Description

Technical Field

[0001] This invention relates to the technical field of auxiliary tools for CNC machine tools, and in particular to a multifunctional tool and method for quickly assembling and disassembling milling cutter sleeves and collets. Background Technology

[0002] During the use of consumer-grade CNC equipment, end mills inevitably break or suffer severe wear, requiring replacement. Tool holders are reusable, but new end mills need to be fitted with tool holders to be used with the equipment. Therefore, it is essential to provide a separate tool for installing and removing tool holders for the entire machine. Furthermore, after the end mill is fitted with a tool holder, it needs to be mounted on the machine's collet for use.

[0003] The basic principle of existing tool holder assembly and disassembly tools is the same as that of vises, which converts rotational motion into linear motion to simultaneously increase force. Related products already exist on the market, such as Maketa Bit Collar Installer V1.0 and V2.0, but each has significant drawbacks.

[0004] Version V1.0 features a cylindrical shape for easy handling and a foolproof design. However, its drawbacks include: the all-metal construction makes it more expensive; the internal components are not visible; there are many small parts that need to be removed when using certain functions, and the lack of storage space on the tool itself increases the risk of loss; during installation, the milling cutter may become misaligned, and forcing the tool to work while the cutter is misaligned could damage it.

[0005] Version V2.0 allows for easy installation and removal without fully tightening the screw. When not in contact, pressing the button allows for quick, straight-line pushing, and the current insertion status of the milling cutter is clearly visible. However, its drawbacks include: the lack of a foolproof mechanism during installation, requiring the user to closely monitor the scale and tighten it to the appropriate position; the reliance on manual tightening of the milling cutter according to the scale introduces uncontrollable errors due to user manual operation; and the platform shape of the tool, requiring it to be used on a table and not held in the hand.

[0006] Furthermore, existing tool holder assembly / disassembly tools on the market do not have the function of disassembling and assembling collets. Tool holder assembly / disassembly tools and collet assembly / disassembly tools are two different sets of tools, but both are tools used for milling cutters and are often used together. Summary of the Invention

[0007] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multi-functional tool for quick assembly and disassembly of milling cutter holders and collets, which can simultaneously perform the assembly and disassembly of both the holder and collet without the need for multiple sets of tools.

[0023] The multi-functional tool for quick assembly and disassembly of milling cutter sleeves and collets according to embodiments of the present invention has at least the following beneficial effects: This invention provides a screw cap assembly that is detachably connected to the screw assembly. The screw cap assembly can be pulled out of the screw assembly and used independently as a collet removal and installation wrench. This allows a set of tools to have both tool sheath removal and installation and collet removal and installation functions. This solves the problem that existing tool sheath removal and installation tools and collet removal and installation tools are independent of each other, reduces tool equipment costs, and reduces tool storage space.

[0024] This invention improves the integration and versatility of tools by using a stepped double-diameter pin with a first diameter segment and a second diameter segment, which can be flipped to adapt to two different sizes of collets, eliminating the need for multiple special wrenches of different sizes.

[0025] This invention solves the problem of "not being able to see the internal situation" in V1.0 by setting a transparent intermediate cylinder, which allows users to intuitively observe the current loading status of the milling cutter.

[0026] This invention features a milling cutter fixing block made of soft rubber. The milling cutter fixing block deforms and is inserted into the front cover with an interference fit. When the user holds the tool at an angle, such as when turning it with the barrel facing upwards, a slight interference fit and static friction are generated between the soft rubber and the milling cutter, making it less likely for the milling cutter to fall off after it is inserted.

[0027] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation, connection, and linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] The following describes, with reference to the accompanying drawings, a multi-functional tool and method for quickly assembling and disassembling milling cutter sleeves and collets according to an embodiment of the present invention.

[0036] Reference Figure 1 This invention provides an embodiment of a multi-functional tool for quick assembly and disassembly of milling cutter sleeves and collets.

[0037] In this embodiment, the basic working principle of this tool is consistent with that of a vise. By converting rotary motion into linear motion, force is simultaneously amplified. The vise rotates by cranking the handle, which in turn drives the screw nut to move linearly, thereby causing the movable jaws to slide along the guide rail, thus opening or closing the jaws. This tool also utilizes a screw drive mechanism to convert rotary motion into linear motion, achieving force amplification to complete the disassembly and assembly of the tool holder.

