[0034] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] The embodiment of the present invention provides a grafting fixing device and fixing method for peach planting, such as Figure 1-11 As shown, the grafting fixing device for peach planting includes: a grafting fixture used in pairs, the grafting fixture includes a lower arc piece 1 and an upper arc piece 2, the lower arc piece 1 and the upper arc piece 2 cooperate with each other, can be respectively arranged on both sides of the same branch, and are mutually fixed to clamp the grafted branch; soft lining bags 3 are fixedly installed in the lower arc piece 1 and the upper arc piece 2 for tightly fitting and clamping the grafted branch, the two soft lining bags 3 are respectively located on the side where the lower arc piece 1 and the upper arc piece 2 are close to each other, and the two sides where the soft lining bags 3 are close to each other are provided with arc-shaped grooves 4 for fitting with the branch; the soft lining bag 3 has a bag cavity 5, and the bag cavity 5 is filled with a filler 6. When squeezed, the soft lining bag 3 is deformed, and the filler 6 is compressed to cover the grafted branch when clamped; a connecting component is arranged on the lower arc piece 1 and the upper arc piece 2 to form a connection.

[0037] It should be noted that the soft lining bladder 3 of the present embodiment has a meridian structure, which is the same as the structure of a car tire and has a deformable property, but the deformation is limited.

[0038] In this embodiment, it is mainly composed of a grafting fixture used in pairs and a connecting assembly. The grafting fixture includes a lower arc piece 1 and an upper arc piece 2, which cooperate with each other and can be respectively arranged on both sides of the same branch, and ensure the stability of the grafted branch by fixing and tightening the grafted branch. Soft lining capsules 3 are fixedly installed in the lower arc piece 1 and the upper arc piece 2, and these soft lining capsules 3 are used to closely fit and tighten the grafted branch to reduce damage to the branch and improve the fixing effect.

[0039] The design of the soft lining capsules 3 is the key. They are located on the side where the lower arc piece 1 and the upper arc piece 2 are close to each other, and the two soft lining capsules 3 are provided with arc-shaped slots 4 on the side where they are close to each other. These slots fit the branches to provide more stable support. The soft lining capsules 3 are provided with a capsule cavity 5 inside, and the capsule cavity 5 is filled with a filler 6. When squeezed, the soft lining capsules 3 can be deformed, and the filler 6 is compressed, so as to adapt to and tightly cover the grafted branches, ensuring fixation while protecting the branches from damage.

[0040] It is worth noting that the soft lining bladder 3 of the present invention adopts the same meridian structure as the automobile tire structure. This structure gives the soft lining bladder 3 good deformability, enabling it to flexibly adapt to branches of different diameters while keeping the deformation within a certain limit to avoid branch damage caused by excessive compression.

[0041] The connection components are arranged on the lower arc piece 1 and the upper arc piece 2 to firmly connect the two together to form a complete fixing device. When in use, the lower arc piece 1 and the upper arc piece 2 are placed on both sides of the grafted branch and fixed by the connection components, and the soft lining bag 3 will fit the branch tightly and deform, achieving a stable and lossless fixing effect.

[0042] In summary, the grafting and fixing device provided by the present invention has the advantages of simple use method, scientific use principle, strong adaptability, etc. It is particularly suitable for the grafting and fixing of fruit trees such as peaches, and can significantly improve the stability and survival rate of grafting, while protecting branches and trunks from damage.

[0043] In a further preferred embodiment of the present invention, the connecting assembly includes first side plates 7 respectively fixedly mounted on both sides of the upper arc piece 2, and threaded rods 8 are rotatably mounted on the two first side plates 7. Second side plates 9 are fixedly mounted on both sides of the lower arc piece 1, and threaded holes 10 are formed on the two second side plates 9, and the threaded holes 10 are adapted to the threaded rods 8.

[0044] In this embodiment, the connection assembly includes first side plates 7 respectively fixedly mounted on both sides of the upper arc piece 2, and the two first side plates 7 provide a stable mounting base for the threaded rod 8. A threaded rod 8 can be rotatably mounted on each first side plate 7, and this design enables the threaded rod 8 to rotate flexibly, thereby achieving the effect of tightening or loosening.

