The ear tag magazine 50 comprises a magazine 51, the magazine 51 having a first end remote from the guide slot 13 and a second end adjacent to the guide slot 13, opposite the first end. The body 51 has a channel formed therein for allowing the ear tag 40 to move from the first end to the second end under the action of external force, and the channel may have a substantially triangular shape corresponding to the ear tag 40, or may have a square, circular or other shape. The first end is provided with a first push plate 57 positioned in the box body 51 and a label sending spring 56 for connecting the first push plate 57 with the inner wall of the box body 51, and the shape of the first push plate 57 is adapted to the shape of the channel. The second end is provided with a first side close to the guide groove 13 and a second side opposite to the first side, the first side is provided with a label feeding port 52 positioned under the guide groove 13, the size of the label feeding port 52 is matched with that of the ear tag 40, the second side is provided with a label pushing port 53 opposite to the label feeding port 52, and the size of the label pushing port 53 is the same as that of the label feeding port 52. The second side is provided with a pushing device 60 which pushes the ear tag 40 away from the tag pushing opening 53 and sends the ear tag into the guide groove 13 through the tag sending opening 52.

The pushing device 60 comprises a second pushing plate 61, a pushing rod 62 and a supporting mechanism, wherein the second pushing plate 61 has a first surface contacting with the ear tag 40 and a second surface opposite to the first surface, and the first surface is provided with a closing groove 611 for forming a closing structure of the ear tag 40 under the pressing of the second jaw 21. Preferably, the second push plate 61 is slidably fitted to the guide groove 13. Two opposite L-shaped supporting plates 58 and two opposite baffle plates 59 are fixed outside the second side of the second end of the box body 51, the two supporting plates 58 and the two baffle plates 59 are arranged around the label pushing opening 53, so that the two supporting plates 58 and the two baffle plates 59 form an accommodating cavity 510 capable of accommodating the second push plate 61, the supporting plates 58 have elasticity, and the second push plate 61 can be placed into the accommodating cavity 510 after the supporting plates 58 are elastically deformed. After the second support plate 58 is located in the receiving cavity 510, the first surface of the second push plate 61 is not higher than the bottom surface of the ear tag 40, so as to ensure that the ear tag 40 in the box 51 can move smoothly onto the first surface of the second push plate 61 under the action of the tag feeding spring 56 and the first push plate 57. One end of the push rod 62 is fixedly connected with the second surface of the second push plate 61, and the other end is provided with the supporting mechanism, preferably, the width or diameter of the push rod 62 is the same as the width of the second push plate 61 and the width of the ear tag 40. The support mechanism is used for supporting the second push plate 61 pushed into the guide groove 13.

The working principle is as follows: when the ear tag box 50 is filled with the ear tag 40, under the action of the first push plate 57 and the tag feeding spring 56, one ear tag 40 is always supported and abutted against the inner wall of the second end of the box body 51 in the box body 51, and the ear tag 40 is just positioned between the tag feeding port 52 and the tag pushing port 53, then an experimenter pushes the push rod 62 by hand, so that the second push plate 61 pushes one ear tag 40 out of the box body 51, the ear tag 40 moves from one end, close to the tag feeding port 52, of the guide groove 13 to one end, far away from the tag feeding port 52, when the top of the ear tag 40 is abutted against the inner side of the second jaw 21, and the bottom is positioned in the guide groove 13 again and abutted against the second push plate 61, the second push plate 61 can be kept in the position abutted against the bottom of the ear tag 40 by the support mechanism, and the ear tag 40 is provided with a support. Since the shape of the guide groove 13 is adapted to the shape of the bottom of the ear tag 40, the ear tag 40 is not easily moved, and the top of the ear tag 40 is just in abutment with the inner side support of the second jaw 21, so that the ear tag 40 is supported between the first jaw 11 and the second jaw 21. Then the experimenter presses the first forceps handle 12 and the second forceps handle 22 to close the first forceps mouth 11 and the second forceps mouth 21, the second push plate 61 is kept still due to the function of the supporting mechanism, under the pressing of the second forceps mouth 21, the tip of the top of the ear tag 40 passes through the ear of the experimental rat and is buckled into the hole of the bottom, so that the ear tag 40 forms a closed structure, and the ear tag 40 is fixed on the ear of the experimental rat. By operating the supporting mechanism, the second push plate 61 is returned to the housing chamber 510 to prepare for pushing out the next ear tag 40. During the process of punching the ear tag 40, the push rod 62 is kept in contact with the ear tag 40 in the box 51, so that the second push plate 61 can smoothly return to the accommodating cavity 510.

According to the ear tag 40 clamp for the experimental mouse, provided by the invention, the ear tag 40 can be replaced under simple operation, and the ear tag 40 is stably placed between the first clamp mouth 11 and the second clamp mouth 21, so that an experimenter can conveniently perform ear tag 40 marking operation on the experimental mouse, the single marking time is shortened, and the ear tag 40 marking efficiency is further improved.

As a further improvement of the above solution, the supporting mechanism includes a wedge-shaped block 63, a supporting arm 64 and a tension spring 65, the wedge-shaped block 63 is fixedly connected to an outer wall of the second end of the ear tag box 50, one end of the supporting arm 64 is a supporting portion 641 which is matched with the wedge-shaped block 63 and is wedge-shaped, and the other end of the supporting arm 64 is a pressing portion 642, and a portion of the supporting arm 64 close to the pressing portion 642 is hinged to the other end of the push rod 62 through a hinge; two ends of the tension spring 65 are respectively connected with the push rod 62 and the support arm 64, although the tension spring 65 can be replaced by a torsion spring, the torsion spring has the disadvantage of inconvenient installation. In addition, a wedge-shaped stop 63, a support arm 64 and an elastic member are preferably disposed on both sides of the push rod 62, so that the structure is symmetrical and the support effect is better. When the two pressing portions 642 are pressed, the supporting portions 641 of the two supporting arms 64 are disengaged from the two wedge-shaped stoppers 63 on the outer wall of the box 51, so that the second pushing plate 61 can be pulled back into the accommodating cavity 510 by the pushing rod 62. The supporting mechanism has the advantage of convenience in operation.