[0038] In this embodiment, the multi-functional tool mainly includes a front cover 100, a milling cutter fixing block 200, an intermediate cylinder 300, a screw assembly 400, and a cap screwing assembly 500.

[0039] The front cover 100 is used to accommodate the milling cutter fixing block 200 and the cutter sleeve. The rear end of the front cover 100 can be connected to and separated from the intermediate cylinder 300 by threads.

[0040] The milling cutter fixing block 200 is located inside the front cover 100 and is used to fix the milling cutter.

[0041] The intermediate cylinder 300 is connected between the front cover 100 and the screw assembly 400. The intermediate cylinder 300 moves forward or backward relative to the screw assembly 400 by rotating clockwise or counterclockwise to achieve screw drive and realize the connection and separation with the front cover 100.

[0042] The cap assembly 500 and the screw assembly 400 are detachably connected.

[0043] Reference Figure 2 For the cap screwing assembly 500, the cap screwing assembly 500 includes a cap screwing 502, a screwing block 503 disposed on the cap screwing 502, a pin mounting member 504 disposed on the cap screwing 502, and a pin 505 disposed on the pin mounting member 504.

[0044] Among them, the screw cap 502 is made of plastic. As the main body of the screw cap assembly 500, the screw cap 502 can play the role of gripping and applying force.

[0045] In some preferred embodiments of the present invention, the outer peripheral surface of the screw cap 502 may be roughened, as shown in the accompanying drawings of this example, to facilitate hand gripping or tool bag clamping.

[0046] The screw block 503 is tightly connected to the screw cap 502 by interference fit or adhesive bonding. The screw block 503 is used to transmit torque when disassembling and assembling the collet, improve the reliability of force application, and prevent the plastic screw cap from deforming or being damaged under force.

[0047] In some preferred embodiments of the present invention, the screw block 503 can be made of metal to improve the connection strength and extend the service life.

[0048] In some preferred embodiments of the present invention, the screw block 503 can be connected to the screw cap 502 by injection molding in the form of an insert, which facilitates manufacturing and improves the connection strength.

[0049] For pin 505, pin 505 is installed on pin mounting part 504, which in turn is installed on screw cap 502, so that pin 505 is fixed to the front end of screw cap 502. Pin 505 has a stepped structure, with a first diameter section and a second diameter section, which are respectively set at both ends of pin 505 to adapt to different sizes of collets.

[0050] In some preferred embodiments of the present invention, the pin 505 can be made of carbon steel to meet the usage requirements. At the same time, the cost is low, which also reduces maintenance and replacement costs. Therefore, the pin 505 can also be called carbon steel pin 505, indicating its performance.

[0051] The first magnet 501 is disposed inside the screw cap 502 and is tightly connected to the screw cap 502 by interference fit or adhesive bonding, so as to realize the detachable connection between the screw cap assembly 500 and the screw assembly 400.

[0052] Reference Figure 3 For the screw assembly 400, the screw assembly 400 includes a screw 402, a second magnet 401 disposed on the screw 402, and a carbon steel shaft 403 disposed on the screw 402.

[0053] Among them, the screw 402 is a slender rod with external threads on its surface, which is used to cooperate with the internal threads of the intermediate cylinder 300 to realize helical transmission.

[0054] The second magnet 401 is tightly connected to the screw 402 by interference fit or adhesive bonding. The second magnet 401 is used to attract and cooperate with the first magnet 501 of the cap screwing assembly 500, so as to realize the detachable connection between the cap screwing assembly 500 and the screw assembly 400.

[0055] The carbon steel shaft 403 can also be tightly connected to the screw 402 by interference fit or adhesive bonding. The carbon steel shaft 403 is used to abut the end of the milling cutter during the tool disassembly process to transmit thrust.

[0056] The cap screwing assembly 500 and the screw assembly 400 are detachably connected by a first magnet 501 and a second magnet 401, so that the cap screwing assembly 500 can be pulled out from the screw assembly 400 and used as a collet removal wrench.

