Description

Technical Field

[0001] This invention relates to the field of cutting tool technology, specifically to a cutting tool. Background Technology

[0002] Cutting tools are tools used for cutting processes in mechanical manufacturing. The vast majority of tools are machine-made, but some are hand-operated. Since tools used in mechanical manufacturing are primarily for cutting metal materials, the term "tool" is generally understood to refer to metal cutting tools. Tools used for cutting wood are called woodworking tools.

[0003] In existing technologies, some cutting tools, after prolonged machining, may experience slippage and detachment of the cutting head due to vibration or external environmental influences. This results in a loose cutting head, affecting the tool's ability to machine parts and the efficiency of part machining. In severe cases, it can damage the cutting head, impacting machining efficiency and cutting head utilization, thus wasting resources. Furthermore, while some existing cutting heads are tightly connected to the tool body, separating them after damage is cumbersome. Replacing both the cutting head and the tool body is costly and wasteful of resources.

[0004] Therefore, a cutting tool is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting tool to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting tool, including a tool body, wherein a cutting head is threadedly connected to the lower outer surface of the tool body near the middle position, and a fixing mechanism is provided near the middle position at the connection between the tool body and the cutting head, the fixing mechanism including a first fixing mechanism and a second fixing mechanism, for connecting and fixing the tool body and the cutting head at the middle.

[0007] In existing technologies, most mechanical cutting tools, after prolonged machining, will experience slippage and detachment of the cutting head due to vibration or external environmental influences. This results in a loose cutting head, affecting the tool's ability to process parts and its efficiency. In severe cases, it can damage the cutting head, further reducing machining efficiency and cutting head utilization, thus wasting resources. This invention addresses this issue by incorporating a fixing mechanism to ensure a tight connection between the cutting head and the tool body. This prevents the slippage and detachment of the cutting head caused by vibration or external environmental influences after prolonged machining, thus avoiding the problems of reduced machining efficiency and efficiency. Furthermore, the separation of the cutting head from the tool body is simple after damage, eliminating the need to replace both the cutting head and the tool body, resulting in low replacement costs and minimizing resource waste. This improves overall practicality and versatility.

[0008] Preferably, the first fixing mechanism includes a first mounting groove, an electromagnet, a first spring, a first magnet, a first connecting plate, and a first connecting groove. The first mounting groove is provided at the connection between the blade body and the blade head near the upper two sides. An electromagnet is fixedly installed on the inner surface of one side of the first mounting groove near the middle position. A first spring is symmetrically fixedly installed on the inner surface of one side of the first mounting groove near the electromagnet on both sides. A first magnet is fixedly installed at one end of the first spring. A first connecting plate is fixedly installed on the outer surface of the right side of the first magnet. The first connecting groove is provided at the connection between the blade head and the blade body near the upper two sides. A power mechanism is provided inside the blade body near the upper end of the first mounting groove.

[0009] During operation, after the cutter body and cutter head are installed and work is required, the power mechanism provides power to the electromagnet. When the electromagnet is energized, it generates magnetic force. Because the magnetic properties of the adjacent end faces of the electromagnet and the first magnet are opposite, a repulsive force is generated between the electromagnet and the first magnet when the electromagnet is energized. This repulsive force overcomes the elastic force of the first spring, causing the first magnet to move the first connecting plate towards the first connecting groove until the right outer surface of the first connecting plate contacts the left outer surface of the first connecting groove, completing the fixing process. After the cutter body and cutter head are installed and work is stopped, the power mechanism stops supplying power to the electromagnet, the electromagnet's magnetic force disappears, the repulsive force between the electromagnet and the first magnet disappears, and the elastic force of the first spring returning to its elastic deformation moves the first connecting plate away from the first connecting groove. The direction is moved until the first spring returns to its original position, and the first connecting plate moves into the first mounting slot. This simplifies the separation of the cutter head from the cutter body after damage, thereby improving the tightness of the connection between the cutter head and the cutter body. This avoids the common problem of cutter heads slipping and falling off due to vibration or external environmental factors after prolonged machining, which can affect the machining efficiency of parts. It also prevents damage to the cutter head, thus avoiding wasted resources. Furthermore, the simple separation of the cutter head from the cutter body after damage eliminates the need to replace both, resulting in low replacement costs and resource conservation. This improves overall practicality and versatility.

