The adapter ear rod for mice and young mice is made of resin and has a suitable taper treatment on the tip, which can firmly clamp the mouse head and avoid damage to the mouse skull caused by using stainless steel as the ear rod. The height of the ear bars on both sides and the height of the door gear clamp can be freely adjusted, and they are equipped with scales, suitable for experiments at different angles.

1. Use in conjunction with a positioning device for positioning, injection, EEG recording, brain imaging, and other related experiments;
2. Independent use: Fix the head and conduct further experiments on the legs, back, and other areas.

1. Fix the mouse head by "fastening the front teeth, pressing the nose bridge, and inserting the ear canal";
2. Ear rod adjustment: adjustable up and down, left and right positions, both can be smoothly fine tuned;
3. Nose and mouth clip adjustment: The up and down, front and back positions can be adjusted smoothly and finely;
4. The adjustment of the ear rod and nose nozzle clip consists of three steps: loosening the screw - pushing the ear rod - tightening the screw, reducing the repeated "loosening tightening" operation steps and improving efficiency;
5. The ear rod and nose clip are both adjusted up and down with scale markings.