[0057] Reference Figures 4 to 7 This document introduces the application of this embodiment in the process of disassembling and assembling collets.

[0058] Reference Figure 4When the user needs to disassemble or assemble the collet, first pull the cap assembly 500 out of the screw assembly 400.

[0059] Since the cap screw assembly 500 and the screw assembly 400 are connected only by the magnetic attraction of the first magnet 501 and the second magnet 401, the user only needs to apply a pulling force to overcome the magnetic attraction to separate the cap screw assembly 500 from the screw assembly 400.

[0060] It is easy to understand that this invention, through its structure, allows the cap-tightening assembly 500 to be used independently as a collet wrench, achieving a multi-functional device without requiring the user to carry a separate dedicated collet wrench. Simultaneously, the magnetic connection method is simple to operate, requiring no additional disassembly or assembly tools, allowing a single person to complete the separation and assembly operations.

[0061] Reference Figure 5 After pulling the cap assembly 500 out of the screw assembly 400, unscrew the pin mounting part 504.

[0062] The pin mounting part 504 is installed on the screw cap 502 by a threaded connection to fix the pin 505. After the pin mounting part 504 is unscrewed, the pin 505 remains on the pin mounting part 504, which makes it easy to flip the pin 505 to switch the diameter section.

[0063] It is easy to understand that this invention, through this design, makes the flipping operation of the pin 505 simple and quick, without the need for additional tools or disassembly / reassembly steps.

[0064] Reference Figure 6 Due to the different specifications of the collets, there are two different operating methods. Select the corresponding diameter segment of pin 505 according to the specifications of the collet.

[0065] When the collet specification is M6 or M6.35, select the second diameter section of pin 505, insert pin 505 into the hole groove of collet 600, and then unscrew cap 502 to disassemble and assemble collet 600.

[0066] When pin 505 is inserted into the slot of the collet, pin 505 engages with the slot to achieve positioning and prevent rotation.

[0067] The collet has a slotted chuck, the core function of which is to provide space for elastic deformation. The collet needs to be able to expand slightly when rotating at high speed to accommodate the tool, and then contract evenly to hold the tool holder after locking.

[0068] When the 505 pin is inserted into the slot, it can play a role in positioning and preventing rotation. Specifically, on the one hand, it prevents the chuck from rotating when tightening the nut, ensuring accurate and safe operation. On the other hand, it serves as a fulcrum, allowing the operator to apply torque more effectively.

[0069] Compared to simply relying on the wrench opening for clamping, the pin in this example can support the collet, so that part of the torque on the collet is distributed to the pin, preventing damage to the collet or nut's stress surface due to excessive local pressure.

[0070] Reference Figure 7 When the collet size is M3 or M3.15, select the first diameter segment of pin 505. The first and second diameter segments can be switched by flipping pin 505.

[0071] The pin 505 of the present invention has a stepped structure, that is, two different diameter segments are machined on the same pin, and the two diameter segments are located at the two ends of the pin respectively.

[0072] When a change in specifications is required, simply remove the pin from the pin mount 504, rotate it 180°, and then reinstall it to use the other diameter segment.

[0073] It is easy to understand that this invention, through this design, allows a single pin to be compatible with both M3 / M3.15 and M6 / M6.35 collets, eliminating the need for multiple special wrenches of different sizes, reducing tool costs, decreasing the number of parts, and lowering the risk of loss.

[0074] After inserting the pin 505 into the slot of the collet, the collet can be disassembled or assembled by turning the cap 502.

[0075] Accordingly, refer to Figure 8 The present invention also aims to provide a method for quick disassembly of the collet.

[0076] Specifically, step S1: pull the cap assembly 500 out of the screw assembly 400.

[0077] Step S2: Unscrew the pin mounting part 504.

[0078] Step S3: Select the corresponding diameter segment of pin 505 according to the collet specifications. When the collet specifications are M3 or M3.15, select the first diameter segment of pin 505; when the collet specifications are M6 or M6.35, select the second diameter segment of pin 505. The first and second diameter segments can be switched by flipping pin 505.

[0079] Step S4: Insert pin 505 into the slot of the collet. Pin 505 engages with the slot to provide positioning and prevent rotation, thus preventing the collet from rotating when the nut is turned.

