Lockable garden shears

Abstract

This invention discloses a lockable garden shears, comprising a first shear body, a second shear body, and a locking mechanism. The first shear body has a pivot fixedly connected to it, and the second shear body is pivotally connected to the pivot. The locking mechanism is located on the pivot and has a locked state and a working state. In the locked state, when the first and second shear bodies are cutting, the locking mechanism, along with the pivot and the second shear body, cooperates to restrict the relative rotation of the first and second shear bodies. In the working state, the first and second shear bodies can rotate relative to each other. When it is necessary to lock the shears, the locking mechanism is operated, causing it to engage with the second shear body and the pivot. Since the pivot is fixedly connected to the first shear body, the second shear body can be indirectly fixedly connected to the first shear body, preventing the first and second shear bodies from opening and reducing the risk of accidental injury to the user.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Reference Figures 1 to 3According to a first aspect of the present invention, a lockable garden shears includes a first shear body 100, a second shear body 200, and a locking mechanism 300. The first shear body 100 is provided with a pivot 110, which is fixedly connected to the first shear body 100. The second shear body 200 is pivotally connected to the pivot 110. The locking mechanism 300 is disposed on the pivot 110. The locking mechanism 300 has a locked state and a working state. In the locked state, when the first shear body 100 and the second shear body 200 are cutting together, the locking mechanism 300 can cooperate with the pivot 110 and the second shear body 200 to restrict the relative rotation of the first shear body 100 and the second shear body 200. In the working state, the locking mechanism 300 can not cooperate with the second shear body 200 to allow the first shear body 100 and the second shear body 200 to rotate relative to each other. During normal use, the locking mechanism 300 can be operated, and the locking mechanism 300 is not connected to the second shear body 200. At this time, the first shear body 100 and the second shear body 200 are normally pivotally connected, and the scissors are used normally. When it is necessary to lock the scissors, the locking mechanism 300 is operated, so that the locking mechanism 300, the second shear body 200, and the pivot 110 are connected together. Since the pivot 110 is fixedly connected to the first shear body 100, the second shear body 200 can be indirectly fixedly connected to the first shear body 100, so that the first shear body 100 and the second shear body 200 cannot be opened, which can reduce the occurrence of accidental injury to the user by the scissors.

[0031] Specifically, the handle of the scissors can be designed as a foldable mechanism. The handle can be folded and retracted. During the folding process, the user needs to apply force to the handle. Therefore, when operating the handle, the first scissor body 100 and the second scissor body 200 of the scissors are prone to accidentally opening, which may accidentally injure the user, which is quite dangerous. A locking mechanism 300 can be set at the pivot 110 of the first scissor body 100 and the second scissor body 200 to lock them. The locking mechanism 300 set at the pivot 110 can save space and the setting position is more reasonable. The pivot 110 can be fixedly connected to the first shear body 100. The pivot 110 can be connected to the first shear body 100 using a fastener 113, or the pivot 110 and the first shear body 100 can be integrally manufactured. The pivot 110 can move together with the first shear body 100. The locking mechanism 300 is disposed on the pivot 110. When the first shear body 100 and the second shear body 200 are sheared together, the locking mechanism 300 can engage and connect the pivot 110 to the first shear body 100. The connection method is not limited. The locking mechanism 300 is respectively connected to the pivot 110 and the first shear body 100. After the 00 is fixedly connected, since the pivot 110 is fixedly connected to the first shear body 100, the locking mechanism 300 indirectly fixes the first shear body 100 and the second shear body 200 together, so that the first shear body 100 and the second shear body 200 cannot be opened, thus achieving locking. After locking by operating the locking mechanism 300, the handle can be folded at will without accidentally injuring the user. When normal use is required, the locking mechanism 300 can be operated to prevent it from cooperating with the second shear body 200. The second shear body 200 is then released from the restriction and can rotate relative to the first shear body 100 for normal cutting.

