[0001] The present invention relates to the technical field of cutting tools, in particular to a deformable cutting tool. Background Art
[0002] Knives are mainly divided into cutting knives for side cutting and scrapers for scraping. A cutting knife is a tool for arts and crafts, mostly of a pull-out structure, consisting of a plastic handle and a blade. Usually the cutting edge of the blade is parallel to the axis of the handle or the shell, and is mainly used for cutting, such as cutting paper, cardboard, etc. Scrapers usually have a blade that is perpendicular or orthogonal to the axis of the handle and are used for scraping, such as scraping paint, glue marks, etc. from a flat surface. Cutting knives and scrapers are two separate hand tools and are often not interchangeable. It is usually necessary to purchase, store and carry these two separate tools, which brings inconvenience to users.
[0003] Although existing deformable cutting tools can be switched between cutting blade and scraper forms, they have a complex structure and are inconvenient to operate.

[0052] It should be noted that the terms "front", "back", etc. are used to indicate directions to facilitate the description of the present invention and simplify the description, rather than to indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. It can also be expressed as "above", "below", or "one side", "the other side", etc., and cannot be understood as limiting the specific scope of protection of the present invention.
[0053] A deformable tool, as shown in Figures 1 to 11, includes: a knife housing 10, a knife seat 30, a first guide assembly and a second guide assembly. The knife housing 10 is provided with a receiving cavity 13 and a port 14. The port 14 is opened at the front end of the knife housing 10 so that the receiving cavity 13 is connected to the outside world; the knife seat 30 is used to carry a blade 35. The knife seat 30 is rotatably installed in the receiving cavity 13 and can extend out of the receiving cavity 13 or retract into the receiving cavity 13 through the port 14; the first guide assembly is provided with a first guide rail 222 and a driving member 23. The driving member 23 can drive The front surface of the knife holder 30 is movably connected to the front surface of the knife holder 30, so that the knife holder 30 can move along the first guide rail 222. That is, the driving member 23 is pivotally connected to the front surface of the knife 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 knife holder 30 can move along the first guide rail 222. The second guide assembly is provided with a fixed surface 122 and a second guide rail 121. The second guide rail 121 is opened on the fixed surface 122. The back surface of the knife holder 30 is pivotally connected to the second guide rail 121, so that the knife holder 30 can move along the second guide rail 121. It can be understood that the knife holder 30 is connected to both the driving member 23 and the second guide rail 121, so that it can move along 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 knife holder 30 can translate and / or rotate. When the drive member 23 moves longitudinally relative to the fixed surface 122 along the axial direction, the knife holder 30 can selectively rotate into or out of the accommodating cavity 13, allowing the knife holder 30 to alternately switch between a longitudinal position and a transverse position at multiple positioning angles. In other words, through the driving action of the drive member 23 on the knife holder 30, the knife 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 knife, allowing the knife to be converted between a utility knife and a scraper, convenient operation, conducive to improving work efficiency, and compact structure.
[0054] In some embodiments, as shown in Figures 11 and 12, the tool holder 30 includes a first guide member 311 and a second guide member 321. The first guide member 311 and the second guide member 321 are respectively staggeredly arranged on the front and back sides of the tool holder 30. The first guide member 311 protrudes from the front side of the tool holder 30 and is pivotally connected to the driving member 23, so that the first guide member 311 drives the tool holder 30 to translate and / or rotate along the first guide rail 222. The second guide member 321 protrudes from the back side of the tool holder 30 and is pivotally connected to the second guide rail 121, so that the second guide member 321 drives the tool holder 30 to translate and / or rotate along the second guide rail 121, so that the longitudinal driving force of the driving member 23 on the first guide member 311 can be converted into a steering force for multiple positioning angles of the tool holder 30. That is to say, the first guide member 311 is connected to the driving member 23, and the first guide member 311 further cooperates with the first guide rail 222 to move, and the second guide member 321 cooperates with the second guide rail 121 to produce deflection and guidance, further generating a thrust to push the knife holder 30 in the direction of rotation, so that the knife holder 30 rotates to a preset position, meeting the multi-purpose use requirements of the blade 35 in the longitudinal, transverse and oblique directions, and improving the application range of the tool.
[0055] Specifically, as shown in Figures 1 to 10, the projections of the first guide member 311 and the second guide member 321 on the fixed surface 122 do not overlap. When the first guide member 311 moves along the first guide rail 222 and the second guide member 321 moves along the second guide rail 121, the distance between the projections of the first guide member 311 and the second guide member 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 knife holder 30 can be smoothly translated and / or rotated to achieve multi-angle positioning of the knife, realize multiple uses of one knife, and facilitate storage and carrying.
[0056] In some embodiments, as shown in Figures 11 and 12, the driving member 23 is provided with a driving surface 234. The driving surface 234 can be equipped with a sliding member 50 or directly serve as the sliding member 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 the sliding member 50, in an optional embodiment, as shown in Figure 2, the first guide member 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 member 311 to move along the first guide rail 222, while the second guide member 321 moves along the second guide rail 121, further enabling the tool holder 30 to smoothly translate and / or rotate to achieve multi-angle positioning of the tool. When the slide 50 is assembled on the driving surface 234, in an optional embodiment, as shown in FIG18 , the first guide member 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 slide 50. When the slide 50 moves longitudinally along the axis, it can push the driving surface 234 to translate and / or rotate, further driving the first guide member 311 to move along the first guide rail 222, while the second guide member 321 moves along the second guide rail 121, so that the tool holder 30 can smoothly translate and / or rotate to achieve multi-angle positioning of the tool. It is understood that the first guide member 311 can be connected to the driver 23, and the driver 23 moves along the first guide rail 222, so that the first guide member 311 moves along the first guide rail 222 indirectly. The first guide member 311 can also directly cooperate with the first guide rail 222, and the first guide member 311 can move along the first guide rail 222 under the drive of the driver 23.
[0057] In some embodiments, as shown in Figures 1 to 10, the first guide rail 222 and the second guide rail 121 are linear structures and / or arc-shaped structures, and 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 branch section 1212, and the main branch section 1212 extends outward in 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 dual force of the fixed surface 122 and the driving surface 234, the tool holder 30 gradually rotates out of or back into the accommodating cavity 13 from the port 14. That is to say, when the first guide member 311 moves along the first guide rail 222 and the second guide member 321 moves along the main branch section 1212 of the second guide rail 121, since the distance between the projections of the first guide member 311 and the second guide member 321 on the fixed surface 122 remains unchanged, and the extension direction of the main branch section 1212 deviates from the extension direction of the first guide rail 222, the knife seat 30 changes direction and rotates under the dual action of the fixed surface 122 and the driving surface 234, for example, it rotates out of the accommodating cavity 13 from the port 14 so that the blade is perpendicular to the axis and can be used as a scraper, or it rotates back from the port 14 to the accommodating cavity 13 so that the blade is parallel to the axis and can be used as a cutting knife, or the blade is made at other angles to the axis to realize multi-angle positioning of the tool and achieve multiple uses of one knife.
