[0034] Please refer to Figures 1 to 6 The cutting device 10 provided in the embodiment of the present application includes a fixing component 100 and a cutting component 200. The cutting device 10 can be used to cut an object 20 to be cut, and is particularly suitable for scenes where the object 20 to be cut needs to be organized and neatly arranged. For example, the object 20 to be cut can be various types of items such as paper boxes, paper sheets, plastic plates, and tapes.

[0035] The fixing assembly 100 is used to install and fix the cutting assembly 200, and is used for an operator to hold it to perform a cutting operation. The fixing assembly 100 includes a first fixing member 110 and a second fixing member 120, at least a portion of the first fixing member 110 is spaced apart from the second fixing member 120 and encloses a receiving cavity 130, and a hollow receiving cavity 130 is provided between the first fixing member 110 and the second fixing member 120.

[0036] The cutting assembly 200 is used to cut the object 20 to be cut. Exemplarily, the cutting assembly 200 can be set as a sharper blade-like structure. The cutting assembly 200 is arranged in the accommodating cavity 130 and is connected to the first fixing member 110 and / or the second fixing member 120, and at least part of the cutting assembly 200 protrudes from the accommodating cavity 130. Specifically, part of the cutting assembly 200 is located in the accommodating cavity 130 and is connected to the first fixing member 110 through the accommodating cavity 130, or is connected to the second fixing member 120 through the accommodating cavity 130, or is connected to both the first fixing member 110 and the second fixing member 120 through the accommodating cavity 130; another part of the cutting assembly 200 extends out of the accommodating cavity 130 to contact the object 20 to be cut and cut the object 20 to be cut.

[0037] Based on the above structural design, since the fixing assembly 100 includes the first fixing member 110 and the second fixing member 120, when assembling the cutting device 10, the first fixing member 110, the cutting assembly 200 and the second fixing member 120 can be assembled in sequence, or the first fixing member 110 and the second fixing member 120 can be assembled first, and then the cutting assembly 200 is installed in the accommodating cavity 130 between the first fixing member 110 and the second fixing member 120. The assembly method is flexible, the operation is simple, and the assembly and maintenance efficiency is high. In addition, the cutting assembly 200 is inserted into the accommodating cavity 130 between the first fixing member 110 and the second fixing member 120, and the cutting assembly 200 is connected to the first fixing member 110 and / or the second fixing member 120, then the cutting assembly 200 can be stably clamped by the first fixing member 110 and the second fixing member 120, thereby ensuring the stability of the connection between the cutting assembly 200 and the fixing assembly 100, effectively avoiding the problem that the cutting assembly 200 is separated from the fixing assembly 100, causing damage to the cutting device 10, or even affecting the safety of the operator.

[0038] As a further preferred implementation scheme, based on the above scheme, the specific embodiments of the present application may also include one or more of the following additions or combinations.

[0039] In some optional embodiments, the first fixing member 110 and the second fixing member 120 are manufactured and formed separately, so as to facilitate the assembly of the first fixing member 110 and the second fixing member 120 with the cutting assembly 200 .

[0040] Further, in some optional embodiments, the first fixing member 110 and the second fixing member 120 are detachably connected. Exemplarily, the first fixing member 110 and the second fixing member 120 can be detachably connected by bolt connection, snap connection, or the like. Since the first fixing member 110 and the second fixing member 120 are detachable, on the one hand, it is convenient to flexibly assemble the first fixing member 110 and the second fixing member 120 with the cutting assembly 200, and on the other hand, it is convenient to disassemble and maintain the damaged cutting device 10, which is beneficial to prolong the service life of the cutting device 10 and reduce the replacement cost of the cutting device 10.

[0041] It is understood that in other optional embodiments, the first fixing member 110 and the second fixing member 120 may also be connected in a non-detachable manner. For example, the first fixing member 110 and the second fixing member 120 may also be directly welded. In this case, although the first fixing member 110 and the second fixing member 120 are non-detachable, the connection strength between the first fixing member 110 and the second fixing member 120 is relatively high, and the assembly requirements of the cutting device 10 can also be met.