[0032] It should be noted that when cutting thicker branches, the shears need to provide greater shearing force. The axis of the folding pivot of a conventional folding handle is generally parallel to the axis of the shears' pivot 110. Therefore, when applying force for shearing, the folding pivot needs to withstand radial shearing force. Ordinary folding pivots cannot bear large shearing forces, requiring high-strength metal processing, thus increasing manufacturing costs. This embodiment provides a lockable garden shears that can have a first handle 410, a second handle 420, and two folding pivots 430. The first handle 410 is pivotally connected to the first shear body 100 via one of its folding pivots 430. Similarly, the second handle 420 is pivotally connected to the second shear body 200 via the other folding pivot. The folding pivot 430 is pivotally connected, and the first handle 410 and the second handle 420 can rotate around the folding pivot 430. Furthermore, the axial direction of the folding pivot 430 can be perpendicular to the axial direction of the pivot 110. In this embodiment, during shearing, the folding pivot 430 bears the axial tensile force. Since the axial tensile force that the shaft can withstand is greater than the radial shearing force, a typical folding pivot 430 can ultimately provide a large shearing force to the scissors, resulting in lower manufacturing costs. However, such folding handles may cause the scissors to open during folding. Specifically, during folding, the direction of the force applied by the folding handle is inconsistent with the direction of the scissors' cutting action, which can easily cause the scissors to open, potentially injuring the user. Therefore, the locking mechanism 300 of this invention, in conjunction with this embodiment, solves both the strength problem of the folding pivot 430 and the problem of the scissors easily opening during folding.

[0033] Reference Figures 1 to 3 According to some embodiments of the present invention, the locking mechanism 300 includes a locking member 310, which is movably connected to one end of the pivot 110 near the second shear body 200. In the working state, the locking member 310 can engage with the pivot 110 so that the locking member 310 can rotate with the pivot 110. In the locked state, when the first shear body 100 and the second shear body 200 are engaged, the locking member 310 can engage with both the pivot 110 and the second shear body 200 to restrict the relative rotation between the first shear body 100 and the second shear body 200. By operating the locking member 310 to switch the usage state, it is convenient for the user to use.

[0034] Specifically, the locking member 310 can be movably connected to the end of the pivot 110 and is locked at the end of the pivot 110 near the second shear body 200. The locking mechanism 300 is located on one side of the second shear body 200. The locking member 310 can move relative to the pivot 110. In normal operation, the locking member 310 can move to be fixedly connected to the pivot 110. At this time, the locking member 310 rotates with the pivot 110 without affecting the movement of the second shear body 200, so that the scissors can work normally. In the locked state, the first shear body 100 and the second shear body 200 cut together, and the locking member 310 can move to be connected to the pivot 110 and the second shear body 200 together to realize the connection between the first shear body 100 and the second shear body 200. By operating the locking member 310, the usage state can be switched, which can facilitate the use of the user.

[0035] It should be noted that the locking member 310 is not limited to the above embodiment. It can also adopt other embodiments. For example, in the working state, the locking member 310 may not be fixedly connected to the pivot 110, and the locking member 310 may not be connected to the second shear body 200.

[0036] Reference Figures 1 to 3 According to some embodiments of the present invention, the locking member 310 is provided with a first connecting portion 320, the pivot 110 is provided with a second connecting portion 120 and a third connecting portion 130, and the second scissor body 200 is provided with a fourth connecting portion 210. In the working state, the first connecting portion 320 is connected to the third connecting portion 130, and in the locked state, the first connecting portion 320 is connected to the second connecting portion 120 and the fourth connecting portion 210. By switching the connection between the various connecting portions, the state of the scissors can be changed, which facilitates operation.

[0037] Specifically, the locking member 310 may be provided with a first connecting portion 320, and the pivot 110 may be provided with a second connecting portion 120 and a third connecting portion 130, allowing the locking member 310 to switch between connections. The second shear body 200 is provided with a fourth connecting portion 210. The specific connection relationship between the first connecting portion 320, the second connecting portion 120, the third connecting portion 130, and the fourth connecting portion 210 is not limited and can be a snap-fit ​​connection, a threaded connection, a magnetic connection, etc. By operating the locking member 310, the first connecting portion 320 can be selectively connected to other second connecting portions 120, third connecting portions 130, and fourth connecting portions 210. During normal use, the locking member... 310 can be moved to connect the first connecting part 320 and the third connecting part 130, so that the locking member 310 is connected to the pivot 110. At this time, the locking member 310 rotates with the pivot 110, and the first scissor 100 and the second scissor 200 cut normally. When it is necessary to fold the scissor handle, the scissors are closed, and the locking mechanism 300 is switched to the locked state. The locking member 310 can be moved to be fixedly connected to the second connecting part 120 and the fourth connecting part 210. At this time, the locking member 310, the pivot 110, the second scissor 200 and the first scissor 100 are fixedly connected to each other, so that the first scissor 100 and the second scissor 200 cannot be opened, thereby protecting the user.

