Description

Technical Field

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

[0002] Knives are mainly divided into cutting knives, used for side cutting, and scrapers, used for scraping. A cutting knife is an art and craft tool, often with a pull-out design, consisting of a plastic handle and a blade. The cutting edge of the blade is usually parallel to the axis of the handle or housing, and it is primarily used for cutting, such as cutting paper or cardboard. A scraper, on the other hand, typically has a blade perpendicular to or orthogonal to the axis of the handle, and is used for scraping, such as scraping paint or glue residue from flat surfaces. Cutting knives and scrapers are two separate hand tools and are often not interchangeable. Users typically need to purchase, store, and carry both separate tools, which can be inconvenient.

[0003] While existing deformable cutting tools can switch between cutting and scraping modes, their structure is relatively complex and their operation is inconvenient. Summary of the Invention

[0004] One objective of this invention is to provide a deformable cutting tool with a compact structure. By moving the tool holder along the first and second guide rails, the tool can be quickly positioned at multiple angles, allowing it to be used as a utility knife or a scraper, thereby improving work efficiency.

[0005] Another objective of this invention is to provide a deformable cutting tool in which the drive component can be elastically locked to the tool holder by an anti-rotation component, thereby preventing accidental relative rotation between the tool holder and the drive component and improving the reliability and safety of the cutting tool during use.

[0006] Another objective of this invention is to provide a deformable cutting tool whose tool holder allows for quick blade replacement via a tool change button, making operation simple.

[0007] Another objective of this invention is to provide a deformable cutting tool with a simple structure that does not require additional complex components. The movement path of the tool holder is defined by the first guide rail and the second guide rail on the surface of the tool shell, and the cutting blade is smoothly transitioned to multiple positioning positions from 0° to 90°, thereby reducing production costs.

[0008] Another objective of this invention is to provide a deformable cutting tool that generates a thrust that pushes the cutting tool holder along the rotation direction by deflecting and guiding the first and second guide members on the tool holder to an appropriate direction, thereby rotating the tool holder to a preset position and satisfying the multi-purpose use requirements of the cutting tool in the longitudinal, transverse, and oblique directions, thus improving the application range of the cutting tool.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a deformable cutting tool, comprising: a cutting tool shell, the cutting tool shell having a receiving cavity and a port, the port being opened at the front end of the cutting tool shell; a cutting tool holder, the cutting tool holder carrying a cutting blade, the cutting tool holder being rotatably mounted in the receiving cavity, the front side of the cutting tool holder having a plurality of stop grooves; a first guide assembly, the first guide assembly having a first guide rail and a driving member, the driving member being drivably connected to the front side of the cutting tool holder, thereby causing the cutting tool holder to move along the first guide rail; and a second guide assembly, the second guide assembly having a fixed surface and a second guide rail, the second guide rail being opened on the fixed surface, the back side of the cutting tool holder being pivotally connected to the second guide rail, thereby causing the cutting tool holder to move along the second guide rail. The guide rail moves, wherein when the driving member moves longitudinally relative to the fixed surface along the axial direction, the tool holder can selectively rotate into or out of the receiving cavity, so that the tool holder can alternately change direction at multiple positioning angles between longitudinal and lateral positions; a push button assembly is connected to the driving member to push the driving member to move axially along the first guide rail; an anti-rotation member is rotatably connected to the driving member, one end of the anti-rotation member is movably connected to the push button assembly, and the other end of the anti-rotation member has a stop portion protruding towards one side of the tool holder, and the anti-rotation member rotates under the action of the push button assembly so that the stop portion can be elastically locked into the stop groove of the tool holder.

[0010] Preferably, the driving member has a driving surface, which can be fitted with a sliding member or directly serve as a sliding member; the first guide rail and the second guide rail are linear and / or arc-shaped structures, and the extension directions of the first guide rail and the second guide rail are at least partially different. The second guide rail has a main support section, which extends outward along a direction deviating from the first guide rail, so that the tool holder is connected to the fixed surface and the driving surface in at least two partially different directions. When the tool holder gradually changes direction and turns under the combined force of the fixed surface and the driving surface, the tool holder gradually rotates out of or back into the receiving cavity from the port.

[0011] Preferably, the second guide rail is further provided with a straight section, and the main support section and the straight section are integrally connected. The main support section extends outward in an arc or bends in a direction deviating from the straight section. The extension direction of the straight section is the same as the extension direction of the first guide rail. When the tool holder moves linearly along the straight section of the second guide rail and the direction of the first guide rail, the blade on the tool holder can be in a retracted state within the retracted receiving cavity or an extended state with the protruding port. When the tool holder moves in a turning direction along the main support section of the second guide rail and the direction of the first guide rail, the blade on the tool holder can change direction at multiple positioning angles between the longitudinal position and the transverse position.

