Description

Technical Field

[0001] The present invention relates to the technical field of gardening tools, in particular to a pair of gardening shears. Background Art

[0002] Gardening shears are a type of gardening tool specifically used for pruning plant tissue, such as branches and leaves. They typically consist of two hinged blades and a handle connected to the blades. The blades and handles are essentially located in the same plane. The user manipulates the handles with both hands, rotating the blades open and close to cut plant tissue. During pruning, due to the varying growth directions of plant branches and the varying pruning requirements, the user needs to adjust the orientation of the shears. For example, in a first operating condition, the shears are located in a horizontal plane; in a second operating condition, the shears are located in a vertical plane; and in a third operating condition, the shears are located at an angle to the horizontal plane.

[0003] From the perspective of ergonomics, in the first working condition, the method of applying force with both hands is labor-saving and comfortable, while in the second and third working conditions, it is labor-intensive and brings certain inconvenience to the user, reducing the user's comfort.

[0035] Reference Figure 1 、 Figure 2 and Figure 3 , a gardening shears, which includes a main body mechanism 100, a blade assembly 200 and a handle assembly 300, the main body mechanism 100 is provided with a transmission structure, the blade assembly 200 is rotatably connected to the main body mechanism 100 and includes a first blade 210 and a second blade 220, the first blade 210 and the second blade 220 are hingedly matched and are both transmission-connected to the transmission structure, the handle assembly 300 is connected to the main body mechanism 100 and includes a first handle 310 and a second handle 320, the first handle 310 and the second handle 320 are distributed along the left and right directions and are hingedly matched therebetween, the first handle 310 and the second handle 320 are both transmission-connected to the transmission structure, and the first blade 210 and the second blade 220 can be driven by the transmission structure to rotate relative to each other to open and close, and the blade assembly 200 can rotate relative to the main body mechanism 100 to change the shearing direction between the first blade 210 and the second blade 220.

[0036] It is understandable that if Figure 1 、 Figure 2 and Figure 3 As shown, the blade assembly 200 is rotatably connected to the main body 100, and its rotation axis relative to the main body 100 is parallel to the front-back direction. The blade assembly 200 also includes a first hinge shaft 230, and the first blade 210 and the second blade 220 are hingedly matched through the first hinge shaft 230. Figure 1 and Figure 2 In the embodiment, the axis direction of the first hinge shaft 230 is parallel to the up-down direction, and the first blade 210 and the second blade 220 rotate relative to each other in the horizontal direction to open and close; the handle assembly 300 also includes a second hinge shaft 330, and the first handle 310 and the second handle 320 are hinged together through the second hinge shaft 330. Figure 1 and Figure 2 In the embodiment, the axis direction of the second hinge shaft 330 is parallel to the up-down direction, and the first handle 310 and the second handle 320 can rotate relative to each other in the horizontal direction.

[0037] When you need to adjust the cutting direction of the blade according to the pruning requirements, for example, when you need to prune the plant tissue in the up and down direction, refer to Figure 1 and Figure 8The blade assembly 200 can be rotated 90 degrees relative to the main body 100, thereby changing the cutting direction between the first blade 210 and the second blade 220, causing the blade portions of the first blade 210 and the second blade 220 to open and close longitudinally. At this time, the position of the handle assembly 300 relative to the main body 100 remains unchanged, and the first handle 310 and the second handle 320 remain distributed in the left and right directions. The user's left and right hands can respectively operate the first handle 310 and the second handle 320, and both hands apply force in the left and right directions to drive the two handles to rotate relative to each other. The first handle 310 and the second handle 320 drive the first blade 210 and the second blade 220 to rotate and open relative to each other through the transmission structure of the main body 100, so that the blades cut the plant tissue in the vertical direction. The above structure can change the cutting direction of the two blades while keeping the two handles distributed left and right. Therefore, when meeting different pruning needs, the user's hands can still apply force in the left and right directions to operate the two handles to rotate, meeting ergonomic design and improving user comfort.

[0038] In actual application, the specific structures of the main body mechanism 100, the blade assembly 200 and the handle assembly 300 can be set accordingly according to actual use needs, and will not be described in detail here. A detailed explanation will be given below.

