/ 18 Highly adaptable ear tag marking brush for animals. Field of invention

[001] This utility model patent comprises a highly adaptable manual brush for marking animal ear tags, belonging to the technical area of ​​veterinary instruments, with the advantage of not piercing the animal's ear when applying the tag. Fundamentals of the invention

[002] In the area of ​​animal husbandry management, animal identification tags are widely used as an important identification tool in various livestock species. At the same time, the tag applicator, as a specialized instrument for installing tags, its structure and adaptability with the tags.

[003] Taking as an example a cow ear tag disclosed in existing technology (Authorized Publication Number CN202112139U), the design of this ear tag meets, to some extent, the basic needs of use. Its structure includes a sub-ear tag, an ear tag plate, and a chip. The upper part of the ear tag plate has a projecting blade, in the middle of which there is a perforated hole. Around the perforated hole, there is a sheath, and there is a gap between the lower part of the inner wall of the sheath and the opening of the perforated hole. In the center of the ear tag plate, there is an embedded chip. As shown in Figure 1, the structure of the ear tag plate, which has the structure of the sheath, is presented. This design, by embedding the chip in the ear tag plate, effectively prevents damage to the chip during use, and the sheath prevents the tip of the ear tag from piercing the cow, ensuring, to some extent, the safety of the animal and the integrity of the ear tag.

[004] However, earring plates designed by different manufacturers have different shapes, and the heights of the sheaths on the earring plates also vary. Petition 870250065300, dated 07 / 28 / 2025, page 19 / 39 / 18 This design flaw leads to many inconveniences in practical application. When the ear tag is used in conjunction with the ear tag applicator, the sheath is inserted into the groove of the applicator's mouth. However, due to height differences, a stable insertion cannot be guaranteed. This can lead to fluctuations or displacements between the ear tag and the applicator during tagging, impairing the effect and efficiency of the tagging. For example, when tagging a cow, due to the instability of the ear tag, it may be necessary to adjust it several times to apply it successfully. This not only increases the workload of the employees but can also prolong the tagging time, reducing work efficiency. What is more serious, this unstable application can cause unnecessary harm to the animal, such as scratches or punctures in the ear, affecting the animal's health and well-being.

[005] Searching the Brazilian and international patent databases revealed the following findings.

[006] The object of patent BR 11 2023 020598 0 describes an animal tag applicator composed of two articulated body portions, each with a claw for attaching the tag, a handle and a central part, joined by a fixing bushing. Even though it is efficient, it is still an invasive method, which generates pain, risk of infection and stress in the animal, due to the perforation of the animal's ear.

[007] Patent CN216219477U describes an ear tag applicator with automatic spring return, designed to facilitate animal identification. The device consists of a main rod and an auxiliary rod, both with gripping and fixing parts for the tag (ear tag) and equipped with specific grooves for fitting components. A return spring assembly allows the applicator to automatically return to its initial position after use, while a limiter system ensures movement control. There are also elastic pressure parts to ensure stability and safety. Petition 870250065300, dated 07 / 28 / 2025, page 20 / 39 / 18 during the application of the ear tag. As with other applicators, the device still pierces the animal's ear, which can cause pain, stress, and risk of infection.

[008] Patent PI 1010947-1 describes a mechanical applicator for animal tags, with a system of two handles and two jaws that move together. The major difference lies in a linking mechanism with two articulated arms that pass through a resting position. When the user squeezes the handles, the jaws close to pierce and apply the tag; by continuing to squeeze beyond the central point, the jaws automatically reopen. This is possible thanks to a set of springs that maintain the standard opening of the jaws. The aim is to facilitate use, improve efficiency and reduce operator fatigue by eliminating the need for manual opening after each application.

[009] Patent CN216219477U discloses an ear tag applicator with automatic return. Its structural design aims to increase the practicality and efficiency of the tagging operation. This ear tag applicator includes a main post, a secondary post, a component for the male ear tag fixing pin, a component for the elastic pressure blade, a return component, and a limit component. The first pressing part of the main post has a groove for installing the male ear tag fixing pin in the inner position near the end, and the second pressing part of the secondary post has a groove for installing the elastic pressure blade and a through hole for the male ear tag fixing pin in the inner position near the end. This design allows the ear tag to be quickly positioned and fixed by means of the elastic pressure blade component during application.

