Based on the specific embodiments in the present application, all other specific embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0021] Example 1

[0022] Please refer to Figures 1-3The utility model provides a kind of combined multifunctional batch cutting knife, including fixed shaft rod 1 and several open blade 5, fixed shaft rod 1 penetrates several open blade 5, several size fixed interval pipe 3 are sleeved outside fixed shaft rod 1, size fixed interval pipe 3 is located between two adjacent open blade 5, several size fixed interval pipe 3 are all installed with telescopic spring 4.

[0023] In the embodiment, the front and rear ends of the fixed shaft rod 1 are provided with threads, and the combination of the fixed shaft rod 1, the size fixed interval pipe 3 and the open blade 5 is operated as follows: first, a single size fixed interval pipe 3 is sleeved outside the fixed shaft rod 1, then a single open blade 5 is sleeved outside the size fixed interval pipe 3, so that the telescopic spring 4 and the open blade 5 are in contact with each other, then the subsequent size fixed interval pipe 3 and open blade 5 to be assembled are sleeved in turn along the arrangement direction of the fixed shaft rod 1, until all are assembled, the D-shaped pull wire fixing ring 6 and the triangular support frame 7 are erected above the open blade 5, the pull wire telescopic head 14 is inserted into the inside of the D-shaped pull wire fixing ring 6, the pull wire telescopic head 14 is sleeved on the front and rear ends of the fixed shaft rod 1, and a slidable gap between the pull wire telescopic head 14 and the fixed shaft rod 1 is reserved at the threaded position of the positioning nut 2, then the open blade 5 and the size fixed interval pipe 3 sleeved are kept in a fixed state by screwing the positioning nut 2 on the front and rear ends of the fixed shaft rod 1, and the overall cutter is adjusted by replacing size fixed interval pipes 3 of different lengths according to the batch cutting interval demand through combined assembly, thereby improving the adaptability to various batch cutting demands.

[0024] The top of the open blade 5 is provided with two D-shaped pull wire fixing rings 6, the two ends of the D-shaped pull wire fixing ring 6 are slidably connected with the pull wire telescopic head 14, the front and rear ends of the fixed shaft rod 1 are slidably connected inside the two pull wire telescopic heads 14, the top of the D-shaped pull wire fixing ring 6 is fixedly connected with the triangular support frame 7, the inside of the triangular support frame 7 is fixedly connected with the pull wire fixing frame 8 and the combined handle fixing frame 9, the top of the open blade 5 is provided with the combined handle 16, the two ends of the combined handle 16 are fixedly connected with the contraction pull wire 18 through the pull wire fixing wire 10, the bottom end of the contraction pull wire 18 is slidably penetrated through the combined handle fixing frame 9 and the pull wire fixing frame 8 in turn, and the bottom end of the contraction pull wire 18 is fixedly connected with the pull wire telescopic head 14, and the top of the triangular support frame 7 is fixedly connected with the main body operation handle 13.

[0025] In this embodiment, when the cutting operation is performed, the operator holds the main body operating handle 13 with the palm, and holds the combined pull handle 16 with the fingers, and then the combined pull handle 16 is pulled together towards the main body operating handle 13, and the combined pull handle 16 is used as a hand support point during cutting. When the combined pull handle 16 is gripped, the contraction pull wire 18 pulls the pull wire telescopic head 14, and the pull wire telescopic head 14 slides along the inside limiting path of the D-shaped pull wire fixing ring 6, so as to avoid the left and right swinging of the blade during the cutting operation. At the same time, during the sliding of the pull wire telescopic head 14 along the D-shaped pull wire fixing ring 6, the extension spring 4 is in a compressed state due to the pushing force of the pull wire telescopic head 14, so as to fix the cutting interval of the blade. At this time, the equal-interval batch cutting of the object can be completed by pressing the blade down. After the equal-interval batch cutting of the object is completed, the operator releases the grip force on the combined pull handle 16, the extension spring 4 is no longer in contact with the blade, and the blade is pushed back to the original position by the extension spring 4. At the same time, the pull wire telescopic head 14 slides along the original path of the D-shaped pull wire fixing ring 6, and the object is separated under the pushing force of the blade. The cutting and separation operation is completed by a single action. Compared with the conventional batch cutting knife, the multifunctional requirement can be met, and the operation convenience is improved.

