[0024] like Figure 1 , Figure 2 and Figure 6 As shown, the embodiment provides a wire cutter 1000, which can be used to cut conduits. The conduits can be structures such as hydraulic brake lines for bicycles, electric bicycles, motorcycles, and other vehicles.

[0025] In some embodiments, the wire cutter 1000 may include a first handle 100, a blade 300, and a second handle 200. One end of the blade 300 may be fixedly connected to the first handle 100, and the other end of the blade 300 may protrude relative to the first handle 100. In an embodiment, one end of the second handle 200 may have a wire-cutting hole 211. The blade 300 may pass through the wire-cutting hole 211 and be pivotally connected to the second handle 200. That is, relative rotation may occur between the blade 300 and the second handle 200. Accordingly, the wire cutter 1000 may include a closed state 1002 and an open state 1001.

[0026] When the wire cutter 1000 is in the closed state 1002, the blade 300 can be accommodated in the wire cutting hole 211. When the wire cutter 1000 is in the open state 1001, the end of the blade 300 away from the first handle 100 can protrude relative to the side of the second handle 200 opposite to the first handle 100. It can be understood that the wire cutter 1000 can perform a cutting action during the process of switching from the open state 1001 to the closed state 1002.

[0027] In some embodiments, the second handle 200 is further provided with a threading hole 212, which may be located at one end of the second handle 200 near the wire-cutting hole 211. The threading hole 212 can penetrate the second handle 200 in a direction perpendicular to the blade 300, and correspondingly, the threading hole 212 can penetrate the wire-cutting hole 211 and communicate with it. It is understood that the threading hole 212 can be divided into two segments by the wire-cutting hole 211.

[0028] In this embodiment, when the wire cutter 1000 cuts the pipeline, the pipeline can be threaded through the threading hole 212, and simultaneously, the pipeline can pass through the cutting hole 211 and be located on the moving path of the blade 300. It is understood that a portion of the pipeline located in the threading hole 212 can extend in a straight line. Subsequently, the user can press the first handle 100 and the second handle 200 to rotate the blade 300 relative to the second handle 200. The wire cutter 1000 can switch from an open state 1001 to a closed state 1002. The protruding end of the blade 300 relative to the second handle 200, away from the first handle 100, can move into the cutting hole 211, meaning the blade 300 can be accommodated in the cutting hole 211 and can cut the pipeline threaded through the threading hole 212, thus achieving the wire cutting action. Since the section of the pipeline in the threading hole 212 extends in a straight line, the section of the pipeline in the cutting hole 211 is perpendicular to the blade 300. When the blade 300 cuts the pipeline, the cutting end face is flatter and burr-free, which significantly improves the cutting effect compared to the traditional wire cutter 1000.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 9 As shown, in some embodiments, the first handle 100 may have a columnar structure. The first handle 100 may include a first end 101 and a second end 102 distributed along its own extending direction. A connecting groove 110 may be formed at the end of the first handle 100 near the first end 101. The connecting groove 110 may have a first opening 111 and a second opening 112 disposed opposite to each other, wherein the length of the first opening 111 along the axial direction of the first handle 100 may be less than the length of the second opening 112 along the axial direction of the first handle 100.

[0030] In some embodiments, the first handle 100 may be generally cylindrical, and correspondingly, the side of the first handle 100 opposite to the second handle 200 may be an arc surface. This improves the user's comfort when holding the first handle 100 and makes it easier for the user to apply force to the first handle 100 for cutting operations.

[0031] In other embodiments, the side of the first handle 100 facing away from the second handle 200 may be an arc surface, while the side of the first handle 100 facing the second handle 200 may be a flat surface. Accordingly, the first handle 100 may be generally semi-cylindrical in shape.

[0032] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, in some embodiments, the blade 300 may include a connecting portion 310 and a shearing portion 320 connected together. The connecting portion 310 can be inserted into the connecting groove 110 and can be detachably connected to the first handle 100 via a locking bolt 410. This facilitates the disassembly and replacement of the blade 300 and adjusts its posture, improving user convenience. In some embodiments, the connecting portion 310 and the shearing portion 320 may be an integral structure.

[0033] In some embodiments, the cutting portion 320 may protrude from the side of the connecting groove 110 away from the second end 102, and the cutting portion 320 may pass through the wire cutting hole 211 and be pivotally connected to the second handle 200 via a pin 420. Additionally, a blade 321 may be disposed on one side of the cutting portion 320. When the wire cutter 1000 is in the open state 1001, the end of the cutting portion 320 away from the connecting portion 310 may protrude from the side of the second handle 200 away from the first handle 100, and the blade 321 may face the side of the wire cutting hole 211.