[0012] Preferably, the blade housing includes an upper shell and a lower shell, and the driving member is located in the receiving cavity between the upper shell and the blade holder. The upper shell is provided with an elongated push-button groove that extends along the axial direction. The deformable blade also includes a positioning member disposed between the push-button assembly and the driving member. The positioning member is provided with a positioning groove that is formed on the surface of the positioning member. The push-button groove connects the positioning groove to the outside. The lower end of the push-button assembly passes through the push-button groove and the positioning groove and is connected to the driving member, thereby pushing the driving member to move axially along the first guide rail. The push-button assembly can be elastically locked in the positioning groove, so that the blade of the blade holder is locked in a longitudinal position, a transverse position, or a transitional position between the longitudinal position and the transverse position.

[0013] As a preferred embodiment, the push button assembly includes a push button bracket and a push button spring. The push button bracket passes through the push button slot and the positioning slot and is connected to the driving member. One end of the push button spring abuts against the push button bracket, and the other end of the push button spring abuts against the driving member, so that the push button bracket can be movably locked in the positioning slot. One end of the push button bracket extending out of the outer side of the upper shell is fixedly connected to a push button panel, which facilitates pushing the push button bracket to move the driving member along the first guide rail.

[0014] Preferably, the tool holder includes a first tool post, an intermediate tool post, and a second tool post, the intermediate tool post being elastically connected to the first tool post and the second tool post, and the cutting blade being detachably mounted between the second tool post and the intermediate tool post; the tool holder includes a first guide and a second guide, the first guide protruding radially outward from the first tool post, thereby enabling the first guide to drive the tool holder to translate and / or rotate along the first guide rail, and the second guide protruding radially outward from the second tool post eccentrically relative to the first guide, thereby enabling the second guide to drive the tool holder to translate and / or rotate along the second guide rail.

[0015] Preferably, the deformable cutting tool further includes a tool changing assembly for replacing the blade. The tool changing assembly includes a tool changing button and a return spring. The return spring allows the tool changing button to be movably disposed on the lower shell of the tool holder. The tool changing button has a protruding portion protruding towards the side of the tool holder. The second tool holder also has a through tool changing hole. The main body of the intermediate tool holder also has an extension protruding towards the side of the second tool holder. The extension extends into the tool changing hole. When the tool holder is in the second longitudinal position, the protruding portion aligns with the tool changing hole and abuts against the extension. Pressing the tool changing button causes the intermediate tool holder to move towards the first tool holder side, thereby separating the fixing part from the mounting hole, allowing the blade to be replaced.

[0016] As a preferred embodiment, the tool holder further includes a spring clip, and the first tool holder has a spring clip groove for mounting the spring clip on the side facing the second tool holder, as well as a first mounting groove for accommodating the intermediate tool holder. The spring clip can provide a force against the second tool holder to the intermediate tool holder, so that the blade is clamped between the intermediate tool holder and the second tool holder.

[0017] Preferably, the blade has a through-hole and a mounting hole. The main body of the intermediate tool holder has a limiting part and a fixing part protruding from the side facing the second tool holder. The limiting part is adapted to cooperate with the limiting hole, and the fixing part is adapted to pass through the mounting hole to fix the blade. The second tool holder has a second mounting groove on the side facing the intermediate tool holder. The second mounting groove is used to accommodate the end of the fixing part.

[0018] As a preferred embodiment, the push button bracket includes a first connecting segment and a second connecting segment distributed perpendicular to the driving surface. The positioning groove includes an elongated moving area extending along the axial direction and a plurality of spaced positioning areas. The first connecting segment passes through the push button groove of the upper shell and is adapted to move along the moving area of ​​the positioning groove. The second connecting segment is fixedly connected to the driving member and is adapted to cooperate with the positioning areas to lock the driving member.

[0019] The drive member is provided with a joint, a first connecting hole and a second connecting hole. The joint is adapted to cooperate with the first guide rail so that the drive member moves along the first guide rail. The first connecting hole is adapted to connect with the first guide member on the tool holder. The second connecting hole is adapted to connect with the second connecting section of the push button bracket. When the push button assembly is pushed, the tool holder can be driven to move through the drive member.

[0020] The tail end of the blade has a curved hook for prying objects. Attached Figure Description

[0043] It should be noted that terms such as "front" and "back" are used to indicate orientation, facilitate the description of the present invention and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They can also be expressed as "above", "below", or "one side" or "the other side", and should not be construed as limiting the specific scope of protection of the present invention.

