These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0042] like Figures 1 to 3 As shown, an embodiment of the first aspect of the present invention provides a tool, which includes a tool body 1 and a cutting piece 2. The cutting piece 2 is arranged on the tool body 1 and extends along the length direction of the tool body 1. The cutting piece 2 can be electrically heated and is used to cut materials.

[0043] Among them, the cutting piece 2 is arranged on the blade body 1 and extends along the length direction of the blade body 1, which means that the cutting piece 2 can be connected to the cutting working position of the blade body 1 and is arranged along the length direction of the blade body 1 on part or the entire working length of the blade body 1, so that the cutting piece 2 can be supported by the blade body 1 and cooperate with the blade body 1 to perform cutting operations.

[0044] The cutting piece 2 can be electrically heated, which means that the cutting piece 2 can be heated to a high temperature to form a hot cutting position after being electrically heated, and the cutting piece 2 can perform hot cutting on the material.

[0045] With this arrangement, when the cutter cuts the material, the cutting element 2 is electrically heated and quickly reaches a high temperature. The blade body 1 not only supports the cutting element 2 but also applies force to the cutting element 2, enabling it to cut the material with great force. With the blade body 1 as its support, the cutting element 2 can withstand high pressure, reducing deformation, damage, and displacement of the cutting element 2, ensuring the cutting effect and extending the service life of the cutting element 2. The cutting piece 2 is arranged on the blade body 1, and can combine hot cutting with cutting by the blade body 1. When the cutting piece 2 is hot cutting the material, the blade body 1 is also performing a downward pressing and cutting operation. The cutting piece 2 can effectively improve the flatness of the cut of the material through hot cutting, and because the cutting piece 2 can withstand greater pressure, when the same cutting requirements are met, compared with the hot cutting of the heating wire in the related technology, the tool of this embodiment can reduce the cutting temperature of the cutting piece 2, shorten the heating time and target temperature, effectively reduce energy consumption, and solve the problem in the related technology that the heating wire is soft and easy to deform after heating, the cutting edge of the chopping knife is uneven, and the cutting effect of the two is poor.

[0046] like Figures 1 to 2 As shown, in some embodiments, the cutting element 2 comprises a coating structure, which can be applied to the blade 11 of the blade body 1. The blade 11 is the sharp portion of the blade body 1 used for cutting or chopping, and is the primary working surface of the blade body 1. The coating structure can be a thin layer applied to the surface of the blade 11. The coating structure has a uniform and thin electroplating thickness, and the profile of the electroplated layer can be the same as the profile of the blade 11. The coating structure can maintain good cutting performance on the blade 11. Furthermore, the coating structure shortens the heating time required for electrical power, thereby reducing energy consumption.

[0047] The coating structure may be an electroplating layer or a chemical coating. The electroplating layer may be made of nickel-chromium alloy, iron-chromium-aluminum, molybdenum, copper or tungsten alloy, and the chemical coating may be made of copper.

[0048] Or, as Figure 3 As shown, the cutting element 2 is a wire structure. The blade body 1 is provided with a mounting slot 12, which extends along the length of the blade body 1. The wire structure is partially embedded in the mounting slot 12. That is, in the radial cross-section of the wire structure, part of the wire structure is embedded in the mounting slot 12, while the other part is exposed outside the mounting slot 12. The wire structure exposed outside the mounting slot 12 can perform hot cutting on the material. The wire structure is connected to the mounting slot 12 through an embedded locking mechanism. The mounting slot 12 can lock and limit the wire structure, reducing its displacement and maintaining the positional stability of the wire structure relative to the blade body 1.

[0049] Optionally, the thickness of the blade body 1 can be close to the diameter of the wire structure, and the blade 11 does not need to be provided on the blade body 1. The mounting groove 12 can be directly opened on the edge section of the blade body 1 to allow the wire structure to be embedded.

[0050] Optionally, the thickness of the blade body 1 may also be much larger than the diameter of the wire structure. The blade body 1 may be provided with a blade 11, and the mounting groove 12 may be opened at the tip of the blade 11. The hot cutting of the wire structure can be combined with the cutting of the blade 11 to improve the cutting effect, and can be applicable to blade bodies 1 of various sizes and types.

[0051] like Figures 1 to 3 As shown, in some embodiments, the blade body 1 is a straight blade or a serrated blade, that is, the contour shape of the blade body 1 in its own length direction can be a straight line or a zigzag wavy line, and the cutting piece 2 can be stably arranged on the blade body 1.