[0042] It should be added that, based on comprehensive factors such as cutting effect and production cost, in the actual production process, a structural form in which the first fixing member 110 and the second fixing member 120 are detachably connected is preferred.

[0043] In some optional embodiments, the first fixing member 110 includes a gripping portion 111 and a fixing portion 112, the gripping portion 111 is connected to the fixing portion 112, the fixing portion 112 is connected to the second fixing member 120 and forms a receiving cavity 130 with the second fixing member 120. When it is necessary to cut the object 20 to be cut, the operator can hold the gripping portion 111 to facilitate the cutting operation. In addition, since the fixing portion 112 is connected to the second fixing member 120 to form the receiving cavity 130, the gripping portion 111 is connected to the cutting assembly 200 through the fixing portion 112 and the second fixing member 120, so that the gripping portion 111 is spaced apart from the cutting assembly 200. Therefore, when the operator holds the gripping portion 111, the operator's hand can maintain a certain distance from the cutting assembly 200, so as to avoid the risk of the cutting assembly 200 scratching the operator.

[0044] For example, refer to Figure 2 and Figure 4 The gripping portion 111 is configured as an arc-shaped structure, which is wider at both ends and narrower in the middle, and its side surface is a smooth and continuous arc-shaped surface, so that the operator's hand fits the gripping portion 111 easily, so that the operator can hold the gripping portion 111 more firmly, and avoid the hand sliding forward and causing the cutting assembly 200 to scratch the hand, or the hand sliding backward and causing the cutting device 10 to fall off the hand, so that the cutting operation can be carried out smoothly, the operation is smooth and comfortable, and it is also safe.

[0045] In some optional embodiments, the fixing portion 112 includes a first fixing segment 112a and a second fixing segment 112b, the second fixing segment 112b is connected to the first fixing segment 112a and the holding portion 111 in sequence, the thickness of the second fixing segment 112b is less than the thickness of the first fixing segment 112a, and the thickness of the first fixing segment 112a is less than the thickness of the holding portion 111; the second fixing member 120 includes a third fixing segment 121 and a fourth fixing segment 122, the third fixing segment 121 is connected to the first fixing segment 112a, the fourth fixing segment 122 is connected to the third fixing segment 121 and forms a accommodating cavity 130 with the second fixing segment 112b. Since the thicknesses of the holding portion 111, the first fixing section 112a and the second fixing section 112b decrease successively, a step structure is formed between the holding portion 111 and the first fixing section 112a, and between the first fixing section 112a and the second fixing section 112b. This facilitates precise positioning of the third fixing section 121 and the fourth fixing section 122 with the first fixing section 112a and the second fixing section 112b, respectively, thereby improving the assembly efficiency of the fixing portion 112 and the second fixing member 120.

[0046] For ease of understanding, the following Figure 4 The cutting device 10 in a specific embodiment of the present application is introduced. In the figure, the X direction is the length direction, the Y direction is the width direction, and the Z direction is the thickness direction. The length, width and thickness in the following text can be understood according to the directions shown in the figure, and will not be described in detail later.

[0047] Reference Figure 4 The gripping portion 111, the first fixing section 112a and the second fixing section 112b are sequentially arranged along the X direction, i.e., the length direction, wherein the first fixing section 112a is in a substantially trapezoidal structure, the second fixing section 112b is in a substantially triangular structure, and the second fixing section 112b is arranged to gradually decrease from near to far from the first fixing section 112a. The gripping portion 111, the first fixing section 112a and the second fixing section 112b are coplanar on one side in the Z direction, i.e., the thickness direction, and form a stepped structure on the other side.

[0048] The third fixing section 121 is configured as a trapezoidal structure adapted to the first fixing section 112a, and the fourth fixing section 122 is configured as a triangular structure adapted to the second fixing section 112b and forms a triangular accommodating cavity 130 with the second fixing section 112b. The third fixing section 121 overlaps with the orthographic projection of the first fixing section 112a on the XY plane, and the fourth fixing section 122 overlaps with the orthographic projection of the second fixing section 112b on the XY plane. In addition, the thickness of the third fixing section 121 is less than the thickness of the fourth fixing section 122, so that the third fixing section 121 and the fourth fixing section 122 are coplanar on one side in the Z direction, i.e., the thickness direction, and form a stepped structure on the other side.

