Description
Technical Field
The invention relates to an office appliance, in particular to a two-in-one cutting knife for cutting paper.
Background
Conventionally, when cutting a sheet, it is common to press a straight edge placed on the sheet with one hand and then cut the sheet along the edge of the straight edge with the other hand holding a blade. However, the cutting method is easy to scratch fingers and scratch the ruler or the table top.
Therefore, chinese patent publication No. CN 205521581U discloses a conventional paper knife, which comprises a fixed seat marked with scales, a pulley groove disposed in the fixed seat, a pulley slidably disposed in the pulley groove, a blade seat connected to the pulley, and a blade mounted on the blade seat.
When a user wants to use the existing paper knife, the blade seat is moved to drive the pulley to slide along the pulley groove, so that the blade can cut paper sheets along a straight line, and the blade can be prevented from being scraped to the ruler. In addition, the blade of the conventional paper knife is mounted on the blade seat by a screw, so that the inclination angle of the blade can be adjusted.
However, the existing paper cutters still have the following disadvantages:
firstly, the pulley groove is positioned at one side of the blade seat, and the situation that the cutting line is inclined is easy to generate when thicker or harder paper is cut.
Second, the blade changes the inclination angle of the blade by adjusting the screw, so the inclination angle of the blade can be confirmed only by visual means, and the cutting quality is easily affected by the angular deviation when cutting thick or hard paper.
Thirdly, the existing paper cutter can not adjust the cutting depth, so that the desktop is easily scratched.
Fourthly, the blade is opposite to one side of pulley groove opens outwards, scratch finger easily.

The positioning member has an outer end portion relatively distant from the other side surface. When the adjusting plate is at the second position, the positioning piece can be operated to move between a positioning position and a non-positioning position relative to the corresponding side plate along the extending direction of the positioning hole. When the positioning piece is at the positioning position, the outer end part is relatively far away from the other side plate and abuts against the corresponding side plate, so that the adjusting plate cannot rotate towards the first position. When the positioning piece is at the non-positioning position, the outer end part relatively approaches to the other side plate, so that the adjusting plate can rotate towards the first position.
The two-in-one cutting knife is characterized in that the adjusting plate of the adjusting seat is also provided with a working surface and a bearing surface which are arranged around the rotating axis and are opposite to each other. The sliding groove is concavely arranged on the working surface. When the adjusting plate is at the first position, the bearing surface abuts against the base plate.

The base plate of base still have connect between the top surface with the bottom surface and preceding terminal surface open forward, and the concave ruler groove of establishing that locate preceding terminal surface just is applicable to supplying ruler is at least partially inserted. The two opposite ends of the blade groove along the rotation axis are open.
The cutting unit also comprises a pushing piece which is arranged in the sliding groove in a sliding way so as to drive the blade to move along the sliding groove, and at least one elastic piece which is arranged between the pushing piece and the adjusting plate. The at least one elastic piece can generate force which is forced to abut against the pushing piece and the adjusting plate.
The two-in-one cutting knife of the invention defines that the sliding groove of the adjusting seat extends along the sliding axis. The cutting unit further comprises two of the elastic members. The elastic pieces are arranged at intervals along the extending direction of the rotating axis. Each elastic piece is provided with two connecting parts which are arranged along the extending direction of the sliding axis in an opposite way and are connected with the pushing piece, and a pressing part which is positioned between the connecting parts and protrudes out of the pushing piece to be pressed against the adjusting plate.
According to the two-in-one cutting knife, the sliding groove of the adjusting seat is provided with a cutting section relatively approaching to the substrate, a free section opposite to the cutting section, and a stopping section which is located between the cutting section and the free section and is wider than the cutting section and the free section. When the pushing piece moves to enable the pressing and abutting parts of the elastic piece to correspond to the stopping sections, the distance between the pressing and abutting parts is larger than the width of the cutting section and the width of the free section.
The invention has the beneficial effects that: because the adjusting plate is pivoted between the side plates, the cutting line is not easy to shake in the cutting process, and the cutting line is prevented from being inclined. When the adjusting plate rotates between the first position and the second position, the angle of the extending direction of the blade and the base plate can be changed, and each guide column can synchronously rotate between the first end area and the second end area, so that the blade can be ensured to be inclined to a preset angle.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
Referring to fig. 1 to 3 and fig. 8, an embodiment of the two-in-one cutting knife of the present invention is adapted to abut against a straight edge 11 and cut a sheet of paper 12.
The two-in-one cutting knife comprises a base 2, an adjusting seat 3 and a cutting unit 4.