[0045] At the same time, the second side plates 9 are fixedly installed on both sides of the lower arc piece 1, and the two second side plates 9 are provided with threaded holes 10 adapted to the threaded rods 8. When the grafting fixture needs to be fixed, the upper arc piece 2 and the lower arc piece 1 are placed on both sides of the grafted branch, and then the threaded rod 8 is rotated to pass through the first side plate 7 and screwed into the corresponding threaded holes 10. As the threaded rod 8 is continuously screwed in, the distance between the upper arc piece 2 and the lower arc piece 1 is gradually reduced until the soft lining bag 3 is tightly attached to and clamps the grafted branch.

[0046] The method of using the connection assembly is simple and intuitive, and the tightening effect can be achieved by rotating the threaded rod 8 without complicated operation steps. At the same time, since the threaded rod 8 and the threaded hole 10 are tightly and stably matched, it can ensure that the grafting fixture remains fixed for a long time and is not easy to loosen or fall off.

[0047] The present invention uses the principle of threaded connection to achieve a tightening effect by utilizing the friction between the threaded rod 8 and the threaded hole 10. When the threaded rod 8 is screwed into the threaded hole 10, the friction between the two gradually increases until a sufficient tightening force is reached, thereby ensuring the stability and reliability of the grafting fixture.

[0048] The connection assembly provided by the present invention is ingeniously designed, simple in structure, easy to operate and reliable in fastening. The threaded rod 8 can be quickly fixed and loosened, which greatly improves the efficiency of the grafting operation. At the same time, the design of the soft lining bag 3 reduces the risk of damage to the branches and trunks, and protects the healthy growth of the fruit trees. In addition, the present invention also has wide applicability and good stability, and can meet the grafting fixation requirements under different environments and conditions.

[0049] In a further preferred embodiment of the present invention, a seat block 11 is fixedly installed on the outer side of the lower arc piece 1, and an insertion opening 12 is opened on the seat block 11, and the opening direction of the insertion opening 12 is consistent with the direction of the grafted branches.

[0050] In this embodiment, a seat block 11 is designed on the outer side of the lower arc piece 1, and an insertion opening 12 is opened on the seat block 11 in the same direction as the grafted branch. When fixing the grafting fixture, the user can insert the connecting strip 13 or other fixing parts into the insertion opening 12 of the two seat blocks 11, and fix them with fasteners such as locking bolts 14. Since the opening direction of the insertion opening 12 is consistent with the direction of the grafted branch, the fixing operation is smoother and more accurate, and the stable connection between the grafting fixture and the branch is also ensured.

[0051] The design of the seat block 11 and the insertion opening 12 utilizes the transmission principle of structural mechanics and mechanics, and improves the connection strength and stability between the grafting fixture and the branches by increasing the connection points and optimizing the connection direction. In addition, this design is also convenient for users to quickly install and disassemble, thereby improving work efficiency.

[0052] In a further preferred embodiment of the present invention, a connecting strip 13 is inserted into the insertion opening 12 , and a locking bolt 14 is threadedly mounted on the seat block 11 for abutting and fixing the connecting strip 13 .

[0053] In this embodiment, the connecting strip 13 is cleverly inserted into the insertion opening 12 and fixed by the locking bolt 14 threadedly mounted on the seat block 11. This design not only enhances the stability of the grafting and fixing device, but also improves its convenience and flexibility in use.

[0054] When fixing the grafting fixture, the user first inserts the connecting strip 13 into the insertion openings 12 of the two seat blocks 11, ensuring that the connecting strip 13 is in the same direction as the grafted branch and the position is accurate. Then, by rotating the locking bolt 14, it gradually contacts and tightens the connecting strip 13, thereby achieving a stable connection between the grafting fixtures. The whole process is simple and quick, and does not require complicated tools or operating skills.

[0055] This design utilizes the principle of threaded connection, and generates an inward thrust by rotating the locking bolt 14, so that the connecting strip 13 is firmly fixed in the insertion opening 12. At the same time, the connecting strip 13 acts as a connecting piece to tightly connect the two grafting fixtures together, forming an effective support and fixation for the grafted branches. This design not only improves the stability of the grafting interface, but also reduces the risk of loosening due to external forces.

