Abstract
Description
Technical Field
[0001] This utility model relates to the field of gardening tools technology, and in particular to a cutting mechanism and gardening shears. Background Technology
[0002] Existing garden shears typically consist of a cutting mechanism and two handles. The cutting mechanism comprises two rotating cutting elements, with the two handles connected to each element for the user to hold. The user operates the handles to rotate the two cutting elements relative to each other, thus performing pruning. However, this structure has some problems in practical use. Due to varying user skill levels, the cutting mechanism is prone to over-opening or over-closing during use. This abnormal opening and closing not only requires additional force to complete the cutting action, reducing operational efficiency, but also easily damages plant branches, affecting the pruning effect. Furthermore, abnormal opening and closing increases friction between the cutting elements, accelerating tool wear and shortening the lifespan of the garden shears. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a shearing mechanism that, by setting a four-bar linkage structure and using a first limiting member to restrict the movement of the linkage, can effectively limit the opening and closing range of the first and second shear bodies, which helps to avoid excessive opening or closing and is convenient to use.
[0004] This utility model also proposes a gardening shears having the cutting mechanism.
[0005] According to a first aspect embodiment of the present invention, the shearing mechanism includes a first shear body, a second shear body, a first connecting rod, a second connecting rod, and a first limiting member. A first pivot shaft is provided between the first shear body and the second shear body, and they are pivotally connected via the first pivot shaft. Both the first connecting rod and the second connecting rod have a pivot end and a handle end for connecting a handle. A second pivot shaft is provided between the pivot ends of the first and second connecting rods, and they are pivotally connected via the second pivot shaft. The middle portion of the first connecting rod is pivotally connected to the first shear body, and the middle portion of the second connecting rod is pivotally connected to the second shear body, forming a four-bar linkage structure. The first limiting member is connected to the first pivot shaft and has a first limiting groove. The second pivot shaft is partially located in the first limiting groove. When the first and second connecting rods rotate relative to each other, they can drive the first and second shear bodies to rotate relative to each other and open / close. The second pivot shaft can move along the first limiting groove.
[0006] According to the embodiments of the present invention, the shearing mechanism has at least the following beneficial effects: In use, the handle ends of the first link and the second link are both connected to handles, so that the user can hold the handles to drive the first link and the second link to rotate relative to each other. Through the four-bar linkage structure, when the first link and the second link rotate relative to each other, the first shear body and the second shear body rotate relative to each other to open and close, thereby performing pruning operations on horticultural plants. By using the first link and the second link to add a force-saving lever effect, the first shear body and the second shear body can obtain a larger shearing force under the same force applied by the operating handle, thereby achieving force saving. By setting a first limiting member, which is connected to a first pivot shaft and the second pivot shaft is partially located in the first limiting groove of the first limiting member, when the first shear body and the second shear body rotate relative to each other to open and close, the second pivot shaft moves along the first limiting groove. The first limiting groove restricts the displacement of the second pivot shaft relative to the first pivot shaft, thereby limiting the movement of the four-bar linkage. This effectively limits the opening and closing range of the first and second shear bodies, helps to avoid excessive opening or closing, reduces operational inconvenience and the risk of accidentally damaging plants due to abnormal opening and closing, and also reduces tool wear and tear, making it easier to use.
[0007] According to some embodiments of the present invention, the shearing mechanism further includes a buffer block, which is disposed on the side of the first limiting member away from the first pivot shaft. When the first shear body and the second shear body rotate relative to each other and close, the first shear body and the second shear body and / or the first connecting rod and the second connecting rod can move to contact the buffer block.
[0008] According to some embodiments of the present invention, the shearing mechanism further includes a second limiting member. The first limiting member and the second limiting member are respectively disposed at both ends of the first pivot shaft. The second limiting member is provided with a second limiting groove. Both ends of the second pivot shaft are respectively located in the first limiting groove and the second limiting groove. The buffer block is sandwiched between the first limiting member and the second limiting member.
