[0050] When placing the rootstock and the scion, the lower end of the cylindrical tube 1 is sleeved on the upper end of the rootstock, and the upper end of the rootstock is abutted against the partition plate 10. Then, the vertical rod 22 is pushed away from the upper end of the cylindrical tube 1, and the scion to be grafted is inserted into the cylindrical tube 1. The lower end of the scion will abut against the upper end of the partition plate 10. Then, release the vertical rod 22, and the horizontal pushing spring 24 will drive the vertical rod 22 to automatically move to the upper end of the cylindrical tube 1. After completing the bevel cutting, the partition plate 10 in the cylindrical tube 1 is taken out, and the second motor 20 is started, so that the second threaded rod 35 drives the lifting plate 21 to move downward. The lifting plate 21 will drive the push block 25 to move downward through the vertical rod 22, and the push block 25 will push the scion towards the rootstock, so that the lower end of the scion is inserted into the V-shaped groove of the rootstock, and the automatic insertion and grafting work of the scion can be completed.

[0051] Embodiment 4:

[0052] Referring to Figures 1 - 3 and Figure 7, which is basically the same as Example 3, and further discloses a specific implementation scheme of the sealing part.

[0054] When in use, the second motor 20 is started, so that the second threaded rod 35 drives the lifting plate 21 to move downward, and the lifting plate 21 will drive the pushing block 25 to move downward through the vertical rod 22. At the same time, the lifting plate 21 will drive the pressing rod 34 to move downward. When the pushing block 25 approaches the lower end of the cylindrical tube 1, the pressing rod 34 will press on the lifting plate 30, and the lifting plate 30 will overcome the elastic force of the lifting spring 31 and move downward. The pull rope 32 will no longer pull the pull rod 28, and the torsion spring will drive the multiple thin rods 27 to rotate in the opposite direction and reset. The ends of the multiple thin rods 27 will move closer to the middle part of the cylindrical tube 1. At this time, the elastic rubber tube 33 is sleeved on the outer wall of the multiple thin rods 27, and the output shaft of the second motor 20 is reversed, and the pressing rod 34 will no longer press on the lifting plate 30. The lifting plate 30 will move downward under the action of the lifting spring 31.

[0059] Step 4: Cut the lower end of the scion into a V-shape with the upper V-shaped blade 8 and cut a V-shaped groove in the upper end of the rootstock with the lower V-shaped blade 7;

[0060] Step 5: Withdraw the partition 10 from the cylindrical tube 1, and then make the second motor 20 drive the push block 25 to move downward;

[0062] When in use, for this automatic grape branch grafting device, start the second motor 20 to make the second threaded rod 35 drive the lifting plate 21 to move downward. The lifting plate 21 will drive the push block 25 to move downward through the vertical rod 22. At the same time, the lifting plate 21 will drive the downward pressure rod 34 to move downward. When the push block 25 approaches the lower port of the cylindrical tube 1, the downward pressure rod 34 will press against the lifting plate 30. The lifting plate 30 will move downward against the elastic force of the lifting spring 31, and the pull rope 32 will no longer pull the pull rod 28. The torsion spring will drive the multiple thin rods 27 to rotate reversely and reset. The ends of the multiple thin rods 27 will approach the middle of the cylindrical tube 1. At this time, slip the elastic rubber tube 33 over the outer walls of the multiple thin rods 27 and reverse the output shaft of the second motor 20. The downward pressure rod 34 will no longer press against the lifting plate 30. The lifting plate 30 will slide upward and reset under the action of the lifting spring 31, thereby pulling the pull rod 28 through the pull rope 32. The multiple thin rods 27 will make the elastic rubber tube 33 in a flared shape, and the preparation work of the elastic rubber tube 33 can be completed;

[0063] The lower end of the cylindrical tube 1 is sleeved on the upper end of the stock, and the upper end of the stock is pressed against the partition 10, and then the vertical rod 22 is pushed away from the upper end of the cylindrical tube 1, and the scion to be grafted is inserted into the cylindrical tube 1, and the lower end of the scion will be pressed against the upper end of the partition 10, and then the vertical rod 22 is released, and the horizontal push spring 24 will drive the vertical rod 22 to automatically move to the upper end of the cylindrical tube 1, and then the first motor 5 is started, and the first threaded rod 13 is conveyed to drive the push plate 6 to move in the direction of the cylindrical tube 1, and the push plate 6 will drive the upper V-shaped blade 8 and the lower V-shaped blade 7 to insert into the upper cutting hole 3 and the lower cutting hole 4, and the upper V-shaped blade 8 will cut the lower end of the scion into a V shape, and the lower V-shaped blade 7 will cut a V-shaped groove on the upper end of the stock, so that the cutting angle of the stock and the scion can be automatically completed, so that the grafting efficiency is greatly improved, and then the first motor 5 is reversed, so that the upper V-shaped blade 8 and the lower V-shaped blade 7 can be reversed and reset;

[0064] After completing the angle cutting, the partition 10 in the cylindrical tube 1 is pulled out, and then the second motor 20 drives the push block 25 to move downward, and the push block 25 will push the scion toward the rootstock, so that the lower end of the scion is inserted into the V-shaped groove of the rootstock, and the automatic tightening and grafting work of the scion can be completed. When it is fully inserted, the push block 25 that continues to move downward will make the cylindrical tube 1 move downward. When the push block 25 is about to expose the lower end of the cylindrical tube 1, the ends of multiple thin rods 27 will approach each other, so that the trumpet-shaped elastic rubber tube 33 will elastically reset and shrink, and the lower end of the elastic rubber tube 33 will shrink first, and will slide downward and wrap around the outer wall of the lower end of the rootstock. When the push block 25 will completely separate the scion from the lower end of the cylindrical tube 1, the elastic rubber tube 33 will just be wrapped around the joint between the rootstock and the scion, thereby automatically completing the sealing work of the grafting, which can greatly improve the grafting efficiency of the grape branches.
