Preferably, the invention further comprises a bracket 23, wherein the housing 1 is mounted on the bracket 23, and the camera is conveniently mounted and fixed through the supporting connection function of the bracket 23.

When the invention is used, the shell 1 is fixed on the wall surface, the roof and other positions by the bracket 23, and the air is injected into the air bag 8 through the air inlet one-way valve 10 by the air pumping device such as an air cylinder, an air pump and other equipment, along with the entering of the air, the air bag 8 gradually expands and clings to the surfaces of the two lenses 7, meanwhile, the air enters the sinking groove 4 at the right side of the spoiler 5 through the pipeline 9, the pressure of the air inside the sinking groove 4 gradually rises when the air bag 8 can not be expanded continuously, and the high-pressure air in the sinking groove 4 pushes the disc 2 to rotate clockwise until the shooting end of the probe 3 corresponds to the lenses; at this time, gas is continuously injected, the gas injection is stopped when the pressure values in the air bag 8, the pipeline 9 and the sink tank 4 reach the set pressure values, and the gas in the air bag 8 cannot escape due to the unidirectional stopping function of the gas inlet one-way valve 10, so that the disc 2 is kept still.

After the operation is finished, the camera can be normally used as a common camera, and the air bag 8 is made of transparent materials and the interior of the air bag is air, so that the shooting sight of the probe 3 is not influenced, and clear picture quality can be obtained.

When an external force impacts the lens 7 on the left side, one condition is that the lens 7 on the left side is cracked, and the other condition is that the lens 7 is moved rightwards to drive the outer cylinder 14 to slide rightwards; for the first situation, after the lens 7 on the left side is broken, the air bag 8 loses the blocking of the lens 7 on the left side, the high-pressure air inside the air bag makes the air bag 8 expand and explode rapidly, or fragments of the lens 7 after being broken prick or scratch the air bag 8, the air inside the air bag 8 is discharged rapidly and the pressure is reduced, at the moment, the air pressure inside the sinking groove 4 is normal atmospheric pressure and is not enough to overcome the torsion of the torsion spring 11, so the disc 2 rotates anticlockwise under the torsion of the torsion spring 11, and the probe 3 and the lens 7 are staggered to avoid direct impact of external force; when the disc 2 rotates anticlockwise until the shooting end of the probe 3 corresponds to the wide-angle lens 12, the probe 3 captures a picture below the camera through the wide-angle lens 12 and records the picture, so that investigation and evidence collection at the later stage are facilitated; with the continuous anticlockwise rotation of the disc 2, the shooting end of the probe 3 gradually faces to the right side beyond the position of the wide-angle lens 12, the impact of external force acts on the lens 7 on the right side at the moment, and the lens 7 on the right side acts on the disc 2 after being broken and cannot directly act on the probe 3, so that the probe 3 is prevented from being damaged by the impact.

In the second situation, the lens 7 on the left side moves rightwards to enable the outer cylinder 14 to slide rightwards along with the movement, the exhaust hole 18 crosses the position of the flange 15 to lose the blockage, high-pressure gas in the air bag 8, the pipeline 9 and the sink tank 4 is rapidly exhausted through the exhaust hole 18 to reduce the pressure, and the disc 2 rotates anticlockwise under the torsion force of the torsion spring 11 after the pressure is reduced to enable the probe 3 to avoid the impact; after the impact of the external force is finished, the outer cylinder 14 is reset under the elastic force of the spring 17, so that the exhaust hole 18 is closed again.

When an external force acts on the outer cylinder 14, the risk avoiding operation of the probe 3 is the same as the second case.

After the external force impact is finished, the annular end cover 19 is detached, corresponding parts such as the lens 7 and the air bag 8 are replaced, and after the annular end cover 19 is installed again, the air bag 8 is inflated according to the operation and can be used again; during the inflation process of the air bag 8, if the rotation of the disc 2 is blocked, the disc 2 can be directly rotated through the straight groove 22 by using a tool such as a screwdriver, and the like, and the blockage situation of the disc 2 can be found out in time, and corresponding maintenance can be carried out in time, so that the normal work in the subsequent use can be ensured.

The air pressure is utilized to stably keep the probe at a normal shooting position, when the air bag is damaged or exhausted due to external force impact, the probe is timely reversed to realize automatic risk avoidance, shooting and evidence obtaining can be carried out in the reversing process, and direct evidence is provided for later investigation and evidence obtaining; meanwhile, after the probe is reversed, the shooting end of the probe does not face the direction of the impact external force any more, and at the moment, even if the lenses are completely damaged, the disc can effectively resist the external force, so that the probe avoids the direct impact of the external force, and the safety and the integrity of the precise component are protected to the maximum extent.

The invention comprehensively considers the possible occurrence of external force impact, ensures that the probe is reversely rotated and hidden no matter the lens is stressed or the shell is stressed, and effectively protects the safety of the probe and precise components in time; in addition, after the external force strikes, only need to change lens and gasbag and can use once more, greatly reduced unnecessary loss of property.