[0080] Step S5: Tighten the cap 502 and apply force through the screw block 503 to disassemble and assemble the collet.

[0081] The assembly and disassembly processes for end mills and tool holders are described separately. For the assembly process, please refer to [link to assembly instructions]. Figures 9 to 15.

[0082] Reference Figure 9 When it is necessary to install the milling cutter, first unscrew the front cover 100 and remove the milling cutter retaining block 200.

[0083] Since the front cover 100 and the middle cylinder 300 are connected by threads, the user can unscrew the front cover 100 to remove it from the middle cylinder 300 and expose the internal space.

[0084] The milling cutter retaining block 200 is located inside the front cover 100. After removing the front cover 100, the milling cutter retaining block 200 can be removed from the front cover 100 so that the corresponding cutting direction can be selected according to the diameter of the milling cutter.

[0085] Reference Figure 10 Since the diameter of the milling cutter varies, the corresponding cutting direction of the milling cutter fixing block 200 needs to be selected according to the diameter of the milling cutter.

[0086] When the end mill diameter is M6 or M6.35, select the second entry hole. The user sequentially installs the tool holder, end mill retainer 200, and end mill into the front cover 100.

[0087] The milling cutter fixing block 200 is made of elastic material (such as soft rubber), which is deformed and installed into the front cover 100. After deformation, it is interference-fitted with the front cover 100 and is not easy to fall off.

[0088] The milling cutter fixing block 200 is provided with a first entry hole and a second entry hole. The two entry holes correspond to different milling cutter diameter specifications, and the user can select the corresponding entry hole according to the actual milling cutter diameter.

[0089] In some preferred embodiments of the present invention, the axes of the first tool inlet hole and the second tool inlet hole can be arranged perpendicularly, which facilitates processing and installation.

[0090] Because the milling cutter retainer block 200 is made of soft, elastic rubber, the M6 ​​cutter inlet hole can hold both M6 and M6.35 milling cutters, providing good dimensional compatibility.

[0091] Reference Figure 11 When the end mill diameter is M3 or M3.15, select the first entry hole. The user then sequentially installs the tool holder, end mill retainer 200, and end mill into the front cover 100.

[0092] Because the milling cutter retaining block 200 is made of soft, elastic rubber, the M3 cutter inlet hole can hold both M3 and M3.15 milling cutters.

[0093] In terms of design, the soft rubber material of the milling cutter retainer 200 generates a slight interference and static friction force between itself and the milling cutter.

[0094] Under normal circumstances, when the user holds the tool at an angle (especially when the end cap is facing upwards), there is a risk that the end cutter retainer block 200 and the end cutter will fall off the front cover 100. However, due to the interference fit and static friction caused by the elastic deformation of the soft rubber, the end cutter is not easy to fall off after it is installed.

[0095] It is easy to understand that this invention, through this design, allows the tool to be used by hand, unlike V2.0 which had to be placed flat on a table for operation, thus conforming to ergonomics.

[0096] Reference Figure 12 Then, the cap assembly 500 and the screw assembly 400 can be assembled by adsorption using the first magnet 501 and the second magnet 401.

[0097] Previously, the cap screwing assembly 500 might have been used separately for collet disassembly and assembly and was in a detached state, or in a stored state.

[0098] When installing the milling cutter, the cap assembly 500 and the screw assembly 400 need to be reassembled to form a complete tool holder assembly and disassembly tool.

[0099] The magnetic connection method makes the assembly process extremely simple. When the user brings the cap assembly 500 close to the screw assembly 400, the two automatically attract each other into place under the magnetic attraction of the first magnet 501 and the second magnet 401.

[0100] Reference Figure 12 Then, the intermediate cylinder 300 can be fitted into the screw assembly 400 and the front cover 100.

[0101] The intermediate cylinder 300 is a transparent tubular component with internal threads on its inner wall, which are used to mate with the external threads of the screw 402 of the screw assembly 400.

[0102] The rear end of the intermediate cylinder 300 is fitted into the screw assembly 400, and the front end is connected to the front cover 100, so that the front cover 100, the intermediate cylinder 300 and the screw assembly 400 are assembled into a complete cylindrical tool.

