[0062] Please refer to the appendix. Figures 2-11 As shown, the grafting device for grafting Chrysanthemum morifolium using Artemisia annua grafting to improve the yield and quality of Chrysanthemum morifolium includes a first handle 10 and a second handle 11 that are hinged to each other.

[0063] The non-handled end of the first handle 10 is provided with a slide 12, on which a blade 13 is connected. The non-handled end of the second handle 11 is provided with a connecting seat 14, which slides relative to the slide 12. (See attached diagram) Figure 2 A sliding groove is provided on the connecting seat 14 to slide with the slide 12. A support seat 15 is provided on the connecting seat 14 and is on the same vertical line as the blade 13. The support seat 15 is mainly to facilitate the placement of the anvil and to provide support during cutting. When the second handle 11 and the first handle 10 are gripped in the middle, the slide 12 and the blade 13 can be driven to move downward along the direction of the connecting seat 14. When the blade 13 moves downward, it cuts the anvil located on the support seat 15.

[0064] The second handle 11 is detachably provided with a storage container 16 for storing plant hormones. In this embodiment, the storage container 16 is a storage bottle and is threadedly connected to the second handle 11. The storage container 16 is connected to a pipe 17. One end of the outlet of the pipe 17 is connected to the blade 13 to apply plant hormones to the surface of the blade 13. The plant hormones delivered from the storage container 16 are transported to the surface of the blade 13 through the pipe 17 to coat the cut surface of the rootstock.

[0065] like Figure 2 , 8 As shown in Figures 9 and 10, in a preferred embodiment, a knife holder 18 is fixedly provided below the slide 12. The knife holder 18 is provided with a receiving cavity 181 that communicates with the pipe 17. Specifically, the receiving cavity 181 is a deep groove with an opening facing downwards on the knife holder 18. The plant hormones drawn from the pipe 17 are sent into the receiving cavity 181.

[0066] A connector 182 is fixedly installed inside the receiving cavity 181. The connector 182 is a fixing block used to be locked inside the receiving cavity 181 and to seal against the side wall of the receiving cavity 181. The gap between the top wall of the receiving cavity 181 and the connector 182 can accommodate the plant hormones led out by the pipe 17. The blade 13 is fixed on the connector 182, and a flow channel 183 is provided inside the connector 182 to connect the receiving cavity 181 and the surface of the blade 13. The flow channel 183 is a through hole provided on the connector 182.

[0067] As a preferred embodiment of the above, the blade 13 has an inclined cutting edge 131. The inclined cutting edge 131 can gradually cut deeper cuts during cutting, avoiding damaging the rootstock in one go.

[0068] The blade 13 has several recessed notches 132 on both sides. The notches 132 are used to draw out the plant hormones in the flow channel 183, so that the plant hormones can stay on both sides of the blade 13 and cover the surface of the blade 13. This allows the plant hormones to come into contact with and be fully coated on the cut of the rootstock or scion. The notches 132 and the flow channel 183 are interconnected. The plant hormones flowing out of the flow channel 183 can flow into the surface of the blade 13 through the notches 132, making it convenient to apply the plant hormones to the cut of the rootstock.

[0069] like Figure 2 As shown, in a preferred embodiment of the above, the second handle 11 is provided with a pumping assembly 19 that connects the storage container 16 and the pipe 17. The pumping assembly 19 faces the first handle 10.

[0070] The first handle 10 is also provided with a squeezing component 20 of the squeezing pump assembly 19. The squeezing component 20 mainly includes a top block that can be pressed against the pump assembly 19. The top block is slidably disposed in the first handle 10, and a return spring is also disposed in the first handle 10. The return spring can push the top block to retract and reset in the first handle 10. A push rod that pushes the top block upward is also rotatably disposed in the first handle 10. By moving the push rod, the top block can be pushed upward to push against the pump assembly 19 and complete the application of plant hormones.

[0071] like Figure 2 , 4As shown, as a preferred mode of the above embodiment, the connecting seat 14 is fixedly provided with a guide 21, which is located at the front side of the supporting seat 15, and the rear side of the supporting seat 15 is provided with a first clamping piece 22. The guide 21 is specifically a semicircular arc guide piece. When the scion is inserted into the stock, the scion can be placed on the guide 21, and then slowly inserted into the stock. The slide seat 12 is further provided with a second clamping piece 23, which can clamp the stock together with the first clamping piece 22. The first clamping piece 22 and the second clamping piece 23 clamp the stock, which can avoid the stock being cut off when cutting.

[0072] The first handle 10 and the second handle 11 are further provided with a locking assembly, which can continuously clamp the stock by the first clamping piece 22 and the second clamping piece 23.