[0039] In some embodiments, the main body mechanism 100 includes a main housing 110, the blade assembly 200 includes a first housing base 240, the first blade 210 and the second blade 220 are both provided on the first housing base 240, the first housing base 240 is rotatably connected to the main housing 110, the transmission structure includes a main rotating member 120, a first transmission member 130 and a first rotating seat 150, the main rotating member 120 and the first rotating seat 150 are both rotatably connected to the main housing 110, the main rotating member 120, the first rotating seat 150 and the first housing base 240 are collinear with respect to the rotation axis of the main housing 110, The first rotating seat 150 can rotate relative to the main shell body 110 together with the first shell seat 240. The main rotating member 120 is respectively connected to the first handle 310 and the second handle 320, and can be driven to rotate by the first handle 310 and the second handle 320. The first transmission member 130 is rotatably connected to the first rotating seat 150 and is engaged with the main rotating member 120 through a bevel gear structure. The first transmission member 130 is respectively connected to the first blade 210 and the second blade 220, and can drive the first blade 210 and the second blade 220 to rotate relative to each other and open and close.

[0040] It is understandable that if Figure 3 、 Figure 4 and Figure 5As shown, the first blade 210 and the second blade 220 are both arranged on the first shell seat 240, and the blade assembly 200 is rotatably connected to the main shell body 110 through the first shell seat 240. The main rotating member 120 and the first rotating seat 150 are both rotatably connected to the main shell body 110, and the main rotating member 120, the first rotating seat 150 and the first shell seat 240 are collinear with the rotation axis of the main shell body 110. A bevel gear structure is provided on the front side of the main rotating member 120, the first transmission member 130 is rotatably connected to the first rotating seat 150 and is meshed with the main rotating member 120 through a bevel gear structure. The rear side of the main rotating member 120 is respectively connected to the first handle 310 and the second handle 320, and the first transmission member 130 is respectively connected to the first blade 210 and the second blade 220. When in use, the first handle 310 and the second handle 320 cooperate to drive the main rotating member 120 to rotate, the main rotating member 120 drives the first transmission member 130 to rotate and the first transmission member 130 drives the first blade 210 and the second blade 220 to rotate and open and close relative to each other, thereby realizing the linkage between the handle and the blade; when adjusting the rotating blade assembly 200, the first shell seat 240 rotates relative to the main shell 110 and drives the first rotating seat 150 to rotate together, and the first transmission member 130 moves with the first rotating seat 150. Since the rotation axes are collinear and the main rotating member 120 and the first transmission member 130 are engaged with the bevel gear structure, after the position adjustment of the first shell seat 240 and the first rotating seat 150 is completed, the main rotating member 120 and the first transmission member 130 maintain a transmission relationship, thereby being able to continue to realize the linkage between the handle and the blade, so that the first blade 210 and the second blade 220 are moved. Figure 1 The status shown and Figure 8 In the state shown, the first handle 310 and the second handle 320 can be driven to rotate relative to each other to open and close, which is convenient for use.

[0041] In actual application, in addition to the above structure, the transmission structure may also include a cross-axis universal coupling, which is used to replace the transmission between the main rotating member 120 and the first transmission member 130. One end of the cross-axis universal coupling is connected to the two handles, and the other end is connected to the two blades to realize the transmission of different rotation axes. Of course, in addition to the cross-axis universal coupling, other types of universal couplings can also be replaced according to the actual transmission situation, and the specific changes can be made according to actual usage needs.

[0042] In some embodiments, the transmission structure also includes a second transmission member 140, the second transmission member 140 is provided with a first straight gear 141, the first blade 210 is provided with a first tooth portion 211, and the second blade 220 is provided with a second tooth portion 221. The first tooth portion 211 and the second tooth portion 221 are both engaged with the first straight gear 141, and the engagement position of the first tooth portion 211 and the engagement position of the second tooth portion 221 are respectively located on opposite sides of the first straight gear 141. The first transmission member 130 can drive the second transmission member 140 to rotate.