[0026] The inside of the triangular support frame 7 is provided with a pull wire outer sleeve 15, the pull wire outer sleeve 15 is sleeved outside the contraction pull wire 18, and the top of the pull wire outer sleeve 15 is in contact with the bottom of the pull wire fixing frame 8. The pull wire outer sleeve 15 is used for limiting the sliding of the contraction pull wire 18, so as to ensure the stability of the traction path of the contraction pull wire 18 when the contraction pull wire 18 pulls the pull wire telescopic head 14 to slide along the inside of the D-shaped pull wire fixing ring 6.

[0027] The two ends of the combined pull handle 16 are threadedly connected with pull wire fixing screw caps 11, and the pull wire fixing screw caps 11 are used for positioning and locking after the pull wire fixing wire 10 is sleeved and installed. The two ends of the combined pull handle 16 are provided with threads, the top end of the contraction pull wire 18 is fixedly connected with the pull wire fixing wire 10, the pull wire fixing wire 10 is positioned by sleeving and assembling between the combined pull handle 16 and the pull wire fixing wire 10, and then the pull wire fixing screw cap 11 is screwed on the threaded end of the combined pull handle 16. When the combined pull handle 16 is slid upward under the grip force, the contraction pull wire 18 can stably pull the pull wire telescopic head 14.

[0028] The two ends of the main body operating handle 13 are clamped and connected with handle sealing covers 12. The handle sealing covers 12 block the double-end interface surfaces of the main body operating handle 13, so as to avoid cutting the hands of the operator.

[0029] The D-shaped pull wire fixing ring 6 has a silicone pad 17 fixedly connected to its bottom. When the operator grips the combined handle 16, the retracting pull wire 18 pulls the pull wire telescopic head 14 to slide, causing the blade 5 to slide towards the bottom edge of the D-shaped pull wire fixing ring 6. The silicone pad 17 provides a contact buffer. Simultaneously, if the cutting platform is not flat enough, the silicone pad 17 can supplement the downward pressure distance of the blade 5 located on the concave surface. This allows the blade 5, after being pressed down on the concave surface, to continue moving towards the concave surface due to the contact between its top and the silicone pad 17. This ensures the cutting surface reaches the bottom of the concave surface stably, guaranteeing the cutting depth and preventing insufficient cutting depth caused by concavity in the cutting platform, thereby improving the cutting completion rate.

[0030] The working principle of this invention is as follows: When operating the cutting mechanism, the palm is placed on the main operating handle 13, and the fingers grasp the combined handle 16. Then, by bringing the combined handle 16 together towards the main operating handle 13, the main operating handle 13 and the combined handle 16 serve as the hand fulcrum during cutting. When the combined handle 16 is brought together towards the main operating handle 13, the retractable pull cable 18 pulls the pull cable telescopic head 14 to slide inward to the D-shaped pull cable fixing ring 6, causing the telescopic spring 4 to be compressed and contracted by the thrust generated when the pull cable telescopic head 14 slides, thereby maintaining the fixed cutting spacing of the blade 5. Then, the blade 5 is pressed down to cut the object in batches at equal intervals. After the cutting is completed, the grip on the combined handle 16 is released, allowing the telescopic spring 4 to return to its original position and push the blade 5 back into place, separating the cut items.

