It includes multiple ground support rods laid horizontally on the ground along the direction of plant growth inclination; multiple connecting rods positioned between adjacent ground support rods along their length; and multiple anchoring nails fixed to the underside of each ground support rod along its length. The support rods are positioned between the ground support and the plant trunk, and an elastic traction element is vertically positioned between the support rods and the ground support.

Description

Technical Field

[0001] This invention belongs to the field of plant cultivation technology, specifically relating to a cultivation device and method for the protection of rare plants. Background Technology

[0002] With the impact of human activities such as urbanization, agricultural expansion, and environmental pollution, many plants face habitat loss and survival pressures, and may become extinct in their natural environment. Cultivating rare plants can not only help restore or preserve these species, thus protecting biodiversity, but also has significant value in plant science research and resource development. Furthermore, these rare plants have high cultural and economic value as ornamental horticultural plants, such as the Lushan rhododendron, the thousand-year-old ginkgo, and the golden larch.

[0003] When cultivating rare plants, due to the scarcity and preciousness of their seeds, cuttings are typically collected and propagated collectively. Once the cuttings reach a certain height and become seedlings, they are then transplanted individually. Because seedlings have a weaker ability to absorb nutrients and compete with surrounding plants for light, they are usually transplanted at a certain distance from mature plants to ensure they receive sufficient sunlight and nutrients, thus increasing the success rate of rare plant cultivation. However, in such environments, the relatively open surroundings result in poor wind resistance for the seedlings. Furthermore, in the early stages of transplanting, the seedlings' roots are not fully embedded in the deep soil. In the event of strong winds or other severe weather, the seedlings are prone to tipping over, root damage, and other issues, leading to stunted growth, wilting, or even death.

[0004] To improve the survival rate of transplanted seedlings of rare plants, protective supports are typically erected around them. Multiple support poles are distributed on the outside of the seedling's main stem, with one end inserted into the soil and the other end joined together and tied to the main stem to enhance the seedling's resistance to lodging. However, after a period of cultivation, the main stem of these rare plants still tends to tilt. While this tilting may not significantly impact normal growth, it is crucial for the aesthetic appeal of rare plants cultivated in botanical gardens. For example, in the case of Lushan rhododendron, a tilted main stem leads to asymmetrical plant shape, affecting flower distribution and opening, resulting in an uneven distribution and impacting overall beauty. Current field investigations into the tilting problem in rare plant cultivation have revealed several contributing factors, including: the influence of sunlight, terrain, and wind direction in the area. Additionally, uneven application of support force to the main stem during the construction of the multiple support poles can also cause the main stem to tilt to one side and fail to maintain verticality.

[0005] Currently, existing technologies for addressing the issue of tilted main stem growth in rare plants often employ traction ropes for straightening. Specifically, one end of the rope is connected to the plant, and the other end is fixed to the side opposite to the tilting direction of the main stem. By gradually shortening the rope, the plant's main stem is slowly guided from the tilt to a vertical position, resulting in a more balanced and symmetrical mature plant. However, when straightening the plant's main stem by shortening the rope, the amount of shortening relies solely on the operator's experience. Since different plant root systems have varying degrees of penetration into the soil, excessive traction can cause the plant's roots and soil to flip up towards the side of the rope, leading to root rot and irreversible damage to the plant. This makes the process of straightening rare plants during cultivation quite unsafe. Summary of the Invention

[0006] In view of this, the present invention provides a cultivation device and method for the protection of rare plants, in order to overcome the shortcomings of the prior art. The present invention can straighten the main stem of a plant that is growing at an angle and press down the soil on the side of the plant's main stem that is tilted, thereby improving the stability of the plant roots.

[0007] The technical solution of this invention is: a cultivation device for the protection of rare plants, configured and installed between the main stem of a plant growing at an angle and the ground, comprising multiple ground support rods laid horizontally on the ground along the direction of the plant's growth angle, with the multiple ground support rods located on the side of the plant leaning towards the ground; multiple connecting rods arranged between adjacent ground support rods along the length direction of the ground support rods, with both ends of the connecting rods fixedly connected to the ground support rods to form a ground support frame; and multiple anchor nails fixed to the lower side of each ground support rod along the length direction of the ground support rod, the anchor nails being inserted into the soil to fix the ground support frame and provide support. The support rod is positioned between the ground support and the plant trunk. One end of the support rod is hinged to the ground support rod on the side away from the plant trunk, and the other end abuts against the plant trunk. An elastic traction element is vertically positioned between the support rod and the ground support. One end of the elastic traction element is connected to the ground support rod on the side of the ground support closer to the plant trunk, and the other end is connected to the support rod on the side closer to the plant trunk. This applies a downward pulling force to the support rod, causing it to exert a force on the plant trunk in the opposite direction of its tilt, thus supporting the tilted plant. The reaction force of the plant trunk on the support rod presses the ground support downward.

[0008] Preferably, it also includes: a clamp and a guide ring. The clamp is fitted onto the main stem of the plant and is located on the side of the main stem closest to the ground. The guide ring is vertically set on the side of the clamp close to the support rod. The guide ring is connected to the clamp, and the elastic traction element passes through the guide ring.

[0009] Preferably, a guide pulley is horizontally arranged on the inner side of the guide ring, and the guide pulley is rotatably connected to the guide ring around its circumference, with an elastic traction member wrapped around the guide pulley.

[0010] Preferably, the angle α between the elastic traction member above the guide ring and the vertical direction is in the range of 20° to 35°, and the angle β between the elastic traction member below the guide ring and the horizontal plane is in the range of 15° to 30°.

[0011] Preferably, it also includes: a lead screw, an internal threaded ring, and a connecting pipe. One end of the lead screw is fixedly connected to the guide ring. The internal threaded ring is sleeved on the lead screw and is threadedly connected to it. One end of the connecting pipe is fixedly connected to the clamp. The lead screw extends into the interior of the connecting pipe from the other end. The center line of the lead screw and the connecting pipe are coaxial. The end of the internal threaded ring away from the guide ring is rotatably connected to the connecting pipe.

[0012] Preferably, the ground support rods are arc-shaped, the plant stem is located inside the multiple ground support rods, the center lines of the multiple ground support rods and the center line of the plant stem are located in the same vertical plane, and each ground support rod is fitted with an installation ring, which is slidably connected to the ground support rod in the circumferential and length directions. The end of the support rod away from the plant stem and the end of the elastic traction member away from the support rod are respectively connected to the corresponding installation ring.