[0044] A deformable cutting tool, such as Figures 1 to 11 As shown, the device includes: a blade housing 10, a blade holder 30, a first guide assembly, and a second guide assembly. The blade housing 10 has a receiving cavity 13 and a port 14. The port 14 is located at the front end of the blade housing 10, allowing the receiving cavity 13 to communicate with the outside. The blade holder 30 is used to carry the blade 35. The blade holder 30 is rotatably mounted in the receiving cavity 13 and can extend out of or retract into the receiving cavity 13 through the port 14. The first guide assembly has a first guide rail 222 and a driving member 23. The driving member 23 is drivably connected to the blade holder 30. The front side of the tool holder 30 allows it to move along the first guide rail 222. That is, the driving member 23 is pivotally connected to the front side of the tool holder 30, and the driving member 23 moves along the first guide rail 222. Further, under the driving action of the driving member 23, the tool holder 30 can move along the first guide rail 222. The second guide assembly has a fixed surface 122 and a second guide rail 121. The second guide rail 121 is formed on the fixed surface 122, and the back side of the tool holder 30 is pivotally connected to the second guide rail 121, allowing the tool holder 30 to move along the second guide rail 121. It can be understood that the tool holder 30 is simultaneously connected to the driving member 23 and the second guide rail 121, allowing it to move along both the first guide rail 222 and the second guide rail 121. Through the joint guidance of the first guide rail 222 and the second guide rail 121, the tool holder 30 can translate and / or rotate. When the driving member 23 moves longitudinally relative to the fixed surface 122 along the axial direction, the tool holder 30 can selectively rotate into or out of the receiving cavity 13, allowing the tool holder 30 to alternately change direction at multiple positioning angles between longitudinal and lateral positions. In other words, through the driving action of the driving member 23, the tool holder 30 can translate and / or rotate under the guidance of the first guide rail 222 and the second guide rail 121, further enabling rapid multi-angle positioning of the tool. This allows the tool to be used interchangeably between a utility knife and a scraper, facilitating operation, improving work efficiency, and resulting in a compact structure.

[0045] In some embodiments, such as Figure 11 and Figure 12As shown, the tool holder 30 includes a first guide 311 and a second guide 321. The first guide 311 and the second guide 321 are respectively offset on the front and back of the tool holder 30. The first guide 311 protrudes from the front of the tool holder 30 and is pivotally connected to the drive member 23, so that the first guide 311 drives the tool holder 30 to translate and / or rotate along the first guide rail 222. The second guide 321 protrudes from the back of the tool holder 30 and is pivotally connected to the second guide rail 121, so that the second guide 321 drives the tool holder 30 to translate and / or rotate along the second guide rail 121. This allows the longitudinal driving force of the drive member 23 on the first guide 311 to be converted into a steering force on the tool holder 30 at multiple positioning angles. In other words, the first guide 311 is connected to the drive member 23, and the first guide 311 moves in conjunction with the first guide rail 222, and the second guide 321 moves in conjunction with the second guide rail 121 to generate deflection and guidance, thereby generating a thrust that pushes the tool holder 30 along the rotation direction, so that the tool holder 30 rotates to a preset position, satisfying the multi-purpose use requirements of the blade 35 in the longitudinal, transverse and oblique directions, and improving the application range of the tool.

[0046] Specifically, such as Figures 1 to 10 As shown, the projections of the first guide 311 and the second guide 321 on the fixed surface 122 do not coincide. When the first guide 311 moves along the first guide rail 222 and the second guide 321 moves along the second guide rail 121, the distance between the projections of the first guide 311 and the second guide 321 on the fixed surface 122 remains unchanged. Furthermore, under the guidance of the first guide rail 222 and the second guide rail 121, the tool holder 30 can smoothly translate and / or rotate to achieve multi-angle positioning of the tool, realize multiple uses of one tool, and facilitate storage and carrying.