[0043] It is understandable that if Figures 2 to 5 as well as Figure 7 、 Figure 8 As shown, the first transmission member 130 can be linked with the second transmission member 140, thereby driving the second transmission member 140 to rotate, and the second transmission member 140 is provided with a first straight gear 141, and the first blade 210 is provided with a first tooth portion 211, the first tooth portion 211 is engaged with the first straight gear 141 for transmission, and the meshing position is located on the front side of the first straight gear 141, and the second blade 220 is provided with a second tooth portion 221, the second tooth portion 221 is engaged with the first straight gear 141 for transmission, and the meshing position is located on the rear side of the first straight gear 141, so that when the second transmission member 140 rotates, the first straight gear 141 can drive the first tooth portion 211 and the second tooth portion 221 to rotate in opposite directions, so that the blades of the first blade 210 and the blades of the second blade 220 are rotated to open or close, thereby realizing that the rotation of the first transmission member 130 drives the two blades to rotate relative to each other to open and close, and its structure is simple and easy to use.

[0044] In actual application, in addition to the above structure, a spur gear structure can be provided on the first transmission member 130, and a spur gear member meshing with it can be provided. The first tooth portion 211 and the second tooth portion 221 are respectively meshed with the spur gear structure on the first transmission member 130 and the spur gear member. Since the first transmission member 130 and the spur gear member have opposite rotation directions, the rotation directions of the first tooth portion 211 and the second tooth portion 221 can also be opposite, thereby driving the two blades to rotate relative to each other to open and close; the first transmission member 130 and the second transmission member 140 can be directly fixed to each other through a clamping structure or a plug-in structure to achieve linkage, or the two can also be transmitted through a gear structure to achieve linkage, and the specific changes can be made according to actual usage needs.

[0045] In some embodiments, a first clutch structure is provided between the first transmission member 130 and the second transmission member 140 , and the first clutch structure can enable the first transmission member 130 and the second transmission member 140 to be linked or delinked.

[0046] It is understandable that by setting the first clutch structure, when the rotating blade assembly 200 needs to be adjusted, the first clutch structure decouples the first transmission member 130 and the second transmission member 140. At this time, the rotation of the first transmission member 130 cannot drive the second transmission member 140 to rotate. Therefore, when the first rotating seat 150 drives the first transmission member 130 to rotate, the self-rotation of the first transmission member 130 generated by the engagement with the main rotating member 120 through the bevel gear structure will not be transmitted to the second transmission member 140, and the first blade 210 and the second blade 220 can remain in a closed state when the blade assembly 200 rotates, ensuring that the state of the blade is consistent with the state of the handle; after completing the position adjustment of the blade assembly 200, the first clutch structure couples the first transmission member 130 and the second transmission member 140, so that the rotation of the first transmission member 130 can be transmitted to the blade assembly 200 to control the relative rotation and opening and closing of the two blades.

[0047] In actual application, in addition to setting the first clutch structure, the second transmission member 140 can also be set to be detachable. When the first transmission member 130 and the second transmission member 140 need to be linked, the second transmission member 140 is installed and connected to the first transmission member 130. When the linkage needs to be released, the second transmission member 140 is disassembled and removed, thereby preventing the first blade 210 and the second blade 220 from being driven to rotate by the first transmission member 130 when the blade assembly 200 rotates. The specific setting can be made according to actual usage needs.

[0048] Specifically, a first knob 250 is provided on the first shell base 240, and the first knob 250 has a first connecting shaft 251. The first rotating base 150 is correspondingly provided with a first connecting hole 151. The first connecting shaft 251 is partially inserted into the first connecting hole 151 and threadedly engaged with the first connecting hole 151. The second transmission member 140 is rotatably connected to the first connecting shaft 251 and can move with the first knob 250. The first clutch structure includes a first linkage tooth 132 provided on the first transmission member 130 and a second linkage tooth 143 provided on the second transmission member 140. The first linkage tooth 132 can cooperate with the second linkage tooth 143 to link the first transmission member 130 with the second transmission member 140. The first knob 250 can rotate and move relative to the first rotating base 150 through the threaded engagement between the first connecting shaft 251 and the first connecting hole 151, so as to drive the second transmission member 140 to move relative to the first transmission member 130, so that the first linkage tooth 132 and the second linkage tooth 143 are engaged or separated.