[0031] Example 2

[0032] like Figure 1 As shown, a combined multi-functional batch cutting knife includes a fixed shaft 1 and several sharpened blades 5. The fixed shaft 1 passes through the several sharpened blades 5. Several fixed-size spacing tubes 3 are sleeved on the outside of the fixed shaft 1. The fixed-size spacing tubes 3 are located between two adjacent sharpened blades 5. Each of the several fixed-size spacing tubes 3 is equipped with a telescopic spring 4. Both ends of the fixed shaft 1 are threaded with positioning nuts 2. Positioning nuts 2 are used to limit the detachment of the fixed spacing tube 3 after installation. Two sets of D-shaped pull wire fixing rings 6 are provided above the blade 5. Both ends of the D-shaped pull wire fixing rings 6 are slidably connected with pull wire telescopic heads 14. The front and rear ends of the fixed shaft 1 are respectively slidably connected to the inner side of the two pull wire telescopic heads 14. A triangular support frame 7 is fixedly connected to the top of the D-shaped pull wire fixing rings 6. A pull wire fixing frame 8 and a combined handle fixing frame 9 are fixedly connected to the inner side of the triangular support frame 7. A combined handle 16 is provided on the top of the blade 5. Both ends of the combined handle 16 are fixedly connected with retractable pull wires 18 through pull wire fixing threads 10. The bottom end of the retractable pull wire 18 slides through the combined handle fixing frame 9 and the pull wire fixing frame 8 in sequence. The bottom end of the retractable pull wire 18 is fixedly connected to the pull wire telescopic head 14. The main body operating handle 13 is fixedly connected to the top of the triangular support frame 7.

[0033] Wherein, the upper of the blade 5 is equipped with two groups of D type stay fixing ring 6, the two ends of the D type stay fixing ring 6 are slidably connected with the stay telescopic head 14, the front and back ends of the fixed shaft rod 1 are slidably connected to the inner side of the two stay telescopic heads 14, the top of the D type stay fixing ring 6 is fixedly connected with the triangular support frame 7, the inner side of the triangular support frame 7 is fixedly connected with the stay fixing frame 8 and the combined handle fixing frame 9, the top of the blade 5 is equipped with the combined handle 16, the two ends of the combined handle 16 are fixedly connected with the contraction stay 18 through the stay fixing wire 10, the bottom end of the contraction stay 18 is sequentially slidably penetrated through the combined handle fixing frame 9 and the stay fixing frame 8, and the bottom end of the contraction stay 18 is fixedly connected with the stay telescopic head 14, and the top of the triangular support frame 7 is fixedly connected with the main body operation handle 13.

[0034] In this embodiment, the different from the embodiment 1 is that the use steps of the blade 5 after the cutting interval adjustment according to the required batch cutting length are as follows:

[0035] Step one, first select the size fixed interval pipe 3 corresponding to the required cutting interval, and then slide and install the blade 5 and the size fixed interval pipe 3 along the path of the fixed shaft rod 1, after that, the stay telescopic head 14 is sleeved on the front and back ends of the fixed shaft rod 1, and is screwed on the front and back ends of the fixed shaft rod 1 through the positioning nut 2 to lock the fixed shaft rod 1 and the stay telescopic head 14;

[0036] Step two, the stay fixing wire 10 is sleeved on the two ends of the combined handle 16, and is screwed on the combined handle 16 through the stay fixing screw cap 11, so that the stay fixing screw cap 11 limits the stay fixing wire 10, and the contraction stay 18 is fixedly assembled with the combined handle 16;

[0037] Step three, hold the main body operation handle 13 with the palm, hold the combined handle 16 with the fingers, and make the combined handle 16 converge to the main body operation handle 13 as the hand support point during cutting, at this time, the contraction stay 18 is pulled by the gripping action of the combined handle 16 to slide to the inner side of the D type stay fixing ring 6. The stay fixing frame 8 and the combined handle fixing frame 9 are used to limit the movement path of the contraction stay 18, keep the sliding path of the contraction stay 18 vertical, and then ensure the stability of the traction of the D type stay fixing ring 6 and the stay telescopic head 14, so that the extension spring 4 is compressed and contracted due to the thrust generated when the stay telescopic head 14 slides, the fixed cutting interval of the blade 5 is kept, and the batch cutting of objects with equal interval is completed by pressing the blade 5.

