Detailed Implementation

[0017] like Figs. 1 to 3 As shown, a grafting knife includes a first blade body 10 and a second blade body 20. The front of the first blade body 10 is provided with a first cutting head 11, and the front of the second blade body 20 is provided with a second cutting head 21. The first cutting head 11 and the second cutting head 21 are hinged together by fasteners. The rear of the first blade body 10 is provided with a first handle mounting part 12, and a first handle rubber sleeve 13 is installed on the outside of the first handle mounting part 12. The rear of the second blade body 20 is provided with a second handle mounting part 22, and a second handle rubber sleeve 23 is installed on the outside of the second handle mounting part 22. In use, the user holds the first handle rubber sleeve 13 and the second handle rubber sleeve 23 respectively, and closes the first cutting head 11 and the second cutting head 21 by squeezing the handle. The clamping and cutting action between the blades can accurately cut plant branches or scions, thereby providing a flat cutting surface for the grafting process.

[0018] In practical implementation, the first cutting shear head 11 has a cutting blade 111 on its edge away from the second cutting shear head 21, and the second cutting shear head 21 has a cutting blade 211 on its edge facing the first cutting shear head 11. The first cutting shear head 11 has an arc-shaped positioning cutting groove 112 recessed on its edge facing the second cutting shear head 21. The positioning cutting groove 112 corresponds to the cutting blade 211. In use, the branch to be cut is placed between the positioning cutting groove 112 of the first cutting shear head 11 and the cutting blade 211 of the second cutting shear head 21. The arc-shaped design of the positioning cutting groove 112 firmly fixes the branch, preventing it from sliding due to pressure or vibration, thus improving the safety and accuracy of the operation. The user holds the shear head with both hands... By holding the first handle sleeve 13 and the second handle sleeve 23, and squeezing the handles, the first cutting blade 11 and the second cutting blade 21 are closed. The cutting blade 211 interacts with the positioning cutting groove 112 to precisely cut the branch. This process can quickly complete the preliminary cutting work required for grafting. After cutting the branch, the cutting blade 111 of the first cutting blade 11 is used to further refine the cut of the branch. The design of the cutting blade 111 can eliminate unevenness or burrs that may occur during the cutting process, making the cut smooth and flat, and ensuring a perfect fit between the grafted branch and the scion. This design integrates the functions of preliminary cutting and fine trimming in the same tool, reducing the frequency of tool replacement and making the grafting work more continuous, greatly improving work efficiency and convenience.

[0019] In the specific implementation, the surface of the first cutting head 11 is provided with a first hinge hole 113, the surface of the second cutting head 21 is provided with a second hinge hole 212, the first hinge hole 113 corresponds to the second hinge hole 212, and the first hinge hole 113 and the second hinge hole 212 are connected by a fastener, so that the first cutter body 10 and the second cutter body 20 are connected by a hinge, which is simple in structure and convenient to assemble.

[0020] In the specific implementation, the surface of the first handle mounting portion 12 is provided with a plurality of first connecting holes 121, the surface of the first handle rubber sleeve 13 is provided with a plurality of first fixing holes 131, the plurality of first connecting holes 121 correspond to the plurality of first fixing holes 131 one by one, and the first fixing holes 131 and the first connecting holes 121 are connected and fixed by a fastener, so that the first handle rubber sleeve 13 is fixedly sleeved on the outside of the first handle mounting portion 12, which is simple in structure and convenient to install.

[0021] In the specific implementation, the surface of the second handle mounting portion 22 is provided with a plurality of second connecting holes 221, the surface of the second handle rubber sleeve 23 is provided with a plurality of second fixing holes 231, the plurality of second connecting holes 221 correspond to the plurality of second fixing holes 231 one by one, and the second fixing holes 231 and the second connecting holes 221 are connected and fixed by a fastener, so that the second handle rubber sleeve 23 is fixedly sleeved on the outside of the second handle mounting portion 22, which is simple in structure and convenient to install.

[0022] In the specific implementation, the first cutter body 10 and the second cutter body 20 are connected with a reset spring 30, in use, the user squeezes the first handle rubber sleeve 13 and the second handle rubber sleeve 23 to close the first cutter body 10 and the second cutter body 20 to complete the cutting action, in this process, the reset spring 30 is compressed or stretched to store elastic potential energy, when the user releases the handle, the reset spring 30 releases the stored elastic potential energy to push the first cutter body 10 and the second cutter body 20 apart, and the cutter body returns to the initial open state, which is convenient to use.

[0023] In summary, the first cutter body 10 is provided with the first cutting head 11, the second cutter body 20 is provided with the second cutting head 21, the first cutting head 11 and the second cutting head 21 are connected through the fastener hinged connection, the side edge of the first cutting head 11 away from the second cutting head 21 is provided with the cutting blade part 111, the side edge of the second cutting head 21 towards the first cutting head 11 is provided with the cutting blade part 211, and the side edge of the first cutting head 11 towards the second cutting head 21 is concavely provided with the circular-arc-shaped positioning cutting groove 112.