[010] However, when this earring applicator is used in conjunction with existing earrings, due to the design of the applicator's mouth groove based on certain standard dimensions and the height differences of the existing earring sheaths, the earring cannot achieve an ideal stable state when inserted. Petition 870250065300, dated 07 / 28 / 2025, page 21 / 39 / 18 in the groove of the applicator mouth. Although the elastic pressure blade component can provide some pressure, due to differences in the height of the sheaths, this pressure cannot be applied uniformly to the ear tag, causing the ear tag to be prone to oscillation or displacement during marking. Furthermore, although the design of the return component allows for the automatic return of the ear tag applicator, in the event of instability during ear tag installation, the advantages of this feature are difficult to fully utilize. It may even cause damage or failure of the ear tag applicator due to the ear tag falling off.

[011] In summary, there is an apparent incompatibility in the combination between existing ear tags and ear tag applicators. Differences in sheath height on ear tag plates lead to unstable insertion when combined with ear tag applicators, resulting in a number of problems such as low marking efficiency, increased risk of animal injury, and increased equipment failure rate. These problems not only affect the normal functioning of animal husbandry management but also represent a potential threat to animal health and welfare.

[012] Therefore, an improvement plan is urgently needed to address the problem of insertion instability caused by differences in sheath height when existing ear tags and ear tag applicators are combined, increase the stability and reliability of ear tag use, ensure the success of the marking operation, and at the same time guarantee the health and safety of the animals.

[013] In view of this, this utility model provides an applicator for attaching ear tags to animals with high adaptability, aiming to solve the aforementioned technical problems.

[014] To achieve this objective, this utility model adopts the following technical scheme: an applicator for attaching ear tags to animals with high Petition 870250065300, dated 07 / 28 / 2025, page 22 / 39 / 18 adaptability comprises: the first part of the applicator mouth, used to hold the earring plate, and which extends integrally with the first catch loop; the second part of the applicator mouth, used to install the earring fixing male pin component.

[016] The first part of the applicator mouth, on the jaw furthest from the connecting transition part, has a groove for fitting the female part of the earring. The base of the groove for fitting the female part of the earring has a through relief opening for the head of the male earring fastening pin.

[017] In addition, it includes a removable positioning compensation block connected within the fitting groove of the female part of the ear tag.

[018] The positioning compensation block includes a coupling part and a positioning part. The coupling part is inserted into the relief opening, and the positioning part is inserted into the fitting groove of the female part of the ear tag. The positioning part has a positioning opening corresponding to the male ear tag fastener pin component, and the base of the positioning opening has a through hole for the head of the male ear tag fastener pin.

[019] Through this technical scheme, this utility model configures a removable positioning compensation block, which can adapt to earring sheaths of different heights, solving the problem of instability. Petition 870250065300, dated 07 / 28 / 2025, page 23 / 39 / 18 of the insertion caused by the variation in heights of the earring sheaths in existing technology, making the combination between the earring applicator and various types of earring more stable and reliable. The design of the positioning opening and the hole of the positioning compensation block provides precise positioning for the male pin component of the earring, ensuring that the earring does not oscillate or move during marking, improving the marking effect and efficiency.

[029] Through the aforementioned technical schemes, in comparison with existing technology, this utility model discloses an applicator for attaching ear tags to animals with high adaptability, with the following beneficial effects:

[030] With the configuration of the removable positioning compensation block, it is possible to adjust according to the different heights of the ear tag sheaths, effectively solving the problem of insertion instability caused by the inconsistency of the ear tag sheath height in existing technology. This makes the combination between the ear tag applicator and various types of ear tags more stable and reliable, significantly increasing the stability and reliability of ear tag use. The design of the positioning opening and the hole of the positioning compensation block provides precise positioning for the male pin component of the ear tag, ensuring that the ear tag does not wobble or move during marking, improving the marking effect and efficiency and ensuring the success of the marking operation. Petition 870250065300, dated 07 / 28 / 2025, page 27 / 39 / 18

[031] The design of the bar return section and control component enables the automatic return function of the ear tag applicator. After the marking operation is complete, the applicator mouth can be automatically opened, eliminating the need for manual opening, significantly increasing the practicality and efficiency of the operation and reducing the workload for employees. The limit section configuration can stably connect the first and second picking handles during marking, preventing the handles from shifting or coming loose during operation. Furthermore, the design of the friction textures on the outer surfaces of the handles increases grip, allowing employees to hold the ear tag applicator more firmly. Even with wet or oily hands, it is possible to effectively prevent the handle from slipping, further increasing the stability and safety of the operation.