[0052] For example, when the cutting piece 2 is a coated structure and the blade body 1 is a serrated blade, after the coating structure is coated on the blade body 1, the contour shape of the combination of the two can still be a serrated shape, which can increase the contact points between the coating structure and the material, provide more cutting force during cutting, and help reduce the resistance during cutting, reduce the required thrust, and improve cutting efficiency.

[0053] The cutting piece 2 is a wire structure. When the blade body 1 is a serrated blade, the wire structure can also be bent into a serrated wavy line that matches the blade body 1. The wire structure is embedded in the blade body 1 through the mounting groove 12. The combination of the two can still be serrated and also has the advantages of the above-mentioned serrated blade.

[0054] like Figures 1 to 3 As shown, in some embodiments, the cutting edge angle β of the blade 11 ranges from 15° to 60°, that is, the blade body 1 has two cut surfaces, and the intersection of the extended lines of the two cut surfaces can form the blade 11. The cutting edge angle of the blade 11 is the angle between the two cut surfaces, that is, Figure 1 β angle shown in . The edge angle of the blade 11 can be selected to be 15°, 30°, 45° or 60°. When the edge angle β of the blade 11 is 15°, the blade 11 of the tool is sharp, the size of the cutting piece 2 is also smaller, the tool can provide a fine cutting effect, and is suitable for high-sharpness cutting tasks. When the edge angle β of the blade 11 is 30°, it can take into account the sharpness and structural retention of the blade 11, and while providing a fine cutting effect, it can also withstand a certain impact force and reduce deformation and damage. When the edge angle β of the blade 11 is 45°, the sharpness of the blade 11 will be weakened, but the impact resistance will be enhanced, the structural retention is better, and it is also convenient to provide a layout position for the cutting piece 2. When the edge angle β of the blade 11 is 60°, the sharpness of the blade 11 gradually decreases, the structural retention is better, and the impact resistance is stronger.

[0055] In some embodiments, the blade body 1 is made of an insulating material, meaning that the entire blade body 1 can be made of an insulating material. Alternatively, at least the portion of the blade body 1 that contacts the cutting piece 2 can be made of an insulating material, meaning that the blade body 1 can be partially made of an insulating material. This allows the blade body 1 and the cutting piece 2 to be insulated, thereby minimizing the effects of electrical heating on the cutting piece 2. For example, the blade body 1 can include a blade body and an insulating layer, with the insulating layer disposed between the blade body and the cutting piece 2. The blade body can be made of metal or an insulating material, and the insulating layer can be made of an insulating material.

[0056] In this embodiment, the insulating material may be a non-metallic material, such as plastic or ceramic.

[0057] like Figures 1 to 3 As shown, in some embodiments, a terminal is provided on the blade body 1, and the terminal can be electrically connected to a power supply. The terminal is provided at a position of the blade body 1 close to the cutting piece 2, and the cutting piece 2 can be selectively electrically connected or disconnected with the terminal, that is, the terminal can serve as a connection position for electrically connecting the cutting piece 2 to the power supply. When the cutting piece 2 is in contact with the terminal, it can be electrically connected to the power supply and heated. When the cutting piece 2 is not in contact with the terminal, the cutting piece 2 is disconnected from the power supply and no longer heated, which facilitates flexible control of the power on and off of the cutting piece 2 and ensures the accuracy of the power on and off switching.

[0058] In this embodiment, the terminal can be rotatably or slidably connected to the blade body 1, so that the terminal can be moved closer to or farther away from the cutting piece 2, thereby achieving electrical connection or disconnection between the terminal and the cutting piece 2. The terminal can be a sheet-like structure or a columnar structure, and the cutting piece 2 can also be provided with grooves or protrusions to facilitate insertion of the terminal and increase the stability of the connection between the terminal and the cutting piece 2.

[0059] like Figures 1 to 2 As shown, in some embodiments, the tool further includes a shell 3, which is connected to the blade body 1. The shell 3 can be set to cover the cutting piece 2, or the shell 3 can cover the entire blade body 1, that is, the shell 3 can be set on the blade body 1 for covering and protection. The shell 3 can be set only at the cutting piece 2, or it can cover the entire blade body 1, and it can at least block and protect the cutting piece 2.

[0060] like Figures 1 to 2 As shown, in some embodiments, the tool also includes an ejector, the blade body 1 is slidably connected to the shell 3, and the ejector is arranged between the blade body 1 and the shell 3. The ejector can eject the blade body 1 out of the shell 3 so that the blade body 1 and the cutting piece 2 can extend and move away from the shell 3 to perform melting and pressurized cutting operations on the material.

[0061] In this embodiment, the ejector can be, but is not limited to, an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, which can perform telescopic movement to push the blade body 1 to move relative to the housing 3.

