[0044] A deformable tool, such as Figures 1 to 11 As shown, it 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 with the outside. 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 is drivably connected to the knife seat 30. The front side of the knife seat 30 is pivoted to the front side of the knife seat 30, so that the knife seat 30 can move along the first guide rail 222, that is, the driving member 23 is pivoted to the front side of the knife seat 30, and the driving member 23 moves along the first guide rail 222, and further under the driving action of the driving member 23, the knife seat 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, and the back side of the knife seat 30 is pivoted to the second guide rail 121, so that the knife seat 30 can move along the second guide rail 121. It can be understood that the knife seat 30 is connected to the driving member 23 and the second guide rail 121 at the same time, so that it can move along the first guide rail 222 and the second guide rail 121, and the knife seat 30 can translate and / or rotate through the joint guidance of the first guide rail 222 and the second guide rail 121. When the driving member 23 moves longitudinally along the axial direction relative to the fixed surface 122, the knife holder 30 can be selectively rotated into or out of the accommodating cavity 13, so that the knife holder 30 can be alternately changed in multiple positioning angles between the longitudinal position and the transverse position. In other words, through the driving action of the driving member 23 on the knife holder 30, the knife holder 30 can be translated and / or rotated under the guidance of the first guide rail 222 and the second guide rail 121, and further can quickly realize the multi-angle positioning of the tool, so that the tool can be converted between the utility knife and the scraper, which is easy to operate, conducive to improving work efficiency, and has a compact structure.

[0045] In some embodiments, Fig.11 and Fig.12As shown, 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 arranged on the front and back sides of the tool holder 30 in a staggered manner. 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, by connecting the first guide member 311 to the driving member 23, the first guide member 311 further cooperates with the first guide rail 222 for movement, and the second guide member 321 cooperates with the second guide rail 121 for movement to generate deflection and guidance, further generating a thrust to push the knife seat 30 in the direction of rotation, so that the knife seat 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.

[0046] Specifically, if Figures 1 to 10 As shown, 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. Further, 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 realize multi-angle positioning of the knife, realize multiple uses of one knife, and facilitate storage and carrying.

[0047] In some embodiments, Fig.11 and Fig.12 As shown, 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, and 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 Figure 2 As shown, the first guide member 311 on the knife seat 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, the first guide member 311 is driven to move along the first guide rail 222, and the second guide member 321 moves along the second guide rail 121, further enabling the knife seat 30 to translate and / or rotate smoothly to achieve multi-angle positioning of the knife. When the sliding member 50 is assembled on the driving surface 234, in an optional embodiment, as shown in FIG. Fig.18As shown, the first guide member 311 on the knife seat 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, the driving surface 234 is pushed to translate and / or rotate, and the first guide member 311 is further driven to move along the first guide rail 222, and the second guide member 321 moves along the second guide rail 121, so that the knife seat 30 translates and / or rotates smoothly to achieve multi-angle positioning of the tool. It can be understood that the first guide member 311 can be connected to the driving member 23, and the driving member 23 moves along the first guide rail 222, so that the first guide member 311 moves along the first guide rail 222 indirectly, and 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 driving member 23.

[0048] In some embodiments, Figures 1 to 10 As shown, the first guide rail 222 and the second guide rail 121 are linear structures and / or arc 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 the port 14 or rotates back to the accommodating cavity 13. 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 at other angles to the axis to realize multi-angle positioning of the tool and achieve multiple uses of one knife.

[0049] Specifically, if Figures 1 to 10As shown, the second guide rail 121 is provided with a straight section 1211, the main branch section 1212 and the straight section 1211 are connected in one piece, the main branch section 1212 extends outward in an arc shape or bends in a direction deviating from the straight section 1211, and the extension direction of the straight section 1211 is the same as the extension direction of the first guide rail 222. When the knife seat 30 moves linearly along the straight section 1211 of the second guide rail 121 and the first guide rail 222, the blade 35 on the knife seat 30 is in a retracted state retracted into the accommodating cavity 13 or an extended state extending out of the port 14. When the knife seat 30 moves in a turning direction along the main branch section 1212 of the second guide rail 121 and the first guide rail 222, the blade 35 on the knife seat 30 is able to change direction at multiple positioning angles between the longitudinal position and the transverse position. In the longitudinal position, the blade edge of the blade 35 is parallel to the axial direction; in the transverse position, the blade edge of the blade 35 is perpendicular to the axial direction.

[0050] That is to say, when the first guide member 311 on the tool holder 30 moves along the first guide rail 222 and the second guide member 321 is located at the straight section 1211 of the second guide rail 121, the blade is parallel to the axial direction, and the tool holder 30 translates 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 tool holder 30 moves along the first guide rail 222 and the second guide member 321 is located at the main branch section 1212 of the second guide rail 121, the tool holder 30 is able to move and change direction and rotate, so that the angle between the blade and the axis changes, so as to achieve multi-angle positioning and meet various usage requirements.

