[0046] It is conceivable that, in some embodiments of the present application, the switching mechanism is a slider rotatably arranged on the first handle 110 or the second handle 120, and the blocking of the protruding structure is achieved by sliding the slider, thus achieving the locking and unlocking functions of the handle assembly and the shearing assembly 200.

[0047] It is conceivable that, in some embodiments of the present application, the switching mechanism can also be a plug-in pin driving mechanism, and the limiting structure is a pin hole, and the locking and unlocking of the handle assembly and the shearing assembly 200 can be achieved by the plug-in cooperation or separation of the plug-in pin and the pin hole.

[0048] As shown in Figure 7 , Figure 8 , in some embodiments of the present application, the first handle 110 is provided with a first connecting portion 111, the second handle 120 is provided with a second connecting portion 121, the first connecting portion 111 and the second connecting portion 121 are connected through a first rotating shaft 130, and a rotating piece 310 is arranged on the first rotating shaft 130 and can rotate around the first rotating shaft 130, that is, the rotating piece 310 is coaxially arranged with the first handle 110 and the second handle 120, thus simplifying the assembly structure.

[0050] As shown in Figure 7 , Figure 8 , Figure 9 , in some embodiments of the present application, the rotating piece 310 is arranged on the first connecting portion 111 and provided with an outwardly protruding driving portion 312, thus facilitating the user to control the rotating piece 310.

[0051] Specifically, as shown in Figure 7 , Figure 8 , Figure 9 , the first handle 110 is provided with two spaced first connecting portions 111, a first accommodating cavity 112 is formed between the two first connecting portions 111, the second handle 120 is provided with two spaced second connecting portions 121, a second accommodating cavity 122 is formed between the two second connecting portions 121, the two second connecting portions 121 can be accommodated in the first accommodating cavity 112, adjacent first connecting portions 111 and second connecting portions 121 are connected through the first rotating shaft 130, the shearing assembly 200 can be inserted into the second accommodating cavity 122, and the rotating piece 310 is arranged on one of the first connecting portions 111, thus meeting the control requirements and facilitating the control.

[0052] As shown in Figure 1As shown in the drawings, in some embodiments of the present application, the first handle 110 is provided with a locking position label, when the driving part 312 is rotated to correspond to the locking position label, the rotating part 310 is in the locking position, and the cutting assembly 200 cannot be pulled out of the handle assembly, when the rotating part 310 is rotated to deviate from the locking position, the cutting assembly 200 will be loose or can be pulled out of the handle assembly.

[0053] Specifically, the locking position label is a "Lock" text mark, of course, in the specific implementation process, the locking position label can also be an "OFF" label, a convex point label, etc., which will not be described in detail here.

[0054] It is conceivable that in some embodiments of the present application, rotating parts 310 can also be provided on both first connecting parts 111, and the upper and lower sides of the cutting assembly 200 are provided with convex structures, which can achieve more stable locking effect.

[0055] As shown in the drawings, Figure 8 , Figure 9 In some embodiments of the present application, the rotating part 310 is arranged on the first connecting part 111, and the first connecting part 111 and the second connecting part 121 are respectively provided with an arc-shaped slot 313 capable of allowing the extension part 311 to pass through, so as to allow the extension part 311 to rotate to the locking or unlocking position.

[0056] Specifically, as shown in the drawings, Figure 7 , Figure 8 , Figure 9 The first handle 110 is provided with two first connecting parts 111 which are spaced apart, and a first accommodating cavity 112 is formed between the two first connecting parts 111, the second handle 120 is provided with two second connecting parts 121 which are spaced apart, and a second accommodating cavity 122 is formed between the two second connecting parts 121, the two second connecting parts 121 can be placed into the first accommodating cavity 112, adjacent first connecting part 111 and second connecting part 121 are connected through the first rotating shaft 130, the cutting assembly 200 can be inserted into the second accommodating cavity 122, the rotating part 310 is arranged on one of the first connecting parts 111, and the extension part 311 passes through the arc-shaped slot 313 and enters the second accommodating cavity 122.

[0057] It is conceivable that in some embodiments of the present application, when the first cutting part 210 and the second cutting part 220 are not opened, the extension part 311 can slide along the arc-shaped slot 313 to the locking position or the unlocking position, so that the cutting assembly 200 and the handle assembly can be normally separated and assembled, when the first cutting part 210 and the second cutting part 220 are unfolded, the arc-shaped slots 313 of the two are relatively slid, the slidable space of the extension part 311 is narrowed, and the extension part 311 is limited in the locking position, that is, when the first cutting part 210 and the second cutting part 220 are unfolded, the cutting assembly 200 and the handle assembly cannot be disassembled, so as to avoid the exposed blade from hurting or bumping damage.

