Description

Technical Field

[0001] This utility model relates to the field of cutting tools, and in particular to a pair of scissors. Background Technology

[0002] The existing scissors usually have two handles directly connected to two blades, which cannot be folded and stored, making them less convenient to carry. Some folding scissors can be folded, but they cannot achieve stable locking after folding or effective locking after unfolding, which poses a safety hazard.

[0003] Therefore, there is an urgent need to propose a new scissor structure that can provide better folding and locking effects. Utility Model Content

[0004] The purpose of this invention is to provide a pair of scissors that can improve the folding and locking effects of the scissors.

[0032] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] like Figures 1 to 6 As shown, a pair of scissors includes: a handle assembly 1, a blade assembly 2, and a locking assembly 4. The handle assembly 1 includes a first handle 11 and a second handle 12. The first handle 11 includes a first connecting handle 111 and a first grip portion 112 rotatably connected. The second handle 12 includes a second connecting handle 121 and a second grip portion 122 rotatably connected. The blade assembly 2 includes a first blade 22 and a second blade 21 rotatably connected about a blade rotation axis 23. The first blade 22 is fixedly connected to or integrally formed with the first connecting handle 111, and the second blade 21 is fixedly connected to or integrally formed with the second connecting handle 121. The locking assembly 4 is movably disposed on the second grip portion 122. The second connecting handle 121 is provided with a first locking point 124, and the first grip portion 112 is provided with a second locking point 113. The locking assembly 4 can engage with the first locking point 124 to make the second connecting handle 121 and the second grip portion 122 in an unfolded and locked state, and the locking assembly 4 can engage with the second locking point 113 to make the blade assembly 2 and the handle assembly 1 in a folded and locked state.

[0036] It is understandable that the first handle 11 and the second handle 12 of the handle assembly 1 serve as two gripping structures for a person to hold the scissors. In other words, the first handle 11 and the second handle 12 are the operating structures of the scissors. The first handle 11 includes a first connecting handle 111 and a first gripping part 112, while the second handle 12 includes a second connecting handle 121 and a second gripping part 122, so that both the first handle 11 and the second handle 12 are composed of two parts. The first connecting handle 111 and the first gripping part 112 are rotatably connected, and the second connecting handle 121 and the second gripping part 122 are rotatably connected, so that the first connecting handle 111 and the first gripping part 112 of the first handle 11 can be rotated and folded for storage, and the second connecting handle 121 and the second gripping part 122 of the second handle 12 can be rotated and stored. Simultaneously, the second locking point 113 and the first locking point 124 allow the locking component 4, located on the second grip 122, to selectively engage with one of them. When folding and locking are required, the locking component 4 engages with the second locking point 113 to fold and lock the blade assembly 2, the second handle 12, and the first handle 11, preventing the first handle 11, the second handle 12, and the blade assembly 2 from disengaging. Similarly, the locking component 4 engages with the first locking point 124 to unfold and lock the second connecting handle 121 and the second grip 122, allowing the second handle 12 to be gripped normally. This enables forceful cutting without the second connecting handle 121 and the second grip 122 becoming too close together to cut.

[0037] It should be noted that the first connecting handle 111 and the first gripping part 112 are also rotatably connected to each other, and a locking structure can also be provided between them. For example, a locking structure can be provided on the first connecting handle 111 or the first gripping part 112, and a locking point corresponding to the locking structure can be provided on the first gripping part 112 or the first connecting handle 111. The two can be locked when the first connecting handle 111 or the first gripping part 112 is relatively unfolded, so that the first handle 11 can be gripped normally, and thus force can be applied for cutting without the first gripping part 112 or the first connecting handle 111 being close to each other and unable to cut. Or other locking structures, as long as they can achieve mutual locking of the first connecting handle 111 and the first gripping part 112, are acceptable. This is existing technology, and this embodiment will not be limited in detail here. Furthermore, the connection between the first scissor blade 22 and the first connecting handle 111, and the connection between the second scissor blade 21 and the second connecting handle 121, can be integrally formed, or other fixed connection methods such as welding or hinge. In this embodiment, the integrally formed connection method is preferred. The integrally formed connection method ensures the connection effect between the first scissor blade 22 and the first connecting handle 111, and the connection effect between the second scissor blade 21 and the second connecting handle 121. At the same time, the locking component 4 can be rotatably set on the second gripping part 122, that is, the locking component 4 can rotate to selectively engage with the second locking point 113 or the first locking point 124, or it can be slidably set on the second gripping part 122. It is sufficient to enable the locking component 4 to selectively engage with the second locking point 113 or the first locking point 124.

