[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The veterinary flying needle provided in this application comprises a syringe, a piston, a piston shaft, a piston handle, and an elastic member. One end of the syringe is a needle end for connecting to a needle, and the other end is a barrel end with a barrel opening, through which the piston is inserted into the syringe.

[0039] like Figures 1 to 3As shown, the present application provides a veterinary flying needle, comprising a syringe 1, a piston 2, a piston shaft 3, a piston handle 4 and an elastic member (not shown). Among them, the syringe 1 is made of high-strength transparent plastic material, which not only ensures the durability of the syringe 1 structure, but also makes the internal liquid capacity clear at a glance through its transparent characteristics, which is convenient for precise control. One end of the syringe 1 is a needle end for connecting the needle, and the other end is a barrel end with a barrel mouth, and the piston 2 is inserted into the syringe 1 through the barrel mouth. The inner wall of the syringe 1 has a protrusion 11 so that one end of the elastic member can be hung on the protrusion 11. It should be noted that the setting of the protrusion 11 cannot interfere with the movement of the piston 2. The piston 2 is slidably connected to the inner wall of the syringe 1. At the same time, the piston 2 and the inner wall of the syringe 1 enclose a liquid storage chamber for storing liquid medicine. One end of the piston shaft 3 is connected to the piston 2, and the piston handle 4 is connected to the other end of the piston shaft 3. The piston handle 4 is provided with a slot 41 so that the other end of the elastic member can be hung on the slot 41. The elastic member can specifically be an elastic telescopic element such as a rubber band or a rubber rope. When in use, hold the piston handle 4 and pull out the piston 2 to form a negative pressure in the liquid storage chamber, thereby drawing the medicinal liquid into the liquid storage chamber. At the same time, the elastic member stretches under the tensile action of the piston handle 4 and the protrusion 11, increasing the elastic potential energy. After the veterinary flying needle hits the target, the elastic potential energy released by the elastic member pushes the piston 2 to squeeze out the medicinal liquid. In order to reduce the friction between the syringe 1 and the launch tube (not shown), the axial projection of the elastic member along the syringe 1 is within the axial projection range of the syringe 1, so that the elastic member is always on the inner side of the syringe 1. Therefore, when the veterinary flying needle of the present application is launched, the elastic member will not come into contact with the inner wall of the launch tube, and no friction will be generated, thereby reducing the friction between the syringe 1 and the launch tube and increasing the effective range of the veterinary flying needle of the present application.

[0040] like Figures 1 to 3 As shown, in one embodiment of the present application, the piston shaft 3 has an axially extending receiving groove 31 for accommodating an elastic member. This groove 31 reduces the extrusion and friction between the elastic member and the inner wall of the syringe 1, thereby extending the service life of the elastic member. The groove 31 also ensures that the elastic member remains in the intended position, reducing the impact of its movement on the performance of the veterinary flying needle. Furthermore, the groove 31 facilitates the installation and maintenance of the elastic member.

[0041] In one embodiment of the present application, there are multiple accommodating grooves 31, each of which is arranged sequentially around the axial direction of the syringe 1. This not only achieves a lightweight design in structure, effectively reducing the weight of the entire component, reducing energy consumption and manufacturing costs, but also provides flexibility in the assembly of the elastic member to adapt to different application scenarios and requirements. Under the arrangement of each accommodating groove 31, the radial cross-section of the piston shaft 3 can be a straight line, a cross, or a P-shaped shape.

[0042] like Figures 1 to 3As shown, in one embodiment of the present application, the protrusion 11 extends toward the needle end. Only when the extension direction of the protrusion 11 is opposite to the direction of the pulling force on the elastic member, the protrusion 11 can better hook the elastic member.

[0043] like Figures 1 to 3 As shown, in one embodiment of the present application, the protrusions 11 are arranged in pairs and symmetrically on the inner wall of the syringe 1 to ensure the structural balance of the veterinary flying needle and the installation stability of the elastic member. Specifically, one end of the elastic member is hung on one of the paired protrusions 11, and the other end of the elastic member is hung on the other of the paired protrusions 11. The middle section of the elastic member is clamped in the clamping groove 41 of the piston handle 4, which effectively prevents the elastic member from sliding or falling off during use, and also ensures the continuity of force transmission between the piston handle 4 and the elastic member, thereby improving the working reliability of the entire veterinary flying needle.

[0044] In one embodiment of the present application, the protrusion 11 is an elastic protrusion, and the protrusion 11 and the syringe 1 are integrally formed. This not only simplifies the manufacturing process and reduces production costs, but also improves the stability and durability of the structure. During long-term use, the connection between the protrusion 11 and the syringe 1 is not prone to loosening or breaking due to fatigue or stress concentration. When inserting the piston 2, the protrusion 11 can move away from the outside of the syringe 1 to avoid interference with the piston 2.

[0045] like Figures 1 to 3 As shown, in one embodiment of the present application, the slot 41 is a V-shaped slot. The two side walls of the V-shaped slot are inclined inward, which guides the installation of the elastic member. When the elastic member reaches the predetermined position, the two side walls can restrain the elastic member and prevent it from falling out of the slot 41.

[0046] In one embodiment of the present application, the veterinary flying needle further includes a tail wing 5. The tail wing 5 is mounted over the elastic member, but does not affect the normal function of the elastic member. The tail wing 5 is formed by folding multiple strands of 8.0 cm woolen cord in the middle and then tying them together at the folded portion. The tail wing 5 serves as a marker. After the veterinary flying needle is fired, the tail wing 5 clearly indicates the specific impact location for easy observation.

[0047] like Figure 4 As shown, in one embodiment of the present application, the veterinary flying needle further comprises a needle connecting barrel 6. The needle connecting barrel 6 is disposed at the needle end of the syringe 1 and has threads formed on its inner wall for threaded connection with the needle. The presence of the threads not only increases the contact area and improves the stability of the connection, but also effectively prevents the needle from loosening or falling off due to external forces during use through the friction generated during tightening.

[0048] In one embodiment of the present application, the veterinary flying needle further comprises a needle (not shown). The needle is detachably connected to the needle end of the syringe 1. This ensures a stable connection between the needle and the syringe 1 while facilitating quick and easy removal when the needle needs to be replaced or cleaned. Specific detachable connection methods include, but are not limited to, plug-in, snap-on, and threaded connections.

[0049] The above description is only a preferred embodiment 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 should be included in the scope of protection of the present application.
