Specifically, as shown in the figure, the anti-shake device described in this embodiment includes a first telescopic rod 9, the mounting base 7 and the box body 5 are both in a cube shape, four parallel first telescopic rods 9 are hinged between the side surface of the mounting base 7 near four corners and the corresponding inner side surface of the box body 5 through ball joints, two parallel connecting rods 10 are hinged between the fixing rods of each two adjacent first telescopic rods 9 on the same side of the mounting base, a plurality of uniformly distributed second elastic telescopic rods 11 are arranged between the two parallel connecting rods 10, the fixed end of each second elastic telescopic rod 11 is fixedly connected with the side surface of one of the connecting rods 10, the movable end of each second elastic telescopic rod 11 is connected with a ball 12 in a rolling manner, the ball 12 keeps contact with and cooperates with the side surface of the other connecting rod 10, the side surface of the connecting rod 10 near the mounting base 7 is hinged with the side surface of the mounting base through a ball joint hinge cylinder 13, a piston 14 is hermetically connected in the cylinder 13, a piston rod 15 is fixedly mounted on the outer end face of the piston 14, the end part of the piston rod 15 is hinged with the corresponding side face of the mounting seat 7 through a ball joint, and a long strip-shaped through hole 16 along the length direction of the cylinder is formed in the position, corresponding to the piston 14, of the side face of the cylinder 13. When the vehicle 1 shakes during running, the box body 5 shakes therewith, the camera 8 moves along with the box body 5 under the action of inertia, under the ideal condition, if the vehicle 1 is supposed to shake only in the direction of the perpendicular line of one surface, two first telescopic rods 9 of the anti-shaking device in the shaking direction of the mounting base 7 are pressed and shortened, the piston rod 15 pushes the piston 14 to move towards the bottom of the cylinder 13, air in the cylinder 13 is discharged through the strip-shaped through hole 16, because the part of the strip-shaped through hole 16 communicated with the bottom of the cylinder 13 is gradually reduced by the movement of the piston 14, the discharging speed of the air in the cylinder 13 is changed from fast to slow, namely the moving resistance of the piston 14 is changed from big to small, when a closed cavity is formed by the bottom of the piston 14 and the bottom of the cylinder 13 and the air in the cavity cannot be continuously compressed, the piston rod 15 cannot continuously move, and the movement state of the anti-shaking device in the transverse position of the mounting base 7 is opposite to the former, meanwhile, the movable ends of the first telescopic rods 9 on the other four surfaces of the mounting seat 7 incline towards the shaking direction of the box body 5, because the two first telescopic rods 9, the side surfaces of the mounting seat 7 and the inner wall of the box body 5 form an unstable parallelogram structure, under the action of the two connecting rods 10, the side surfaces of the mounting seat 7 where the movable ends of the two first telescopic rods 9 are located are always parallel to the corresponding inner wall of the box body 5, at the moment, the corresponding first telescopic rods 9 on the other four surfaces of the mounting seat 7 are all extended, wherein the distance between the corresponding two connecting rods 10 is shortened, the second elastic telescopic rods 11 are compressed and shortened, and the second elastic telescopic rods 11 have resistance for preventing the two connecting rods 10 from approaching each other under the self elastic action, so that the parallelogram structure can be subjected to resistance, the resistance can be applied to the mounting seat 7, the mounting seat 7 is provided with resistance opposite to the moving direction, and the movement resistance of the piston 14 on the moving direction of the mounting seat 7 is matched to change from small to large, the matching of the two resistances can realize that the relative movement speed between the mounting base 7 and the box body 5 can be reduced to zero from quick linear speed and slowly restored to the initial position in the middle of the box body 5, so that the quick rebound and the shake are avoided, and the anti-shake effect on the camera 8 is achieved; the piston 14 moves outwards, the space between the inner end surface of the piston 14 and the bottom of the cylinder 13 is gradually increased, the part of the strip-shaped through hole 16 communicated with the bottom of the cylinder 13 is gradually increased, and air enters the cylinder 13; in the actual working process, the mounting seat 7 can be shaken in any direction due to the acceleration and deceleration of the vehicle 1 and the bumping of the road, because the shaking in any direction, which is received by the mounting seat 7, can be decomposed into X, Y, Z three shaking in the same direction with the three groups of opposite surface perpendicular lines of the mounting seat 7, the shaking in each direction can be subjected to stress analysis through the shaking in the ideal state, the shaking in the single direction on the three groups of opposite surfaces of the mounting seat 7 can be synthesized, therefore, when the vehicle 1 shakes, the anti-shaking devices on the three groups of opposite surfaces on the mounting seat 7 can both play an anti-shaking effect on the camera 8, and the anti-shaking effect can be played on the camera 8 regardless of the shaking of the vehicle 1.

Specifically, as shown in the figure, the arc plates 18 are fixedly installed on the front side and the rear side of the top surface of the base 2, the cross rod 19 is fixedly installed between the concave surfaces of the two arc plates 18, the cross rod 19 is located between the two belts 4, and the plurality of lint brushes 20 are installed on the left side and the right side of the cross rod 19 at equal intervals along the length direction. When the belt roller 3 rotates to drive the corresponding belt 4 to rotate, the camera 8 on the side of the belt 4 rotates along with the belt 4, when the camera 8 rotates to the fluff brush 20, the camera 8 can be brushed down by the fluff brush 20 due to dust accumulated outdoors for a long time, so that the pictures shot by the camera 8 in the patrol process of the police car are always clear, the camera can be cleaned in time when being applied to a severe environment, the image detection is stable and clear, meanwhile, the arc-shaped plate 18 and the arc-shaped parts of the two belts 4 form a complete round-like shape close to the streamline shape, the streamline shape can enable the air flow at the periphery of the equipment on the roof to be more stable, the occurrence of turbulence is reduced, the more stable air flow can reduce the shaking of the equipment, the occurrence of phenomena such as resonance and the like is reduced, the anti-shaking effect of the equipment is further improved, and the resistance of the equipment is reduced.

Further, as shown in the figure, an annular elastic cloth 21 is fixedly installed between the side surface of the first through hole 6 and the side surface of the camera 8. When the vehicle was when driving, through blockking of elastic cloth 21, can prevent that wind from pouring into in the box body 5 through first through-hole 6 to reduce the windage that the vehicle travel, and wind to the influence of device anti-shake effect, when camera 8 took place the skew along with the anti-shake device, elastic cloth 21 can produce the deformation, guaranteed the reliability of anti-shake effect.

Furthermore, as shown in the figure, the upper side of the base 2 in the embodiment is provided with an oval top plate 22, the bottom surface of the oval top plate 22 is rotatably connected with the upper end of the shaft of the belt roller 3, and the edge of the oval top plate 22 is rounded.
