[0002] Cowpea is a common leguminous plant, belonging to an annual twining herb. Its fruit is a long strip-shaped pod, usually green, and is one of the common vegetables on people's dinner tables. Cowpea is rich in nutrients such as protein, vitamins and minerals, and has high nutritional value and various cooking methods.

[0003] The cowpea anti-sheathing device is a tool used to assist the climbing growth of cowpeas and avoid the chaos of stem vines entanglement. Generally, it consists of a support structure, a sheathing tube and fixing components, etc. The sheathing tube provides a directional growth space for the cowpea stem vines, the support structure stabilizes the sheathing tube, and the fixing components fix the device in the field to guide the cowpeas to climb and grow orderly.

[0004] In the prior art, some cowpea anti-sheathing devices have many problems in the actual use of the existing cowpea protection sheathing tubes. Traditional sheathing tubes mostly adopt connection methods such as buckles and straps. The installation process is cumbersome, which requires a lot of manual time and energy. Especially in large-scale planting scenarios, the installation efficiency is low, seriously affecting the progress of farming operations. During the growth process of cowpeas, the stem vines will continuously elongate and thicken. The traditional sheathing tubes lack an adaptive adjustment structure and are difficult to change the size as the cowpeas grow, which is easy to bind the cowpea stem vines, hinder the normal growth of the plants, cause stem vine damage and breakage, reduce the survival rate and yield of cowpeas. Therefore, a cowpea anti-sheathing device is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a cowpea anti-sheathing device, aiming to improve the problems of stem vine damage and breakage in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A cowpea anti-sheathing device includes a first sheathing tube. A connection groove is formed inside the first sheathing tube. Two first springs are fixedly connected to the rear inner wall of the connection groove. A linkage ring is fixedly connected to the front sides of the two first springs. An engagement groove is formed inside the linkage ring. A second sheathing tube is rotatably connected to the right side of the first sheathing tube. A T-shaped ring is fixedly connected to the left side of the second sheathing tube. Two stop blocks are fixedly connected to the front side of the engagement groove. Two fixing components are formed inside the second sheathing tube for facilitating the fixation during cowpea grafting.

[0008] As a further description of the above technical solution:

[0009] The fixed component includes a driven groove, and a plurality of second springs are fixedly connected to the right inner wall of the driven groove. The left sides of the plurality of second springs are fixedly connected to a driven ring, and two adjusting knobs are threadedly connected to the right side of the second sleeve.

[0010] As a further description of the above technical solution:

[0011] The left side of the adjusting knob is fixedly connected to a third spring, and the left side of the driven ring is fixedly connected to a fixed ring.

[0012] As a further description of the above technical solution:

[0013] The outside of the linkage ring is slidably connected to the inside of the connection groove, and the outside of the T-shaped ring is in contact with the inner wall of the connection groove.

[0014] As a further description of the above technical solution:

[0015] The rear side of the T-shaped ring is in contact with the left sides of the two stoppers, and the outside of the fixed ring is slidably connected to the left side of the second sleeve.

[0016] As a further description of the above technical solution:

[0017] A first through hole is respectively formed in the inside of the first sleeve and the inside of the second sleeve, and a second through hole is formed in the inside of the linkage ring.

[0018] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] Two rubber pads are fixedly connected to the right side of the first sleeve, and the outside of the driven groove is formed in the inside of the second sleeve.

[0022] The utility model has the following beneficial effects:

[0023] 1. In the present utility model, by placing the first sleeve and the second sleeve outside the cowpea, and then rotating the second sleeve to make the T-shaped ring snap into the engagement groove of the linkage ring, the rapid connection and fixation of the first sleeve and the second sleeve are achieved. During the growth process of the cowpea, the thrust generated by the vine acts on the T-shaped ring, the T-shaped ring pushes the stopper, driving the linkage ring to slide in the connection groove, and simultaneously compressing the first spring. Thus, the fitting structure of the T-shaped ring and the engagement groove is used to replace the traditional complex assembly method, significantly improving the operation efficiency. Based on the adaptive telescopic design of the spring's elasticity, it can automatically respond to the thrust generated by the growth of the cowpea, eliminating the need for manual adjustment, and effectively reducing the growth hindrance of the vine caused by the restraint of the protective device.

[0024] 2. In the present utility model, the fixed ring can closely fit the surface of the cowpea through the elasticity of the second spring to complete the preliminary fixation. When it is necessary to adjust the fixing force according to the situation of the cowpea, the operator rotates the adjustment knob, driving the third spring to apply pressure to the driven ring, changing the compression amount of the second spring, and then precisely adjusting the fixing force of the fixed ring on the cowpea. Thus, it realizes the adaptive fitting to the surface of the cowpea, avoiding damage caused by rigid clamping, and can adjust the fixing force as needed to accurately meet the support requirements at different growth stages of the cowpea, simplifying the frequent manual adjustment operation, and effectively reducing the problems of plant shaking and breaking caused by improper fixation.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figures 1 to 3 , an embodiment provided by the present utility model: a cowpea anti-sheath device, including a first sleeve 1. The first sleeve 1 provides a mounting space support for the internal device. A connecting groove 2 is opened inside the first sleeve 1, and the connecting groove 2 provides fixation and support for a first spring 3. Two first springs 3 are fixedly connected to the rear inner wall of the connecting groove 2. The first springs 3 have an elastic effect. A linkage ring 4 is fixedly connected to the front side of the two first springs 3. The linkage ring 4 provides a space for opening an engagement groove 5. An engagement groove 5 is opened inside the linkage ring 4. The engagement groove 5 is used to place a T-shaped ring 7. The right side of the first sleeve 1 is rotatably connected to a second sleeve 6, and the second sleeve 6 provides fixation and support for the T-shaped ring 7;

