[0017] A working method of a handheld plant grafting device, firstly, the diameter-changing handle is rotated to push the striker to clamp the branch as a grafting carrier, after pressing the switch, the motor drives the groove cam and the scissor cam to rotate through the main shaft, and the cross-cutting mechanism moves forward, and during the forward movement, the scissor cam is in idle rotation; then, when it reaches the specified position, although the groove cam is still rotating, the cross-cutting mechanism no longer moves, and the scissor cam contacts the sharp end of the blade and pushes it to complete the cross-cutting process; then, the groove cam continues to rotate to drive the cross-cutting mechanism back to the initial position, and at the same time, the rotation of the main shaft drives the crank to rotate, and the crank slides The block principle pushes the motor rack forward, which in turn drives the motor pinion and the motor gear to rotate. The power will be transmitted to the knife gear through the transition gear, so that the knife rack moves toward the branch direction, allowing the blade below to cut the branch; the side of the floating head is a designed curved surface.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] like Figure 1-4 As shown, a handheld plant grafting device is divided into three parts as a whole: a cross-cutting mechanism, a longitudinal cutting mechanism, and a seedling placing mechanism.
[0033] The cross-cutting mechanism is composed of a reducing handle 1, a handle fixing part 2, a reducing handle 3, a sharp end of a knife edge 6, a scissor cam 7, a groove cam 8, a linkage key 25, a cross-cutting base plate 27, a frame fixing part 30, a main shaft 31, a striker 32, and a motor 34.
[0034] The handle fixing part 2 is fixed to the cross-cutting base plate 27 by bolts. The reducing handle part 3 is connected to the reducing handle head 1 by welding. The striker 32 is covered with a spring on the outside, and the frame fixing part 30 is connected to the cross-cutting base plate 27 by bolts. The scissor cam 7 and the groove cam 8 are fitted on the main shaft 31 through keys and keyways. The bottom of the main shaft is a special-shaped hole, which passes through the cross-cutting base plate 27 and fits with the rotating shaft of the motor 34. There is a cylindrical boss below the linkage key 25, which is embedded in the groove of the groove cam 8, and the tail is connected to the longitudinal cutting base plate 31 through a slide rail slider. The front half of the sharp end 6 of the blade is connected to the linkage key 25 through bearings and rivets, and the rear half is in contact with the scissor cam 7 through bearings. At the same time, a compression spring is sleeved between the cylinder above the sharp end 6 of the blade and the cylinder above the linkage key 25 to ensure the opening of the scissor mouth.
[0035] The longitudinal cutting mechanism is composed of a bearing support seat 4, a bearing support plate 5, a crank 9, a connecting rod 10, a motor rack 28, a motor rack fixing plate 11, a motor gear 12, a bottom plate 13, a motor pinion 14, a transition gear 15, a transition gear shaft 16, a knife gear 17, a knife rack 18, a knife gear shaft 19, a floating head 23, a side bending seat 24, a blade 26, a slide rail clip 29, and a side bending bearing 33.
[0036] The bearing support sheet 5 is connected to the bearing support seat 4 by bolts. The crank 9 is embedded in the main shaft 31 by a standard key. The front end of the connecting rod 10 is connected to the crank 9 by bolts, and the rear end is opened to fit with the boss above the motor rack 28. The motor rack fixing sheet 11 is connected to the bottom plate 13 by bolts, and the other side presses the motor rack 28 to prevent it from tipping over. The motor rack 28 and the motor pinion 14 are gear racks, and the motor gear 12 is bonded to the motor pinion 14 as a whole, and is connected to the shaft on the bottom plate 13 through a bearing. The transition gear 15 and the transition gear shaft 16 are fitted with a bearing and matched with the motor gear 12. The transition gear shaft 16 is bonded to the bottom plate 13. At the same time, the transition gear 15 rotates in coordination with the cutter gear 17, and the cutter gear 17 is fitted on the cutter gear shaft 19 through a bearing, and is matched with the cutter rack 18 as a gear rack. There is a slider inside the cutter rack 18, which matches the slide rail on the bottom plate 13. The cutter gear shaft 19 is bonded to the bottom plate 13. The slide rail clip 29 is connected to the bottom plate 13 by bolts to ensure the straight running of the cutter rack 17. The floating head 23 is connected to the cutter rack 17 by a torsion spring, so that the floating head 23 can reset itself after being bent sideways. The blade 26 is connected to the floating head 23 by bolts. The side bending seat 24 is connected to the bottom plate 13 by bolts, and the upper part is fitted with the side bending bearing 33.