[0056] In a further preferred embodiment of the present invention, the number of the threaded holes 10 and the number of the threaded rods 8 are both four and are evenly distributed.

[0057] In this embodiment, the design of the threaded hole 10 and the threaded rod 8 is optimized, specifically, the number of both is four, and these components are evenly distributed on the device.

[0058] When fixing the grafting fixture, the user drives the four threaded rods 8 to rotate synchronously by operating the knob device (such as turning the handle or knob). Due to the threaded fit between the threaded rods 8 and the threaded holes 10, the threaded rods 8 will gradually screw into the corresponding threaded holes 10, thereby driving the lower arc piece 1 and the upper arc piece 2 to gradually approach and clamp the branch. Since the four groups of threaded rods 8 and threaded holes 10 are evenly distributed, it is ensured that the grafting fixture can be evenly stressed during the fixing process, avoiding damage to the branch caused by excessive pressure at a single point.

[0059] The design utilizes the principle of threaded transmission, and realizes linear motion of the threaded rod 8 in the threaded hole 10 by rotating the threaded rod 8. The uniform distribution and synchronous rotation of the four groups of threaded rods 8 ensure the stability and balance of the grafting fixture during the fixing process. In addition, the self-locking property of the threaded transmission also ensures that the grafting fixture will not be easily loosened due to external factors after being fixed.

[0060] In a further preferred embodiment of the present invention, a support cover 15 is fixedly installed on the outer top of the upper arc piece 2, and two groups of support shaft seats 16 are fixedly installed on the outer side of the upper arc piece 2, and the two groups of support shaft seats 16 are respectively located on both sides of the support cover 15, and two driving shafts 17 are rotatably installed on the support cover 15, and both ends of the two driving shafts 17 are fixedly installed with active bevel gears 18, and two transmission shafts 19 are rotatably installed on the two groups of support shaft seats 16, and the two ends of the four transmission shafts 19 are respectively fixedly installed with driven bevel gears 1 20 and active bevel gears 2 21, and the four driven bevel gears 1 20 are respectively meshed with the corresponding active bevel gears 1 18, and the tops of the four threaded rods 8 are fixedly installed with driven bevel gears 2 22, and the four driven bevel gears 22 are respectively meshed with the corresponding active bevel gears 2 21.

[0061] In this embodiment, a support cover 15 is added to the top of the outer side of the upper arc piece 2, and support shaft seats 16 are fixed on both sides thereof. Two driving shafts 17 are rotatably installed in the support cover 15, and both ends of each driving shaft 17 are equipped with a driving bevel gear 1 18. At the same time, two transmission shafts 19 are rotatably installed on each of the two groups of support shaft seats 16, and both ends of each transmission shaft 19 are respectively fixed with a driven bevel gear 1 20 and a driving bevel gear 2 21. The four driven bevel gears 1 20 are meshed with the corresponding driving bevel gear 1 18, and the top ends of the four threaded rods 8 are fixed with driven bevel gears 2 22, and these driven bevel gears 2 22 are respectively meshed with the corresponding driving bevel gears 2 21.

[0062] During the grafting operation, the user can rotate the drive shaft 17 by operating it. The rotation of the drive shaft 17 drives the active bevel gear 18 to rotate, and then drives the driven bevel gear 1 20 and the transmission shaft 19 to rotate through the meshing relationship. The rotation of the transmission shaft 19 is then transmitted to the driven bevel gear 2 22 through the active bevel gear 2 21, and finally drives the threaded rod 8 to rotate and move in the threaded hole 10, so as to achieve the clamping or loosening of the upper arc piece 2 and the lower arc piece 1 on the branch.

[0063] The design utilizes the principle of gear transmission, and transmits the rotational power of the drive shaft 17 to the threaded rod 8 through the meshing of multi-stage bevel gears to achieve its linear motion. This transmission method is not only compact in structure and high in transmission efficiency, but also can achieve uniform distribution and transmission of power, ensure the synchronous rotation and movement of the four threaded rods 8, and ensure the stability and balance of the grafting fixture.