[0010] Preferably, a uniformly distributed connecting block is fixedly installed on the right outer surface of the first connecting plate, a uniformly distributed second connecting groove is opened on one inner surface of the first connecting groove, and a first airbag is fixedly installed on both inner surfaces of the second connecting groove and one inner surface of the second connecting groove. The first airbag is filled with a liquid that solidifies when energized.

[0011] During operation, this invention incorporates a connecting block. When the right outer surface of the first connecting plate contacts the left outer surface of the first connecting groove, the connecting block compresses the first airbag, causing it to fully enter the second connecting groove. The liquid inside the first airbag hardens due to electrical current, resulting in a tighter connection between the connecting block and the second connecting groove. After the blade body and blade head are installed and operation stops, the power mechanism ceases to supply power to the liquid inside the first airbag. As the first connecting plate moves away from the first connecting groove, the connecting block easily separates from the second connecting groove, thereby increasing the tightness of the connection between the blade body and blade head, further improving the working effect of the first fixing mechanism, and enhancing overall practicality.

[0012] Preferably, the first airbag contains an electrorheological fluid that solidifies when energized.

[0013] During operation, this invention uses an electrorheological fluid, which is a liquid that solidifies upon energization, to fill the first airbag. This electrorheological fluid is a new material whose hardness can be adjusted and which can instantly change from a liquid phase to a solid phase. Its shear strength can be continuously adjusted, respond quickly, and change reversibly under the action of an electric field, ensuring the working effect of the first fixing mechanism and improving the overall practicality.

[0014] Preferably, the outer surface of the connecting block is provided with uniformly distributed third connecting grooves.

[0015] During operation, this invention, by setting a third connecting groove, allows the first airbag to enter the second connecting groove as the first connecting plate moves towards the first connecting groove and the connecting block squeezes the first airbag to fully enter the second connecting groove. The squeezing force causes the first airbag to enter the third connecting groove. When the liquid inside the first airbag is electrified and hardens, the tightness of the connection between the connecting block and the second connecting groove is further improved, thereby further improving the working effect of the first fixing mechanism and improving the overall practicality.

[0016] Preferably, the first spring is a stainless steel component that cannot be attracted by an electromagnet when energized.

[0017] During operation, this invention uses a stainless steel component as the first spring, which cannot be attracted by an electromagnet when energized. This avoids the problem that the magnetic force generated by the electromagnet when energized affects the normal operation of the first spring, thus improving the overall practicality.

[0018] Preferably, the power mechanism includes a magnetic ring, a third mounting slot, a magnetic block, a rotating rod, a second magnet, a commutator, a capacitor, and a magnetic induction coil. A magnetic ring is fixedly connected to the outer surface of the cutter body near its upper end. A third mounting slot is formed on the inner surface of the cutter body near the upper end of the first mounting slot. A rotating rod is rotatably connected to the inner top surface of the third mounting slot near its middle position. A magnetic block is attached to the upper outer surface of the rotating rod. A magnetic induction coil is fixedly installed on the outer surface of the rotating rod near its lower end. Second magnets are fixedly installed on both sides of the inner surface of the third mounting slot near the magnetic induction coil. The magnetic induction coil works in conjunction with two sets of second magnets. A commutator is fixedly installed on the outer surface of the rotating rod near the lower end of the magnetic induction coil. The commutator is electrically connected to the magnetic induction coil. A capacitor is fixedly installed on the outer surface of the rotating rod near the lower end of the commutator.

[0019] During operation, this invention employs a power mechanism. As the blade rotates, the magnetic force between the magnetic ring and the magnetic block causes the magnetic ring to rotate, which in turn drives the rotating rod. The rotating rod then drives the magnetic induction coil to cut the magnetic field lines between the two second magnets, thereby generating an induced current inside the magnetic induction coil. This induced current is transmitted to a diode via a commutator, where it is converted into electricity and stored in a capacitor to provide power for subsequent operations. When the first fixing mechanism is in operation, the capacitor transmits the current to the electromagnet and the electrorheological fluid via wires, providing them with a power source, thus improving the overall practicality.