The base 2 includes a base plate 21, two side plates 22 disposed on the base plate 21 at intervals along a rotation axis L1, two guide grooves 23 formed on the side plates 22, and two deformation grooves 24 recessed in the side plates 22 and adjacent to each other and corresponding to the guide grooves 23.
The base plate 21 has a top surface 211, a bottom surface 212, two through holes 213 penetrating through the top surface 211 and the bottom surface 212, a front end surface 214 connected between the top surface 211 and the bottom surface 212 and opened forward, and a ruler slot 215 recessed in the front end surface 214 and adapted for at least partially inserting the ruler 11. The blade groove 215 is open at opposite ends along the rotation axis L1.
The side plate 22 is made of flexible material. Each guide groove 23 and each deformation groove 24 are formed on a side of the corresponding side plate 22 adjacent to the other side plate 22.
Each guide slot 23 is curved about the rotation axis L1 and has a first end region 231 and a second end region 232 which are arranged opposite to each other, an intermediate region 233 which is located between the first end region 231 and the second end region 232, a first neck region 234 which communicates between the first end region 231 and the intermediate region 233, and a second neck region 235 which communicates between the second end region 232 and the intermediate region 233.
Each side plate 22 has two annular surfaces 221 which respectively surround and define the guide groove 23. The annular groove surface 221 has an outer portion 222 relatively distant from the rotation axis L1, an inner portion 223 relatively close to the rotation axis L1 and disposed opposite to the outer portion 222, and two end portions 224 spaced apart and disposed opposite to each other and connecting the outer portion 222 and the inner portion 223. The inner portions 223 corresponding to the first and second neck regions 234, 235 are closer to the outer portion 222 than the inner portions 223 corresponding to the middle region 233, the first end region 231, and the second end region 232, so that the groove widths of the first and second neck regions 234, 235 are smaller than the groove widths of the middle region 233, the first end region 231, and the second end region 232.
Each of the deformation grooves 24 is curved around the rotation axis L1 and extends in a length corresponding to the corresponding guide groove 23 and adjacent to the inner side portion 223 of the corresponding guide groove 23.
The adjusting seat 3 includes an adjusting plate 31 pivotally disposed between the side plates 22 along the rotation axis L1, a sliding slot 32 concavely disposed on the adjusting plate 31, two guiding posts 33 disposed on the adjusting plate 31 and movably extending into the guiding slots 23, two positioning holes 34 disposed on the adjusting plate 31 (fig. 2 and 3 only disclose one positioning hole 34, please refer to fig. 5), and two positioning members 35 respectively passing through the positioning holes 34. The runner 32 defining the adjustment seat 3 extends along a sliding axis L2. The sliding axis L2 is perpendicular to the rotating axis L1. The first and second neck regions 234 and 235 of each guide slot 23 have a slot width less than the diameter of the corresponding guide post 33.
Referring to fig. 1 to 4, the adjusting plate 31 is formed with a working surface 311 and a bearing surface 312 oppositely disposed around the rotation axis L1, and two side surfaces 313 oppositely disposed and spaced along the rotation axis L1 and connected between the working surface 311 and the bearing surface 312. The sliding groove 32 is concavely arranged on the working surface 311.
In this embodiment, the adjusting plate 31 has a first plate portion 314 for the chute 32 to be recessed, and two second plate portions 315 spaced apart from each other along the rotation axis L1 and extending downward from the first plate portion 314 and respectively corresponding to the side plates 22 of the base 2. The working surface 311 is formed on the first plate portion 314, and the bearing surface 312 and the side surface 313 are formed on the second plate portion 315.
The guiding pillars 33 are respectively disposed on the side surfaces 313. The positioning holes 34 pass through the side surfaces 313 of the second plate portion 315, respectively.
The positioning member 35 has an outer end 351 relatively far from the other side 313 and an inner end 352 relatively close to the other side 313.
The chute 32 has a cutting section 321 relatively approaching the base plate 21, a free section 322 opposite to the cutting section 321, and a resting section 323 located between the cutting section 321 and the free section 322 and having a width larger than the cutting section 321 and the free section 322.
The cutting unit 4 includes a blade 41 disposed on the sliding slot 32, a pushing member 42 slidably disposed on the sliding slot 32 to drive the blade 41 to move along the sliding slot 32, and two elastic members 43 disposed between the pushing member 42 and the adjusting plate 31 and spaced apart from each other along the extending direction of the rotation axis L1. The blade 41 can be driven to move along the sliding slot 32 by operating the pushing element 42, and the blade 41 can alternatively pass through the through hole 213 and partially protrude from the side of the base plate 21 opposite to the adjusting seat 3.