[0038] Alternatively, in this embodiment, such as Figures 1 to 3 As shown, the locking component 4 is rotatably disposed on the second grip portion 122. The locking component 4 includes a locking protrusion 41, a locking block shaft 42, and a locking block 43. The locking component 4 is rotatably disposed on the second grip portion 122 via the locking block shaft 42. The locking component 4 rotates around the locking block shaft 42. The locking component 4 has a locking protrusion 41 and a locking block 43 respectively at both ends. The locking protrusion 41 can engage with the first locking point 124 to make the second connecting handle 121 and the second grip portion 122 in an unfolded and locked state. At the same time, the locking protrusion 41 can engage with the second locking point 113 to make the scissor blade assembly 2, the second handle 12, and the first connecting handle 111 in a folded and locked state.

[0039] Alternatively, in this embodiment, such as Figures 1 to 3As shown, the second grip 122 can rotate relative to the second connecting handle 121 around the second handle rotation axis 123. At the same time, the first grip 112 is provided with a first rotation axis 13 and a second rotation axis 14 at both ends. In this embodiment, the first connecting handle 111 and the first grip 112 are rotatably connected through the first rotation axis 13. The arrangement of the first rotation axis 13 and the second handle rotation axis 123 allows the second connecting handle 121 and the second grip 122 to rotate relative to each other, as well as the first connecting handle 111 and the first grip 112 to rotate relative to each other.

[0040] It should be noted that, with reference to the appendix of this utility model Figure 1 , Figure 2 For example, when the scissors need to be folded and stored, the locking component 4 (i.e., the locking protrusion 41) disengages from the first locking point 124, releasing the unfolded and locked state of the second connecting handle 121 and the second grip 122. Then, the second grip 122 rotates counterclockwise relative to the second connecting handle 121 around the second handle rotation axis 123, causing the second grip 122 to fold closer to the second connecting handle 121. Further, after folding, the second grip 122 and the second connecting handle 121, together with the first scissor blade 22, the second scissor blade 21, the scissor blade rotation axis 23, and the first connecting handle 111, together form a part, and continue to rotate counterclockwise relative to the first grip 112. When folding is complete, the locking component 4 is engaged with the second locking point 113, so that the scissors are in a folded and locked state. Conversely, when a person needs to use the scissors, the locking component 4 (i.e., the locking protrusion 41) disengages from the second locking point 124. At point 113, the folded second grip 122 and second connecting handle 121, together with the first scissor blade 22, the second scissor blade 21, the scissor blade rotation axis 23, and the first connecting handle 111, are rotated clockwise relative to the first grip 112 to unfold. Then, the second grip 122 is rotated clockwise relative to the second connecting handle 121 to unfold separately. After fully unfolding, the locking component 4 is engaged at the first locking point 124, so that the second grip 122 will not rotate counterclockwise relative to the second connecting handle 121. This ensures that the scissors are in an unfolded and locked state, guaranteeing normal cutting. When the scissors are used in casualty rescue, animal protection rescue, fire rescue, or even underwater use, personnel can not only stably and safely store the folded scissors, but also effectively lock them when unfolded, improving the effectiveness of the scissors in different application scenarios.

[0041] Optionally, in this embodiment, a first elastic element (not shown in the figure) may be provided at the second handle rotation shaft 123. The first elastic element ensures that the second connecting handle 121 and the second gripping part 122 always have an unfolding motion tendency. The locking component 4 (i.e., the locking protrusion 41) engages with the second locking point 113 to cause the first elastic element to undergo elastic deformation. The locking component 4 (i.e., the locking protrusion 41) disengages from the second locking point 113, and the first elastic element drives the second connecting handle 121 and the second gripping part 122 to unfold.

[0042] In some embodiments, the second handle rotation shaft 123 is a rotation shaft with elastic function. A first elastic element is provided in the second handle rotation shaft 123. For example, when the elastic element is folded and stored, because the second grip portion 122 rotates counterclockwise relative to the second connecting handle 121 around the second handle rotation shaft 123, and the first elastic element has elastic force, it can continuously perform elastic compression when the second grip portion 122 rotates counterclockwise, that is, perform elastic energy storage. Finally, the folded second grip portion 122 and the second connecting handle 121, together with the first scissor blade 22, the second scissor blade 21, the scissor blade rotation shaft 23 and the first connecting handle 111, together form a part relative to the second connecting handle 121. The first grip 112 continues to rotate and fold counterclockwise, and is engaged with the locking component 4 at the second locking point 113, so that the scissors are in a folded and locked state. It should be noted that when the scissors are in the folded and locked state, the first elastic element is always compressed. When the person needs to unfold the scissors, the locking component 4 (i.e., the locking protrusion 41) needs to be disengaged from the second locking point 113. At this time, the compressed first elastic element and the second handle rotation shaft 123 are unlocked and can release elastic potential energy, thereby allowing the second grip 122 to be quickly unfolded relative to the second connecting handle 121, which realizes the quick unfolding function of the second handle 12.