[0009] According to some embodiments of the present invention, both the first pivot shaft and the second pivot shaft are bolts, and both the first limiting member and the second limiting member are provided with connecting holes corresponding to the end of the first pivot shaft.
[0010] According to some embodiments of the present invention, a connecting member is provided between the first limiting member and the second limiting member, and the connecting member passes through the buffer block and connects and fixes the first limiting member and the second limiting member.
[0011] According to some embodiments of the present invention, one of the buffer block and the first limiting member is provided with a limiting part, and the other is provided with a limiting hole for the limiting part to be inserted.
[0012] According to some embodiments of the present invention, one of the buffer block and the second limiting member is provided with a limiting part, and the other is provided with a limiting hole for the limiting part to be inserted.
[0013] According to some embodiments of the present invention, one of the first shear body and the second shear body is provided with a notch for accommodating plant branches, and the other is provided with a corresponding convex blade that can cooperate with the notch.
[0014] According to some embodiments of the present invention, both the first scissor and the second scissor are provided with a blade portion extending in a preset direction.
[0015] Gardening shears according to a second aspect of the present invention include a cutting mechanism according to the first aspect of the present invention described above.
[0016] The gardening shears according to the embodiments of this utility model have at least the following beneficial effects: by adopting the above-mentioned shearing mechanism, the four-bar linkage structure can be used to add a force-saving lever action. Under the same force applied to the operating handle, the first and second shearing bodies can obtain a larger shearing force, thereby saving effort. Furthermore, the first limiting member can be used to restrict the movement of the four-bar linkage structure, which can better limit the opening and closing range of the first and second shearing bodies, which helps to avoid excessive opening or closing, reduces the inconvenience of operation and the risk of accidentally damaging plants caused by abnormal opening and closing, and at the same time reduces the wear and tear of the tool and makes it easy to use.

[0035] Reference Figure 2 , Figure 3 and Figure 5 A shearing mechanism includes a first shear body 110, a second shear body 120, a first connecting rod 210, a second connecting rod 220, and a first limiting member 310. A first pivot shaft 130 is provided between the first shear body 110 and the second shear body 120, and the two shear bodies are pivotally connected via the first pivot shaft 130. Both the first connecting rod 210 and the second connecting rod 220 have a pivot end and a handle end for connecting a handle 400. A second pivot shaft 230 is provided between the pivot end of the first connecting rod 210 and the pivot end of the second connecting rod 220, and the two shear bodies are pivotally connected via the second pivot shaft 230. The first connecting rod 210 is pivotally connected to the first shear body 110 at its middle part, and the second connecting rod 220 is pivotally connected to the second shear body 120 at its middle part, forming a four-bar linkage structure. The first limiting member 310 is connected to the first pivot shaft 130 and is provided with a first limiting groove 301. The second pivot shaft 230 is partially located in the first limiting groove 301. When the first connecting rod 210 and the second connecting rod 220 rotate relative to each other, they can drive the first shear body 110 and the second shear body 120 to rotate relative to each other and open and close. The second pivot shaft 230 can move along the first limiting groove 301.
[0036] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the middle part of the first shear body 110 and the middle part of the second shear body 120 are pivotally connected by the first pivot shaft 130, forming a scissor shape. The upper ends of the first connecting rod 210 and the upper ends of the second connecting rod 220 are both pivot ends and are pivotally connected by the second pivot shaft 230. The lower ends of the first connecting rod 210 and the lower ends of the second connecting rod 220 are both handle ends for connecting the handle 400. A third pivot shaft 241 is provided between the lower end of the first shear body 110 and the middle part of the first connecting rod 210 and is pivotally connected by the third pivot shaft 241. A fourth pivot shaft 242 is provided between the lower end of the second shear body 120 and the middle part of the second connecting rod 220 and is pivotally connected by the fourth pivot shaft 242 to form a four-bar linkage structure. The first limiting member 310 is connected to the first pivot shaft 130 and is provided with a first limiting groove 301 extending in the vertical direction. The second pivot shaft 230 is partially located in the first limiting groove 301.