[0020] Preferably, the second fixing mechanism includes a second mounting groove, a second spring, a second airbag, a second connecting plate, a fourth connecting groove, and a heat-conducting iron. The second mounting groove is provided on both sides near the lower end of the connection between the blade body and the blade head. A second spring is fixedly installed on the inner surface of one side of the second mounting groove near the middle position. A second airbag is fixedly installed on the inner surface of one side of the second mounting groove near the inner side of the second spring. A second connecting plate is fixedly connected to one end of both the second airbag and the second spring. A fourth connecting groove is provided on both sides near the lower end of the connection between the blade head and the blade body. A heat-conducting iron is fixedly installed inside the blade body near the end of the second airbag. One end of the heat-conducting iron is located near the blade head.

[0021] During operation, this invention utilizes a second mounting groove. Since higher workpiece material strength and hardness result in greater energy consumption, more cutting heat, and higher cutting temperatures during cutting, when the workpiece material has high strength, the heat generated during cutting rises. Because the second airbag contains easily expandable gases, such as carbon dioxide, heat is transferred to the second airbag via a heat-conducting iron. The gas inside the second airbag expands, and the expansion force overcomes the elastic force of the second spring, pushing the second connecting plate towards the inner surface of the fourth connecting groove until the second connecting plate is in complete contact with the fourth connecting groove, completing the fixing process. After the tool body and tool head are installed and operation stops, the temperature decreases, the gas inside the second airbag returns to its original state, and the elastic force of the second spring, restoring its elastic deformation, drives the second connecting plate away from the fourth connecting groove. The direction is moved until the second spring returns to its original position, and the second connecting plate moves into the fourth connecting groove. This simplifies the separation of the cutter head from the cutter body after damage, thereby improving the tightness of the connection between the cutter head and the cutter body through the second fixing mechanism. This avoids the common problem of cutter heads slipping and falling off due to vibration or external environmental factors after prolonged machining, which can affect the machining efficiency of parts. It also prevents damage to the cutter head, thus avoiding wasted resources. Furthermore, the simple separation of the cutter head from the cutter body after damage eliminates the need to replace both, resulting in low replacement costs and resource waste. This improves overall practicality and versatility.

[0022] Preferably, a telescopic sleeve is fixedly installed on one side of the inner surface of the second mounting groove, near the inner side of the second spring and the outer side of the second airbag, and one end of the telescopic sleeve is fixedly connected to a second connecting plate.

[0023] During operation, the present invention provides a telescopic sleeve that is fixedly installed on the inner surface of one side of the second mounting groove, close to the inner side of the second spring and the outer side of the second airbag. This avoids the problem of deformation of the second spring when the second airbag expands, thus improving the overall practicality.

[0024] Preferably, rubber pads are fixedly installed on both the bottom and top surfaces of the fourth connecting groove.

[0025] During operation, the present invention further improves the tightness of the connection between the second connecting plate and the fourth connecting groove by fixing rubber pads on both the bottom and top surfaces of the fourth connecting groove, thereby further ensuring the working effect of the second fixing mechanism and improving the overall practicality.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. This invention, by setting up a fixing mechanism, further ensures the tightness of the connection between the cutter body and the cutter head. This avoids the problem of the cutter head slipping and falling off due to vibration or external environmental influences after prolonged processing, which can lead to a loose cutter head and affect the processing efficiency of the parts. It also prevents damage to the cutter head, thus avoiding the waste of resources. Furthermore, in the event of cutter head damage, the separation between the cutter head and the cutter body is simple, eliminating the need to replace both the cutter head and the cutter body, resulting in low replacement costs and no waste of resources. This improves the overall practicality and versatility. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Please see Figures 1 to 7 This invention provides a cutting tool technical solution:

[0043] A cutting tool, such as Figures 1 to 3 As shown, it includes a blade body 1, and a blade head 2 is threadedly connected to the lower outer surface of the blade body 1 near the middle position. A fixing mechanism is provided near the middle position at the connection between the blade body 1 and the blade head 2. The fixing mechanism includes a first fixing mechanism and a second fixing mechanism, which are used to fix the connection between the blade body 1 and the blade head 2.

