[0002] Tea refers to the leaves and buds of tea trees. Aliases include tea, jia, ming, and chuan. It generally refers to the leaves of evergreen shrub tea trees that can be used for making tea, as well as the beverages brewed from these leaves. Later, it was extended to all herbal teas brewed from plant flowers, leaves, seeds, and roots, such as "chrysanthemum tea", etc.; "cool teas" brewed from various medicinal materials, etc. In Chinese literature, it is also called Lei Ya. Tea is usually planted in tea fields, and when the tea trees mature, the tea trees are picked.
[0003] Currently, the method of picking tea is usually to pick tea manually or cut the tea with picking tools such as scissors. When using tools to pick tea, due to the long-term friction between the tool and the branches and leaves of the tea, after a long time of use, the tool blade is worn and needs to be replaced. Most of the existing equipment blades are installed on the picking tool as a whole. When one part of the blade is worn, the entire blade needs to be replaced together, which increases the material consumption and usage cost. Therefore, a tea picking auxiliary tool with a portable folding function is proposed to solve the above problems. Content of the Utility Model

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 , Figure 2 , Figure 4This utility model provides an embodiment of a portable folding tea picking aid, including a handle 1 and a support rod 2. A connecting block 18 is hinged to the right side of the support rod 2, and the end of the connecting block 18 away from the support rod 2 is hinged to the left side of the handle 1, so that the handle 1 and the support rod 2 can be folded to reduce the space occupied during storage. A housing 3 is fixedly connected to the left side of the support rod 2. The housing 3 is provided with two sets of movable arms 4. The housing 3 is provided with a drive device and a transmission structure, which can realize the effect of the two sets of movable arms 4 moving closer or further apart. This can be achieved by commonly used technical means in the field, such as using a combination of stepper motor, bidirectional screw and nut block. A mounting plate 5 is fixedly connected to the side of the two sets of movable arms 4 that are close to each other, and a mounting mechanism is provided on the outside of the mounting plate 5.
[0033] Reference Figure 4 - Figure 6 The mounting mechanism includes blade 6 and blade 7, which together form a complete tea picking and cutting knife. This modular design ensures efficient picking while precisely cutting the tea leaves, minimizing damage and maximizing the integrity and freshness of the leaves, thus improving tea quality. Both blades 6 and 7 have mounting grooves 8 on the side closest to the mounting plate 5, with the inner wall of the grooves contacting the outer wall of the mounting plate 5. Positioning blocks 9 are fixedly connected to the sides of blades 6 and 7 that are close to each other. On the sides that are close to each other, there are positioning grooves 10 that cooperate with the positioning block 9. The cooperation between the positioning block 9 and the positioning groove 10 improves the installation accuracy of blade 6 and blade 7 and enhances the stability of the connection between blade 6 and blade 7, ensuring that the cutting blade will not loosen during harvesting. Blade 6 and blade 7 are fixedly connected by fastening bolts 11. The surface of the mounting plate 5 has through holes 12, and the fastening bolts 11 pass through the inside of the through holes 12. If the cutting blade is worn or damaged, the fastening bolts 11 can be loosened to facilitate the disassembly and replacement of blade 6 and blade 7. The support rod 2 is equipped with a control mechanism inside.
[0034] Reference Figure 1 - Figure 3The control mechanism includes a sleeve 13, which is fitted onto the outer wall of the handle 1. There is always a contact between the inside of the sleeve 13 and the outer wall of the handle 1. When the sleeve 13 also contacts the support rod 2, the handle 1 and the support rod 2 are connected as a whole, so that the handle 1 and the support rod 2 cannot freely change their angle, thus forming a longer handle to facilitate tea picking. The inner diameter of the sleeve 13, the outer diameter of the handle 1, and the outer diameter of the support rod 2 are all equal. The control mechanism also includes a limiting cylinder 14 and a slider 15. The limiting cylinder 14 is fixedly connected to the circumferential surface of the slider 15. The outer wall of the limiting cylinder 14 fits against the inner wall of the sleeve 13, and the outer wall of the slider 15 fits against the inner wall of the handle 1.
[0035] Reference Figure 2 , Figure 3 A spring 16 is fixedly connected to the right side of the slider 15. The spring 16 is initially set to a stretched state. The right side of the spring 16 is fixedly connected to the inner wall of the handle 1. The slider 15 is elastically connected to the inner wall of the handle 1 through the spring 16. The spring 16 applies a spring force to the slider 15 to the right. A groove 17 is provided on the surface of the handle 1. The groove 17 is set to a J shape. The outer wall of the limiting cylinder 14 fits against the inner wall of the groove 17.
[0036] Working principle: During use, the stepper motor inside the housing 3 drives the bidirectional screw to rotate. The nut block that is threaded with the bidirectional screw is connected to the two sets of moving arms 4 respectively. As the bidirectional screw rotates, the nut block drives the two sets of moving arms 4 to move closer or further apart. When the moving arms 4 move closer together, they drive the blades on the inner side of the two sets of moving arms 4 to cut the tea leaves from the tea tree. At the same time, the rotation angle of the stepper motor output shaft can be precisely controlled, thereby realizing precise control of the movement displacement distance of the tea picking and cutting blade.
[0037] When the blade is damaged and needs to be replaced, the first blade 6 and the second blade 7 can be removed from the surface of the mounting plate 5 by loosening the fastening bolt 11. Then, the intact first blade 6 and the second blade 7 are brought close together, and the positioning block 9 is inserted into the positioning groove 10 for positioning, thus completing the assembly. Then, the mounting groove 8 formed by the assembly of the first blade 6 and the second blade 7 is inserted into the surface of the mounting plate 5, so that the inner wall of the mounting groove 8 is in contact with the outer wall of the mounting plate 5. Then, the fastening bolt 11 is passed through the through hole 12 and tightened, thereby fixing the first blade 6 and the second blade 7 on the mounting plate 5, thus completing the replacement and disassembly of the blade. When the blade is damaged, the damaged blade can be replaced individually.
[0038] When the item is finished and needs to be stored, push the limiting cylinder 14 to the left, causing it to move inside the J-shaped groove 17. The slider 15 moves to the left under the action of the limiting cylinder 14, overcoming the elastic force of the spring 16, and stretches the spring 16. The sleeve 13 moves to the left along with the limiting cylinder 14. When the limiting cylinder 14 moves to the leftmost side of the groove 17, the path of the groove 17 begins to turn to the right. At this time, release the limiting cylinder 14. Under the action of the spring 16, the sleeve 13, the limiting cylinder 14, and the slider 15 all begin to move to the right, so that the sleeve 13 completely disengages from the surface of the support rod 2. At this time, the angle between the handle 1 and the support rod 2 can be freely rotated, thereby realizing the folding and storage of the handle 1 and the support rod 2.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
