Description

Technical Field

[0001] This utility model relates to the field of gardening tools, and in particular to a peony branch fixing clamp. Background Technology

[0002] Grafting is a common propagation method in the cultivation and planting of peonies. Peony grafting involves attaching a scion with superior varietal characteristics to a rootstock, allowing the two to grow together and thus producing high-quality, high-yielding peony plants. However, many problems exist in actual grafting operations.

[0003] Currently, common methods for fixing peony branches have certain limitations. One common method is using tape, but tape (especially plastic tape) creates a closed environment, leading to excessive humidity at the graft union and potentially causing mold or bacteria growth, increasing the risk of infection. For example, if rainy season or prolonged damp weather occurs after grafting, the tape cannot effectively drain water, easily causing the graft union to rot. Another method uses simple hemp rope binding, which, while not creating a closed environment, is more cumbersome. Some methods use fixing clamps, but these clamps have a relatively fixed structure, making it difficult to adjust flexibly to different peony branches and adapt to different sizes of scions and rootstocks. This results in weak clamping, making the graft union susceptible to displacement or loosening during the healing process due to external factors, thus reducing the grafting success rate.

[0004] Given the shortcomings of existing technologies in fixing peony branches, there is an urgent need for a clamp that can stably fix peony branches, adapt to different specifications, be easy to operate, and effectively improve the grafting success rate. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a peony branch fixing clamp.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] A peony branch fixing clamp, comprising:

[0008] Connecting rod;

[0009] The first screw is perpendicularly connected to the connecting rod;

[0010] An adjustable clamping mechanism is adjustablely connected to the connecting rod; the adjustable clamping mechanism includes:

[0011] An adjusting nut is rotatably connected to a connecting rod, and the connecting rod has an opening for accommodating the adjusting nut at the position corresponding to the adjusting nut, and a through hole at the position corresponding to the screw hole of the adjusting nut;

[0012] The second screw is threadedly connected to the adjusting nut.

[0013] Each of the first and second screws has a clamp mounted on one end; the clamp comprises:

[0014] Two grippers are hinged together in a cross configuration, and the cross configuration is hinged to either the first screw or the second screw.

[0015] Two springs are installed at the shanks of the two grippers to keep the two grippers symmetrical about the first screw or the second screw and to maintain a clamped state.

[0016] Preferably, the first screw extends through the connecting rod, and the first screw body is threaded with a locking nut for fixing it to the connecting rod.

[0017] Preferably, the first screw is located at one end of the connecting rod near the end, and the connecting rod has a spherical cavity at that end, with a slot extending through the spherical cavity; a ball head is universally connected inside the spherical cavity, and one end of the ball head is connected to an extension rod; the extension rod has multiple adjustable clamping mechanisms spaced apart; the ball head is locked by a locking nut.

[0018] Preferably, the locking nut is a wing nut that can be turned by hand.

[0019] Preferably, the end of the first screw with the clamp is provided with a hexagonal prism.

[0020] Preferably, the width of the jaws on the first screw is greater than the width of the jaws on the second screw.

[0021] Preferably, the spring is detachably connected to the gripper handle.

[0022] Preferably, a rubber pad is provided on the inner side of the gripper end of the gripper.

[0023] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0024] This utility model has a simple structure. Through the coordinated operation of components such as the connecting rod, the first screw, the adjustable clamping mechanism, and the clamp, it can firmly fix peony branches and prevent them from shaking, thereby improving the grafting success rate. The connecting rod provides a solid foundation support for the entire clamp, while the first and second screws clamp and fix the peony branches from different positions. The design of the claws and springs in the clamp ensures that the clamping force is evenly distributed, guaranteeing the stability of the clamp and avoiding damage to the branches due to excessive clamping force.

[0025] The adjustable clamping mechanism of this invention features an adjusting nut and a second screw, allowing users to flexibly adjust the clamp position according to actual needs. By rotating the adjusting nut, the extension length of the second screw can be precisely controlled, thereby changing the clamp position to accommodate peony branches of different lengths and thicknesses. Furthermore, the detachable connection design between the first screw and the connecting rod, along with the butterfly design of the locking nut, allows users to quickly and easily replace the first screw, improving the clamp's versatility and practicality.