[0013] Preferably, a connecting ring is fitted onto the ground support rod, and arc-shaped grooves are respectively opened on the inner and outer sides of the ground support rod along its circumference. Two sliders are fixed on the inner wall of the connecting ring, and the sliders slide along the arc-shaped grooves. The connecting ring is detachably and fixedly connected to the ground support rod by fasteners. The mounting ring is fitted onto the connecting ring and is coaxial with its center line. The mounting ring rotates around its circumference and is connected to the connecting ring.

[0014] Preferably, an arc-shaped plate is vertically provided at the end of the support rod away from the ground. The center line of the arc-shaped plate is perpendicular to the ground support rod. The outer side of the arc-shaped plate is hinged to the support rod. Multiple first rotating shafts are horizontally provided at equal intervals along the center line of the inner side of the arc-shaped plate. The two ends of the first rotating shafts are rotatably connected to the arc-shaped plate. An elastic buffer tube is fixedly fitted on the first rotating shaft and abuts against the main stem of the plant.

[0015] Preferably, the outer diameter of the elastic buffer tube gradually decreases from both ends toward the middle.

[0016] A method of using a cultivation device for the protection of rare plants includes the following steps:

[0017] Clean and level the ground on the side of the plant's main stem that is leaning, and place the ground support on the cleaned and leveled ground.

[0018] Adjust the position of the ground support according to the tilt direction of the plant trunk, so that the support rod is tilted and facing the plant trunk. Rotate the support rod to one side of the plant trunk to make it abut against it, and then tap the ground support rod downward to make the anchor nail insert into the soil to fix the ground support.

[0019] Connect the end of the elastic traction component away from the support rod to the ground support rod on the side of the ground support closest to the plant trunk. This allows the support rod to apply a force to the plant trunk in the opposite direction of its tilt, thus straightening the tilted plant trunk.

[0020] Compared with existing technologies, the present invention provides a cultivation device and method for the protection of rare plants. A ground support structure is formed by interconnecting multiple ground support rods and connecting rods. The ground support is fixed in the soil using multiple anchor nails. Support rods, in conjunction with an elastic traction component, are used. One end of the support rod is hinged to the ground support rod on the side of the ground support away from the plant's main stem, while the other end abuts against the tilted main stem of the plant. The elastic traction component applies a downward pulling force to the support rod, causing it to exert a force on the plant's main stem opposite to its tilt direction, thus straightening the tilted plant's main stem. Furthermore, the elastic traction component itself has a certain degree of expansion and contraction buffering, preventing excessive force on the plant's main stem when straightening it. The reaction force of the plant's main stem presses the ground support downward, causing the ground support to hold the soil on the tilted side of the plant's main stem, improving the stability of the plant's roots and preventing root uprooting during straightening, thereby enhancing the safety of straightening rare plants during cultivation.

[0028] This invention provides an encapsulation claw for SPD varistor electronic components, which is described below in conjunction with... Figures 1 to 7 The present invention is illustrated by the structural diagram shown below.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] Reference Figure 1 , Figure 1 This is a front view of the cultivation and protection device of this embodiment. A cultivation device for the protection of rare plants is configured and installed between the main stem of a plant growing at an angle and the ground. It includes multiple ground support rods 1 laid horizontally on the ground along the direction of the plant's growth angle, with the multiple ground support rods 1 located on the side of the plant leaning towards the ground. Multiple connecting rods 2 are arranged between adjacent ground support rods 1 along their length direction. The two ends of the connecting rods 2 are fixedly connected to the ground support rods 1 to form a ground support frame. Multiple anchor nails 3 are fixed to the underside of each ground support rod 1 along its length direction, and the anchor nails 3 are inserted into the soil to fix the ground support frame. Support rod 4 is installed between the ground support and the plant trunk. One end of support rod 4 is hinged to the ground support rod 1 on the side away from the plant trunk, and the other end abuts against the plant trunk. Elastic traction member 5 is vertically installed between support rod 4 and the ground support. One end of elastic traction member 5 is connected to the ground support rod 1 on the side of the ground support closer to the plant trunk, and the other end is connected to the side of support rod 4 closer to the plant trunk, so as to apply a downward pulling force to support rod 4, so that support rod 4 applies a force to the plant trunk in the opposite direction of its tilt, thus supporting the plant that is growing at an angle. The reaction force of the plant trunk on support rod 4 presses the ground support downward.

[0031] This embodiment presents a cultivation device for the protection of rare plants. It achieves safe and gradual straightening of the plant's main stem by combining a stable ground support system with a flexible traction mechanism. The device includes a ground support frame consisting of ground support rods 1 and connecting rods 2, as well as support rods 4 and elastic traction components 5 positioned between the ground support frame and the plant's main stem. The overall structure is rationally laid out, with all components working collaboratively to provide effective thrust while enhancing the stability of the root region through mechanical feedback.

[0032] Specifically, the ground support rods 1 are laid horizontally at equal intervals along the direction of plant growth inclination, and the ground support rods 1 are perpendicular to the direction of plant growth inclination. The connecting rods 2 are arranged at equal intervals along the length of the ground support rods 1, and the anchoring nails 3 are arranged at equal intervals along the length of the ground support rods 1.

[0033] The ground support rod 1 can be made of high-strength metal materials such as Q235 steel or aluminum alloy. Its cross-sectional shape can be circular, rectangular, or polygonal, and its length is adjusted according to the actual plant size and inclination, generally within the range of 1.0m to 2.5m. Connecting rods 2 are equidistantly installed between adjacent ground support rods 1 along their length, forming a grid-like or frame-like ground support structure. This structure not only improves lateral stiffness and prevents deformation of the support due to local settlement, but also distributes concentrated loads to a larger area of ​​soil, improving the overall stability of the device. Anchor nails 3 are fixedly installed at equal intervals along the lower side of each ground support rod 1. Their structure can be tapered steel nails, spiral nails, or forked inserts, capable of penetrating deep into the stable soil layer. After the entire ground support is in place, the anchor nails 3 are fully embedded in the soil by hammering or mechanical pressing, achieving reliable anchoring of the ground support. Support rod 4 is positioned between the ground support and the plant trunk. One end of it is hinged to the ground support rod 1 on the side furthest from the plant trunk, allowing the support rod to rotate freely around the hinge point. The other end directly abuts against the surface of the plant trunk. Elastic traction element 5 is vertically arranged between support rod 4 and the ground support. Its upper end connects to the side of support rod 4 closest to the plant trunk, and its lower end connects to the ground support rod 1 on the same side. This elastic traction element 5 can be an elastic traction component, a rubber cable, or a highly elastic synthetic fiber rope, capable of generating a controllable restoring force under stress. When the device is in use, the elastic traction element 5 applies a continuous downward pulling force to support rod 4, causing the support rod to rotate downward around the hinge point, thereby pushing the plant trunk to swing in the opposite direction of its original tilt, achieving a slow and stable straightening process.