[0058] Specifically, as shown in Figures 1 to 10, the second guide rail 121 includes a straight section 1211, a main branch section 1212 integrally connected to the straight section 1211, and the main branch section 1212 extends outward in an arc or curve in a direction away 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 blade holder 30 linearly moves along the straight section 1211 of the second guide rail 121 and the first guide rail 222, the blade 35 on the blade holder 30 is retracted into the accommodating cavity 13 or extended out of the port 14. When the blade holder 30 moves along the main branch section 1212 of the second guide rail 121 and the first guide rail 222, the blade 35 on the blade holder 30 is able to change direction at multiple angles between a longitudinal position and a transverse position. In the longitudinal position, the cutting edge of the blade 35 is parallel to the axial direction; in the transverse position, the cutting edge of the blade 35 is perpendicular to the axial direction.
[0059] That is to say, when the first guide member 311 on the knife seat 30 moves along the first guide rail 222 and the second guide member 321 is located in the straight section 1211 of the second guide rail 121, the blade is parallel to the axial direction, and the knife seat 30 moves longitudinally along the axial direction, so that the blade extends from the port 14 to the accommodating cavity 13 or retracts into the accommodating cavity 13; when the first guide member 311 on the knife seat 30 moves along the first guide rail 222 and the second guide member 321 is located in the main branch section 1212 of the second guide rail 121, the knife seat 30 is able to move and change direction, so that the angle between the blade and the axis changes, so as to achieve multi-angle positioning and meet various usage requirements.
[0060] In another optional embodiment, as shown in Figure 18, the first guide rail 222 extends in an arc shape, and the main branch 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 knife holder 30 turns and moves along the main branch section 1212 of the first guide rail 222 and the second guide rail 121, the blade 35 on the knife holder 30 can be changed in direction at multiple positioning angles between the longitudinal position and the transverse position.
[0061] In some embodiments, as shown in Figure 11, the knife housing 10 includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are installed and fixed by fasteners 15. The driving member 23 is located in the accommodating cavity 13 between the upper shell 11 and the lower shell 12, and is arranged between the upper shell 11 and the knife seat 30. The upper shell 11 is provided with an elongated push button groove 111, and the push button groove 111 extends along the axial direction. The fixing surface 122 is located on the inner surface of the lower shell 12, and the second guide rail 121 is formed on the inner surface of the lower shell 12, so as to be pivotally connected to the second guide member 321 on the knife seat 30.
[0062] In some embodiments, as shown in Figures 11 and 12, the deformable tool further includes a moving component 20, the moving component 20 includes a push button component 21 and a positioning member 22, the positioning member 22 is arranged between the push button component 21 and the driving member 23, and the positioning member 22 is provided with a first guide rail 222 and a positioning groove 221. Among them, the first guide rail 222 is formed on the back side of the positioning member 22, and is connected to the driving member 23, and the first guide member 311 is further moved along the direction of the first guide rail 222 through the driving member 23; the positioning groove 221 is opened on the surface of the positioning member 22, and the push button groove 111 of the upper shell 11 is connected to the positioning groove 221 and the outside world. 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, wherein the push button assembly 21 can be elastically locked in the positioning groove 221, so that the blade 35 of the knife seat 30 is locked in the longitudinal position, the transverse position or the directional transition position between the longitudinal position and the transverse position.
[0063] That is, the positioning member 22 is fixed to the upper shell 11. The back of the positioning member 22 is provided with a first guide rail 222, which cooperates with the protruding engagement portions 232 provided on both sides of the driving member 23, allowing the driving member 23 to move along the first guide rail 222. Furthermore, the first guide member 311 on the blade holder 30 is pivotally connected to the first connecting hole 233 at the front end of the driving member 23, allowing the first guide member 311 to move along the first guide rail 222. The inner surface of the lower shell 12 is provided with a second guide rail 121, which is connected to the second guide member 321 on the blade holder. The lower end of the push button assembly 21 passes through the push button slot 111 of the upper shell 11 and the positioning slot 221 of the positioning member 22 and is connected to the rear end of the driving member 23. The push button assembly can push the driving member 23 to move, further allowing the blade holder 30 to translate and / or rotate. Furthermore, the push button assembly 21 can be elastically locked in the positioning slot 221, so that the knife holder 30 is locked in an optional position, so that the blade 35 is located in the longitudinal position, the transverse position, or other optional positions between the longitudinal position and the transverse position, for example, 30°, 45°, or 60° to the axis. Through 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 knife housing 10, the movement path of the knife holder 30 is defined, so that the blade 35 smoothly transitions to multiple positioning positions without the need for adding complex accessories, which is conducive to reducing production costs. In an optional embodiment, the positioning member 22 and the upper shell 11 are integrally formed.
[0064] In some embodiments, as shown in Figures 11 and 12, 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 slot 111 and the positioning slot 221 and is connected to the driving 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 driving member 23, so that the push button bracket 211 can be movably locked in the positioning slot 221. The end of the push button bracket 211 extending outward from the outer side of the upper shell 11 is fixedly connected to the push button panel 213, which is convenient for pushing the push button bracket 211 to make the driving member 23 move along the first guide rail 222.
[0065] Furthermore, the push button bracket 211 includes a first connecting section 2111 and a second connecting section 2112 arranged perpendicular to the driving surface 234. The positioning slot 221 includes an elongated movable region 2211 extending along the axis and a plurality of spaced-apart positioning regions 2212. The first connecting section 2111 passes through the push button slot 111 of the upper housing 11 and is adapted to move along the movable region 2211 of the positioning slot 221. The second connecting section 2112 connects to the second connecting hole 231 of the driving member 23 and is adapted to cooperate with the positioning regions 2212 to lock the driving member 23, thereby maintaining the blade holder 30 in an optional position. In other words, the first connecting section 2111 of the push button bracket 211 is adapted to move along the push button slot 111 of the upper housing 11, and the first connecting section 2111 is also adapted to move along the positioning slot 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 slot 221 to position the blade holder 30 and further position the blade 35 .
[0066] Specifically, when the push button assembly 21 is pressed and pushed, the push button spring 212 is compressed, the push button bracket 211 moves inward, and 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 engage, allowing the push button assembly 21 to drive the driver 23 to move. When 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 engages with the positioning area 2212, locking the driver 23 and further positioning the blade holder 30. The blade holder 30 can be switched and locked in position with a single hand, improving operational convenience and safety. Furthermore, the blade holder 30 can be smoothly moved and turned by the first and second guide rails 222 and 121, making pressing and pushing the push button assembly 21 easier and smoother.
