Placement device beneficial to analysis of vital signs of mice

The invention relates to the technical field of pharmacological experiment equipment, and discloses a placement device beneficial to analysis of vital signs of a mouse. The first friction plate is fixedly arranged at the end part of one horizontal rotating shaft and rotates along with the glass cage body; the gas type rotating structure is arranged above the bottom fixed base plate; the friction surface of the gas type rotating structure is propped against the plate surface of the first friction plate; the driving motor is mounted above the bottom fixing base plate and can drive the gas type rotating structure to rotate. According to the arrangement device beneficial to analysis of the vital signs of the mice, the friction force between the driving motor and the glass cage body during rotation is controlled through gas pressure, and the rotation trend of the friction force on the glass cage body is consistent with the movement direction of the mice; therefore, rolling friction resistance existing between rota