[0034] It is worth noting that the plant trunk generates a corresponding reaction force while receiving the pushing force. This force is transmitted to the ground support through the support rod 4 and finally to the deep soil through the anchor nail 3. This process not only corrects the posture of the trunk but also simultaneously compacts the surface soil of the root zone, enhances the bond between the roots and the surrounding medium, and significantly reduces the risk of root damage.

[0035] This embodiment realizes a plant protection and cultivation device that combines active correction and passive reinforcement functions. Because it uses an elastic traction component 5 as the power source for straightening, its output straightening force has a slow-release and adaptive nature, avoiding tissue tearing or root breakage caused by instantaneous loading. Simultaneously, the ground support presses the soil downwards while bearing the reaction force, effectively achieving "self-reinforcement" while correcting, thus improving the overall stability of the system. Therefore, this device is particularly suitable for non-invasive, low-damage directional straightening operations on rare plants that are sensitive to their growing environment and have weak resistance to interference.

[0036] Reference Figure 5 , Figure 5 This is a BB cross-sectional view of the cultivation protection device in this embodiment. As a further optimization, this embodiment also includes: a clamp 6 and a guide ring 7. The clamp 6 is fitted on the plant stem and is located on the side of the plant stem closer to the ground. The guide ring 7 is vertically arranged on the side of the clamp 6 closer to the support rod 4. The guide ring 7 is connected to the clamp 6, and the elastic traction member 5 passes through the guide ring 7.

[0037] This embodiment achieves spatial position constraint and force path guidance for the elastic traction member 5 by introducing a combined structure of clamp 6 and guide ring 7. Clamp 6 serves as the installation base, fixed to the area near the ground on the plant trunk to support subsequent functional components. Guide ring 7 is fixedly connected to the side of clamp 6 facing the support rod 4 and extends vertically to form a limiting channel for the elastic traction member 5 to pass through. When the elastic traction member 5 passes through the guide ring 7, its movement trajectory is effectively limited within a preset spatial range, preventing lateral deviation or swaying during the stretching process.

[0038] The clamp 6 can be made of metal or high-strength engineering plastic, possessing a certain degree of elasticity and clamping capacity to adapt to plant trunk surfaces of different diameters. Its inner wall can be lined with a flexible padding layer, such as rubber or silicone, to increase friction and prevent mechanical damage to the bark. The clamp 6 can be assembled in an openable manner using a fastening bolt structure, facilitating quick on-site installation and disassembly. The guide ring 7 is a rigid annular component with a through hole at its center. Its axis is perpendicular or substantially perpendicular to the ground, ensuring that the elastic traction component 5 maintains a stable vertical force transmission path during movement. The inner diameter of the guide ring 7 is slightly larger than the outer diameter of the elastic traction component 5, allowing for smooth sliding while limiting excessive swaying.

[0039] After passing through the guide ring 7, the elastic traction component 5 is distributed in two sections during operation. The upper section connects to the side of the support rod 4 closest to the plant stem, and the lower section connects to the ground support rod 1 in the ground support system, also close to the plant stem. Due to the presence of the guide ring 7, the elastic traction component 5 maintains a relatively ideal geometric orientation even under stress and deformation, significantly reducing lateral forces caused by abrupt angle changes, thereby improving force transmission efficiency. Furthermore, this structure reduces unintended contact between the elastic traction component 5 and other components, lowering the risk of wear and extending its service life.

[0040] The aforementioned components form a hierarchical support relationship. The clamp 6, attached to the plant trunk, provides an installation reference. The guide ring 7, relying on the clamp 6, establishes spatial positioning. The elastic traction component 5, with the help of the guide ring 7, guides the traction path. This step-by-step transmission structural design not only enhances the overall coordination of the system but also improves the adaptability of the device in complex environments.

[0041] This embodiment achieves effective guiding control of the elastic traction component 5. During plant straightening, the elastic traction component 5 needs to continuously apply downward tension to drive the support rod 4 to generate a reverse corrective force on the tilted trunk. Without effective path constraints, the traction component is prone to deviating from the predetermined plane, leading to uneven force distribution, localized stress concentration, or even slippage failure. However, by setting the clamp 6 and guide ring 7, the elastic traction component 5 always transmits tension along the set direction, improving the stability and controllability of force transmission. Simultaneously, it reduces frictional losses during dynamic use, thereby enhancing the long-term reliability and safety of the device.

[0042] In this embodiment, when the reaction during the process of straightening the plant trunk causes the ground support to slide away from the plant trunk, the clamp 6 and guide ring 7 can pull the lower section of the elastic traction member 5, reducing the amount of slippage of the ground support. Furthermore, when the ground support slides, the tension of the elastic traction member 5 is increased, which increases the downward force exerted by the elastic traction member 5 on the support rod 4, thereby improving the straightening force on the plant trunk.

[0043] As a further optimization, in this embodiment, a guide pulley 8 is horizontally arranged on the inner side of the guide ring 7. The guide pulley 8 is rotatably connected to the guide ring 7 around its circumference, and the elastic traction member 5 is wound around the guide pulley 8.

[0044] In this embodiment, the elastic traction member 5 passes through the outer circumference of the guide pulley 8 in a winding manner, that is, it enters from one side of the guide ring 7, passes over the top of the guide pulley 8, and then exits to the connecting end of the support rod 4. Since the guide pulley 8 is movable, when the elastic traction member 5 is displaced or its tension is adjusted due to changes in the force on the support rod 4, the guide pulley 8 rotates synchronously, converting the original sliding friction between the elastic traction member and the fixed guide structure into rolling friction, significantly reducing running resistance.

[0045] Specifically, in this embodiment, the center line of the guide pulley 8 is parallel to the ground support rod 1. The groove of the guide pulley 8 can be designed as V-shaped or arc-shaped to adapt to elastic traction members 5 with different cross-sectional shapes, improve contact stability, and prevent derailment.

[0046] In this embodiment, the components form the following cooperative relationship: the guide ring 7 provides the installation foundation and spatial positioning for the entire guide mechanism, and restricts the lateral displacement of the elastic traction member 5; the guide pulley 8 realizes dynamic rolling guidance inside it, and the two together form an efficient and low-resistance force transmission channel, so that the elastic traction member 5 can still flexibly respond to the angle change of the support rod 4 and the small displacement of the plant trunk while bearing continuous tension.