[0067] Furthermore, as shown in Figures 13 to 15, the deformable tool also includes an anti-rotation part 70, which is rotatably connected to the driving part 23 and can move longitudinally in the axial direction together with the driving part 23. One end of the anti-rotation part 70 is movably connected to the push button assembly 21. When the push button assembly 21 moves toward the inside or outside of the knife housing 10 in the direction perpendicular to the fixed surface 122, it can drive the anti-rotation part 70 to rotate relative to the driving part 23. The other end of the anti-rotation part 70 is provided with a stop portion 71 protruding toward one side of the knife seat 30, and the front of the knife seat 30 is provided with a plurality of stop grooves 314 for accommodating the stop portion 71. When the anti-rotation part 70 rotates under the action of the push button assembly 21, the stop portion 71 is engaged with or separated from the stop groove 314. It is understood that when the push button assembly 21 is pressed, the push button assembly 21 moves toward the inside of the blade housing 10, driving the anti-rotation member 70 to rotate, causing the stop portion 71 to separate from the stop groove 314, and allowing the blade holder 30 to rotate relative to the drive member 23; when the push button assembly 21 is released, the push button assembly 21 moves toward the outside of the blade housing 10, driving the anti-rotation member 70 to rotate, causing the stop portion 71 to engage with the stop groove 314, and the blade holder 30 to be locked with the drive member 23, so that the blade holder 30 remains in the longitudinal position, the transverse position, or other optional position between the longitudinal position and the transverse position. In other words, under the dual action of the push button assembly 21 and the positioning groove 221, and the anti-rotation member 70 and the blade holder 30, the position of the blade holder 30 is locked, thereby improving the reliability and safety of the deformable knife during use. In another optional embodiment, an anti-rotation spring is provided below the anti-rotation member 70 on one side close to the push button assembly 21. The anti-rotation spring provides torque to the anti-rotation member 70 so that the stop portion 71 on the other side of the anti-rotation member 70 moves downward and engages with the stop groove 314.
[0068] In some embodiments, as shown in Figures 1 to 10, the straight section 1211 of the second guide rail 121 and the first guide rail 222 coincide with each other in a direction perpendicular to the axis, and the main branch section 1212 extends radially outward in an arc shape from the front end of the straight section 1211. When the driving member 23 moves along the first guide rail 222, the knife holder 30 is moved along the second guide rail 121 to the retracted position, the first longitudinal position, the second longitudinal position, the transition position and the transverse 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 knife holder 30 is longitudinally in the retracted position, and the blade 35 is retracted into the accommodating cavity 13. When the second guide member 321 moves along the second longitudinal position, the knife holder 30 is longitudinally in the retracted position, and the blade 35 is retracted into the accommodating cavity 13. When the straight section 1211 of the guide rail 121 moves forward, the knife holder 30 is successively 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 completely extends out of the port 14. When the second guide member 321 moves from the straight section 1211 to the main branch section 1212, the knife holder 30 turns to the transition position, the knife holder 30 rotates out of the accommodating cavity 13 and the turning angle is generally 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 member 321 moves to the end of the main branch section 1212, the knife holder 30 turns to the horizontal position, and the blade 35 is converted to a horizontal state, and can be used as a horizontal scraper.

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 second positioning area 2212 from the right to lock the knife holder 30 in the first longitudinal position. A part of the triangular tip of one end of the blade 35 is exposed from the knife housing 10, so that it can be used as a cutting knife.
[0071] As shown in FIG6 , by pressing the push button assembly 21, the second connecting section 2112 of the push button bracket 211 is separated from the positioning area 2212 of the positioning groove 221 of the positioning member 22, and the first connecting section 2111 cooperates with the moving area 2211, so that the push button assembly 21 can drive the driving member 23 to move forward along the first guide rail 222; the first guide member 311 of the knife holder 30 is hinged to the first connecting hole 233 and also moves forward along the first guide rail 222, and the second guide 321 of the knife holder 30 Move forward along the axial direction to the left area of the straight section 1211 of the second guide rail 121, so that the knife holder 30 moves forward along the axial direction to the second longitudinal position; release the push button assembly 21, the push button spring 212 causes the push button bracket 211 to move outward, and the second connecting section 2112 of the push button bracket 211 cooperates with the third positioning area 2212 from the right to lock the knife holder 30 in the second longitudinal position, and the triangular tip at one end of the blade 35 is exposed from the knife housing 10, so that it can be used as a cutting knife.
[0072] As shown in FIG8 , by pressing the push button assembly 21, the second connecting section 2112 of the push button bracket 211 is separated from the positioning area 2212 of the positioning groove 221 of the positioning member 22, and the first connecting section 2111 cooperates with the moving area 2211, so that the push button assembly 21 can drive the driving member 23 to move forward along the first guide rail 222; the first guide member 311 of the knife holder 30 is hinged to the first connecting hole 233 and also moves forward along the first guide rail 222; the second guide 321 of the knife holder 30 turns and moves to the first guide rail 222; The middle area of the main branch section 1212 of the second guide rail 121 causes the knife holder 30 to move forward along the axis direction while rotating counterclockwise to the transition position; when the push button assembly 21 is released, the push button spring 212 causes the push button bracket 211 to move outward, and the second connecting section 2112 of the push button bracket 211 cooperates with the second positioning area 2212 from the left to lock the knife holder 30 in the transition position. The blade 35 is completely exposed to the knife housing 10 and forms a 45° angle with the knife housing 10, so that it can be used as an oblique scraper. Furthermore, the knife housing 10 is provided with an avoidance area 131. The avoidance area 131 is located on one side or both sides of the front end of the knife housing 10. The avoidance area 131 laterally connects the accommodating chamber 13 and the outside world. When the knife holder 30 rotates, the avoidance area 131 is suitable for the knife holder 30 to rotate out of or into the accommodating chamber 13, thereby avoiding interference between the blade 35 and the knife housing 10.
[0073] As shown in FIG10 , by pressing the push button assembly 21, the second connecting section 2112 of the push button bracket 211 is separated from the positioning area 2212 of the positioning groove 221 of the positioning member 22, and the first connecting section 2111 cooperates with the moving area 2211, so that the push button assembly 21 can drive the driving member 23 to move forward along the first guide rail 222; the first guide member 311 of the knife holder 30 is hinged to the first connecting hole 233 and also moves forward along the first guide rail 222; the second guide 321 of the knife holder 30 turns and moves The blade holder 30 is moved forward along the axis and rotated counterclockwise to the horizontal position at the same time as the main branch section 1212 of the second guide rail 121 is reached. 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 leftmost positioning area 2212 to lock the blade holder 30 in the horizontal position. The cutting edge of the blade 35 is completely exposed from the blade housing 10 and forms a 90° angle with the blade housing 10, allowing it to be used as a horizontal scraper. It is understood that further extending the second guide rail 121 allows the blade holder 30 to continue to translate and / or rotate, so that the cutting edge of the blade 35 forms an angle of 135° or even 180° with the blade housing 10, or any angle between 90° and 180°.
