this utility model are all prior art, and their specific structures and working principles will not be described in detail.

[0050] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components.