[0103] Because the intermediate cylinder 300 is made of transparent material (such as transparent plastic), users can intuitively observe the current loading status of the internal milling cutter through the intermediate cylinder 300, avoiding blind operation and solving the problem that the internal situation could not be seen in version V1.0.

[0104] Reference Figure 13 Then, the screw assembly 400 can be turned clockwise to advance the intermediate cylinder 300 relative to the screw assembly 400 until the milling cutter is inserted into the cutter sleeve.

[0105] When the user rotates the screw assembly 400 clockwise, since the intermediate cylinder 300 is connected to the front cover 100, and the milling cutter fixing block 200 and the cutter sleeve inside the front cover 100 are relatively fixed, the screw 402 of the screw assembly 400 moves axially relative to the intermediate cylinder 300 through the threaded engagement.

[0106] It is easy to understand that this invention can convert rotational motion into linear motion through this helical transmission. Through the force amplification effect of the screw, the user only needs a small amount of hand force to generate sufficient tool-loading thrust to smoothly push the milling cutter into the tool holder.

[0107] The transparent intermediate cylinder 300 allows users to observe the installation progress of the milling cutter in real time, avoiding over-tightening or under-tightening.

[0108] Reference Figure 14 Once the milling cutter is fully inserted into the tool holder, the front cover 100 can be unscrewed to remove the milling cutter with the tool holder installed.

[0109] After the end mill is fully inserted into the tool holder, the user unscrews the front cover 100 to remove it from the intermediate cylinder 300, and then removes the end mill with the tool holder installed from the opened end. At this point, the end mill and tool holder are assembled as one unit and can be installed into the collet of the CNC machine for use.

[0110] Reference Figure 15 After the tools are installed, the front cover 100 can be screwed back on and the tools stored away.

[0111] After removing the end mill with the tool holder attached, screw the front cover 100 back onto the intermediate cylinder 300 to restore the tool to its complete cylindrical shape for easy storage and to prevent parts from being lost.

[0112] Since all small parts (such as pin mounting parts 504, pins 505, etc.) are integrated into the main body of the tool, there is no need to store them separately, which solves the problem of V1.0 having a large number of small parts and a greater risk of loss.

[0113] Accordingly, refer to Figure 16 The present invention also aims to provide a method for quickly installing a milling cutter sleeve. Specifically: Step S1: Unscrew the front cover 100 and remove the milling cutter retaining block 200.

[0114] Step S2: Select the corresponding entry direction of the milling cutter fixing block 200 according to the milling cutter diameter. When the milling cutter diameter is M3 or M3.15, select the first entry hole; when the milling cutter diameter is M6 or M6.35, select the second entry hole.

[0115] Step S3: Install the tool holder, the cutter retainer 200, and the cutter in sequence. The cutter retainer 200 is made of elastic material and is installed into the front cover 100 through elastic deformation. After deformation, it has an interference fit with the front cover 100 and is not easy to fall off. After the cutter is installed, because the cutter retainer 200 is made of soft rubber, a slight interference fit and static friction are generated between the cutter and the cutter retainer 200, making the cutter not easy to fall off.

[0116] Step S4: Assemble the cap assembly 500 and the screw assembly 400 by adsorption using the first magnet 501 and the second magnet 401.

[0117] Step S5: Fit the intermediate cylinder 300 into the screw assembly 400 and the front cover 100.

[0118] Step S6: Turn the screw assembly 400 clockwise. The intermediate cylinder 300 will advance relative to the screw assembly 400 until the end mill is installed in the tool holder. The intermediate cylinder 300 is made of transparent material, allowing the user to visually observe the installation status of the end mill through it.

[0119] Step S7: Unscrew the front cover 100 and take out the end mill with the tool holder installed.

[0120] Step S8: Screw the front cover back on and put away the tools.

[0121] For the milling cutter disassembly process, please refer to... Figures 17 to 26 understand.

[0122] Similarly, refer to Figure 17 When it is necessary to disassemble the milling cutter, first unscrew the front cover 100 and remove the milling cutter retaining block 200.

[0123] Similar to the installation process, the user unscrews the front cover 100 to remove it from the intermediate cylinder 300, and takes out the internal milling cutter retaining block 200 to prepare for the installation of the milling cutter with a tool holder to be removed.

