The following describes a specific method of using the observation device for observing animal activity and fixing the head of the animal.

Before use, the fixing member 133 is surgically fixed on the head of the animal; specifically, a cranial nail or dental cement can be used for fixation; wherein, the specific implementation process of the cranial nail or dental cement for fixing can be found in Existing technology, and can achieve the same or similar technical effects, which will not be repeated here; and when in use, in order to facilitate installation and reduce the discomfort of animals, the animal can be gas anesthetized first, and then the head of the animal is passed through. The gap between the two middle straps 141, the left and right forelimbs pass through the gap between the two sides and the middle strap 141 respectively. For details, please refer to FIG. 9, which is a strap and an animal body provided by an embodiment of the application. Schematic diagram of fixing, and then fix the head of the animal; specifically, snap the fixing piece 133 into the limiting groove 135, and screw the two fixing knobs 1325 to fix the fixing piece 133 and the spherical platform 1323; then Adjust the limiter 1312 according to the current position of the animal's head to fix the first telescopic rod 1311 at a suitable height, and adjust the clamping arm locking valve 1326 to the correct angle and position of the ball platform 1323, so that the The animal's head can move normally; after fixing the animal's head, adjust the sliding rod 1421 to a suitable position on the support platform 121 and fix it with the fixing block 1422, and rotate the second telescopic rod 1423 so that the second telescopic rod 1423 faces Move away from the support platform 121, and then tighten the straps 141, so that the support platform 121 is fixed with the animal's body, and then the animal's body drives the support platform 121 to move at the same time. Probability of fractures; experiments were then started when animals were awake.

Specifically, the above-mentioned animals can be mice; of course, in other embodiments, the above-mentioned animals can also be other similar reptiles, rodents or larger mammals, such as dogs, cats Wait.

The observation device for observing animal activities provided above is not only small in size and light in weight, but also cheap and affordable; at the same time, the device requires less site and can be used even in a very small space; and the device can be placed In the existing various plane fields, there is no need to make a special field; in addition, the structure of the device is simple and reliable, and there is no complicated circuit, which is convenient for use, cleaning, maintenance, repair or replacement of parts.

It should be noted that the observation assembly involved in the present application is not limited to the observation equipment in the prior art, and may be other operation equipment, such as a motor, a camera, etc., which is not limited in this embodiment.

The above are only the embodiments of the present application, and are not intended to limit the scope of the patent of the present application. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present application, or directly or indirectly applied in other related technical fields, All are similarly included in the scope of patent protection of the present application.