[0073] As shown in Figure 2 , 3 , 5, 6, 7, as a preferred mode of the above embodiment, the locking assembly includes a pushing piece 25 fixed between the first handle 10 and the second handle 11. In this embodiment, the pushing piece 25 is a pushing spring, which is used to push the first handle 10 and the second handle 11 apart.

[0074] The first handle 10 is fixedly connected with a rack 24, and the second handle 11 is rotatably provided with a rotating piece 26. The rotating piece 26 is connected with an incomplete gear ring 27, which is meshed with the rack 24. For details, please refer to the accompanying drawings Figure 3 In this embodiment, only a part of teeth is arranged on the surface of the incomplete gear ring 27. The rotating shaft of the rotating piece 26 is connected with a worm and gear mechanism, and the worm and gear mechanism is connected with a knob 28. For details, please refer to the accompanying drawings Figure 6, by rotating the knob 28, the worm gear can be driven to rotate, thereby driving the rotating part 26 and the incomplete gear ring 27 to rotate, and when the incomplete gear ring 27 rotates, the first handle 10 and the second handle 11 can be controlled to be folded to the middle or expanded outward, so that when the scion is inserted, the position between the first handle 10 and the second handle 11 is fixed by the locking device, and the stock is clamped by the first clamping part 22 and the second clamping part 23, at this time the whole device is clamped on the stock, and then the scion is inserted against the guide part 21, because the first handle 10 and the second handle 11 are not expanded, the blade 13 and the notch on the stock are still in contact, at this time the blade 13 is located between the scion and the stock, so that the plant hormones on the surface of the blade 13 and the scion can be contacted, and then the first handle 10 and the second handle 11 can be slowly expanded by rotating the knob 28, so that the blade 13 can be slowly moved away from the scion and the stock, so as to prevent the scion from being taken out when the scion is inserted, thereby ensuring the stable insertion of the scion and the stock. The blade 13 is not removed from the stock before the scion is inserted, because after the blade 13 is removed from the stock, part of the stock will be tightened to the middle, and the scion cannot be inserted, so that the normal insertion of the scion can be ensured under the blockage of the blade 13, and more plant hormones can be applied to the notch of the scion to improve the healing effect of the notch.

[0075] As shown in Figure 4 、 11 , as a preferred mode of the above embodiment, the connecting seat 14 is fixedly provided with a hollow pipe 33, and the supporting seat 15 is fixedly sleeved on the outside of the hollow pipe 33. Specifically, a fastening bolt is arranged on the outside of the hollow pipe 33, and after the fastening bolt is loosened, the supporting seat 15 can be rotated to replace different supporting surfaces. The hollow pipe 33 is provided with a plurality of spray ports, and the supporting seat 15 is provided with a slot 151 for facilitating the blade 13 to extend into the supporting seat 15;

[0076] A storage container 34 containing disinfectant alcohol is fixedly arranged on the side of the connecting seat 14. The storage container 34 is specifically a storage bottle. The discharge port of the storage container 34 and one end of the hollow pipe 33 are connected by a connecting hose, and a pump head 35 is further arranged on the connecting hose. The pump head 35 and the hollow pipe 33 are fixedly connected with each other. The pump head 35 is also a press pump head. The pump head 35 injects the disinfectant alcohol in the storage container 34 into the hollow pipe 33 by suction, and sprays the disinfectant alcohol onto the blade 13 extending into the supporting seat 15 for disinfection;

[0077] The mounting base of the second clamping piece 23 is further provided with an extrusion protrusion 231, and the second clamping piece 23 can extrude the trigger pump head 35 downward through the through slot on the first clamping piece 22. Specifically, after grafting is completed, the first handle 10 and the second handle 11 are pressed, the slide base 12 drives the blade 13 to extend into the supporting seat 15, and the extrusion protrusion 231 simultaneously extrudes the pump head 35, so that the disinfectant alcohol in the storage tank 34 enters the hollow pipe 33 and is sprayed onto the blade 13 through the spray port to complete disinfection, thereby improving the disinfection efficiency. Due to the blocking effect of the stock during cutting, although part of the blade 13 extends into the supporting seat 15, the extrusion protrusion 231 does not extrude the pump head 35, and the disinfectant alcohol is not extracted, so that the disinfectant alcohol is not sprayed during cutting of the stock. In addition, the hollow pipe 33 is located in the interval between the two blades 13, and when the blade 13 extends into the supporting seat 15, interference between the blade 13 and the hollow pipe 33 can be avoided.

