Description
Technical Field
[0001] The utility model relates to the field of stationery and file parts, in particular to a pair of multifunctional scissors. Background Art
[0002] Scissors, as a traditional tool, have long been integrated into people's daily lives. They are used for a wide range of purposes, including but not limited to cutting paper, cloth, rope, and other sheet or linear objects. The structural characteristic of scissors lies in their dual-edged structure, which achieves shearing through the interlaced opening and closing of the two blades.
[0003] With the rapid development of e-commerce, online shopping has become an indispensable part of people's lives. Express packages arrive in a variety of forms, ranging from box-shaped to bubble bags. While traditional scissors can cut through transparent tape or packaging tape during the unpacking process, they are inconvenient to use. Users must first open the two blades of the scissors at an angle to expose the blades, then use only the cutting edge of one blade to perform the cut. This method is not only inefficient but also poses safety risks. Because the blade of the other blade is exposed during use, it can easily cause scratches to the hand. However, scissors are a common tool that users often use to unpack packages. For these reasons, cuts during unpacking are common.
[0004] Therefore, in order to overcome the deficiencies of the prior art, improve the convenience and safety of using scissors during the unpacking process, and expand the functions of the scissors, the present invention proposes a new type of multifunctional scissors. Utility Model Content
[0005] The purpose of the utility model is to provide a multifunctional pair of scissors with simple assembly, low cost, safe use, stable structure and easy operation, so as to solve the problems of the current scissors such as inconvenient unpacking, low safety, poor user experience and single function.
[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0007] A multifunctional pair of scissors comprises a first shearing piece and a second shearing piece hinged together by a rivet and capable of relative opening and closing, a first gripping portion connected to the first shearing piece, and a second gripping portion connected to the second shearing piece, wherein the first shearing piece comprises a guide hole and a first shearing edge, and the second shearing piece comprises a receiving hole and a second shearing edge. The scissors further comprise a slide, at least a portion of which is received in the guide hole and at least a portion of which is sleeved on the outside of the rivet. The slide can slide back and forth relative to the guide hole along the length extension direction of the scissors, thereby enabling relative movement of the first shearing piece and the second shearing piece along the length direction. The slide and the guide hole have two relative positions in which they can be stably matched:
[0008] In the first position, the front ends of the first cutting blade and the second cutting blade are staggered from each other, so that when the scissors are in the closed state, the front end of the first cutting edge or the second cutting edge can be exposed;
[0009] In the second position, the front ends of the first cutting piece and the second cutting piece overlap each other, so that when the scissors are in the closed state, the front ends of the first cutting edge and the second cutting edge can be hidden.
[0010] Furthermore, the rivet includes a column, which is sequentially inserted into the receiving hole and the guide hole.
[0011] Furthermore, the slide includes a clamping member and an elastic member, and the clamping member is sleeved around the column.
[0012] Furthermore, the elastic member can be deformed when the scissors are switched between the first position and the second position.
[0013] Furthermore, the elastic member includes an elastic cantilever and a positioning claw.
[0014] Furthermore, a first fixing groove and a second fixing groove are respectively provided on the guide hole along the length direction of the scissors, and the positioning claw can be engaged with or disengaged from the first fixing groove and the second fixing groove under the drive of the elastic cantilever.
[0015] Furthermore, when the positioning claw is engaged in the first fixing groove, the scissors are in the first position.
[0016] Furthermore, when the positioning claw is engaged in the second fixing groove, the scissors are in the second position.
[0017] Furthermore, the material of the sliding sheet is elastic plastic or elastic steel sheet.
[0018] Furthermore, the first gripping portion includes a first buffer seat, and the second gripping portion includes a second buffer seat. When the scissors are in a closed state, at least a portion of the first buffer seat abuts against the second buffer seat.
[0019] Furthermore, the rivet further includes a column head, the column head abuts against the first shear piece, and a gasket is sandwiched between the column head and the first shear piece.
[0020] Furthermore, the diameter of the gasket is larger than the diameter of the column head.
[0021] Furthermore, the gasket is made of plastic or metal.
[0022] Furthermore, the first gripping portion includes a first buckle, and the second gripping portion includes a second buckle. In the second position, the first buckle and the second buckle are staggered along the axial direction and do not interfere with each other, so that the scissors can be opened and closed freely. In the first position, the first buckle and the second buckle overlap at least partially along the axial direction, and the first buckle and the second buckle are hooked together, so that the scissors are locked and cannot be opened.
[0023] The utility model provides a multifunctional scissors, which has the following advantages over the prior art:
[0024] The sliding structure allows the two blades of the scissors to be staggered back and forth, while maintaining a stable structure. The staggered blades allow for expanded functions such as unpacking without opening the scissors, making the scissors more versatile. Unpacking with the scissors closed is safer and avoids the risk of cuts. At the same time, the scissors' structure remains compact without increasing its complexity.