[0047] In some embodiments, such as Figure 11 and Figure 12 As shown, the driving member 23 has a driving surface 234, which can be fitted with a slider 50 or directly serve as a slider 50. The first guide member 311 can be pivotally connected to the front end of the driving surface 234. Specifically, when the driving surface 234 directly serves as a slider 50, in an optional embodiment, as shown... Figure 2 As shown, the first guide 311 on the tool holder 30 is pivotally connected to the front end of the driving surface 234. When the driving surface 234 moves along the first guide rail 222, it drives the first guide 311 to move along the first guide rail 222. At the same time, the second guide 321 moves along the second guide rail 121, further enabling the tool holder 30 to smoothly translate and / or rotate, thereby achieving multi-angle positioning of the tool. When the sliding member 50 is mounted on the driving surface 234, in an optional embodiment, as shown... Figure 18As shown, the first guide 311 on the tool holder 30 is pivotally connected to the front end of the driving surface 234, and the rear end of the driving surface 234 is pivotally connected to the sliding member 50. When the sliding member 50 moves longitudinally along the axial direction, it can push the driving surface 234 to translate and / or rotate, further driving the first guide 311 to move along the first guide rail 222. At the same time, the second guide 321 moves along the second guide rail 121, so that the tool holder 30 smoothly translates and / or rotates to achieve multi-angle positioning of the tool. It can be understood that the first guide 311 can be connected to the driving member 23, and the driving member 23 can move along the first guide rail 222, so that the first guide 311 can move indirectly along the first guide rail 222. Alternatively, the first guide 311 can directly cooperate with the first guide rail 222, and under the drive of the driving member 23, the first guide 311 can move along the first guide rail 222.

[0048] In some embodiments, such as Figures 1 to 10 As shown, the first guide rail 222 and the second guide rail 121 are linear and / or arc-shaped structures. The extension directions of the first guide rail 222 and the second guide rail 121 are at least partially different. The second guide rail 121 is provided with a main support section 1212, which extends outward along a direction deviating from the first guide rail 222, so that the tool holder 30 is connected to the fixed surface 122 and the driving surface 234 in at least two partially different directions. When the tool holder 30 gradually changes direction and turns under the combined force of the fixed surface 122 and the driving surface 234, the tool holder 30 gradually rotates out of or back into the receiving cavity 13 from the port 14. In other words, when the first guide 311 moves along the first guide rail 222 and the second guide 321 moves along the main support section 1212 of the second guide rail 121, the distance between the projections of the first guide 311 and the second guide 321 on the fixed surface 122 remains unchanged, while the extension direction of the main support section 1212 deviates from the extension direction of the first guide rail 222. This causes the tool holder 30 to rotate in a different direction under the combined action of the fixed surface 122 and the driving surface 234. For example, it can rotate out of the receiving cavity 13 from the port 14, making the blade perpendicular to the axis for use as a scraper, or rotate back from the port 14 to the receiving cavity 13, making the blade parallel to the axis for use as a cutting knife, or make the blade at other angles to the axis to achieve multi-angle positioning of the tool and realize multiple uses of one tool.

[0049] Specifically, such as Figures 1 to 10As shown, the second guide rail 121 has a straight section 1211, and a main support section 1212 is integrally connected to the straight section 1211. The main support section 1212 extends outward in an arc or bends in a direction deviating from the straight section 1211. The extension direction of the straight section 1211 is the same as the extension direction of the first guide rail 222. When the tool holder 30 moves linearly along the direction of the straight section 1211 of the second guide rail 121 and the direction of the first guide rail 222, the blade 35 on the tool holder 30 can be in a retracted state within the retracted receiving cavity 13 or an extended state extending from the port 14. When the tool holder 30 moves in a turning direction along the direction of the main support section 1212 of the second guide rail 121 and the direction of the first guide rail 222, the blade 35 on the tool holder 30 can change direction at multiple positioning angles between the longitudinal and transverse positions. In the longitudinal position, the cutting edge of the blade 35 is parallel to the axis direction; in the transverse position, the cutting edge of the blade 35 is perpendicular to the axis direction.

[0050] In other words, when the first guide 311 on the tool holder 30 moves along the first guide rail 222 and the second guide 321 is located on the straight section 1211 of the second guide rail 121, the cutting edge is parallel to the axial direction, and the tool holder 30 translates longitudinally along the axial direction, so that the cutting edge extends out of the receiving cavity 13 from the port 14 or retracts into the receiving cavity 13; when the first guide 311 on the tool holder 30 moves along the first guide rail 222 and the second guide 321 is located on the main support section 1212 of the second guide rail 121, the tool holder 30 can move and rotate in a different direction, so that the angle between the cutting edge and the axial direction changes, so as to achieve multi-angle positioning and meet various usage requirements.

[0051] In another alternative embodiment, such as Figure 18 As shown, the first guide rail 222 extends in an arc shape, and the main support section 1212 of the second guide rail 121 extends in an arc shape in a direction deviating from the first guide rail 222. When the tool holder 30 moves in a turning direction along the direction of the first guide rail 222 and the main support section 1212 of the second guide rail 121, the blade 35 on the tool holder 30 can change direction between multiple positioning angles in the longitudinal and transverse positions.