[0044] In existing technologies, most mechanical cutting tools, after prolonged machining, will experience slippage and detachment of the cutting head 2 due to vibration or external environmental influences. This results in a loose cutting head 2, affecting the tool's ability to process parts and its efficiency. In severe cases, it can damage the cutting head 2, further impacting machining efficiency and its utilization rate, thus wasting resources. This invention addresses this issue by incorporating a fixing mechanism to ensure a tight connection between the cutting body 1 and the cutting head 2. This prevents the slippage and detachment of the cutting head 2 caused by vibration or external environmental influences after prolonged machining, thus avoiding the problems of reduced machining efficiency and efficiency. Furthermore, it avoids damage to the cutting head 2, minimizing resource waste. Additionally, if the cutting head 2 is damaged, separation from the cutting body 1 is simple, eliminating the need to replace both the cutting head 2 and the cutting body 1, reducing replacement costs, and preventing resource waste. This improves overall practicality and versatility.

[0045] As one embodiment of the present invention, such as Figures 1 to 3 As shown, the first fixing mechanism includes a first mounting groove 31, an electromagnet 32, a first spring 33, a first magnet 34, a first connecting plate 35, and a first connecting groove 36. The first mounting groove 31 is provided near the upper two sides of the connection between the blade body 1 and the blade head 2. An electromagnet 32 ​​is fixedly installed on one inner surface of the first mounting groove 31 near the middle position. The first spring 33 is symmetrically fixedly installed on one inner surface of the first mounting groove 31 near the two sides of the electromagnet 32. A first magnet 34 is fixedly installed at one end of the first spring 33. A first connecting plate 35 is fixedly installed on the right outer surface of the first magnet 34. The first connecting groove 36 is provided near the upper two sides of the connection between the blade head 2 and the blade body 1. A power mechanism is provided inside the blade body 1 near the upper end of the first mounting groove 31.

[0046] During operation, when the blade body 1 and blade head 2 are installed and ready to work, the power mechanism provides power to the electromagnet 32. When the electromagnet 32 ​​is energized, it generates magnetic force. Since the magnetic properties of the adjacent end faces of the electromagnet 32 ​​and the first magnet 34 are opposite, a repulsive force is generated between the electromagnet 32 ​​and the first magnet 34 due to the repulsion of like poles. This repulsive force overcomes the elastic force of the first spring 33, causing the first magnet 34 to move the first connecting plate 35 towards the first connecting groove 36 until the right outer surface of the first connecting plate 35 contacts the left outer surface of the first connecting groove 36, completing the fixing process. When the blade body 1 and blade head 2 are installed and work is stopped, the power mechanism stops providing power to the electromagnet 32, the magnetic force of the electromagnet 32 ​​disappears, the repulsive force between the electromagnet 32 ​​and the first magnet 34 disappears, and the elastic force of the first spring 33, restoring its elastic deformation, moves the first connecting plate 35 towards the first connecting groove 36. 5. Move away from the first connecting groove 36 until the first spring 33 returns to its original position. The first connecting plate 35 moves into the first mounting groove 31. After the cutter head 2 is damaged, the separation operation between the cutter head 2 and the cutter body 1 is simple. This improves the fixing mechanism and further ensures the tightness of the connection between the cutter body 1 and the cutter head 2. It avoids the problem that most mechanical tools will slip and fall off due to vibration or external environmental influences after long processing time, resulting in the cutter head 2 not being secure. This will affect the tool's processing of parts and the efficiency of part processing. At the same time, it will not cause damage to the cutter head 2, affecting the efficiency of part processing and the utilization rate of the cutter head 2, thus wasting resources. In addition, after the cutter head 2 is damaged, the separation operation between the cutter head 2 and the cutter body 1 is simple. It is not necessary to replace both the cutter head 2 and the cutter body 1. The replacement cost is low and there is no waste of resources. It improves the overall practicality and versatility.