[0047] Reference Figure 6 , Figure 6 The image shown is a CC cross-sectional view of the cultivation protection device in this embodiment. As a further optimization, in this embodiment, the elastic traction member 5 located above the guide ring 7 has an angle α between itself and the vertical direction ranging from 20° to 35°, and the elastic traction member 5 located below the guide ring 7 has an angle β between itself and the horizontal plane ranging from 15° to 30°.

[0048] In this embodiment, the force distribution of the elastic traction component 5 is optimized by limiting its orientation angle in space. The elastic traction component 5, as a key component for transmitting tension, directly affects the direction and magnitude of the straightening force exerted by the support rod 4 on the plant trunk. Angle α refers to the angle between the elastic traction component 5 above the guide ring 7 and the vertical direction; this angle controls the intensity of the downward vertical force component. Angle β refers to the angle between the elastic traction component 5 below the guide ring 7 and the horizontal plane, affecting the horizontal traction component. Setting α between 20° and 35° ensures that the elastic traction component 5 above the guide ring 7 has a sufficiently large downward vertical tension component, effectively driving the support rod 4 to generate a reverse thrust on the plant trunk, achieving a stable and continuous straightening effect. Simultaneously, it avoids the risk of lateral instability of the ground support due to either an excessively small α causing limited overall device height and installation difficulties, or an excessively large α resulting in an excessively high proportion of lateral force. By controlling β within the range of 15° to 30°, it is possible to ensure that the elastic traction member 5 located below the guide ring 7 has a certain horizontal tensile component, which prevents the ground support from sliding away from the main stem of the plant due to the support rod 4. The vertical component ensures that the elastic traction member 5 can maintain a reasonable tension posture after passing around the guide ring 7, which is conducive to the smooth transmission of force and improves the reliability of system operation.

[0049] In this embodiment, the two angle parameters mentioned above work together to determine the spatial geometric path and mechanical behavior of the elastic traction component 5. When the elastic traction component 5 passes through the guide ring 7, its direction changes. The upper section mainly provides vertical tension, while the lower section needs to provide resistance to the slippage of the ground support and maintain an appropriate preload angle to meet connection requirements. By rationally configuring the angle combination of α and β, the optimal force distribution effect can be achieved under different terrain conditions and plant inclination, giving the device good environmental adaptability and adjustment flexibility.

[0050] In this implementation, the spatial arrangement angle of the elastic traction component 5 is scientifically limited. By controlling the range of the included angles α and β, the elastic traction component 5 can generate a dominant downward pulling force to drive the straightening action in actual work, while maintaining the overall mechanical balance and structural stability of the system. Therefore, it achieves the technical effects of optimizing the force performance, improving the straightening efficiency and enhancing the applicability of the device.

[0051] In this embodiment, when the tilt angle of the plant trunk is large, it is recommended that α be 35° and β be 15°. This ensures that the angle α between the elastic traction member 5 above the guide ring 7 and the vertical direction is maximized, providing sufficient downward vertical tension while also having a certain horizontal component. This ensures that the support rod 4 always abuts against the plant trunk to straighten it. Because the tilt angle of the vertical trunk is large, the horizontal force transmitted to the ground support through the support rod 4 is also large. The angle β between the elastic traction member 5 below the guide ring 7 and the horizontal plane is 15°, making the elastic traction member 5 below the guide ring 7 nearly horizontal. This provides sufficient traction to prevent the ground support from slipping, ensuring the stability of the overall device. Conversely, when the tilt angle of the plant trunk is small, α is selected as 20° and β as 30°. This straightens the plant trunk while reducing the deformation of the elastic traction member 5, thus increasing its service life.

[0052] Reference Figure 3 , Figure 7 , Figure 3 This is a schematic diagram showing the connection between the clamp and the guide ring in this embodiment. Figure 3 This is an enlarged schematic diagram of point D of the cultivation protection device in this embodiment. As a further optimization, this embodiment also includes: a lead screw 9, an internal threaded ring 10, and a connecting pipe 11. One end of the lead screw 9 is fixedly connected to the guide ring 7. The internal threaded ring 10 is sleeved on the lead screw 9 and threadedly connected to it. One end of the connecting pipe 11 is fixedly connected to the clamp 6. The lead screw 9 extends into the interior of the connecting pipe 11 from the other end. The center lines of the lead screw 9 and the connecting pipe 11 are coaxial. The end of the internal threaded ring 10 away from the guide ring 7 is rotatably connected to the connecting pipe 11.

[0053] This embodiment provides a screw fine-tuning mechanism for adjusting the preload of an elastic traction component. Through the coordinated configuration of the lead screw 9, the internal threaded ring 10, and the connecting pipe 11, continuous and controllable adjustment of the tension applied to the support rod by the traction system is achieved. This structure is particularly suitable for the straightening process of rare plants with different growth states, tilt angles, or trunk diameters. It can flexibly adapt to changes in on-site working conditions without replacing components, thereby improving the operating accuracy and applicability of the device.

[0054] In this system, the lead screw 9 serves as the transmission and displacement output element. One end is rigidly connected to the guide ring 7, ensuring that the position of the guide ring changes synchronously with the axial movement of the lead screw. The other end of the lead screw 9 is inserted into the connecting pipe 11 and remains coaxial with the center line of the connecting pipe 11 to ensure stability and alignment during movement. One end of the connecting pipe 11 is fixedly connected to the clamp 6, which is installed around the near-ground end of the plant trunk, making the foundation anchor point of the entire adjustment mechanism rely on the plant body to form a stable force-bearing support. The internal threaded ring 10 is fitted around the outer circumference of the lead screw 9 and forms a helical pair with it, that is, the internal thread of the internal threaded ring 10 meshes with the external thread of the lead screw 9, constituting a mechanical transmission unit that can convert rotary motion into linear motion.