[0074] In some embodiments, as shown in Figures 16 and 17, the tool holder 30 includes a first tool holder 31, an intermediate tool holder 33 and a second tool holder 32. The intermediate tool holder 33 elastically connects the first tool holder 31 and the second tool holder 32. The first guide member 311 protrudes radially outward from the first tool holder 31 and is pivotally connected to the first connecting hole 233 at the front end of the driving member 23. It is able to move along the first guide rail 222 through the driving member 23. The second guide member 321 protrudes radially outward from the second tool holder 32 eccentrically 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 holder 33.
[0075] In some embodiments, as shown in Figures 16 and 17, the tool holder 30 also includes a spring clip 34. A spring clip groove 312 for installing the spring clip 34 and a first installation groove 313 for accommodating the intermediate tool holder 33 are provided on the side of the first tool holder 31 facing the second tool holder 32. The spring clip 34 is installed between the first tool holder 31 and the intermediate tool holder 33 to provide a force to the intermediate tool holder 33 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.
[0076] Furthermore, the blade 35 is provided with a through-limiting opening 352 and a mounting hole 351, and the main body 333 of the intermediate blade holder 33 is accommodated in the first mounting groove 313. The main body 333 is protrudingly provided with a limiting portion 334 and a fixing portion 332 on the side facing the second blade holder 32. The limiting portion 334 is suitable for cooperating with the limiting opening 352, and the fixing portion 332 is suitable for passing through the mounting hole 351 to fix the blade 35. The second blade holder 32 is provided with a second mounting groove 322 on the side facing the intermediate blade holder 33. The second mounting groove 322 is used to accommodate the end of the fixing portion 332.
[0077] In some embodiments, as shown in Figure 11, the deformable tool also includes a tool changing assembly 40 for replacing the blade 35. The tool changing assembly 40 includes a tool changing button 42 and a return spring 41. The return spring 41 enables the tool changing button 42 to be press-disposed on the lower shell 12. The tool changing button 42 is provided with a protrusion 421 protruding toward the side of the tool holder 30; the second tool holder 32 is also provided with a penetrating tool changing hole 323, and the main body 333 of the intermediate tool holder 33 is also provided with an extension portion 331 protruding toward the side of the second tool holder 32. The extension portion 331 extends into the tool changing hole 323. When the tool holder 30 is in the second longitudinal position, the protrusion is aligned with the tool changing hole 323 so as to be against the extension portion 331. Pressing the tool changing button 42 causes the intermediate tool holder 33 to move toward the side of the first tool holder 31 to separate the fixing portion 332 and the mounting hole 351, so that the blade 35 can be replaced.
[0078] Specifically, when the tool holder 30 moves to the position shown in Figures 5 and 6, that is, when it is located in the second longitudinal position, the tool change hole 323 on the second tool holder 32 is aligned with the protrusion 421 of the tool change button 42. When the tool change button 42 is pressed, the protrusion 421 presses against the extension 331 of the intermediate tool holder 33 through the tool change hole 323, pushing the intermediate tool holder 33 toward the first mounting groove 313 of the first tool holder 31, and the fixing portion 332 of the intermediate tool holder 33 is released from the second tool holder 32. The second mounting slot 322 of the intermediate blade holder 33 is disengaged, and the fixing portion 332 is further separated from the mounting hole 351 of the blade 35, allowing the blade 35 to be removed. When the blade-changing button 42 is released, the return spring 41 pushes the blade-changing button 42 outward. Under the action of the spring 34, the intermediate blade holder 33 is pushed toward the second blade holder 32. The fixing portion 332 of the intermediate blade holder 33 passes through the mounting hole 351 of the blade 35 and is inserted into the second mounting slot 322 of the second blade holder 32, thereby fixing the blade 35. In other words, the blade holder 30 can quickly replace the blade 35 by using the blade-changing button 42. The operation is simple and convenient, and the blade 35 can be replaced quickly and safely.
[0079] In some embodiments, the rear end of the blade housing 10 has a curved hook portion 60 for prying objects, such as for prying open the lid of a paint bucket.
[0080] A deformable folding knife, as shown in Figures 19 to 25, comprises: a knife housing 10, a knife holder 40, a first guide assembly, and a second guide assembly. The knife housing 10 comprises an outer shell 11 and an inner shell 20. The outer shell 11 is provided with a main accommodating chamber 12 and an opening 13. The opening 13 is provided on the side of the outer shell 11, allowing the main accommodating chamber 12 to communicate with the outside world. The inner shell 20 is rotatably and foldably mounted to the main accommodating chamber 12 via a main shaft 14, and can be rotated out of or into the main accommodating chamber 12 through the opening 13. The inner shell 20 is provided with an accommodating chamber 23 and a port 24. The port 24 is provided at the front end of the inner shell 20, allowing the accommodating chamber 23 to communicate with the outside world. The knife holder 40 is used to carry a blade 45. The knife holder 40 is rotatably mounted to the accommodating chamber 23, and can be rotated out of or into the accommodating chamber 23 through the port 24. The inner shell 20 is further provided with an escape area 231, which is located on one or both sides of the front end of the inner shell 20. The escape area 231 laterally connects the accommodating chamber 23 with the outside world. When the knife holder 40 rotates, the escape area 231 is suitable for the knife holder 40 to rotate out of or into the accommodating chamber 23, thereby preventing interference between the blade 45 and the inner shell 20. Specifically, when the inner shell 20 rotates out of the main accommodating chamber 12, the knife is in an unfolded state, the cutting edge of the blade 45 extends from the accommodating chamber 23 through the port 24, and the blade 45 can be rotated in a direction by the knife holder 40, realizing multi-angle positioning and use. When the inner shell 20 rotates into the main accommodating chamber 12, the knife is in a folded state, and the blade 45 and the inner shell 20 are accommodated in the main accommodating chamber 12, thereby preventing accidental injury caused by the exposure of the blade 45. At the same time, it helps to reduce the length of the knife, making it easier to carry.
[0081] As shown in Figures 26 to 28, the first guide assembly is provided with a first guide rail 212 and a driving member 30. The driving member 30 is drivably connected to the front face of the tool holder 40 so that the tool holder 40 can move along the first guide rail 212. That is, the driving member 30 is pivotally connected to the front face of the tool holder 40, and the driving member 30 can drive the tool holder 40 to move along the first guide rail 212 by translating and / or rotating the driving member 30. The second guide assembly is provided with a fixed surface 222 and a second guide rail 221. The second guide rail 221 is opened on the fixed surface 222, and the back face of the tool holder 40 is pivotally connected to the second guide rail 221 so that the tool holder 40 can move along the second guide rail 221.
