[0002] Fruit tree pruning is an agricultural technique that involves removing some of the tree's vegetative organs to adjust the canopy structure and renew the composition of branches and leaves. The purpose of fruit tree pruning is to regulate the distribution of branches and leaves to balance the growth and fruiting of the fruit tree. Regular pruning can rejuvenate the fruit tree.

[0003] Most existing fruit tree pruning methods involve manually pruning redundant branches with specialized shears. While specialized shears are convenient to use, and with the help of the staff's analysis and judgment, the blades can be quickly and accurately aligned with the branches to complete the pruning. After pruning, a healing agent is usually applied to the pruning site to prevent the wound from rotting. However, existing pruning tools lack a structure that allows for timely pruning after pruning, making it difficult for staff to carry out branch pruning and wound treatment simultaneously.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model provides, for example Figure 1 - Figure 5 The illustrated convenient pruning device for fruit tree planting includes a first blade 1, a second blade 2 on one side of the first blade 1, and an extension handle 3 fixedly connected to the ends of both the first blade 1 and the second blade 2. A handle 6 is connected to the ends of both extension handles 3. A connecting rod 10 is provided on the outer wall of one of the handles 6, and a medicine-holding device is connected to the end of the connecting rod 10. The medicine-holding device includes a medicine-filling tube 7 located at the end of the connecting rod 10. A first sliding piston 13 is provided at one end of the medicine-filling tube 7, and a medicine brush is provided at the other end. A piston rod 8 is fixed to one end of the first sliding piston 13. The medicine brush includes a second sliding piston 15, a brush handle 9 is fixed to one end of the second sliding piston 15, and a bristle part 16 is fixed to the other end. The bristle part 16 and the second sliding piston 15 can move inside the medicine-filling tube 7.

[0024] In this embodiment, during the pruning of fruit trees, the user holds two handles 6 with his left and right hands respectively, and then pulls the handles 6 in opposite directions. The handles 6 drive two extension handles 3, and the two extension handles 3 drive the first blade 1 and the second blade 2 respectively. After the first blade 1 and the second blade 2 are in the open state, the branches of the fruit tree are cut off. After the branches are cut off, the user pulls out the brush handle 9 with his hand. The brush handle 9 drives the second sliding piston 15 and the bristle part 16. At this time, the bristle part 16 is coated with medicine. The medicine is applied to the pruning wound of the fruit tree. After applying the medicine, the bristle part 16 and the second sliding piston 15 are inserted into the medicine loading tube 7.

[0025] It should be noted that the drug mentioned in this application is a healing agent. The healing agent is usually in a gel state. After the brush part 16 and the second sliding piston 15 are pulled out, the healing agent will not flow inside the drug delivery tube 7 and will not automatically detach from the drug delivery tube 7.

[0026] The first sliding piston 13 and the second sliding piston 15 are both made of rubber. The outer walls of the first sliding piston 13 and the second sliding piston 15 rub against the inner wall of the drug loading tube 7. The first sliding piston 13 and the second sliding piston 15 will only move when pulled by the staff. Under normal conditions, the first sliding piston 13 and the second sliding piston 15 cannot move automatically inside the drug loading tube 7.

[0027] like Figure 1 - Figure 5 As shown, a connecting rod 12 is fixed to the end of the traction handle 11. The outer wall of the end of the connecting rod 12 is provided with an external thread. The end of the piston rod 8 is provided with a threaded groove that matches the connecting rod 12. The end of the handle 6 is provided with a slot. The traction handle 11 and the connecting rod 12 can be inserted into the slot. The first sliding piston 13 is fixed with a rod 14 at one end relative to the piston rod 8.

[0028] During the loading process, the piston rod 8 is manually pulled, which drives the first sliding piston 13. The first sliding piston 13 disengages from the loading tube 7, and the drug is injected from this end. Then, the first sliding piston 13 is pushed into the loading tube 7. Pushing the piston rod 8 will push the first sliding piston 13, thereby using the first sliding piston 13 to push the drug. If there is not much drug inside the loading tube 7, the user can pull the traction handle 11. The traction handle 11 drives the connecting rod 12 to disengage from the handle 6. Then, the end of the connecting rod 12 is connected to the end of the piston rod 8 by threading. By pushing the traction handle 11, the first sliding piston 13 is pushed, thereby using the first sliding piston 13 to push the remaining drug inside the loading tube 7. The drug moves towards the bristle part 16, making it easier for the bristle part 16 to pick up the drug.