[032] The coupling part and the positioning part are integrally molded and form an X-shaped structure. This design makes the connection between the positioning compensation block and the fitting groove of the female part of the ear tag firmer, increasing the stability of the integral structure and facilitating the installation and removal of the positioning compensation block. The return part of the bar consists of a first arched elastic blade and a second arched elastic blade articulated to each other. The configuration of the first tension spring and the first spring provides a stable return force for the return part of the bar, making the return movement more flexible and smooth and better able to adapt to different marking forces and operating rhythms, increasing the adaptability and service life of the ear tag applicator.

[033] Due to the significantly increased adaptability between the ear tag applicator and the ear tag, the ear tag does not move away or shift during marking, reducing the time required for multiple adjustments caused by ear tag instability, effectively improving marking efficiency and reducing employee workload. The stable marking process reduces Petition 870250065300, dated 07 / 28 / 2025, page 28 / 39 / 18 the risk of scratches or punctures in the animal's ear, ensuring the animal's health and well-being and avoiding additional medical costs and production losses caused by injury to the animal.

[034] The removable connection of the positioning compensation block gives it greater universality, allowing it to accommodate larger ear tag plates, making the ear tag applicator applicable to different types of livestock and different animal husbandry management scenarios, increasing market competitiveness and product practicality. The design and connection method of each component facilitate maintenance and replacement. For example, the removable design of the positioning compensation block allows it to be quickly replaced or adjusted when necessary, reducing maintenance costs and time and extending the lifespan of the ear tag applicator.

[039] The second pickup loop (4) is used in conjunction with the first pickup loop (2). The end of the second pickup loop (4) is articulated with the connecting transition part (21) and is articulated at the same point as the second part of the applicator mouth (3).

[040] The first part of the applicator mouth (1), in the jaw distant from the connection transition part (21), has a groove for fitting the female earring part (11). The base of the groove for fitting the female earring part (11) has a through relief opening for the head of the male earring fixing pin (6).

[041] In addition, it includes a positioning compensation block (13) connected in a removable manner within the fitting groove of the female part of the ear tag (11).

[042] The positioning compensation block (13) includes a coupling part (131) and a positioning part (132). The coupling part (131) is inserted into the relief opening (12), and the positioning part (132) is inserted into the fitting groove of the female ear tag part (11). The positioning part (132) has a positioning opening (1321) corresponding to the male ear tag fixing pin component (6), and the base of the positioning opening (1321) has a through hole (1322) for the head of the male ear tag fixing pin (6).

[043] To further optimize the above technical scheme, the coupling part (131) and the positioning part (132) are integrally molded. The cross-section of the coupling part (131) is T-shaped, and the positioning part (132) is formed by a lower wall of the positioning part (1323) and three connected side walls of the positioning part (1324). The lower wall of the positioning part (1323) and the coupling part (131) form a Petition 870250065300, dated 07 / 28 / 2025, page 31 / 39 / 18 X-structure. The core of the X-structure (1311) is inserted into the relief opening (12), and the upper and lower bracts of the X-structure fasten the upper and lower surfaces of the lower wall of the fitting groove of the female part of the ear tag (11).

[044] To further optimize the above technical scheme, the orifice (1322) passes through the coupling part (131) and the positioning part (132).

[045] To further optimize the above technical scheme, the edge of the lower wall of the positioning opening (1321) has a positioning step surface (1325).

[046] According to figures 7 and 10 to 11, the first part of the applicator mouth (1) is connected to a part of the elastic pressure blade (14) used to hold the earring plate (7). The part of the elastic pressure blade (14) is used to hold the earring plate (7) whose sheath (71) is inserted into the fitting groove of the female part of the earring (11) or into the positioning opening (1321).

[047] The elastic pressure blade part (14) includes a pressure blade (141) and a second spring (142). The pressure blade (141) is articulated with the first part of the applicator mouth (1).

[048] According to figures 7 to 9 and 12, the end of the second part of the applicator mouth (3) distant from the earring fixing male pin component (6) and the second pickup loop (4) are connected by a return bar part (5). The first pickup loop (2) is connected to a control component (22). When the first pickup loop (2) and the second pickup loop (4) control the closing of the first part of the applicator mouth (1) and the second part of the applicator mouth (3), the return bar part (5) moves together. When the first part of the applicator mouth (1) and the second part of the applicator mouth (3) complete the closing and marking, the control component (22) pushes the return bar part (5), causing the second part of the applicator mouth (3) to move away from the first part of the applicator mouth (1) and opening the applicator mouth.