[0052] In some embodiments, such as Figure 11 As shown, the blade housing 10 includes an upper shell 11 and a lower shell 12, which are fixed together by fasteners 15. The drive member 23 is located in the receiving cavity 13 between the upper shell 11 and the lower shell 12, and is disposed between the upper shell 11 and the blade holder 30. The upper shell 11 is provided with an elongated push button groove 111, which extends along the axial direction. The fixing surface 122 is located on the inner surface of the lower shell 12. The second guide rail 121 is formed on the inner surface of the lower shell 12, so as to pivotally connect with the second guide member 321 on the blade holder 30.

[0053] In some embodiments, such as Figure 11 and Figure 12As shown, the deformable cutting tool further includes a moving assembly 20, which includes a push button assembly 21 and a positioning member 22. The positioning member 22 is disposed between the push button assembly 21 and the driving member 23. The positioning member 22 is provided with a first guide rail 222 and a positioning groove 221. The first guide rail 222 is formed on the back of the positioning member 22 and can be connected to the driving member 23. The driving member 23 further causes the first guide member 311 to move along the direction of the first guide rail 222. The positioning groove 221 is formed on the surface of the positioning member 22. The push button groove 111 of the upper shell 11 can connect the positioning groove 221 to the outside. The lower end of the push button assembly 21 passes through the push button groove 111 and the positioning groove 221 and is connected to the driving member 23, so as to push the driving member 23 to move axially along the first guide rail 222. The push button assembly 21 can be elastically locked in the positioning groove 221, so that the cutting tool 35 of the tool holder 30 is locked in a longitudinal position, a transverse position, or a transitional position between the longitudinal and transverse positions.

[0054] In other words, the positioning member 22 is fixedly installed with the upper shell 11. The back of the positioning member 22 is provided with a first guide rail 222, which can cooperate with the joints 232 protruding on both sides of the driving member 23, so that the driving member 23 can move along the first guide rail 222. Furthermore, the first guide member 311 on the tool holder 30 is pivotally connected to the first connecting hole 233 at the front end of the driving member 23, so that the first guide member 311 can move along the first guide rail 222. The inner surface of the lower shell 12 is provided with a second guide rail 121, which can be connected to the second guide member 321 on the tool holder. The lower end of the push button assembly 21 passes through the push button groove 111 of the upper shell 11 and the positioning groove 221 of the positioning member 22 and is connected to the rear end of the driving member 23. The push button can push the driving member 23 to move, and further enable the tool holder 30 to translate and / or rotate. Furthermore, the push button assembly 21 can be elastically locked into the positioning groove 221, allowing the tool holder 30 to be locked in a selectable position, such that the blade 35 is in a longitudinal position, a transverse position, or other selectable positions between the longitudinal and transverse positions, for example, at 30°, 45°, or 60° with respect to the axis. The combined action of the first guide rail 222 on the back of the positioning member 22 and the second guide rail 121 on the surface of the tool housing 10 defines the movement path of the tool holder 30, allowing the blade 35 to smoothly transition to multiple positioning positions without the need for additional complex components, thus reducing production costs. In an optional embodiment, the positioning member 22 and the upper housing 11 are integrally formed.

[0055] In some embodiments, such as Figure 11 and Figure 12As shown, the push button assembly 21 includes a push button bracket 211 and a push button spring 212. The push button bracket 211 passes through the push button groove 111 and the positioning groove 221 and is connected to the drive member 23. One end of the push button spring 212 abuts against the push button bracket 211, and the other end of the push button spring 212 abuts against the drive member 23, so that the push button bracket 211 can be movably locked in the positioning groove 221. One end of the push button bracket 211 extending out of the outer side of the upper shell 11 is fixedly connected to the push button panel 213, which facilitates pushing the push button bracket 211 to make the drive member 23 move along the first guide rail 222.

[0056] Furthermore, the push button bracket 211 includes a first connecting segment 2111 and a second connecting segment 2112 distributed perpendicular to the drive surface 234. The positioning groove 221 includes an elongated moving area 2211 extending along the axial direction and a plurality of spaced positioning areas 2212. The first connecting segment 2111 passes through the push button groove 111 of the upper shell 11 and is adapted to move along the moving area 2211 of the positioning groove 221. The second connecting segment 2112 is connected to the second connecting hole 231 on the drive member 23, and the second connecting segment 2112 is adapted to cooperate with the positioning areas 2212 to lock the drive member 23, so that the tool holder 30 is held in the selectable position. That is, the first connecting segment 2111 of the push button bracket 211 is adapted to move along the push button groove 111 of the upper shell 11, and the first connecting segment 2111 is also adapted to move along the positioning groove 221 of the positioning member 22. The second connecting section 2112 of the push button bracket 211 is adapted to cooperate with the positioning area 2212 of the positioning groove 221 to position the blade holder 30 and further position the blade 35.