[0049] Therefore, by designing the fixing portion 112 and the second fixing member 120 as the above-mentioned structural form, it is beneficial to accurately align the first fixing section 112a with the third fixing section 121, so as to facilitate the assembly positioning of the fixing portion 112 and the second fixing member 120, thereby improving the assembly efficiency.

[0050] In some optional embodiments, the first fixing section 112a is provided with a first fixing hole 112c, and the third fixing section 121 is provided with a third fixing hole 123 corresponding to the first fixing hole 112c; the fixing assembly 100 further includes a first connecting member 140, which is passed through the first fixing hole 112c and the third fixing hole 123 and is used to connect the first fixing section 112a and the third fixing section 121. By cooperating with the first connecting member 140, the first fixing hole 112c and the third fixing hole 123, the assembly and disassembly of the first fixing member 110 and the second fixing member 120 can be realized, and the operation efficiency is high.

[0051] Refer to Figure 4 In some embodiments, two first fixing holes 112c are provided on the first fixing section 112a along the Y direction, and two third fixing holes 123 are provided on the third fixing section 121 along the Y direction. The fixing assembly 100 further includes two first connecting members 140, and the first connecting members 140 are provided in a one-to-one correspondence with the first fixing holes 112c and the third fixing holes 123. Exemplarily, the first fixing holes 112c and the third fixing holes 123 may be threaded holes, and the first connecting member 140 may be a bolt-like structure, so that the first connecting member 140 may be threadedly connected with the first fixing hole 112c and the third fixing hole 123 by rotating the first connecting member 140, thereby facilitating the assembly and disassembly of the first fixing member 110 and the second fixing member 120.

[0052] It should be understood that in other optional embodiments, the number of the first fixing hole 112c, the third fixing hole 123 and the first connecting member 140 is not limited to the above examples. For example, the number of the first fixing hole 112c, the third fixing hole 123 and the first connecting member 140 can also be one, three, four, five, etc.

[0053] Further, in some optional embodiments, the second fixing section 112b is provided with a second fixing hole 112d, the fourth fixing section 122 is provided with a fourth fixing hole 124 corresponding to the second fixing hole 112d, and the cutting assembly 200 is provided with a connecting hole 211; the fixing assembly 100 further includes a second connecting member 150, which is passed through the second fixing hole 112d, the connecting hole 211 and the fourth fixing hole 124, and is used to set at least part of the cutting assembly 200 in the accommodating cavity 130. By the second connecting member 150 cooperating with the second fixing hole 112d and the fourth fixing hole 124, the effective connection between the cutting assembly 200 and the first fixing member 110 and the second fixing member 120 can be achieved, and at the same time, the connection is ensured to be stable, so as to prevent the cutting assembly 200 from shaking during cutting.

[0054] Reference Figure 4 and Figure 5 In some embodiments, two second fixing holes 112d are arranged on the second fixing section 112b along the Y direction, two fourth fixing holes 124 are arranged on the fourth fixing section 122 along the Y direction, and two connecting holes 211 are arranged on the cutting assembly 200 along the Y direction. The fixing assembly 100 further includes two second connecting members 150, and the second connecting members 150 are arranged in a one-to-one correspondence with the second fixing holes 112d, the fourth fixing holes 124, and the connecting holes 211. Exemplarily, the second fixing holes 112d, the fourth fixing holes 124, and the connecting holes 211 may be threaded holes, and the second connecting member 150 may be a structure similar to a bolt, so that the second connecting member 150 may be threadedly connected with the second fixing holes 112d, the fourth fixing holes 124, and the connecting holes 211 by rotating the second connecting member 150, thereby facilitating the fixing of the cutting assembly 200 in the accommodating cavity 130 between the first fixing member 110 and the second fixing member 120.