[0064] The meshing transmission of the multi-stage bevel gears effectively improves the efficiency and accuracy of power transmission, making the rotation and movement of the threaded rod 8 more stable and reliable.

[0065] The four threaded rods 8 rotate and move synchronously, ensuring that the grafting fixture can be evenly stressed during the fixing process, avoiding damage to branches and trunks caused by excessive pressure at a single point, and improving stability.

[0066] The user only needs to operate the driving shaft 17 to achieve the clamping or loosening of the entire grafting fixture, without having to adjust each threaded rod 8 individually, which greatly improves the convenience and efficiency of the operation.

[0067] This design can be applied to branches of different diameters and shapes. By adjusting the rotation direction and speed of the drive shaft 17, precise control of the clamping force can be achieved to meet diverse grafting needs.

[0068] In a further preferred embodiment of the present invention, a synchronous wheel 23 is fixedly sleeved on each of the two driving shafts 17 , and a same synchronous belt 24 is sleeved on the two synchronous wheels 23 .

[0069] In this embodiment, in order to further enhance the synchronization between the two drive shafts 17 and ensure that they can rotate synchronously, a synchronous wheel 23 is fixedly mounted on both drive shafts 17, and the two synchronous wheels 23 are connected by the same synchronous belt 24.

[0070] When in use, the user only needs to operate one of the drive shafts 17, and the rotation of the drive shaft 17 will drive the synchronous wheel 1 23 thereon to rotate, and then the rotational power will be transmitted to the other synchronous wheel 1 23 through the synchronous belt 1 24, so that the two drive shafts 17 can achieve synchronous rotation. This design simplifies the operation process and improves work efficiency.

[0071] This design utilizes the principle of synchronous belt transmission, and realizes non-slip transmission between the two drive shafts 17 through the cooperation of synchronous wheel 1 23 and synchronous belt 1 24. Synchronous belt 1 24 has good flexibility and wear resistance, and can maintain high transmission accuracy and stability while transmitting power.

[0072] Through the cooperation of the synchronous wheel 23 and the synchronous belt 24, the non-slip transmission between the two drive shafts 17 is realized, the synchronization is improved, and the stability and balance of the grafting fixture are ensured.

[0073] The user only needs to operate one of the driving shafts 17 to achieve the synchronous rotation of the two driving shafts 17, which simplifies the operation process and improves work efficiency.

[0074] In a further preferred embodiment of the present invention, a central shaft 25 is rotatably mounted on the top of the support cover 15, a driving bevel gear three 26 is fixedly mounted on the bottom end of the central shaft 25, a driven bevel gear three 27 is fixedly sleeved on the drive shaft 17 corresponding to the central shaft 25, and the driven bevel gear three 26 is meshed with the driving bevel gear three 27.

[0075] In this embodiment, in order to further optimize the power transmission system, a rotatable middle shaft 25 is added to the top of the support cover 15. A driving bevel gear 3 26 is fixedly mounted on the bottom end of the middle shaft 25, and a driven bevel gear 3 27 is fixedly sleeved on the drive shaft 17 corresponding to the middle shaft 25. The two bevel gears mesh with each other to form a new power transmission path.

[0076] When in use, the user can choose to drive indirectly by rotating the middle shaft 25. When the middle shaft 25 rotates, the active bevel gear 3 26 at its bottom will drive the driven bevel gear 3 27 meshing with it to rotate, thereby transmitting power to the corresponding drive shaft 17. Due to the presence of the synchronous wheel 1 23 and the synchronous belt 1 24, the two drive shafts 17 will keep rotating synchronously, thereby ensuring the coordinated operation of the entire system.

[0077] This design cleverly utilizes the meshing transmission principle of bevel gears, and realizes indirect transmission of power through the cooperation of the bevel gears on the center shaft 25 and the drive shaft 17.

[0078] By introducing the middle shaft 25 and the bevel gear meshing transmission mechanism, users can choose direct or indirect drive mode, which improves the flexibility of the system.

[0079] Even when driven by the center shaft 25, the synchronous wheel 23 and the synchronous belt 24 can ensure the synchronous rotation of the two drive shafts 17, thereby maintaining the overall stability and balance of the system.

