A protective space is defined between an injuring end and a protective end by the protective cover, when shock waves occur, the heat absorption layer absorbs heat, the shock waves enter the energy absorption layer by the porous structure, due to elastic expansion of the energy absorption layer, energy is released, and shock wave energy is reduced, which avoids damage to the external environment and workers, and use is safer. 
     4. High-pressure air is provided for the high-pressure chamber by the external high-pressure generator, such that the high-pressure chamber has an environment with a certain high pressure which is not a working pressure and much smaller than an injuring pressure, which may protect an apparatus. 
     5. Water is added into a high-temperature medium, and is rapidly vaporized to form explosion, resulting in violent moving of the push rod, then the high-pressure film is broken, and strong directional shock waves are formed to cause muscle or bone injury to an animal. 
     6. By means of cooperative use of the accommodation housing, the slide wheel and the slide groove channel, an experimenter may place an animal on the top of the accommodation housing and push the animal into and out of the first storage housing, after an experiment is completed, only the accommodation housing needs to be cleaned, and the interior of the first storage housing does not need to be integrally cleaned, which reducing unnecessary workloads of the experimenter. 
     7. By means of cooperative use of the filtering mechanism sleeve, the locking member and the non-woven fabric, when animal hair moves towards the anti-explosion pipe due to work of the vacuum pump, the animal hair is filtered and intercepted by the sleeve and the non-woven fabric, and the situation that the vacuum pump is blocked due to the fact that the animal hair is sucked into the vacuum pump, and consequently smooth proceeding of scientific experiments is influenced is avoided. 
     8. By means of cooperative use of the inverted U-shaped pipe, the air pump, the pulverized coal igniter and the buffer housing, when an animal needs to be injured by means of burning, the fuel is blown to the pulverized coal igniter by the air pump for ignition, the brand-new inverted U-shaped pipe design is employed, serious burning of the animal due to the fact that the fuel is out of control and used too much is avoided, and on the other hand, an air pump blowing mode is employed, a fuel feeding mode is simplified, gas is used as a medium, the safety of the fuel in the feeding process is improved, further, compared with a traditional ignition mode, the technical solution of some embodiments of the disclosure avoids the problems of fuel gas leakage and high dangerousness, and the problem that the accuracy and the reliability of scientific experiments are influenced due to the fact that a burn area of the animal is possibly too large is directly solved. 
     9. By means of cooperative use of the semiconductor chilling plate, the heat dissipation copper plate, the cold conduction block and the spraying mechanism, on one hand, the purpose of absorbing moisture doped in the fuel is achieved, the combustion efficiency of the fuel is improved, and on the other hand, when an animal burn area is too large due to improper operation of an experimenter or influences of other external factors, the spraying mechanism, the semiconductor chilling plate and the cold conducting block are used in a matching manner in time, low-temperature liquid is sprayed out to cool and extinguish an animal, and accordingly, the safety of a scientific experiment is improved, and the situation that the animal is burnt to be killed is effectively avoided. 
     10. By means of cooperative use of the third electric push rod, the L-shaped fixing plate, the arc-shaped plates, the slide groove channel, the slide groove block and the locking member, an experimenter may slide the slide groove block on the inner side of the slide groove channel in advance so as to drive the two arc-shaped plates to clamp an injured animal body, then the slide groove block is fixed by means of the locking member, and then by utilizing a lifting function of the third electric push rod, an animal is driven by the L-shaped fixing plate to perform injuring operation, thereby effectively solving the problem that the animal goes crazy and attacks the experimenter due to injury pain. 
     11. By means of cooperative use of the non-woven fabric bag, the electric motor and the rotary disc, solute is placed in the non-woven fabric bag, then the electric motor is used for driving the non-woven fabric bag to rotate, meanwhile, the non-woven fabric bag is prevented from being clamped and locked by means of the mobility of the rotary disc, at the moment, solute makes contact with a solvent due to rotation of the non-woven fabric bag, since the solvent is not stirred, a rotation rate of the solvent is relatively lower than that of the solute, then the relative acting force between the solute and the solvent is increased to a certain extent, thereby further increasing the dissolution rate of the solute in the solvent, and the seawater preparation efficiency is improved; and compared with a traditional seawater preparation device, the technical solution of the disclosure gets rid of a stirring and mixing mode of the solvent, and employs a mode of rotationally stirring the solute to increase the relative acting force between the solute and the solvent, thereby achieving the purpose of accelerating the solute to dissolve in the solvent. 
     12. By means of cooperative use of the first electric push rod, the fixing plate, the telescopic sleeve rod, the telescopic rod, the elastic limiting key, the limiting hole, the second electric push rod and the adjustment plate, a user may selectively adjust a height of the first electric push rod and a length between the telescopic sleeve rod and the telescopic rod according to the real-time condition of the field environment, the at least four high-speed cameras are skillfully staring at an animal in the burn process according to hinged connection between the second electric push rod and the adjustment plate, multi-angle high-efficiency photographing is achieved, and the problem of photographing blind spots is avoided; and in addition, according to the technical solution of the disclosure, a free moving function of the universal wheel is utilized, the user can conveniently use and move the device, and moreover, an adjustable photographing is carried out at a periphery of the burnt animal, therefore the safety accident that when the user holds the device, the burnt animal attacks the user is avoided.