[0078] As shown in Figure 3 , 5 As a preferred mode of the above embodiment, the inner ring of the incomplete gear ring 27 is elastically movably provided with a pawl 271, the pawl 271 is rotatably arranged on the inner ring of the incomplete gear ring 27, and a pressing spring is arranged between the pawl 271 and the incomplete gear ring 27. The outer circumference of the rotating piece 26 is provided with a ratchet 261 that can be clamped with the pawl 271. In this embodiment, the ratchet 261 is only arranged in one part and is symmetrically arranged in two places. When the pawl 271 and the ratchet 261 are clamped with each other, the rotating piece 26 and the incomplete gear ring 27 can be synchronously rotated. Therefore, when the distance between the first handle 10 and the second handle 11 is adjusted by the knob 28, the rotating piece 26 and the incomplete gear ring 27 can be synchronously rotated, and due to the action of the ratchet 261 and the pawl 271, the knob 28 only slowly adjusts the speed of opening of the first handle 10 and the second handle 11.

[0079] The outer circumference of the rotating piece 26 is provided with a deep groove 262 at the same position as the ratchet 261, and a push plate 263 that can contact the pawl 271 is movably arranged in the deep groove 262. The push plate 263 is specifically arranged in an arc shape. When the push plate 263 moves outward, it abuts against the pawl 271, and the pawl 271 and the ratchet 261 lose the mutual pressing action, so that they are separated from each other. Therefore, in this case, the rotating piece 26 and the incomplete gear ring 27 can be rotated relative to each other. When the rotating piece 26 and the incomplete gear ring 27 are rotated relative to each other, the first handle 10 and the second handle 11 can be quickly expanded to both sides under the pushing of the pushing piece 25.

[0080] As shown in Figure 3 , 6As shown in FIG. 7, as a preferred mode of the above embodiment, the center position of the rotating member 26 is further provided with a cavity 264, and a cam 29 is coaxially arranged in the cavity 264, and the rotating shaft of the cam 29 penetrates the rotating shaft of the rotating member 26, and the end of the rotating shaft is fixedly connected with a rotating wheel;

[0081] A slide rod 30 is slidingly arranged between the deep groove 262 and the cavity 264, one end of the slide rod 30 is in contact with the outer edge surface of the cam 29, and the other end is in contact with a push plate 263, and a return spring is arranged between the push plate 263 and the groove bottom of the deep groove 262. When the rotating wheel is rotated, the cam 29 will push the slide rods 30 on both sides, the slide rods 30 will push the push plate 263 outward, the push plate 263 will push the pawl 271, and the pawl 271 and the ratchet teeth 261 will be separated from each other, at this time, the rotating member 26 and the incomplete gear ring 27 can rotate relative to each other, so that the first handle 10 and the second handle 11 can be quickly expanded to both sides. When the rotating wheel is rotated, the cam 29 loses the pushing action on the slide rod 30, and under the pulling action of the return spring, the push plate 263 moves into the deep groove 262 and pushes the slide rod 30 to move to one side of the cam 29. At this time, the pawl 271 and the ratchet teeth 261 can be clamped with each other, so as to limit the rotation of the incomplete gear ring 27, so as to fix the position between the first handle 10 and the second handle 11.

[0082] As shown in FIG. 7, as a preferred mode of the above embodiment, the center position of the rotating member 26 is further provided with a cavity 264, and a cam 29 is coaxially arranged in the cavity 264, and the rotating shaft of the cam 29 penetrates the rotating shaft of the rotating member 26, and the end of the rotating shaft is fixedly connected with a rotating wheel; Figure 2 As shown in FIG. 7, as a preferred mode of the above embodiment, the center position of the rotating member 26 is further provided with a cavity 264, and a cam 29 is coaxially arranged in the cavity 264, and the rotating shaft of the cam 29 penetrates the rotating shaft of the rotating member 26, and the end of the rotating shaft is fixedly connected with a rotating wheel;

[0083] The specific working principle of the device is as follows: first, hold the first handle 10 and the second handle 11, and place the stock between the blade 13 and the supporting seat 15, press the first handle 10 and the second handle 11 to the middle, the blade 13 will cut the stock to the required cut, and through the pressing and extruding assembly 20, the extruding assembly 20 pushes the pumping assembly 19 to send the plant hormone to the surface of the blade 13 and contact with the cut of the stock, and the position of the first handle 10 and the second handle 11 is fixed under the locking of the locking assembly.

[0084] Then the treated scion and the guide 21 are close to and inserted downward to the blade 13, at this time the plant hormones on the blade 13 and the cut of the scion are in contact, then the knob 28 is rotated, the first handle 10 and the second handle 11 are slowly unfolded, at this time the first handle 10 and the second handle 11 need to be held, and in the process of slow unfolding, the blade 13 is slowly removed from the cut between the stock and the scion, so as to avoid taking out the scion together when the blade 13 is taken out, then the scion is adjusted to ensure that the formation layer is aligned.
