’將因反作用力過大而導致使用者相當費力，尤其不能長 時間使用於修剪樹木的工作。 為此，參閱第一圖所示，習知的改良方式係將剪刀片 30的後端延伸有一介於兩握柄1〇、20之間的作動片3〇1，該 作動片301設有一條形孔302’並在條形孔302—側壁設有多 f個定位嵌槽303，另外在其中一握柄2〇樞設一連桿4〇，連 • 端透過-銷軸401穿置在條形孔3〇2中，藉此組成可 .刀奴剪切的園藝剪。當使用於修剪樹木時，可利用連桿 的鵠軸401在條形孔302變換嵌合於定位嵌槽303的位置，用 於分段剪斷樹枝。 然而習知可分段剪切的園藝剪，乃針對不易剪斷的粗 =枝所設計，然也因為上述的結構設計，必需按照施力、 細I、再施力這種反覆動作進行剪切，即使應用在修剪較 :的樹枝，也無法僅一次施力就剪斷較細樹枝，而必須依 遵知施力、放鬆、再施力這種反覆動作才能完成剪斷動 3 M420981 作，不免造成使用上的麻煩，有時反成省力而不省時的狀 況。再者，有些使用者未曾用過或尚未習慣上述可分段剪 切動作的園藝剪，當他們沒辦法一次施力就剪斷時或未遵 照多段剪切之動作而卡住時，往往以為園藝剪故障而摸不 著頭緒，胡亂地扭轉搖晃園藝剪，其時已經剪入樹枝的刀 片部分或柩鈕部位就容易被扭壞。 由上述可見，最佳的園藝剪應該要實施成可切換剪切 模式的結構，讓使用者面對不同粗細樹枝時，能選擇一次 施力剪斷的模式，反之當遇到要剪粗樹枝時，也能選擇分 次施力分段剪切的省力模式，才能最符合一般使用者園藝 工作上的彈性需求。 【新型内容】 本創作之主要目的在提供一種可切換剪切模式之園藝 剪，藉由第一握柄、第二握柄、刀片單元、驅動連桿及切 換元件的組合結構，特別是切換元件直線活動設置在第二 握柄的結構設計，進而達到可變換剪切模式、操作方便及

New description: [New technical field] This creation is related to a kind of gardening, especially a kind of garden shear structure improvement that can provide users to change the cutting mode. [Prior Art] As shown in the first figure, the conventional gardening shears are mainly applied to the trimming tree 'branches' by the shapes of the two grips 10, 20 and a special scissor blade 30, so that the garden shears are particularly suitable for shearing. Cut trees. However, simply using the force applied by the user to the grip-handles 10, 20 to drive the scissor blade 30, if a tree having a relatively large diameter is encountered, the user will be quite laborious due to excessive reaction force, especially for long-time use of trimming trees. work. To this end, referring to the first figure, the conventional modification is to extend the rear end of the scissor blade 30 with an actuating piece 3〇1 between the two grips 1 and 20, and the actuating piece 301 is provided with a strip. The hole 302' is provided with a plurality of f positioning slots 303 in the side wall of the strip hole 302, and a connecting rod 4 is pivoted on one of the handles 2, and the connecting end is inserted through the pin 401. In the shape of the hole 3 〇 2, thereby forming a gardening shear that can be cut by the knife. When used for trimming trees, the shank 401 of the connecting rod can be used to change the position of the mortise groove 303 in the strip hole 302 to cut the branch. However, the horticultural shears that can be cut in sections are designed for the rough-cut branches that are not easily cut. However, because of the above-mentioned structural design, it is necessary to cut according to the repeated action of applying force, fine I, and re-applying force. Even if it is applied to trimming the branches, it is impossible to cut the thin branches with only one force, and it is necessary to follow the force, relax, and apply the force to complete the shearing action. Causes trouble in use, sometimes it becomes a labor-saving and time-saving situation. Furthermore, some users have never used or are not accustomed to the above-mentioned gardening shears that can be segmented and sheared. When they can't cut it with one force or do not follow the multi-segment cutting action, they often think that gardening is If you cut the fault and you can't figure it out, it will twist the gardening shears indiscriminately, and the blade part or the button part that has been cut into the branches will be easily twisted. It can be seen from the above that the best gardening shears should be implemented in a switchable shear mode, allowing the user to select a mode of shearing when facing different thick and thin branches, and vice versa when encountering thick branches. It is also possible to select the labor-saving mode of splitting force and segmentation shearing in order to best meet the elastic needs of general users in gardening work. [New content] The main purpose of this creation is to provide a garden shear with switchable shear mode, by a combination of a first grip, a second grip, a blade unit, a drive link and a switching element, in particular a switching element The linear motion is set in the structural design of the second grip, thereby achieving the functions of transformable shear mode, convenient operation and easy manufacture. The second objective of this creation is to provide a gardening shear that can switch the cutting mode, and to design the combination of the safety fastener and the switching element, thereby achieving the purpose of safe collection and ingenious configuration. In order to achieve the above objective, the implementation of the gardening shear that can switch the cutting mode comprises: a first handle, the first front end of the first handle is provided with a first pivoting portion and a second pivoting portion, And a curved curved drill bit is arranged at the front end of the first grip; a second grip, the front end of the second grip is movable M420981 ". and the positioning position of the positioning groove of the actuating piece is changed. , allowing the user to apply force to the first and second grips in turn to achieve the segmentation mode to cut thick branches and labor-saving effects. Furthermore, 'this creation is better able to set the two components on the second handle through the structural design of the safety fastener and the structure in which the safety fastener and the switching element are combined with each other, and can utilize the safety fastener when the gardening shear is not used. The actuating piece of the blade unit is fastened, and the cut of the gardening shear is closed, thereby achieving the functions of safe collection and ingenious structure configuration. [Embodiment] The structural features and other functions and purposes of the present invention are described in detail below according to the embodiments of the drawings. Referring to the second and third figures, the creation can switch the shearing mode of the gardening shears. The gardening shear for changing the cutting mode for trimming the branches can be switched. The preferred embodiment comprises a first handle 1, a second handle 2, a blade unit 3, a drive link 4 and a switching element. 