[049] To further optimize the above technical scheme, the return part of the bar (5) includes a first arched elastic blade (51) and a second arched elastic blade (52) articulated to each other. The end of the first arched elastic blade (51) distant from the second arched elastic blade (52) is articulated with the end of the second part of the applicator mouth (3) distant from the earring fixing male pin component (6), and the end of the second arched elastic blade (52) distant from the first arched elastic blade (51) is articulated with the second catch handle (4).

[050] To further optimize the above technical scheme, a first tension spring (23) is connected between the first arched elastic blade (51) and the first pickup loop (2), and a first spring (41) is coupled between the second arched elastic blade (52) and the second pickup loop (4).

[051] In this implementation example, the control component (22) includes a nut (221) that passes through the first pickup loop (2). The nut (221) is threaded into the first pickup loop (2). The nut head (2211) of the nut (221) is located inside the first pickup loop (2). Petition 870250065300, dated 07 / 28 / 2025, page 33 / 39 / 18 and is used to counteract the second arched elastic blade (52). The other end of the nut (221) passes through the first catch loop (2) and is connected to a nut cap (222). This structure facilitates the installation and adjustment of the position of the nut (221).

[052] According to figure 12, to facilitate connection, a first articulation axis (26) is fixed inside the first catch handle (2). One end of the first tension spring (23) is hooked onto the first articulation axis (26), and the other end is hooked onto a hole in the first arched elastic blade (51).

[053] To meet the limit angle of the applicator mouth opening, a locking pin (53) is also connected to the second arched elastic blade (52). The locking pin (53) is used to counteract the first arched elastic blade (51).

[054] To further optimize the above technical scheme, the second pickup loop (4) is connected to a limit part (42) used to connect with the first pickup loop (2).

[055] The limit part (42) includes a second articulation axis (421) fixed inside the second pickup handle (4). A hook (423) is connected to the second articulation axis (421) via a torsional spring (422). The hook (423) is used to hook onto the first articulation axis (26).

[056] To further optimize the above technical scheme, the outer surfaces of the first pickup handle (2) and the second pickup handle (4) have friction textures (24).

[057] To further optimize the above technical scheme, a first contact button (25) is fixed to the first pickup handle (2), and a second contact button (43) that combines with the first contact button (25) is fixed to Petition 870250065300, dated 07 / 28 / 2025, page 34 / 39 / 18 second pickup handle (4). The first contact button (25) and the second contact button (43) are made of rubber.

[058] According to figure 12, a third articulation axis (32) is fixed inside the second part of the applicator mouth (3), close to the end of the connection transition part (21). The connection end of the earring fixing male pin component (6) with the second part of the applicator mouth (3) has a hook hole. A second tension spring (31) is connected between the hook hole and the third articulation axis (32).

[059] According to figures 13 to 16, the diagrams show the state of use of the applicator for attaching ear tags with high adaptability provided by this implementation example. The use of the positioning compensation block (13) depends on the height of the sheath (71) of the ear tag plate (7). When the height of the sheath (71) can match the fitting groove of the female part of the ear tag (11), it is not necessary to add the positioning compensation block (13). When the height of the sheath (71) is insufficient to match the fitting groove of the female part of the ear tag (11), it is necessary to add the positioning compensation block (13). The removable connection of the positioning compensation block (13) gives it greater universality, being able to accommodate the use of ear tag plates (7) of more dimensions.

[060] During the use of the ear tag applicator in this implementation example: People manually hold the first catch handle (2) and the second catch handle (4) and press them. The first part of the applicator mouth (1) and the second part of the applicator mouth (3) approach each other to perform the marking operation. When the first part of the applicator mouth (1) and the second part of the applicator mouth (3) close and complete the marking, the nut head (2211) of the nut (221) gradually opposes the second arched elastic blade (52) and creates a pressure tendency, causing the Petition 870250065300, dated 07 / 28 / 2025, page 35 / 39 / 18 second arched elastic blade (52) rotate and cause the first arched elastic blade (51), which is articulated to it, to rotate. Then, with the action of the first tension spring (23), the second part of the applicator mouth (3) moves away from the first part of the applicator mouth (1) and returns to its original position, performing the automatic return function.