[0062] like Figures 4 and 5 As shown, in some embodiments, the shell 3 includes two shielding structures 31, which are arranged on both sides of the blade body 1. The two shielding structures 31 are interlocked with each other to cover the cutting piece 2, that is, the shell 3 can be designed as a split structure, which is arranged on both sides of the blade body 1 to cover the blade body 1, and can better adapt to the situation where the blade body 1 is longer. The two shielding structures 31 can be extended along the length direction of the blade body 1 to cover the blade body 1 as a whole.

[0063] like Figures 4 and 5 As shown, point a shown in the figure is a schematic diagram of the rotational connection position of the first end of the first connecting member 313 and the second end of the baffle 312, point b shown in the figure is a schematic diagram of the rotational connection position of the second end of the second connecting member 314 and the baffle 312, point c shown in the figure is a schematic diagram of the rotational connection position of the first end of the second connecting member 314 and the blade body 1, and point d shown in the figure is a schematic diagram of the position of the second end of the first connecting member 313. The second end of the first connecting member 313 can slide in the sliding groove of the bracket 311, and the second end of the first connecting member 313 can be rotatably connected to the second end of the telescopic rod, or the second end of the first connecting member 313 can abut or be fixedly connected to the end of the elastic member.

[0064] Specifically, the shielding structure 31 includes a bracket 311, a baffle 312, a first connecting member 313, a second connecting member 314, and an opening and closing drive member. The bracket 311 is disposed on the side of the blade body 1 and is provided with a slide groove. The blade body 1 can be slidably connected to the housing 3 through the slide groove on the bracket 311. The bracket 311 can support the baffle 312, the first connecting member 313, and the second connecting member 314. The bracket 311 is disposed on the blade body 1 near the cutting piece 2, and can also cover the entire blade body 1. The ejector can be disposed between the bracket 311 and the blade body 1.

[0065] The baffle 312 has a first end and a second end that are relatively set. The first end of the baffle 312 can be set at the position of the cutting piece 2, and the second end of the baffle 312 is set away from the position of the cutting piece 2. The baffles 312 of the two shielding structures 31 can be close to each other and buckled together to cover the cutting piece 2 as a whole. The baffles 312 of the two shielding structures 31 can be spread away from each other to expose the cutting piece 2.

[0066] The first connecting member 313 has a first end and a second end that are relatively arranged. The first end of the first connecting member 313 is rotatably connected to the second end of the baffle 312. The first connecting member 313 can be, but is not limited to, a rod-shaped or plate-shaped structure, and can rotatably mount the baffle 312.

[0067] The second connecting member 314 has a first end and a second end that are arranged opposite each other. The first end of the second connecting member 314 is rotatably connected to the blade body 1, and the second end of the second connecting member 314 is rotatably connected to the baffle 312. The second connecting member 314 can be, but is not limited to, a rod-shaped or plate-shaped structure, and can be rotatably mounted and supported between the blade body 1 and the baffle 312. There is a gap between the second end of the second connecting member 314 and the second end of the baffle 312, that is, the second end of the second connecting member 314 can be supported at a non-end position of the baffle 312. The first connecting member 313, the second connecting member 314, and the baffle 312 can form a connecting rod structure. The second connecting member 314 can rotatably mount the baffle 312 and can adaptively rotate according to the rotational position of the first connecting member 313 and the baffle 312, so that the baffle 312 can rotate flexibly and smoothly with the first connecting member 313 and has multi-point support.

[0068] The opening and closing drive member has a first end and a second end that are relatively set. The first end of the opening and closing drive member can be set on the blade body 1, with the blade body 1 as the mounting support, or it can also be set on the bracket 311, with the bracket 311 as the mounting support. The second end of the opening and closing drive member is set in the slide groove, and the second end of the opening and closing drive member is connected to one end of the first connecting member 313, which is used to drive the second connecting member 314 and the baffle 312 to open and close, so that the cutting piece 2 is exposed or the cutting piece 2 is shielded and protected. The opening and closing drive member can be set according to the needs of use, and can provide driving force for the opening and closing of the second connecting member 314 and the baffle 312.

[0069] Optionally, the opening and closing drive member can be a telescopic rod, and the shielding structure 31 includes a bracket 311, a baffle 312, a first connecting member 313, a second connecting member 314 and a telescopic rod, the telescopic rod having a first end and a second end relatively arranged, the first end of the telescopic rod being rotatably connected to the knife body 1, the second end of the telescopic rod being rotatably connected to the second end of the first connecting member 313, and the second end of the telescopic rod being slidably connected to the slide groove, and the extension of the telescopic rod can drive the baffle 312 to rotate away from the position of the cutting piece 2 through the first connecting member 313 and the second connecting member 314 to expose the cutting piece 2.