5, wherein the first handle 1 is formed by a plastic molding or a combination of a φ-shaped grip, and a first splicing portion n and a second portion are disposed at a front end of the first grip 1 The pivoting portion 12 is provided with a curved curved shape at the front end of the first grip i. The boring drill 13 can be formed or combined in the front end of the first grip shank 1 for The blade unit 3 cooperates to generate a shearing force. The second handle 2 is also integrally formed by plastic or assembled to form a rod-shaped handle, and the front end of the second handle 2 is pivotally recorded in the second pivoting portion 12 of the first handle ,. The second grip 2 is adjacent to the first gripper and can provide: the user grips the first grip i and the second grip 2 to apply a force. The blade unit 3 is a blade formed by stamping and grinding a metal sheet, and includes a scissors In 7 M420981 and an actuating piece 32 extending from the rear end of the scissor blade 31, and pivoting the blade unit 3 to the first grip 1 The first pivoting portion 11 is such that the knife edge 3U of the scissor blade corresponds to the blade cobalt sheet 13 of the first grip 1, and the actuating sheet 32 extends between the first grip 1 and the second grip 2, and The actuating piece 32 is provided with a through-shaped through hole 33. One side of the through hole 33 is provided with two or more semicircular positioning grooves 331 (four positioning grooves 331 as shown). The driving link 4 is a rod-shaped member that drives the blade unit 3 to be actuated. One end of the driving rod 4 is pivotally connected to the selected position of the handle of the second grip 2, and the other end of the opposite end is inserted through the bolt 51 to the blade unit 3. Among the through holes 33, the latch 41 can be displaced and inserted into the positioning groove 331, whereby the actuating piece 32 is pushed to actuate the scissors piece 31 at the front end for providing the user to cut the branches. The switching element 5 includes a force applying button 51 and a branch block 52 integrally formed or assembled to the force applying button 51, and the switching element 5 is disposed on the second handle 2 in a linear movable structure to support The block 52 can be linearly advanced against the edge of the actuating piece 32 of the blade unit 3, and can also be reversely receded away from the edge of the actuating piece 32 of the blade unit 3. By the combination of the first handle 1, the second handle 2, the blade unit 3, and the drive link 4, in particular, the switching element 5 is linearly arranged on the second handle 2, and the composition can be switched. The gardening shear of the cut mode can use the action of the switching element 5 to advance forward or backward to provide the user to select a knife cut (one force application) or a segment cut (split force) branch. Referring to the second figure, the switching element 5 of the present invention can be disposed on the second handle 2 and adjacent to the inner surface of the first handle 1 such that the support block 52 faces the actuating piece 32 of the blade unit 3, and The force button 51 faces the first handle. Or as shown in FIG. 11 , the switching element 5 can also be disposed on the second grip M420981 . . . 2 and adjacent to the inner surface of the first grip 1 such that the support block 52 faces the actuating piece 32 of the blade unit 3 . And the force button 51 protrudes from one side or both sides of the second handle 2, so that the user can more easily apply the force button 51. Wherein, the inner surface of the first handle 1 adjacent to the second handle 2 can be provided with a recess 21, whereby the switching element 5 is disposed in the groove 21 in a linear movable structure, and the supporting block of the changing element 5 is provided. 52 is directed toward the actuator 32 of the blade unit 3 for providing the user to advance forward or to withdraw. The linear movable structure may be a structure in which the sliding and the chute are matched (for example, as shown in the eighth figure) or other forms, and • a positioning function design may be implemented to cause the switching element 5 to advance forward or to exit to a fixed point. Referring to the second figure, the front end of the first grip 1 is provided with a through-cut seam U, whereby the blade unit 3 is placed in the slit 14 and is pivoted in the first grip. The first pivoting portion 11 of the handle 1. The first frame portion 11 includes a shaft hole ill perpendicularly extending through the slit 14 and a first pivot 112 disposed in the hole, and the first shaft 112 is disposed on the blade The single cymbal 3' in turn causes the blade unit 3 to be pivoted to the first gripper. When the user provides a user to use the garden to trim the branches, referring to the fourth and sixth figures, the switching element 5 can be advanced to cause the support block to move to the end position of the corresponding blade single το3 actuation piece 32. Switching the gardening shears into a mode in which the force can be cut. Therefore, referring to FIG. 