[0082] It will be appreciated that the blade holder 40 is connected to both the first guide rail 212 and the second guide rail 221, allowing it to move along the first guide rail 212 and the second guide rail 221. The blade holder 40 is guided by the first guide rail 212 and the second guide rail 221, allowing it to translate and / or rotate. In other words, when the drive member 30 translates and / or rotates relative to the fixed surface 222, the blade holder 40 can selectively rotate into or out of the accommodating cavity 23, allowing the blade holder 40 to alternately switch between longitudinal and transverse positions at multiple angles, allowing the blade to be used as a cutter or scraper, which facilitates operation, improves work efficiency, and has a compact structure.
[0083] In some embodiments, as shown in Figures 25 to 28, the deformable folding knife further includes a sliding assembly 50. The driving member 30 is provided with a driving surface 34. The sliding assembly 50 is assembled on the driving surface 34 to drive the driving member 30 to translate and / or rotate. Specifically, by pushing the sliding assembly 50 to move longitudinally along the axis, the driving member 30 is driven to translate and / or rotate, which in turn drives the blade holder 40 to translate and / or rotate. In addition, the blade holder 40 is rotated out of or into the accommodating cavity 23 to achieve multi-angle steering.
[0084] Specifically, as shown in Figures 25 and 26, the blade holder 40 includes a first guide member 411 and a second guide member 421. The first guide member 411 and the second guide member 421 are staggeredly disposed on the front and back sides of the blade holder 40, respectively. The first guide member 411 protrudes from the front side of the blade holder 40 and is pivotally connected to the front end of the drive surface 34 and the first guide rail 212, thereby enabling the first guide member 411 to drive the blade holder 40 to translate and / or rotate along the first guide rail 212. The second guide member 421 protrudes from the back side of the blade holder 40 and is pivotally connected to the second guide rail 221, thereby enabling the second guide member 421 to drive the blade holder 40 to translate and / or rotate along the second guide rail 221, thereby converting the longitudinal driving force of the sliding assembly 50 on the driving member 30 into a steering force for the driving member 30 to apply to the blade holder 40 at multiple positioning angles.
[0085] That is to say, the first guide member 411 is pivotally connected to the driving member 30, so that the knife holder 40 can move under the driving action of the driving member 30, and the first guide member 411 is pivotally connected to the first guide rail 212 for coordinated movement, and the second guide member 421 is coordinated with the second guide rail 221 for movement to generate deflection and guidance, further generating a thrust to push the knife holder 40 in the direction of rotation, so that the knife holder 40 rotates to a preset position to meet the multi-purpose use requirements of the blade 45 in the longitudinal, transverse and oblique directions, thereby improving the application range of the tool.
[0086] Specifically, a first connecting hole 33 is provided at the front end of the driving member 30, and a second connecting hole 31 is provided at the rear end of the driving member 30. The first guide member 411 on the tool holder 40 is pivotally connected to the first connecting hole 33, and the sliding assembly 50 is pivotally connected to the second connecting hole 31. When the sliding member of the sliding assembly 50 is pushed to move longitudinally along the axial direction, the driving member 30 is pushed to translate and / or rotate, and the first guide member 411 is further driven to move along the first guide rail 212, and the second guide member 421 moves along the second guide rail 221, so that the tool holder 40 can smoothly translate and / or rotate along the accommodating cavity 23 to achieve multi-angle positioning of the tool.
[0087] In some embodiments, as shown in Figures 33 to 36, the first guide rail 212 and the second guide rail 221 are arc-shaped structures with different trajectories. The first guide rail 212 extends forward in a direction deviating from the second guide rail 221, and the second guide rail 221 extends outward in a direction deviating from the first guide rail 212, so that the knife seat 40 gradually changes direction and turns under the action of forces in two different directions, gradually turning out of or back to the accommodating cavity 23 from the port 24, so that the blade 45 on the knife seat 40 can change direction at multiple positioning angles between the longitudinal position and the lateral position.
[0088] Specifically, since the projections of the first guide member 411 and the second guide member 421 on the fixed surface 222 do not overlap, and the distance between the projections of the first guide member 411 and the second guide member 421 on the fixed surface 222 remains unchanged, when the extension direction of the first guide rail 212 and the extension direction of the second guide rail 221 deviate from each other, and the first guide member 411 moves along the first guide rail 212 and the second guide member 421 moves along the second guide rail 221, under the guidance of the first guide rail 212 and the second guide rail 221, the relative positions of the first guide member 411 and the second guide member 421 on the fixed surface 222 change, further enabling the knife holder 40 to smoothly translate and / or rotate, so as to realize multi-angle positioning of the tool, realize multiple uses of one knife, and facilitate storage and carrying.
[0089] In some embodiments, as shown in Figures 25 to 28, the inner housing 20 includes an upper housing 21 and a lower housing 22, which are fixed together by fasteners 25. The driving member 30 is accommodated in the accommodating cavity 23 between the upper housing 21 and the lower housing 22, and is located between the upper housing 21 and the blade holder 40. The upper housing 21 is provided with a first guide rail 212 and a positioning groove 211. The first guide rail 212 is formed on the inner surface of the upper housing 21 and is pivotally connected to the first guide member 411 on the blade holder 40. The positioning groove 211 is formed on the surface of the upper housing 21 and extends in the axial direction. The driving member 30 can be elastically locked in the positioning groove 211, so that the blade 45 of the blade holder 40 is locked in a longitudinal position, a transverse position, or a transitional position between the longitudinal and transverse positions, for example, at an angle of 30°, 45°, or 60° to the axis. The fixing surface 222 is located on the surface of the lower shell 22. The second guide rail 221 is formed on the surface of the lower shell 22 and is pivotally connected to the second guide member 421 on the blade holder 40. In other words, the blade holder 40 is movably connected to the upper shell 21 and the lower shell 22 via the first guide member 411 and the second guide member 421. The first guide rail 212 on the back of the upper shell 21 and the second guide rail 221 on the surface of the lower shell 22 jointly define the movement path of the blade holder 40, allowing the blade 45 to smoothly transition to multiple positioning positions without the need for additional complex accessories, which helps reduce production costs.