[0080] In a further preferred embodiment of the present invention, a protective cover 28 is detachably provided on the outside of the upper arc plate 2 and the two first side plates 7, a knob shaft 29 is rotatably installed on the top of the protective cover 28, the knob shaft 29 is vertically distributed with the center shaft 25, a spline sleeve 30 is fixedly installed on the bottom end of the knob shaft 29, a spline shaft 31 is fixedly installed on the top of the center shaft 25, the spline shaft 31 can engage or disengage with the spline sleeve 30, an operating knob 32 is fixedly installed on the top of the knob shaft 29, a sealing sleeve 33 is rotatably provided on the outside of the operating knob 32, and the sealing sleeve 33 is fixedly connected to the top of the protective cover 28.

[0081] In this embodiment, in order to improve the convenience and safety of the grafting fixture, a protective cover 28 is detachably mounted on the upper arc plate 2 and the two first side plates 7. The protective cover 28 can not only effectively protect the internal mechanical structure from the external environment, but also enhance the user's operating experience through its special design.

[0082] When in use, the user first ensures that the protective cover 28 is properly installed on the outside of the upper arc plate 2 and the two first side plates 7. Then, the knob shaft 29 is rotated by operating the operating knob 32 at the top. The rotation of the knob shaft 29 will drive the spline sleeve 30 at its bottom to rotate. When the spline sleeve 30 engages with the spline shaft 31 at the top of the center shaft 25, the center shaft 25 will also rotate, thereby driving the entire power transmission system to work. When it is necessary to stop or adjust, just rotate the operating knob 32 in the opposite direction to separate the spline sleeve 30 from the spline shaft 31. The design of the sealing sleeve 33 ensures the sealing of the operating knob 32 during the rotation process, preventing dust or moisture from entering the internal mechanical structure.

[0083] This embodiment uses the spline transmission principle to achieve power transmission between the knob shaft 29 and the center shaft 25. The engagement and separation design of the spline sleeve 30 and the spline shaft 31 facilitates maintenance, and the addition of the protective cover 28 and the sealing sleeve 33 further improves the safety and reliability of the system.

[0084] The design of the protective cover 28 effectively prevents the user from accidentally touching the internal mechanical structure, thereby reducing the risk of operation.

[0085] The rotation of the center shaft 25 can be easily controlled by operating the knob 32, thereby achieving the clamping and loosening of the grafting fixture, and the operation is simple and quick.

[0086] The meshing and disengagement design of the spline sleeve 30 and the spline shaft 31 ensures the accuracy and stability of power transmission and facilitates maintenance. At the same time, the addition of the sealing sleeve 33 also improves the sealing and durability of the system.

[0087] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0088] In another embodiment of the present invention, the lower arc piece 1 and the upper arc piece 2 are both provided with a synchronous air pressure balancing mechanism with the corresponding soft lining bag 3, and the synchronous air pressure balancing mechanism includes an air pressure balancing cavity 34 opened on the lower arc piece 1 and the upper arc piece 2, and the lower arc piece 1, the upper arc piece 2 and the two soft lining bags 3 are all provided with connecting holes 35 for connecting the corresponding air pressure balancing cavity 34 and the bag cavity 5.

[0089] In this embodiment, a synchronous air pressure balance mechanism is added to the original design. This innovative design aims to maintain a close fit between the lower arc piece 1, the upper arc piece 2 and the soft lining bag 3 by automatically adjusting the air pressure, thereby improving the stability and success rate of the grafting.

[0090] During use, as the lower arc piece 1 and the upper arc piece 2 gradually approach and clamp the branch, the soft lining bag 3 will deform to adapt to the shape of the branch. At this time, the air in the air pressure balance chamber 34 will exchange with the air in the bag chamber 5 through the connecting hole 35 to achieve air pressure balance. This automatic adjustment mechanism ensures that the soft lining bag 3 can always be close to the surface of the branch and will not be loose or deformed due to air pressure difference.