[0055] Furthermore, the end of the internal threaded ring 10 furthest from the guide ring 7 is rotatably connected to the connecting pipe 11. This rotatable connection can be achieved by setting a bushing structure, namely, an annular groove is provided at the end of the internal threaded ring 10 furthest from the clamp 6, and an annular step is provided on the inner wall of the side of the internal threaded ring 10 furthest from the guide ring 7. The annular step allows the internal threaded ring 10 to be fitted onto the annular groove and rotatably connected to it. The purpose is to restrict the axial displacement of the internal threaded ring 10 while allowing it to rotate freely around its own axis. Therefore, when the operator manually or with a tool rotates the internal threaded ring 10, since it is constrained on the connecting pipe 11 and cannot move axially, the screw 9 will generate a relative displacement along the axial direction under the action of the thread—if rotated clockwise, the screw 9 will extend outward, driving the guide ring 7 to move away from the clamp 6; conversely, it will retract. This axial displacement directly changes the installation distance between the two ends of the elastic traction member 5, thereby adjusting its initial tension.

[0056] For example, in practical applications, when it is necessary to increase the straightening force on the tilted trunk, the screw 9 can be gradually extended by rotating the internal threaded ring 10, pushing the guide ring 7 forward, thereby tightening the elastic traction member 5, increasing the downward pull on the support rod 4, and ultimately increasing the reverse thrust of the support rod on the plant trunk. Conversely, if the plant is in the early stage of recovery and requires a smaller corrective force, or if the original tension is too large due to growth, the internal threaded ring 10 can be rotated in the opposite direction to increase the effective length of the screw outside the connecting pipe 11, releasing some of the traction force to achieve flexible adjustment.

[0057] In this embodiment, the thread length of the lead screw 9 can be designed to be 50mm to 150mm according to the typical adjustment stroke, and the pitch is 2mm to 6mm, so as to balance adjustment accuracy and efficiency. The connecting pipe 11 can be a round tubular metal component with an inner diameter slightly larger than the outer diameter of the lead screw to ensure smooth lead screw movement; its connection with the clamp 6 can be welded or bolted. The outer surface of the internal threaded ring 10 can be provided with knurling, a handle, a wrench interface, or a ring handwheel structure can be installed on the outside of the internal threaded ring 10 to facilitate the rotation of the internal threaded ring 10.

[0058] In this embodiment, the assembly relationship between the components ensures the independence and reliability of the adjustment action. The clamp 6 and the connecting pipe 11 form a static reference, the internal threaded ring 10 only rotates, and the lead screw 9 completes the axial feed. The three have a clear division of labor and a clear mechanical transmission path. This structure not only avoids the stress concentration problem caused by directly stretching the elastic element, but also realizes the stepless adjustment function, significantly improving the engineering applicability of the device.

[0059] This embodiment achieves precise control of the tension of the elastic traction component 5. Because a screw drive adjustment mechanism consisting of a lead screw 9, an internal threaded ring 10, and a connecting pipe 11 is set up, the lead screw 9 can be driven to move axially by rotating the internal threaded ring 10, thereby changing the position of the guide ring 7 and changing the force-bearing length of the elastic traction component 5. The magnitude of the straightening force can be dynamically adjusted without interrupting the operation. This solves the problem that traditional fixed traction structures are difficult to adapt to the individual differences and growth dynamics of different plants, and achieves the technical effect of improving the versatility, safety and adjustment accuracy of the device.

[0060] As a further optimization, in this embodiment, the ground support rod 1 is arc-shaped, the plant trunk is located inside the multiple ground support rods 1, the center line of the multiple ground support rods 1 and the center line of the plant trunk are located in the same vertical plane, and the ground support rod 1 is respectively fitted with an installation ring 12, which is slidably connected to the ground support rod 1 in the circumferential and length directions. The end of the support rod 4 away from the plant trunk and the end of the elastic traction member 5 away from the support rod 4 are respectively connected to the corresponding installation ring 12.

[0061] This embodiment provides a ground support system with optimized structural layout. By designing the ground support rods as arcs and using adjustable mounting rings, it achieves spatial adaptation and multi-point coordinated support for tilted plant trunks. This structure enhances the adaptability of the device in complex terrain or irregular tree shapes, while allowing for flexible on-site adjustment of the support and traction points, thus improving the controllability and uniformity of the straightening process.

[0062] The ground support pole 1 is made of metal tubing or high-strength composite material with certain rigidity and bending resistance. It has an overall arc-shaped structure, and its curvature is designed according to the natural tilting trend of the trunk of a typical rare plant. This allows multiple ground support poles, distributed along the tilting direction of the plant trunk, to form an arc-shaped array facing the plant trunk. The plant trunk is located in the inner space of this arc-shaped array, thus ensuring good symmetry and stability of the entire ground support system under stress.

[0063] Multiple ground support poles 1 are laid horizontally on the ground at equal intervals along the inclined direction of the plant trunk, with their extension direction perpendicular to the inclined direction of the trunk, forming a lateral load-bearing unit. The support poles are fixedly connected by connecting rods 2 to form a stable ground support frame. This support not only bears the reaction force transmitted from the support poles 4, but also serves as the anchoring foundation for the elastic traction element 5, participating in the overall mechanical balance.

[0064] In this embodiment, a mounting ring 12 is fitted onto the ground support rod 1, allowing it to slide freely in both directions on the support rod surface—it can move axially along the ground support rod 1 and rotate around it. This dual-degree-of-freedom connection method allows the mounting ring 12 to be positioned arbitrarily on the arc-shaped support rod, thereby realizing the spatial reconstruction of the connection point between the support rod 4 and the elastic traction element 5. The mounting ring 12 is typically made of wear-resistant engineering plastic or lightweight metal alloy, possessing a certain coefficient of friction to prevent self-slippage. If necessary, its position can be locked by adding a locking screw or elastic clamp.

[0065] The end of the support rod 4 furthest from the plant trunk is hinged to a mounting ring 12, while the end of the elastic traction member 5 furthest from the support rod 4 is also connected to the mounting ring 12. These two connection points can be independently adjusted according to the actual tilt angle and height difference of the plant trunk. For example, when the plant trunk is slightly tilted, the hinge point of the support rod 4 can be set on the side furthest from the plant trunk, while the connection point of the elastic traction member 5 can be set on the side closer to the plant trunk to obtain a more reasonable lever arm ratio and improve the straightening efficiency. Conversely, when the tilt is large, the hinge point of the support rod 4 can be set on the side furthest from the plant trunk, while the connection point of the elastic traction member 5 can be set on the ground support rod 1 located between the hinge point of the support rod 4 and the plant trunk on the side furthest from the plant trunk.

[0066] Furthermore, the sliding fit between the mounting ring 12 and the ground support rod 1 allows the device to adapt to non-standard symmetrical tilting shapes, such as when the main stem is S-shaped or has local deflection. By adjusting the position of each mounting ring 12 on the arc-shaped support rod, multi-point distributed support can be achieved, avoiding stress concentration at a single contact point and reducing the risk of mechanical damage to the plant epidermis.