[0034] In some embodiments, the shearing portion 320 has a protrusion 323 protruding from the side facing the blade 321. The protrusion 322 may be located at one end of the shearing portion 320 near the connecting portion 310.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the second handle 200 may include a connected operating portion 210 and a hand-held portion 220. A wire-cutting hole 211 may be formed in the operating portion 210. The cutting portion 320 of the blade 300 may pass through the wire-cutting hole 211 and may be pivotally connected to the operating portion 210 via a pin 420. The hand-held portion 220 may be connected to the end of the operating portion 210 facing the first handle 100, and the hand-held portion 220 may be disposed opposite to the first handle 100.

[0036] In some embodiments, the operating part 210 may have a plurality of wire-passing holes 212. At least one wire-passing hole 212 has an inner diameter different from the other wire-passing holes 212. Therefore, the wire cutter 1000 can be applied to cutting pipes of different outer diameters, improving the versatility and utilization of the wire cutter 1000.

[0037] In some embodiments, the operating part 210 may have a first set of wire holes 2121 and a second set of wire holes 2122, each including multiple wire holes 212. The multiple wire holes 212 of the first set of wire holes 2121 may be distributed along an arc, and the center of the arc may be located on the side of the operating part 210 away from the first handle 100. Similarly, the multiple wire holes 212 of the second set of wire holes 2122 may also be distributed along an arc, and the center of the arc may be located on the side of the operating part 210 away from the first handle 100. In this embodiment, the first set of wire holes 2121 may be located on the side of the second set of wire holes 2122 facing the first handle.

[0038] In some embodiments, the inner diameters of the plurality of wire holes 212 in the first group of wire holes 2121 are all different.

[0039] In some embodiments, the inner diameters of the plurality of wire holes 212 in the second group of wire holes 2122 are all different.

[0040] In some embodiments, the inner diameter of any one of the wire holes 212 in the first group of wire holes 2121 is different from the inner diameter of any one of the wire holes 2122 in the second group of wire holes 2122.

[0041] In other embodiments, the operation part 210 has a plurality of threading holes 212, wherein the inner diameter of some of the threading holes 212 may be set to be the same.

[0042] In some embodiments, both the first group of wire holes 2121 and the second group of wire holes 2122 may include four wire holes 212.

[0043] In other embodiments, the first group of threading holes 2121 and the second group of threading holes 2122 may each include one, two, three or five threading holes.

[0044] In some other embodiments, the operation unit 210 may include a first set of wire holes 2121 or a second set of wire holes 2122.

[0045] like Figures 1 to 6 As shown, in some embodiments, the blade 300 and the first handle 100 can have two connection modes. When the blade 300 and the first handle 100 are in the first connection mode, the first handle 100 is connected to the blade 300, and the first opening 111 of the connecting groove 110 faces the second handle 200. The blade edge 321 of the blade 300 can pass through the second set of wire holes 2121 to cut the pipeline passing through the second set of wire holes 2122. In this state, the connecting part 310 of the blade 300 can be inserted into the connecting groove 110 along the depth direction of the connecting groove 110, and can be fixedly connected to the first handle 100 by two locking bolts 410.

[0046] like Figures 3 to 8 As shown, when the blade 300 and the first handle 100 are in the second connection mode, the first handle 100 is connected to the blade 300, and the second opening 112 of the connecting groove 110 faces the second handle 200. The cutting edge 321 of the blade 300 can pass through the first set of wire holes 2121 and cut the pipeline passing through the first set of wire holes 2121. In this state, the connecting part 310 of the blade 300 can be inserted into the connecting groove 110 along the direction from the first opening 111 to the second opening 112, and the end of the connecting part 310 away from the cutting part 320 can protrude relative to the side of the first handle 100 facing the second opening 112. The connecting part 310 can be fixedly connected to the first handle 100 by a locking bolt 410. In addition, the end wall of the first opening 111 facing the first end 101 can abut against the side of the connecting part 310 away from the second handle 200, and the protrusion 323 can abut against the side of the first handle 100 away from the second handle 200. Therefore, when the user holds the first handle 100 and the second handle 200 to perform a cutting action, the first handle 100 can also apply more force to the blade 300 so that the blade 300 can smoothly cut the pipeline passing through the first set of wire holes 2121.

[0047] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in some embodiments, the wire cutter 1000 further includes an elastic element 600, which can be connected between the blade 300 and the second handle 200. The elastic element 600 can be used to drive the wire cutter 1000 from a closed state 1002 to an open state 1001. That is, when the blade 300 is in the wire cutting hole 211, the elastic element 600 can drive the end of the blade 300 away from the first handle 100 to protrude relative to the side of the second handle 200 opposite to the first handle 100.

[0048] In some embodiments, the elastic element 600 may be a tension spring. A receiving groove 221 may be provided at one end of the handle portion 220 of the second handle 200 near the operating portion 210. The receiving groove 221 may be located on the side of the second handle 200 facing the first handle 100. The end of the receiving groove 221 facing the operating portion 210 may communicate with the wire cutting hole 211.