[0037] Reference Figure 1 In use, the handle ends of the first link 210 and the second link 220 are both connected to handles 400, allowing the user to grip the handles 400 and drive the first link 210 and the second link 220 to rotate relative to each other. (Refer to...) Figure 2 and Figure 5 The four-bar linkage structure allows the first link 210 and the second link 220 to rotate relative to each other, which in turn drives the first shear body 110 and the second shear body 120 to rotate relative to each other and open and close, thereby performing pruning operations on horticultural plants. By utilizing the first link 210 and the second link 220 to add a force-saving lever effect, the first shear body 110 and the second shear body 120 can obtain a larger shearing force when the same amount of force is applied by the operating handle 400, thereby achieving force saving. By setting a first limiting member 310, which is connected to the first pivot shaft 130 and the second pivot shaft 230 is partially located in the first limiting groove 301 of the first limiting member 310, when the first shear body 110 and the second shear body 120 rotate relative to each other to open and close, the second pivot shaft 230 moves along the first limiting groove 301. The distance between the first pivot shaft 130 and the third pivot shaft 241 is fixed, and similarly, the distance between the first pivot shaft 130 and the fourth pivot shaft 242 is fixed, and the distance between the second pivot shaft 230 and the fourth pivot shaft 242 is also fixed. The distance between the first pivot shaft 130 and the second pivot shaft 230 changes with the relative rotation of the two connecting rods. The left and right sides of the shearing mechanism form triangles with varying lengths on one side. The first limiting groove 301 restricts the displacement of the second pivot shaft 230 relative to the first pivot shaft 130, thereby limiting the range of change of the triangle and thus restricting the movement of the four-bar linkage. This effectively limits the opening and closing amplitude of the first shear body 110 and the second shear body 120, which helps to avoid excessive opening or closing, reduces the inconvenience of operation and the risk of accidentally damaging plants caused by abnormal opening and closing, and also reduces tool wear and tear, making it easier to use.
[0038] In practical applications, the specific structure of the first shear body 110, the second shear body 120, the first connecting rod 210, the second connecting rod 220 and the first limiting member 310 and the specific connection between them can be set according to the actual use needs. They will not be described in detail here, but will be explained in detail below.
[0039] In some embodiments, the shearing mechanism further includes a buffer block 320, which is disposed on the side of the first limiting member 310 away from the first pivot shaft 130. When the first shear body 110 and the second shear body 120 rotate relative to each other and close, the first shear body 110 and the second shear body 120 and / or the first connecting rod 210 and the second connecting rod 220 can move to contact the buffer block 320.
[0040] Understandably, such as Figure 2 and Figure 3 As shown, the upper side of the first limiting member 310 is connected to the first pivot shaft 130, and the lower side is provided with a buffer block 320. When the first shear body 110 and the second shear body 120 rotate relative to each other and close, the first shear body 110, the second shear body 120, the first connecting rod 210, and the second connecting rod 220 can all move to contact the buffer block 320, thereby using the buffer block 320 to buffer the closing situation and reduce the possibility of rigid collisions between the two shear bodies and the two connecting rods, making it convenient to use. In practical applications, in addition to the above method, the buffer block 320 can also be used to contact the first shear body 110 and the second shear body 120 during rotational closing, or to disengage from the first connecting rod 210 and the second connecting rod 220 to buffer the closing situation. The material of the buffer block 320 can be rubber or silicone, etc., and its specific structure can be changed according to actual use needs.
[0041] In some embodiments, the shearing mechanism further includes a second limiting member 330, with the first limiting member 310 and the second limiting member 330 respectively disposed at both ends of the first pivot shaft 130, the second limiting member 330 having a second limiting groove 302, the two ends of the second pivot shaft 230 being located in the first limiting groove 301 and the second limiting groove 302 respectively, and the buffer block 320 being sandwiched between the first limiting member 310 and the second limiting member 330.