[0058] It can be understood that, in some embodiments of the present application, the arc-shaped slot 313 is arranged to be longer, so that when the first shear member 210 and the second shear member 220 are unfolded, the arc-shaped slots 313 of the two are relatively slid, and the relatively overlapped arc-shaped slots 313 can provide the extension 311 to slide to the locked position or the unlocked position, so that the shear assembly 200 and the handle assembly can be detached regardless of whether the first shear member 210 and the second shear member 220 are folded or unfolded, facilitating replacement of the shear assembly 200.

[0059] As shown in Figure 7 , Figure 8 , Figure 9 , in some embodiments of the present application, the first handle 110 is provided with two first connecting portions 111 which are spaced apart, and a first accommodating cavity 112 is formed between the two first connecting portions 111, the second handle 120 is provided with two second connecting portions 121 which are spaced apart, and a second accommodating cavity 122 is formed between the two second connecting portions 121, the two second connecting portions 121 can be placed into the first accommodating cavity 112, adjacent first connecting portions 111 and second connecting portions 121 are connected through a first rotating shaft 130, and the shear assembly 200 can be inserted into the second accommodating cavity 122, thereby improving the connection structure strength of the first handle 110 and the second handle 120, and facilitating loading of the shear assembly 200.

[0060] Specifically, the second connecting portion 121 is provided with a nut or an internally threaded hole, and the first rotating shaft 130 is screwed with the nut or the internally threaded hole after penetrating through the first connecting portion 111, so as to connect the first connecting portion 111 and the second connecting portion 121.

[0061] As shown in Figure 8 , Figure 9 , in some embodiments of the present application, the second connecting portion 121 is embedded with a nut, so as to cooperate with the first rotating shaft 130.

[0062] As shown in Figure 3 , in some embodiments of the present application, the extension 311 penetrates into the second accommodating cavity 122, so as to cooperate with the protruding structure of the shear assembly 200 in the second accommodating cavity 122.

[0063] As shown in Figure 2 , Figure 4 , Figure 5 , Figure 6 , in some embodiments of the present application, the first shear member 210 and the second shear member 220 are connected through a second rotating shaft 230, and an end cap portion 231 is arranged at an end of the second rotating shaft 230, and the end cap portion 231 forms a protruding structure, which is simple in structure and does not need to additionally configure a protruding structure.

[0064] Specifically, as shown in Figure 6As shown, the second rotating shaft 230 is provided with an internal thread hole and a limiting screw, the first and second shearing members 210 and 220 are respectively provided with shaft holes, and the second rotating shaft 230 is connected with the limiting screw after penetrating through the shaft holes, so as to assemble the first and second shearing members 210 and 220.

[0065] In some embodiments of the present application, the protruding structure is arranged near the rotating center of the first and second shearing members 210 and 220, and the first and second shearing arms 211 and 221 are inserted into the first and second handle cavities, so that the assembled structure of the handle assembly and the shearing assembly 200 is more stable and reliable.

[0066] As shown in the drawings, Figure 4 In some embodiments of the present application, after the first and second shearing arms 211 and 221 are inserted into the first and second handle cavities, the extension part 311 is rotated to the front of the end cap part 231, at this time, the first shearing arm 211 is pressed in the first handle cavity, and the second shearing arm 221 is pressed in the second handle cavity, so as to maintain the compactness of the driving force transmission structure and ensure the normal shearing effect of the scissors.

[0067] In the specific implementation process, the quick detachable fastening structure can also be arranged between the first shearing arm 211 and the first handle 110, and the quick detachable fastening structure can also be arranged between the second shearing arm 221 and the second handle cavity, so as to further improve the stability of the driving force transmission structure.

[0068] It is conceivable that in some embodiments of the present application, the protruding structure can also be directly arranged on the main body of the first or second shearing member 210 or 220, which is not described in detail here.

[0069] In some embodiments of the present application, the first handle 110 and the second handle 120 are connected through the first rotating shaft 130, and the first shearing member 210 and the second shearing member 220 are connected through the second rotating shaft 230, and the first rotating shaft 130 and the second rotating shaft 230 are coaxial, so that the driving structure of the two is more stable, reasonable and reliable.

[0070] Specifically, the first handle 110, the second handle 120, the first shearing member 210 and the second shearing member 220 are coaxially arranged, so that the driving structure of the first handle 110 and the second handle 120 to the first shearing member 210 and the second shearing member 220 is more simple and less likely to displace or deviate, for example, when the handle assembly and the shearing assembly 200 are assembled and sheared, the first shearing arm 211 will not displace in the first handle cavity, and the second shearing arm 221 will not displace in the second handle cavity, so that the transmission structure is more reasonable and stable.