[0033] A T-shaped ring 7 is fixedly connected to the left side of the second sleeve 6. The T-shaped ring 7 is used to be inserted into the inside of the engagement groove 5 for quick connection and fixation. When the cowpea grows, a force can be applied to the linkage ring 4 through the T-shaped ring 7. Two stoppers 8 are fixedly connected to the front side of the engagement groove 5. Then, a force is applied to the stoppers 8 through the T-shaped ring 7. Further, the stoppers 8 can drive the linkage ring 4 to slide synchronously. Further, the linkage ring 4 can adapt through the elastic effect of the first spring 3. Two fixing components are opened inside the second sleeve 6 for facilitating the fixation during cowpea grafting.

[0034] Referring to Figure 3 and Figure 4 , the fixing component includes a driven groove 9. The driven groove 9 provides fixation and support for a second spring 10. A plurality of second springs 10 are fixedly connected to the right inner wall of the driven groove 9. The second springs 10 have an elastic effect and provide elastic support for a driven ring 11. The left side of the plurality of second springs 10 is fixedly connected to a driven ring 11. The driven ring 11 is used to provide elastic support for a fixing ring 14. Two adjusting knobs 12 are threadedly connected to the right side of the second sleeve 6. An operator can apply a force to a third spring 13 by rotating the adjusting knob 12, and further adjust the fixing force of the driven ring 11.

[0035] Referring to Figures 2 to 4, on the left side of the adjusting knob 12, a third spring 13 is fixedly connected. The third spring 13 has an elastic effect and serves to connect the adjusting knob 12 and the driven ring 11. On the left side of the driven ring 11, a fixing ring 14 is fixedly connected. After the cowpea grafting is completed, the two fixing rings 14 are used to fix the grafting parts of the cowpea respectively. The outside of the linkage ring 4 is slidably connected inside the connecting groove 2, and the connecting groove 2 provides a limiting and guiding function for the linkage ring 4. The outside of the T-shaped ring 7 is in contact with the inner wall of the connecting groove 5. The T-shaped ring 7 is used to be inserted into the connecting groove 5, thereby completing the quick connection of the first sleeve 1 and the second sleeve 6;

[0036] The rear side of the T-shaped ring 7 is in contact with the left sides of the two stoppers 8. When the cowpea grows after the grafting is completed, a force can be exerted on the stopper 8 through the T-shaped ring 7, and then the stopper 8 drives the linkage ring 4 to slide, enabling it to adapt to the growth of the cowpea. The outside of the fixing ring 14 is slidably connected to the left side of the second sleeve 6. When the cowpea grows, through the elastic effect of the second spring 10, the fixing ring 14 can closely contact the surface of the cowpea to fix it. Through holes 16 are respectively provided inside the first sleeve 1 and the second sleeve 6. The through holes 16 can ventilate the surface of the cowpea at the grafting part;

[0037] A through hole 17 is provided inside the linkage ring 4. When the linkage ring 4 slides, the through hole 17 can correspond to the through hole 16 inside the first sleeve 1, thereby enabling ventilation of the surface of the cowpea. The left side of the third spring 13 is fixedly connected to the right side of the driven ring 11. The driven ring 11 can receive the force from the third spring 13 and then adjust the fixing force on the cowpea. The outside of the driven ring 11 is slidably connected inside the driven groove 9, and the driven groove 9 provides a limiting and guiding function for the driven ring 11. Two rubber pads 15 are fixedly connected to the right side of the first sleeve 1. The rubber pads 15 can cooperate with the fixing ring 14 to fix the surface of the cowpea. The outside of the driven groove 9 is provided inside the second sleeve 6, and the second sleeve 6 provides a space for the driven groove 9 to be opened.

[0038] Working principle: When in use, after the wet grafting of the cowpea is completed and protection is required for the grafting part of the cowpea, by placing the first sleeve 1 and the second sleeve 6 outside the cowpea, and then rotating the second sleeve 6 to make the T-shaped ring 7 snap into the connecting groove 5 of the linkage ring 4, the quick connection and fixation of the first sleeve 1 and the second sleeve 6 are achieved. During the growth of the cowpea, through the thrust generated by the vine acting on the T-shaped ring 7, the T-shaped ring 7 pushes the stopper 8, driving the linkage ring 4 to slide inside the connecting groove 2, and at the same time compressing the first spring 3. By utilizing the elasticity of the first spring 3, the device can adaptively expand and contract with the growth of the cowpea, ensuring that the device always fits closely to the cowpea.

[0039] When fixing the surface of the cowpea, place the grafted cowpea between the fixing ring 14 and the rubber pad 15. Through the elasticity of the second spring 10, the fixing ring 14 is closely attached to the surface of the cowpea to complete the preliminary fixation. When it is necessary to adjust the fixing force according to the situation of the cowpea, the operator rotates the adjustment knob 12 to drive the third spring 13 to apply pressure to the driven ring 11, changing the compression amount of the second spring 10, and then precisely adjusting the fixing force of the fixing ring 14 on the cowpea to ensure that the cowpea is stable and does not shake during growth, providing a reliable guarantee for the growth of the cowpea.
