M273197 IV. Creation Instructions (3) " ------- ^ 一 (46) Pulling force, 'Pull to the branch to be cut, and clamp the branch, so when the branch is completely cut, the system The jaw (45) is clamped to the cutting board (43), and the cut branch is clamped. The conventional structure as described above uses the following missing ones: (1) If the fruit branch of the branch or fruit is pinched off, it only depends on the pulling force of the blade (44) to drive the yellow (46) to pull the jaw ( 45) It is clamped to the cutting board (43). The clamping force of this method is limited and cannot be applied to the cutting of heavier and thicker branches and fruits. When the cut object is slightly heavier, the object will still fall directly_ On the ground, it cannot achieve the purpose of slowly lowering after safe cutting, and the gravity is even greater at the moment when the object is cut. Even lighter objects often fall when using the cut; (2) Because the clamping force of the jaw (45) is simply determined by the turning tension i of the spring (46) driven by the blade (44), so if the pruning object is thick, the jaw (45) does not have enough tension space to Object holding is only suitable for trimming thinner objects. Therefore, in view of the lack of the conventional long-arm gardening shear structure, how to develop a new structure with more ideal practicability is really a breakthrough for the industry.新型 【New content】 The technical problems to be solved: Know the long-arm gardening shears structure, which breaks the fruit pedicles of branches or fruits. There is limited clamping force in this method, which cannot be applied to the cutting of the heavier and thicker two branches and fruits.
