[0101] In the description of this embodiment, it should be noted that the terms "upper" and "lower" and the like indicate orientations or positional relationships that are defined with reference to the coordinates of the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0102] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.
[0103] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0104] Figure 1 It is a schematic diagram of an exploded view of a multi-purpose scissors, which sequentially comprises: a first cutting piece 10, a second cutting piece 20, a first handle 30, a second handle 40, a positioning member 50 and a pin 90.
[0105] The tail end of the first shearing piece 10 is fixed together with the first handle 30 to form the first body 1, and the tail end of the second shearing piece 20 is fixed together with the second handle 40 to form the second body 2. The first handle 30 and the second handle 40 are both approximately annular, used to accommodate the user's hand and apply force. The first shearing piece 10 and the second shearing piece 20 are both slender, the first shearing piece 10 includes a first blade 11, and the second shearing piece 20 includes a second blade 21. The first shearing piece 10 and the second shearing piece 20 are pivotally connected together by a positioning member 50 and a pin 90, and cutting is performed by opening and closing at different angles. When cutting is required, the object to be cut is placed between the first blade 11 and the second blade 21, and the user gradually pinches the first handle 30 and the second handle 40 so that the first blade 11 and the second blade 21 gradually approach each other and cutting is achieved.
[0106] Optionally, the first clip 10 and the first handle 30, the second clip 20 and the second handle 40 can be plugged, riveted, welded, or can be an integrally formed structure. That is, the first clip 10 and the first handle 30, the second clip 20 and the second handle 40 can be designed separately or integrally formed. Any joining method that can achieve synchronous rotation is allowed.
[0107] Fig. 9 Fig.10 The first cutting piece 10 and the first handle 30 are shown as a schematic diagram of assembly. In this schematic diagram, the first handle 30 is in the shape of the letter "b". The first cutting piece 10 is slender and the first cutting piece 10 is inserted into the first handle 30. Fig.10It can be seen that the main body of the first shearing piece 10 includes a racetrack-shaped countersunk hole 12. The countersunk hole 12 includes a large diameter section 13 and a small diameter section 14. The first handle 30 also includes a first buffer seat 31, and the first buffer seat 31 also includes a first plane 32.
[0108] See also Fig.12 , wherein the large diameter section 13 can just accommodate the positioning piece, and the small diameter section 14 can just accommodate the rivet column 91 to slide therein without lateral displacement.
[0109] See also Fig.11 The figure shows a schematic diagram of the assembly of the second scissors 20 and the second handle 40. The second handle 20 includes an assembly hole 22 on its main body. The diameter of the assembly hole 22 is the same as that of the rivet column 91. The rivet column 91 can only rotate in the assembly hole 22 but cannot be offset. When the entire scissors are assembled, the rivet column 91 passes through the assembly hole 22, the positioning member and the small diameter section respectively, so that the rivet 90 can rotate relative to the second main body, and can rotate and move forward and backward relative to the first main body. The second handle 40 also includes a second buffer seat 41, and the second buffer seat 41 also includes a second plane 42. When the scissors are in a fully closed state, at least a portion of the first plane 32 and the second plane 42 can offset each other, which plays a role in limiting and stabilizing. And it is easy to understand that whether the scissors are in an overlapping state or an interlaced state, at least a portion of the first plane 32 and the second plane 42 can offset each other, and the buffer seat is the same design as that of common scissors, so it is not repeated.
[0110] In the above schematic diagram, the first body and the second body are in an axisymmetric structure, and any asymmetric structural design of the first body and the second body that meets the above assembly requirements is acceptable.
[0111] Optionally, the positioning piece is made of elastic plastic material or elastic steel sheet.