[0049] In this embodiment, the elastic element 600 may be disposed in the receiving groove 221. One end of the elastic element 600 may extend into the wire cutting hole 211 and be fixedly connected to the cutting portion 320 of the blade 300. The other end of the elastic element 600 may be fixedly connected to the inner wall of the receiving groove 221 away from the wire cutting hole 211.

[0050] In some embodiments, the shearing portion 320 may have a connecting hole 322 at one end near the connecting portion 310, and the end of the elastic member 600 facing the blade 300 may pass through the connecting hole 322 and be hooked to the blade 300. A pin may be fixedly connected to the inner wall of the receiving groove 221 at the end away from the wire cutting hole 211 by means of screwing or riveting, and the end of the elastic member 600 away from the blade 300 may be hooked to the pin.

[0051] In this embodiment, when the wire cutter 1000 is in the open state 1001, the end of the cutting part 320 near the connecting part 310 can abut against the inner wall of the wire cutting hole 211 near the receiving groove 221, which can limit the opening angle between the blade 300 and the second handle 200, and the elastic element 600 can be in a naturally extended state or a stretched state. Correspondingly, when the wire cutter 1000 is in the closed state 1002, the elastic element 600 can be in a stretched state and store a certain amount of elastic potential energy. When the user removes the force, the blade 300 can rotate and reset under the drive of the elastic element 600, so that the wire cutter 1000 switches to the open state 1001.

[0052] In other embodiments, the elastic element 600 may also be a structure such as an elastic rope or a spring sheet.

[0053] like Figure 1 , Figure 6 and Figure 9 As shown, in some embodiments, the handle 220 may also be a columnar structure. The side of the handle 220 opposite to the first handle 100 may be an arc surface. This improves the user's grip comfort and facilitates cutting operations.

[0054] In other embodiments, the hand grip 220 of the second handle 200 may also be cylindrical in shape for easy gripping by the user.

[0055] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in some embodiments, a locking member 500 is also connected to the end of the handle 220 away from the operating part 210. The locking member 500 can be fixedly connected to the handle 220. In addition, the locking member 500 can be detachably connected to the second end 102 of the first handle 100. Thus, when the wire cutter 1000 is not in use, the wire cutter 1000 can be in a closed state 1002, and the locking member 500 can be connected to the first handle 1000 to keep the wire cutter 1000 in the closed state 1002, which facilitates the storage of the wire cutter 1000 and avoids the safety hazards caused by the exposed blade 300 of the wire cutter 1000. In this case, the blade 300 and the first handle 100 are in the first connection mode.

[0056] In some embodiments, the locking member 500 may be a locking bolt 510. The locking bolt 510 may pass through and be screwed onto the handle portion 220. The locking bolt 510 may protrude from the side of the handle portion 220 facing the first handle 100. The side of the first handle 100 facing the second handle 200 may have an internal threaded hole 120, which may be adapted to the external thread of the locking bolt 510. When the wire cutter 1000 needs to be maintained in the closed state 1002, the user can screw the locking member 500, gradually inserting it into the internal threaded hole 120 and screwing it onto the internal threaded hole 120, so that the first handle 100 and the second handle 200 are closed and relatively fixed. When the wire cutter 1000 is needed, the user can turn the locking part 500 to gradually disengage the locking part 500 from the internal threaded hole 120 until the end of the locking part 500 facing the first handle 100 no longer interferes with the relative rotation of the first handle 100 and the second handle 200.

[0057] In other embodiments, the locking element 500 may also be a snap-fit ​​structure.

[0058] In summary, the wire cutter 1000 provided in this application embodiment may include the following features: (i) By setting a wire hole 212 perpendicular to the wire cutting hole 211 at the operating end of the second handle 200, the wire hole 212 can constrain the pipeline to be cut, so that the part of the pipeline to be cut extends in a straight line, thereby making the cut more flat and burr-free, and improving the cutting effect.

[0059] (ii) By setting multiple inner diameter wire holes 212, the wire cutter 1000 can be used to cut pipes of different diameters, making it more versatile.

[0060] (iii) The connecting groove 110 has openings with different extension lengths on both sides, which allows the blade 300 and the first handle 100 to have two connection modes, so as to realize the cutting of the pipeline in the wire hole 212 at different positions, and to facilitate the user's labor-saving operation.

[0061] (iv) Both the first handle 100 and the second handle 200 are columnar structures, which can utilize the lever principle to achieve a labor-saving effect, making it convenient for users to perform cutting operations and improving cutting efficiency. In addition, the side of the first handle 100 away from the second handle 200 and the side of the second handle 200 away from the first handle 100 are both arc surfaces, which can facilitate the user to apply force to the first handle 100 and the second handle 200, improving the user's grip comfort.

[0062] (v) A locking element 500 is provided at the end of the hand-held part 220 of the second handle 200 away from the operating part 210, which can facilitate the storage of the wire cutter 1000 and improve the safety of the wire cutter 1000 when it is stored.
