[0022] A pine grafting knife, comprising: a knife handle 1, a cutting knife groove 2 is provided at the bottom of the knife handle 1, a telescopic shell 3 is movably installed inside the cutting knife groove 2, a rotating hole 4 is provided on the upper side of the knife handle 1, a telescopic slot 5 is provided on the right side of the telescopic shell 3, a cutting knife body 6 is detachably and concealedly arranged inside the telescopic slot 5, through holes 7 are evenly provided on the upper side of the cutting knife body 6, a shearing knife groove 13 is provided at the bottom of the knife handle 1, a first shearing knife edge 14 is fixedly provided on the upper side of the shearing knife groove 13, the first shearing knife edge 14 is provided with the bottom of the knife handle 1, a rotating block 15 is fixedly installed on the left side of the knife handle 1, a shearing knife body 16 is movably installed inside the rotating block 15, and a second shearing knife edge 17 is provided on the upper side of the shearing knife body 16;

[0023] Among them, the cutting knife groove 2 can facilitate the placement of the telescopic shell 3 and the cutting knife body 6, and the setting of the rotating hole 4 can facilitate the positioning of the knife handle 1 and the telescopic shell 3. By using the cutting knife body 6, the first shearing edge 14, the shearing knife body 16 and the second shearing edge 17, an effective combination of branch pruning and grafting can be achieved, overcoming the single function of ordinary pruning shears, eliminating the need to purchase a grafting knife separately, saving costs, and realizing the versatility of pruning shears.

[0024] A positioning hole 8 is provided on the upper side of the telescopic shell 3, and a positioning pin 9 is detachably installed inside the positioning hole 8. The positioning pin 9 is made of cast iron. The telescopic shell 3 and the cutting knife body 6 are positioned by the positioning pin 9.

[0025] Among them, the setting of the positioning hole 8 and the positioning pin 9 realizes the adjustment of the position of the cutting knife body 6, which is convenient for using the tool in different situations. The cutting knife body 6 can be replaced by taking out the positioning pin 9. The positioning pin 9 is set to cast iron material, which is more firm when positioning the telescopic shell 3 and the cutting knife body 6, and can enhance the stability of the cutting knife body 6 during installation.

[0026] The top of the cutting blade body 6 is evenly provided with a serrated blade edge 10;

[0027] Among them, the serrated blade 10 can be used to prune trees and branches. Using pruning shears with a serrated blade 10 can complete the task more conveniently and efficiently. The sharp tooth-like edge of the serrated blade 10 can easily penetrate the bark and wood parts of the tree, making the pruning work easier.

[0028] A knife groove 11 is provided at the bottom of the knife handle 1, and a knife body 12 is movably installed inside the knife groove 11;

[0029] Among them, when the small knife groove 11 is working, the small knife groove 11 is restricted by the small knife groove 11 inside the knife handle 1, thereby ensuring the stability of the small knife groove 11 when working, and ensuring the structural strength and structural toughness of the knife.

[0030] A lamp placement slot 18 is provided at the bottom of the knife handle 1, a battery 19 is detachably installed inside the lamp placement slot 18, a wire 20 is connected to the left side of the battery 19, and a control switch 21 is detachably installed on the upper side of the wire 20;

[0031] Among them, the internal components of the lamp placement groove 18 can be disassembled and installed. The battery 19 can be used to convert external electrical energy into internal electrical energy and release it as electrical energy to provide electrical energy to the lighting lamp panel 22, thereby enhancing the flexibility of engineering equipment installation.

[0032] A lighting board 22 is fixedly mounted on one end of the wire 20 away from the battery 19, a positioning board 23 is evenly mounted on the upper side of the lighting board 22, and a fastening screw 24 is threadedly mounted on the upper side of the positioning board 23;

[0033] Among them, multiple light tubes are arranged above the lighting board 22, which increases the range of lighting and further ensures the stability of the grafting tool during operation. The positioning plate 23 and the lighting board 22 are fixedly installed. By setting the fastening screw 24, the lighting board 22 can be positioned more stably and firmly. At the same time, it is also more convenient to disassemble the lighting board 22, making it more labor-saving for workers to use.

[0034] The outer side of the knife handle 1 is detachably covered with an anti-slip cover 25, and the material of the anti-slip cover 25 is rubber material, and the anti-slip cover 25 can be reused;

[0035] Among them, the anti-slip cover 25 is put on the outer surface of the knife handle 1 to protect the knife handle 1, which can increase the friction between the palm and the surface of the knife handle 1, and can effectively avoid the sliding phenomenon between the user's palm and the knife handle 1, which is convenient for the user to use, reduces the probability of damage to the grafting knife, improves the protection performance, and further ensures the stability of the knife handle 1 when working.

[0036] In summary, the utility model provides a pine grafting knife. When working, the cutting knife body 6 is first taken out from the cutting knife groove 2, and then the positioning pin 9 is taken out from the positioning hole 8 according to the use requirements, and the cutting knife body 6 is pulled out from the telescopic groove 5 until the cutting knife body 6 is pulled to a suitable position. The cutting knife body 6 is aligned with the position to be cut and cut. When the cutting knife body 6 is not in use, the cutting knife body 6 is stored in the cutting knife groove 2 to avoid accidental injury when not in use. The shearing knife body 16 at the bottom and the auxiliary first shearing blade 14 and the second shearing blade 17 cooperate with each other to cut off the branches. At the same time, the serrated blade 10 on the top of the cutting knife body 6 can saw off the branches with thicker diameters. When used for fruit tree grafting, the knife body is provided with four blades, namely the cutting knife body 6, the serrated blade 10, the small knife body 12 and the shearing knife body 16, which is conducive to application on different types of trees, can effectively reduce the probability of damaging the wood while peeling the bark, and avoid carrying a large number of single-blade and single-function knife bodies to ensure the quality of grafting.
