Description

Technical Field

[0001] The utility model relates to the field of ear tag clamps, in particular to an ear tag clamp for experimental mice. Background Art

[0002] During animal experiments, in order to distinguish individual animals well, the randomly grouped animals need to be numbered and marked. When marking the mice, it should be ensured that the numbers do not affect the animal's physiology or experimental response, and the numbers should be clear, easy to recognize, durable and applicable.

[0003] At present, the commonly used marking methods for mice and rats mainly include dyeing method, ear hole method, ear number marking, etc. The current ear tag pliers, such as the patent application with publication number CN220123674U proposed in the prior art, install an ear tag needle and an ear tag plate on the ear tag pliers, place the mouse ear between the top plate and the bottom plate, and then squeeze the upper and lower clamp handles to make the upper clamp head push the lower pressure rod downward, and the lower pressure rod pushes the ear tag needle downward into the ear tag plate to complete the ear tag. The needle body of the ear tag needle penetrates vertically downward into the ear tag plate, which is less harmful to the mouse ear than the traditional V-shaped metal ear tag. After squeezing the upper and lower clamp handles to complete the marking, the hand is released, and the upper and lower clamp handles can automatically rebound by the rebound action of the spring. The ear tag needle is clamped at the sunken step, and the ear tag plate is lightly pressed by the pressure plate to prevent the ear tag from falling off during the marking process.

[0004] However, when the experimenter picks up the mouse and aligns the ear and ear tag needle, the mouse's head will struggle, making it difficult for the ear and ear tag needle to be inserted. At the same time, when the ear tag needle is nailed into the ear tag, the mouse feels pain and struggles, and may bite the experimenter's hand, thereby causing harm to the experimenter.

[0005] Therefore, it is necessary to provide an ear tag clamp for experimental mice to solve the above technical problems. Utility Model Content

[0006] The utility model provides an ear tag clamp for experimental mice, which solves the problem that when an experimenter picks up a mouse, the mouse's head struggles and the ear and ear tag needle are inconvenient.

[0007] In order to solve the above technical problems, the utility model provides an ear tag clamp for experimental mice, comprising:

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0026] First embodiment

[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 ,in, Figure 1 This is a schematic structural diagram of a first embodiment of an ear tag clamp for experimental mice provided by the present invention; Figure 2 for Figure 1 A schematic cross-sectional structural diagram of the clamp body shown; Figure 3 for Figure 2 The enlarged schematic diagram of part A is shown. An ear tag clamp for experimental mice, comprising:

[0028] A clamp body 1, one end of which is fixedly connected to a fixing sleeve 5;

[0029] A support frame 2 is provided on one side of the inner wall of the pliers body 1. A sliding hole 3 is provided inside the support frame 2. A lower pliers head 4 is slidably connected to the interior of the support frame 2.

[0030] The movable groove 6 is arranged inside the pliers body 1, and the interior of the movable groove 6 is slidingly connected to two movable blocks 61, the bottom of the movable block 61 is provided with a sliding sleeve 62, the interior of the sliding sleeve 62 is provided with a return spring 63, the interior of the sliding sleeve 62 is slidingly connected to a sliding rod 64, and one end of the sliding rod 64 is fixedly connected to a limiting sleeve 65.

[0031] One end of the support frame 2 is fixedly connected to one side of the inner wall of the clamp body 1, and the lower clamp head 4 is used to install the ear tag needle.

[0032] A rectangular groove is provided inside the sliding sleeve 62, and one end of the sliding rod 64 is fixedly connected to a rectangular block adapted to the rectangular groove, which is used to prevent the limit sleeve 65 from rotating when the sliding rod 64 moves upward into the interior of the sliding sleeve 62. The reset spring 63 is arranged inside the rectangular groove.

[0033] The movable groove 6 is opened inside the pliers body 1 , and the bottoms of the two movable blocks 61 are fixedly connected to the sliding sleeve 62 and one end of the lower pliers head 4 respectively.

[0034] One end of the sliding rod 64 is slidably connected to the inside of the sliding sleeve 62 , and the surface thereof is slidably connected to the inside of the sliding hole 3 .

[0035] The return spring 63 is disposed inside the sliding sleeve 62 and at one end of the sliding rod 64 , and is used to squeeze the return spring 63 when the sliding rod 64 moves upward inside the sliding sleeve 62 .

[0036] The surfaces of the inner walls of the fixing sleeve 5 and the limiting sleeve 65 are both fixedly connected with a protective pad 7 , and the protective pad 7 can be made of sponge, rubber or silicone.

[0037] The protective pad 7 is used to protect the head of the mouse after the fixing sleeve 5 and the limiting sleeve 65 are combined.

[0038] The working principle of the ear tag clamp for experimental mice provided by the utility model is as follows:

[0039] When in use, after placing the mouse's head inside the fixed sleeve 5, the clamp body 1 is pressed and merged, so that the limiting sleeve 65 moves downward and merges with the fixed sleeve 5, and the lower clamp head 4 also moves downward. At the same time, the two moving blocks 61 move to one side inside the two moving grooves 6 respectively.

[0040] When the limiting sleeve 65 is combined with the fixed sleeve 5, while the clamp body 1 is still pressed, the sliding rod 64 moves upward inside the sliding sleeve 62 and squeezes the reset spring 63. At this time, the lower clamp head 4 is still moving to make the needle body of the ear tag needle vertically penetrate into the ear tag. When the clamp body 1 is released and reset, the reset spring 63 pushes the sliding rod 64 to move to one side inside the sliding sleeve 62 to reset, so that the limiting sleeve 65 moves upward and separates from the fixed sleeve 5, and the mouse's head can be taken out.

[0041] Compared with the related art, the ear tag clamp for experimental mice provided by the present invention has the following beneficial effects:

[0042] The utility model provides an ear tag clamp for experimental mice. By placing the mouse's head inside the fixing sleeve 5, when the clamp body 1 is pressed and combined, the limiting sleeve 65 will move downward to limit the mouse's head, thereby preventing the mouse's head from struggling and facilitating the placement of the mouse's ear in a suitable position. At the same time, it also prevents the mouse from feeling pain during marking, biting the experimenter, and causing injury to the experimenter's hands.
