Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea picking ruler technology, specifically, to a retractable finger-type tea picking ruler. Background Technology
[0002] Wuyi rock tea gets its name from the saying "tea grows on rocks, and there is no tea without rocks." It is a semi-fermented tea, a type of oolong tea, and is known for its unique "rocky charm" with "rocky essence and floral fragrance." The main production area is the Wuyi Mountain tea region in Fujian, China. Wuyi rock tea is mainly produced in the Wuyi Mountain area in northern Fujian Province. It is the finest of Chinese oolong teas and one of China's top ten famous teas. Wuyi rock tea has a long history and embodies great local characteristics.
[0003] Currently, the three methods of hand-picking Wuyi rock tea leaves—hand picking, blade picking, and scissor picking—all have various drawbacks. For example, hand-picking with fingers or picking with fingers tied to blades can easily lead to uneven cuts on the tea stems, resulting in inconsistent moisture loss during subsequent processing and affecting the quality of the tea leaves. Hand-picking with scissors can easily result in tea leaves of varying lengths, leading to inconsistent quality during subsequent withering, shaking, fermentation, pan-frying, and rolling. Furthermore, Wuyi rock tea varieties are diverse, and there is no unified standard for picking size. When picking by hand, a single tea picker cannot guarantee that each tea leaf is of consistent length based solely on feel, making standardization impossible. When multiple people are picking, it is even more difficult to unify standards, especially in contiguous tea gardens where multiple varieties are being harvested simultaneously. Because the picking length standards for different varieties are different, tea pickers are more likely to confuse the picking standards for different varieties.
[0004] To address the aforementioned issues, this application proposes a retractable finger-type tea-picking ruler. Utility Model Content
[0005] To address the problems in related technologies, this utility model provides a retractable finger-type tea picking ruler, which can ensure that each tea leaf and stem is of uniform length, and can also flexibly adjust the size according to different rock tea varieties to meet the picking needs of different varieties.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] A retractable finger-loop tea-picking ruler includes a main ruler, a mounting groove at the bottom of the main ruler, a first telescopic ruler slidably connected in the mounting groove, a sliding groove at the bottom of the first telescopic ruler, a second telescopic ruler slidably connected in the sliding groove, and two finger loops installed on the main ruler. The main ruler, the first telescopic ruler, and the second telescopic ruler are all marked with graduations.
[0008] As a further embodiment of this utility model, the main scale is set to a red color for easy identification, the first telescopic scale is set to a yellow color for easy identification, and the second telescopic scale is set to a blue color for easy identification.
[0009] As a further embodiment of this utility model, the main scale, the first telescopic scale, and the second telescopic scale are all made of soft plastic.
[0010] As a further embodiment of this utility model, the main scale is installed on the left thumb of the tea picker via a finger ring.
[0011] As a further embodiment of this utility model, the length of the main scale is set to 8cm, the scale markings on the first telescopic scale are 9cm and 10cm, and the scale markings on the second telescopic scale are 11cm and 12cm.
[0012] The beneficial effects of this utility model are as follows:
[0013] This utility model uses a main ruler, a first telescopic ruler, and a second telescopic ruler to work together. When used, tea pickers strictly follow the prescribed procedures to ensure that each tea leaf and stem is of uniform length, thus achieving consistent tea leaf picking standards. In addition, the first and second telescopic rulers can be adjusted to different lengths according to the picking requirements of different rock tea varieties, thereby meeting the requirements for distinguishing different stem lengths and effectively addressing the picking needs of different varieties.

[0023] According to an embodiment of the present invention, a retractable finger-type tea-picking ruler is provided.
[0024] Please refer to the instruction manual appendix. Figure 1-5 According to an embodiment of the present invention, a retractable finger-loop tea-picking ruler includes a main ruler 1, a mounting groove 2 at the bottom of the main ruler 1, a first telescopic ruler 3 slidably connected in the mounting groove 2, a sliding groove 4 at the bottom of the first telescopic ruler 3, a second telescopic ruler 5 slidably connected in the sliding groove 4, and two finger loops 6 installed on the main ruler 1. The main ruler 1, the first telescopic ruler 3, and the second telescopic ruler 5 are all marked with graduations. The length of the main ruler 1 is 8cm, the graduations on the first telescopic ruler 3 are 9cm and 10cm, and the graduations on the second telescopic ruler 5 are 11cm and 12cm. By using the main ruler 1, the first telescopic ruler 3, and the second telescopic ruler 5 in conjunction, tea pickers can ensure that each tea leaf and stem is of uniform length when used in strict accordance with regulations, thus achieving a consistent standard for tea leaf picking. In addition, the first telescopic ruler 3 and the second telescopic ruler 5 can be adjusted to different lengths according to the picking requirements of different rock tea varieties, thereby meeting the requirements for distinguishing different stem lengths and effectively addressing the picking needs of different varieties.
[0025] In one embodiment, please refer to the appendix to the specification. Figure 1As a further embodiment of this invention, the main scale 1 is set to a easily identifiable red color, the first telescopic scale 3 is set to an easily identifiable yellow color, and the second telescopic scale 5 is set to an easily identifiable blue color. By using different distinguishing colors, it facilitates the use by tea pickers.
[0026] In one embodiment, please refer to the appendix to the specification. Figure 3 As a further embodiment of this utility model, the main ruler 1, the first telescopic ruler 3, and the second telescopic ruler 5 are all made of soft plastic. The main ruler 1 is mounted on the tea picker's left thumb via a finger loop 6. The finger loop 6 facilitates fixing the main ruler 1 to the left thumb, and the soft plastic material of the ruler does not affect the comfort of tea picking operations.
[0027] Workflow: In use, first, the main ruler 1 is installed on the tea picker's left thumb using the finger ring 6. When picking short-stemmed tea varieties, the tea picker grasps the tea leaves with their left hand, aligning the bud at the top of the tea stem with the predetermined 8cm mark. With their right hand, they use scissors to cut the tea stem along the 0cm mark on the ruler, thus obtaining a standard 8cm tea leaf. When picking medium-stemmed tea varieties, the tea picker first extends the first telescopic ruler 3 from within the main ruler 1 to the predetermined length. Then, the tea picker grasps the tea leaves with their left hand and cuts the tea stem... Align the top bud with the predetermined 10cm mark, and use scissors in your right hand to cut the tea stem along the 0cm mark on the ruler to obtain a standard 10cm tea leaf. When picking long-stemmed tea varieties, the tea picker will extend the second telescopic ruler 5 from the first telescopic ruler 3 to the predetermined length. Then, the tea picker will hold the tea leaf with their left hand, align the top bud with the predetermined 12cm mark, and use scissors in their right hand to cut the tea stem along the 0cm mark on the ruler to obtain a standard 12cm tea leaf.
[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