[0049] It is understandable that if Figure 3 、 Figure 5 and Figure 7As shown, the first transmission member 130 is provided with a first protrusion 131, and the second transmission member 140 is correspondingly provided with a first recessed position 142 for the first protrusion 131 to be inserted, the first linkage tooth 132 is provided on the first protrusion 131, and the second linkage tooth 143 is provided in the first recessed position 142, the second transmission member 140 is rotatably clamped on the lower part of the first connecting shaft 251, and the upper part of the first connecting shaft 251 is inserted into the first connecting hole 151 and threadedly engaged with the first connecting hole 151. When the linkage needs to be released, the first knob 250 can be operated and rotated. Through the threaded engagement between the first connecting shaft 251 and the first connecting hole 151, the first knob 250 will be displaced downward and drive the second transmission member 140 downward, so that the first linkage tooth 132 and the second linkage tooth 143 are separated, thereby releasing the linkage between the first transmission member 130 and the second transmission member 140. When the linkage between the two is required, the first knob 250 can be reset and rotated. Through the threaded engagement between the first connecting shaft 251 and the first connecting hole 151, the first knob 250 will be moved upward and reset, and drive the second transmission member 140 upward, so that the first linkage tooth 132 and the second linkage tooth 143 are engaged, thereby resetting the linkage between the first transmission member 130 and the second transmission member 140. The above-mentioned clutch structure is simple and reasonable, and is easy to operate and use.

[0050] In actual application, the first linkage tooth 132 and the second linkage tooth 143 can be a face gear structure, a bevel gear structure or a spline structure, and in addition to the above structures, the first clutch structure can also be realized by a pin structure. For example, a special-shaped pin that can move up and down is provided on the second transmission member 140, and a socket that cooperates with the special-shaped pin is provided on the first transmission member 130. A button is provided on the first shell seat 240, and the button is used to control the up and down movement of the special-shaped pin. When the special-shaped pin is inserted into the socket, the second transmission member 140 is linked with the first transmission member 130. When the special-shaped pin leaves the socket, the two are released from linkage to realize clutch control. The specific settings can be made according to actual usage needs.

[0051] In some embodiments, a first locking structure is provided between the first shell seat 240 and the main shell 110 and / or between the first rotating seat 150 and the main shell 110. The first locking structure can limit the rotation of the first shell seat 240 and the first rotating seat 150 relative to the main shell 110 or release the restriction.

[0052] It is understandable that by setting the first locking structure, when the rotating blade assembly 200 needs to be adjusted, the first locking structure releases the rotation restriction of the first shell seat 240 and the first rotating seat 150 relative to the main shell 110. At this time, the blade assembly 200 can be rotated relative to the main body 100 to adjust the position; after the position adjustment of the blade assembly 200 is completed, the first locking structure restricts the rotation of the first shell seat 240 and the first rotating seat 150 relative to the main shell 110, thereby realizing the position locking of the blade assembly 200 after rotation, reducing the possibility of its loosening and deflection, and facilitating use.

[0053] In actual application, in addition to setting the first locking structure, the matching dimensions between the first shell seat 240 and the main shell 110 can also be designed so that after the blade assembly 200 is adjusted to the position, the interference fit between the first shell seat 240 and the main shell 110 is utilized to generate a larger rotational resistance, so as to achieve the fixed position of the blade assembly 200 after rotation. The specific setting can be made according to actual usage needs.

[0054] Specifically, the first locking structure includes a second connecting shaft 111 and a first locking block 152. The second connecting shaft 111 is arranged on the main shell 110. The first rotating seat 150 is rotatably connected to the main shell 110 through the second connecting shaft 111. The first locking block 152 is movably arranged on the first rotating seat 150. The first connecting shaft 251 can cooperate with the first locking block 152 to press the first locking block 152 on the second connecting shaft 111 or release the pressure.