[0057] Specifically, pressing and pushing the push button assembly 21 compresses the push button spring 212, causing the push button bracket 211 to move inward. The second connecting section 2112 of the push button bracket 211 separates from the positioning area 2212 of the positioning groove 221 of the positioning member 22. The first connecting section 2111 and the moving area 2211 cooperate, allowing the push button assembly 21 to drive the driving member 23 to move. Releasing the push button assembly 21 causes the push button bracket 211 to move outward. The second connecting section 2112 of the push button bracket 211 cooperates with the positioning area 2212 to lock the driving member 23, further positioning the position of the tool holder 30. The position and shape of the tool holder 30 can be changed and locked by one-handed operation, improving the convenience and safety of operation. Furthermore, the tool holder 30 can move and turn smoothly through the first guide rail 222 and the second guide rail 121, making pressing and pushing the push button assembly 21 easier and smoother.

[0058] Furthermore, such as Figures 13 to 15As shown, the deformable cutting tool also includes an anti-rotation component 70, which is rotatably connected to the drive component 23 and can move longitudinally along the axial direction together with the drive component 23. One end of the anti-rotation component 70 is movably connected to the push button assembly 21. When the push button assembly 21 moves towards the inside or outside of the tool housing 10 in the direction of the vertical fixed surface 122, it can drive the anti-rotation component 70 to rotate relative to the drive component 23. The other end of the anti-rotation component 70 is provided with a stop portion 71 protruding towards the side of the tool holder 30. The front of the tool holder 30 is provided with a plurality of stop grooves 314 for accommodating the stop portion 71. When the anti-rotation component 70 rotates under the action of the push button assembly 21, the stop portion 71 can engage or disengage with the stop groove 314. Understandably, pressing the push button assembly 21 moves it inward toward the tool housing 10, causing the anti-rotation member 70 to rotate, thus separating the stop portion 71 from the stop groove 314, allowing the tool holder 30 to rotate relative to the drive member 23. Releasing the push button assembly 21 moves it outward toward the tool housing 10, causing the anti-rotation member 70 to rotate, thus engaging the stop portion 71 with the stop groove 314, locking the tool holder 30 with the drive member 23, and maintaining the tool holder 30 in a longitudinal position, a transverse position, or other selectable position between the longitudinal and transverse positions. In other words, the combined action of the push button assembly 21 and the positioning groove 221, and the anti-rotation member 70 and the tool holder 30, locks the position of the tool holder 30, improving the reliability and safety of the deformable tool during use. In another alternative embodiment, an anti-rotation spring is provided below the side of the anti-rotation member 70 near the push button assembly 21. The anti-rotation spring provides torque to the anti-rotation member 70, causing the stop portion 71 on the other side of the anti-rotation member 70 to move downward and engage with the stop groove 314.

[0059] In some embodiments, such as Figures 1 to 10As shown, the straight section 1211 of the second guide rail 121 coincides with the first guide rail 222 in a direction perpendicular to the axis. The main support section 1212 extends radially outward from the front end of the straight section 1211 in an arc shape. When the driving member 23 moves along the first guide rail 222, the tool holder 30 can be moved along the second guide rail 121 to the retracted position, the first longitudinal position, the second longitudinal position, the transition position, and the lateral position, respectively. When the second guide member 321 is located at the starting end of the straight section 1211 of the second guide rail 121, the tool holder 30 is in the retracted position longitudinally, and the blade 35 is retracted into the receiving cavity 13. When the second guide member 321 moves along the straight section 1211 of the second guide rail 121, the tool holder 30 is in the retracted position longitudinally, and the blade 35 is retracted into the receiving cavity 13. When section 1211 moves forward, the blade holder 30 is in the first longitudinal position where the blade 35 partially extends out of the port 14 and the second longitudinal position where the blade 35 fully extends out of the port 14. When the second guide 321 moves from the straight section 1211 to the main support section 1212, the blade holder 30 turns to the transition position. The blade holder 30 turns out of the receiving cavity 13 and the turning angle is approximately 0°~90° or 90°~180°. The blade 35 is converted to an inclined state and can be used as an oblique scraper. When the second guide 321 moves to the end of the main support section 1212, the blade holder 30 turns to the transverse position and the blade 35 is converted to a transverse state and can be used as a transverse scraper.

[0060] Specifically, such as Figure 2 As shown, the tool holder 30 is in the retracted position longitudinally, the second connecting section 2112 of the push button bracket 211 is located in the rightmost positioning area 2212 of the positioning member 22, the driving member 23 is located on the rightmost side, the first guide 311 of the tool holder 30 is connected to the first connecting hole 233 at the front end of the driving member 23, the second guide 321 of the tool holder 30 is located in the right side area of ​​the straight section 1211 of the second guide rail 121, and the blade 35 is completely housed in the receiving cavity 13.