[0043] It should be noted that the first elastic element inside the second handle rotation shaft 123 applies force in different directions to different objects. That is, the elastic force on the second grip 122 is opposite to the elastic force on the second connecting handle 121. Taking the above-mentioned operating mode as an example, the first elastic element inside the second handle rotation shaft 123 can only provide a clockwise elastic force. When the second grip 122 is folded counterclockwise around the second handle rotation shaft 123 relative to the second connecting handle 121, the first elastic element can store elastic energy because the folding direction is opposite to the elastic force direction of the first elastic element. Thus, when the locking component 4 (i.e., the locking protrusion 41) exits the second locking point 113, the second handle 12 can be quickly unfolded. This setting ensures that the scissors can be quickly unfolded, so that the scissors can be stably, reliably and quickly unfolded when used in casualty rescue, animal protection rescue, fire rescue, or even underwater use.

[0044] It should be noted that the specific type of the first elastic element inside the second handle rotating shaft 123 can be an elastic band structure, a spring structure, an airbag structure, a torsion spring structure, etc., all of which are existing technologies and will not be described in detail here.

[0045] In other embodiments, the first rotating shaft 13 also adopts the above-mentioned first elastic element. Similarly, if the first rotating shaft 13 is equipped with the first elastic element, it can provide a clockwise elastic force. When the second grip 122 and the second connecting handle 121, together with the first scissor blade 22, the second scissor blade 21, the scissor blade rotating shaft 23 and the first connecting handle 111, are folded as a part relative to the first grip 112 in a counterclockwise direction, the first elastic element can store elastic energy because the folding direction is opposite to the elastic force direction of the first elastic element. Thus, when the locking component 4 (i.e. the locking protrusion 41) exits the second locking point 113, the first handle 11 can be quickly unfolded. This setting ensures that the scissors can be quickly unfolded, so that when the scissors are used in casualty rescue, animal protection rescue, fire rescue and even underwater use, the scissors can be unfolded stably, reliably and quickly, and cooperate with the first elastic element in the second handle rotating shaft 123 to realize the quick and complete unfolding of the entire scissors.

[0046] Alternatively, in this embodiment, such as Figures 1 to 5 As shown, the first gripping part 112 is provided with a receiving space with an opening, and the scissor blade assembly 2 can pass through the opening and be received in the receiving space when the scissors are folded and locked.

[0047] It is understandable that the first grip 112 has an internal accommodating space with an opening. When the scissors are folded and locked, the blade assembly 2 can pass through the opening and be accommodated in the accommodating space. This further ensures that the blade assembly 2 can be completely accommodated in the accommodating space without being exposed to the outside when folded and locked, reducing the space occupied by the scissors after folding and storage, making the structure compact, and preventing the folded scissors from scratching people, thus improving the usability of the scissors.

[0048] Alternatively, in this embodiment, such as Figure 2As shown, the first gripping part 112 has a first plate 1121 and a second plate 1122 arranged in parallel intervals. The area between the first plate 1121 and the second plate 1122 constitutes an accommodating space. The accommodating space has openings on both sides of the scissors' unfolding and folding direction, so that the scissor blade assembly 2 can pass through the openings on both sides of the scissors' unfolding and folding direction and be accommodated in the accommodating space when the scissors are folded and locked. The internal structure can be observed and inspected through the openings on both sides of the scissors' unfolding and folding direction. At the same time, the arrangement of the first plate 1121 and the second plate 1122 in parallel intervals to form the accommodating space further reduces the complexity of the internal structure of the scissors and improves the ease of disassembly. The first plate 1121 and the second plate 1122 can provide effective protection for the scissor blade assembly 2 inside after folding.

[0049] Alternatively, in this embodiment, such as Figures 1 to 5 As shown, the first grip portion 112 has a straight arm structure, and the second grip portion 122 includes a thumb ring 1221 and a grip arm 1222 connected to each other. The grip arm 1222 is rotatably connected to the second connecting handle 121.