[0090] In some embodiments, as shown in Figures 26 to 29, the lower end of the sliding assembly 50 passes through the positioning slot 211 and is pivotally connected to the driver 30. The sliding assembly 50 is adapted to move along the positioning slot 211. Further, by pushing the sliding assembly 50, the driver 30 is driven to drive the knife holder 40 to translate and / or rotate. Specifically, the sliding assembly 50 includes a sliding bracket 51 and a sliding spring 52. The sliding bracket 51 passes through the positioning slot 211 and is pivotally connected to the second connection hole 31 of the driver 30. The sliding spring 52 is connected to the sliding bracket 51 and abuts between the driver 30 and the lower shell 22. By pressing the sliding bracket 51, the driver 30 can be movably locked in the positioning slot 211. The end of the sliding bracket 51 extending outside the upper shell 21 is provided with a sliding panel 512 to facilitate pushing the sliding assembly 50 to move along the positioning slot 211.
[0091] Further, in combination with Figures 33 to 36, the positioning groove 211 includes an elongated moving area 2111 extending longitudinally along the axial direction and a plurality of spaced positioning areas 2112. The sliding bracket 51 is provided with an elongated matching portion 511 on the side facing the driving member 30. The matching portion 511 is suitable for moving along the moving area 2111 of the positioning groove 211. The driving member 30 is protrudingly provided with a positioning portion 32 on the side facing the positioning groove 211. The positioning portion 32 is suitable for matching with the positioning area 2112 to lock the driving member 30 so that the tool holder 40 remains in an optional position.
[0092] That is, the engaging portion 511 of the sliding bracket 51 is adapted to move along the movable region 2111 of the positioning slot 211, and the positioning portion 32 of the driving member 30 is adapted to detachably engage with the positioning region 2112 of the positioning slot 211 to position the blade holder 40, and further, to position the blade 45. In an alternative embodiment, the positioning portion 32 is concentrically disposed with the second connecting hole 31, making the structure more compact and easier to operate.
[0093] Specifically, by pressing and pushing the sliding bracket 51, the sliding spring 52 is compressed, causing the sliding bracket 51 and the driver 30 to move inward. The positioning portion 32 of the driver 30 separates from the positioning area 2112 of the positioning slot 211 of the upper shell 21. The mating portion 511 of the sliding bracket 51 cooperates with the moving area 2111 of the positioning slot 211 to move, allowing the sliding assembly 50 to drive the driver 30 to translate and / or rotate. By releasing the sliding bracket 51, the sliding spring 52 causes the sliding bracket 51 and the driver 30 to move outward. The mating portion 511 of the sliding bracket 51 separates from the moving area 2111 of the positioning slot 211. The positioning portion 32 of the driver 30 cooperates with the positioning area 2112, locking the driver 30 and further positioning the blade holder 40. The position of the knife holder 40 can be converted and locked by single-handed operation, which improves the convenience and safety of operation. Through the first guide rail 212 and the second guide rail 221, the knife holder 40 can move and turn smoothly, making it easier and smoother to press and push the sliding component 50.
[0094] In some embodiments, as shown in Figures 28 to 30, the deformable folding knife further includes a safety assembly 60, which includes a safety push button 61, a safety spring 64, and a retaining member 621. The safety push button 61 is longitudinally movably disposed on the side of the upper shell 21 for stopping the blade 45. The safety spring 64 extends longitudinally along the axial direction and abuts against the safety push button 61, so that when the knife holder 40 leaves the longitudinal position, the front end of the safety push button 61 abuts against the knife holder 40 to avoid the blade 45. When the knife holder 40 returns to the longitudinal position, the safety push button 61 is reset to stop the blade 45. A locking groove 612 is provided on the upper side surface of the safety push button 61, and a locking member 621 is arranged on the inner surface of the upper shell 21 and can be elastically rotatably pressed against the driving member 30. The locking member 621 is suitable for being detachably engaged with the locking groove 612. When the knife seat 40 is in the longitudinal position, the locking member 621 is suitable for being engaged with the locking groove 612, and the safety push button 61 avoids the blade 45, so that the blade 45 is rotated out of the accommodating cavity 23. When the knife seat 40 leaves the longitudinal position, the locking member 621 is separated from the locking groove 612 under the action of the driving member 30, so that the front end of the safety push button 61 is pressed against the knife seat 40.
[0095] Specifically, the safety push button 61 includes a base 611, a guide groove 613, a bent portion 614 and a stop portion 615. The guide groove 613 is opened at the base 611 to accommodate the safety spring 64 and is suitable for cooperating with the guide member 63, so that the base 611 is accommodated in the accommodating cavity 23 along the longitudinal movement of the guide member 63. The upper side surface of the base 611 is provided with a locking groove 612 and a long locking groove 617 at intervals. The locking member 621 is rotatably pressed against the driving member 30 and is suitable for moving along the long locking groove 617 or being clamped in the locking groove 612. The bent portion 614 extends from the base 611 to the outside of the inner shell 20 and is exposed on the outside of the inner shell 20 so as to be pushed. The movable bending portion 614 enables the safety push button 61 to move along the guide member 63, and a sliding groove 616 is formed between the base 611 and the bending portion 614, so that it can be movably connected to the upper shell 21. The stop portion 615 extends from the base 611 toward the avoidance area 231, so as to cover at least part of the avoidance area 231. When the blade 45 is in the longitudinal position, the stop portion 615 is located below the blade 45, so as to stop the blade 45 from rotating out of the accommodating cavity 23. When the locking member 621 engages with the locking groove 612 or the front end of the safety push button 61 abuts against the blade seat 40, the safety push button 61 moves so that the stop portion 615 avoids the blade 45, so that the blade 45 can be rotated out of or into the accommodating cavity 23.
[0096] In a specific embodiment, the first guide members 411 and the second guide members 421 on both sides of the knife seat 40 are located on the same straight line parallel to the blade, the starting end of the first guide rail 212 and the starting end of the second guide rail 221 are located on the same straight line parallel to the axis, the first guide rail 212 extends forward in a direction deviating from the second guide rail 221, and the second guide rail 221 extends outward in a direction away from the first guide rail 212, and the end of the first guide rail 212 and the end of the second guide rail 221 are located on the same straight line perpendicular to the axis. When the first guide member 411 is located at the starting end of the first guide rail 212 and the second guide member 421 is located at the second guide rail 2 21, the knife holder 40 is in the longitudinal position, and the blade 45 extends out of the port 24, so that it can be used as a longitudinal cutting knife. When the first guide member 411 turns and moves along the first guide rail 212 and the second guide member 421 turns and moves along the second guide rail 221, the knife holder 40 turns out of the accommodating cavity 23 and the turning angle is generally 0°~90° or 90°~180°. At this time, the blade 45 is converted to an inclined state. When the first guide member 411 is located at the end of the first guide rail 212 and the second guide member 421 is located at the end of the second guide rail 221, the knife holder 40 is rotated to the horizontal position, and the blade 45 is converted to a horizontal state, so that it can be used as a horizontal scraper.