In the present embodiment, each elastic member 43 is an elastic sheet, and has two connecting portions 431 opposite to each other along the extending direction of the sliding axis L2 and connected to the pushing member 42, and a pressing portion 432 located between the connecting portions 431 and protruding from the pushing member 42 to be capable of pressing against the adjusting plate 31.
The elastic member 43 can generate a force to urge against the pushing member 42 and the adjusting plate 31. When the pushing element 42 moves to make the pressing portion 432 of the elastic element 43 correspond to the resting section 323, the distance between the pressing portions 432 is greater than the width of the cutting section 321 and the free section 322, so that the blade 41 can be kept at a height away from the through hole 213. When the pushing element 42 is pushed by a force to move downward, the elastic element 43 deforms to conform to the width of the cutting segment 321, and accumulates a restoring force to urge against between the pushing element 42 and the adjusting plate 31, so that the pushing element 42 is positioned along the sliding axis L2 relative to the adjusting plate 31.
Referring to fig. 1, 3, 5 and 6, the adjusting plate 31 can be operated to rotate around the rotation axis L1 between a first position and a second position relative to the base plate 21.
When the adjusting plate 31 is in the first position (see fig. 1 and 3), the adjusting plate 31 relatively approaches the substrate 21, the bearing surface 312 abuts against the substrate 21, the guiding pillars 33 are respectively located at the first end regions 231 of the guiding grooves 23, and a first angle θ 1 is defined between the blade 41 and the extending direction of the substrate 21. In the present embodiment, the first angle θ 1 is 45 degrees.
When the adjusting plate 31 is at the second position (see fig. 5 and 6), the adjusting plate 31 is relatively away from the base plate 21, the guiding pillars 33 are respectively located at the second end regions 232 of the guiding grooves 23, and a second angle θ 2 greater than the first angle θ 1 is defined between the extending directions of the blade 41 and the base plate 21. In the present embodiment, the second angle θ 2 is 90 degrees.
Referring to fig. 2, 5, and 7, when the adjusting plate 31 is at the second position, each positioning element 35 can be operated to move between a positioning position and a non-positioning position relative to the corresponding side plate 22 along the extending direction of the positioning hole 34. When the positioning member 35 is in the positioning position (see fig. 5), the outer end 351 is relatively far away from the other side plate 22 and abuts against the corresponding side plate 22, so that the adjusting plate 31 cannot rotate towards the first position. When the positioning member 35 is in the non-positioning position (fig. 7), the outer end portion 351 approaches the other side plate 22 relatively to enable the adjusting plate 31 to rotate towards the first position.
Referring to fig. 1 to 3, 6 and 8, before a user uses the two-in-one cutting knife, the adjusting plate 31 is first rotated to the first position shown in fig. 3 or the second position shown in fig. 6 according to the cutting requirement.
When the adjusting plate 31 rotates between the first position and the second position, each guiding column 33 moves in the corresponding guiding slot 23. When each guide post 33 moves to a position corresponding to the first neck region 234, since the diameter of each guide post 33 is larger than the groove width of the first neck region 234, each guide post 33 will force the inner portion 223 of the corresponding groove surface 221 to deform the inner portion 223 toward the corresponding deformation groove 24, so that the groove width of the first neck region 234 is enlarged for each guide post 33 to pass through. After each guide pillar 33 passes through, the inner portion 223 is restored to the original position by the characteristic of the flexible material, that is, the groove width of the first neck region 234 is restored to the original width. Therefore, after each guiding column 33 moves to the first end region 231, under the condition of no external force, each guiding column 33 is limited at the first end region 231 because the groove width of the first neck region 234 is narrower, that is, the adjusting plate 31 is limited at the first position. Similarly, when each guide post 33 moves to the second end portion 232, the second end portion 232 is retained by the narrow groove width of the second neck portion 235, i.e. the adjustment plate 31 is retained in the second position.
In addition, when the adjusting plate 31 is rotated to the second position as shown in fig. 6, the user may further operate each positioning member 35 to the positioning position, so that the adjusting plate 31 cannot rotate toward the first position, and thus the effect of limiting the adjusting plate 31 to the second position can be further enhanced.
After the user rotates the adjusting plate 31 to the first position or the second position according to the above-mentioned steps, the two-in-one cutting knife can be used to cut the paper 12. First, the user needs to place the two-in-one cutting knife on the paper 12, insert the straight ruler 11 into the ruler slot 215, and then push the pushing element 42 to move downward to drive the blade 41 to move along the sliding slot 32, so that the blade 41 passes through the corresponding through hole 213 (see the position of the blade 41 marked by the two-dot chain line in fig. 3 and 6) and abuts against the paper 12, and then cutting can be performed.