4A, when the user holds the first grip and the second grip 2, the scissors piece 31 of the blade unit 3 is cut into the branch 1 同时 while the first grip The first pivoting portion 11 of the blade 3 drives the actuating piece 32 of the blade unit 3 toward the second gripping member 2 until the edge of the actuating piece 32 of the blade unit 3 abuts against the supporting block 52 of the switching member 20981. At the same time, as shown in FIG. 4B, when the user continues to apply force, the reaction force of the supporting block 52 against the actuating piece 32 will be utilized, and the actuating piece 32 will be prevented from abutting against the second grip 2, and the drive unit will be driven by itself. The latch 41 of the lever 4 continues to be moved forward and is inserted into the front positioning groove 331, so that the scissor blade 31 at the front end of the blade unit 3 can use this action to completely cut the branch 10 once. It can be seen that the design of the switching element 5 allows the user to cut the branches by applying a force, which is particularly suitable for trimming thin branches. Furthermore, the linearly movable structure is realized by the switching element 5, and the operation mode of the straight forward and backward pushing is simpler than the conventional gardening shear, and the support block 52 can reliably support the movable piece 32 at the rear end of the blade unit 3, A force-cut function. When the right side of the branch is to be thicker, the creation can also provide the user with a relatively labor-saving operation mode, and the branches are cut in sections by force. Referring to FIG. 5A, the user only needs to move the switching member 5 backwards to the end position of the blade unit 3 to move the blade 32, and then perform the work of trimming the branches. 'When the blade 31 of the blade unit 3 abuts against the branch 10 The latch 41 of the drive link 4 is embedded in the rear positioning slot 33ι of the through hole training. Referring to Fig. 5B, when the user applies a force, the driving link 32 can be used to cause the front end scissors U to cut the human branch 10 to a certain depth. Then, as shown in the fifth C picture, 'When the squatter can no longer apply force to the first handle!, 2, as long as the first and second grips are slightly loosened, the drive link 4 is driven by the second grip 2 The insertion direction is shifted forward and embedded in the front positioning groove 331. Referring to the fifth d-figure, finally applying the first and second grips 丄, 2, and then driving the M420981 through the drive link 4, the actuating piece 32 causes the leading blade 31 to completely cut the branch 10. It can be seen that if the branches are so thick that they cannot be sheared at one time, the branches can be cut by the above-mentioned splitting and force-cutting mode to achieve labor-saving effect. When the gardening shear of the present creation is not used, in order to prevent the knife edge 311 from opening and causing danger and preventing the knife σ311 from being damaged, referring to the sixth, seventh and eighth drawings, the preferred embodiment further includes a safety buckle. Item 6, the safety fastener 6 is movably disposed on the second grip 2 for the scissor blade 31 and the blade piece == the actuating piece 32 of the blade unit 3. Wherein, the safety fastener 6 is attached to the pivoting block 62 of the actuating piece 32, and the pivoting (10) is dragged to the handle. In the outer side of the recess 2 or in the recess 21, the safety fastener 6 can be used by the user to engage the actuating piece 32 of the blade unit 70 3 . The preferred fastening position of the safety fastener 6 may be the rear end of the actuating piece 32. Therefore, the rear end of the actuating piece 32 is provided with a tab 34 that is buckled by the buckle groove 63. No, when the blade of the scissor blade 31 and the blade drill >} 13 is closed, the safety fastener 6 can be pushed forward before the call, so that the buckle groove 63 is pressed against the tab Μ to prevent the blade 31 and the knife drill The blade of the piece 13 is opened to achieve the function of safely collecting and protecting the knife edge. Conversely, when the user needs to use the garden shears, just push back. The safety fasteners 6 will be able to open the garden shears. Referring to the sixth, eighth and ninth figures, since the first grip 2 of the present creation must be provided with a linearly movable switching element $, the branch block 52 of the switching element 5 can be passed through the safety fastener 6 The actuating piece 32' of the blade slanting direction of the blade unit 3 is designed such that not only the switching element 5 and the safety fastener 6 can be skillfully arranged on the second handle 2, but also the original function. In addition, the gardening shears of this creation are not limited to the short-handed hoe shears, as shown in the tenth figure. The size of each component can also be enlarged, and the first-grip! And the second grip 2 is lengthened, so that the large gardening shears constituting the long handle can also achieve the same effect by the configuration of the blade unit 3 and the switching member 5. ~ In summary, this creation can switch the shearing mode of gardening shears, which has been practical and practical. The use of its technical means is also out of new possibilities, and the effectiveness and design purpose of Chengcai really saves time. The purpose of saving effort is to say that it is reasonable to step to Ming.