[0070] That is, the telescopic rod can serve as a driving part for opening or closing the baffle 312. When the cutting piece 2 needs to extend out of the shell 3, under the action of external forces such as the ejector or manual push, or under the force of the driving parts such as the motor, cylinder or hydraulic cylinder built into the telescopic rod, the telescopic rod can extend along its own axis, and the cutting piece 2 moves outward relative to the second end of the first connecting piece 313. The second end of the first connecting piece 313 slides relative to the slide groove, and the first end of the first connecting piece 313 rotates and pulls the baffle 312 to rotate around the first end of the second connecting piece 314. The baffle 312 rotates away from the position of the cutting piece 2. When the telescopic rod is extended to the limit position, the second end of the first connecting piece 313 can continue to slide relative to the slide groove and move with the cutter body 1. The baffle 312 rotates away from the position of the cutting piece 2 to expose the cutting piece 2, and the cutting piece 2 can cut the material together with the cutting piece 2. After the cutting is completed, the telescopic rod can be shortened along its own axis under the action of external force or the driving action of the telescopic rod itself, and the cutting piece 2 moves inward relative to the second end of the first connecting piece 313. The second end of the first connecting piece 313 slides in the opposite direction relative to the slide groove. The first end of the first connecting piece 313 rotates and pulls the baffle 312 to rotate around the first end of the second connecting piece 314. The baffle 312 can be rotated close to the cutting piece 2 to block and protect the cutting piece 2.

[0071] Optionally, the opening and closing driving member can be an elastic member, and the shielding structure 31 includes a bracket 311, a baffle 312, a first connecting member 313, a second connecting member 314 and an elastic member, the elastic member is arranged in the slide groove, the second end of the first connecting member 313 is slidably connected to the slide groove, and the elastic member can abut the second end of the first connecting member 313, and a stop block is provided on the knife body 1, and the stop block is slidably connected to the slide groove. The force of the stop block on the second end of the first connecting member 313 can be greater than the force of the elastic member on the second end of the first connecting member 313, so that the knife body 1 can push the second end of the first connecting member 313 through the stop block to overcome the force of the elastic member to slide, and the first connecting member 313 can drive the second connecting member 314 and the baffle 312 to rotate away from the position of the cutting piece 2 to expose the cutting piece 2.

[0072] As another optional structure of the shielding structure 31, an elastic member can be arranged in the slide groove to abut against the second end of the first connecting member 313, so that the baffle 312 maintains a shielding and protective state for the cutting piece 2. When the cutting piece 2 needs to extend out of the shell 3, under the action of an external force such as an ejector or manual push, the blade body 1 moves outward relative to the bracket 311 of the shell 3. After the stopper on the blade body 1 moves to the second end position of the first connecting member 313, it continues to apply force to the second end of the first connecting member 313, so that the second end of the first connecting member 313 can overcome the elastic force of the elastic member and slide in the slide groove, thereby causing the first connecting member 313 to rotate and drive the baffle 312 and the second connecting member 314 to rotate in conjunction. The second connecting member 314 and the baffle 312 rotate away from the cutting piece 2 to expose the cutting piece 2, and the blade body 1 and the cutting piece 2 can cut the material together.

[0073] The first end of the first connector 313 and the second end of the baffle 312, the first end of the second connector 314 and the blade body 1, and the second end of the second connector 314 and the baffle 312 can all be rotatably connected via fisheye joints. This rotatable connection is stable and flexible, can withstand high stress, and is convenient to connect. The elastic member can be, but is not limited to, a spring or an elastic tube.

[0074] The cutting device provided by the embodiment of the second aspect of the present invention includes a cutting drive and a tool in any of the above embodiments. The cutting drive is connected to the cutter body 1 in a transmission manner. The cutting drive can drive the cutter body 1 and the cutting piece 2 to move, that is, the cutter can be used alone or driven by the cutting drive. The cutting drive can drive the cutter to reciprocate so that the cutter body 1 and the cutting piece 2 can cut the material quickly and efficiently, reducing the intensity of manual labor, and facilitating the uniformity and uniformity of the tool driving force, thereby reducing the influence of excessive or insufficient force on the cutting edge accuracy.

[0075] Among them, the cutting drive component can be a linear motion module, and its driving method can be but not limited to a combined structure of a motor and a screw nut, a cylinder or a hydraulic cylinder, which can drive the tool to move stably to achieve cutting.

[0076] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented.