During cutting, the user can press the straight edge 11 with one hand and operate the two-in-one cutting knife to slide relative to the straight edge 11 with the other hand, so that the paper 12 can be cut along a straight line. In addition, during cutting, the user can also confirm and control the cutting distance according to the scales (not shown) marked on the ruler 11.
After the user finishes cutting, the two-in-one cutting blade can be removed from the paper 12 by pushing the pushing element 42 to move upward, so that the pressing part 432 of the elastic element 43 corresponds to the stopping section 323.
It should be noted that, when the pressing portion 432 of the elastic member 43 corresponds to the resting section 323, the distance between the pressing portions 432 is greater than the widths of the cutting section 321 and the free section 322, so that the pushing member 42 and the blade 41 do not move along the sliding slot 32 without being subjected to an external force, and the blade 41 can be kept at a height away from the through hole 213, so as to prevent the blade 41 from penetrating through the through hole 213 and cutting the user or other objects.
In addition, after the pushing element 42 is pushed to drive the blade 41 to move downwards along the sliding slot 32, the elastic element 43 is deformed and is forced to abut between the pushing element 42 and the adjusting plate 31, so that the pushing element 42 is positioned relative to the adjusting plate 31 along the sliding axis L2, and therefore before cutting, the user can adjust the length of the blade 41 protruding from the base plate 21 according to the thickness of the paper 12, so as to avoid cutting a table top.
It should be noted that, because the adjusting plate 31 is pivoted between the side plates 22, in addition, the adjusting plate 31 is in the first position, the bearing surface 312 is abutted against the base plate 21, and the adjusting plate 31 is in the limiting effect of each positioning member 35 in the second position, and the limiting effect of each guiding groove 23 generated by the first neck region 234 and the second neck region 235 on the corresponding guiding column 33, the adjusting plate 31 is not easy to shake in the cutting process, so as to avoid the cutting line being inclined.
In addition, the two-in-one cutting knife changes the angle of the extending direction of the blade 41 and the base plate 21 by rotating the adjusting plate 31 between the first position and the second position, and each guiding column 33 rotates between the first end section 231 and the second end section 232 synchronously during the rotation of the adjusting plate 31, so that the blade 41 can be ensured to be inclined to a predetermined angle.
In addition, in other embodiments, the substrate 21 may be made of a transparent or translucent material, so that the user can simultaneously view the length of the cutting line during the cutting process, and the situation that the scale marked on the ruler 11 is hidden by the substrate 21 and the length of the cutting line cannot be confirmed can be avoided.
It should be noted that in the present embodiment, the base 2 includes two deformation slots 24, and each deformation slot 24 is curved around the rotation axis L1 and extends for a length corresponding to the corresponding guide slot 23, however, the base 2 is not limited thereto, in other implementation aspects, the base 2 may also include four deformation slots 24, wherein two deformation slots 24 are disposed on one side plate 22 and correspond to the first neck region 234 and the second neck region 235 of the corresponding guide slot 23, and the other two deformation slots 24 are disposed on the other side plate 22 and correspond to the first neck region 234 and the second neck region 235 of the other guide slot 23, and the shape of the deformation slots 24 is not limited to the curved arc, as long as when each guide pillar 33 presses against the inner side portion 223 of the corresponding slot surface 221, a space for facilitating deformation is provided, the same object can be achieved.
It should be noted that, in this embodiment, the base plate 21 has two through holes 213, so that when the adjusting plate 31 rotates to the first position and the second position, the blade 41 can respectively pass through the through holes 213, and by such a design, the circumference of the blade 41 can be kept surrounded by the base plate 21, thereby preventing the hand of the user from being accidentally cut during the cutting process. In other embodiments, the through holes 213 may be communicated with each other, that is, only one through hole 213 needs to be provided on the base plate 21, and the same purpose can be achieved as long as the through hole 213 can allow the blade 41 to pass through when the adjusting plate 31 rotates to the first position and the second position. It is understood that the number of the positioning holes 34 and the number of the elastic members 43 may be one, and when the number of the positioning holes 34 is one, the positioning holes 34 pass through one side surface 313.
In summary, the two-in-one cutting knife of the present invention can prevent the cutting line from being inclined by pivotally installing the adjusting plate 31 between the side plates 22 and not easily swaying during the cutting process. When the adjusting plate 31 is rotated between the first position and the second position, the angle between the blade 41 and the extending direction of the base plate 21 can be changed, and since each guide post 33 is synchronously rotated between the first end zone 231 and the second end zone 232, the blade 41 can be ensured to be inclined to a predetermined angle, thereby achieving the purpose of the present invention.
The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made by the claims and the contents of the specification are included in the scope of the present invention.