[0067] In this embodiment, the ground support rod 1 adopts an arc-shaped layout and is equipped with an installation ring 12 that can slide freely in the circumferential and axial directions. This allows the connection position of the support rod 4 and the elastic traction member 5 to be dynamically adjusted according to the specific tilt state of the plant trunk. This solves the problem that traditional straight support structures are difficult to fit irregular tree shapes and have uneven distribution of support force. As a result, the device's versatility and adaptability to different types of rare plants are improved, and the stability and safety during the straightening process are enhanced.

[0068] Specifically, in this embodiment, a screw 19 is provided radially on the outer side of each connecting ring 13, and a threaded countersunk hole is provided at the end of the support rod 4 away from the plant trunk. The support rod 4 is detachably connected to the screw 19 through the threaded countersunk hole. By using the connecting ring 13, screw 19 and support rod 4 together, not only can the support rod 4 be rotatably connected to the ground support rod 1, but the support rod and screw can also be quickly disassembled. This allows the operator to flexibly adjust the position of the support rod according to the straightening situation, move the support rod to the side of the plant, increase the straightening force on the plant trunk, and improve the straightening effect of the plant's tilted growth.

[0069] The support rod 4 is fitted with a second U-shaped connecting seat 22 at one end away from the ground support rod 1. The support rod 4 abuts against the inner side of the second U-shaped connecting seat 22. A third rotating shaft 23 is horizontally provided on the inner side of the second U-shaped connecting seat 22. The two ends of the third rotating shaft 23 are rotatably connected to the second U-shaped connecting seat 22. A screw 19 is also provided on the outer side of the third rotating shaft 23 and is perpendicular to its central axis. The two ends of the elastic traction member 5 are respectively provided with internal threaded tubes 24. The internal threaded tubes 24 and the screw 19 are detachably fixedly connected. By using the second U-shaped connecting seat, the third rotating shaft and the internal threaded tubes in combination, the elastic traction member can be disassembled and installed or adjusted and then quickly reconnected when adjusting the position of the support rod or installing this equipment.

[0070] On the side of the support rod 4 away from the ground support rod 1, multiple through holes 25 are horizontally and evenly spaced along the central axis of the support rod 4. The through holes 25 are parallel to the third rotating shaft 23. A limiting post 26 is horizontally inserted on the second U-shaped connecting seat 22. The limiting post 26 passes through the through hole 25 and is slidably connected to it. By using the through holes and the limiting post in combination, the connection position between the two ends of the elastic traction member and the support rod and the ground support rod can be flexibly adjusted.

[0071] Reference Figure 4 , Figure 4The diagram shows a cross-sectional view of the cultivation protection device in this embodiment. As a further optimization, a connecting ring 13 is fitted onto the ground support rod 1 in this embodiment. Arc-shaped grooves 14 are respectively opened on the inner and outer sides of the ground support rod 1 along its circumference. Two sliders 15 are fixed on the inner wall of the connecting ring 13. The sliders 15 slide along the arc-shaped grooves 14. The connecting ring 13 is detachably and fixedly connected to the ground support rod 1 by fasteners. The mounting ring 12 is fitted onto the connecting ring 13 and is coaxial with its center line. The mounting ring 12 is rotatably connected to the connecting ring 13 around its circumference.

[0072] This embodiment provides a technical solution for improving the stability of the installation structure while maintaining adjustment flexibility. By adding a connecting ring 13 with a slider 15 to the ground support rod 1, and cooperating with the arc-shaped sliding groove 14 provided on the support rod body, the position of the connecting ring 13 relative to the ground support rod 1 is adjustable. After the position is adjusted, the connecting ring 13 is locked to the ground support rod 1 by fasteners, forming a stable and reliable connection base. On this basis, the mounting ring 12 is fitted onto the outside of the connecting ring 13, and forms a circumferential rotational connection with it, so that the support rod 4 or elastic traction member 5 installed on it can rotate freely according to the direction of force, adapting to dynamic load changes.

[0073] The ground support rod 1, serving as the main load-bearing component of the entire ground support system, has symmetrically formed arc-shaped grooves 14 on its surface along the circumferential direction on both the inner and outer sides. These grooves extend in an arc. The cross-sectional shape of the arc-shaped grooves 14 can be designed as T-shaped, dovetail-shaped, or rectangular to ensure the guiding accuracy and anti-disengagement capability of the slider 15 after insertion. The grooves can be directly milled onto the metal ground support rod 1 through machining, or they can be integrally formed into the composite material rod body using a mold.

[0074] The connecting ring 13 is a ring-shaped structural component, sleeved around the outer periphery of the ground support rod 1. Two sliders 15 are fixedly installed on its inner wall, symmetrically arranged and embedded in the arc-shaped grooves 14 on the inner and outer sides of the ground support rod 1, forming a double-track guide structure to effectively prevent the connecting ring 13 from twisting or deviating during sliding. The sliders 15 can be made of wear-resistant engineering plastics such as polyoxymethylene (POM) or metal materials such as stainless steel, and their shape matches the arc-shaped grooves 14 to ensure smooth sliding and controllable clearance. The sliders 15 can be fixed to the inner wall of the connecting ring 13 with screws, possessing sufficient connection strength to transmit the push and pull forces during adjustment.

[0075] The connecting ring 13 is detachably and fixedly connected to the ground support rod 1 via fasteners. The fasteners can be quick-release pins, clamp-type locking mechanisms, etc. Typically, a through hole is provided at one end of the connecting ring 13, which mates with a threaded hole passing through the wall of the ground support rod 1. After screwing in a screw, the connecting ring 13 is pressed together to generate a radial clamping force, thereby locking it in its current position. This structure ensures both the continuity and freedom of adjustment during the adjustment process, and provides a high-strength mechanical lock after adjustment, preventing loosening due to vibration or long-term stress.

[0076] Mounting ring 12 is another annular component, fitted around the outer circumference of connecting ring 13, with its center line strictly coaxial with connecting ring 13 to ensure the alignment of force transmission. A rotating pair structure is provided between mounting ring 12 and connecting ring 13, such as a rolling bearing, oil-impregnated bushing, or low-friction bushing, allowing mounting ring 12 to rotate freely around the axis of connecting ring 13.