[0037] The seedling placing mechanism comprises a clamping rod 22, a clamping base 35, a clamping bottom plate 20, a clamping top rod 21, and a clamping baffle 36. A tension spring is provided between the clamping rod 22 and the bottom plate 13 so that the clamping rod 22 has a tendency to fall.
[0038] The clamping film 20 and the clamping baffle 36 are connected by an optical axis screw, and the clamping film 20 is provided with a slot so that the clamping baffle 36 can only rotate in one direction. The clamping base 35 is fixed on the clamping film 20 by screws, and the clamping film 20 is connected to the bottom plate 13 by bolts. The clamping baffle 36 and the clamping film 20 are connected by an optical axis screw. One end of the clamping top rod 21 is connected to the clamping rod 22 by an optical axis screw, and the other end slides in the groove of the clamping film 20. In the initial position, the clamping rod 22 has a tendency to fall, thereby driving the clamping top rod 21 to have a tendency to slide forward in the groove of the clamping film 20, and the groove of the clamping film 20 is a hollow design, and there is a space in the middle for the clamping baffle 36 to rotate. The sliding of the clamping top rod 21 in the groove is blocked by the clamping baffle 36, forming a trigger structure similar to a trigger.
[0039] The working method of the present invention is as follows: first, the variable diameter handle 3 is rotated to push the striker 32 to clamp the branch as the grafting carrier. After pressing the switch, the motor 34 drives the groove cam 8 and the scissor cam 7 to rotate through the main shaft, and the cross-cutting mechanism moves forward. During the forward movement, the scissor cam 7 is in idle rotation. Then, when it reaches the specified position, although the groove cam 8 is still rotating, the cross-cutting mechanism no longer moves, and the scissor cam 7 contacts the sharp end 6 of the blade and pushes it to complete the cross-cutting process. Then the groove cam 8 continues to rotate to drive the cross-cutting mechanism back to the initial position. At the same time, the rotation of the main shaft will drive the crank 9 to rotate, and the motor rack will be pushed forward through the crank slider principle, thereby driving the motor pinion 14 and the motor gear 12 to rotate. The power will be transmitted to the knife gear 17 through the transition gear 15, so that the knife rack 18 moves toward the branch direction, so that the blade 26 below cuts the branch. The side of the floating head 23 is a designed curved surface. When the blade 26 cuts the branch, the curved surface will contact the side bending bearing 33 on the side bending seat 24. Due to the effect of the torsion spring, the floating head 23 will drive the blade 26 to bend outward by 20 degrees. After the blade 26 is bent sideways, the collision piece on the side of the knife rack 18 will hit the clamping block piece 36 of the seedling release mechanism, and the clamping rod 22 will fall under the tension of the tension spring, completing the seedling release process.
[0040] Then remove the entire mechanism and wrap the seedlings and branches with a wrapping machine;
[0041] The above process is a one-way process achieved by a single motor rotating one circle. After completing one grafting, the clamping rod in the seedling placing mechanism needs to be manually reset.
[0042] The handheld electric grafting device of the present invention is an unprecedented electric grafting device on the market. It is specially designed for the grafting of tree-based rootstocks and herbaceous seedlings, and demonstrates extremely high innovation capabilities. In response to the grafting needs of eggplant tree-based rootstocks and herbaceous seedlings, we have successfully filled the gap in mechanized grafting technology in this field and provided a more efficient and accurate solution for agricultural production. The operating procedures of grafting workers have been greatly simplified, and the requirements for grafting skills have been reduced. The previously cumbersome steps of cross-cutting, longitudinal cutting, side bending, and seedling release can now be completed with just one switch action, greatly improving the efficiency of grafting. Through the sophisticated timing distribution design, efficient operation under single-motor drive is achieved. Within one motor turnover cycle, the three originally independent actions of cross-cutting, longitudinal cutting, and seedling release are completed, and the entire process is mechanically automated, ensuring the stability and accuracy of the grafting process.
[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