[0029] like Figure 1 As shown, a fixing seat 4 is fixed to the inner wall of the extension handle 3, and an elastic element 5 is fixed to the end of the fixing seat 4. During the branch cutting process, after the branch is cut, the two handles 6 are in a process of moving closer to each other. During this process, the handle 6 drives the extension handle 3, the extension handle 3 drives the fixing seat 4, the fixing seat 4 drives the elastic element 5, the two elastic elements 5 move closer to each other and are squeezed, and deform at the same time. After releasing, the two elastic elements 5 can automatically spring open, so that the two handles 6 separate.

[0030] like Figure 1 , Figure 4 and Figure 5As shown, the sidewalls of the first cutting edge 1 and the second cutting edge 2 are provided with a through hole, and a threaded tube 19 is provided in the through hole. One end of the threaded tube 19 is threadedly connected to the main connector 18, and the other end is threadedly connected to the auxiliary connector 21.

[0031] The main connector 18 includes a main nut portion 181, one end of which is fixed with a first screw portion 182, and one end of which is fixed with a secondary connecting screw 183. The auxiliary connector 21 includes an auxiliary nut portion 213, one end of which is fixed with a second screw portion 212, and one end of which is provided with a secondary connecting thread groove 211.

[0032] Both the main nut part 181 and the auxiliary nut part 213 are internal hexagonal nuts, and six threaded holes 184 are provided at the ends of both the main nut part 181 and the auxiliary nut part 213. The side walls of the first cutting edge 1 and the second cutting edge 2 are provided with threaded seats 20. The surface of the threaded seat 20 is provided with six threaded holes that match the threaded holes 184. Locking bolts 17 are threadedly connected in the threaded holes 184.

[0033] In this embodiment, during the installation process, the threaded tube 19 is passed through the through holes of the first blade 1 and the second blade 2. Then, the main connector 18 is threaded and fastened from one end of the threaded tube 19, and the auxiliary connector 21 is threaded and fastened from the other end of the threaded tube 19. During the connection process between the auxiliary connector 21 and the threaded tube 19, the secondary connecting screw 183 of the main connector 18 and the secondary connecting thread groove 211 of the auxiliary connector 21 are also threadedly engaged. During this process, the main connector 18 and the auxiliary connector 21 are also connected together.

[0034] After the first cutting edge 1 and the second cutting edge 2 are connected by the main connecting member 18, the threaded tube 19 and the auxiliary connecting member 21, and the main connecting member 18 and the auxiliary connecting member 21, the first cutting edge 1 and the second cutting edge 2 are close to each other, but not completely fastened, and the first cutting edge 1 and the second cutting edge 2 can rotate around the threaded tube 19.

[0035] Locking bolts 17 are connected to the ends of the main connector 18 and the secondary connector 21 by threaded engagement in the screw holes 184 of the main nut part 181 and the secondary nut part 213. Finally, the end of the locking bolt 17 is connected to the threaded seat 20 on the outer wall of the first blade 1 and the second blade 2 by threaded engagement. The first blade 1 and the second blade 2 are further connected by the locking bolt 17. At this time, the main connector 18 is fixed on the first blade 1 and the secondary connector 21 is locked on the second blade 2.

[0036] It should be noted that the first blade 1 and the second blade 2 rotate around the threaded tube 19 as the main axis. By pulling the two handles 6, the first blade 1 and the second blade 2 can be opened. When the two handles 6 are brought close together, the first blade 1 and the second blade 2 can cut the branches and sever them. It should be noted that during the rotation of the first blade 1 and the second blade 2, the first blade 1 drives the main connecting member 18 to rotate as a whole, and the second blade 2 drives the secondary connecting member 21 to rotate as a whole. The first screw part 182 of the main connecting member 18 rotates in the threaded groove inside the threaded tube 19, and the second screw part 212 of the secondary connecting member 21 also rotates in the threaded groove inside the threaded tube 19. The rotation of the main connecting member 18 and the secondary connecting member 21 is unrestricted.

[0037] The main connector 18 and the secondary connector 21 form a fastening assembly. The first blade 1, the second blade 2, and the fastening assembly form a shearing assembly. The shearing assembly mainly has the function of shearing the branches of the fruit tree.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