[0055] It is understandable that if Figure 3 、 Figure 5 and Figure 7As shown, the second connecting shaft 111 is inserted into the first rotating seat 150, the first locking block 152 is slidably connected to the first rotating seat 150 and can move up and down, the first locking block 152 is located on the upper side of the first connecting hole 151, and the upper end of the first connecting shaft 251 can pass through the first connecting hole 151 and contact the first locking block 152. When it is necessary to restrict the rotation of the first rotating seat 150 relative to the main housing 110, the first knob 250 is tightened, so that the upper portion of the first connecting shaft 251 pushes the first locking block 152 upward and the first locking block 152 is pressed onto the second connecting shaft 111, thereby restricting the rotation of the first rotating seat 150 and simultaneously restricting the rotation of the first housing 240 that rotates therewith; when it is necessary to release the rotation restriction, the first knob 250 is loosened, so that the first connecting shaft 251 moves downward, thereby releasing the push on the first locking block 152 and the pressure between the first locking block 152 and the second connecting shaft 111, so that the first rotating seat 150 can rotate relative to the main housing 110. The above structure is simple. By rotating the first knob 250, the clutch control between the first transmission member 130 and the second transmission member 140 is realized, and the locking control between the first rotating seat 150 and the main housing 110 is realized, which is convenient for operation and use.

[0056] In actual application, teeth and grooves can be set between the first locking block 152 and the second connecting shaft 111 to achieve a better rotation restriction effect, or an anti-slip structure can be set; in addition to the above structure, the first locking structure can also be a bolt set on the first shell seat 240. By tightening or loosening the bolt, the bolt or the first shell seat 240 is pressed on the main shell 110 or the pressure is released, thereby achieving rotation restriction or releasing the rotation restriction of the first shell seat 240, thereby limiting the rotation of the first rotating seat 150 or releasing the restriction. The specific structure can also be changed accordingly according to actual use needs.

[0057] In some embodiments, the handle assembly 300 is rotatably connected to the main body 100 , and the rotation axis of the blade assembly 200 relative to the main body 100 and the rotation axis of the handle assembly 300 relative to the main body 100 are perpendicular to each other.

[0058] It is understandable that if Figure 1 、 Figure 2 and Figure 3As shown, the handle assembly 300 is rotatably connected to the main body 100, with its rotation axis parallel to the left-right direction and perpendicular to the rotation axis of the blade assembly 200 relative to the main body 100. Therefore, during use, the main body 100 can be operated to rotate relative to the handle assembly 300, thereby further adapting to different pruning needs, such as pruning high plants or low plants, thereby improving adaptability. In actual application, in addition to the above structure, the handle assembly 300 can also be fixed to the main body 100, with only the blade assembly 200 being rotatable relative to the main body 100. The specific setting can be set accordingly according to actual use needs.

[0059] In some embodiments, the main body mechanism 100 includes a main housing 110, the handle assembly 300 includes a second housing 340, the first handle 310 and the second handle 320 are both provided on the second housing 340, the second housing 340 is rotatably connected to the main housing 110, the transmission structure includes a secondary rotating member 160, a third transmission member 170 and a second rotating seat 190, the secondary rotating member 160 and the second rotating seat 190 are both rotatably connected to the main housing 110, and the secondary rotating member 160, the second rotating seat 190 and the second housing 340 are collinear with respect to the rotation axis of the main housing 110 The second rotating seat 190 can rotate relative to the main shell 110 together with the second shell seat 340. The third transmission member 170 is rotatably connected to the second rotating seat 190 and is engaged with the auxiliary rotating member 160 through a bevel gear structure. The third transmission member 170 is respectively connected to the first handle 310 and the second handle 320, and can be driven to rotate by the first handle 310 and the second handle 320. The auxiliary rotating member 160 is respectively connected to the first blade 210 and the second blade 220, and can drive the first blade 210 and the second blade 220 to rotate relative to each other and open and close.