[0061] like Figure 4 As shown, pressing the push button assembly 21 causes the second connecting section 2112 of the push button bracket 211 to separate from the positioning area 2212 of the positioning groove 221 of the positioning member 22. The first connecting section 2111 and the moving area 2211 then cooperate, allowing the push button assembly 21 to drive the driving member 23 to move forward along the first guide rail 222. The first guide member 311 of the tool holder 30, connected to the first connecting hole 233, also moves forward along the first guide rail 222. The second guide member 321 of the tool holder 30 moves forward along the axis. The direction moves forward to the middle area of ​​the straight section 1211 of the second guide rail 121, so that the blade holder 30 moves forward along the axial direction to the first longitudinal position; the push button assembly 21 is released, the push button spring 212 causes the push button bracket 211 to move outward, the second connecting section 2112 of the push button bracket 211 cooperates with the second positioning area 2212 from the right to lock the blade holder 30 in the first longitudinal position, and a part of the triangular tip of one end of the blade 35 protrudes from the blade housing 10, so that it can be used as a cutting knife.

[0062] like Figure 6 As shown, pressing the push button assembly 21 causes the second connecting section 2112 of the push button bracket 211 to separate from the positioning area 2212 of the positioning groove 221 of the positioning member 22. The first connecting section 2111 and the moving area 2211 then cooperate, allowing the push button assembly 21 to drive the driving member 23 to move forward along the direction of the first guide rail 222. The first guide member 311 of the tool holder 30, hinged to the first connecting hole 233, also moves forward along the direction of the first guide rail 222. The second guide member 321 of the tool holder 30 moves forward along the direction of the first guide rail 222. The blade holder 30 moves forward along the axis to the left side of the straight section 1211 of the second guide rail 121, causing the blade holder 30 to move forward along the axis to the second longitudinal position. The push button assembly 21 is released, and the push button spring 212 causes the push button bracket 211 to move outward. The second connecting section 2112 of the push button bracket 211 cooperates with the third positioning area 2212 from the right to lock the blade holder 30 in the second longitudinal position. The triangular tip of one end of the blade 35 protrudes from the blade housing 10 and can be used as a cutting knife.

[0063] like Figure 8 As shown, pressing the push button assembly 21 causes the second connecting section 2112 of the push button bracket 211 to separate from the positioning area 2212 of the positioning groove 221 of the positioning member 22. The first connecting section 2111 and the moving area 2211 then cooperate, allowing the push button assembly 21 to drive the driving member 23 to move forward along the first guide rail 222. The first guide member 311 of the tool holder 30, hinged to the first connecting hole 233, also moves forward along the first guide rail 222. The second guide member 321 of the tool holder 30 then rotates and moves to the second... The middle area of ​​the main support section 1212 of the guide rail 121 allows the blade holder 30 to move forward along the axial direction while rotating counterclockwise to the transition position. Releasing the push button assembly 21 causes the push button spring 212 to move the push button bracket 211 outwards. The second connecting section 2112 of the push button bracket 211 cooperates with the second positioning area 2212 from the left, locking the blade holder 30 in the transition position. The cutting edge of the blade 35 is fully exposed in the blade housing 10 and forms a 45° angle with the blade housing 10, allowing it to be used as a slanted scraper. Furthermore, the blade housing 10 is provided with a clearance area 131, located on one or both sides of the front end of the blade housing 10. The clearance area 131 laterally connects the receiving cavity 13 to the outside. When the blade holder 30 rotates, the clearance area 131 is suitable for the blade holder 30 to rotate out of or into the receiving cavity 13, thereby preventing interference between the blade 35 and the blade housing 10.

[0064] like Figure 10As shown, pressing the push button assembly 21 causes the second connecting section 2112 of the push button bracket 211 to separate from the positioning area 2212 of the positioning groove 221 of the positioning member 22. The first connecting section 2111 and the moving area 2211 then cooperate, allowing the push button assembly 21 to drive the driving member 23 to move forward along the first guide rail 222. The first guide member 311 of the tool holder 30, hinged to the first connecting hole 233, also moves forward along the first guide rail 222. The second guide member 321 of the tool holder 30 then rotates and moves to the first connecting hole 233. The end region of the main support section 1212 of the second guide rail 121 allows the blade holder 30 to move forward along the axial direction while rotating counterclockwise to a lateral position. Releasing the push button assembly 21 causes the push button spring 212 to move the push button bracket 211 outwards. The second connecting section 2112 of the push button bracket 211 engages with the leftmost positioning area 2212, locking the blade holder 30 in the lateral position. The cutting edge of the blade 35 is fully exposed in the blade housing 10, forming a 90° angle with it, allowing it to be used as a lateral scraper. It is understood that by further extending the second guide rail 121, the blade holder 30 can continue to translate and or rotate, allowing the cutting edge of the blade 35 to form an angle of 135° or even 180° with the blade housing 10, or any angle between 90° and 180°.