[0097] Specifically, as shown in Figure 33, the inner housing 20 is in the expanded position, and the positioning portion 32 of the driver 30 is located in the positioning area 2112 to the right of the positioning groove 211 of the upper housing 21. At this time, the driver 30 is located at the rightmost position. It can be understood that the sliding assembly 50 is also located at the rightmost position. The first guide member 411 of the blade holder 40 is connected to the first connecting hole 33 at the front end of the driver 30. The first guide member 411 of the blade holder 40 is located at the upper right end of the first guide rail 212, and the second guide member 421 of the blade holder 40 is located at the lower right end of the second guide rail 221. The blade holder 40 is in a longitudinal position, so that the cutting edge of the blade 45 is parallel to the axis, allowing it to be used as a cutting knife. At this time, the safety push button 61 is located at the initial position on the far left, one end of the locking member 621 is against the driving member 30, and the other end of the locking member 621 is against the safety push button 61, and the contact point is located on the right side of the long slot 617. The stop portion 615 is located below the blade 45, thereby stopping the blade 45 from rotating.
[0098] As shown in Figure 34, the safety push button 61 is moved to the right. At this time, one end of the locking member 621 is against the driving member 30, and the other end of the locking member 621 is against the safety push button 61, and is engaged with the locking groove 612, so that the stop portion 615 deviates from the blade 45, avoiding interference with the blade 45 when the subsequent knife seat 40 drives the blade 45 to change direction and rotate.
[0099] As shown in FIG35 , the sliding assembly 50 is pressed, so that the positioning portion 32 of the driving member 30 is separated from the positioning area 2112 of the positioning groove 211 of the upper shell 21, and the matching portion 511 of the sliding bracket 51 is matched with the moving area 2111, so that the sliding assembly 50 can drive the driving member 30 to translate and / or rotate, further causing the first guide member 411 of the knife holder 40 to move along the first guide rail 212, and the second guide member 421 of the knife holder 40 to move along the second guide rail 221, so that the first guide 41 1 moves to the middle area of the first guide rail 212, and the second guide member 421 moves to the middle area of the second guide rail 221; the sliding assembly 50 is released, and the sliding spring 52 causes the sliding bracket 51 and the driving member 30 to move outward. The positioning portion 32 of the driving member 30 cooperates with the positioning area 2112 in the middle of the sliding groove 616 of the upper shell 21, locking the knife holder 40 in the transition position. The blade 45 is completely exposed from the inner shell 20 and forms a 45° angle with the knife housing 10, so that it can be used as an oblique scraper.
[0100] It can be understood that when the driving member 30 moves and / or rotates, the locking member 621 rotates counterclockwise in the direction shown in Figure 35 under the action of the driving member 30, so as to be separated from the locking groove 612. Further, the force of the safety spring 64 causes the safety push button 61 to move forward, and the front end of the base 611 of the safety push button 61 abuts against the knife seat 40, so as to avoid the safety push button 61 from being completely reset. At this time, the stop portion 615 is still deviated from the blade 45, so as to avoid interference with the blade 45, thereby ensuring that the knife seat 40 can drive the blade 45 to change direction and rotate smoothly.
[0101] As shown in FIG36 , the sliding assembly 50 is pressed so that the positioning portion 32 of the driving member 30 is separated from the positioning area 2112 of the positioning groove 211 of the upper shell 21, and the matching portion 511 of the sliding bracket 51 is matched with the moving area 2111, so that the sliding assembly 50 can drive the driving member 30 to translate and / or rotate, further causing the first guide member 411 of the knife holder 40 to move along the first guide rail 212, and the second guide member 421 of the knife holder 40 to move along the second guide rail 221, so that the first guide 411 moves The first guide rail 212 is moved to the lower left end of the first guide rail 212, and the second guide member 421 is moved to the upper left end of the second guide rail 221. The sliding assembly 50 is released, and the sliding spring 52 causes the sliding bracket 51 and the driving member 30 to move outward. The positioning portion 32 of the driving member 30 cooperates with the positioning area 2112 on the left side of the sliding groove 616 of the upper shell 21, locking the blade holder 40 in the horizontal position. The cutting edge of the blade 45 is completely exposed from the inner shell 20 and forms a 90° angle with the blade housing 10, allowing it to be used as a horizontal scraper. It is understood that further extending the second guide rail 221 allows the blade holder 40 to continue to translate and / or rotate, so that the cutting edge of the blade 45 forms an angle of 135° or even 180° with the inner shell 20, or any other angle between 90° and 180°.
[0102] It can be understood that when the driving member 30 translates and / or rotates, the force of the safety spring 64 causes the safety push button 61 to move forward, and the front end of the base 611 of the safety push button 61 abuts against the knife seat 40. The locking member 621 rotates clockwise in the direction shown in Figure 36 under the action of the locking spring 622. One end of the locking member 621 abuts against the driving member 30, and the other end abuts against the safety push button 61, and the contact point moves to the right along the long slot 617. The stop portion 615 is still deviated from the blade 45 to avoid interference with the blade 45, so that the knife seat 40 drives the blade 45 to change direction and rotate smoothly. When the knife seat 40 is in the longitudinal position, the safety push button 61 is completely reset, and the contact point between the locking member 621 and the safety push button 61 is located at the rightmost side of the long slot 617.
[0103] Furthermore, when the sliding assembly 50 is pressed to move to the right, the knife holder 40 is able to rotate from the horizontal position to the longitudinal position via the transition position, and the knife holder 40 abuts against the front end of the base 611 of the safety push button 61. The rotation of the knife holder 40 enables the safety push button 61 to overcome the resistance of the safety spring 64 and move to the right, thereby preventing the stop portion 615 from interfering with the blade 45 and hindering the knife holder 40 from changing direction. At this time, the contact point between the locking member 621 and the safety push button 61 moves to the left along the long slot 617. When the knife holder 40 is close to the longitudinal position, the knife holder 40 is separated from the safety push button 61, and the force of the safety spring 64 causes the safety push button 61 to move forward and reset. The contact point between the locking member 621 and the safety push button 61 is located at the rightmost side of the long slot 617, and the stop portion 615 is located below the blade 45, thereby stopping the blade 45 from rotating.
[0104] In some embodiments, as shown in FIG25 , the deformable folding knife further includes a self-locking assembly 70, which includes a self-locking push button 71 and a self-locking spring 72. The self-locking push button 71 is longitudinally movably disposed on the inner housing 20 and is adapted to abut against the driving member 30. The self-locking spring 72 provides a force for the self-locking push button 71 to move toward the driving member 30. As shown in FIG21 , the self-locking push button 71 is provided with a protruding first self-locking portion 711. The upper housing 21 is provided with a self-locking hole 213. The first self-locking portion 711 extends through the self-locking hole 213 toward the outer housing 11. The inner surface of the outer housing 11 is provided with a protruding second self-locking portion 15. The driving member 30 acts on the self-locking push button 71, causing the first self-locking portion 711 to detachably abut against the second self-locking portion 15.