[0038] Reference Figures 1 to 4 According to some embodiments of the present invention, the locking member 310 is provided with a rotating shaft 330, and the pivot 110 has a mating groove 331. The rotating shaft 330 is connected to the mating groove 331 so that the locking member 310 can rotate around the axis of the mating groove 331. When the first shear body 100 and the second shear body 200 are engaged, the fourth connecting part 210 can correspond to the second connecting part 120. In the working state, the locking member 310 can rotate to connect with the third connecting part 130. In the locked state, the locking member 310 can rotate to connect with both the second connecting part 120 and the fourth connecting part 210. By rotating the locking member 310, different connection relationships can be formed, thereby switching between the working state and the locked state. The operation is convenient, and the locking member 310 is located at the pivot 110, which saves space and does not hinder the normal use of the shears. The structure is arranged in a more reasonable manner.

[0039] Specifically, the rotating shaft 330 matches the shape of the mating groove 331, and is cylindrical. The rotating shaft 330 can be inserted into the mating groove 331 and can rotate within it. It is understood that there are certain limiting components to prevent the rotating shaft 330 from disengaging from the mating groove 331. This will not be described in detail here. The operator can rotate the locking member 310, and the first connecting part 320 will rotate along with it. The distances of the first connecting part 320, the second connecting part 120, the third connecting part 130, and the fourth connecting part 210 from the axis of the pivot 110 are basically the same. Therefore, rotating the locking member 310 allows... This allows the first connecting part 320 to rotate to the position corresponding to each connecting part. The operator can switch the connection object of the locking part 310 by rotating it to achieve state switching. The operation is simple. In specific use, the locking part 310 rotates to the third connecting part 130 and connects to it, which enables the scissors to be used normally. When cutting, the second connecting part 120 and the fourth connecting part 210 can be aligned. The first connecting part 320 can rotate to the second connecting part 120 and connect together with the second connecting part 120 and the fourth connecting part 210, thereby locking the first scissor body 100 and the second scissor body 200.

[0040] It should be noted that the locking member 310 is not limited to the above embodiment. It can also adopt other embodiments. For example, the locking member 310 may not have a rotating shaft 330, but may have a mating groove 331. The pivot 110 may be a rotating shaft 330. The locking member 310 can cooperate with the rotating shaft 330 of the pivot 110 through the mating groove 331, and the locking member can also rotate around the pivot 110.

[0041] Reference Figures 2 to 5 According to some embodiments of the present invention, a mating portion 111 is provided at one end of the pivot 110 near the rotating shaft 330. The mating portion 111 is located circumferentially around the pivot 110, and the second connecting portion 120 and the third connecting portion 130 are provided on the mating portion 111. By using the pivot 110 to provide the mating portion 111, its structure can be made more compact. Since the mating portion 111 does not require the addition of other structures for connection and fixation, the structure of the locking mechanism 300 is simpler and more compact.

[0042] Specifically, a mating part 111 can be provided at the end of the pivot 110 near the rotating shaft 330. The mating part 111 can be a mating component connected to the pivot 110. It is understood that the mating part 111 can also be integrally formed with the pivot 110. A second connecting part 120 and a third connecting part 130 can be provided on the mating part 111. The specific structure of the connecting part is not limited here. The mating part 111 is located in the circumference of the pivot 110. The second connecting part 120 and the third connecting part 130 are spaced apart on the mating part 111. The locking member 310 can rotate at different angles and selectively align the first connecting part 320 with the second connecting part 120 or the third connecting part 130. By using the pivot 110 to provide the mating part 111, its structure can be made more compact. The mating part 111 does not need to add other structures for connection and fixation, making the structure of the locking mechanism 300 simpler and more compact.

[0043] It is understood that the mating part 111 can also be provided on the first shear body 100, the second connecting part 120 and the third connecting part 130 can be provided on the first shear body 100, and the second shear body 200 is provided with a corresponding clearance space so that the locking member 310 can cooperate with the mating part 111.