[0112] Embodiment 1:
[0113] Figure 5-6 The structure of the positioning member 50 in Example 1, the outer contour of the positioning member 50 is runway-shaped, and the first positioning hole 51 and the second positioning hole 52 are included inside, and a slide groove 55 is included between the first positioning hole 51 and the second positioning hole 52, and the first cantilever 53 and the second cantilever 54 are respectively arranged on the upper and lower sides of the slide groove 55. Due to the structural design of the cantilever and the material of the elastic plastic of the positioning member, the first cantilever 53 and the second cantilever 54 can swing when subjected to external force. The first cantilever 53 and the second cantilever 54 are also provided with a buffer zone 58 on the outside, and the buffer zone 58 is a horizontal hollow area. It is ensured that the first body 1 and the second body 2 will not slide smoothly due to insufficient cantilever deformation space during the relative sliding process.
[0114] The first positioning hole 51 and the second positioning hole 52 are respectively axially symmetrical arc holes. The diameters of the first positioning hole 51 and the second positioning hole 52 can match the rivet column 91, so that the rivet column 91 can rotate freely therein, and the distance D1 between the centers of the two positioning holes is the length that the second blade 21 can extend in the staggered state. D3 is the width of the slide groove, and the width of the slide groove D3 is smaller than the diameter of the rivet column 91. However, due to the cantilever design on both sides, when the rivet column 91 slides in the slide groove 55, the first cantilever 53 and the second cantilever 54 can swing outward to ensure the passage of the rivet column 91. The rivet 90 is prevented from being disengaged along the rivet column 91 in the axial direction by a rivet cap 92 whose diameter is larger than the first positioning hole 51 and the second positioning hole 52. Slide groove slopes 55a are provided on both sides of the slide groove 55 in the direction of transition to the first positioning hole 51 and the second positioning hole 52, which can not only serve as a guide when the consumer switches the scissors state, but also make the first body 1 and the second body 2 have a change in perception during the relative movement, so that the consumer can feel that the scissors have switched to different states.
[0115] Embodiment 2:
[0116] Figure 7-Figure 8 The structure of the positioning member 150 in Example 2, the positioning member 150 has a runway-shaped outer contour, and includes a first positioning hole 151 and a second positioning hole 152 inside, and a slide groove 155 between the first positioning hole 151 and the second positioning hole 152, and a first cantilever 153, a second cantilever 154, a third cantilever 156, and a fourth cantilever 157 are respectively arranged around the slide groove 155, wherein the first cantilever 153 and the third cantilever 156 and the second cantilever 154 and the fourth cantilever 157 both include a gap 159, and the setting of the gap 159 increases the elasticity of the cantilever, and since the gap 159 is narrow, it does not affect the sliding of the rivet column 91. Due to the structural design of the cantilever and the material of the elastic plastic of the positioning member, the first cantilever 53 and the second cantilever 54 can swing when subjected to external force. The first cantilever 153, the second cantilever 154, the third cantilever 155 and the fourth cantilever 156 are respectively provided with a buffer zone 158, which is a horizontal hollow area, to ensure that the first body 1 and the second body 2 will not slide smoothly due to insufficient cantilever deformation space during relative sliding.
[0117] The first positioning hole 151 and the second positioning hole 152 are respectively axially symmetrical arc holes, and the diameters of the first positioning hole 151 and the second positioning hole 152 can match the rivet column 91, so that the rivet column 91 can rotate freely therein, and the distance d1 between the centers of the two positioning holes is the length that the second blade 21 can extend in the staggered state. d3 is the width of the slide groove, which is smaller than the diameter of the rivet column 91. However, due to the cantilever design on both sides, when the rivet column 91 slides in the slide groove 155, the first cantilever 153, the second cantilever 154, the third cantilever 156 and the fourth cantilever 157 can swing outward, thereby ensuring the passage of the rivet column 91. The rivet 90 is prevented from being disengaged along the axial direction of the rivet column by a rivet cap 92 whose diameter is larger than the first positioning hole 151 and the second positioning hole 152. Slide groove slopes 155a are provided on both sides of the slide groove 155 in the direction of transition to the first positioning hole 151 and the second positioning hole 152, so that there is a change in perception during the relative movement of the first body 1 and the second body 2, allowing consumers to feel that the scissors have switched to different states.
