Description

Technical Field

[0001] This invention relates to a veterinary instrument, and more particularly to an ear tag clamp. Background Technology

[0002] To facilitate the tracking of livestock breeds, origins, and disease prevention status, ear tags are typically attached to their ears. Ear tagging pliers are the instruments used to attach these tags. However, existing ear tagging pliers cause significant pain and discomfort to livestock during the tagging process, easily startling them and making the process inconvenient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an ear tag clamp that overcomes the shortcomings of the prior art and reduces the pain and discomfort of livestock during the ear tag installation process.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows.

[0005] An ear tag pliers includes a base, a slide bar vertically fixed on the base, a marking head slidably mounted on the slide bar, the marking head being connected to the base via a first spring, the spring being sleeved on the outside of the slide bar, a retaining ring fixed on the top surface of the base, a semiconductor cooling chip being installed inside the retaining ring, a downwardly inclined beveled portion being provided on the inner edge of the top surface of the retaining ring, and a soft pad being provided on the top surface of the retaining ring.

[0006] Preferably, the retaining ring has several mounting holes inside. One end of the mounting hole is connected to the inclined surface, and the other end is connected to the top surface of the retaining ring. A core post is movably mounted in the mounting hole, with one end of the core post located on the outer side of the inclined surface. The core post is connected to the mounting hole via a second spring. A support rod is movably mounted in the mounting hole. A first groove is provided at the connection between the mounting hole and the top surface of the retaining ring. One end of the support rod is located on the outer side of the first groove. A second groove corresponding to the first groove is provided on the soft pad. The support rod is connected to the mounting hole via a third spring. A sliding contact inclined surface is provided at the contact end between the core post and the support rod. When the core post is pressed downward, the core post pushes the support rod to move outward towards the retaining ring.

[0007] Preferably, the end face edge of the core post located outside the mounting hole is provided with a notch, and the inner edge of the notch is provided with a flexible toothed portion.

[0008] Preferably, a rubber pad is provided on the end face of the support rod located outside the mounting hole.

[0009] Preferably, a first elastic limiting piece is fixed to the inner wall of the retaining ring, which is used to limit the installation of the ear tag.

[0010] Preferably, the marking head is provided with an earring hole, a top cover is slidably provided on the top of the earring hole, and a second elastic limiting piece is provided on the bottom of the earring hole.

[0011] The beneficial effects of adopting the above technical solution are as follows: the retaining ring of the present invention is used to install tags, and the marking head is used to install ear studs. By installing a semiconductor cooling chip inside the retaining ring, local low-temperature treatment of the ear is achieved to reduce nerve sensitivity, thereby reducing the pain and discomfort of livestock during ear tag installation. At the same time, by optimizing the retaining ring structure, uneven force on the ear is reduced during the compression and puncture process, thereby further reducing discomfort.

[0013] Figure 2 This is a longitudinal cross-sectional view of the retaining ring in a specific embodiment of the present invention.

[0014] Figure 3 This is a structural diagram of the notch at the outer end of the core post according to a specific embodiment of the present invention.

[0015] Figure 4 This is a magnified view of the interior of the notch in one specific embodiment of the present invention. Detailed Implementation

[0016] Existing ear tagging pliers include a base 1, on which a slide rod 2 is vertically fixed. A tagging head 3 is slidably mounted on the slide rod 2, and the tagging head 3 is connected to the base 1 via a first spring 4, which is sleeved on the outside of the slide rod 2. Through extensive research, the inventors discovered that existing ear tagging pliers apply unreasonable pressure to the animal's ear during use, causing significant discomfort and making the animal easily startled. To address this issue, the inventors have optimized and upgraded the design of the retaining ring placed below the ear, as detailed below.

[0017] A retaining ring 5 is fixed to the top surface of the base 1. The inner edge of the top surface of the retaining ring 5 is provided with a downwardly inclined bevel 7, and a soft pad 8 is provided on the top surface of the retaining ring 5. The soft pad 8 prevents the ear from being squeezed between it and the retaining ring 5. The bevel 7 can make the outer side of the puncture site fit against the bevel 7 and be tilted when the marking head 3 presses down on the ear, thereby reducing the pulling force perpendicular to the ear tissue on the puncture site during the puncture process.

[0018] The retaining ring 5 has several mounting holes 9 inside. One end of the mounting hole 9 is connected to the inclined surface 7, and the other end of the mounting hole 9 is connected to the top surface of the retaining ring 5. A core post 10 is movably installed in the mounting hole 9. One end of the core post 10 is located outside the inclined surface 7. The core post 10 is connected to the mounting hole 9 through a second spring 11. A support rod 12 is movably installed in the mounting hole 9. A first strip groove 13 is provided at the connection between the mounting hole 9 and the top surface of the retaining ring 5. One end of the support rod 12 is located outside the first strip groove 13. A second strip groove 14 corresponding to the first strip groove 13 is opened on the soft pad 8. The support rod 12 is connected to the mounting hole 9 through a third spring 15. A sliding contact inclined surface 16 is provided at the contact end between the core post 10 and the support rod 12. When the core post 10 is pressed downward, the core post 10 pushes the support rod 12 to move outward of the retaining ring 5. During the puncture, the ear, which is attached to the bevel 7, is compressed, which in turn compresses the top of the core 10, causing the core 10 to push the support rod 12 to tilt outward, thereby flattening the outer side of the ear and avoiding uneven force on the outer side of the ear.

[0019] The core post 10 has a notch 17 on its outer edge of the mounting hole 9, and a flexible toothed portion 18 is provided on the inner edge of the notch 17. The notch 17 serves as a buffer to prevent excessive pulling of the ear by the core post 10 and the retaining ring 5. The flexible toothed portion 18 supports and limits the ear tissue located at the notch 17, preventing the ear tissue from getting stuck or crushed within the notch 17. A reinforcing block 24 is provided at the bottom of the notch 17, and a support frame 25 connects the flexible toothed portion 18 and the reinforcing block 24. The support frame 25 is filled with a flexible buffer layer 26. By supporting and reinforcing the flexible toothed portion 18, the stability of the flexible toothed portion 18 under force can be ensured, thereby ensuring the uniformity of force on the ear. The flexible buffer layer 26 is used to protect the ear tissue entering the notch 17. A rubber pad 19 is provided on the outer edge of the support rod 12 of the mounting hole 9 to prevent the support rod 12 from directly contacting and rubbing against the ear, which would cause discomfort.

[0020] In addition, a semiconductor cooling chip 6 is installed inside the clasp 5. The low temperature treatment reduces the sensitivity of the auditory nerve, thereby reducing the discomfort during the puncture process.

[0021] A first elastic limiting piece 20 is fixed to the inner wall of the retaining ring 5, which is used to limit the installation of the ear tag. The marking head 3 has an earring hole 21, a top cover 22 is slidably mounted on the top of the earring hole 21, and a second elastic limiting piece 23 is mounted on the bottom of the earring hole 21. When installing the ear tag, open the top cover 22, insert the earring into the earring hole 21, and hold the earring in place against the second elastic limiting piece 23. Then close the top cover 22, install the ear tag below the first elastic limiting piece 20, place the ear between the retaining ring 5 and the marking head 3, press down on the top cover 22 to allow the earring to pass through the ear and secure it to the ear tag, then release the pressure. The marking head 3 rises under the rebound of the first spring 4, the earring disengages from the second elastic limiting piece 23, and then the animal's ear is moved away, causing the ear tag to disengage from the first elastic limiting piece 20, thus completing the ear tag installation.