[0044] Reference Figures 1 to 4 According to some embodiments of the present invention, the locking member 310 further includes an operating member 311 and a locking pin 312. The first connecting portion 320 is the locking pin 312. The rotating shaft 330 and the locking pin 312 are both disposed on the side of the operating member 311 near the pivot 110. The rotating shaft 330 can slide close to or away from the pivot 110 along the axial direction of the mating groove 331. The second connecting portion 120 is the first through hole 121, the third connecting portion 130 is the second through hole 131, and the fourth connecting portion 210 is the third through hole 211. In the working state, the locking pin 312 can be inserted into the second through hole 131. In the locked state, the locking pin 312 can pass through the first through hole 121 and be inserted into the third through hole 211. By pulling the locking member 310, it can be connected or disconnected from the connecting portion. The overall operation is simple and convenient for users.

[0045] Specifically, the operating element 311 is gripped by the user, while the locking pin 312 can be connected to the operating element 311 via fastener 113. It is understood that the locking pin 312 can also be integrally formed with the operating element 311. The locking pin 312 is located on one side of the rotating shaft 330, and the operating element 311 can rotate around the rotating shaft 330, allowing the locking pin 312 to rotate around the rotating shaft 330. That is, the first connecting part 320 can rotate, and the rotating shaft 330 is slidably engaged with the mating groove 331, which allows the rotating shaft 330 to slide along its axial direction. The movable travel channel allows the pivot 330 to slide, enabling the locking member 310 to move closer to or further away from the pivot 110. The first through hole 121 and the second through hole 131 are formed on the mating part 111, and the third through hole 211 is formed on the second shear body 200. During use, the locking member 310 can slide away from the pivot 110, allowing the locking pin 312 to rotate freely without being restricted by other structures. When needed, the locking member 310 can be rotated until the locking pin 312 aligns with the second through hole 131, and then the locking member... 310 slides close to the pivot 110, causing the locking pin 312 to insert into the second through hole 131. The second through hole 131 restricts the locking pin 312 from rotating around the pivot 330, and the locking member 310 can rotate together with the mating part 111 when it rotates, without affecting the normal use of the scissors. When locking is required, the locking member 310 can be moved away from the pivot 110 first, disengaging the locking pin 312 from the second through hole 131. Then, the locking member 310 can be rotated so that the locking pin 312 can rotate to align with the first through hole 121, and the first scissor body 100 and... When the second shear body 200 is engaged, the first through hole 121 and the third through hole 211 can be aligned. After the locking member 310 is rotated into place, it can slide close to the pivot 110. The locking pin 312 is inserted into the first through hole 121 and the third through hole 211. The locking pin 312 can simultaneously connect the mating part 111 to the second shear body 200, thereby indirectly connecting the first shear body 100 and the second shear body 200. By pulling the locking member 310 to slide, it can be engaged or disengaged from the connecting part. The overall operation is simple and convenient for users.

[0046] Reference Figures 3 to 4 According to some embodiments of the present invention, the locking post 312 includes a first post segment 312A and a second post segment 312B. The first post segment 312A is disposed on the operating member 311, and the second post segment 312B is disposed at the end of the first post segment 312A away from the operating member 311. The minimum diameter of the second post segment 312B is smaller than the minimum diameter of the first post segment 312A, and the minimum diameter of the second through hole 131 is smaller than the maximum diameter of the first post segment 312A.

[0047] Specifically, the locking post 312 can be provided with two stepped sections. The first post section 312A can be set to be larger, and the diameter of the second post section 312B can be set to be smaller than that of the first post section 312A. Therefore, a structure similar to a shoulder can be created. The diameter of the second through hole 131 is smaller than that of the first post section 312A. Therefore, the first post section 312A cannot pass through the second through hole 131. The length of the second post section 312B is smaller than the thickness of the second through hole 131. Therefore, the second post section 312B will not pass through the mating part 111 and will not affect the normal shearing of the first shear body 100 and the second shear body 200. In the working state, when the locking member 310 is operated to approach the pivot 110, the first segment 312A of the locking pin 312 can restrict the locking pin 312 so that it is not over-inserted into the second through hole 131. The first segment 312A can be in the second through hole 131 without passing through the second through hole 131, and the side wall of the first segment 312A and the second through hole 131 form a connection restriction.