[0091] The core of the synchronous air pressure balance mechanism lies in the design of the air pressure balance chamber 34 and the connecting hole 35. When the grafting fixture clamps the branch, the soft lining bag 3 is squeezed and the air pressure in the bag cavity 5 increases. At this time, part of the air will flow into the air pressure balance chamber 34 through the connecting hole 35, reducing the pressure in the bag cavity 5 until the internal and external air pressures are balanced. Conversely, when the grafting fixture is released, the air in the air pressure balance chamber 34 will flow back into the bag cavity 5 through the connecting hole 35, ensuring that the soft lining bag 3 can quickly return to its original state.

[0092] The synchronous air pressure balance mechanism can automatically adjust the air pressure to keep the soft lining bag 3 and the branches tightly fitted, thereby improving the stability of the grafting.

[0093] The design enables the grafting fixture to adapt to branches of different shapes and sizes, thereby improving its versatility and practicality.

[0094] By reducing the loosening or deformation of the soft lining bag 3 caused by uneven air pressure, this embodiment can more effectively protect the branches and trunks from damage.

[0095] A stable grafting process can reduce the number of repeated operations and adjustments, thereby improving the overall efficiency of the grafting operation.

[0096] In another embodiment of the present invention, a pair of piston plates 36 can be slidably installed in the two air pressure balance chambers 34, a connecting pull wire 37 is fixedly installed between the pair of piston plates 36, and an operating pull wire 38 is installed through the two communicating holes 35. One end of the operating pull wire 38 located in the air pressure balance chamber 34 is fixedly connected to the connecting pull wire 37, and the other end extends into the bag cavity 5. A support shell 39 is provided in the two bag cavities 5. The operating pull wire 38 can be slidably extended into the support shell 39, and a connecting block 40 is fixedly installed on the outer side of the support shell 39. The connecting block 40 is fixedly connected to the inner wall of the soft lining bag 3 located on the lower arc piece 1 and / or the upper arc piece 2 side. A winding shaft 41 is rotatably installed in the support shell 39 for winding the operating pull wire 38, and two protective rings 42 are fixedly sleeved on the winding shaft 41 for limiting operation. The winding position of the pull wire 38, the support shell 39 is provided with a sliding opening 43 on one side corresponding to the arc-shaped slot 4, and a rack plate 44 is slidably installed in the sliding opening 43, and the soft lining bag 3 is fixedly installed with a connecting plate 45 on the inner wall of one side of the arc-shaped slot 4, and the connecting plate 45 is fixedly connected to the rack plate 44, and one side of the rack plate 44 has a plurality of teeth 46, and a power transmission shaft 47 is rotatably installed in the support shell 39, and a circular gear 48 is fixedly sleeved on the power transmission shaft 47, and the circular gear 48 is meshed with the teeth 46, and a synchronous wheel 2 49 is fixedly sleeved on the winding shaft 41 and the power transmission shaft 47, and the two synchronous wheels 2 49 are sleeved with the same synchronous belt 2 50, and a retractable jacket 51 is fixedly installed between the support shell 39 and the connecting plate 45, and the retractable jacket 51 is located outside the rack plate 44.

[0097] In this embodiment, in order to further enhance the flexibility and precision of the air pressure balancing mechanism, a pair of slidable piston plates 36 are innovatively introduced into the two air pressure balancing chambers 34, and through a series of complex mechanical linkage mechanisms, fine regulation of the air pressure inside the soft lining bag 3 is achieved.

[0098] When in use, the user can control the rotation of the power transmission shaft 47 through an external operating mechanism. The rotation of the power transmission shaft 47 drives the circular gear 48 to rotate. Since the circular gear 48 is meshed with the teeth 46 on the rack plate 44, the rack plate 44 will slide along the sliding opening 43. The sliding of the rack plate 44 drives the inner wall of one side of the soft lining bag 3 to move through the connecting plate 45, thereby changing the volume of the bag cavity 5. At the same time, the movement of the rack plate 44 also drives the piston plate 36 in the air pressure balance chamber 34 to slide through the transmission of the operating pull wire 38 and the connecting pull wire 37, further adjusting the air pressure in the air pressure balance chamber 34. In this process, the synchronous wheel 2 49 and the synchronous belt 2 50 ensure the synchronous rotation of the winding shaft 41 and the power transmission shaft 47, ensuring the coordinated operation of the entire system.