[0026] This invention can adapt to peony branches with different growth directions and degrees of curvature. By incorporating a spherical cavity, a ball head, and an extension rod, users can easily adjust the angle between the connecting rod and the extension rod, thereby changing the growth direction of the peony branches to meet the needs of horticultural styling. This omnidirectional adjustment function expands the applicability of the clamp, making it suitable for various complex horticultural scenarios.

[0027] The rubber pads on the inner side of the grippers in this invention effectively reduce damage to peony branches during clamping, lowering the risk of pinching and promoting healthy branch growth and wound healing. Meanwhile, the detachable connection between the spring and the grippers allows users to replace the spring with one of appropriate elasticity based on the thickness of different branches, further improving the gripper's adaptability and protective capabilities for various branches.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0037] Example 1:

[0038] Referring to Figures 1, 2, and 4, a peony branch fixing clamp includes a connecting rod 1, a first screw 2, an adjustable clamping mechanism, and a clamp 5. The connecting rod 1 tightly connects the first screw 2 to the adjustable clamping mechanism, forming the basic frame of the entire clamp. The connecting rod 1 and the first screw 2 are connected perpendicularly, a design that ensures the stability and firmness of the entire clamp during use. On the connecting rod 1, corresponding to one side of the first screw 2, one or more adjustable clamping mechanisms are provided. These mechanisms can be flexibly adjusted according to actual needs to accommodate peony branches of different sizes.

[0039] The adjustable clamping mechanism mainly consists of an adjusting nut 3 and a second screw 4. An opening is specifically designed on the connecting rod 1 for the adjustable clamping mechanism, and the adjusting nut 3 is rotatably mounted inside this opening, allowing it to rotate freely within the opening. Simultaneously, a through hole is provided on the connecting rod 1 corresponding to the threaded hole of the adjusting nut 3. The second screw 4 can smoothly pass through this through hole and form a threaded connection with the adjusting nut 3. By rotating the adjusting nut 3, the extension length of the second screw 4 can be precisely controlled, thereby achieving fine-tuning of its position.

[0040] Both the first screw 2 and the second screw 4 are equipped with a clip 5 at one end. The clip 5 consists of two jaws 5-1 and two springs 5-2, as shown in the attached figure. Figure 2 As shown, the two grippers 5-1 are connected by a cross-hinged joint, with their intersection hinged to either the first screw 2 or the second screw 4. This ingenious structural design allows the grippers 5-1 to open and close, thus clamping or releasing the peony branches. Two springs 5-2 are installed on the handles of the two grippers 5-1. These springs 5-2 provide a stable clamping force to the grippers 5-1, ensuring a tight grip on the peony branches and preventing unnecessary deflection of the grippers 5 on the first screw 2 or the second screw 4. The springs 5-2 are installed between the first screw 2 or the second screw 4 and the handle of the corresponding gripper 5-1. This arrangement ensures that the elastic force of the springs 5-2 is utilized to the maximum extent, thereby improving the stability of the clamping.

[0041] It is particularly important to emphasize that the width of the clamp 5-1 on the first screw 2 is designed to be larger than that on the second screw 4. This design difference stems from a thorough consideration of practical application scenarios. Since the clamp 5-1 on the first screw 2 is primarily used to secure the scion of the peony graft, the larger width provides a wider contact area, thereby more effectively securing the scion and ensuring the stability of the grafted area during the healing process, preventing displacement or loosening due to external forces.

[0042] In practical applications, the operator first uses the clamp 5 on the first screw 2 to firmly fix the peony scion onto the rootstock. This step requires ensuring the clamping force is moderate, preventing the scion from slipping without damaging it. Next, the extension length of the second screw 4 is adjusted by rotating the adjusting nut 3, thereby changing the position of the clamp 5 on the second screw 4 to precisely clamp the scion. During this process, the connecting rod 1 provides solid support for the scion, preventing it from swaying due to external factors such as wind or impact, thus effectively improving the grafting success rate.