[0048] It should be noted that the locking post 312 is not limited to the above embodiment. Other embodiments can also be adopted. For example, a protruding limiting member can be provided on the locking post 312 in the circumferential direction. The limiting member cannot pass through the second through hole 131, so as to restrict the movement of the locking post 312.

[0049] Reference Figures 3 to 5 According to some embodiments of the present invention, the locking member 310 is provided with a positioning block 313 and the mating part 111 is provided with a relief groove 112. In the locked state, the positioning block 313 can be rotated to engage with the relief groove 112 so that the locking pin 312 can be inserted into the third through hole 211. In the working state, the positioning block 313 abuts against the mating part 111 to prevent the locking pin 312 from passing through the second through hole 131.

[0050] Specifically, the positioning block 313 can be integrally set with the locking member 310. The positioning block 313 can protrude towards the mating part 111, and the mating part 111 is provided with a relief groove 112 that can accommodate the positioning block 313. In the locked state, when the locking member 310 rotates to the point where the locking pin 312 is aligned with the first through hole 121, the positioning block 313 is also aligned with the relief groove 112, and the positioning block 313 can be pressed into the relief groove 112, so that the locking pin 312 can be inserted into place. In the working state, when the locking member 310 rotates to another position, the positioning block 313 cannot be aligned with the relief groove 112. Therefore, the lower end of the positioning block 313 can only abut against the mating part 111, and the locking member 310 as a whole cannot be pressed down, so that the locking pin 312 will not pass through the second through hole 131, ensuring that the scissors can work normally.

[0051] It is understandable that the locking member 310 may not have a positioning block 313, but may have a groove. The mating part 111 may also have a protruding positioning block 313, which is inserted into the groove to form a restrictive fit.

[0052] According to some embodiments of the present invention, a first elastic member 340 is provided between the locking member 310 and the pivot 110, and the first elastic member 340 can drive the locking member 310 to move closer to the pivot 110. The first elastic member 340 can drive the locking member 310 to press against the corresponding through hole, which facilitates operation by the operator.

[0053] Reference Figures 2 to 3 Specifically, a first elastic element 340 can be provided between the locking member 310 and the pivot 110. The first elastic element 340 can be a spring. The elastic force of the spring can drive the locking member 310 to press against the pivot 110. When the user operates, pulling the locking member 310 can compress the first elastic element 340. After rotating the locking member 310 to the position, the first elastic element 340 can drive the locking pin 312 of the locking member 310 to press against the corresponding through hole, which can facilitate operation.

[0054] It should be noted that the first elastic element 340 is not limited to the above embodiment, and it can also adopt other embodiments. For example, the first elastic element 340 can also be a tension spring. One end of the tension spring can be connected to the locking element 310, and the other end can be connected to the pivot 110. The locking element 310 can be pulled toward the pivot 110 by the tension spring.

[0055] Reference Figures 2 to 3 According to some embodiments of the present invention, the locking member 310 is further provided with a mounting groove 314, the bottom wall of the mounting groove 314 is provided with a mounting hole 315, the pivot 110 is provided with a fastener 113, the fastener 113 passes through the mounting hole 315 and is connected to the pivot 110, one end of the first elastic member 340 abuts against the bottom wall and the other end abuts against the fastener 113.

[0056] Specifically, the locking member 310 can be provided with a cylindrical mounting groove 314, and the bottom wall of the mounting groove 314 can be provided with a mounting hole 315, which communicates with the pivot 110. The fastener 113 can be a bolt, which passes through the mounting hole 315. The end of the pivot 110 can be provided with a threaded hole, and the bolt can be threaded to it. The maximum diameter of the bolt head can be larger than the mounting hole 315. The first elastic member 340 can be a spring, with one end abutting against the head of the bolt and the other end abutting against the bottom wall of the mounting groove 314. When the locking member 310 is pulled, the bottom wall of the mounting groove 314 moves relative to the fastener 113, causing the spring to be compressed. After the locking member 310 is rotated into place, simply release the hand, and the compressed spring can drive the locking member 310 to press against the mating part 111, realizing the connection. With the above structure, the operation steps can be simplified and it is easy to use.

[0057] It should be noted that the first elasticity is not limited to the above embodiments, and it can also adopt other embodiments. For example, the first elastic element 340 can also be an elastic element such as silicone or rubber.