[0118] Embodiment 3:
[0119] Figure 14 to Figure 17 The structure of the multi-purpose scissors in Example 3 is shown in Figure 3. Based on Examples 1 and 2, a gasket 70 is added to Example 3, and a first hook 33 is added to the first handle 30, and a second hook 43 is added to the second handle 40. The gasket 70 is sandwiched between the rivet cap 92 and the first shearing piece 10. Optionally, the diameter of the gasket 70 is larger than the diameter of the rivet cap 92. By adding the gasket 70, the area of the countersunk hole covered by the rivet cap is expanded, and the scissors are more stable when switching between the forward and backward pushing states. And through the design of the gasket 70, refer to Fig.15 Since its diameter is larger than the diameter of the rivet cap, the annular surface structure will be exposed. By painting the gasket, the visual effect of the product can be enriched and the interest of the product can be enhanced.
[0120] Optionally, the gasket 70 is made of elastic material.
[0121] The structures of the first hook 33 and the second hook 43 are as follows: Figure 14 to Figure 17 As shown, the first hook 33 and the second hook 43 are arranged opposite to each other in an "L" shape. Fig.15 As shown, in the overlapped state, the first hook and the second hook are staggered in the axial direction and do not interfere with each other, and the scissors can open and close freely for cutting; Fig.16 Fig.17 As shown, in the staggered state, the first hook and the second hook overlap at least partially along the axial direction, and the first hook and the second hook are hooked together, and the scissors are locked and cannot be opened.
[0122] Optionally, the first hook and the second hook, in addition to being L-shaped, may also be relatively arranged in a C-shape or any other structure that can be engaged and does not affect the movement of the scissors in the axial direction.
[0123] When the user staggers the first body and the second body front and back to expose the second blade to open the box, the scissors are locked and cannot be opened, thereby increasing the safety and convenience of opening the box in the staggered state.
[0124] It is easy to understand that the first hook and the second hook both include openings at the top and the bottom, that is, the first hook and the second hook will not interfere with the switching of the scissors between the overlapping state and the staggered state.
[0125] The scissors work as follows:
[0126] See also Figure 2 The scissors are in the overlapping state. In this state, the first blade 11 can completely cover the projection surface of the second blade 20, and the second blade 21 completely covers the projection surface of the first blade 10. The projection direction is perpendicular to the planes of the first blade 10 and the second blade 20. The rivet column 91 passes through the assembly hole, the positioning piece set in the large diameter section 13, and the small diameter section 14 respectively. In this state, the scissors can pivot and cut normally. When unpacking and other operations are required, when the scissors are fully closed, pull the first body 1 backward along the entire length of the scissors. The rivet column 91 can only rotate in the assembly hole 22 relative to the second body 2 and cannot move. At this time, the first body 1 drives the positioning piece 50 to move backward as a whole, and the relative rivet column 91 slides from the second positioning hole through the slide groove to the first positioning hole, thereby entering. Figure 3 The scissors are in a staggered state. In this state, the exposed part of the second blade can be used to perform functions such as opening the box. And because the width of the slide is smaller than the rivet column, the rivet column can remain stable whether in the first positioning hole or the second positioning hole without any other external force. And because of the guiding effect of the slide slope, when the user needs to switch the scissors state, the switch can be completed smoothly without much force. And because a buckle is provided on the handle, the scissors can be locked in a closed state when they are in a staggered state, the product structure is more reliable and safety is improved.
[0127] Industrial Applicability
[0128] In summary, the utility model provides a multi-purpose scissors. Through the design of the positioning member structure, the two blades of the scissors can be staggered, the operation is simple, and the structure is stable. The staggered blades can be opened without opening the scissors, and the functions of the scissors are more abundant. It is safer to unpack the closed scissors, avoiding the risk of cuts. At the same time, the complexity of the scissors structure is not increased, and the entire scissors structure is compact.
[0129] 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 at high risk of being unpacked and used in daily life, and are easy to cut hands.