[0050] It is understandable that the first grip 112 is a straight-arm grip structure, while the second grip 122 is a ring grip structure composed of a thumb ring 1221 and a grip arm 1222. This allows the user to use a combination of a thumb ring grip and a straight-arm four-finger grip, thereby applying greater force during the cutting operation. Existing technologies generally use a two-hand ring grip or a two-hand grip arm grip. While a two-hand ring grip can improve the flexibility of scissors cutting, it makes it impossible for the user to apply greater cutting force. While a two-hand grip arm grip can apply greater cutting force, it cannot provide a more flexible cutting effect. This embodiment uses both a ring grip and a grip arm grip, which not only ensures high cutting flexibility but also allows for the application of greater force during the cutting operation by using a thumb ring plus a straight arm and a four-finger lever arm.

[0051] Alternatively, in this embodiment, such as Figure 1 , Figure 3 As shown, the scissors also include an extension component 3. An extension component interface 31 is provided on the first handle 11 and / or the second handle 12. The extension component 3 can be detachably installed on the extension component interface 31.

[0052] It is understood that the first handle 11 and / or the second handle 12 are provided with an expansion component interface 31, thereby allowing the expansion component 3 to be detachably installed on the expansion component interface 31. The expansion component 3 can be a lighting device, a laser detection device, a communication device, etc., and is not specifically limited in this embodiment. This is because the existing scissors have a relatively simple function, and their effectiveness is limited when facing situations such as casualty rescue, animal protection rescue, fire rescue, or even underwater use. In this embodiment, for example, the lighting device is provided on the first handle 11 and / or the second handle 12 through the expansion component interface 31, so that the scissors can also provide lighting while performing the conventional cutting function. For example, in casualty rescue, animal protection rescue, and fire rescue, when the operating area is small and the light is limited, this is particularly useful. In environments with poor lighting, the scissors can be illuminated directly by their lighting device (i.e., extension component 3) without the need for a separate lighting component. They can also provide effective lighting in complex environments such as underwater, enhancing the scissors' functional integration and usability. Alternatively, a laser detection device can be installed on the first handle 11 and / or the second handle 12 via the extension component interface 31, enabling the scissors to perform laser ranging and laser detection functions in addition to their conventional cutting function, further enhancing their functional integration. Conversely, a communication device can be installed on the first handle 11 and / or the second handle 12 via the extension component interface 31, allowing the scissors to perform communication functions in addition to their conventional cutting function, further enhancing their functional integration.

[0053] Alternatively, in this embodiment, such as Figure 1 , Figure 2 , Figure 3 As shown, the expansion component interface 31 is disposed on the second grip 122. When one end of the locking component 4 is engaged with the first locking point 124 to complete the unfolding and locking of the second handle 12, the other end of the locking component 4 can abut against the expansion component 3 on the expansion component interface 31.

[0054] It is understood that in this embodiment, the extension component 3 is connected to the second handle 12 via the extension component interface 31, and more specifically, it is disposed on the grip arm 1222 of the second handle 12. This arrangement ensures that when one end of the locking component 4 (i.e., the locking protrusion 41) engages with the first locking point 124 to complete the unfolding and locking of the second handle 12, the other end of the locking component 4 (i.e., the locking block 43) can abut against the extension component 3 on the extension component interface 31. This arrangement ensures that when the second connecting handle 121 and the second grip 122 are in the unfolded and locked state, the first locking point 124 at one end is locked, and the extension component 3 on the extension component interface 31 at the other end is also effectively abutted. The expansion component 3 is tightly secured and can cooperate with the first locking point 124 to abut against each other, improving the stability of the unfolded and locked state as well as the installation stability of the expansion component 3. Therefore, in complex or even underwater environments, the expansion component 3 will not be at risk of falling off. Most importantly, both ends of the locking component 4 achieve the unfolded and locked state of the second connecting handle 121 and the second grip 122, as well as the installation and locking of the expansion component 3. The two are locked simultaneously. When it is necessary to remove the expansion component 3, the locking component 4 (i.e., the locking protrusion 41) must first be removed from the first locking point 124, further ensuring the disassembly and assembly effect of the expansion component 3.

[0055] Alternatively, in this embodiment, such as Figures 4 to 7 As shown, at least one end of the first gripping part 112 is rotatably provided with a tool 6.