[0043] Example 2:

[0044] Referring to Figures 1 to 5, this embodiment further optimizes and improves the peony branch fixing clamp based on Embodiment 1. Specifically, the first screw 2 passes through the connecting rod 1 in a movable through-hole manner, and a locking nut 6 is threadedly connected to the body of the first screw 2. The main function of the locking nut 6 is to firmly fix the first screw 2 to a designated position on the connecting rod 1; at the same time, this threaded connection method allows for a detachable connection between the first screw 2 and the connecting rod 1. The advantage of this design is that when the first screw 2 wears out or needs to be replaced with a screw of a different specification, the user can easily disassemble and replace it without the need for complex repair or replacement of the entire clamp, greatly improving the practicality and economy of the clamp.

[0045] Furthermore, to facilitate user operation, the end of the first screw 2 where the clamp 5 is mounted is designed in a hexagonal prism shape. This hexagonal prism design not only increases the connection stability between the screw and the clamp 5, but also provides a more convenient tool contact surface for the user when installing or removing the clamp 5. The locking nut 6 is a wing nut that can be directly turned by hand. Wing nuts are known for their unique shape and ease of operation; users can easily tighten or loosen the locking nut 6 using only their fingers without any tools. This design allows users to quickly install or remove the first screw 2 during grafting operations, thereby significantly improving work efficiency.

[0046] In the field of horticulture, adjusting the growth direction of peony branches is an important means of shaping the peony plant and enhancing its ornamental value. To meet this need, the peony branch fixing clamp in this embodiment is specially designed with the function of adjusting the curvature of the peony branches, thereby achieving effective control over the growth direction of the peony branches. Specifically, the first screw 2 is cleverly positioned near the end of one end of the connecting rod 1. At this end of the connecting rod 1, a spherical cavity is constructed inside, and a slot is opened through the spherical cavity. A ball head 7 is installed inside the spherical cavity in a universal joint manner, and one end of the ball head 7 is firmly connected to the extension rod 8. The extension rod 8 has multiple adjustable clamping mechanisms arranged at certain intervals. These adjustable clamping mechanisms work together with the adjustable clamping mechanisms on the connecting rod 1 to achieve multi-point fixing and directional adjustment of the peony branches. By locking the ball head 7 with the locking nut 6, the angle between the extension rod 8 and the connecting rod 1 can be fixed at any desired position.

[0047] In practice, users can first loosen the locking nut 6, and then clamp the clips 5 on the connecting rod 1 and the extension rod 8 onto the peony branch that needs adjustment. Next, users can flexibly adjust the angle between the connecting rod 1 and the extension rod 8 according to the pre-planned plant shape design, thereby achieving precise control over the growth direction of the peony branch. Once the desired position is achieved, the locking nut 6 is tightened to fix the angle between the extension rod 8 and the connecting rod 1, ensuring that the peony branch grows in the set direction. This design is not only flexible and convenient to adjust, but also has a large adjustment range, meeting different styling needs and greatly enhancing the ornamental value of the peony.

[0048] Example 3:

[0049] Referring to Figure 1 to Figure 2 As shown, based on Embodiment 1 or Embodiment 2, this embodiment further optimizes and improves the peony branch fixing clamp. One important improvement is the detachable connection between the spring 5-2 and the claw 5-1. This detachable connection design gives the clamp greater adaptability and flexibility. In practical applications, the robustness of peony rootstocks and scions varies depending on factors such as variety and growth stage. By using a detachable spring 5-2, users can easily replace springs 5-2 with different elastic strengths according to the specific grafting object. This design ensures that the clamp 5 provides sufficient holding force during clamping, ensuring close contact between the scion and rootstock to promote callus formation, while effectively avoiding damage to the scion or rootstock due to over-clamping, thereby improving the grafting success rate and survival rate.

[0050] In addition, a rubber pad is added to the inner side of the clamping end of the gripper 5-1. The rubber pad is a material with good elasticity and flexibility, and its placement plays a crucial role in clamping the peony branches. On the one hand, the rubber pad increases the friction between the gripper 5-1 and the branch, making the clamping more secure and reducing the possibility of the branch slipping. On the other hand, the rubber pad can also effectively cushion the pressure of the gripper 5-1 on the branch, avoiding mechanical damage caused by hard contact, such as clamp marks or pressure sores, thereby better protecting the epidermis and internal tissues of the peony branch and promoting healthy growth and wound healing.

[0051] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