[0025] The principle and structure of the structure are simple, the cost is low, and it is stable and reliable, which effectively solves the problem that the scissors are risky to use when unpacked and used in daily life, and are easy to cut hands. BRIEF DESCRIPTION OF THE DRAWINGS

The content is sufficient to enable any person skilled in the art to understand the technical content of the present invention and implement it accordingly. Based on the description, claims and drawings disclosed in this specification, those skilled in the art can easily understand the relevant purposes and advantages of the present invention.
[0069] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0070] In the description of this embodiment, it should be noted that the terms "front" and "rear" etc. indicating directions or positional relationships are defined with reference to the front tip of the scissors as the front end. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.
[0071] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.
[0072] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0073] Figure 1 It is a schematic diagram of an exploded view of a multifunctional scissors, which comprises in sequence: a first shearing piece 10, a second shearing piece 20, a first gripping portion 30, a second gripping portion 40, a rivet 50, a slide 60 and a gasket 90.
[0074] The tail end of the first shearing piece 10 is fixed to the front end of the first gripping portion 30, and the tail end of the second shearing piece 20 is fixed to the front end of the second gripping portion 40. The first gripping portion 30 and the second gripping portion 40 are both approximately semicircular in shape, used to accommodate the user's hand and perform operation. The first shearing piece 10 and the second shearing piece 20 are both slender in shape. The first shearing piece 10 includes a first shearing blade 12, and the second shearing piece 20 includes a second shearing blade 22. The first shearing piece 10 and the second shearing piece 20 are pivotally connected together by a rivet 50, and cutting is performed by opening and closing at different angles. When cutting is required, the item to be cut is placed between the first shearing blade 12 and the second shearing blade 22. The user gradually pinches the first gripping portion 30 and the second gripping portion 40, so that the first shearing blade 12 and the second shearing blade 22 gradually approach each other and cutting is achieved.
[0075] Optionally, the first clip 10 and the first grip 30, and the second clip 20 and the second grip 40, can be spliced, riveted, welded, or integrally formed. That is, the first clip 10 and the first grip 30, and the second clip 20 and the second grip 40 can be separate or integrally formed. Any joint method that enables synchronous rotation is acceptable.
[0076] Figure 8 The figure shows the assembly diagram of the first shear 10 and the first gripping portion 30. In the figure, the first gripping portion 30 is in the shape of the letter "b". The first shear 10 is slender and is inserted into the first gripping portion 30. Figure 10 , a partial enlarged view of the guide hole 11 included in the main body of the first shear 10. Figures 10-12 The guide hole 11 is a stepped hole structure as a whole, that is, it includes a large diameter section 113 and a small diameter section 114. The small diameter section 114 can just accommodate the sliding of the column 51 along the length direction without lateral displacement. The large diameter section 113 can accommodate at least a portion of the sliding plate 60, and the sliding plate 60 can slide relative to the large diameter section 113. During the sliding process, at least a portion of the sliding plate 60 rubs against the inner wall of the large diameter section 113. The large diameter section 113 has a first fixing groove 111 and a second fixing groove 112 on both sides along the length direction.
[0077] See also Figure 9 The figure shows the assembly diagram of the second shear 20 and the second gripping portion 40 . The main body of the second shear 20 includes a receiving hole 21 . The diameter of the receiving hole 21 is the same as that of the column 51 . The column 51 can only rotate in the receiving hole 21 but cannot deflect.
[0078] When the entire pair of scissors is assembled, the column 51 passes through the receiving hole 21, the slide 60, and the guide hole 11 in sequence, so that the rivet 50 can rotate relative to the second shear 20, and can both rotate and move back and forth relative to the first shear 10. The second grip 40 also includes a second buffer seat 41. When the scissors are in a fully closed state, at least a portion of the first buffer seat 31 and the second buffer seat 41 can offset each other, playing a role in limiting and stabilizing. And it is easy to understand that whether the scissors are in the first position or the second position, at least a portion of the first buffer seat 31 and the second buffer seat 41 can offset each other. The above-mentioned buffer seat is a common design of scissors and is therefore not described in detail.
[0079] In the above schematic diagram, the first scissors body and the second scissors body are axially symmetrical structures, and any asymmetric structural design of the first scissors body and the second scissors body that meets the above assembly requirements is acceptable.
[0080] Optionally, the positioning piece is made of elastic plastic material or elastic steel sheet.
[0081] Figure 6 、 Figure 7 This is a structural diagram of the slide 60. In this diagram, the slide 60 includes an arc-shaped clamping member 61, an elastic cantilever 63, and a positioning claw 64 located at the end of the elastic cantilever 63. A guide surface 65 is provided at the position where the positioning claw 64 engages with the first fixing groove 111 and the second fixing groove 112.