[0042] Understandably, such as Figure 2 , Figure 3 and Figure 4 As shown, the first limiting member 310 and the second limiting member 330 are respectively disposed at the front and rear ends of the first pivot shaft 130. The second limiting member 330 is provided with a second limiting groove 302, which corresponds to the first limiting groove 301. The front and rear ends of the second pivot shaft 230 are respectively located in the first limiting groove 301 and the second limiting groove 302, thereby stably limiting the movement of the second pivot shaft 230. Furthermore, the first limiting member 310 and the second limiting member 330 can be used to clamp and fix the buffer block 320, facilitating the installation and fixation of the buffer block 320. In practical applications, the second limiting member 330 can be configured according to actual usage needs.
[0043] In some embodiments, the first pivot shaft 130 and the second pivot shaft 230 are both bolts, and the first limiting member 310 and the second limiting member 330 are both provided with connecting holes 303 corresponding to the end of the first pivot shaft 130.
[0044] Understandably, such as Figure 2 , Figure 3 and Figure 4As shown, the first pivot shaft 130, the second pivot shaft 230, the third pivot shaft 241, and the fourth pivot shaft 242 are all bolts. The shearing mechanism also includes multiple corresponding threaded nuts 140. Connecting holes 303 are provided on the upper side of the first limiting member 310 and the upper side of the second limiting member 330. The front end of the first pivot shaft 130 is located in the connecting hole 303 on the first limiting member 310, and its rear end passes through the connecting hole 303 on the second limiting member 330 and is threadedly engaged with the corresponding nut 140, thereby realizing the pivot connection between the first shear body 110 and the second shear body 120, as well as the connection with the first limiting member 310 and the second limiting member 330. Its structure is simple, the connection is stable and reliable, and it is easy to use. In practical applications, the first pivot shaft 130 and the second pivot shaft 230 can also be other structures, which can be set according to actual usage needs.
[0045] In some embodiments, a connecting member 340 is provided between the first limiting member 310 and the second limiting member 330. The connecting member 340 passes through the buffer block 320 and connects and fixes the first limiting member 310 and the second limiting member 330.
[0046] Understandably, such as Figure 2 , Figure 3 and Figure 4 As shown, the connector 340 is located below the first limiting member 310. The connector 340 is a riveted component, which sequentially passes through the first limiting member 310, the buffer block 320, and the second limiting member 330 in the front-to-back direction, and rivets the first limiting member 310, the buffer block 320, and the second limiting member 330 together. This allows the buffer block 320 to be well clamped and fixed between the first limiting member 310 and the second limiting member 330. Its structure is simple and facilitates the assembly and use of the buffer block 320. In practical applications, the connector 340 can also be a bolt or other threaded component. Of course, the first pivot shaft 130, the second pivot shaft 230, etc., can also be connected using a riveting structure. In addition to the above structures, the buffer block 320 can also be fixed between the first limiting member 310 and the second limiting member 330 by snap-fit or adhesive methods, which can be set according to actual usage needs.
[0047] In some embodiments, one of the buffer block 320 and the first limiting member 310 is provided with a limiting part 311, and the other is provided with a limiting hole 304 for the limiting part 311 to be inserted.
[0048] Understandably, such as Figure 3 and Figure 4As shown, a limiting hole 304 is provided on the buffer block 320, and correspondingly, a limiting part 311 is provided on the first limiting member 310. During assembly, the connecting member 340 passes through the first limiting member 310, the buffer block 320, and the second limiting member 330. The limiting part 311 is inserted into the limiting hole 304 to restrict the rotation of the buffer block 320 relative to the connecting member 340, thereby better fixing the installation position of the buffer block 320, preventing it from loosening or shifting, and facilitating its use. In practical applications, the limiting hole 304 can also be provided on the first limiting member 310, in which case the limiting part 311 is correspondingly provided on the buffer block 320. The specific setting can be adjusted according to actual usage needs.
