Description

Technical Field

[0001] The utility model relates to the technical field of tea and vegetable picking, in particular to a vegetable-selecting finger knife. Background Art

[0002] At present, for the manual picking of tea leaves and vegetable leaves, it mainly relies on the mutual twisting and pinching of the thumb and index finger to cut off. The pinching action is mainly completed by the mutual extrusion of the nail of the thumb and the side of the index finger. However, the sharpness of the nail is limited, and it often takes multiple efforts to cut off. Moreover, after high-frequency operation in this way, the nail and the side of the index finger are prone to soreness.

[0003] For example, the Chinese utility model patent (CN221355034U) discloses a rapid tea picking device, which records: "Comprising a main body, an inner cavity for fingers to pass through is arranged inside the main body, a base belt is arranged on the outer side wall of the main body, a knife body is arranged on the base belt, the inner side end of the knife body is fixedly connected to the base belt, and the outer side end of the knife body has a blade edge extending to the outside of the base belt, and the blade edge constitutes a cutting structure for cutting the tea stem when twisting the tea."

[0004] However, the above device does not protect the thumb during use. In the picking process, the area where the index finger wraps the main body is used as the supporting part, and the inner side of the thumb is used as the pressing part, resulting in the contact between the thumb and the knife body when squeezing the tea stem, which has certain safety hazards. Moreover, the knife body is only fixed by the friction force with the base belt, and its fixing effect is limited and there is a risk of falling. Therefore, this application proposes a vegetable-selecting finger knife. Summary of the Utility Model