[0077] In this embodiment, there is a clear hierarchical assembly relationship between the components: the ground support rod 1 serves as the basic load-bearing structure, providing an arc-shaped slide 14 as a guide rail; the connecting ring 13 adjusts its position by sliding along the slide 15 with the help of a slider 15, and locks its position with fasteners; the mounting ring 12 serves as the end interface component, integrated on the connecting ring 13, providing a rotatable mounting platform. This layered design balances the degree of freedom of adjustment with structural rigidity, solving the problems of stress concentration and difficulty in adapting to complex terrain caused by traditional fixed installation.

[0078] Specifically, in this embodiment, the arc-shaped groove 14 on the ground support rod 1 works in conjunction with the slider 15 on the connecting ring 13 and the mounting ring 12 to enable the ground support rod 1 to surround the outside of the plant. The support rod 4 slides on the same ground support rod 1 using the slider 15. When straightening, the straightening direction of the support rod 4 can be flexibly adjusted according to the tilt direction of the plant. At the same time, the connecting ring 13 can be fixed by threaded fasteners during straightening to prevent the position of the support rod from changing during straightening, thereby improving the flexibility and stability of plant growth straightening.

[0079] This embodiment significantly enhances the overall rigidity and connection reliability of the installation structure while retaining the adjustability of the installation position. Because the connecting ring 13 can slide within the arc-shaped groove 14 via the slider 15 and is ultimately locked by fasteners, the spatial positioning of the mounting ring 12 is more precise and stable. Simultaneously, the rotatable nature of the mounting ring 12 relative to the connecting ring 13 allows it to adapt to directional changes in the support rod 4 and the elastic traction component 5 during operation, reducing local stress peaks and extending service life. This structure is particularly suitable for applications requiring long-term stable support and where the force direction may dynamically change in rare plant protection scenarios, improving the adaptability and safety of the cultivation device.

[0080] Reference Figure 2 , Figure 2 This is a top view of the cultivation and protection device in this embodiment. As a further optimization, in this embodiment, an arc-shaped plate 16 is vertically provided at the end of the support rod 4 away from the ground support rod 1. The center line of the arc-shaped plate 16 is perpendicular to the ground support rod 1. The outer side of the arc-shaped plate 16 is hinged to the support rod 4. Multiple first rotating shafts 17 are horizontally provided at equal intervals along the center line direction on the inner side of the arc-shaped plate 16. The two ends of the first rotating shafts 17 are rotatably connected to the arc-shaped plate 16. An elastic buffer tube 18 is fitted and fixed on the first rotating shaft 17. The elastic buffer tube 18 abuts against the main stem of the plant.

[0081] This embodiment achieves flexible support for the tilted plant trunk by setting an arc-shaped plate structure with multiple elastic buffer tubes at the top of the support rod. This structure can effectively disperse the pressure at the support point, avoiding bark damage or growth inhibition caused by localized concentrated force. At the same time, the use of elastic materials and a rotatable design reduces the risk of friction damage, improving the gentleness and sustainability of the protective effect.

[0082] The curved plate 16 is a vertically mounted arc-shaped component on the end of the support rod 4 furthest from the ground. Its curvature is designed based on the outer diameter range of the trunks of common rare plants, adapting to trunks with diameters from 10cm to 30cm to ensure a good fit. The centerline of the curved plate 16 is perpendicular to the ground support rod 1, meaning its extension direction is orthogonal to the lateral layout of the ground support, thus causing its concave surface to face the plant trunk, forming a natural enveloping shape. The outer side of the curved plate 16 is connected to the support rod 4 via a hinge, allowing it to swing around the hinge axis within a certain angle range, adapting to contact posture adjustments at different tilt angles and improving installation adaptability.

[0083] Specifically, a first U-shaped connecting seat 20 is horizontally provided on the outer side of the arc plate 16. The bottom of the first U-shaped connecting seat 20 is fixedly connected to the arc plate 16. A second rotating shaft 21 is horizontally provided on the inner side of the first U-shaped connecting seat 20. Both ends of the second rotating shaft 21 are rotatably connected to the first U-shaped connecting seat 20. The end of the support rod 4 away from the ground support rod 1 is fixedly connected to the second rotating shaft 21. Through the cooperation of the first U-shaped connecting seat, the second rotating shaft, the support rod, and the arc plate, when the support rod drives the arc plate to move downward, the arc plate is always in contact with the trunk of the plant.

[0084] Multiple first rotating shafts 17 are arranged horizontally at equal intervals along the centerline of the inner side of the arc-shaped plate 16. These shafts are parallel to the ground and spaced apart, with their arrangement direction aligned with the centerline of the arc-shaped plate. The two ends of each first rotating shaft 17 are rotatably connected to the side walls of the arc-shaped plate 16, for example, by means of bearings or sleeve structures embedded in pre-drilled mounting holes in the side walls, allowing the shaft to rotate freely along its axis. This design enables each first rotating shaft 17 to have independent circumferential rotation capability, providing a dynamic response basis for the subsequently installed elastic buffer tube 18. The first rotating shafts 17 themselves can be made of stainless steel or engineering plastics, possessing sufficient bending strength and corrosion resistance, suitable for long-term outdoor use.

[0085] An elastic buffer tube 18 is fitted and fixed on the first rotating shaft 17. The buffer tube and the rotating shaft are circumferentially fixed using methods such as interference fit, bonding, or clamp locking to prevent relative slippage, while the buffer tube itself can still rotate synchronously with the rotating shaft. The elastic buffer tube 18 is cylindrical or other conformal structure, and its material can be rubber, silicone, or thermoplastic elastomer TPE, possessing good resilience and wear resistance. When the support rod 4 pushes the arc-shaped plate 16 into contact with the plant trunk, multiple elastic buffer tubes 18 together form a flexible contact band extending circumferentially along the trunk, transforming the originally point-like or line-like concentrated pressure into a multi-point distributed load, significantly reducing the pressure per unit area and preventing bark tissue from being crushed and necrotic. Furthermore, under dynamic loads such as wind vibration or human disturbance, the elastic buffer tube 18 can absorb impact energy through deformation, reducing the mechanical stress transmitted to the plant trunk.

[0086] Because the first rotating shaft 17 supports the free rotation of the elastic buffer tube 18, when the plant trunk undergoes slight displacement due to growth or external factors, the buffer tube can roll instead of sliding, greatly reducing the coefficient of friction with the bark and avoiding scratches or girdling effects. This is particularly suitable for rare tree species with thin bark or weak regeneration ability. The equidistant arrangement of multiple buffer tubes also ensures uniform force distribution and prevents excessive local pressure. The spacing between adjacent first rotating shafts 17 is flexibly set according to the actual trunk diameter, controlled between 5cm and 15cm, ensuring sufficient support density without causing structural redundancy.