[0056] It is understood that in this embodiment, in addition to the conventional cutting by the scissor blade assembly 2, a tool 6 is also provided. The tool 6 can be a hook knife, saw knife, cutting knife, window breaker, etc. In the prior art, scissors usually only have conventional scissor blades and do not have other types of knife structures. However, in this embodiment, the tool 6 is rotatably arranged on the first rotating shaft 13 and / or the second rotating shaft 14, which significantly improves the functional integration of the scissors. It not only has conventional cutting function, but also other functions such as sawing and hooking. Furthermore, because the tool 6 is rotatably arranged on the first rotating shaft 13 and / or the second rotating shaft 14, the tool 6 can also be folded.

[0057] Optionally, in this embodiment, the tool 6 can be folded and stored in the accommodating space inside the first gripping part 112. The tool 6 is unfolded when in use, and when finished, it can be rotated through the opening and stored in the accommodating space. This further ensures that the tool 6 can be completely contained in the accommodating space in the folded and locked state without being exposed to the outside, thus improving the space occupied by the tool 6 after folding and storing, and preventing the folded tool 6 from scratching people, thereby improving the effectiveness of the scissors.

[0058] Optionally, the tool 6 can be folded and stored in the accommodating space between the first plate 1121 and the second plate 1122. The tool 6 can be unfolded when in use, and when not in use, the tool 6 can be rotated and stored in the accommodating space between the first plate 1121 and the second plate 1122, which can provide effective protection for the folded tool 6.

[0059] Alternatively, in this embodiment, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the first gripping part 112 is provided with a receiving space, in which the tool 6 can be accommodated. The tool 6 is provided with an elastic boss 61. The elastic boss 61 can be compressed by the inner wall of the receiving space to make the tool 6 folded. The elastic boss 61 can abut against the outer periphery of the end of the first gripping part 112 to make the tool 6 unfolded.

[0060] Understandably, the tool 6 is provided with a separate elastic boss 61 that can spring up relative to the tool 6. Because the tool 6 is rotatably mounted on the first rotation axis 13 and / or the second rotation axis 14, when the tool 6 does not need to be unfolded, the elastic boss 61 is compressed by the inner wall of the accommodating space of the first gripping part 112, keeping the tool 6 in a folded state. When the tool 6 needs to be unfolded for use, the tool 6 is rotated in the unfolding direction, causing the elastic boss 61 to disengage from the inner wall of the accommodating space of the first gripping part 112. At the same time, when fully unfolded, the elastic boss 61 abuts against... The elastic protrusion 61 cannot rotate because it is connected to the outer periphery of the first gripping part 112, thus ensuring that the tool 6 cannot retract, so that the tool 6 is in an unfolded and locked state. When it is time to store it after use, simply press the elastic protrusion 61 to release it from the tightness of the outer periphery of the first gripping part 112, and then the tool 6 can be folded in the following direction (the folding direction is opposite to the unfolding direction). This causes the elastic protrusion 61 to be compressed by the inner wall of the accommodating space of the first gripping part 112, thus folding the tool 6.

[0061] like Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, it can be understood that when tool 6 needs to be unfolded for use, tool 6 is rotated in the unfolding direction to disengage the elastic protrusion 61 from the inner wall of the accommodating space of the first gripping part 112, and tool 6 is fully unfolded through the opening. At the same time, when fully unfolded, the elastic protrusion 61 abuts against and locks the outer periphery of the end of the first gripping part 112 (i.e., the outer edge of the accommodating space) so that the elastic protrusion 61 cannot rotate back, thereby ensuring that tool 6 cannot retract, so that tool 6 is in an unfolded and locked state. When it is time to store it after use, simply press the elastic protrusion 61 to disengage it from the abutting and locking of the outer periphery of the end of the first gripping part 112 (i.e., the outer edge of the accommodating space), and then the tool 6 can be folded in the folding direction (opposite to the unfolding direction) to rotate back, so that the elastic protrusion 61 is compressed by the inner wall of the accommodating space of the first gripping part 112 and enters the accommodating space through the opening, so that it is in a folded and stored state, thus completing the folding and storage of tool 6. It can provide effective protection for the internal tools 6 when folded, reducing the actual space required for scissors and preventing people from being cut.