[0051] In another alternative embodiment, Fig.18 As shown, 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 seat 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 seat 30 can be changed in direction at multiple positioning angles between the longitudinal position and the transverse position.

[0052] In some embodiments, Fig.11 As shown, 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 with the second guide member 321 on the knife seat 30.

[0053] In some embodiments, Fig.11 and Fig.12As shown, the deformable tool further includes a moving assembly 20, which includes a push button assembly 21 and a positioning member 22. The positioning member 22 is arranged between the push button assembly 21 and the driving member 23, and 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 is connected to the driving member 23. 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. 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 transition position between the longitudinal position and the transverse position.

[0054] That is, the positioning member 22 is fixedly arranged with the upper shell 11, and the back of the positioning member 22 is provided with a first guide rail 222, which can be matched with the joint parts 232 protruding from both sides of the driving member 23, so that the driving member 23 moves along the first guide rail 222, and further the first guide member 311 on the knife seat 30 is pivotally connected with the first connecting hole 233 at the front end of the driving member 23, so that the first guide member 311 moves along the first guide rail 222, and the inner surface of the lower shell 12 is provided with a second guide rail 121, which can be connected with the second guide member 321 on the knife 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 with the rear end of the driving member 23, and the driving member 23 can be pushed to move by the push button member, and further the knife seat 30 can be translated and / or rotated. Furthermore, the push button assembly 21 can be elastically locked in the positioning groove 221, so that the knife seat 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 joint 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 shell 10, the movement path of the knife seat 30 can be limited, so that the blade 35 can smoothly transition to multiple positioning positions without 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.

[0055] In some embodiments, Fig.11 and Fig.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 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. 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 is convenient for pushing the push button bracket 211 to make the driving member 23 move along the first guide rail 222.

[0056] Further, the push button bracket 211 includes a first connecting section 2111 and a second connecting section 2112 distributed perpendicularly to the driving surface 234, the positioning groove 221 includes an elongated moving area 2211 extending along the axial direction and a plurality of positioning areas 2212 distributed at intervals, the first connecting section 2111 passes through the push button groove 111 of the upper shell 11, and is suitable for moving along the moving area 2211 of the positioning groove 221, the second connecting section 2112 is connected to the second connecting hole 231 on the driving member 23, and the second connecting section 2112 is suitable for cooperating with the positioning area 2212 to lock the driving member 23, so that the knife seat 30 is kept in an optional position. In other words, the first connecting section 2111 of the push button bracket 211 is suitable for moving along the push button groove 111 of the upper shell 11, and the first connecting section 2111 is also suitable for moving 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, by pressing and pushing the push button assembly 21, the push button spring 212 is compressed, the push button bracket 211 moves inward, the second connection 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, the first connection section 2111 and the moving area 2211 cooperate, and the push button assembly 21 is able to drive the driving member 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 connection section 2112 of the push button bracket 211 cooperates with the positioning area 2212, and the driving member 23 is locked, and the position of the knife holder 30 is further positioned. The position of the knife holder 30 can be converted and locked by single-handed operation, which improves the convenience and safety of operation, and the knife holder 30 can move and turn smoothly through the first guide rail 222 and the second guide rail 121, making it easier and smoother to press and push the push button assembly 21.

[0058] Further, such as Figures 13 to 15As shown, the deformable tool also includes an anti-rotation component 70, which is rotatably connected to the driving component 23 and can be moved longitudinally in the axial direction together with the driving 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 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 component 70 to rotate relative to the driving component 23. The other end of the anti-rotation component 70 is protrudingly provided with a stop portion 71 toward one side of the knife seat 30, and the front side of the knife seat 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 be engaged or separated from the stop groove 314. It is understandable that, when the push button assembly 21 is pressed, the push button assembly 21 moves toward the inside of the knife housing 10, driving the anti-rotation member 70 to rotate, so that the stop portion 71 is separated from the stop groove 314, and the knife seat 30 is able to rotate relative to the driving member 23; when the push button assembly 21 is released, the push button assembly 21 moves toward the outside of the knife housing 10, driving the anti-rotation member 70 to rotate, so that the stop portion 71 is engaged with the stop groove 314, and the knife seat 30 is locked with the driving member 23, so that the knife seat 30 is maintained in the longitudinal position, the transverse position, or other optional positions between the longitudinal position and the transverse position. In other words, under the dual action of the cooperation between the push button assembly 21 and the positioning groove 221, and the cooperation between the anti-rotation member 70 and the knife seat 30, the position of the knife seat 30 can be locked, thereby improving the reliability and safety of the deformable knife when in use. In another optional embodiment, an anti-rotation spring is provided below the side of the anti-rotation member 70 close to the push button assembly 21 , and 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 to engage with the stop groove 314 .
