As shown in fig. 1-14, the present invention provides a laboratory mouse ear tag holder comprising a first inlay 100 and a second inlay 200 hingedly connected to each other at their middles. The first inlay 100 includes a first pincer tip 110 at the left end and a first pincer handle 120 at the right end, the second inlay 200 includes a second pincer tip 210 at the left end and a second pincer handle 220 at the right end, and a third spring 300 for keeping the first pincer tip 110 and the second pincer tip 210 in an open state is fixedly installed between the first pincer handle 120 and the second pincer handle 220.

The above-mentioned laboratory mouse ear tag pincers further include ear tag box 400, ear tag assembly 500, pushing mechanism 600 and supporting mechanism 700.

The first jaw 110 has a first through hole 111, and the ear tag box 400 is fixedly mounted right below the first through hole 111. Specifically, the ear tag case 400 is installed under the first jaw 110, and the top end thereof is fixedly connected to the lower side of the first jaw 110. The ear tag box 400 is provided with a tag storage cavity 410, and the tag storage cavity 410 is adapted to the first through hole 111 and is communicated with the first through hole 111. Specifically, the accommodation of the label storage cavity 410 with the first through hole 111 means that the length and width of the label storage cavity 410 are adapted to the length and width of the first through hole 111.

The number of the ear tag assemblies 500 is multiple, and the multiple ear tag assemblies 500 are slidably placed in the first through hole 111 and/or the tag storage chamber 410 and can slide out from the top end of the first through hole 111. In use, the ear tag assemblies 500 are sequentially placed into the first through-hole 111 and/or the tag storage chamber 410 one by one through the top end of the first through-hole 111.

The pushing mechanism 600 is installed on the ear tag box 400 and is used for sequentially pushing the ear tag assemblies 500 in the ear tag box 400 to the top end of the first through hole 111. Specifically, when one ear tag assembly 500 is used, the pushing mechanism pushes the next ear tag assembly 500 to the top end of the first through hole 111.

The supporting mechanism 700 is mounted on the first jaw 110 and the second jaw 210, and is used for supporting the ear tag assembly 500 pushed to the top end of the first through hole 111 by the pushing mechanism 600. When the ear tag is to be attached by using the first inlay 100 and the second inlay 200, the ear tag assembly 500 located at the top end of the first through hole 111 does not transmit a force to the ear tag assembly 500 located therebelow by the supporting mechanism 700, thereby preventing damage to the ear tag assembly 500 located therebelow during attachment of the ear tag.

When in use, the ear tag assembly 500 is firstly put into the first through hole 111 and/or the tag storage cavity 410 through the top of the first through hole 111; then, pushing an ear tag assembly 500 to the top end of the first through hole 111 by using a pushing mechanism and supporting the ear tag assembly by using a supporting mechanism 700; then, the first handle 120 and the second handle 220 are squeezed by hand to complete the binding of the ear tag. The above-described operations are repeated, thereby completing the binding of the plurality of ear tags.

As shown in fig. 12-13, in one embodiment, the ear tag assembly 500 includes a target plate 510 and an ear tag I520 removably connected to the target plate 510.

Wherein the width of the target plate 510 is greater than the width of the ear tag I520 so that the support plate 710 moves below the bottom of the ear tag I520 to support the ear tag I520. And the target plate 510 is adapted to the first through hole 111 and/or the label storage chamber 410. Specifically, the adaptation of the label bearing plate 510 to the first through hole 111 and/or the label storage cavity 410 means that the length and width of the label bearing plate 510 are adapted to the length and width of the first through hole 111 and/or the label storage cavity 410, so that the ear tag assembly 500 is not turned inside the label storage cavity 410 when the ear tag assembly 500 is placed.

In use, the ear tag I520 is first mounted on the tag plate 510, and the ear tag assembly 500 is then placed into the ear tag I520 box 400.

This configuration, by providing a target plate 510, facilitates support of the ear tag assembly 500 during ear tag I520 attachment.

In one embodiment, the top of the target plate 510 is provided with a plurality of positioning posts 511, and the bottom of the ear tag I520 is provided with positioning holes 521 corresponding to the plurality of positioning posts 511 one by one. The ear tag I520 is detachably connected with the label bearing plate 510 through the interference fit of the positioning hole 521 and the positioning column 511. It should be noted that the interference fit here is only a simple detachable connection of the target plate 510 and the ear tag I520, and the target plate 510 and the ear tag I520 can be detached with a slight force, rather than a fixed connection that cannot be detached of the target plate 510 and the ear tag I520.

Through set up reference column 511 and locating hole 521 on bearing mark board 510 and ear tag I520 respectively to ear tag I520 is fixed so that ear tag I520 is beaten to the position on bearing mark board 510, and simultaneously, can also set a plurality of reference columns 511 and a plurality of locating hole 521 to asymmetric structure so that prevent staying in ear tag I520.

However, the above-described ear tag assembly 500 has a disadvantage in that the ear tag II is first mounted on the tag bearing plate 510 before the ear tag assembly 500 is placed in the tag storage chamber 410, and the overall height of the ear tag assembly 500 is increased by the addition of the tag bearing plate 510, thereby reducing the number of ear tag assemblies 500 that can be stored in the tag storage chamber 410. As shown in fig. 14, in one embodiment, the ear tag assembly 500 includes an ear tag II530, the bottom of the ear tag II530 being compatible with the first through-hole 111 and the tag storage chamber 410. In particular, the adaptation of the bottom of the ear tag II530 to the first through hole 111 and/or the tag cavity 410 means that the length and width of the bottom of the ear tag II530 of the first through hole 111 and/or the length and width of the tag cavity 410 are adapted to prevent the ear tag II530 from flipping over within the tag cavity 410. And the width of the bottom of the ear tag II530 is greater than the width of the top of the ear tag II530 to facilitate movement of the support plate 710 below the bottom of the ear tag II530 to support the ear tag II 530.

With this construction of the ear tag assembly 500, more ear tags II530 can be placed in the first through-hole 111 and the tag storage chamber 410, provided that the heights of the ear tags II530 are the same.

In one embodiment, the ear tag II530 is provided with a limiting portion 531 at both sides thereof, and the first through hole 111 and the tag storage cavity 410 are provided with limiting grooves (not shown) at both sides thereof for engaging with the limiting portion 531.