[0105] Specifically, in combination with Figures 21 and 33 to 36, when the deformable folding knife is in the unfolded state, the second self-locking portion 15 on the outer shell 11 is located next to the self-locking hole 213 of the upper shell 21; as shown in Figure 33, further when the blade 45 is in the longitudinal position, the drive member 30 abuts against the self-locking push button 71, and the self-locking spring 72 is compressed, causing the self-locking push button 71 to move longitudinally backward along the axial direction, further separating the first self-locking portion 711 from the second self-locking portion 15, and the inner shell 20 is able to rotate relative to the outer shell 11 and fold into the main accommodating cavity 12.
[0106] As shown in Figures 35 and 36, when the blade 45 leaves the longitudinal position, the drive member 30 separates from the self-locking push button 71, and the self-locking spring 72 pushes the self-locking push button 71 to move longitudinally forward along the axial direction, further causing the first self-locking portion 711 to abut against the second self-locking portion 15, thereby preventing the inner shell 20 from rotating relative to the outer shell 11, so that the deformable folding knife remains in the unfolded state, thereby preventing the blade 45 from being unable to be smoothly accommodated in the main accommodating cavity 12 and causing accidental injury.
[0107] It is understood that when the blade 45 is in the longitudinal position, the inner housing 20 rotates relative to the outer housing 11, allowing the blade 45 to be smoothly accommodated in the main accommodating cavity 12. However, when the blade 45 is in the transitional position or the transverse position, even if the inner housing 20 is able to rotate relative to the outer housing 11, the blade 45 will interfere with the outer housing 11, which may cause damage to the outer housing 11 or accidental injury to the user. The self-locking assembly 70 allows the inner housing 20 to be rotated and folded toward the outer housing 11 when the blade holder 40 is in the longitudinal position, while the blade holder 40 remains unfolded when it is in other positions, thereby preventing the blade 45 from being smoothly accommodated in the main accommodating cavity 12 and causing accidental injury.
[0108] In some embodiments, as shown in Figures 20, 27 and 28, the deformable folding knife also includes a locking assembly 80, which includes a locking member 81 and a locking spring 82. The locking member 81 can be elastically pressed to the outer shell 11 through the locking spring 82. The locking member 81 is provided with a radially protruding locking portion 811, and the inner shell 20 is provided with a plurality of locking notches 223. The locking portion 811 can be detachably engaged with the locking notches 223, so that the inner shell 20 can be maintained in an expanded state or a folded state.
[0109] Specifically, by pressing the locking member 81, the locking spring 82 is compressed, so that the locking portion 811 is separated from the locking notch 223, and the inner shell 20 can be rotated relative to the outer shell 11 to rotate out of or into the main accommodating cavity 12; when the locking member 81 is released, when the locking portion 811 engages with the locking notch 223, the inner shell 20 can be maintained in the expanded state or the folded state.
[0110] In a specific embodiment, a locking notch 223 is provided on each side of the lower shell 22. When the locking portion 811 is connected to the locking notch 223 on one side, the inner shell 20 remains in an unfolded state, thereby preventing the inner shell 20 from rotating relative to the outer shell 11 during use and causing safety hazards, thereby facilitating cutting or scraping operations; when the locking portion 811 is connected to the locking notch 223 on the other side, the inner shell 20 remains in a folded state, thereby preventing the inner shell 20 from rotating out of the main accommodating cavity 12 during storage or carrying, thereby exposing the blade and causing safety hazards.
[0111] In some embodiments, as shown in Figures 31 and 32, the tool holder 40 includes a first tool holder 41, an intermediate tool holder 43, a second tool holder 42 and a tool holder spring piece 44. The first tool holder 41 is provided with a spring piece groove 412 and a first mounting groove 413 on the side facing the second tool holder 42. The intermediate tool holder 43 is accommodated in the first mounting groove 413 and is rotatably connected to the first tool holder 41 and the second tool holder 42. The tool holder spring piece 44 is accommodated in the spring piece groove 412, so as to provide a force to the intermediate tool holder 43 against the second tool holder 42, so that the blade 45 can be detachably installed between the second tool holder 42 and the intermediate tool holder 43. The first guide member 411 protrudes radially outward from the first tool holder 41, is pivotally connected to the first connecting hole 33 at the front end of the driving member 30, and is connected to the first guide rail 212 on the inner side of the upper shell 21. It is driven by the driving member 30 and can move along the first guide rail 212. The second guide member 421 protrudes radially outward from the second tool holder 42 eccentrically relative to the first guide member 411, and is connected to the second guide rail 221 of the lower shell 22.
[0112] Specifically, the intermediate blade holder 43 includes a main body 431, a rotating shaft 433, and an extension 432. The rotating shaft 433 is located on both sides of the upper end of the main body 431 and is rotatably connected to the first blade holder 41. The extension 432 extends upward from the upper end of the main body 431, is exposed to the outside world from the upper end of the blade holder 40, and is movably positioned between the first blade holder 41 and the second blade holder 42. Furthermore, a limiting portion 435 and a fixing portion 434 are protruding from the lower end of the main body 431 toward one side of the second blade holder 42. The blade 45 is provided with a limiting opening 452 and a mounting hole 451 extending therethrough. The limiting portion 435 on the main body 431 is adapted to cooperate with the limiting opening 452, and the fixing portion 434 is adapted to pass through the mounting hole 451 to secure the blade 45. A second mounting groove 422 and a third mounting groove 423 are provided on one side of the second tool holder 42 facing the middle tool holder 43 . The second mounting groove 422 is used to accommodate the end of the fixing portion 434 , and the third mounting groove 423 is used to avoid the end of the limiting portion 435 .
[0113] It is understood that the extension portion 432 and the main body 431 are located on either side of the rotation axis of the rotating shaft portion 433. By moving the extension portion 432, the elastic force of the blade holder spring 44 is overcome, causing the main body 431 to rotate away from the second blade holder 42, further separating the fixing portion 434 at the lower end of the main body 431 from the mounting hole 451, thereby allowing the blade 45 to be replaced. In one embodiment, the thickness of the main body 431 gradually decreases from top to bottom, making the structure of the blade holder 40 more compact and facilitating a reduction in the size of the blade holder 40.
[0114] In some embodiments, as shown in FIG. 20 and FIG. 25 , the deformable folding knife further includes a side clip 90 , which is elastically disposed on the outer side of the housing 11 for clamping objects such as notebooks, pockets, etc., to help prevent the knife from being lost.
[0115] The above describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and description merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