[0047] As one embodiment of the present invention, such as Figure 5 As shown, a uniformly distributed connecting block 37 is fixedly installed on the right outer surface of the first connecting plate 35, and a uniformly distributed second connecting groove 38 is opened on one inner surface of the first connecting groove 36. A first airbag 39 is fixedly installed on the inner surfaces of both ends and one inner surface of the second connecting groove 38. The first airbag 39 is filled with a liquid that solidifies when energized.

[0048] During operation, the present invention, by setting a connecting block 37, when the right outer surface of the first connecting plate 35 contacts the left outer surface of the first connecting groove 36, the connecting block 37 squeezes the first airbag 39 completely into the second connecting groove 38. The liquid inside the first airbag 39 hardens due to electricity, making the connection between the connecting block 37 and the second connecting groove 38 tighter. After the blade body 1 and the blade head 2 are installed and the operation stops, the power mechanism stops providing power to the liquid inside the first airbag 39. As the first connecting plate 35 moves away from the first connecting groove 36, the connecting block 37 and the second connecting groove 38 separate easily, thereby improving the tightness of the connection between the blade body 1 and the blade head 2, further improving the working effect of the first fixing mechanism, and improving the overall practicality.

[0049] As one embodiment of the present invention, such as Figure 5 As shown, the first airbag 39 contains an electrorheological fluid that solidifies when energized.

[0050] During operation, the present invention uses an electrorheological fluid, which is a liquid that solidifies upon energization, inside the first airbag 39. The electrorheological fluid is a new material whose hardness can be adjusted and which can instantly change from a liquid phase to a solid phase. Its shear strength can be continuously adjusted, respond quickly, and reversed under the action of an electric field, ensuring the working effect of the first fixing mechanism and improving the overall practicality.

[0051] As one embodiment of the present invention, such as Figure 3 As shown, the outer surface of the connecting block 37 is provided with uniformly distributed third connecting grooves 30.

[0052] During operation, the present invention, by setting a third connecting groove 30, allows the first airbag 39 to fully enter the second connecting groove 38 as the first connecting plate 35 moves towards the first connecting groove 36 and the connecting block 37 squeezes it. The squeezing force causes the first airbag 39 to enter the third connecting groove 30. When the liquid inside the first airbag 39 is electrified and hardens, the tightness of the connection between the connecting block 37 and the second connecting groove 38 is further improved, thereby further improving the working effect of the first fixing mechanism and improving the overall practicality.

[0053] As one embodiment of the present invention, such as Figure 3 As shown, the first spring 33 is a stainless steel component and cannot be attracted by the electromagnet 32 ​​after it is energized.

[0054] During operation, this invention sets the first spring 33 to be a stainless steel component, which cannot be attracted by the electromagnet 32 ​​after it is energized. This avoids the problem that the magnetic force generated by the electromagnet 32 ​​after it is energized will affect the normal operation of the first spring 33, thus improving the overall practicality.

[0055] As one embodiment of the present invention, such as Figure 7 As shown, the power mechanism includes a magnetic ring 310, a third mounting groove 311, a magnetic block 312, a rotating rod 313, a second magnet 314, a commutator 315, a capacitor 316, and a magnetic induction coil 317. A magnetic ring 310 is fixedly connected to the outer surface of the blade body 1 near its upper end. A third mounting groove 311 is formed inside the blade body 1 near the upper end of the first mounting groove 311. A rotating rod 313 is rotatably connected to the inner top surface of the third mounting groove 311 near its center. A magnetic block 312 is located on the upper outer surface of the rotating rod 313. A magnetic induction coil 317 is fixedly installed on the outer surface of the third mounting groove 311 near the lower end. A second magnet 314 is fixedly installed on both sides of the inner surface of the third mounting groove 311 near the magnetic induction coil 317. The magnetic induction coil 317 is used in conjunction with the two sets of second magnets 314. A commutator 315 is fixedly installed on the outer surface of the rotating rod 313 near the lower end of the magnetic induction coil 317. The commutator 315 is electrically connected to the magnetic induction coil 317. A capacitor 316 is fixedly installed on the outer surface of the rotating rod 313 near the lower end of the commutator 315.