[0062] It should be noted that the specific type of elastic structure of the elastic boss 61 is existing technology and is not further limited in this embodiment. For example, it can be a spring structure boss, an air cushion structure boss, etc. In this embodiment, the end of the tool 6 near the first rotating shaft 13 and / or the second rotating shaft 14 is connected to the elastic boss 61. The elastic boss 61 includes a boss and a spring. There is a gap between the elastic boss 61 and the tool 6. The spring is sandwiched between the tool 6 and the boss. The elastic boss 61 can be closer to or farther away from the tool 6. The end of the elastic boss 61 facing the tool 6 is provided with a receiving cavity. For example, when the elastic boss 61 is a spring structure boss, the spring is received in the receiving cavity of the end of the elastic boss 61 facing the tool 6. When the elastic boss 61 is compressed, the spring in the receiving cavity will be compressed by the elastic boss 61 to store elastic energy. Of course, in other embodiments, the elastic boss 61 and the tool 6 can also be elastically matched in other ways.

[0063] More specifically, such as Figure 6 , Figure 7Taking the example shown, when the elastic boss 61 is a spring structure boss, the elastic boss 61 is compressed in the accommodating space of the second gripping part 122 in the folded state. At this time, the spring structure in the accommodating cavity of the elastic boss 61 is elastically compressed to store elastic energy. When the tool 6 needs to be unfolded for use, the tool 6 needs to be rotated in the unfolding direction. When the tool 6 is completely disengaged from the edge of the second gripping part 122 (i.e., the edge of the accommodating space), the spring in the accommodating cavity releases its elastic potential energy. At this time, the elastic boss 61 is completely released from the compressed state, allowing the tool 6 to quickly spring open. The elastic boss 61, which has already been opened, locks the edge of the second gripping part 122 (i.e., the edge of the accommodating space). This prevents the elastic boss 61 from rotating, thus ensuring that the tool 6 cannot retract, keeping it in an unfolded and locked state. Conversely, when storage is required after use, simply press the elastic boss 61 to compress the spring in the receiving cavity until the elastic boss 61 is fully compressed and locked away from the edge of the second grip 122 (i.e., the edge of the receiving space). Then, the tool 6 can be folded in the opposite direction to the unfolding direction, causing the elastic boss 61 and the spring in the internal receiving cavity to be compressed by the edge of the second grip 122 and enter the receiving space through the opening, thus folding and storing the tool 6. This provides effective protection for the folded tool 6, reduces the usable space of the scissors, and prevents injury to personnel.

[0064] In other embodiments, when the elastic boss 61 is an air cushion structure boss, the elastic boss 61 includes a boss and an air cushion. There is a gap between the elastic boss 61 and the tool 6. The air cushion is sandwiched between the tool 6 and the boss. The air cushion can be compressed to store elastic energy. This is not limited in detail here.

[0065] Alternatively, in this embodiment, such as Figure 4 As shown, tool 6 includes a saw blade, which is rotatably mounted on the second rotating shaft 14. It can be understood that, for example... Figures 1 to 4 As shown, when the first connecting handle 111 and the first grip 112 are rotatably connected via the first rotating shaft 13, the saw blade is rotatably mounted on the second rotating shaft 14. It can be understood that since the saw blade usually needs to cut along the cutting section, and the application scenario of the saw blade is usually a hard material with a long cutting length, and it needs more stable support force than hook blades and cutting blades, in this embodiment the shear blade assembly 2 and the saw blade are rotatably mounted on different rotating shafts to avoid interference with the shear blade assembly 2. Even when the shear blade assembly 2 is in the unfolded state, the saw blade can still be used normally.

[0066] Alternatively, in this embodiment, such as Figure 1 , Figure 3 , Figure 5 , Figure 8 As shown, the scissors also include a wire cutter 5, which includes a fixed cutting blade 51, a movable cutting blade 52, and a pressing member 53. The fixed cutting blade 51 is disposed at one end edge of the first gripping part 112, the movable cutting blade 52 is slidably disposed along the length direction of the first gripping part 112, and the pressing member 53 is connected to the first gripping part 112. The pressing member 53 can drive the movable cutting blade 52 to approach or move away from the fixed cutting blade 51.

[0067] It is understood that the fixed scissor blade 51 is disposed at one end edge of the first gripping part 112, while the movable scissor blade 52 is slidably disposed along the length direction of the first gripping part 112. In this embodiment, the pressing member 53 is rotatably connected to the first gripping part 112, so that the pressing member 53 can rotate and drive the movable scissor blade 52 to approach or move away from the fixed scissor blade 51. In other embodiments, the pressing member 53 may also slide, thereby driving the movable scissor blade 52 to approach or move away from the fixed scissor blade 51. When the wire cutter approaches the fixed shear blade 51, it can cut the object to be cut between the fixed shear blade 51 and the movable shear blade 52, thus realizing the wire cutting action of the wire cutter 5. At the same time, the pressing member 53 is rotatably connected to the first grip part 112, so that the person can achieve the wire cutting action simply by pressing the pressing member 53. This makes the scissors not only have conventional cutting functions, but also have strong wire cutting capabilities. For example, when applied to casualty rescue, animal protection rescue, fire rescue, or even underwater use, the wire cutter 5 can cut screws, wires, cables, etc. in a timely and efficient manner, which improves the functionality and effectiveness of the scissors.

