Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of agricultural tools, in particular to a pair of cutting and cutting shears. Background Art
[0002] Cutting is a method of asexual plant propagation, which means cutting a part of the vegetative organs such as stems, roots, leaves, etc. containing buds from the mother plant, inserting it into a substrate (such as soil, perlite, vermiculite, etc.), and promoting the rooting and germination of these vegetative organs under suitable environmental conditions, thus forming an independent new plant. This method does not require seeds and can maintain the genetic characteristics of the mother plant. It is often used in horticultural propagation, fruit tree cultivation, flower cultivation and other fields.
[0003] In modern agricultural production, cutting propagation is widely used as an important asexual propagation method. When existing cutting shears are used to cut branches, due to the round surface of the branches, the contact area between the blade of the cutting shears and the branches is small, which is prone to slippage, affecting the efficiency of cutting the branches, and causing uneven cutting of the branches, damaging plant tissues, and in severe cases causing harm to the operator. In addition, different plant species and branch thicknesses require different cutting forces and angles, making it difficult for single-function cutting shears to meet diverse needs. Therefore, the development of a new type of cutting cutting shears to improve operating efficiency and cutting accuracy has become a problem that needs to be solved urgently in current agricultural production.

[0030] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Example:
[0032] like Figures 1 to 6 As shown, a cutting cutting shear includes an X-shaped hinged connecting rod 3, and a shearing head 1 is provided at both ends of the left side of the X-shaped hinged connecting rod 3. The shearing head 1 is movably connected to the X-shaped hinged connecting rod 3 by adjusting the connecting assembly 2. Both ends of the right side of the X-shaped hinged connecting rod 3 are fixedly connected with handles 4. The front end of the shearing head 1 is a pointed structure, and its inner side is a shearing blade 11. The inside of the shearing blade 11 is provided with a limiting groove 12 of an arc structure. This design solves the problem that when the existing cutting shears are cutting branches, the contact area between the blade of the cutting shears and the branches is small due to the circular surface of the branches, which is easy to slip, affecting the cutting efficiency of the branches, and causing uneven cutting of the branches, damaging plant tissues, and causing harm to the operator in severe cases. In addition, different plant species and branch thicknesses require different cutting forces and angles, making it difficult for single-function cutting shears to meet diverse needs.
[0033] A plurality of sets of saw teeth 13 are evenly arranged inside the limiting groove 12. When the shearing blade 1 is closed, the saw teeth 13 can be deeply embedded in the surface of the branch, increasing the friction during shearing, effectively preventing the branch from slipping during shearing, and ensuring the stability of cutting. At the same time, the saw teeth 13 can increase the shearing force on the branch, promote the shearing of the branch, and make the entire shearing process more efficient.
[0034] The outer side of the shearing blade 1 is fixedly provided with an arc-shaped positioning plate 14, and the edge of the positioning plate 14 is aligned with the edge of the limiting groove 12. The positioning plate 14 is provided to limit and fix the branches, and can be close to the outer side of the branches during shearing, forming a clamping effect with the inner shearing blade 11, effectively fixing the branches, especially for thinner or softer branches, to prevent them from being offset or twisted during the shearing process, ensuring the accuracy of the cutting position. At the same time, the positioning plate 14 can increase the contact area with the branches, increase the friction, and then effectively prevent the branches from sliding, ensuring the shearing effect on the branches.
[0035] The adjustment connection assembly 2 includes an adjustment bolt 21, an articulated seat 22 and an articulated head 23. The articulated head 23 is fixedly arranged at the inner end of the shearing head 1. The articulated seat 22 is fixedly arranged at the left end of the X-shaped articulated connecting rod 3. The articulated head 23 and the articulated seat 22 are connected by the adjustment bolt 21. The adjustment bolt 21 is screwed with the articulated head 23 and the articulated seat 22. Through the setting of the adjustment connection assembly 2, the user can rotate and adjust the angle of the shearing head 1 to adjust the angle between the shearing head 1 and the branches, so as to achieve shearing of branches at different angles.
[0036] The relative contact surfaces of the articulated seat 22 and the articulated head 23 are both provided with dense micro-grips 24. The micro-grips 24 will bite each other when the articulated head 23 and the articulated seat 22 are docked, ensuring the stable connection between the articulated head 23 and the articulated seat 22, and can fix the shearing head 1 at the current position after adjusting the angle, which is not easy to loosen, thereby improving the stability and accuracy of the shearing process.
[0037] An elastic steel sheet 7 with an arc structure is arranged on the right side inside the X-shaped hinged connecting rod 3, the lower end of the elastic steel sheet 7 is fixedly connected to the inner side of the X-shaped hinged connecting rod 3, and the upper end thereof is in contact connection with the X-shaped hinged connecting rod 3. The elastic steel sheet 7 can generate a directional elastic force inside the X-shaped hinged connecting rod 3, so that the shearing blade 1 can automatically return to its original position after the shearing action is completed, thereby improving the convenience of use. In addition, the elastic steel sheet 7 can also disperse the impact force generated during shearing, reduce the direct stress on the structure of the X-shaped hinged connecting rod 3, and thus extend the service life of the entire tool.
[0038] A rubber grip 5 is provided on the outside of the handle 4. The rubber material has good softness and elasticity and can fit the shape of the hand. Even after long-term use, it can reduce hand fatigue and improve the comfort of operation. At the same time, the rubber grip 5 can increase the friction with the hand, ensure good grip stability, avoid accidental slipping during use, and ensure safe operation.
[0039] The lower handle 4 is rotatably connected to a connecting rod 6 near the right end, and a positioning hole 8 is opened inside the upper handle 4, and the upper end of the connecting rod 6 can be inserted into the positioning hole 8. By inserting the upper end of the connecting rod 6 into the positioning hole 8, a closed connection between the handles 4 can be achieved, and the shear head 1 can be closed when not in use to prevent accidental touch and cause injury.
[0040] The connecting rod 6 is made of elastic steel wire. The use of elastic steel wire ensures that the connecting rod 6 has sufficient flexibility and elasticity, so that the connecting rod 6 can be slightly deformed and inserted into the positioning hole 8 during use. The middle part of the connecting rod 6 is set as an arc structure, which provides a hanging force point for the scissors, making it convenient to hang, store or carry the scissors.
[0041] The right end of the lower handle 4 is fixedly connected with a punching head 9, the outer end of the punching head 9 is a cone-shaped structure, and a protective cap 10 is sleeved on the outer side of the punching head 9. The punching head 9 is convenient for punching holes on the cultivation substrate after shearing is completed, and cutting operations are performed without switching to another tool, which greatly improves work efficiency. At the same time, the protective cap 10 can not only protect the punching head 9 from external damage when not in use and keep it sharp, but also ensure the safety of the user and prevent accidental punctures when carrying or storing.
[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