[0060] It is understandable that if Figure 3 、 Figure 4 and Figure 5As shown, the first handle 310 and the second handle 320 are both provided on the second shell base 340, and the handle assembly 300 is rotatably connected to the main shell 110 through the second shell base 340. The auxiliary rotating member 160 and the second rotating seat 190 are both rotatably connected to the main shell 110, and the auxiliary rotating member 160, the second rotating seat 190 and the second shell base 340 are collinear with the rotation axis of the main shell 110. The auxiliary rotating member 160 is provided with a bevel gear structure, and the third transmission member 170 is rotatably connected to the second rotating seat 190. Both the third transmission member 170 and the main rotating member 120 are meshed with the auxiliary rotating member 160 through the bevel gear structure. Thus, the auxiliary rotating member 160 can be respectively connected to the first blade 210 and the second blade 220 through the main rotating member 120, and the third transmission member 170 is respectively connected to the first handle 310 and the second handle 320. When in use, the first handle 310 and the second handle 320 rotate relative to each other to open and close, thereby driving the third transmission member 170 to rotate, the third transmission member 170 drives the auxiliary rotating member 160 to rotate, and the auxiliary rotating member 160 drives the main rotating member 120 to rotate, thereby driving the first blade 210 and the second blade 220 to rotate relative to each other to open and close, realizing the linkage between the handle and the blade; when adjusting the rotating handle assembly 300, the second shell seat 340 rotates relative to the main shell 110 and drives the second rotating seat 190 to rotate together, and the third transmission member 170 As the second rotating seat 190 moves, since the rotation axes are collinear and the auxiliary rotating member 160 and the third transmission member 170 are engaged through the bevel gear structure, after the position adjustment of the second shell seat 340 and the second rotating seat 190 is completed, the auxiliary rotating member 160 and the third transmission member 170 maintain a transmission relationship, thereby continuing to realize the linkage between the handle and the blade, so that after the handle assembly 300 adjusts the rotation position, the two blades can still be driven to rotate and open and close relative to each other through the first handle 310 and the second handle 320, which is convenient for use.

[0061] In actual application, in addition to the above structure, the transmission structure may also include a cross-axis universal coupling, which is used to replace the transmission between the auxiliary rotating member 160 and the third transmission member 170. One end of the cross-axis universal coupling is connected to the two handles, and the other end is connected to the main rotating member 120 to realize the transmission of different rotation axes. The specific configuration can be changed according to actual usage needs.

[0062] In some embodiments, the transmission structure also includes a fourth transmission member 180, the fourth transmission member 180 is provided with a second spur gear 181, the first handle 310 is provided with a third tooth portion 311, and the second handle 320 is provided with a fourth tooth portion 321. The third tooth portion 311 and the fourth tooth portion 321 are both engaged with the second spur gear 181, and the engagement position of the third tooth portion 311 and the engagement position of the fourth tooth portion 321 are respectively located on opposite sides of the second spur gear 181. The fourth transmission member 180 can drive the third transmission member 170 to rotate.

[0063] It is understandable that if Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 8 As shown, the fourth transmission member 180 can be linked with the third transmission member 170, thereby driving the third transmission member 170 to rotate, the fourth transmission member 180 is provided with a second spur gear 181, the first handle 310 is provided with a third tooth portion 311, the third tooth portion 311 is engaged with the second spur gear 181 for transmission, and the meshing position is located at the front side of the second spur gear 181, the second handle 320 is provided with a fourth tooth portion 321, the fourth tooth portion 321 is engaged with the second spur gear 181 for transmission, and the meshing position is located at the rear side of the second spur gear 181, so that when the first handle 310 and the second handle 320 are relatively rotated to open and close, the third tooth portion 311 and the fourth tooth portion 321 cooperate to drive the second spur gear 181 to rotate, thereby driving the fourth transmission member 180 to rotate, and through subsequent transmission, the first blade 210 and the second blade 220 are driven to rotate relative to each other to open and close, thereby realizing that the two blades are driven to rotate relative to each other by the rotation of the first handle 310 and the second handle 320. Its structure is simple and easy to use.

[0064] In actual application, in addition to the above structure, a gear can be set on the second hinge shaft 330 between the first handle 310 and the second handle 320. One of the first handle 310 and the second handle 320 drives the second hinge shaft 330 to rotate, and the second hinge shaft 330 drives the gear to rotate and drives the third transmission member 170 to rotate through the gear, thereby inputting power through the handle and driving the third transmission member 170 to rotate; the third transmission member 170 and the fourth transmission member 180 can be directly fixed relative to each other through a clamping structure or a plug-in structure to achieve linkage, or the two can also be transmitted through a gear structure to achieve linkage, and the specific changes can be made according to actual usage needs.