[0068] It should be noted that the shearing surfaces of the fixed shearing blade 51 and the movable shearing blade 52 face each other, allowing the movable shearing blade 52 to perform a wire-cutting operation when it is close to the fixed shearing blade 51. In this embodiment, the fixed shearing blade 51 is located at the edge of the first gripping part 112 away from the first rotating axis 13. The location of the fixed shearing blade 51 at the edge of the first gripping part 112 away from the first rotating axis 13 ensures that the wire-cutting shear 5 will not interfere with the shearing blade assembly 2 when cutting the wire. At the same time, the normal operation of the wire-cutting shear 5 will not be affected whether the shearing blade assembly 2 is folded or unfolded.

[0069] Alternatively, in this embodiment, such as Figure 8 As shown, the pressing member 53 includes a pressing arm 531, a pressing member rotating shaft 532, and a roller 533 connected to one end of the pressing arm 531. The pressing arm 531 can rotate around the pressing member rotating shaft 532, so that the roller 533 can be driven by the pressing arm 531 and push the moving shear blade 52 close to the fixed shear blade 51 to cut the wire. A second elastic member is provided between the fixed shear blade 51 and the moving shear blade 52. The second elastic member is configured to make the fixed shear blade 51 and the moving shear blade 52 always tend to move away from each other.

[0070] Understandably, roller 533 is located at one end of pressing arm 531. The function of roller 533 is to roll and connect with the moving shear blade to reduce friction. Since pressing arm 531 can rotate around pressing member pivot 532, for example... Figure 8 As shown, when a wire cutting operation is required, the operator presses down on one end of the pressing arm 531 and rotates it around the pressing component shaft 532. At this time, the roller 533 at one end is driven, and then the roller 533, which is connected to the roller, pushes the moving scissor blade 52 closer to the fixed scissor blade 51 to cut the wire. At this time, it should be noted that the second elastic element (not shown in the figure) between the fixed scissor blade 51 and the moving scissor blade 52 is compressed, that is, the second elastic element stores elastic energy. When the wire cutting is completed, the second elastic element between the fixed scissor blade 51 and the moving scissor blade 52 is released elastically, pushing the moving scissor blade 52 away from the fixed scissor blade 51, ensuring the convenience of the wire cutting operation. In this embodiment, the pressing component shaft 532 is set in the middle area of ​​the pressing component 53, and the pressing component shaft 532 is set between the first rotating shaft 13 and the second rotating shaft 14. The roller 533 is connected to the end away from the pressing area of ​​the pressing arm 531.

[0071] Alternatively, in this embodiment, such as Figure 8 As shown, the fixed shear blade 51 has an elastic element mounting hole 511 at one end facing the movable shear blade 52, and the second elastic element is installed in the elastic element mounting hole 511.

[0072] It should be noted that the specific type of the second elastic element is existing technology and is not further limited in this embodiment. For example, it can be a spring structure, an elastic rubber structure, etc.

[0073] Alternatively, in this embodiment, such as Figure 8 As shown, the movable shear blade 52 has a clearance groove 521, and the second rotating shaft 14 passes through the clearance groove 521.

[0074] Understandably, the movable shear blade 52 has a relief groove 521 and the second rotating shaft 14 passes through the relief groove 521, so that the movable shear blade 52 is guided by the second rotating shaft 14 through the relief groove 521, so that it can only slide along the length direction of the first grip part 112. The relief groove 521 ensures that the movable shear blade 52 will not detach from the scissors, and at the same time ensures the stability of the wire cutter 5 in use.

[0075] Alternatively, in this embodiment, such as Figure 1 , Figure 3 , Figure 8 As shown, a locking knob 534 is rotatably provided on the pressing area surface of the pressing arm 531, and the first gripping part 112 is provided with a groove (not shown in the figure) that engages with the locking knob 534.