[0071] As shown in the drawings, Figure 9As shown, in some embodiments of the present invention, the first handle 110 is provided with a first connecting portion 111, and the second handle 120 is provided with a second connecting portion 121. The first connecting portion 111 and the second connecting portion 121 are connected by a first rotating shaft 130. The first connecting portion 111 is provided with a limiting protrusion 113, and the second connecting portion 121 is provided with a limiting groove 123 corresponding to the limiting protrusion 113. The limiting protrusion 113 is inserted into the limiting groove 123. Through the cooperation between the limiting groove 123 and the limiting protrusion 113, the relative rotation angle of the first handle 110 and the second handle 120 is limited to avoid damage to the scissors.

[0072] In some embodiments of the present invention, a return spring 240 is provided between the first cutting member 210 and the second cutting member 220. The return spring 240 can return the first cutting member 210 and the second cutting member 220 to the unfolded state, making it convenient for the user to use the scissors.

[0073] like Figure 6 As shown, in some embodiments of the present invention, the reset spring 240 is a torsion spring, and the opposing surfaces of the first shear member 210 and the second shear member 220 are provided with an inner cavity 212 for placing the torsion spring. The torsion spring is installed inside, which simplifies the structure and makes it less likely for the torsion spring to fall off and fail.

[0074] In some embodiments of the present invention, the inner cavity 212 may be disposed in the first shear member 210 and / or the second shear member 220, and the inner cavity 212 may be disposed in the slot corresponding to the torsion arm of the torsion spring, thereby realizing the reset function of the torsion spring.

[0075] like Figures 1 to 6 As shown, in some embodiments of the present invention, the shearing assembly 200 further includes a locking mechanism, which can lock the first shearing member 210 and the second shearing member 220 in an unopened position to protect the first shearing member 210 and the second shearing member 220 or prevent the first shearing member 210 and the second shearing member 220 from injuring people.

[0076] In some embodiments of the present invention, a locking mechanism is provided on the shearing assembly 200, which can lock the shearing assembly 200 even after it is disengaged from the handle assembly, making it convenient to store, improving security, and reducing the required storage space.

[0077] It is conceivable that, in some embodiments of the present invention, the locking mechanism may also be provided with the handle assembly, and a corresponding locking engagement structure may be provided with the shearing assembly 200, which may also satisfy the locking requirements.

[0078] like Figure 5 , Figure 6As shown in the figure, in some embodiments of the present application, the locking mechanism comprises a locking piece 250 movably arranged on the first cutting piece 210, the locking piece 250 is provided with a locking portion 251, the second cutting piece 220 is provided with a pushing portion 222 corresponding to the locking portion 251, when the first cutting piece 210 and the second cutting piece 220 are not opened, the locking piece 250 can be moved to make the locking portion 251 abut against the pushing portion 222, so as to limit the opening of the first cutting piece 210 and the second cutting piece 220 relative to each other.

[0079] Of course, in the specific implementation process, the locking mechanism can also be a latch locking mechanism, such as arranging a movable latch on the first cutting piece 210, and arranging a latch hole on the second cutting piece 220, and through the cooperation of the movable latch and the latch hole, the first cutting piece 210 and the second cutting piece 220 can also be locked.

[0080] As shown in the figure, Figure 6 In some embodiments of the present application, the locking piece 250 is connected to the first cutting piece 210 through a shaft peg 252, a compression spring 254 is arranged between the locking piece 250 and a screw cap 253 of the shaft peg 252, so that the locking piece 250 is elastically abutted, the locking piece 250 has a certain elastic movement space, so as to avoid being stuck when abutting against the pushing portion 222.

[0081] In some embodiments of the present application, a reset spring 240 is arranged between the first cutting piece 210 and the second cutting piece 220, when the locking portion 251 of the locking piece 250 abuts against the pushing portion 222, the locking portion 251 is subjected to the elastic reset force of the reset spring 240 and is reversely pushed, so that the locking piece 250 is more likely to be stuck or the rotating shaft is more likely to be stuck, at this time, by slightly moving the locking piece 250, the stuck or stuck condition can be eliminated, so that the locking piece 250 can work normally.

[0082] As shown in the figure, Figures 1 to 4 In some embodiments of the present application, the locking piece 250 is provided with a push handle portion 255, when the cutting assembly 200 is inserted into the handle assembly, the push handle portion 255 is exposed outside the handle assembly, so as to facilitate the user to operate.
