DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Depend on Figure 1-6 The present invention discloses a grafting device for green-skinned long eggplant plants, comprising a main body 1, a fixed handle 2 is fixedly connected to one side of the main body 1, a rotatable rotating block 4 is arranged on the side of the main body 1, a first handle 3 is arranged on one side of the fixed handle 2, the first handle 3 is fixedly connected to the rotating block 4, and the first handle 3 is connected to the main body 1 through a rotating shaft, a through groove is provided on the rotating block 4 and the main body 1, and the two through grooves form an annular through hole, a first torsion spring 27 is arranged on the outer sleeve of the rotating shaft, and when the first torsion spring 27 is in a natural state, the rotating block 4 is tightly attached to the main body 1, and a shearing knife 26 is fixedly connected to the inner wall of the through groove of the rotating block 4, because the structure of the branch is thin at the top and thick at the bottom, when the branch is cut, the device can be used upside down, and the shearing knife 26 can also be pressed on the cut surface of the branch when it is used later, so that the blade 6 can cut the cut surface of the branch,

[0029] The main body 1 is provided with a blade 6, which can rotate to a horizontal position. The blade 6 is mounted on a first movable block 7. A second handle 5 is provided below the fixed handle 2. One end of the second handle 5 extends into the main body 1. A rotatable rotating wheel 9 is provided in the main body 1 so that the second handle 5 can rotate. When the second handle 5 rotates, the blade 6 can rotate, and the first movable block 7 can move up and down. When the first movable block 7 moves downward, the first movable block 7 can drive the blade 6 to move downward together to cut the branch. The thin upper and thick lower structure of the branch can also fix the device and the branch together when the blade 6 cuts the branch (the through groove is uniform or the through groove can be set to a structure with a large upper part and a small lower part).

[0030] A support rod 20 that can move forward and backward is also provided in the main body 1. The end of the support rod 20 can be against the side of the branch, and there is a gap between the end of the support rod 20 and the plane where the blade 6 is located. The size of the gap is the distance from the cutting position of the blade 6 to the surface of the branch.

[0031] In order to facilitate the device to cut branches (the blade 6 causes interference when cutting branches), the following technical solution is provided: the rotating wheel 9 is provided with a first tooth surface 17 and a second tooth surface 18, the blade 6 is fixedly connected with a knife shaft, and a rack plate 11 is provided below the blade 6, the rack plate 11 and the end of the blade 6 are meshed with each other, the rack plate 11 extends toward one side of the rotating wheel 9, and the rack plate 11 is meshed with the second tooth surface 18, so that when the rotating wheel 9 rotates, the blade 6 can rotate, and after the blade 6 rotates to a horizontal position, its blade surface faces downward, so that when the blade 6 is downward, it can cut on the cut surface of the branch.

[0032] When the device is in use, in order to prevent the blade 6 from starting the cutting action (moving downward) before it moves to the predetermined position, the following technical solution is provided: a fixed tooth 8 is fixedly connected to the side surface of the first movable block 7, the fixed tooth 8 is meshed with the first tooth surface 17, and when the second handle 5 is in initial rotation, the rack plate 11 is in contact with the second tooth surface 18, while the fixed tooth 8 is separated from the first tooth surface 17, and when the blade 6 is rotated to a horizontal position, the fixed tooth 8 is in contact with the first tooth surface 17.

[0033] Since the blade 6 is rotatably installed in the main body 1, in order to prevent the blade 6 from rotating when it moves downward (for cutting operation), the following technical solution is provided: a second movable block 12 is provided inside the main body 1, and when the blade 6 rotates to a horizontal position, the end of the blade 6 can extend into the second movable block 12, and a clamping block 15 is also provided in the second movable block 12, and the clamping block 15 can extend above the blade 6 to prevent the blade 6 from rotating upward.

[0034] When the blade 6 rotates to the second movable block 12, the block 15 cannot block the blade 6, and when the blade 6 moves downward with the second movable block 12, the block 15 can block it. In order to achieve the above technical purpose, the following technical scheme is provided: a toggle rod 25 is fixedly connected to the main body 1, and a rotatable toggle wheel 24 is provided in the second movable block 12. The toggle wheel 24 and the block 15 are engaged with each other, so that when the second movable block 12 moves downward, the block 15 can move to the top of the blade 6.

[0035] The first movable block 7 and the second movable block 12 are fixed together by a connecting rod 19, so that the two ends of the blade 6 can move up and down synchronously. The connecting rod 19 is arc-shaped to match the through groove. The support rod 20 is fixed to the connecting rod 19. A central shaft 10 is fixed to the axis of the rotating wheel 9, and a worm 22 is installed on the central shaft 10. A mounting block 21 is fixed to the connecting rod 19, and a third tooth surface 23 is provided on the mounting block 21. The third tooth surface 23 cooperates with the worm 22, so that when the worm 22 rotates, the mounting block 21 can drive the connecting rod 19 to slide.

[0036] The sizes of branches are different. In order to ensure that the blade 6 can cut at the appropriate position when cutting the branch in the vertical direction (avoiding the incision position being too close to the middle of the branch or too close to the bark), the blade 6 can slide and a support rod 20 is provided. The support rod 20 is against the side wall of the branch to position the blade 6, thereby ensuring that the incision position is not too close to the middle of the branch or too close to the bark.

[0037] A rotating wheel 9, a first tooth surface 17 and a central axis 10 are also provided on one side of the second movable block 12. The two central axes 10 are connected and driven by a transmission belt to ensure that both ends of the blade 6 can move up and down synchronously.

[0038] A slot is provided on the central axis 10, an insertion rod 28 is fixedly connected to the worm 22, and a second torsion spring 29 is provided outside the insertion rod 28. When the support rod 20 is pressed against the side of the branch, as the rotating wheel 9 continues to rotate, the support rod 20 will no longer be able to move (in order to ensure the integrity of the branch and avoid affecting the grafting). When the support rod 20 is pressed against the side of the branch, the central axis 10 continues to rotate, and the second torsion spring 29 undergoes elastic deformation.

[0039] A spring 14 is provided at the lower end of the first movable block 7 and the second movable block 12, which supports the first movable block 7 and the second movable block 12 on the one hand and resets the first movable block 7 and the second movable block 12 on the other hand. Slide blocks 16 are fixed to the first movable block 7 and the second movable block 12, respectively, and two tracks 13 are respectively provided in the main body 1, thereby limiting the sliding tracks of the first movable block 7 and the second movable block 12.

[0040] A method for using a grafting device for green-skinned long eggplant plants comprises the following steps:

[0041] Step 1: Hold the first handle 3 tightly to put the branch into the through groove. After releasing the first handle 3, the shearing knife 26 can be pressed against the side wall of the branch. By rotating the grafting device, the branch can be cut.

[0042] Step 2: by holding the second handle 5 tightly, the blade 6 can cut the branch from top to bottom. After releasing the second handle 5, the blade 6 is separated from the branch, leaving an incision for grafting on the branch.