[0055] Of course, in other optional embodiments, the number of the second fixing hole 112d, the fourth fixing hole 124, the connecting hole 211 and the second connecting member 150 may also be one, three, four, five, etc.

[0056] In some optional embodiments, the first fixing member 110 further includes a mounting portion 113, and the mounting portion 113 is provided with a mounting through hole 113a, through which the cutting device 10 can be hung in a specific place, so as to facilitate the storage and organization of the cutting device 10. In a specific example, the total length of the first fixing member 110 can be 15cm-25cm, and the total width can be 6cm-10cm, and the mounting portion 113 thereof is provided with a mounting through hole 113a having a substantially trapezoidal structure, so as to facilitate the mounting of the cutting device 10.

[0057] In addition to the fixing assembly 100, the cutting assembly 200 may also be optimized. In some optional embodiments, the cutting assembly 200 includes a cutting knife 210 and a protection block 220. The cutting knife 210 is inserted into the accommodating cavity 130 and connected to the first fixing member 110 and / or the second fixing member 120. The cutting knife 210 protrudes from the accommodating cavity 130. The protection block 220 is arranged outside the accommodating cavity 130 and is spaced apart from the first fixing member 110 and the second fixing member 120. The protection block 220 is connected to the cutting knife 210.

[0058] Specifically, the cutting knife 210 is extended in the accommodating cavity 130 along the Y direction, i.e., the width direction, and the end of the cutting knife 210 extends out of the accommodating cavity 130 for cutting. The protective block 220 is connected to the end of the cutting knife 210, and the protective block 220 can form a barrier to the cutting knife 210 to prevent the operator from contacting the cutting knife 210, thereby improving safety. In addition, a gap is left between the protective block 220 and the first fixing member 110 and the second fixing member 120, for example, the gap can be 1cm-2cm, so as to prevent the operator's fingers from entering the gap and being scratched by the cutting knife 210. Exemplarily, the material of the cutting knife 210 can be high-strength steel, and the material of the protective block 220 can be rubber, plastic, and the like.

[0059] Further, in some embodiments, the protection block 220 is detachably connected to the cutting blade 210. Exemplarily, the protection block 220 can be threadedly connected to the cutting blade 210 to facilitate disassembly and replacement.

[0060] In some optional embodiments, the cutting knife 210 is provided with blades 212 on both sides of the length direction of the first fixing member 110 or the second fixing member 120. By providing blades 212 on both sides of the cutting knife 210, there are two force application directions of pulling back and pushing forward during use, and the cutting operation is more flexible and convenient.

[0061] For example, refer to Figure 4 , the length direction of the first fixing member 110 and the length direction of the second fixing member 120 are the same and are both in the X direction. Figure 5 , the cutting blade 210 is provided with blades 212 on both sides in the X direction, so when the object 20 to be cut needs to be cut, the cutting device 10 can have two force application directions of pulling back and pushing forward during use. Figure 6 , wherein the force direction of pulling backward is shown, at this time, the blade 212 of the cutting knife 210 on the side close to the gripping portion 111 directly contacts the object 20 to be cut and cuts the object 20 to be cut. Similarly, when the force direction of pushing forward is adopted, at this time, the blade 212 of the cutting knife 210 on the side away from the gripping portion 111 directly contacts the object 20 to be cut and cuts the object 20 to be cut.

[0062] In some optional embodiments, both ends of the cutting blade 210 in the width direction of the first fixing member 110 or the second fixing member 120 protrude from the accommodating cavity 130. Figure 4 The length direction of the first fixing member 110 and the width direction of the second fixing member 120 are the same and are both in the Y direction. By controlling both ends of the cutting knife 210 in the Y direction to extend out of the accommodating cavity 130, and both ends are respectively connected to the corresponding protection blocks 220, so that both ends of the cutting knife 210 can be used for cutting operations. Therefore, when one end of the cutting knife 210 is damaged, it can be switched to the other end for cutting, which is more practical and more beautiful in appearance, and has a good application prospect.

[0063] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Those skilled in the art can change, modify, replace and modify the above embodiments within the scope of the present application.