[0038] Step 4: Remove the sharpening blade 5 and readjust the cutting spacing. Remove it from the threaded end of the fixed shaft 1 by turning the positioning nut 2, thereby releasing the restriction on the wire extension head 14. After pulling the wire extension head 14 away from the outside of the D-shaped wire fixing ring 6, the restriction of the wire extension head 14 on the size fixed spacing tube 3 is released. At this time, by sequentially pulling the size fixed spacing tube 3 and the sharpening blade 5 away from the outside of the fixed shaft 1, the fixed shaft 1, the size fixed spacing tube 3 and the sharpening blade 5 are in a separate state, which can be assembled and used when changing the cutting spacing later, improving the adaptability to different cutting spacing requirements of the cutting object.

[0039] Example 3

[0040] like Figure 1 As shown, a combined multi-functional batch cutting knife includes a fixed shaft 1 and several sharpened blades 5. The fixed shaft 1 passes through the several sharpened blades 5, and several fixed-size spacing tubes 3 are sleeved on the outside of the fixed shaft 1. The fixed-size spacing tubes 3 are located between two adjacent sharpened blades 5, and each of the fixed-size spacing tubes 3 is equipped with a telescopic spring 4. Both the front and rear ends of the fixed shaft 1 are threaded with positioning nuts 2, which are used to limit the detachment of the fixed-size spacing tubes 3 after installation. Two sets of D-shaped pull cable fixing rings 6 are provided above the blade 5. Both ends of the D-shaped pull cable fixing rings 6 are slidably connected to pull cable telescopic heads 14. The front and rear ends of the fixed shaft rod 1 are slidably connected to the inner sides of the two pull cable telescopic heads 14 respectively. A triangular support frame 7 is fixedly connected to the top of the D-shaped pull cable fixing rings 6. A pull cable fixing frame 8 and a combined handle fixing frame 9 are fixedly connected to the inner side of the triangular support frame 7. A combined handle 16 is provided at the top of the blade 5. Both ends of the combined handle 16 are fixedly connected to a retractable pull cable 18 through a pull cable fixing wire 10. The bottom end of the retractable pull cable 18 slides through the combined handle fixing frame 9 and the pull cable fixing frame 8 in sequence, and the bottom end of the retractable pull cable 18 is fixedly connected to the pull cable telescopic head 14. The main body operating handle 13 is fixedly connected to the top of the triangular support frame 7.

[0041] In the embodiment, the article only needs to be batch cut without cutting and synchronously breaking, and the cutter can be assembled by the following assembly method. First, select the size fixed interval pipe 3 corresponding to the required cutting interval, and take off the retractable spring 4 from the outside of the size fixed interval pipe 3, then slide and install the blade 5 and the size fixed interval pipe 3 along the fixed shaft rod 1 in turn. After sliding and installing the size fixed interval pipe 3, the pull line retracting head 14 is sleeved on the front and rear ends of the fixed shaft rod 1, and is screwed on the front and rear ends of the fixed shaft rod 1 through the positioning nut 2 to lock the fixed shaft rod 1 and the pull line retracting head 14. Different from the embodiment, when the positioning nut 2 is screwed, the screwing position of the positioning nut 2 does not need to reserve the slidable gap between the pull line retracting head 14 and the fixed shaft rod 1, and the positioning nut 2 is continuously screwed until the positioning nut 2 locks the pull line retracting head 14 and the fixed shaft rod 1. Then, only the palm part grips the main body operation handle 13, and the main body operation handle 13 is used as the hand support point during cutting, then the blade 5 is pressed down to cut the objects at equal intervals, and then it is suitable for direct cutting of conventional objects without breaking.