[0049] In some embodiments, one of the buffer block 320 and the second limiting member 330 is provided with a limiting part 311, and the other is provided with a limiting hole 304 for the limiting part 311 to be inserted.
[0050] Understandably, in addition to the space between the buffer block 320 and the first limiting member 310, a limiting structure can also be provided between the buffer block 320 and the second limiting member 330. For example, a limiting hole 304 can be provided on the buffer block 320, and a limiting part 311 for inserting into the limiting hole 304 can be provided on the second limiting member 330. Alternatively, both the first limiting member 310 and the second limiting member 330 can be provided with limiting parts 311, and the buffer block 320 can be provided with a through limiting hole 304 or two limiting holes 304. Or, the first limiting member 310 and the second limiting member 330 can be provided with limiting parts 311 and limiting holes 304 respectively, and the buffer block 320 can be provided with limiting holes 304 and limiting parts 311 respectively. In practical applications, the arrangement of the limiting parts 311 and the limiting holes 304 can be changed according to actual usage needs.
[0051] In some embodiments, one of the first shear body 110 and the second shear body 120 is provided with a notch 101 for accommodating plant branches, and the other is provided with a corresponding protruding blade 121 that can cooperate with the notch 101.
[0052] Understandably, such as Figure 2 and Figure 5 As shown, the illustrated structure represents a first embodiment of the shearing mechanism. A notch 101 is located in the first shear body 110, and a protruding blade 121 is located in the second shear body 120. In use, plant branches can be placed in the notch 101. Rotating the handle 400 causes the first and second shear bodies 110 and 120 to rotate relative to each other and close. The protruding blade 121, in conjunction with the notch 101, cuts the plant branches, preventing slippage of the plant branches relative to the shear bodies and facilitating the trimming of harder or thicker plant branches. In practical applications, the notch 101 can also be located in the second shear body 120, with the protruding blade 121 correspondingly located in the first shear body 110. The specific configuration can be adjusted according to actual usage requirements.
[0053] In some embodiments, both the first shear body 110 and the second shear body 120 are provided with a blade portion 111 extending in a preset direction.
[0054] Understandably, such as Figure 6 As shown, the illustrated structure represents a second embodiment of the shearing mechanism. Both the first shear body 110 and the second shear body 120 are provided with blades 111 extending along a preset direction. In use, the first shear body 110 and the second shear body 120 rotate relative to each other and retract, allowing the blades 111 on both shear bodies to work together to cut the plant, making it convenient to use. In practical applications, a serrated structure 102 can also be provided on the blades 111 to increase its functionality; the specific design can be adjusted according to actual usage needs.
[0055] Gardening shears according to a second aspect embodiment of the present invention, such as Figure 1 As shown, it includes a handle 400 and a shearing mechanism according to the first aspect embodiment of the present invention. Two handles 400 are provided, and the two handles 400 are respectively connected to the handle 400 part of the first connecting rod 210 and the handle 400 part of the second connecting rod 220.
[0056] According to the garden shears of this utility model embodiment, by adopting the above-mentioned cutting mechanism, it can use the four-bar linkage structure to add a force-saving lever effect. Under the same force applied by the operating handle 400, the first shear body 110 and the second shear body 120 can obtain a larger shearing force, thereby saving effort. Furthermore, the first limiting member 310 can restrict the movement of the four-bar linkage structure, which can better limit the opening and closing range of the first shear body 110 and the second shear body 120, which helps to avoid excessive opening or closing, reduces the inconvenience of operation and the risk of accidentally damaging plants caused by abnormal opening and closing, and at the same time reduces tool wear and is easy to use.
[0057] In practical applications, the handle 400 and the cutting mechanism can be connected using a detachable or non-detachable structure. The handle 400 can be equipped with a telescopic structure to allow its length to vary and adapt to different usage needs. Since other components of the garden shears in this embodiment are known to those skilled in the art, they will not be described in detail here.
[0058] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