[0065] In some embodiments, such as Figure 16 and Figure 17 As shown, the tool holder 30 includes a first tool post 31, an intermediate tool post 33, and a second tool post 32. The intermediate tool post 33 elastically connects the first tool post 31 and the second tool post 32. The first guide member 311 protrudes radially outward from the first tool post 31 and is pivotally connected to the first connecting hole 233 at the front end of the drive member 23. It can move along the first guide rail 222 through the drive member 23. The second guide member 321 protrudes radially outward from the second tool post 32 relative to the first guide member 311 and is connected to the second guide rail 121 of the lower shell 12. The blade 35 is detachably installed between the second guide member 321 and the intermediate tool post 33.

[0066] In some embodiments, such as Figure 16 and Figure 17 As shown, the tool holder 30 also includes a spring piece 34. The first tool holder 31 has a spring piece groove 312 for mounting the spring piece 34 on the side facing the second tool holder 32, and a first mounting groove 313 for accommodating the intermediate tool holder 33. The spring piece 34 is installed between the first tool holder 31 and the intermediate tool holder 33, so as to provide the intermediate tool holder 33 with a force against the second tool holder 32, so that the blade 35 is clamped between the intermediate tool holder 33 and the second tool holder 32.

[0067] Furthermore, the blade 35 is provided with a through-hole limiting opening 352 and a mounting hole 351. The main body 333 of the intermediate tool holder 33 is housed in the first mounting groove 313. The main body 333 is provided with a limiting part 334 and a fixing part 332 protruding on the side facing the second tool holder 32. The limiting part 334 is adapted to cooperate with the limiting opening 352, and the fixing part 332 is adapted to pass through the mounting hole 351 to fix the blade 35. The second tool holder 32 is provided with a second mounting groove 322 on the side facing the intermediate tool holder 33. The second mounting groove 322 is used to accommodate the end of the fixing part 332.

[0068] In some embodiments, such as Figure 11 As shown, the deformable cutting tool also includes a tool changing assembly 40 for changing the blade 35. The tool changing assembly 40 includes a tool changing button 42 and a return spring 41. The return spring 41 allows the tool changing button 42 to be movably mounted on the lower housing 12. The tool changing button 42 has a protruding part 421 protruding from the side facing the tool holder 30. The second tool holder 32 also has a through tool changing hole 323. The main body 333 of the intermediate tool holder 33 also has an extension 331 protruding from the side facing the second tool holder 32. The extension 331 extends into the tool changing hole 323. When the tool holder 30 is in the second longitudinal position, the protruding part 421 is aligned with the tool changing hole 323 and abuts against the extension 331. Pressing the tool changing button 42 causes the intermediate tool holder 33 to move towards the first tool holder 31, so that the fixing part 332 and the mounting hole 351 are separated, and the blade 35 can be changed.

[0069] Specifically, when the tool holder 30 moves to Figure 5 and Figure 6 When the tool changer is in the position shown, i.e., in the second longitudinal position, the tool changer hole 323 on the second tool holder 32 is aligned with the protrusion 421 of the tool changer button 42. When the tool changer button 42 is pressed, the protrusion 421 pushes against the extension 331 of the intermediate tool holder 33 through the tool changer hole 323, pushing the intermediate tool holder 33 towards the first mounting groove 313 of the first tool holder 31. The fixing part 332 of the intermediate tool holder 33 disengages from the second mounting groove 322 of the second tool holder 32, and the fixing part 332 further separates from the mounting hole 351 of the blade 35, allowing the blade 35 to be removed. When the tool changer button 42 is released, the return spring 41 pushes the tool changer button 42 outward. Under the action of the spring piece 34, the intermediate tool holder 33 pushes against the second tool holder 32, and the fixing part 332 of the intermediate tool holder 33 passes through the mounting hole 351 of the blade 35 and inserts into the second mounting groove 322 of the second tool holder 32, thereby fixing the blade 35. In other words, the blade holder 30 can quickly replace the blade 35 via the blade change button 42, which is simple and convenient to operate, allowing for quick and safe replacement of the blade 35.

[0070] In some embodiments, the tail end of the blade 10 has a curved hook portion 60 for prying open objects, such as the lid of a paint can.