[0099] The core of this embodiment is to achieve fine control of air pressure through a mechanical linkage mechanism. The rotation of the power transmission shaft 47 is the power source of the entire system. It converts the rotational motion into linear motion through the meshing of the circular gear 48 and the rack plate 44, thereby changing the shape of the soft lining bag 3 and the volume of the bag cavity 5. At the same time, the piston plate 36 in the air pressure balance chamber 34 also slides under the traction of the connecting wire 37 and the operating wire 38 to achieve air pressure balance. In the whole process, the synchronous transmission of the synchronous wheel 2 49 and the synchronous belt 2 50 ensures the stability and coordination of the system.

[0100] By finely regulating the air pressure inside the soft lining bag 3, it can be ensured that the grafting fixture maintains a stable pressure and fit when clamping the branches, thereby improving the success rate and quality of the grafting.

[0101] Through the mechanical linkage mechanism, the air pressure inside the soft lining bag 3 is finely regulated, thereby improving the stability and success rate of the grafting.

[0102] The design enables the grafting fixture to adapt to branches of different shapes and sizes, thereby improving its versatility and practicality.

[0103] By finely controlling the air pressure, the risk of branch damage due to uneven pressure is reduced.

[0104] The synchronous transmission effect of the synchronous wheel 2 49 and the synchronous belt 2 50 ensures the stability and coordination of the system and improves the working efficiency and reliability of the entire device.

[0105] In another embodiment of the present invention, the connecting plate 45 is made of elastic metal material, and the connecting plate 45 is an arc-shaped plate.

[0106] In this embodiment, since the connecting plate 45 is made of elastic metal and is designed as an arc-shaped plate, it can be flexibly bent and stretched under the drive of the rack plate 44. This design enables the connecting plate 45 to better adapt to the shape change of the soft lining bag 3 under the change of air pressure, ensuring that the connection between the rack plate 44 and the connecting plate 45 is stable and smooth. When using, the user does not need to perform special operations on the connecting plate 45, and it will automatically adjust according to the working state of the system.

[0107] The arc-shaped plate design of elastic metal material gives the connecting plate 45 good flexibility and adaptability. When the rack plate 44 slides along the sliding port 43 driven by the power transmission shaft 47 and the circular gear 48, the connecting plate 45 can bend and stretch along its motion trajectory, thereby driving the inner wall of the soft lining bag 3 to move and realize the change of the volume of the bag cavity 5. At the same time, the design of the arc-shaped plate also helps to maintain the close fit between the connecting plate 45 and the inner wall of the soft lining bag 3, thereby improving the sealing and stability of the entire system.

[0108] This embodiment is particularly suitable for fruit tree grafting operation scenarios that require high flexibility and adaptability of the mechanical structure. In actual operation, branches of different shapes and sizes may produce different extrusion and deformation effects on the grafting fixture. By using an arc-shaped plate made of elastic metal material as the connecting plate 45, it can be ensured that the grafting fixture can still maintain stable performance and reliable sealing when dealing with these complex situations. Since the connecting plate 45 is made of elastic metal material and is designed as an arc-shaped plate, it can be flexibly bent and stretched under the drive of the rack plate 44. This design enables the connecting plate 45 to better adapt to the shape changes of the soft lining bag 3 under changes in air pressure, ensuring that the connection between the rack plate 44 and the connecting plate 45 is stable and smooth. When using it, the user does not need to perform special operations on the connecting plate 45, it will automatically adjust according to the working status of the system.

[0109] In another embodiment of the present invention, side sealing plates 52 are detachably installed at both side openings of the protective cover 28 , and the side sealing plates 52 cover the sides of the upper arc plate 2 and the two first side plates 7 .

[0110] In this embodiment, in order to further improve the sealing performance and practicality of the protective cover 28 , detachable side sealing plates 52 are designed at the openings on both sides of the protective cover 28 .

[0111] When in use, the user can easily install the side sealing plates 52 to the openings on both sides of the protective cover 28, so that it can tightly cover the sides of the upper arc plate 2 and the two first side plates 7. This design is not only convenient for users to install and disassemble, but also allows the side sealing plates 52 to be removed when not in use, so as to maintain and repair the internal mechanical structure.