[0087] In addition, in this embodiment, the two ends of the first rotating shaft 17 are rotatably connected to the arc plate 16 through ratchet pawls. The ratchet pawls cause the first rotating shaft and the arc plate to rotate in one direction, so that the support rod fixes the trunk of the plant and prevents the main trunk of the plant from tilting again when there is strong wind outside.

[0088] This embodiment achieves uniform pressure distribution by using an arc-shaped plate structure with multiple rotatable elastic buffer tubes to expand the contact area between the support component and the trunk during the application of a straightening force to the trunk of a leaning plant. The buffering properties of the elastic material effectively absorb vibration impacts. Furthermore, the rolling mechanism of the buffer tubes driven by the rotating shaft significantly reduces frictional damage caused by relative motion. Therefore, this structure solves the technical problems of traditional rigid supports that easily cause bark damage, wear, and even hinder growth, achieving a gentle, safe, and long-lasting support effect, and is especially suitable for rare plant individuals sensitive to mechanical damage.

[0089] As a further optimization, in this embodiment, the outer diameter of the elastic buffer tube 18 gradually decreases from both ends toward the middle.

[0090] This embodiment further optimizes the contact state between the supporting component and the plant trunk. The elastic buffer tube 18, as a functional element that directly contacts the surface of the plant trunk, is designed with a variable cross-section structure—that is, along the axial direction, the outer diameter continuously decreases from both ends to the middle, presenting an overall profile that is narrower in the middle and raised at both ends. This structure allows the concave middle section of the buffer tube to smoothly transition and fit the curved surface of the trunk when deformed under pressure, while the thicker areas at both ends have higher compressive stiffness and bear the main supporting load.

[0091] The elastic buffer tube 18 can be made of materials with good resilience and biocompatibility, such as rubber, silicone or thermoplastic elastomer TPE, with a Shore hardness between 40A and 70A, to balance support strength and buffering effect.

[0092] In this embodiment, the elastic buffer tube 18 maintains a constant inner diameter to ensure that it can be stably fitted onto the first rotating shaft 17 and fixed by interference fit or bonding; while only the outer diameter is designed with a gradient, which facilitates processing and does not affect assembly stability. Alternatively, the buffer tube can be designed as a segmented assembly structure, consisting of multiple short tubes with different outer diameters connected in sequence. Although this sacrifices some continuity, it is beneficial for replacing damaged units and reducing manufacturing costs.

[0093] This embodiment achieves the effect of the elastic buffer tube 18 adopting a variable cross-section design with the outer diameter gradually decreasing from both ends to the middle, so that when it is in contact with the plant trunk and subjected to pressure, an axial pressure gradient distribution is formed, avoiding the phenomenon of edge stress concentration. This solves the technical problem that traditional support structures are prone to bark compression damage, thereby achieving the technical effects of improving contact safety, preventing tissue necrosis, and enhancing long-term reliability.

[0094] A method of using a cultivation device for the protection of rare plants includes the following steps:

[0095] Clean and level the ground on the side of the plant's main stem that is leaning, and place the ground support on the cleaned and leveled ground.

[0096] Adjust the position of the ground support according to the tilt direction of the plant trunk, so that the support rod 4 is tilted and facing the plant trunk. Rotate the support rod 4 to the side of the plant trunk to make contact with it, and then tap the ground support rod 1 downward to make the anchor nail 3 inserted into the soil to fix the ground support.

[0097] Connect the end of the elastic traction member 5 away from the support rod 4 to the ground support rod 1 on the side of the ground support closer to the plant trunk, so that the support rod 4 applies a force to the plant trunk in the opposite direction of its tilt, thus straightening the tilted plant trunk.

[0098] The method described in this embodiment achieves safe and controllable straightening of the leaning trunk of rare plants through a series of orderly operations. The entire process revolves around the installation and operating mechanism of the device, aiming to establish a stable external support system with continuous adjustment capabilities, gradually correcting the plant's growth posture without causing mechanical damage.

[0099] First, the surface area on the side of the plant's main stem that slopes towards the ground needs to be cleared and leveled. This step aims to remove weeds, stones, or other obstacles and ensure the local terrain is relatively level, thus providing a foundation for the stable placement of the subsequent ground supports. If the ground has a significant slope or loose soil, the topsoil can be removed and the subsoil compacted to enhance anchoring reliability.

[0100] Next, the integrated ground support system, consisting of multiple ground support rods 1, connecting rods 2, and anchor nails 3, is transported to the leveled area and initially placed in position. The ground support system has a grid structure, and its laying direction should be perpendicular to the tilt direction of the plant's main stem, with the entire system positioned on the side where the plant tends to lean, in order to form an effective counter-resistance system.

[0101] Subsequently, based on the observed tilt of the plant trunk, the spatial position of the ground support was fine-tuned to match its layout with the plant's morphology. The key was to ensure that the extension direction of support rod 4 was aligned with the tilt axis of the trunk, guaranteeing that subsequent support forces were transmitted along a reasonable path. After the position was calibrated, support rod 4 was rotated around its hinge point with ground support rod 1 towards the plant trunk until its free end made surface or line contact with the trunk surface.

[0102] After the support rod 4 is connected to the plant trunk, the ground support rod 1 is struck downwards by external force, causing the multiple anchor nails 3 fixed on its lower side to gradually embed into the deep soil layer. This process should preferably be carried out by hammering to ensure that the anchoring depth is sufficient and evenly distributed, so that the entire ground support is firmly anchored in the foundation and has sufficient pull-out and anti-slip capabilities.

[0103] Finally, one end of the elastic traction element 5 is connected to the side of the support rod 4 near the plant trunk, and the other end is fixed to the ground support rod 1 located near the plant trunk on the ground support, forming a vertically arranged tension transmission link. As the elastic traction element 5 is stretched and preloaded, it applies a downward pulling force to the support rod 4, which is then converted into a horizontal pushing force on the plant trunk through the lever principle, in the opposite direction to the original tilting trend. This force is not applied instantaneously, but is slowly released by relying on the continuous retraction characteristics of the elastic element, achieving gradual correction and effectively reducing the risk of impact on the roots and xylem.

[0104] The above steps are performed sequentially and logically, making it easy for on-site personnel to operate according to procedures. Of particular note is the design sequence of first physically securing the ground support before connecting the elastic traction component 5. This helps prevent the device from becoming unbalanced or displaced due to sudden loading in an unstable state, thus improving operational safety.

[0105] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