[0065] In some embodiments, a second clutch structure is provided between the third transmission member 170 and the fourth transmission member 180 , and the second clutch structure can enable the third transmission member 170 and the fourth transmission member 180 to be linked or decoupled.

[0066] It is understandable that by setting the second clutch structure, when the rotating handle assembly 300 needs to be adjusted, the second clutch structure decouples the third transmission member 170 from the fourth transmission member 180. At this time, the rotation of the third transmission member 170 cannot drive the fourth transmission member 180 to rotate. Therefore, when the second rotating seat 190 drives the third transmission member 170 to rotate, the self-rotation of the third transmission member 170 generated by the engagement with the auxiliary rotating member 160 through the bevel gear structure will not be transmitted to the fourth transmission member 180. The first handle 310 and the second handle 320 can remain in a closed state when the handle assembly 300 rotates, ensuring that the state of the handle is consistent with the state of the blade; after completing the position adjustment of the handle assembly 300, the second clutch structure couples the third transmission member 170 and the fourth transmission member 180, so that the fourth transmission member 180 can drive the third transmission member 170 to rotate, so as to realize power input and subsequent power transmission, which is easy to use.

[0067] In actual application, in addition to setting up the second clutch structure, the fourth transmission member 180 can also be set to be detachable. When the third transmission member 170 and the fourth transmission member 180 need to be linked, the fourth transmission member 180 is installed and connected to the third transmission member 170. When the linkage needs to be released, the fourth transmission member 180 is disassembled and removed, thereby preventing the two handles of the handle assembly 300 from being driven to rotate by the third transmission member 170 when rotating. The specific setting can be made according to actual usage needs.

[0068] Specifically, a second knob 350 is provided on the second shell base 340, and the second knob 350 has a third connecting shaft 351. The second rotating base 190 is correspondingly provided with a second connecting hole 191. The third connecting shaft 351 is partially inserted into the second connecting hole 191 and threadedly engaged with the second connecting hole 191. The fourth transmission member 180 is rotatably connected to the third connecting shaft 351 and can move with the second knob 350. The second clutch structure includes a third linkage tooth 172 provided on the third transmission member 170 and a fourth linkage tooth 183 provided on the fourth transmission member 180. The third linkage tooth 172 can cooperate with the fourth linkage tooth 183 to link the third transmission member 170 with the fourth transmission member 180. The second knob 350 can rotate and move relative to the second rotating base 190 through the threaded engagement between the third connecting shaft 351 and the second connecting hole 191, so as to drive the fourth transmission member 180 to move relative to the third transmission member 170, so that the fourth linkage tooth 183 cooperates with or separates from the third linkage tooth 172.

[0069] It is understandable that if Figure 3 、 Figure 5 and Figure 6As shown, the third transmission member 170 is provided with a second protrusion 171, and the fourth transmission member 180 is correspondingly provided with a second recessed position 182 for the second protrusion 171 to be inserted, the third linkage tooth 172 is provided on the second protrusion 171, and the fourth linkage tooth 183 is provided in the second recessed position 182, and the fourth transmission member 180 is rotatably clamped on the upper part of the third connecting shaft 351, and the lower part of the third connecting shaft 351 is inserted into the second connecting hole 191 and threadedly engaged with the second connecting hole 191. When the linkage needs to be released, the second knob 350 can be operated and rotated. Through the threaded engagement between the third connecting shaft 351 and the second connecting hole 191, the second knob 350 will be displaced upward and drive the fourth transmission member 180 upward, so that the fourth linkage tooth 183 is separated from the third linkage tooth 172, thereby releasing the linkage between the fourth transmission member 180 and the third transmission member 170. When the linkage between the fourth transmission member 180 and the third transmission member 170 needs to be restored, the second knob 350 can be reset and rotated. Through the threaded engagement between the third connecting shaft 351 and the second connecting hole 191, the second knob 350 will be moved downward and reset, and drive the fourth transmission member 180 downward, so that the fourth linkage tooth 183 is engaged with the third linkage tooth 172, thereby resetting the linkage between the fourth transmission member 180 and the third transmission member 170. The above-mentioned clutch structure is simple and reasonable, and is easy to operate and use.