[0082] See also Figure 4 、 Figure 5 and Figure 11 、 Figure 12 . The column 51 of the rivet 50 passes through the clamping piece 61. The inner diameter of the clamping piece 61 is substantially the same as the outer diameter of the column 51, so that the column 51 can be clamped in the clamping piece 61. In addition, the clamping piece 61 has protrusions 66 extending in opposite directions along the circumferential direction, which further improves the reliability of the clamping piece and the stability of the scissors when switching between the first position and the second position. The setting of the guide surface 65 can not only play a guiding role when the consumer switches the state of the scissors, so that the positioning claw 64 can smoothly disengage the first fixing groove or the second fixing groove, but also make the first and second shears have a change in perception during the relative movement, so that the consumer can feel that the scissors have switched to different states.
[0083] Optionally, in some embodiments, the scissors further include a gasket 90, and a first buckle 31 is added to the first grip 30, and a second buckle 41 is added to the second grip 40. The gasket 90 is sandwiched between the column head 52 and the first shearing piece 10. Optionally, the diameter of the gasket 90 is larger than the diameter of the column head 52. The addition of the gasket 90 increases the area of the column head 52 covering the first shearing piece 10, making the scissors more stable when switching between forward and backward push states. Furthermore, due to the design of the gasket 90, since its diameter is larger than the diameter of the column head 52, the annular surface structure is exposed. By coloring the gasket, the visual effect of the product can be enriched and the product's interest can be enhanced.
[0084] Optionally, the gasket 90 is made of elastic material.
[0085] The structures of the first buckle 31 and the second buckle 41 are as follows: Figures 1 to 12 As shown, the first buckle 31 and the second buckle 41 are arranged in an "L" shape opposite to each other. Figure 3 、 Figure 5 In the second position, the first buckle and the second buckle are staggered in the axial direction and do not interfere with each other, and the scissors can open and close freely for cutting; Figure 4 Figure 6 As shown, in the first position, the first buckle and the second buckle overlap at least partially along the axial direction, and the first buckle and the second buckle are hooked together. At this time, the scissors are locked and cannot be opened, further improving the stability of the scissors during unpacking and paper cutting operations.
[0086] Optionally, the first buckle and the second buckle are not L-shaped, but may be C-shaped and arranged opposite to each other, or any other structure that can be fastened together and does not affect the movement of the scissors in the axial direction.
[0087] When the user staggers the first scissors body and the second scissors body front to back to expose the second cutting blade for opening the box, the scissors are locked and cannot be opened, thereby increasing the safety and convenience of opening the box with the scissors in the first position.
[0088] It is easy to understand that the first buckle and the second buckle both include openings at the top and bottom, that is, the first buckle and the second buckle will not interfere with the switching of the scissors between the overlapping state and the staggered state.
[0089] Here's how scissors work:
[0090] See also Figure 3 、 Figure 5 This is a schematic diagram of the scissors in the second position. In this state, the positioning claw 64 of the slide is engaged in the second fixed groove 112, and the first shearing blade 12 can be completely covered by the second shearing blade 20, and the second shearing blade 22 can also be completely covered by the first shearing blade 10. That is, in the second position, when the scissors are closed, the first shearing blade 12 and the second shearing blade 22 can be hidden. In this state, the multifunctional scissors can pivot and cut normally, and the usage state is basically the same as that of conventional scissors. In this state, the sharp parts of the first and second shearing blades are hidden. When operations such as unpacking and paper cutting are required, when the scissors are fully closed, the first gripping portion 30 is pulled backward along the entire length of the scissors. Due to the elastic action of the elastic arm 63 and the constraints of the inner walls on both sides of the large diameter section, the elastic arm 63 can swing inward, thereby causing the positioning claw 64 to disengage from the second fixed groove 112. Continue pulling until the positioning claw 64 is engaged in the first fixed groove 111. In this state, the front ends of the first and second shearing blades are staggered, and the exposed front end of the second shearing blade can be used to perform functions such as opening the box. Furthermore, due to the engagement of the positioning claw 64 with the first fixing slot 111, the scissors can remain stable without any external forces. Furthermore, due to the guiding effect of the guide surface, when the user needs to switch the scissors state, they can switch smoothly without much force. Furthermore, since a buckle is provided on the handle, the scissors can be locked in a closed state when in the first position, making the product structure more reliable and improving safety.
[0091] Industrial Applicability
[0092] In summary, the present invention provides a multifunctional pair of scissors. The sliding design allows the two blades of the scissors to move relative to each other and stagger, resulting in simple operation and a stable structure. The staggered blades allow for expanded functions such as unpacking without opening the scissors, enriching the scissors' functionality. Using closed scissors for unpacking is safer and avoids the risk of cuts. At the same time, the scissors' structural complexity is not increased, and the entire structure is compact.
[0093] The principle and structure of the structure are simple, the cost is low, and it is stable and reliable, which effectively solves the problems of high risk, inconvenience and easy hand cuts when unpacking and using scissors in daily life.