[0056] During operation, this invention employs a power mechanism. When the blade 1 rotates, the magnetic force between the magnetic ring 310 and the magnetic block 312 causes the magnetic ring 310 to rotate, which in turn drives the rotating rod 313 to rotate. The rotating rod 313 then drives the magnetic induction coil 317 to cut the magnetic field lines between the two second magnets 314, thereby generating an induced current inside the magnetic induction coil 317. This induced current is transmitted to the diode through the commutator 315, where it is converted into electricity and stored in the capacitor 316 to provide power for subsequent operations. When the first fixing mechanism is in operation, the capacitor 316 transmits the current to the electromagnet 32 ​​and the electrorheological fluid through wires, providing them with a power source, thus improving the overall practicality.

[0057] As one embodiment of the present invention, such as Figure 6 As shown, the second fixing mechanism includes a second mounting groove 41, a second spring 42, a second airbag 43, a second connecting plate 44, a fourth connecting groove 45, and a heat-conducting iron 48. The second mounting groove 41 is provided near the lower end of the connection between the blade body 1 and the blade head 2. The second spring 42 is fixedly installed on the inner surface of one side of the second mounting groove 41 near the middle position. The second airbag 43 is fixedly installed on the inner surface of one side of the second mounting groove 41 near the inner side of the second spring 42. The second connecting plate 44 is fixedly connected to one end of both the second airbag 43 and the second spring 42. The fourth connecting groove 45 is provided near the lower end of the connection between the blade head 2 and the blade body 1. The heat-conducting iron 48 is fixedly installed inside the blade body 1 near the end of the second airbag 43. One end of the heat-conducting iron 48 is located near the blade head 2.

[0058] During operation, this invention utilizes a second mounting groove 41. Because higher workpiece material strength and hardness result in greater energy consumption and heat generation during cutting, leading to higher cutting temperatures, when the workpiece material has high strength, the second airbag 43, containing easily expandable gases such as carbon dioxide, is heated. Heat is transferred to the second airbag 43 via the heat-conducting iron 48, causing the gas inside to expand. This expansion force overcomes the elasticity of the second spring 42, pushing the second connecting plate 44 towards the inner surface of the fourth connecting groove 45 until it fully contacts the fourth connecting groove 45, completing the fixing process. After the tool body 1 and tool head 2 are installed and operation stops, the temperature decreases, the gas inside the second airbag 43 returns to its original state, and the elastic force of the second spring 42, restoring its elastic deformation, drives the second connecting plate 44 away from the fourth connecting groove 45 until the second spring 42 returns to its original position. When the connecting plate 44 moves into the fourth connecting groove 45, the separation operation between the cutter head 2 and the cutter body 1 is simple after the cutter head 2 is damaged. The heat generated at the cutter head 2 is transferred to the second air bag 43 for dissipation through the heat-conducting iron 48 to a certain extent, improving the heat dissipation effect of the cutter head 2 during operation. The second fixing mechanism further ensures the tightness of the connection between the cutter body 1 and the cutter head 2, avoiding the problem that most mechanical tools will slip and fall off due to vibration or external environmental influences after long processing time, resulting in the cutter head 2 not being secure, which will affect the tool's processing of parts and the efficiency of part processing. At the same time, it will not cause damage to the cutter head 2, affecting the efficiency of part processing and the utilization rate of the cutter head 2, thus wasting resources. In addition, after the cutter head 2 is damaged, the separation operation between the cutter head 2 and the cutter body 1 is simple, and it is not necessary to replace both the cutter head 2 and the cutter body 1. The replacement cost is low, and there is no waste of resources, improving the overall practicality and versatility.

[0059] As one embodiment of the present invention, such as Figure 6 As shown, a telescopic sleeve 47 is fixedly installed on one side of the inner surface of the second mounting groove 41 near the inner side of the second spring 42 and the outer side of the second airbag 43. One end of the telescopic sleeve 47 is fixedly connected to a second connecting plate 44.

[0060] During operation, the present invention provides a telescopic sleeve 47 that is fixedly installed on the inner surface of one side of the second mounting groove 41 near the inner side of the second spring 42 and the outer side of the second airbag 43. This avoids the problem of deformation of the second spring 42 when the second airbag 43 expands, thus improving the overall practicality.