[0070] In actual application, the third linkage tooth 172 and the fourth linkage tooth 183 can be a face gear structure, a bevel gear structure or a spline structure, and in addition to the above structure, the second clutch structure can also be realized by a pin structure. For example, a special-shaped pin that can move up and down is provided on the fourth transmission member 180, and a socket that cooperates with the special-shaped pin is provided on the third transmission member 170. The specific pin clutch control method can be understood by referring to the above-mentioned pin structure in the expansion of the first clutch structure, and will not be repeated here.

[0071] In some embodiments, a second locking structure is provided between the second shell seat 340 and the main shell 110 and / or between the second rotating seat 190 and the main shell 110. The second locking structure can limit the rotation of the second shell seat 340 and the second rotating seat 190 relative to the main shell 110 or release the restriction.

[0072] It is understandable that by setting up a second locking structure, when the handle assembly 300 needs to be adjusted, the second locking structure releases the rotation restriction of the second shell seat 340 and the second rotating seat 190 relative to the main shell 110. At this time, the handle assembly 300 can be rotated relative to the main body mechanism 100 to adjust the position; after the position adjustment of the handle assembly 300 is completed, the second locking structure restricts the rotation of the second shell seat 340 and the second rotating seat 190 relative to the main shell 110, thereby realizing the position locking of the handle assembly 300 after rotation, reducing the possibility of it loosening and deflecting, and facilitating use.

[0073] In actual application, in addition to setting up the second locking structure, the matching dimensions between the second shell seat 340 and the main shell 110 can also be designed so that after the handle assembly 300 is adjusted to the position, the interference fit between the handle assembly 300 and the main shell 110 can be used to generate a larger rotational resistance to achieve the fixed position of the handle assembly 300 after rotation. The specific setting can be made according to actual usage needs.

[0074] Specifically, the second locking structure includes a fourth connecting shaft 112 and a second locking block 192. The fourth connecting shaft 112 is arranged on the main shell 110. The second rotating seat 190 is rotatably connected to the main shell 110 through the fourth connecting shaft 112. The second locking block 192 is movably arranged on the second rotating seat 190. The third connecting shaft 351 can cooperate with the second locking block 192 to press the second locking block 192 on the fourth connecting shaft 112 or release the pressure.

[0075] It is understandable that if Figure 3 、 Figure 5 and Figure 6 As shown, the fourth connecting shaft 112 is inserted into the second rotating seat 190, the second locking block 192 is slidably connected to the second rotating seat 190 and can move up and down, the second locking block 192 is located on the lower side of the second connecting hole 191, and the lower end of the third connecting shaft 351 can pass through the second connecting hole 191 and contact the second locking block 192. When it is necessary to restrict the rotation of the second rotating seat 190 relative to the main housing 110, the second knob 350 is tightened, so that the lower portion of the third connecting shaft 351 pushes the second locking block 192 downward and the second locking block 192 is pressed onto the fourth connecting shaft 112, thereby restricting the rotation of the second rotating seat 190 and simultaneously restricting the rotation of the second housing 340 rotating therewith. When it is necessary to release the rotation restriction, the second knob 350 is loosened, so that the third connecting shaft 351 moves upward, thereby releasing the push on the second locking block 192 and the pressure between the second locking block 192 and the fourth connecting shaft 112, so that the second rotating seat 190 can rotate relative to the main housing 110. The above structure is simple. By rotating the second knob 350, the clutch control between the fourth transmission member 180 and the third transmission member 170 is realized, and the locking control between the second rotating seat 190 and the main housing 110 is realized, which is convenient for operation and use.

[0076] In actual application, teeth and grooves can be set between the second locking block 192 and the fourth connecting shaft 112 to achieve a better rotation restriction effect, or an anti-slip structure can be set; in addition to the above structure, the second locking structure can also be a bolt set on the second shell seat 340. By tightening or loosening the bolt, the bolt or the second shell seat 340 is pressed on the main shell 110 or the pressure is released, thereby achieving rotation restriction or releasing the rotation restriction of the second shell seat 340, thereby limiting the rotation of the second rotating seat 190 or releasing the restriction. The specific structure can also be changed accordingly according to actual use needs.

[0077] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