[0112] The side sealing plate 52 is connected to the protective cover 28 in a detachable installation manner, ensuring that it can be quickly and firmly fixed to both sides of the protective cover 28 when needed. This design not only ensures the sealing of the protective cover 28 to prevent external impurities from entering the internal mechanical structure, but also facilitates the user to disassemble and install as needed.

[0113] The present invention also provides a method for fixing a grafting fixing device for peach planting, comprising the following steps:

[0114] Step 1: Grafting the peach tree, after the grafting is completed, wrap the grafting position with a film, and then hold the lower arc piece 1 and the upper arc piece 2 respectively, so that they are located at the upper or lower end of the film wrapping, avoiding the incision position;

[0115] Step 2: Make the threaded rod 8 correspond to the threaded hole 10, and turn the operating knob 32. The operating knob 32 drives the knob shaft 29, the spline sleeve 30, the spline shaft 31, the intermediate shaft 25 and the active bevel gear 3 26 to rotate synchronously. When the active bevel gear 3 26 rotates, the driven bevel gear 3 27 that is meshed with each other is driven to mesh with each other. At this time, the corresponding driving shaft 17 rotates synchronously. The two driving shafts 17 use the synchronous wheel 1 23 and the synchronous belt 1 24 to rotate synchronously. When the driving shaft 17 rotates, the active bevel gear 18 drives the meshing driven bevel gear 18. The wheel 1 20 rotates, thereby rotating the transmission shaft 19, and the transmission shaft 19 drives the active bevel gear 2 21 to rotate, and the active bevel gear 2 21 drives the meshing driven bevel gear 2 22 and the threaded rod 8 to rotate, so that the threaded rod 8 is screwed into the threaded hole 10, and the spacing between the lower arc piece 1 and the upper arc piece 2 is controlled, so that the arc-shaped slots 4 of the two soft lining bags 3 correspond to the branches. As the threaded rod 8 is continuously tightened, the soft lining bag 3 produces a wrapping deformation and covers the branches. At the same time, the filler 6 in the bag cavity 5 is compressed, thereby completing the fixation of a grafting fixture;

[0116] Step 3: Another grafting fixture is fixed in the same manner as above. After the fixing is completed, the connecting strip 13 is inserted into the insertion openings 12 of the two seat blocks 11 and fixed with the locking bolts 14. In this way, the grafting fixtures used in pairs form a support for the grafting position of the branch trunk;

[0117] Step 4: When the soft lining bag 3 is deformed, the air flows through the connecting hole 35 and the air pressure balance chamber 34. At the same time, the connecting plate 45 approaches the supporting shell 39, and the rack plate 44 slides along the sliding opening 43 and retracts into the supporting shell 39. At this time, the circular gear 48 is driven to rotate under the action of the teeth 46, and the circular gear 48 drives the power transmission shaft 47 to rotate. The power transmission shaft 47 uses the synchronous wheel 2 49 and the synchronous belt 2 50 to drive the winding shaft 41 to rotate. When the winding shaft 41 rotates, the winding operation wire 38 is reeled in, and the operation wire 38 pulls the connecting wire 37. The connecting wire 37 is used to pull the piston plate 36 to slide along the air pressure balance chamber 34. At this time, the space of the air pressure balance chamber 34 is reduced, squeezing the air, so that the inside is in a high-pressure state, ensuring the stability of the fixed branches;

[0118] Step 5: When dismantling the device, the pressure is restored to balance due to the rebound of the soft lining bag 3 and the filler 6. At this time, the piston plate 36 slides to the two sides of the air pressure balance chamber 34, the air pressure balance chamber 34 has the largest space, and the rack plate 44 is reset.

[0119] In summary, compared with the related art, the present device uses a connecting component which is arranged on the lower arc piece 1 and the upper arc piece 2 to firmly connect the two together to form a complete fixing device. When in use, the lower arc piece 1 and the upper arc piece 2 only need to be placed on both sides of the grafted branch and fixed by the connecting component, and the soft lining bag 3 will fit the branch tightly and deform, achieving a stable and lossless fixing effect.

[0120] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.