[0124] Reference Figure 18 Then, the end mill with the tool holder can be installed into the front cover 100.

[0125] The user places the end mill, which is already installed in the tool holder and needs to be disassembled, into the front cover 100. The end mill retainer 200 is then removed, leaving sufficient space inside the front cover 100 to accommodate the end mill with the tool holder.

[0126] Reference Figure 19 Then, the cap assembly 500 and the screw assembly 400 can be assembled by adsorption using the first magnet 501 and the second magnet 401.

[0127] Similar to the installation process, the capping assembly 500 is brought close to the screw assembly 400, and the two automatically attach and connect under the action of magnetic attraction to form a complete tool disassembly structure.

[0128] Reference Figure 20 Then, the 504 pin mounting piece can be unscrewed.

[0129] During the disassembly process, pin 505 and pin mounting part 504 need to be removed from the cap assembly 500 and moved to the front of the screw assembly 400 to serve as the force-applying parts for disassembling the milling cutter.

[0130] The user screws the pin mounting part 504 off the screw cap 502 in preparation for installation onto the screw assembly 400.

[0131] Reference Figure 21 Then, the pin mounting piece 504 can be screwed into the front of the screw assembly 400.

[0132] After removing the pin mounting part 504 from the cap assembly 500, it is installed onto the front end of the screw 402 of the screw assembly 400. The pin mounting part 504 is fixed to the screw 402 by a threaded connection, so that the pin 505 is installed together with the pin mounting part 504 at the front end of the screw 402.

[0133] Reference Figure 22 Then, pin 505 can be removed and inserted into the front of screw assembly 400.

[0134] After the pin 505 is installed in the front of the screw assembly 400, the end of the pin 505 abuts against the end of the end mill, serving as a fulcrum for disassembling the tool. When the screw assembly 400 moves forward, the screw 402 applies a thrust directly to the end face of the end mill through the pin 505, pushing the end mill out of the tool holder.

[0135] In this embodiment, this multi-functional design is one of the key innovations of the pin 505.

[0136] That is, pin 505 can be used as a positioning pin for disassembling and assembling the collet, for example on the cap assembly 500, or as a force-applying component for disassembling the tool, for example when it is installed at the front of the screw assembly 400.

[0137] The same part performs different functions in different usage scenarios, reducing the number of parts, reducing tool complexity, and eliminating the need for users to switch between different tools.

[0138] Reference Figure 23 Then, the intermediate cylinder 300 can be fitted into the screw assembly 400 and the front cover 100.

[0139] Similar to the loading process, the intermediate cylinder 300 is fitted over the outside of the screw assembly 400 and connected to the front cover 100 to form a complete tool structure.

[0140] Reference Figure 24Then, the screw assembly 400 can be turned clockwise until the milling cutter is removed from the tool holder.

[0141] When the user rotates the screw assembly 400 clockwise, the screw 402 moves axially forward relative to the intermediate cylinder 300.

[0142] The pin 505 at the front end of the screw 402 abuts against the end face of the milling cutter. As the screw 402 moves forward, the pin 505 continuously pushes the milling cutter, pushing it out of the cutter holder.

[0143] The force-amplifying effect of the screw drive mechanism allows users to generate sufficient thrust with minimal hand force, smoothly pushing the tightly fitted milling cutter out of the tool holder, avoiding damage to the milling cutter or tool holder due to excessive force or uneven force application.

[0144] Because the intermediate cylinder 300 is made of transparent material, users can observe the progress of the internal milling cutter being pushed out, thus avoiding excessive force that could cause the milling cutter to splash when it pops out.

[0145] Reference Figure 25 Then, you can unscrew the front cover 100 and take out the knife sheath.

[0146] After the end mill is completely pushed out of the tool holder, the user unscrews the front cover 100 and removes it from the intermediate cylinder 300. At this point, the tool holder and the end mill are separated, and the user removes the empty tool holder and the end mill separately. The tool holder is reusable; a new end mill must be inserted into the tool holder before it can be used with the equipment.

