[0038] Unless otherwise defined, all professional terms used herein have the same meaning as understood by a person skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the utility model.

[0039] As shown in Figures 1 to 3 The utility model provides a veterinary flying needle tool forceps, including first forceps arm 1, second forceps arm 2, cutter head 3 and cutter groove 4. Wherein, first forceps arm 1 includes first forceps mouth part 11 and first forceps handle part 12. Second forceps arm 2 is crossed with first forceps arm 1 and is hinged to connect with first forceps arm 1, to make first forceps arm 1 and second forceps arm 2 can complete open and close action. Second forceps arm 2 includes second forceps mouth part 21 and second forceps handle part 22. By pressing first forceps handle part 12 and second forceps handle part 22, first forceps mouth part 11 and second forceps mouth part 21 close, on the contrary, when first forceps handle part 12 and second forceps handle part 22 are away from each other, first forceps mouth part 11 and second forceps mouth part 21 open. Cutter head 3 is connected to first forceps mouth part 11, and cutter groove 4 is arranged on second forceps mouth part 21. The veterinary flying needle tool forceps of the utility model is used to set needle tube wall between cutter head 3 and cutter groove 4, drive first forceps mouth part 11 and second forceps mouth part 21 close, so that cutter head 3 penetrates needle tube wall and extends into cutter groove 4, thereby clamping corresponding opening on needle tube wall.

[0040] As shown in Figure 4As shown, in one embodiment of the present application, the cutter head 3 includes a bottom plate portion 31 and a vertical blade portion 32. The bottom plate portion 31 is the base portion of the cutter head 3, and the bottom plate portion 31 is used to provide sufficient support area to ensure the stability of the connection between the cutter head 3 and the first jaw portion 11. One end of the vertical blade portion 32 is connected to the bottom plate portion 31, and the vertical blade portion 32 extends in a direction perpendicular to the bottom plate portion 31 so that the vertical blade portion 32 has sufficient length to penetrate the needle tube wall. The other end of the vertical blade portion 32 is a blade, and the projection of the blade on the bottom plate portion 31 is U-shaped, and the shape of the blade corresponds to the shape of the opening to be opened on the needle tube wall. The open end of the U-shaped blade faces the first jaw portion 12, and the closed end of the U-shaped blade faces the tip of the first jaw portion 11. Under the shearing action of the U-shaped blade, a U-shaped incision is formed on the needle tube wall.

[0041] In one embodiment of the present application, the plane where the blade is located is arranged at an angle to the bottom plate portion 31, so that the blade can cut obliquely into the needle tube wall, thereby reducing the shear resistance of the blade during the shearing process.

[0042] In one embodiment of the present application, the angle between the plane where the blade is located and the bottom plate portion 31 is in the range of 0°-±15°.

[0043] like Figures 1 to 3 As shown, in one embodiment of the present application, the jaw surface of the second jaw portion 21 is an outwardly convex arc surface. This arc surface is required to conform to the curved surface of the needle tube wall to reduce the gap between the second jaw portion 21 and the needle tube wall, thereby ensuring a more uniform shear force on the needle tube wall. In addition, a blade groove 4 is also provided on this arc surface to correspond to the blade head 3.

[0044] like Figures 1 to 3 As shown, in one embodiment of the present application, the veterinary flying needle tool pliers further includes a reset spring 5. One end of the reset spring 5 is connected to the first pliers handle portion 12, and the other end of the reset spring 5 is connected to the second pliers handle portion 22. When the first pliers handle portion 12 and the second pliers handle portion 22 are pressed together, the reset spring 5 is compressed and stores elastic potential energy, and the first pliers mouth portion 11 and the second pliers mouth portion 21 are closed, cutting a corresponding opening on the needle tube wall. After the cutting opening is completed, the pressure on the first pliers handle portion 12 and the second pliers handle portion 22 is released, the elastic potential energy of the reset spring 5 is released, and the first pliers handle portion 12 and the second pliers handle portion 22 are pushed back to their initial positions.

[0045] In one embodiment of the present application, the veterinary flying needle tool forceps further comprises a fastener (not shown in the figure). The fastener is connected to the bottom plate part 31 and the first jaw part 11, so that the blade head 3 is detachably connected to the first jaw part 11. The fastener not only ensures the stability of the connection between the bottom plate part 31 and the first jaw part 11, but also facilitates the disassembly and replacement of the blade head 3. When the blade head 3 needs to be replaced or maintained, the locking of the bottom plate part 31 and the first jaw part 11 by the fastener is released, so that the blade head 3 is easily detached from the first jaw part 11. Then, a new blade head 3 is installed in place, and the connection between the bottom plate part 31 and the first jaw part 11 is re-locked by the fastener to ensure that the tool forceps can continue to work normally. The fastener can be a screw or the like.

[0046] As shown in Figures 1 to 3 In one embodiment of the present application, the length of the first jaw part 11 is greater than the width of the first jaw part 11, and the length of the second jaw part 21 is greater than the width of the second jaw part 21. Under this size condition, the first jaw part 11 and the second jaw part 21 have a more elongated contour, so as to facilitate the first jaw part 11 and the second jaw part 21 to extend to different depth positions of the needle tube wall, and also make the first jaw part 11 and the second jaw part 21 can adapt to the needle tube walls of various models such as 3ml, 5ml, 10ml, etc.

[0047] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