[0076] Understandably, when a wire disconnection operation is not required, the pressing member 53 can be accommodated in the receiving space of the first gripping part 112. When the pressing member 53 is accommodated in the receiving space, the pressing area surface of the pressing arm 531 is flush with the opening of the first gripping part 112 or the pressing area surface of the pressing arm 531 is lower than the opening of the first gripping part 112. At this time, the first gripping part 112 is provided with a groove that engages with the locking knob 534, so that the locking knob 534 can be engaged in the groove after rotation, thereby ensuring that the pressing member 53 (more specifically the pressing arm 531) does not protrude out of the receiving space and is locked at the same time, ensuring the normal operation of other structures without interference.

[0077] It should be noted that because the locking knob 534 is locked in the groove of the first grip 112 after being rotated, the moving blade 52 and the fixed blade 51 are in contact at this time. Therefore, when the locking knob 534 is rotated and locked, there is no gap between the moving blade 52 and the fixed blade 51. This avoids cutting people when the wire cutter 5 is folded, stored and locked in actual use, thus improving the safety of using the wire cutter 5 and the scissors.

[0078] Alternatively, in this embodiment, such as Figure 3 As shown, the handle assembly 1 also includes an anti-slip handle 15, with its two ends connected to the first rotating shaft 13 and the second rotating shaft 14, respectively.

[0079] Understandably, the anti-slip handle 15 ensures that the scissors will not easily slip from the hand when cutting. More importantly, the anti-slip handle 15 allows the operator to use one hand to perform the cutting operation with the first handle 11 and the second handle 12, while also gripping the anti-slip handle 15 with the other hand, thereby improving cutting stability and allowing for the application of greater cutting force.

[0080] Alternatively, in this embodiment, such as Figure 3 As shown, the anti-slip handle 15 is detachably connected to the first rotating shaft 13 and the second rotating shaft 14 at both ends, and the anti-slip handle 15 has a ring-shaped structure.

[0081] It is understandable that the anti-slip handle 15 is detachably connected to the first rotating shaft 13 and the second rotating shaft 14 at both ends, so that the anti-slip handle 15 can be installed or removed according to actual needs. At the same time, the anti-slip handle 15 has a ring-shaped structure, which can improve the grip of the other hand.

[0082] Alternatively, in this embodiment, such as Figure 3As shown, the scissors also include an adjusting wrench 16, which is suspended on the anti-slip handle 15. The adjusting wrench 16 is used to adjust the mounting bolts, shafts, etc. of the scissors, or to adjust the mounting bolts, shafts, etc. of other workpieces besides the scissors. The adjusting wrench 16 can be suspended on the anti-slip handle 15 to prevent the adjusting wrench 16 from being lost. Meanwhile, because the anti-detachment handle 15 has a ring-shaped structure, the adjusting wrench 16 can move adaptively along the ring-shaped anti-detachment handle 15, thereby selectively removing or tightening the mounting bolts and shafts on other workpieces besides the scissors. Furthermore, because the two ends of the anti-detachment handle 15 are detachably connected to the first rotating shaft 13 and the second rotating shaft 14 respectively, when it is necessary to disassemble the adjusting wrench 16 separately to remove or tighten the mounting bolts and shafts on the scissors body or on other workpieces besides the scissors, only the end of the anti-detachment handle 15 connected to the first rotating shaft 13 or the end connected to the second rotating shaft 14 can be disassembled. Regardless of which end is disassembled, the adjusting wrench 16 can be removed, thereby removing or tightening the mounting bolts and shafts on the scissors body or on other workpieces besides the scissors. This further enhances the functional versatility and functional integration of the scissors.

[0083] Alternatively, in this embodiment, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the surface of the first grip portion 112 is provided with anti-slip texture 1123.

[0084] Understandably, the surface of the first gripping part 112 is provided with anti-slip texture 1123, which can ensure that when the person holds the scissors, the gripping effect of the first gripping part 112 is improved, and the occurrence of slippage or other situations when the person holds the scissors is prevented, thereby improving the stability of the cutting operation.

[0085] It should be noted that in other embodiments, anti-slip textures can be provided in areas such as the grip arm 1222, the second connecting handle 121, and the pressing arm 531, which further improves grip stability and shearing effect.

[0086] Alternatively, in this embodiment, such as Figure 1 As shown, the surfaces of the first shear blade 22 and / or the second shear blade 21 are provided with measuring scales 211.

[0087] It is understandable that the first scissor blade 22 and / or the second scissor blade 21 are provided with measuring scales 211, so that the scissors also have a certain distance measuring function when facing specific application scenarios, which further enhances the versatility and integration of the scissors.

[0088] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