[0147] Reference Figure 26 Then, the pin 505 and pin mounting part 504 can be put back into the screw cap 502, the milling cutter fixing block 200 can be put back into the front cover 100, and the tool can be restored and stored.

[0148] After disassembling the tool, remove pin 505 and pin mounting part 504 from the front of the screw assembly 400 and reinstall them in their original positions on the screw cap 502. Then, put the milling cutter retaining block 200 back into the front cover 100 and screw the front cover 100 back onto the intermediate cylinder 300, restoring the tool to its complete cylindrical shape for easy storage.

[0149] In this embodiment, when the screw 402 is fully screwed down and needs to be retracted, the screw cap assembly 500 can be removed and the screw cap assembly 500 and the screw assembly 400 can be reassembled to achieve the retraction, without the need to rotate multiple turns to reverse the screwing.

[0150] In conventional screw drive mechanisms, when the screw needs to be unscrewed after it has been fully screwed to the bottom, the user must rotate the screw in the opposite direction multiple times to unscrew it, which is cumbersome and time-consuming.

[0151] In this tool, since the cap screwing assembly 500 and the screw assembly 400 are magnetically connected, the user only needs to remove the cap screwing assembly 500 from the screw assembly 400 and then reassemble it at different angles or positions to quickly change the extension state of the screw 402 without having to rotate it multiple times in reverse, which simplifies the operation and improves the efficiency of use.

[0152] Because the cap screwing assembly 500 and the screw assembly 400 have a hexagonal plug-in fit, when the cap screwing assembly 500 rotates, the screw assembly 400 rotates and generates displacement along the rotation axis, causing the screw assembly 400 and the cap screwing assembly 500 to gradually separate.

[0153] In some embodiments of the present invention, the fixing methods of the first magnet 501 and the screw cap 502, the fixing methods of the second magnet 401 and the screw 402, the fixing methods of the screw block 503 and the screw cap 502, and the fixing methods of the carbon steel shaft 403 and the screw 402 are not limited to interference fit or adhesive fit, but can also be achieved by snap-fit, threaded connection and other methods.

[0154] Accordingly, refer to Figure 27 The present invention also aims to provide a method for quickly disassembling a milling cutter sleeve. Specifically: Step S1: Unscrew the front cover 100 and remove the milling cutter retaining block 200.

[0155] Step S2: Install the end mill with the tool holder into the front cover 100.

[0156] Step S3: Assemble the capping assembly 500 and the screw assembly 400 by adsorption using the first magnet 501 and the second magnet 401.

[0157] Step S4: Unscrew the pin mounting part 504 and screw the pin mounting part 504 into the front of the screw assembly 400.

[0158] Step S5: Remove pin 505 and insert it into the front of screw assembly 400. The end of pin 505 abuts against the end of milling cutter, serving as the force fulcrum for tool removal.

[0159] Step S6: Fit the intermediate cylinder 300 into the screw assembly 400 and the front cover 100.

[0160] Step S7: Turn the screw assembly 400 clockwise. The intermediate cylinder 300 moves forward relative to the screw assembly 400. The screw assembly 400 pushes the milling cutter through the pin 505 until the milling cutter is removed from the cutter holder.

[0161] Step S8: Unscrew the front cover 100 and remove the blade sheath.

[0162] Step S9: Reinstall pin 505 and pin mounting part 504 back onto screw cap 502, put milling cutter fixing block 200 back onto front cover 100, restore the tool and store it.

[0163] When the screw 402 needs to be unscrewed after being fully tightened, simply remove the screw cap assembly 500 and reassemble the screw cap assembly 500 and screw assembly 400 to achieve unscrewing; there is no need to rotate it multiple times in reverse.

[0164] In some embodiments of the present invention, the detachable connection method of the cap assembly 500 and the screw assembly 400 is not limited to magnetic attraction, but can also be replaced by snap-fit, soft rubber interference fit, etc.

[0165] In some embodiments of the present invention, the milling cutter fixing block 200 is not limited to soft rubber material, and can also achieve the fixing function through hard rubber buckle structure or magnetic attraction.

[0166] In some embodiments of the present invention, the engagement between the intermediate cylinder 300 and the screw assembly 400 is not limited to a threaded engagement, and relative movement can also be achieved in other ways.