[0061] As one embodiment of the present invention, such as Figure 6 As shown, rubber pads 46 are fixedly installed on both the bottom and top surfaces of the fourth connecting groove 45.

[0062] During operation, the present invention further improves the tightness of the connection between the second connecting plate 44 and the fourth connecting groove 45 by fixing rubber pads 46 on both the bottom and top surfaces of the fourth connecting groove 45, thereby further ensuring the working effect of the second fixing mechanism and improving the overall practicality.

[0063] Working Principle: When the blade body 1 and blade head 2 are installed and ready for operation, the power mechanism provides power to the electromagnet 32. When the electromagnet 32 ​​is energized, it generates magnetic force. Since the magnetic properties of the adjacent end faces of the electromagnet 32 ​​and the first magnet 34 are opposite, a repulsive force is generated between the electromagnet 32 ​​and the first magnet 34 due to the repulsion of like poles. This repulsive force overcomes the elastic force of the first spring 33, causing the first magnet 34 to move the first connecting plate 35 towards the first connecting groove 36 until the right outer surface of the first connecting plate 35 contacts the left outer surface of the first connecting groove 36, completing the fixing process. When the blade body 1 and blade head 2 are installed and operation stops, the power mechanism stops providing power to the electromagnet 32. The magnetic force of the electromagnet 32 ​​disappears, and the repulsive force between the electromagnet 32 ​​and the first magnet 34 disappears. The elastic force of the first spring 33, restoring its elastic deformation, then moves the first connecting plate 35 away from the first connecting groove 36 until the first spring 33... After returning to its original position, the first connecting plate 35 moves into the first mounting groove 31. This simplifies the separation of the cutter head 2 from the cutter body 1 after damage, thereby improving the fixing mechanism and ensuring a tighter connection between the cutter body 1 and the cutter head 2. This avoids the common problem of cutter head 2 slipping and falling off due to vibration or external environmental factors after prolonged machining, which can affect the machining efficiency of parts. It also prevents damage to the cutter head 2, thus avoiding wasted resources. Furthermore, the simple separation of the cutter head 2 from the cutter body 1 after damage eliminates the need to replace both, reducing replacement costs and resource waste. This improves overall practicality and versatility. The invention also incorporates a second mounting groove 41. Since higher workpiece material strength and hardness result in more work consumption and heat generation during cutting, this invention addresses these issues.The higher the cutting temperature, the more significant the impact on the workpiece material's strength. When the cutting head 2 cuts the workpiece and the temperature rises, the second air bladder 43 contains gases that expand easily when heated, such as carbon dioxide. Heat is transferred to the second air bladder 43 through the heat-conducting iron 48, causing the gas inside the second air bladder 43 to expand. The expansion force overcomes the elastic force of the second spring 42, pushing the second connecting plate 44 towards the inner surface of the fourth connecting groove 45 until the second connecting plate 44 is in complete contact with the fourth connecting groove 45, completing the fixing work. After the tool body 1 and the cutting head 2 are installed and the work stops, the temperature decreases, the gas inside the second air bladder 43 returns to its original state, and the elastic force of the second spring 42, which restores its elastic deformation, drives the second connecting plate 44 away from the fourth connecting groove 45 until the second spring 42 returns to its original position, and the second connecting plate 44 moves away from the fourth connecting groove 45. When plate 44 moves into the fourth connecting groove 45, the separation operation between cutter head 2 and cutter body 1 is simple after the cutter head 2 is damaged. This improves the tightness of the connection between cutter body 1 and cutter head 2 by enhancing the second fixing mechanism. It avoids the problem of cutter head 2 slipping and falling off due to vibration or external environmental influences after prolonged machining, which would otherwise affect the machining efficiency of the parts. It also prevents damage to cutter head 2, thus avoiding the waste of resources caused by reduced machining efficiency and cutter head 2 utilization. Furthermore, the separation operation between cutter head 2 and cutter body 1 is simple after damage, eliminating the need to replace both cutter head 2 and cutter body 1, resulting in low replacement costs and no resource waste, thus improving overall practicality and versatility.
